Re: [PATCH v2 07/14] [media] s5p-mfc: Don't crash the kernel if the watchdog kicks in.

2014-10-21 Thread Arun Kumar K
Hi Kamil,

Kiran will not be available to handle review comments of these patches.
So I will be pushing the updated patchset rebased on media-tree.

I hope all patches are good to merge except
[media] s5p-mfc: Don't change the image size to smaller than the request.

I will drop this one patch and send all others in v3 version.

Regards
Arun

 Subject: [PATCH v2 07/14] [media] s5p-mfc: Don't crash the kernel if
 the watchdog kicks in.

 From: Pawel Osciak posc...@chromium.org

 If the software watchdog kicks in, the watchdog worker is not
 synchronized with hardware interrupts and does not block other
 instances. It's possible for it to clear the hw_lock, making other
 instances trigger a BUG() on hw_lock checks. Since it's not fatal to
 clear the hw_lock to zero twice, just WARN in those cases for now. We
 should not explode, as firmware will return errors as needed for other
 instances after it's reloaded, or they will time out.

 A clean fix should involve killing other instances when watchdog kicks
 in, but requires a major redesign of locking in the driver.

[PATCH v3 03/13] [media] s5p-mfc: clear 'enter_suspend' flag if suspend fails

2014-10-21 Thread Arun Kumar K
From: Prathyush K prathyus...@samsung.com

The enter_suspend flag is set after we enter mfc suspend function but if
suspend fails after that due to any reason (like hardware timeout etc),
this flag must be cleared before returning an error. Otherwise, this
flag never gets cleared and the MFC suspend will always return an error
on subsequent tries. If clock off fails, disable hw_lock also.

[PATCH v3 04/13] [media] s5p-mfc: Only set timestamp/timecode for new frames.

2014-10-21 Thread Arun Kumar K
From: Ilja Friedel i...@chromium.org

Timestamp i of a previously decoded buffer was overwritten for some
H.264 streams with timestamp i+1 of the next buffer. This happened when
encountering frame_type S5P_FIMV_DECODE_FRAME_SKIPPED, indicating no
new frame.

In most cases this wrong indexing might not have been noticed except
for a one frame delay in frame presentation. For H.264 streams though
that require reordering of frames for presentation, it caused a slightly
erratic presentation time lookup and consequently dropped frames in the
Pepper Flash plugin.

[PATCH v3 06/13] [media] s5p-mfc: check mfc bus ctrl before reset

2014-10-21 Thread Arun Kumar K
From: Kiran AVND avnd.ki...@samsung.com

during reset sequence, it is advisable to follow the below
sequence, in order to avoid unexpected behavior from MFC
. set SFR 0x7110 MFC_BUS_RESET_CTRL 0x1
  // wait for REQ_STATUS to be 1
. get SFR 0x7110 MFC_BUS_RESET_CTRL 0x3
  // reset now

[PATCH v3 07/13] [media] s5p-mfc: Don't crash the kernel if the watchdog kicks in.

2014-10-21 Thread Arun Kumar K
From: Pawel Osciak posc...@chromium.org

If the software watchdog kicks in, the watchdog worker is not synchronized
with hardware interrupts and does not block other instances. It's possible
for it to clear the hw_lock, making other instances trigger a BUG() on
hw_lock checks. Since it's not fatal to clear the hw_lock to zero twice,
just WARN in those cases for now. We should not explode, as firmware will
return errors as needed for other instances after it's reloaded, or they
will time out.

A clean fix should involve killing other instances when watchdog kicks in,
but requires a major redesign of locking in the driver.

[PATCH v3 10/13] [media] s5p-mfc: flush dpbs when resolution changes

2014-10-21 Thread Arun Kumar K
From: Kiran AVND avnd.ki...@samsung.com

While resolution change is detected by MFC, we flush out
older dpbs, send the resolution change event to application,
and then accept further queuing of new src buffers.

Sometimes, we error out during dpb flush because of lack of src
buffers. Since we have not started decoding new resolution yet,
it is simpler to push zero-size buffer until we flush out all dpbs.

This is already been done while handling EOS command, and this patch
extends the same logic to resolution change as well.

2014-10-21 Thread Arun Kumar K
From: Pawel Osciak posc...@chromium.org

Interrupt result flags have to be cleared before a hardware job is run.
Otherwise, if they are cleared asynchronously, we may end up clearing them
after the interrupt for which we wanted to wait has already arrived, thus
overwriting the job results that we intended to wait for.

To prevent this, clear the flags only under hw_lock and before running
a hardware job.

[PATCH v3 12/13] [media] s5p-mfc: fix V4L2_CID_MIN_BUFFERS_FOR_CAPTURE on resolution change.

2014-10-21 Thread Arun Kumar K
From: Pawel Osciak posc...@chromium.org

G_CTRL on V4L2_CID_MIN_BUFFERS_FOR_CAPTURE will fail if userspace happens to
query it after getting a resolution change event and before the codec has
a chance to parse the header and switch to an initialized state.

 Out of all MFC versions, only v6 doesn't use special clock at all.

Agree to your point above that some SoCs may have different hierarchy
which needs
to enable this clock explicitly. But other SoCs using v5, v7 and v8
still works fine
without this special clock and those DT nodes doesnt provide this clock now.
So I would suggest not to error return if the clock is not provided
and keep it as
an optional parameter to maintain backward compatibility. With this
current patch
all the working SoCs like 5420, 5800 etc will fail in probe.

Arun

This patch adds the support of accepting multiple firmware
binaries for every version with the driver trying to load

[PATCH 2/3] [media] s5p-mfc: Support multiple firmware sub-versions

2014-05-20 Thread Arun Kumar K
For MFC firmwares, improved versions with bug fixes and
feature additions are released keeping the firmware version
including major and minor number same. The issue came with
the release of a new MFCv6 firmware with an interface change.
This patch adds the support of accepting multiple firmware
binaries for every version with the driver trying to load
firmwares starting from latest. This ensures full backward
compatibility regardless of which firmware version and kernel
version is used.

VP8 encodig is supported only from v7 onwards.
So you can remove MFC_V6 from this.

Otherwise looks good to me.

[PATCH 06/10] [media] s5p-mfc: Don't try to resubmit VP8 bitstream buffer for decode.

2014-05-19 Thread Arun Kumar K
From: Pawel Osciak posc...@chromium.org

Currently, for formats that are not H264, MFC driver will check
the consumed stream size returned by the firmware and, based on that,
will try to decide whether the bitstream buffer contained more than
one frame. If the size of the buffer is larger than the consumed
stream, it assumes that there are more frames in the buffer and that the
buffer should be resubmitted for decode. This rarely works though and
actually introduces problems, because:

- v7 firmware will always return consumed stream size equal to whatever
the driver passed to it when running decode (which is the size of the whole
buffer), which means we will never try to resubmit, because the firmware
will always tell us that it consumed all the data we passed to it;

- v6 firmware will return the number of consumed bytes, but will not
include the padding (stuffing) bytes that are allowed after the frame
in VP8. Since there is no way of figuring out how many of those bytes
follow the frame without getting the frame size from IVF headers (or
somewhere else, but not from the stream itself), the driver tries to guess that
padding size is not larger than 4 bytes, which is not always true;

The only way to make it work is to queue only one frame per buffer from
userspace and the check in the kernel is useless and wrong for VP8.
So adding VP8 also along with H264 to disallow re-submitting of buffer
back to hardware for decode.

[PATCH 01/10] [media] s5p-mfc: Copy timestamps only when a frame is produced.

2014-05-19 Thread Arun Kumar K
From: Pawel Osciak posc...@chromium.org

Timestamps for destination buffers are assigned by copying them from
corresponding source buffers when the decode operation results in a frame
being outputted to a destination buffer. But the decision when to do this, i.e.
whether the decode operation on current source buffer produced a destination
frame, is wrongly based on display status. Display status reflects the status
of the destination buffer, not source.

This used to work for firmwares version = 6, because in addition to the above,
we'd check the decoded frame type register, which was set to skipped if
a destination frame was not produced, exiting early from
s5p_mfc_handle_frame_new().
Firmware =7 does not set the frame type register for frames that were not
decoded anymore though, which results in us wrongly overwriting timestamps of
previously decoded buffers (firmware reports the same destination buffer address
as previously decoded one if a frame wasn't decoded during current operation).

To do it properly, we should be basing our decision to copy the timestamp on the
status of the source buffer, i.e. decode status. The decode status register
values are confusing, because in its case display means a frame has been
outputted to a destination buffer. We should copy if decode and display
is returned in it. This also works on = v6 firmware, which behaves in the same
way with regards to decode status register.

[PATCH 02/10] [media] s5p-mfc: Fixes for decode REQBUFS.

2014-05-19 Thread Arun Kumar K
From: Pawel Osciak posc...@chromium.org

- Honor return values from vb2_reqbufs on REQBUFS(0).

- Do not set the number of allocated buffers to 0 if userspace tries
  to request buffers again without freeing them.

- There is no need to verify correct instance state on reqbufs, as we will
  verify this in queue_setup().

- There is also no need to verify that vb2_reqbufs() was able to allocate enough
  buffers (pb_count) and call buf_init on that many buffers (i.e. dst_buf_count
  is at least pb_count), because this will be verified by second queue_setup()
  call as well and vb2_reqbufs() will fail otherwise.

- Only verify state is MFCINST_INIT when allocating, not when freeing.

- Refactor and simplify code.

[PATCH 04/10] [media] s5p-mfc: Don't allocate codec buffers on STREAMON.

2014-05-19 Thread Arun Kumar K
From: Pawel Osciak posc...@chromium.org

Currently, we allocate private codec buffers on STREAMON, which may fail
if we are out of memory. We don't check for failure though, which will
make us crash with the codec accessing random memory.

We shouldn't be failing STREAMON with out of memory errors though. So move
the allocation of private codec buffers to REQBUFS for OUTPUT queue. Also,
move MFC instance opening and closing to REQBUFS as well, as it's tied to
allocation and deallocation of private codec buffers.

 So we used to allow STREAMON on the CAPTURE plane only after

 header is generated and checked with the minimum buffer requirement.

 But this causes a problem that we call a vb2_buffer_done for the
 sequence header buffer before doing a STREAON on the CAPTURE plane.

 How could this ever have worked? Buffers aren't queued to the driver
 until STREAMON is called, and calling vb2_buffer_done for a buffer
 that is not queued first to the driver will mess up internal data (q-
 queued_count for one).


 This worked till now because __enqueue_in_driver is called first and
 then start_streaming qop is called. In MFCv6, the start_streaming
 driver callback used to wait till sequence header interrupt is received
 and it used to do vb2_buffer_done in that interrupt context. So it
 happened after buffers are enqueued in driver and before completing the
 vb2_streamon.

 This used to still work fine until this patch was merged -
 b3379c6 : vb2: only call start_streaming if sufficient buffers are
 queued

 Are you testing with CONFIG_VIDEO_ADV_DEBUG set? If not, you should
 do
 so. That will check whether all the vb2 calls are balanced.

 BTW, that's a small typo in s5p_mfc_enc.c (search for 'inavlid').


 I got it. Will post a patch fixing them. Thanks for spotting this.

 This problem should also come in earlier MFC firmware versions if
 the
 application calls STREAMON on CAPTURE with some delay after doing
 STREAMON on OUTPUT.

 You can also play around with the min_buffers_needed field. My
 rule-of-thumb is that when start_streaming is called everything
 should
 be ready to stream. It is painful for drivers to have to keep track
 of the 'do I have enough buffers' status.

 For that reason I introduced the min_buffers_needed field. What I
 believe you can do here is to set it initially to a large value,
 preventing start_streaming from being called, and once you really
 know
 the minimum number of buffers that you need it can be updated again
 to the actual value.

 If a large value is kept in min_buffers_needed, there will be some
 unnecessary memory initialization needed for say 16 full HD raw YUV
 buffers when actual needed is only 4. And once the encoding is started,
 updating the min_buffers_needed to actual value doesnt give any
 advantage as nobody checks for it after that.
 So the whole idea is to not enforce a worst case buffer allocation
 requirement beforehand itself. I hope the current scheme of things
 works well for the requirement.
 
 I was looking in the code of the MFC encoder and handling of this situation
 seems wrong to me.
 
 You say that a minimum number of buffers has to be queued for MFC encoder to
 work. But this number is not checked in s5p_mfc_ctx_ready in s5p_mfc_enc.c.
 

The situation is bit tricky here. The s5p_mfc_ctx_ready has to be true
for giving the first frame to encode which generates the sequence
header. So this condition still holds good -
/* context is ready to make header */
if (ctx-state == MFCINST_GOT_INST  ctx-dst_queue_cnt = 1)
return 1;

So at this moment, atleast 1 buffer has to be queued in CAPTURE plane so
as to generate sequence header. But once that is generated, then only
the total buffer requirement will be known as per the v6+ firmware.
So if we make ctx_ready only after STREAMON on CAPTURE is done, then
there is no way to check for min. buffer requirement and the application
will start the encoding and will fail during runtime.

 It is only checked during reqbufs. This way it does not ensure that there is
 a minimum number of buffers queued.
 
 Also there is a control V4L2_CID_MIN_BUFFERS_FOR_CAPTURE, maybe it could be
 used
 in this context?
 

We had a discussion on this sometime back when a sequence change was
proposed for encoding.
http://www.mail-archive.com/linux-media%40vger.kernel.org/msg60400.html

But we kept the old sequence for backward compatibility with old
applications. If the application had requested buffers  streamon on
CAPTURE plane first, then this issue will not come as the minimum OUTPUT
buffer requirement is checked in the REQBUF for OUTPUT.
So the best sequence would be
1) REQBUF on CAPTURE
2) QBUF and STREAMON on CAPTURE
3) REQBUF on OUTPUT (Will know at this time the minimum OUTPUT buffer
requirement)

But if an application follows the following sequence:
1) REQBUF on OUTPUT (we dont know the min. number yet)
2) REQBUF on CAPTURE
3) STREAMON on OUTPUT (header generated)
4) STREAMON on CAPTURE (check for min. OUTPUT

[PATCH v3] [media] s5p-mfc: add init buffer cmd to MFCV6

2014-05-14 Thread Arun Kumar K
From: avnd kiran avnd.ki...@samsung.com

Latest MFC v6 firmware requires tile mode and loop filter
setting to be done as part of Init buffer command, in sync
with v7. Since there are two versions of v6 firmware with
different interfaces, it is differenciated using the version
number read back from firmware which is a hexadecimal value
based on the firmware date.

[PATCH v2] [media] s5p-mfc: Don't allocate codec buffers on STREAMON.

2014-05-14 Thread Arun Kumar K
From: Pawel Osciak posc...@chromium.org

Currently, we allocate private codec buffers on STREAMON, which may fail
if we are out of memory. We don't check for failure though, which will
make us crash with the codec accessing random memory.

We shouldn't be failing STREAMON with out of memory errors though. So move
the allocation of private codec buffers to REQBUFS for OUTPUT queue. Also,
move MFC instance opening and closing to REQBUFS as well, as it's tied to
allocation and deallocation of private codec buffers.

[PATCH v2] [media] s5p-mfc: Dequeue sequence header after STREAMON

2014-05-14 Thread Arun Kumar K
MFCv6 encoder needs specific minimum number of buffers to
be queued in the CAPTURE plane. This minimum number will
be known only when the sequence header is generated.
So we used to allow STREAMON on the CAPTURE plane only after
sequence header is generated and checked with the minimum
buffer requirement.

But this causes a problem that we call a vb2_buffer_done
for the sequence header buffer before doing a STREAON on the
CAPTURE plane. This used to still work fine until this patch
was merged -
b3379c6 : vb2: only call start_streaming if sufficient buffers are queued

This problem should also come in earlier MFC firmware versions
if the application calls STREAMON on CAPTURE with some delay
after doing STREAMON on OUTPUT.

So this patch keeps the header buffer until the other frame
buffers are ready and dequeues it just before the first frame
is ready.

[PATCH] [media] s5p-mfc: Update scratch buffer size for MPEG4

2014-05-14 Thread Arun Kumar K
Update the MPEG4 decoder scratch buffer size as per the
new v6 firmware. This updation is increasing the size and so
is backward compatible with older v6 firmwares.

[PATCH v2 0/4] Add MFCv8 support

2014-05-14 Thread Arun Kumar K
This patchset adds MFCv8 support to the s5p-mfc driver.
MFCv8 has the same operation sequence as that of v6+, but
there is some shuffling of the registers happened. So to
re-use the exisiting code, register access uses context
variables instead of macros.
The patchset modifies opr_v6 file to use register variables
and is tested on mfc v5, v6, v7 and v8 based boards.

The patchset is based on the following set of patches
posted for MFC which are currently under review:

s5p-mfc: Update scratch buffer size for MPEG4
s5p-mfc: Add support for resolution change event
v4l: Add source change event
s5p-mfc: Don't try to resubmit VP8 bitstream buffer for decode.
s5p-mfc: Update scratch buffer size for VP8 encoder
s5p-mfc: Dequeue sequence header after STREAMON
s5p-mfc: Don't allocate codec buffers on STREAMON.
s5p-mfc: Extract open/close MFC instance commands.
s5p-mfc: Fixes for decode REQBUFS.
s5p-mfc: Copy timestamps only when a frame is produced.
s5p-mfc: add init buffer cmd to MFCV6
s5p-mfc: Add a control for IVF format for VP8 encoder

Changes from v1
- Included encoder support for v8 patch
- Addressed review comments from Kamil  Sachin

[PATCH v5 1/2] [media] v4l: Add source change event

2014-05-14 Thread Arun Kumar K
This event indicates that the video device has encountered
a source parameter change during runtime. This can typically be a
resolution change detected by a video decoder OR a format change
detected by an input connector.

This needs to be nofified to the userspace and the application may
be expected to reallocate buffers before proceeding. The application
can subscribe to events on a specific pad or input port which
it is interested in.

[PATCH v5 2/2] [media] s5p-mfc: Add support for resolution change event

2014-05-14 Thread Arun Kumar K
From: Pawel Osciak posc...@chromium.org

When a resolution change point is reached, queue an event to signal the
userspace that a new set of buffers is required before decoding can
continue.

Re: [PATCH v2] [media] s5p-mfc: Dequeue sequence header after STREAMON

2014-05-14 Thread Arun Kumar K
Hi Hans,

 On 05/14/2014 08:29 AM, Arun Kumar K wrote:
 MFCv6 encoder needs specific minimum number of buffers to
 be queued in the CAPTURE plane. This minimum number will
 be known only when the sequence header is generated.
 So we used to allow STREAMON on the CAPTURE plane only after
 sequence header is generated and checked with the minimum
 buffer requirement.

 But this causes a problem that we call a vb2_buffer_done
 for the sequence header buffer before doing a STREAON on the
 CAPTURE plane. 
 
 How could this ever have worked? Buffers aren't queued to the driver until
 STREAMON is called, and calling vb2_buffer_done for a buffer that is not 
 queued
 first to the driver will mess up internal data (q-queued_count for one).
 

This worked till now because __enqueue_in_driver is called first and
then start_streaming qop is called. In MFCv6, the start_streaming driver
callback used to wait till sequence header interrupt is received and it
used to do vb2_buffer_done in that interrupt context. So it happened
after buffers are enqueued in driver and before completing the vb2_streamon.

 This used to still work fine until this patch
 was merged -
 b3379c6 : vb2: only call start_streaming if sufficient buffers are queued
 
 Are you testing with CONFIG_VIDEO_ADV_DEBUG set? If not, you should do so. 
 That
 will check whether all the vb2 calls are balanced.
 
 BTW, that's a small typo in s5p_mfc_enc.c (search for 'inavlid').
 

I got it. Will post a patch fixing them. Thanks for spotting this.

 This problem should also come in earlier MFC firmware versions
 if the application calls STREAMON on CAPTURE with some delay
 after doing STREAMON on OUTPUT.
 
 You can also play around with the min_buffers_needed field. My rule-of-thumb 
 is that
 when start_streaming is called everything should be ready to stream. It is 
 painful
 for drivers to have to keep track of the 'do I have enough buffers' status.
 
 For that reason I introduced the min_buffers_needed field. What I believe you 
 can
 do here is to set it initially to a large value, preventing start_streaming 
 from
 being called, and once you really know the minimum number of buffers that you 
 need
 it can be updated again to the actual value.

If a large value is kept in min_buffers_needed, there will be some
unnecessary memory initialization needed for say 16 full HD raw YUV
buffers when actual needed is only 4. And once the encoding is started,
updating the min_buffers_needed to actual value doesnt give any
advantage as nobody checks for it after that.
So the whole idea is to not enforce a worst case buffer allocation
requirement beforehand itself. I hope the current scheme of things works
well for the requirement.

Regards
Arun

 
 I don't know this driver well enough to tell whether that works here or not, 
 but
 it is worth looking at IMHO.
 
 Regards,
 
   Hans
 
 So this patch keeps the header buffer until the other frame
 buffers are ready and dequeues it just before the first frame
 is ready.

[PATCH v4 1/2] [media] v4l: Add source change event

2014-05-13 Thread Arun Kumar K
This event indicates that the video device has encountered
a source parameter change during runtime. This can typically be a
resolution change detected by a video decoder OR a format change
detected by an HDMI connector.

This needs to be nofified to the userspace and the application may
be expected to reallocate buffers before proceeding. The application
can subscribe to events on a specific pad or input port which
it is interested in.

 two versions of v6 firmware with different interfaces, it is

 I would replace this by:

 static const struct v4l2_event ev_src_ch = {
 .type = V4L2_EVENT_SOURCE_CHANGE,
 .u.src_change.changes = V4L2_EVENT_SRC_CH_RESOLUTION,
 };

 No need for memsets or filling in structs at runtime.


Ok will make this change.

 Subject: [PATCH 1/3] [media] s5p-mfc: Add variants to access mfc
 registers

 From: Kiran AVND avnd.ki...@samsung.com

 This patch is needed in preparation to add MFC V8
 where the register offsets are changed w.r.t MFC V6/V7.

 This patch adds variants of MFC V6 and V7 while
 accessing MFC registers. Registers are kept in mfc context
 and are initialized to a particular MFC variant during probe,
 which is used instead of macros.

 This avoids duplication of the code for MFC variants
 V6  V7, and reduces the if_else checks while accessing
 registers of different MFC variants.

 MFCv6 encoder needs specific minimum number of buffers to
 be queued in the CAPTURE plane. This minimum number will
 be known only when the sequence header is generated.
 So we used to allow STREAMON on the CAPTURE plane only after
 sequence header is generated and checked with the minimum
 buffer requirement.

 But this causes a problem that we call a vb2_buffer_done
 for the sequence header buffer before doing a STREAON on the
 CAPTURE plane. This used to still work fine until this patch
 was merged b3379c6201bb3555298cdbf0aa004af260f2a6a4.

 Please provide the patch title too along with commit ID
 (first 12 characters of ID is enough).


 This problem should also come in earlier MFC firmware versions
 if the application calls STREAMON on CAPTURE with some delay
 after doing STREAMON on OUTPUT.

 So this patch keeps the header buffer until the other frame
 buffers are ready and dequeues it just before the first frame
 is ready.

[PATCH v3 0/2] Add resolution change event

This patchset adds a source_change event to the v4l2-events.
This can be used for notifying the userspace about runtime
format changes happening on video nodes / pads like resolution
change in video decoder.

This version includes suggestions from Hans and Laurent
to make it more generic and to be used by all kinds of
video devices to notify userspace about runtime parameter
changes. The discussion can be seen here [1]

If this is accepted, I can send another series implementing
v4l2_event_init() for zeoring the data array addressing
compatibility issues as discussed in [1].

[PATCH v3 1/2] [media] v4l: Add source change event

2014-05-08 Thread Arun Kumar K
This event indicates that the video device has encountered
a source parameter change during runtime. This can typically be a
resolution change detected by a video decoder OR a format change
detected by an HDMI connector.

This needs to be nofified to the userspace and the application may
be expected to reallocate buffers before proceeding. The application
can subscribe to events on a specific pad or input/output port which
it is interested in.

 From: Pawel Osciak posc...@chromium.org

 Currently, for formats that are not H264, MFC driver will check the
 consumed stream size returned by the firmware and, based on that, will
 try to decide whether the bitstream buffer contained more than one
 frame. If the size of the buffer is larger than the consumed stream, it
 assumes that there are more frames in the buffer and that the buffer
 should be resubmitted for decode. This rarely works though and actually
 introduces problems, because:

 - v7 firmware will always return consumed stream size equal to whatever
 the driver passed to it when running decode (which is the size of the
 whole buffer), which means we will never try to resubmit, because the
 firmware will always tell us that it consumed all the data we passed to
 it;

 - v6 firmware will return the number of consumed bytes, but will not
 include the padding (stuffing) bytes that are allowed after the frame
 in VP8. Since there is no way of figuring out how many of those bytes
 follow the frame without getting the frame size from IVF headers (or
 somewhere else, but not from the stream itself), the driver tries to
 guess that padding size is not larger than 4 bytes, which is not always
 true;

 The only way to make it work is to queue only one frame per buffer from
 userspace and the check in the kernel is useless and wrong for VP8.
 MPEG4 still seems to require it, so keep it only for that format.

 I expressed my doubts to this patch in my previous email.
 I think that packed PB can also be found in other codecs such as H263.
 So please change to the following if this is a workaround for VP8 only.
 (The title says that it only changes behavior of VP8 decoding, so it is
 misleading).
 

Yes it is seen as affecting only VP8 decoding.

 - if (ctx-codec_mode != S5P_MFC_CODEC_H264_DEC 
 + if (ctx-codec_mode != S5P_MFC_CODEC_H264_DEC 
 + ctx-codec_mode != S5P_MFC_CODEC_VP8_DEC 
 

Ok. I will change it this way.

 
 Did you try to revert your patch https://patchwork.linuxtv.org/patch/15448/
 and checking if this fixes the problem for VP8?
 

I am afraid it will not solve the VP8 issue as before that patch, it
used to check for ctx-codec_mode != S5P_MFC_CODEC_H264_DEC and frame
type is S5P_FIMV_DECODE_FRAME_P_FRAME, buffer was sent again to decode.
This condition can be triggered in VP8 case causing erroneous behaviour.

So I will make the change as you suggested above.

Arun

 Latest MFC v6 firmware requires tile mode and loop filter setting to be
 done as part of Init buffer command, in sync with v7. Since there are
 two versions of v6 firmware with different interfaces, it is
 differenciated using the version number read back from firmware which
 is a hexadecimal value based on the firmware date.
 
 MFC version has two parts major and minor. Are you sure that date is 
 the only way to check if the interface has changed? Maybe the major number
 should stay the same (6) in this case, and the minor should be updates?
 Do you have contact with persons writing the firmware?
 

Yes I contacted with the firmware team and there is no difference in the
minor number too. Both the versions will read as MFC v6.5. Only
difference is the firmware date.

 Also, I don't see a patch with the newer firmware posted to linux-firmware.
 When it is going to be sent?
 

I will send it along with the v7 firmware.

Arun

 The patch adds IOMMU support for MFC driver.

 I've been working on an IOMMU driver lately, which led me to think
 about how drivers should be interfaced with IOMMUs. Runtime IOMMU
 handling is performed by the DMA mapping API, but in many cases
 (including Exynos platforms) the
 arm_iommu_create_mapping() and arm_iommu_attach_device() functions
 still need to be called explicitly by drivers, which doesn't seem a
 very good idea to me.
 Ideally IOMMU usage should be completely transparent for bus master
 drivers, without requiring any driver modification to use the IOMMU.

 What would you think about improving the Exynos IOMMU driver to
 create
 the mapping and attach the device instead of having to modify all bus
 master drivers ? See the ipmmu_add_device() function in
 http://www.spinics.net/lists/linux-sh/msg30488.html for a possible
 implementation.


 Yes that would be a better solution. But as far as I know, exynos
 platforms has few more complications where multiple IOMMUs are present
 for single IP.
 The exynos iommu work is still under progress and KyonHo Cho will have
 some inputs / comments on this. This seems to me a valid usecase which
 can be considered for exynos iommu also.
 
 Arun, could you tell me how did you test this?

It is tested on the IOMMU patches sent by KyongHo Cho (v11 series)
 https://lkml.org/lkml/2014/3/14/9
I found it to work well with v12 too.

 I think that the MFC driver should not be modified to use iommu. Dma_mapping
 should be used. On Tizenorg there is a 3.10 kernel with an iommu driver that
 works with MFC without any patches to the MFC drvier.

This is as per the mainline IOMMU driver patches which are being
reviewed now. I could see the exynos DRM also using this kind of
approach and is already in mainline. Thats why I thought of sending this.

 
 I disagree to merging this patch, sorry. This should be done the correct way.
 

Ok. I agree we can wait till the merging of Samsung IOMMU. If it takes
care of making the mapping and attaching the device without the master
driver intervention, then we can skip this patch. But till now it is not
taken care in the patches which are under review for samsung IOMMU.

Arun

 NACK.

 Hi Arun,

 I think that this driver is getting too complicated now.

 First there are separate files for MFC versions, but in addition there are
 many
 IF_MFCVx in there.

 The intention of this patch is to actually get rid of IF_MFCVx
 conditionals wherever possible.


 I am curious how many additional lines it would take to
 add s5p_mfc_cmd_v8.* and s5p_mfc_opr_v8.*.

 I get the point that this approach may result in less lines added, but
 having a callback specific for version use register pointers specific for
 another version makes the code look unreadable and difficult to maintain.

 Could you please give an example of how this reduces readability?
 I personally feel this patch makes things much more readable (see below).

 On the other hand, if we continued without the current method, we
 would have to sprinkle
 IF_MFCVx macros all around actual functions/operations, instead of
 just containing this
 to the regs structure, and the only difference in each path would be
 register name defines.
 I don't feel this would be a better direction to be honest.

 Compare, new, after this patch:

 + WRITEL(y_addr, mfc_regs-e_source_first_plane_addr);
 + WRITEL(c_addr, mfc_regs-e_source_second_plane_addr);

 vs previously, before this patch:

 - if (IS_MFCV7(dev)) {
 - WRITEL(y_addr, S5P_FIMV_E_SOURCE_FIRST_ADDR_V7);
 - WRITEL(c_addr, S5P_FIMV_E_SOURCE_SECOND_ADDR_V7);
 - } else {
 - WRITEL(y_addr, S5P_FIMV_E_SOURCE_LUMA_ADDR_V6);
 - WRITEL(c_addr, S5P_FIMV_E_SOURCE_CHROMA_ADDR_V6);
 - }

 And of course adding V8 more would make it even worse with yet another
 else if case.


 Please give your opinion on another way to add support for v8.
 s5p_mfc_cmd_v8.* and s5p_mfc_opr_v8.* ?

 If we add v7 and v8 files, a majority of their code will look like this:

 s5p_mfc_opr_v6.c:
 (...)
 void foo_v6(args)
 {
 foofun(REGISTER_A_V6);
 barfun(REGISTER_B_V6);
 }
 (...)

 s5p_mfc_opr_v7.c:
 (...)
 void foo_v7(args)
 {
 foofun(REGISTER_A_V7);
 barfun(REGISTER_B_V7);
 }
 (...)

 s5p_mfc_opr_v8.c:
 (...)
 void foo_v8(args)
 {
 foofun(REGISTER_A_V8);
 barfun(REGISTER_B_V8);
 }
 (...)

 I'm not sure this is less error prone and less code...


 Adding on to this, I had a discussion with the firmware team and what I
 got to know is future firmwares are also going to keep the operation
 sequence same as v6, but there can be more changes in register offsets
 as they accomodate more features. So if we go with opr_v8.c, we _might_
 need opr_v9.c also with hardly any change in the code except register
 offset modifications.
 
 If register offsets make for most of the differences between particular 
 MFC versions, then probably having the register pointers used instead of 
 base + OFFSET could be useful. Unfortunately we don't have much 
 information about the newer variants, so it's hard to say.
 
 Btw. I wonder why the firmware team couldn't simply add new registers at 
 the end of the address space, without breaking software compatibility 
 with every new version, even though rest of programming model mostly 
 stays intact, which is a pure nonsense. Couldn't you complain to the for 
 this if you have contact with them? Otherwise this madness will never stop.
 

I had a detailed discussion with the firmware team regarding this and
updated them the concerns. The need to do it is because, the register
offsets are grouped codec-wise. Like
0x000a H264
0x000d MPEG4
0x000f VP8
etc.

There are some holes given for future register additions also, but
sometimes many additional features are added to specific codecs and also
in the common feature set which doesnt fit in the pre-defined holes. So
as per them, the re-shuffle of registers was done in v8 so as to make it
more clean and taking into consideration future feature requirements.
But again it might have few changes here and there in the next version.
Since these register offsets are not really in our control, this
approach is best in the driver to absorb these changes without many if -
else conditions. The firware team assured me that they will try to avoid
these kind of changes as much as possible in future.

Arun

[PATCH] [media] s5p-mfc: Dequeue sequence header after STREAMON

2014-05-07 Thread Arun Kumar K
MFCv6 encoder needs specific minimum number of buffers to
be queued in the CAPTURE plane. This minimum number will
be known only when the sequence header is generated.
So we used to allow STREAMON on the CAPTURE plane only after
sequence header is generated and checked with the minimum
buffer requirement.

But this causes a problem that we call a vb2_buffer_done
for the sequence header buffer before doing a STREAON on the
CAPTURE plane. This used to still work fine until this patch
was merged b3379c6201bb3555298cdbf0aa004af260f2a6a4.

This problem should also come in earlier MFC firmware versions
if the application calls STREAMON on CAPTURE with some delay
after doing STREAMON on OUTPUT.

So this patch keeps the header buffer until the other frame
buffers are ready and dequeues it just before the first frame
is ready.

 This needs to be done differently. The problem is that you really have 
 multiple
 events that you want to subscribe to: one for each pad (or input: see the 
 way
 VIDIOC_G/S_EDID maps pad to an input or output index when used with a video 
 node,
 we have to support that for this event as well).

 What you want to do is similar to what is done for control events: there 
 you can
 subscribe for a specific control and get notified when that control changes.

 The way that works in the event code is that the 'id' field in the 
 v4l2_event
 struct contains that control ID, or, in this case, the pad/input/output 
 index.


 As I am new to v4l2-events itself, I might have some noob questions.
 I understood filling pad index into id field. But for video nodes,
 the application is supposed to put v4l2_buf_type in the id field?

 No, a capture video node can have multiple inputs (those are enumerated with
 VIDIOC_ENUMINPUTS), and each input can generate a SOURCE_CHANGE event, even 
 if it
 is not the currently active input. Hence the need of setting id to the input
 index. v4l2_buf_type makes no sense here.


Ok. But in a simple m2m device like mfc, the userspace has to subscribe to
the event say on the CAPTURE plane where buffers has to be re-allocated on
resolution change. So in such a case, what should be put in id field?


 In the application you will subscribe to the SOURCE_CHANGE event for a 
 specific
 pad/input/output index.

 In other words, the pad_num field should be dropped and the id field used
 instead.

 Assuming we will also add a 'changes' field (see my reply to the other post
 on that topic), then you should also provide replace

 This event indicates that the decoder has reached a point in the stream,
 at which the resolution changes. The userspace is expected to provide a new
 set of CAPTURE buffers for the new format before decoding can continue.
 The event can also be used for more generic events involving resolution
 or format changes at runtime for all kinds of video devices.

 Assuming we will also add a 'changes' field (see my reply to the other post

 v4l2-ctrls.c). That way it is sufficient to use just one element when calling
 v4l2_event_subscribe(): you will never loose information since if multiple
 events arrive before the application can dequeue them, the 'changes' 
 information
 will be the ORed value of all those intermediate events.
 

If I understand correctly, the implementation should go somewhat in the
following lines:

v4l2_event *new)

 Yes it is a superset.
 So the last patch in this series renames IS_MFCV7 to IS_MFCV7_PLUS.

 Shouldn't that be done first in that case?


Adding variants to access MFC registers patch actually removes lot of
such IS_MFCV7 checks from opr_v6.c file. Thats why I put that patch as the
last in the series to have minimal changes as possible.

[PATCH 0/3] Add MFCv8 support

2014-04-23 Thread Arun Kumar K
This patchset adds MFCv8 support to the s5p-mfc driver.
MFCv8 has the same operation sequence as that of v6+, but
there is some shuffling of the registers happened. So to
re-use the exisiting code, register access uses context
variables instead of macros.
The patchset modifies opr_v6 file to use register variables
and is tested on mfc v6, v7 and v8 based boards.

The patchset is based on the following set of patches
posted for MFC which are currently under review:

[media] s5p-mfc: Add support for resolution change event
v4l: Add resolution change event.
[media] s5p-mfc: Don't allocate codec buffers on STREAMON.
[media] s5p-mfc: Extract open/close MFC instance commands.
[media] s5p-mfc: Fixes for decode REQBUFS.
[media] s5p-mfc: Copy timestamps only when a frame is produced.
[media] s5p-mfc: add init buffer cmd to MFCV6
[media] s5p-mfc: Don't try to resubmit VP8 bitstream buffer for decode.
[media] s5p-mfc: Add a control for IVF format for VP8 encoder

Arun Kumar K (1):
  [media] s5p-mfc: Rename IS_MFCV7 macro

 Hi Arun,

 The patch adds IOMMU support for MFC driver.

 I've been working on an IOMMU driver lately, which led me to think about how
 drivers should be interfaced with IOMMUs. Runtime IOMMU handling is performed
 by the DMA mapping API, but in many cases (including Exynos platforms) the
 arm_iommu_create_mapping() and arm_iommu_attach_device() functions still need
 to be called explicitly by drivers, which doesn't seem a very good idea to me.
 Ideally IOMMU usage should be completely transparent for bus master drivers,
 without requiring any driver modification to use the IOMMU.

 What would you think about improving the Exynos IOMMU driver to create the
 mapping and attach the device instead of having to modify all bus master
 drivers ? See the ipmmu_add_device() function in
 http://www.spinics.net/lists/linux-sh/msg30488.html for a possible
 implementation.


Yes that would be a better solution. But as far as I know, exynos platforms has
few more complications where multiple IOMMUs are present for single IP.
The exynos iommu work is still under progress and KyonHo Cho will have
some inputs / comments on this. This seems to me a valid usecase which can
be considered for exynos iommu also.

Regards
Arun

From: Pawel Osciak posc...@chromium.org

This event indicates that the decoder has reached a point in the stream,
at which the resolution changes. The userspace is expected to provide a new
set of CAPTURE buffers for the new format before decoding can continue.
The event can also be used for more generic events involving resolution
or format changes at runtime for all kinds of video devices.

 This looks pretty good to me, but I'm a bit concerned about future
 compatibility. We might need to report more information to userspace, and in
 particular what has been changed at the source (resolution, format, ...). In
 order to do so, we'll need to add a flag field to v4l2_event_source_change.

Ok a flag can be added with bitfields for reporting specific event type.

 The next __u32 right after the source_change field must thus be zeroed. I see
 two ways of doing so:

 - zeroing the whole data array before setting event-specific data
 - adding a reserved must-be-zeroed field to v4l2_event_source_change

 I like the former better as it's more generic, but we then need to ensure that
 all drivers zero the whole data field correctly. Adding a new
 v4l2_event_init() function would help with that.


Is that a good idea to have an init() function just for zeroing the data field?
If this is agreed upon, I can add this, but it can be easily missed
out by drivers.
Also how about the drivers already using the v4l2_event. Should we
update those drivers too with v4l2_event_init() ?

[PATCH 1/2] v4l: Add resolution change event.

2014-04-16 Thread Arun Kumar K
From: Pawel Osciak posc...@chromium.org

This event indicates that the decoder has reached a point in the stream,
at which the resolution changes. The userspace is expected to provide a new
set of CAPTURE buffers for the new format before decoding can continue.

 Would it make sense to report the new resolution in the event data ? I 
 suppose
 it might not be available in all cases though. If we can't report it, would 
 it
 make sense to document how applications should proceed to retrieve it ?

 I wouldn't report that. We played with this in Cisco, and in the end you just
 want to know something changed and you can take it from there. Besides, what
 constitutes a 'resolution' change? If my HDMI input switches from 720p60 to
 720p30 the resolution stays the same, but I most definitely have to get the 
 new
 timings.

 So I would call the event something different: EVENT_SOURCE_CHANGE or 
 something
 like that.

 Getting the new timings is done through QUERYSTD or QUERY_DV_TIMINGS.


Ok will use the name V4L2_EVENT_SOURCE_CHANGE and update description
to reflect the generic usecase (not just for video decoders).

 A similar resolution change event might be useful on subdevs, in which case 
 we
 would need to add a pad number to the event data. We could possibly leave 
 that
 for later, but it would be worth considering the problem already.

 Actually, I would add that right away. That's some thing that the adv7604
 driver can implement right away: it has multiple inputs and it can detect
 when something is plugged in or unplugged.


Ok will add support for mentioning pad number in event data.

Regards
Arun

[PATCH] [media] s5p-mfc: Copy timestamps only when a frame is produced.

2014-03-18 Thread Arun Kumar K
From: Pawel Osciak posc...@chromium.org

Timestamps for destination buffers are assigned by copying them from
corresponding source buffers when the decode operation results in a frame
being outputted to a destination buffer. But the decision when to do this, i.e.
whether the decode operation on current source buffer produced a destination
frame, is wrongly based on display status. Display status reflects the status
of the destination buffer, not source.

This used to work for firmwares version = 6, because in addition to the above,
we'd check the decoded frame type register, which was set to skipped if
a destination frame was not produced, exiting early from
s5p_mfc_handle_frame_new().
Firmware =7 does not set the frame type register for frames that were not
decoded anymore though, which results in us wrongly overwriting timestamps of
previously decoded buffers (firmware reports the same destination buffer address
as previously decoded one if a frame wasn't decoded during current operation).

To do it properly, we should be basing our decision to copy the timestamp on the
status of the source buffer, i.e. decode status. The decode status register
values are confusing, because in its case display means a frame has been
outputted to a destination buffer. We should copy if decode and display
is returned in it. This also works on = v6 firmware, which behaves in the same
way with regards to decode status register.

[PATCH v2] [media] s5p-mfc: add init buffer cmd to MFCV6

2014-03-11 Thread Arun Kumar K
From: avnd kiran avnd.ki...@samsung.com

Latest MFC v6 firmware requires tile mode and loop filter
setting to be done as part of Init buffer command, in sync
with v7. Since there are two versions of v6 firmware with
different interfaces, it is differenciated using the version
number read back from firmware which is a hexadecimal value
based on the firmware date.

 From: Pawel Osciak posc...@chromium.org

 Currently, for formats that are not H264, MFC driver will check the
 consumed stream size returned by the firmware and, based on that, will
 try to decide whether the bitstream buffer contained more than one
 frame. If the size of the buffer is larger than the consumed stream, it
 assumes that there are more frames in the buffer and that the buffer
 should be resubmitted for decode. This rarely works though and actually
 introduces problems, because:

 - v7 firmware will always return consumed stream size equal to whatever
 the driver passed to it when running decode (which is the size of the
 whole buffer), which means we will never try to resubmit, because the
 firmware will always tell us that it consumed all the data we passed to
 it;

 This does sound like a hardware bug/feature. So in v7 the buffer is never
 resubmitted, yes? And this patch makes no difference for v7?


To give some background to this - I have added this patch [1] so that
multi-frame input buffer is supported by the driver.
[1] https://patchwork.linuxtv.org/patch/15448/

This patch was added to address one test case in VP8 decoding where
2 frames used to come in a single buffer. Without this patch, it used to
skip decoding of the 2nd frame even though firmware returned
consumed bytes as only 1 frame size.

Now this concept gave issues when we tried to decode the VP8 stream
encoded using v7 firmware. In that case, an arbitrary amount of padding
bytes were added by the firmware after every frame which is allowed as
per VP8 standard. While decoding this using v6, firmware returns less
consumed bytes than the input buffer, but the remaining bytes are just
padding. So firmware used to throw error if we re-submit this stuffing bytes
as a new frame. In v7 firmware, this problem doesnt exist as it consumes
(atleast indicates that it consumed) all the input buffer.

So we came to the conclusion that the testcase of giving multiple frames
in one input buffer itself was wrong and hence it was removed.
Now this concept is needed only for MPEG4 packed PB case which this
code for resubmitting input buffer was meant for (before my patch made
it generic).


 - v6 firmware will return the number of consumed bytes, but will not
 include the padding (stuffing) bytes that are allowed after the frame
 in VP8. Since there is no way of figuring out how many of those bytes
 follow the frame without getting the frame size from IVF headers (or
 somewhere else, but not from the stream itself), the driver tries to
 guess that padding size is not larger than 4 bytes, which is not always
 true;

 How about v5 of MFC? I need to do some additional testing, as I don't want
 to introduce any regressions. I remember that this check was a result of a
 fair amount of work and testing with v5.


I hope it wont give any issues in v5 also as it was never meant to handle
multiple frames in one input buffer.


 The only way to make it work is to queue only one frame per buffer from
 userspace and the check in the kernel is useless and wrong for VP8.
 MPEG4 still seems to require it, so keep it only for that format.

 Is your goal to give more than one frame in a single buffer and have the
 buffer resubmitted? Or the opposite - you are getting the frame resubmitted
 without the need? By the contents of this patch I guess the latter, on the
 other hand I do remember that at some point the idea was to be able to queue
 more than one frame per buffer. I don't remember exactly who was opting for
 the ability to queue more frames in a single buffer...


I hope now it is clear. We want to disallow multiple frames in one buffer as the
behavior is not consistent in v6 and its not allowed anyway from v7 onwards.

Arun

 The original code was for the initial version of v6 firmware.
 After that the v6 firmware has got many fixes and updates which also
 got updated in the products running the same.
 As such there are no official multiple versions of v6 firmware, but
 only fixes / updates to older version. I will update the s5p-mfc-v6.fw
 in the linux-firmware also with the newer version. Hope that will be
 fine.

 Unfortunately, I share the same concerns as Sylwester. We have two problems:
 1) new kernel + old firmware

 In this case, someone will update the kernel and find out that video
 decoding is not working. An assumption that I think is common, is that
 updating the kernel should not break anything. If it was working with the
 previous version it should work with the next.

 The solution I can suggest is that a check which firmware version is used
 has to be implemented. Maybe you can use the date of firmware to do this
 check?


Yes this concern is valid. I think its better to check for firmware date as the
old firmware is already submitted in mainline.

 2) old kernel + new firmware

 I see no clear solution to this problem. If the kernel is old and the
 firmware is behaving differently, the video decoding will not work. I can
 guess that this case would be less common, but still a person can update the
 firmware and leave the old kernel. Changing the firmware can be done by
 replacing a single file.

 In addition to the above, you need to clearly specify in the
 linux-firmware.git what is going on. A readme file is a must. Maybe a second
 v6 firmware file should be included?



Yes I can put the newer version of v6 firmware also in linux-firmware with a
readme detailing the difference between the same.
I hope this is a valid solution.

Arun

Re: [PATCH v10 1/2] [media] exynos5-is: Adds DT binding documentation

2014-02-03 Thread Arun Kumar K
Hi Mark,

This patch and hence a full series of 13 patches is waiting for a long time now
due to your missing ack on this DT binding patch.
I have addressed your review comments given on earlier version -
http://www.spinics.net/lists/devicetree/msg11550.html

Please check this and give an ack if it is fine to be merged.

Regards
Arun

 +Samsung EXYNOS5 SoC Camera Subsystem
 +
 +
 +The Exynos5 SoC Camera subsystem comprises of multiple sub-devices
 +represented by separate device tree nodes. Currently this includes: 
 FIMC-LITE,
 +MIPI CSIS and FIMC-IS.
 +
 +The sub-device nodes are referenced using phandles in the common 'camera' 
 node
 +which also includes common properties of the whole subsystem not really
 +specific to any single sub-device, like common camera port pins or the common
 +camera bus clocks.
 +
 +Common 'camera' node
 +
 +
 +Required properties:
 +
 +- compatible   : must be samsung,exynos5250-fimc
 +- clocks   : list of phandles and clock specifiers, corresponding
 + to entries in the clock-names property
 +- clock-names  : must contain sclk_bayer entry
 +- samsung,csis : list of phandles to the mipi-csis device nodes
 +- samsung,fimc-lite: list of phandles to the fimc-lite device nodes
 +- samsung,fimc-is  : phandle to the fimc-is device node
 +
 +The pinctrl bindings defined in ../pinctrl/pinctrl-bindings.txt must be used
 +to define a required pinctrl state named default.
 +
 +'parallel-ports' node
 +-
 +
 +This node should contain child 'port' nodes specifying active parallel video
 +input ports. It includes camera A, camera B and RGB bay inputs.
 +'reg' property in the port nodes specifies the input type:
 + 1 - parallel camport A
 + 2 - parallel camport B
 + 5 - RGB camera bay
 +
 +3, 4 are for MIPI CSI-2 bus and are already described in 
 samsung-mipi-csis.txt
 +
 +Required properties:
 +
 +For describing the input type in the child nodes, the following properties
 +have to be present in the parallel-ports node:
 +- #address-cells: Must be 1
 +- #size-cells: Must be 0
 +
 +Image sensor nodes
 +--
 +
 +The sensor device nodes should be added to their control bus controller (e.g.
 +I2C0) nodes and linked to a port node in the csis or the parallel-ports node,
 +using the common video interfaces bindings, defined in video-interfaces.txt.
 +
 +Example:
 +
 +   aliases {
 +   fimc-lite0 = fimc_lite_0
 +   };
 +
 +   /* Parallel bus IF sensor */
 +   i2c_0: i2c@1386 {

 +   reg = 0x3c;
 +   vddio-supply = ...;
 +
 +   clock-frequency = 2400;
 +   clocks = ...;
 +   clock-names = mclk;
 +
 +   port {
 +   s5k6aa_ep: endpoint {
 +   remote-endpoint = fimc0_ep;
 +   bus-width = 8;
 +   hsync-active = 0;
 +   vsync-active = 1;
 +   pclk-sample = 1;
 +   };

[PATCH] [media] exynos-gsc: swap cb/cr only for 3 plane formats

2013-12-20 Thread Arun Kumar K
From: Prathyush K prathyus...@samsung.com

The address for cb/cr needs to be swapped for 3 plane formats like
YVU420 and YVU420M. If these address gets swapped for other formats like
NV21, it results in passing a NULL dma address to gscalar (which will
result in a PAGE FAULT if sysmmu is enabled).

E.g. For NV21, the dma_address are (Y, CbCr, 0) and we swap them (Y, 0,
CbCr) which is incorrect.

[PATCH v10 2/2] [media] exynos5-is: Add media device driver for exynos5 SoCs camera subsystem

2013-12-12 Thread Arun Kumar K
From: Shaik Ameer Basha shaik.am...@samsung.com

This patch adds a top level media device driver for the Exynos5 SoC series
camera subsystem. The driver currently supports processing pipelines
involving following IP blocks:

* MIPI-CSIS
  MIPI CSI-2 bus front-end to the FIMC-LITE, image sensors with MIPI CSI-2
  bus should be linked with FIMC-LITE through this sub-device.

* FIMC-LITE
  Supports capture interface from device (Sensor, MIPI-CSIS) to memory.
  Supports interconnection (through internal data FIFO links) between
  devices like MIPI-CSIS and FIMC-IS.

* FIMC-IS
  Camera ISP with multiple image processing and peripheral devices like
  I2C or SPI bus controllers.

The G-Scaler IP is not yet supported.

The media device creates two kinds of pipelines for connecting the above
mentioned IP blocks.
The pipeline0 contains Sensor, MIPI-CSIS and FIMC-LITE devices and allows
to capture image data from external sensor to memory.
Pipeline1 uses FIMC-IS components for image processing operations on the
captured raw image data and provides scaled YUV image data at its output.

Pipeline0
 ++ +---+ +---+ ++
 | Sensor | -- | MIPI-CSIS | -- | FIMC-LITE | -- | Memory |
 ++ +---+ +---+ ++

Pipeline1
 ++ +-+ +---+ +---+
 | Memory | -- |   ISP   | -- |SCC| -- |SCP|

+Samsung EXYNOS5 SoC Camera Subsystem
+
+
+The Exynos5 SoC Camera subsystem comprises of multiple sub-devices
+represented by separate device tree nodes. Currently this includes: FIMC-LITE,
+MIPI CSIS and FIMC-IS.
+
+The sub-device nodes are referenced using phandles in the common 'camera' node
+which also includes common properties of the whole subsystem not really
+specific to any single sub-device, like common camera port pins or the common
+camera bus clocks.
+
+Common 'camera' node
+
+
+Required properties:
+
+- compatible   : must be samsung,exynos5250-fimc
+- clocks   : list of phandles and clock specifiers, corresponding
+ to entries in the clock-names property
+- clock-names  : must contain sclk_bayer entry
+- samsung,csis : list of phandles to the mipi-csis device nodes
+- samsung,fimc-lite: list of phandles to the fimc-lite device nodes
+- samsung,fimc-is  : phandle to the fimc-is device node
+
+The pinctrl bindings defined in ../pinctrl/pinctrl-bindings.txt must be used
+to define a required pinctrl state named default.
+
+'parallel-ports' node
+-
+
+This node should contain child 'port' nodes specifying active parallel video
+input ports. It includes camera A, camera B and RGB bay inputs.
+'reg' property in the port nodes specifies the input type:
+ 1 - parallel camport A
+ 2 - parallel camport B
+ 5 - RGB camera bay
+
+3, 4 are for MIPI CSI-2 bus and are already described in samsung-mipi-csis.txt
+
+Required properties:
+
+For describing the input type in the child nodes, the following properties
+have to be present in the parallel-ports node:
+- #address-cells: Must be 1
+- #size-cells: Must be 0
+
+Image sensor nodes
+--
+
+The sensor device nodes should be added to their control bus controller (e.g.
+I2C0) nodes and linked to a port node in the csis or the parallel-ports node,
+using the common video interfaces bindings, defined in video-interfaces.txt.
+
+Example:
+
+   aliases {
+   fimc-lite0 = fimc_lite_0
+   };
+
+   /* Parallel bus IF sensor */
+   i2c_0: i2c@1386 {
+   s5k6aa: sensor@3c {
+   compatible = samsung,s5k6aafx;
+   reg = 0x3c;
+   vddio-supply = ...;
+
+   clock-frequency = 2400;
+   clocks = ...;
+   clock-names = mclk;
+
+   port {
+   s5k6aa_ep: endpoint {
+   remote-endpoint = fimc0_ep;
+   bus-width = 8;
+   hsync-active = 0;
+   vsync-active = 1;
+   pclk-sample = 1;
+   };
+   };
+   };
+   };
+
+   /* MIPI CSI-2 bus IF sensor */
+   s5c73m3: sensor@1a {
+   compatible = samsung,s5c73m3;
+   reg = 0x1a;
+   vddio-supply = ...;
+
+   clock-frequency = 2400;
+   clocks = ...;
+   clock-names = mclk;
+
+   port {
+   s5c73m3_1: endpoint {
+   data-lanes = 1 2 3 4;
+   remote-endpoint = csis0_ep;
+   };
+   };
+   };
+
+   camera {
+   compatible = samsung,exynos5250-fimc;
+   #address-cells = 1;
+   #size-cells = 1;
+   status = okay;
+
+   pinctrl-names = default;
+   pinctrl-0 = cam_port_a_clk_active;
+
+   samsung,csis = csis_0, csis_1;
+   samsung,fimc-lite = fimc_lite_0, fimc_lite_1, 
fimc_lite_2;
+   samsung,fimc-is = fimc_is;
