[PATCH v2] drivers/media/platform/s5p-tv/sdo_drv.c: fix error return code
From: Peter Senna Tschudin peter.se...@gmail.com
Convert a nonnegative error return code to a negative one, as returned
elsewhere in the function.
A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)
// smpl
(
if@p1 (\(ret 0\|ret != 0\))
{ ... return ret; }
|
ret@p1 = 0
)
... when != ret = e1
when != ret
*if(...)
{
... when != ret = e2
when forall
return ret;
}
// /smpl

Each IR protocol decoder already checks whether it is enabled or not;
should it not be so that only allowed protocols can be enabled rather
than checking both enabled_protocols and allowed_protocols?
Just from reading store_protocols it looks like decoders which aren't
in allowed_protocols can be enabled, which makes no sense. Also
ir_raw_event_register all protocols are enabled rather than the
allowed ones.
Lastely I don't know why raw ir drivers should dictate which protocols
can be enabled. Would it not be better to remove it entirely?
I agree with you. I just thought that the only thing a decoder should care
is its decoding logic, but not including decoder management. My idaea is:
1) use enabled_protocols to select decoders in ir_raw.c, but not
placed in decoders to do the judgement.
2) remove allowed_protocols or just use it to set the default
decoder (also should rename allowed_protocols to default_protocol).
The default decoder should be the one set by the rc keymap.
I also have a question:
Is there a requirement that one more decoders are enabled for a
IR device at the same time?
Yes, you want to be able to multiple remotes on the IR device (which
you can do as long as the scancodes don't overlap, I think), and the
lirc device is implemented as a decoder, so you might want to see the
raw IR as well as have it decoded.
And if that will lead to a issue that each decoder may decode a
same pulse sequence to different evnets since their protocol is
different?
At the moment, no. David Hardeman has sent a patch for this:

Question: em28xx and audio inputs?
Hi all,
I've started work on fixing v4l2-compliance failures in em28xx and I came
across a broken ENUM/G/S_AUDIO implementation.
This is the current implementation:
static int vidioc_g_audio(struct file *file, void *priv, struct v4l2_audio *a)
{
struct em28xx_fh *fh= priv;
struct em28xx *dev = fh-dev;
if (!dev-audio_mode.has_audio)
return -EINVAL;
switch (a-index) {
case EM28XX_AMUX_VIDEO:
strcpy(a-name, Television);
break;
case EM28XX_AMUX_LINE_IN:
strcpy(a-name, Line In);
break;
case EM28XX_AMUX_VIDEO2:
strcpy(a-name, Television alt);
break;
case EM28XX_AMUX_PHONE:
strcpy(a-name, Phone);
break;
case EM28XX_AMUX_MIC:
strcpy(a-name, Mic);
break;
case EM28XX_AMUX_CD:
strcpy(a-name, CD);
break;
case EM28XX_AMUX_AUX:
strcpy(a-name, Aux);
break;
case EM28XX_AMUX_PCM_OUT:
strcpy(a-name, PCM);
break;
default:
return -EINVAL;
}
a-index = dev-ctl_ainput;
a-capability = V4L2_AUDCAP_STEREO;
return 0;
}
static int vidioc_s_audio(struct file *file, void *priv, const struct
v4l2_audio *a)
{
struct em28xx_fh *fh = priv;
struct em28xx *dev = fh-dev;
if (!dev-audio_mode.has_audio)
return -EINVAL;
if (a-index = MAX_EM28XX_INPUT)
return -EINVAL;
if (0 == INPUT(a-index)-type)
return -EINVAL;
dev-ctl_ainput = INPUT(a-index)-amux;
dev-ctl_aoutput = INPUT(a-index)-aout;
if (!dev-ctl_aoutput)
dev-ctl_aoutput = EM28XX_AOUT_MASTER;
return 0;
}
The g_audio implementation is wrong because it has a switch on a-index instead
of on dev-ctl_ainput. That's easy enough to fix, but s_audio is a real problem:
it interprets a-index as an input index instead of as an audio input index.
In addition, ctl_ainput does not have to be an EM28XX_AMUX_* index, as some
boards use an msp34xx instead.
I see a number of possible solutions:
1) Just delete the audio input support. Clearly nobody has used this code.
2) Don't implement audio input support if the msp3400 is used, otherwise
allow the user to set the em28xx AMUX to any of the possible values.
3) Don't implement audio input support if the msp3400 is used, otherwise
allow the user to set the em28xx AMUX to any of the values supported by
the list of inputs for that board.
The difference between 2 and 3 is that with 2 you can select e.g. a CD
input, even though it is unlikely that it is hooked up to something.
I have no idea whether that would make sense or not. I'm inclined to do
either 1 or 3.
Any em28xx that can shed some light on this?
Regards,
Hans

The linked order affect what drivers will be initialized first, when they're built-in at Kernel.

even though your ARM system might be little-endian by default, this
driver could possibly be used on machines with different endianness.
Something like this could be more optimal:
const u8 *ptr = fw-data + FW_REG_SIZE;
for (i = 1; i regs_num; i++) {
addr = le32_to_cpu(*(u32 *)ptr);
ptr += 4;
val = le16_to_cpu(*(u16 *)ptr);
ptr += FW_REG_SIZE;
Thanks for your advice. I will take le32(16)_to_cpu.

nit: break instead of goto ?
Ok, I will fix this.

pac7302-webcams and libv4lconvert interaction
Hi, I'm currently looking into the gspca_pac7302-driver and how it interacts with libv4lconvert. This is how it currently works - driver announces v4l2_pix_format 640x480 (width x height) - the frames (jpeg) passed to userspace are encoded as 480x640 and this complies with the jpeg-header we generate - libv4lconvert checks width/height in the jpeg-header and compares them with the image format announced by the kernel: a) values are the same: 1) V4LCONTROL_ROTATED_90_JPEG is NOT set for the device (standard case): = everything is fine, image is decoded 2) V4LCONTROL_ROTATED_90_JPEG is set for the device: = libv4lconvert bails out with -EIO displaying the error message unexpected width / height in JPEG header: expected: 640x480, header: 480x640 b) values are different: 1) V4LCONTROL_ROTATED_90_JPEG is NOT set: = libv4lconvert bails out with -EIO displaying the error message unexpected width / height in JPEG header: expected: 640x480, header: 480x640 2) V4LCONTROL_ROTATED_90_JPEG is set: = image is decoded and rotated correctly Thinking about this for some minutes: 1) shouldn't the kernel always announce the real image format (size) of the data it passes to userspace ? Current behavior seems inconsistent to me... Announcing the actual image size allows applications which trust the API value more than the value in the frame header to decode the image correctly without using libv4lconvert (although the image would still be rotated). 2) shouldn't libv4lconvert always rotate the image if V4LCONTROL_ROTATED_90_JPEG is set for a device ? It seems like a2) is a bug, because the expected size should be 640x480, too. 3) because all pac7302 devices are sending rotated image data, we should add them ALL to libv4lconvert. Currently only 4 of the 14 devices are on the list. Do you want me to send a patch ? What do you think ?

Using omap3-isp-live example application on beagleboard with DVI
Hello, My goal is to better understand how to write an application that makes use of the omap3isp and media controller frameworks and v4l2. I'm attempting to make use of Laurent's omap3-isp-live example application as a starting point and play with the AEC/WB capability. My problem is that when I start the live application, the display turns blue (it seems when the chromakey fill is done), but no video appears on the display. I do think that I'm getting good (or at least statistics) from the ISP because I can change the view in front of the camera (by putting my hand in front of the lens) and the gain settings change. root@beagleboard:~# live Device /dev/video6 opened: OMAP3 ISP resizer output (media). viewfinder configured for 2011 1024x768 AEWB: #win 10x7 start 16x74 size 256x256 inc 30x30 Device /dev/video7 opened: omap_vout (). 3 buffers requested.

Integrate camera interface of OMAP3530 in Angstrom Linux
Hello, I am using an embedded module called TAO-3530 from Technexion, which has an OMAP3530 processor. This processor has a camera interface, which is part of the ISP submodule. For an ongoing project I want to capture a video signal from this interface. After several days of excessive research I still don't know, how to access it. I configured the Angstrom kernel (2.6.32), so that the driver for OMAP 3 camera controller (and all other OMAP 3 related things) is integrated, but I don't see any new device nodes in the filesystem. I also found some rumors, that the Media Controller Framework or driver provides the device node /dev/media0, but I was not able to install it. I use OpenEmbedded, but I don't have a recipe for Media Controller. On the Angstrom website ( http://www.angstrom-distribution.org/repo/ ) there's actually a package called media-ctl, but due to the missing recipe, i can't install it. Can't say, I am an expert in OE. Can you help me point out, what's necessary to make the camera interface accessible?

I am looking forward for some idea on CEC. It is really complex in functionality. Maybe other guys is expecting simiar fruite from summit too. Yes, there will be a summit report. It's not quite finished yet, I think. With respect to CEC we had some useful discussions. It will have to be a new class of device (/dev/cecX), so the userspace API will be separate from drm or v4l. And the kernel will have to take care of the core CEC protocol w.r.t. control and discovery due to the HDMI 1.4a requirements. I plan on starting work on this within 1-2 weeks. My CEC presentation can be found here: http://hverkuil.home.xs4all.nl/presentations/v4l2-workshop-cec.odp Regards, Hans Thanks for quick response! It's good to know that CEC is independent with DRM/V4L for my HDMI implementation is FB/lcd-device based. CEC is also deserved to have independent management in both hardware signal and functionality. Someone also expressed similar thoughts before. Will remote control protocal parsing are done in userspace reference library? Or not decided yet? Are you referring to the remote control pass-through functionality? I don't know yet whether that will go through a userspace library or through the RC kernel subsystem, or possibly both. I mean all the feature that can involved in handhold remote control, one touch play, standby, on screen display, etc, such as play/pause/poweroff. I want to mention all non CDC features that can be implemented in user space. They are hard to be covered by any sub-system and user space library is more proper. Just like your metaphor, kitchen sink for CEC. I like your words. Yes, that will all be userspace. My plan is to have the CEC adapter driver handle the core CEC protocol, allow other drivers to intercept messages that are relevant for them and send messages themselves, and anything that remains will be available to userspace for which a new library will be created. Now, don't ask me about any of the details, since I don't have them yet :-) My plan is to start working on this next week or the week after. Are you willing to test early versions of this work? Can you test HDMI 1.4a features as well? Testing this might well be one of the harder things to do. I am willing to test or contribute to the library. But my hardware does not include HEAC. So my test scope limites to the features that can be implemented in user space.
