Interesting. cx88 also seems to have regressed.
Are you able to give a git commit range for what works & doesn't work?

I asked Adam to try building the modules with media-build
but have not heard anything further.

Date: Sat, 8 Sep 2018 20:49:22 -0400
From: Adam Stylinski 
To: linux-media@vger.kernel.org
Subject: 4.18 regression

Hello,

I haven't done a thorough bisection of kernel revisions, but moving from 
kernel 4.17.19
to 4.18.6 results in mythtv being unable to tune in any channel with a pic 
hdtv 5500
tuner (cx88 based device with an LG frontend). I get an error back from the 
channel
scanner about not being able to measure signal strength and getting back an 
error unknown
(errno 254).

I was able to use dvbtools with get-atsc to get a channel, but I don't 
think any of the
forward error correction was applied to it.

Let me know if you need more details.

Vince

I managed to get past the failure above with this change

   media: lirc: remove last remnants of lirc kapi

Glad you had some success.

I did some more rummaging in v4l-utils. It may help you to know about
dvb-fe-tool, which gives information about the frontend device
(eg /dev/dvb/adapter0/frontend0). In particular you can monitor the
s/n as you make changes:

 # dvb-fe-tool --femon -a 0  #here doing adapter0/frontend0

It displays info about the signal quality and the carrier/noise (C/N) ratio,
which might help any investigation of where the driver fails to cope as
you change what you are feeding it.

I noticed your dvbv5-scan showed C/N around 20dB but the manpage shows
'good signal' with C/N of 36dB which suggests the device should be
expected to deal with higher signal levels.

Once you figured out the signal level, did a dvbv5-scan work with no
errors? In the example you showed I saw the channels getting 'lock'
but then some kind of error occurred.

Regards
Vince

This looks like progress, now we can see more of the rather odd behaviour.

The tuned frequency does not progress monotonically,
but wanders up and down the band.

 19150   1434
 18450   -700
 17750   -700
 17784 34
 17716-68

The bandwidth and inversion type seem to be set correctly, at least.

Also:
 - every instance of if_frequency=0 pset_iffreq=
   shows the same numbers - zero. Surely that can't be right.
 - there seems to be no correlation at all between the AGC level
   (automatic gain control, I assume) and the 'cnr raw' which I'm
   guessing is some measure of the signal level.

I don't know where to start with decoding the rtl28xxu_ctrl_msg
I'm afraid. It's quite possible the remote control is active.
You can run
   ir-keytable -v
to show which remotes the system knows about.

We might get more clues to rub together from looking at where
scandvb falls over, if you run it under 'strace'
  strace -t -s 2048 -o ./scandvb.strace scandvb 
This will show the system calls being made. The -t will add timestamps
to the output that could be correlated with the dmesg output.

I'm curious - did you try scandvb with one of your other tuners?

I'm actually not familiar with scandvb, I can't find a program
with that name in the ubuntu repositories.
What I've used before is dvbv5-scan, which is part of:
 git://linuxtv.org/v4l-utils.git

That repo also includes the v4l2-compliance tool,
which might be useful here. Something like:
 ./v4l2-compliance -d /dev/dvb/adapter3 -a -T -v
What I am not sure about is whether the tuner needs to be
'zapped' to a nice strong TV channel before you can use this.

Anyway, hope some of these ideas are helpful.
Cheers
Vince

It's the right list. The problem is nobody seems to care.
I have one of these too, I was able to get it tune at one time
but there were some problems that I never ended up running down.

I was planning to dig it out and have a play with it again.

Just to confirm - you're building the media_build git tree on f26
and those drivers are the ones that are not working, yes?
If not, you need to try that to get any help here.
Have a look at https://git.linuxtv.org/media_build.git/about/
and let me know if you need further help with that.

It may be possible to get the driver into debug mode and get more
information logged. I'm not sure this will work but give it a go.

First set up the dynamic debug filesystem (may already be there)
# cat >> /etc/fstab
debugfs /sys/kernel/debug debugfs defaults 0 0
^D
# mount -av

Turn on debug printing for the modules of interest
# echo 'module rtl2832 +p' > /sys/kernel/debug/dynamic_debug/control
# echo 'module dvb_usb_rtl28xxu +p' > /sys/kernel/debug/dynamic_debug/control

Just to follow up on this.
The build still fell over during patching if I ran
   build --main-git --depth 1 -v 1
but did not if I ran
   build -v 1
(which causes the tarball to download instead)

This suggests an inconsistency between the two,
which is surprising and likely unintended.

I poked around a bit and found that the media subdir
was out of date and the build script was not updating it;
--depth 1 appears to suppress that.

Once I did a manual update, the patching succeeded.
I'll try to work out a patch so 'build' avoids this issue in future.

[patch] [media_build] Small fix to build script (resend)

Avoid going splat if --depth is not given

Commit 6b4a9c5 indroduced the --depth parameter to limit the commit history
pulled by when cloning, giving a nice speedup. But in the process it broke
running without the --depth parameter. The first invocation of
'./build --main-git' works fine, but the second falls over like so:

  fatal: No such remote or remote group: media_tree/master
  Can't update from the upstream tree at ./build line 430.

The fix is to check whether that remote has been defined before trying
to update from it.

There is a problem. make install has been broken for at least a week,
see the thread "media_build: fails to install"

The reason is that scripts/make_makefile.pl aborts

make[1]: Entering directory '/home/me/git/clones/media_build/v4l'
scripts/make_makefile.pl
Can't handle includes! In 
../linux/drivers/staging/media/atomisp/pci/atomisp2/css2400/Makefile at
scripts/  make_makefile.pl line 109,  line 4.

is because that css2400/Makefile includes another:

$ cat ../linux/drivers/staging/media/atomisp/pci/atomisp2/css2400/Makefile

ccflags-y += -DISP2400B0
ISP2400B0 := y

include $(srctree)/$(src)/../Makefile.common

The abort of scripts/make_makefile.pl means that the v4l/Makefile
does not get completely written out, in particular the rules for
making the 'media-install' target.

I am not sure how to fix this. The make_makefile.pl deliberately
falls over when given an include to deal with, so there must be
some other mechanism in the media_build framework that handles
this kind of thing. But I am not aware of it.

I can confirm this issue.

The reason is that scripts/make_makefile.pl aborts

make[1]: Entering directory '/home/me/git/clones/media_build/v4l'^M
scripts/make_makefile.pl^M  
Can't handle includes! In

[PATCH] Small fix to build script

2017-06-01 Thread Vincent McIntyre
Avoid going splat if --depth is not given

Commit 6b4a9c5 indroduced the --depth parameter to limit the commit history
pulled by when cloning, giving a nice speedup. But in the process it broke
running without the --depth parameter. The first invocation of
'./build --main-git' works fine, but the second falls over like so:

  fatal: No such remote or remote group: media_tree/master
  Can't update from the upstream tree at ./build line 430.

The fix is to check whether that remote has been defined before trying
to update from it.

[PATCH 0/3] Fix failure of media_build build script

2017-05-30 Thread Vincent McIntyre
Hi

I was trying to run build --main-git without the --depth option and
it went splat. The attached series fixes my problem, possibly not
entirely correctly for all cases, in the first patch. The other two
patches are small cleanups that should make things more legible.

Vincent McIntyre (3):
  Use a better name for the upstream remote.
  Add a helper to simplify all the system-or-die calls
  Convert remaining system-or-die calls

The attached log file has the failure. This build was done with a
fresh git clone.  I did a quick grep of the tree and the only place I
find cec_devnode_register is in the module that fails to build,
cec-core.c.

Any advice welcome.

This does not prevent you from building the v4l-dvb tree if you have the

If you are experiencing problems building the v4l-dvb tree, please try
building against a vanilla kernel before reporting a bug.

Vanilla kernels are available at http://kernel.org.
On most distros, this will compile a newly downloaded kernel:

Please see your distro's web site for instructions to build a new kernel.

Hi

I have been working with Sean on figuring out the protocol used by a
dvico remote.
I thought the patch he sent was at fault but I backed it out and tried again.

I've attached a full dmesg but the core of it is when dvb_usb_cxusb
tries to load:

Re: Failure of ./build

2017-02-04 Thread Vincent McIntyre
Hi Bill

with this patch I can get past the errors you are seeing. Those errors
are happening because recent changes in the mainline kernel have not
been reflected in the backport patches directory.

[Patch] remove unneeded pr_fmt patches

Recently  (bbdba43f) the pr_fmt macro was removed from ivtvfb.c, and
some lirc driver
files in staging were removed entirely (2933974c..f41003a23a). Update
pr_fmt.patch
to reflect those changes.

If it is a cross-distro breakage then probably the kernel bugzilla
might be the right place to file an issue. However you should first
spend a little time to clarify exactly where the issue is occurring.

First, can you find the usb-id or pci-id for the device, as well as
the marketing name. It's important for others to be able to identify
the device unambiguously. dmesg from a working kernel should show this.
Once you have that, run lspci -vvv or lsusb -v for that device and
save the output.

Next I suggest making a list of the kernels you have tried and whether
the device is working or not with that kernel. You want the most detailed
version number you can find, from the kernel package name or changelog.
The release date for the packages would probably be helpful too.

Then you should look for the latest working and earliest non-working
version. Since you are using distro kernels, which will have many
differences from the one published by kernel.org, it may be worth trying
to find the git repository and the git tag that matches the kernels on
either side of the break. This will allow easy diffing of the code.
The changelog for the kernel package should have dates and perhaps even
git commit ids that will help with that quest. If you get stuck on this
just post your results so far, someone may be able to help.

It might also be useful to capture dmesg logs for those two (working/
nonworking) versions so you can look for the place where things go awry.

Haven't been able to find anything suitable. I would order something
but I won't be able to follow up for several weeks.
I'll ask on the myth list to see if anyone is up for trying this.

I mostly figured this out but something weird happens with the most
significant bit (see my follow-on email). FWIW, this is on ubuntu 16.04
with their standard kernel (4.4) and a bog-standard US english layout.

It turned out that that I had to restart X to make it notice the updated keymap.
After that, the modfied keymap I set up is mostly working.

There is still a bit of a mystery. As I understand it, X should notice
key codes less than 255 (0xff). But it seems to be ignoring KEY_STOP
(code 128, 0x80) and any key codes higher than that but less than 255.
ir-keytable -t shows the right codes.

That's correct. ir-keytable seems to be doing the right thing, mapping
the scancode to the input-event-codes.h key code I asked it to.

The application I am trying to use it with is the mythtv frontend.  I
am doing the keycode munging from an SSH session while myth is still
running on the main screen. I didn't think this would matter (since it
worked for KEY_OK->KEY_ENTER) but perhaps it does. Obviously
ir-keytable -t intercepts the scancodes when it is running, but when I
kill it myth responds normally to some keys, but not all.



I wanted to mention that the IR protocol is still showing as unknown.
Is there anything that can be done to sort that out?

yep, works nicely.

Things are looking much better!
As shown below I am able to clear a keytable and put in a fresh one.

[patch] fix 'make install'

2016-11-23 Thread Vincent McIntyre
Recent work on handling the case of no frame_vector.c in the kernel
seems to have ended up breaking the 'make install' target. The patch
below makes it work again for me, on ubuntu 16.04 LTS, amd64,
kernel 4.4.
Without it, I get this behavior:
moake -C /home/me/media_build/v4l install
make[1]: Entering directory '/home/me/media_build/v4l'

Thanks for this. I have got it to build within the media_build setup
but will need to find some windows in the schedule for testing. More
in a couple of days. Are there specific things you would like me to
test?

I tried this with the rc1 device as a test. I get this odd result:

So I checked on the ir receivers and found the rc1 device ir receiver

So something is connecting via IR.

Ah. Here we have a problem. The device (/dev/input/event15)
doesn't have a corresponding rcX node, see ir-keytable output below.
I had it explained to me like this:

  A "HID" device is basically any input device that resembles
  a keyboard or mouse (Human Interface Device). The label may also cover
  things like joysticks, etc. It does /not/ include remotes, so it
  seems, since "remote" can cover a wide variety of input devices.

  Some remotes can emulate fully or partially keyboard keypresses
  which is why they can be treated as HID devices. Of course, not all
  the keys may be mapped correctly or at all.

I may have given bad information here - I need to check whether the
IR receivers for these devices are properly connected. That might be
why there was no response...

So are you saying that the hex codes in the rc_map_dvico_mce_table
struct are invalid (at least in some cases)?

How can I tell what protocol is in use?
0x00010001 doesn't mean much to me; I did search the linux source
for the code but didn't find any helpful matches.

Great idea. Do you mean something like [1]?
Or the (presumably generic) receiver that comes with [2]?
Would a FLIRC work?

Probably dumb question - in this machine I also have
an iMon Remote (152c:ffdc)
and Leadtek WinFast DTV Dongle Dual
Do you think either of those would be helpful?
I tried evtest with them and the remote, no responses.

ir-keytable: infinite loops, segfaults

2016-11-16 Thread Vincent McIntyre
Hi,

I have a fairly old dvico dual digital 4 tuner and remote.
There seem to be some issues with support for it, can I help fix them?

I am using ir-keytable 1.10.0-1 on Ubuntu 16.04 LTS,
with kernel 4.4.0-47-generic (package version 4.4.0-47-generic)

The remote's keymapping is the one in /lib/udev/rc_keymaps/dvico_mce;
kernel support for the device is in media/usb/dvb-usb/cxusb.c.

Mostly it works, in that I get correct keycodes back from evtest
and ir-keytable -t. But I want to change some of the keycode mappings
and that is not working.

  # cat >testfile
  0xfe47 KEY_PAUSE
  ^D
  
  # ir-keytable -v -d /dev/input/event15 -w testfile
  Parsing testfile keycode file
  parsing 0xfe47=KEY_PAUSE:   value=119
  Opening /dev/input/event15
  Input Protocol version: 0x00010001
  fe47=0077
  Wrote 1 keycode(s) to driver

So far so good, yes? But evtest still reports the same keycode
for the key I tried to modify.

  # evtest
  
  
  Event: time 1479206112.262746, type 1 (EV_KEY), code 164 (KEY_PLAYPAUSE), 
value 1
  Event: time 1479206112.262746, -- SYN_REPORT 
  Event: time 1479206112.262760, type 1 (EV_KEY), code 164 (KEY_PLAYPAUSE), 
value 0
  Event: time 1479206112.262760, -- SYN_REPORT 
 
  # irkeytable -r -d /dev/input/event15 |grep PAUSE
  Enabled protocols: unknown rc-5 sony nec sanyo mce-kbd rc-6 sharp xmp 
  scancode 0xfe02 = KEY_PAUSE (0x77)
  scancode 0xfe47 = KEY_PLAYPAUSE (0xa4)

I thought that I might need to clear and replace the entire table
to get things working. This is where the problems really start.

First trying to clear the table causes an infinite loop.

  # ir-keytable -d /dev/input/event15 -c
  Opening /dev/input/event15
  Input Protocol version: 0x00010001
  Deleting entry 1
  Deleting entry 2
  Deleting entry 3
  Deleting entry 4
  
  Deleting entry 2114689
  Deleting entry 2114690

Then I tried to load a modified version of dvico_mce
The whole file was there, with just this change:

[media] stk1160: Reduce driver verbosity

These messages are not really informational, and just makes the driver's
output too verbose. This commit changes some messages to a debug level,
removes a really useless driver loaded message and finally undefines
the DEBUG macro.

 In case it matters here, I have these cards and am using the driver
 built from
   git clone git://linuxtv.org/media_build.git
   git clone g...@github.com:jaredquinn/DVB-Realtek-RTL2832U.git
 
 I get rather reliable tuning with hardly any of the old problems of
 zero length recordings of fails to tune  some channels.
 
 I run old fedora 19 though, and things may have deteriorated since?
 Last time I needed to build was Jan 31 for kernel 3.14.27-100.fc19.x86_64.
 Is this driver included with the kernel these days?

Thanks for your reply Eyal.
There is certainly an in-kernel driver, which I am trying to use.
I don't know what relation it has to the github code, which looks
to have useful information on registers and other magic numbers
that might be needed for proper operation.

Antti, would you care to comment on whether the github code
linked above is useful at all for your work on the realtek drivers?

Cheers

issue with videobuf2-dma-sg.ko

2015-05-03 Thread Vincent McIntyre
Hi

I am trying to load the cx23885 module. It fails to load and I get this in 
dmesg;

  [  433.506983] videobuf2_dma_sg: Unknown symbol dma_buf_export (err 0)

I wrote a small script to load each of the dependencies one at a time,
which shows pretty clearly the problem is videobuf2-dma-sg.ko.

I am up to date with the media_tree:

 Try again, I've hopefully fixed this problem. You need to do a git pull from 
 the
 media_build.git repo and that should solve it.
 
 Let me know if you run into problems.
 

That was quick work!
I rebuilt and the module is loading fine again, dmesg attached.
Thanks Hans

I should add how I triggered this
 - build --main-git, make install, halt
 - cold-boot, check modules loaded ok, check /dev/dvb/adapter* exist
 - try to tune with dvb-apps 'scan' and adapter0/tuner0. This is where
the oops occurred.

 I've just updated media_build to stop compiling the smiapp driver for kernels
  3.20. So if you do 'git pull' in your media_build directory and try again
 it should work.

I can confirm that it does work now.
Thanks for the quick turnaround, much appreciated.

[patch] ensure correct install of modules from drivers/{misc,staging}

2014-09-14 Thread Vincent McIntyre
Hi,

On an ubuntu system the code builds ok but not all modules run properly;
the issue I noticed was the cx23885 module gave these errors when loaded:

[   20.395552] cx23885: disagrees about version of symbol altera_init
[   20.395560] cx23885: Unknown symbol altera_init (err -22)

The cause was that there were two altera-stapl modules in the /lib tree

% find .-type f -name altera_stapl.ko
 ./kernel/drivers/misc/altera-stapl/altera-stapl.ko
 ./kernel/drivers/linux/drivers/misc/altera-stapl/altera-stapl.ko

I traced that back to make_makefile.pl; it was not using the right
directory names for any drivers in drivers/misc or drivers/staging.
For example before the patch this line was being generated:

 n=0;for i in altera-stapl.ko;do if [ -f $i ]; then if [ $n -eq 0 ]; then 
echo -n ../linux/drivers/misc/altera-stapl/: ; install -d 
/lib/modules/3.13.0-35-generic/kernel/drivers/media/../linux/drivers/misc/altera-stapl;
 fi; n=$(($n+1)); if [  $n -eq 4 ]; then echo; echo -n   ; n=1; 
fi; echo -n $i ; install -m 644 -c $i 
/lib/modules/3.13.0-35-generic/kernel/drivers/media/../linux/drivers/misc/altera-stapl;
 fi; done; if [  $n -ne 0 ]; then echo; strip --strip-debug 
/lib/modules/3.13.0-35-generic/kernel/drivers/media/../linux/drivers/misc/altera-stapl/*.ko;
 fi;


after applying this patch the same line is:

 n=0;for i in altera-stapl.ko;do if [ -f $i ]; then if [ $n -eq 0 ]; then 
echo -n ../misc/altera-stapl/: ; install -d 
/lib/modules/3.13.0-35-generic/kernel/drivers/media/../misc/altera-stapl; fi; 
n=$(($n+1)); if [  $n -eq 4 ]; then echo; echo -n   ; n=1; fi; echo 
-n $i ; install -m 644 -c $i 
/lib/modules/3.13.0-35-generic/kernel/drivers/media/../misc/altera-stapl; fi; 
done; if [  $n -ne 0 ]; then echo; strip --strip-debug 
/lib/modules/3.13.0-35-generic/kernel/drivers/media/../misc/altera-stapl/*.ko; 
fi;

This also affects drivers in staging.

The patch is below.

[patch] ensure correct install of modules from drivers/{misc,staging}

v4l/scripts/make_mediafile.pl uses the %instdir hash to collate a list
of directories in media_build/linux which contain Makefiles; it uses
this data when constructing a dependency for the Makefile.media target.
It also uses this hash to collate all the individual module names and
generate code which installs the individual modules.
But it gets the installation directory wrong in the case of modules
outside the linux/drivers/media tree.

To fix, do the collation of source locations and conversion into install
locations as separate steps.

 Next time, please add the logs directly at the email, as this makes

Ok. I wanted to ensure it did not get mangled into unreadability
by the journey through various email systems.

 Anyway, based on this:
 
 [   16.332247] xc2028 0-0061: Loading firmware for type=BASE F8MHZ (3), id 
 .
 [   16.344378] cxusb: i2c wr: len=64 is too big!
 
 I suspect that the enclosed patch should fix your issue. Please test. If it
 works, please reply to this email with:
   Tested-by: your name your@email
 

The patch is working for me. My tested-by is inline below.
Test procedure:
- git checkout git://linuxtv.org/media_build.git
- cd media_build
- ./build --main-git
- grep define MAX_XFER_SIZE media/drivers/media/usb/dvb-usb/cxusb.c
#define MAX_XFER_SIZE  64
- vi media/drivers/media/usb/dvb-usb/cxusb.c
- grep define MAX_XFER_SIZE media/drivers/media/usb/dvb-usb/cxusb.c
#define MAX_XFER_SIZE  80
- cd media; make -C ../v4l; cd ..
- sudo make install
- sudo halt
- (after boot) dmesg
- try to tune one of the receivers - works ok

 id .
   [   16.344378] cxusb: i2c wr: len=64 is too big!
 
 64 bytes is too short for firmware load on this device. So, increase it
 to 80 bytes.

[bug]? cx23885 - tries to create duplicate (firmware) filename in sysfs

2011-06-06 Thread Vincent McIntyre
Hi,

I just noticed this starting to happen - I can't see any sign of it in syslog
before I rebuilt the modules (git commit tags are listed below).
I don't know if this is a backporting issue or a bug in mainline.

The system in question has two dual-tuner cards, one a USB (mounted on
a PCI card)
the other a PCI card. Both use the cx23885 driver. As far as I can see
the PCI card is
where the problem lies - there's no way to distinguish between the two
tuners (I found
this when trying to write some udev rules to generate stably-named symlinks).

Re: imon: spews to dmesg

2011-05-17 Thread Vincent McIntyre
I think I have found the source of this.

linux/drivers/media/video/omap3isp/Makefile  contains this:
 ifdef CONFIG_VIDEO_OMAP3_DEBUG
 EXTRA_CFLAGS += -DDEBUG
 endif

but this module is not turned on,nor is the _DEBUG setting for it.
 % grep OMAP3 media_build/v4l/.config
 # CONFIG_VIDEO_OMAP3_DEBUG is not set
 # CONFIG_VIDEO_OMAP3 is not set
 % grep OMAP3 media_build/v4l/.myconfig
 CONFIG_VIDEO_OMAP3_DEBUG := n
 CONFIG_VIDEO_OMAP3   := n

nonetheless:
 % grep DDEBUG media_build/v4l/.imon.o.cmd
...
-fconserve-stack -Idrivers/media/dvb/dvb-core
-Idrivers/media/dvb/dvb-usb -Idrivers/media/dvb/frontends
-Idrivers/media/dvb/dvb-core -Idrivers/media/video
-Idrivers/media/common/tuners -Idrivers/media/dvb/dvb-core
-Idrivers/media/dvb/frontends -Idrivers/media/video
-Idrivers/media/common/tuners -Idrivers/media/dvb/dvb-core
-Idrivers/media/dvb/frontends -DDEBUG -Isound
-Idrivers/staging/cxd2099/ -g
...

Commenting out the three lines above in the omap3isp/Makefile gets rid
of the -DDEBUG
in the .cmd files. It seems to be the only Makefile that sets -DDEBUG
in this way.
Not sure what the real remedy is here.

v4l/config-compat.h had the expected extra #define in it and the build

Re: imon: spews to dmesg

2011-04-30 Thread Vincent McIntyre
On 4/20/11, Jarod Wilson ja...@wilsonet.com wrote:


 Those are almost all dev_dbg spew.

Indeed, it seems to come from

retval = send_packet(ictx);
if (retval) {
pr_err(send packet failed!\n);
goto exit;
} else {
dev_dbg(ictx-dev, %s: write %d bytes to LCD\n,
__func__, (int) n_bytes);
}

in imon.c


 The normal way to enable dev_dbg spew is via some debugfs magic:

 http://outer-rim.gnu4u.org/?p=38

 (see also kernel source/Documentation/dynamic-debug-howto.txt)


I don't quite see why this would have happened since I didn't have a
debugfs mounted
during the build or after rebooting to use the new modules, to the
best of my knowledge.

 But I also seem to recall that DEBUG may be getting defined
 somewhere as part of the media_build process, which might be what
 is enabling that spew in your case.

I can't follow the flow in the build system well enough to see for
sure where this would be enabled or not, but some after grepping I
found the following in the file
 /linux/drivers/media/dvb/ttusb-budget/dvb-ttusb-budget.c
 136-
 137:#define DEBUG 0
 138-static int ttusb_cmd(struct ttusb *ttusb,

All other uses of DEBUG that I can find are #if'ed or #ifdef'ed in the
C code files.

dvb-ttusb-budget.c is being built, but why should the definition there
affect other modules?

imon: spews to dmesg

2011-04-18 Thread Vincent McIntyre
Hi list,

I just (2011-04-19) upgraded to the current media_build with build.sh
 commit bcfdefe9f4538abf12fca1cdb631c80e3d598026
 Author: Mauro Carvalho Chehab mchehab@nehalem.(none)
 Date:   Sun Apr 17 08:21:25 2011 -0300
and hit a problem.

I have an Antec case with an LCD screen. It needs the imon driver.
The LCD screen has been working well using media_build from 2011-01-30.

The imon kernel module now spews this at a high rate:
[   38.532581] imon 9-1:1.0: lcd_write: write 8 bytes to LCD
[   38.544545] imon 9-1:1.0: lcd_write: write 8 bytes to LCD

[   38.652034] imon 9-1:1.0: lcd_write: write 8 bytes to LCD

If I stop LCDd
 # /etc/init.d/LCDd stop
the spew stops.

and what should I do to fix it ?

Hi Nick,

Could you post the output of
  lspci -vvv -nn
for the device in question - you'll also need to give the -s argument,
eg -s 02:00.0
or whatever.

This is so it is clear what chips your example of the card is using -
a given card may be implemented with different chipsets over time
depending on how organised the manufacturer is.

Some kernel output similar to that shown on the wiki page, showing
what happens at boot time, may be useful as well.

I have this card, and it is working reasonably well with recent
media_build code:

I do. I haven't tested very carefully that I can use both tuners at
once successfully but I am pretty sure there have been times when both
have been running. I only use them with mythtv,
unless I am testing something like new v4l modules and in that case I
just use one tuner at a time.

The box has two tuner cards, and this one is usually the second one in
the enumeration.

media_build: build fails against (ubuntu) 2.6.32 on pvrusb2-debugifc.c

2011-01-19 Thread Vincent McIntyre
Hi,

I am building against linux-2.6.32-26-generic from ubuntu, with just
the linux-headers package.

I know there is a big fat warning about doing this but I thought I
should report the issue
because mostly building like this does work.

The build was against a clean checkout of the media_build tree, using build.sh.

The build fails with:

Thanks for your explanation. I was quite puzzled for some time why I

 The code now compiles for me but I don't know if it will actually
 work, I don't have the hardware.

 Ok, I did the above procedure, adding your patch to the diff. Please test.


That bit works now (from git, the tarball downloaded by build.sh
hasn't caught up).
Thanks for applying.

However the build now fails on a separate issue, which I'll put in a new thread.

I was mainly intending to show how I happen to do this. It's way too complicated

 It would be nice to have some optional parameters there, to make life easier
 for end-users.

I can certainly try to supply some patches but I'm not sure what

build.sh is such a nice simple method; my script attempts to do
everything via git which is
overkill unless one is actively developing. Perhaps I could rework
into a distinct build_git.sh.

 It's unclear that adding this would cause a lot of extra work; the
 patches that need to be applied are quite few - a tribute to the
 design work!

 That's weird. Here, it compiles fine against my 2.6.32 kernel, as there's a
 patch that removes the extra parameter. I'll double check and add a fix
 if I found something wrong.

I think a couple of modules may have been missed;

  cx88-input.c
  hdpvr-i2c.c

I get the same result whether building from a git clone of media-tree
or via media_build/build.sh.

I am building against ubuntu 2.6.32-26-generic aka 2.6.32.24+drm33.11, on i386.
I am using just their kernel-headers package for the build. Usually it works ok.

Re: difference mchehab/new_build.git to media_build.git ?

2011-01-08 Thread Vincent McIntyre
 There's no difference. It started out at mchehab/new_build.git, then got
 moved
 to media_build.git, but there's a symlink in place to keep from breaking
 things
 for people who originally checked it out at the old location.

 The move essentially promoted it from something Mauro's tinkering with to
 something generally useful for a wider audience. And its also being worked
 on
 by more people than just Mauro now (myself included).

Thanks for clarifying this. Doesn't this justify a one-line NEWS item?
I can understand not wanting to mention it while still experimental, but now...

[patch] new_build.git - avoid failing on 'rm' of nonexistent file

2011-01-07 Thread Vincent McIntyre
While attempting to build recently I have found the 'make distclean'
target fails if 'rm' tries to remove a file that is not there. The
attached patch fixes the issue for me (by using rm -f).
I converted all the other 'rm' calls to 'rm -f' along the way.

Please consider applying this.

I do have to say CONFIG_DVB_FIREDTV=n, it appears still to be a
problem on ubuntu.

 First dumb question - (I'll try to minimise these)

...
 The patches generally reverse-apply some upstream change. Andy's approach
 could be done via compat.h. I opted to just backport the upstream patch.

 Anyway, there were other problems on it, due to other API changes, and to
 the move of the rc-core from .../IR to .../rc directory.

 I opted to simplify the backports, avoiding to duplicate the same patch on
 several different directories.


I see that now, after some quality time in the backports directory. It
does look simpler.

I think my original problem was that somehow the patch in the
2.6.32_series to remove references to noop_llseek() was not applying
cleanly. No idea why, I flushed the logs I kept.

Thanks all, I'll give the new build a test run as soon as I get a chance.

 Shouldn't you be building from:

 for backward compat builds? (I'm not sure myself.)

Yes, I am using this as described in the README (make tar DIR=foo;
make untar; make).

 noop_llseek() is a newer kernl function that provided a trivial llseek()
 implmenetation for drivers that don't support llseek() but still want to
 provide a successful return code:

 http://lkml.org/lkml/2010/4/9/193
 http://lkml.org/lkml/2010/4/9/184

Thanks for explaining this.

 Is it that an additional backport patch may be needed here?

 Yup.  It looks like you need something.  You'll need a patch to
 implement the trivial noop_llseek() function available in the links
 above.

This is helpful, indeed.

First dumb question - (I'll try to minimise these)

 * Inspection of the patches new_build/backports shows all the patches
are to things in the v4l/ tree
 * Yet the patch you pointed to is to fs/read_write.c and include/linux/fs.h

So my question: should this function be implemented as a patch to
files outside the v4l/ tree
or as additional .c and .h files within the v4l top level. I guess the
latter would then need to be #included in a bunch of v4l files. I'm
mainly unsure of the convention here.

I checked the mkrufky tree mentioned in README.patches but that didn't help.
I also checked the mercurial tree and could not find any backport of
noop_llseek,
but I may have missed something.

The consumers of the function appear to be:
$ find v4l -exec grep -li noop_llseek {} \;

Is it that an additional backport patch may be needed here?

The kernel I am running here is Ubuntu 2.6.32-25.43-generic (2.6.32.21+drm33.7)
with one tiny patch, reverting a bad change to drivers/usb/serial/ftdi_sio.c.

Any advice appreciated.

[patch] new_build.git - remove bashist equality testing

2010-10-30 Thread Vincent McIntyre
Hi,

while trying to build this on ubuntu 10.04 (2.6.32-24-generic) I
noticed some of the equality
tests in linux/Makefile are bash-style, not POSIX-style.
The problem I encountered was error messages like:
  ...
  make -C ../linux apply_patches
  make[2]: Entering directory `/home/ltv/git/clones/linuxtv.org/new_build/linux'
  [: 23: v2.6.32: unexpected operator
  cat: .patches_applied: No such file or directory
  [: 23: unexpected operator

Please consider applying the attached patch, which fixes the problem for me.

Cheers
Vince

Re: Reception issue: DViCO Fusion HDTV DVB-T Dual Express

2010-07-14 Thread Vincent McIntyre
I have this card (lspci reports pciid 14f1:8852, subsystem 18ac:db78)
and the Dual Digital 4 (lsusb 0fe9:db78).
I had a few problems similar to this (on Nine in Sydney, particularly)
until Mauro applied
some patches to fix some weirdness in the calculations of the tuning
offsets, a few months ago now. Now they are running reliably. I don't
know if the patches have made it into
mainstream distro kernels yet, but you should have them if you are
building the dvb drivers from the mercurial tree against the kernel
you have.

You may want to try dvbsnoop (http://www.linuxtv.org/wiki/index.php/Dvbsnoop)
to check on the mpeg streams. I haven't used it myself...

See also http://www.linuxtv.org/wiki/index.php/Testing_reception_quality
and http://www.linuxtv.org/wiki/index.php/Testing_your_DVB_device.

It may also help to load the driver module with the 'debug' option on.

I've found VLC useful for testing reception quality by eye,
though it's not obvious how to force usage of a particular tuner.
I am pretty sure it can record.

Also '{c,s,t}zap' ow w-zap are helpful for quick tests of basic 
functionality like tuning, and with the signaltest.pl script

( http://linuxtv.org/wiki/index.php/Testing_reception_quality)

I use MythTV in 'production' but I find it a bit clumsy for testing with.

Re: [RESEND] Re: DViCO FusionHDTV DVB-T Dual Digital 4 (rev 1) tuning regression

2009-12-08 Thread Vincent McIntyre
 Mauro,

 Resend of my proposed patch attached that reverts tuning regressions with
 my DViCO card, whilst still fixing the original 6Mhz tuning issue.  Please
 merge or let me know how else I should proceed to get this merged.

 Thanks

 -Rob

perhaps the attached notes will help Rob's case here.
I did a few more tests, with just one tuner.
First I changed a cable that I was suspicious of (it was way too long anyway)
but I got no significant improvement.
Then I applied the 'revert2.diff' patch that Rob sent and cold-booted.
I reran the test and got significantly lower BER and UNC values.

There is still something odd going on, in that the UNC seem to get
worse with repeated tunings to the same channel, a few minutes apart
(less than 10min). This might be a
measurement artefact, I don't know. I might try changing the channel
order - that should
test whether the trend of the UNC values is with frequency or order in
the tuning sequence.

2009-12-01 Thread Vincent McIntyre
Hi Rob

I missed your followup and tested the 'revert.diff' patch, attached
for reference.
I have been slow replying because I've been scratching my head over the results.

I used 'signaltest.pl' to test[1], which uses tzap under the hood.
Perhaps this is not the best choice, but I wanted something that I thought would
allow objective comparisons. That's trickier than I thought...
Unfortunately I only discovered last night how easy 'vlc
./channels.conf' makes doing quick visual checks. I didn't have enough
time to re-patch and test again.

My test procedure was:
 - get a baseline with tzap and signaltest.pl
 - patch, make, install. cold boot.
 - test with tzap and signaltest.pl
 - revert patch, for the moment.

I tested two kernels, and both cards. I tested all the tuners but I'll
spare you that for now.

 * 2.6.24-23-rt + v4l (c57f47cfb0e8+ tip)

   I got rather different baseline results. All channels had
significantly higher BER
   than I'd noticed before. After patching, snr on some channels
seemed a little higher
   and BER was lower. On ch9, I think snr was up and BER improved a little.

Hi Rob

would you mind very much posting a patch that implements these two reversions,
so I can try it easily? My hg-fu is somewhat lacking...
I have the same hardware and noticed what I think is the same issue,
just with Channel 9.
Another manifestation is huge BER and nonzero REC in the output from 'tzap'.

 Hi,

 After fixing up a hang on the DViCO FusionHDTV DVB-T Dual Digital 4 (rev
 1) recently via http://linuxtv.org/hg/v4l-dvb/rev/1c11cb54f24d everything
 appeared to be ok, but I have now noticed certain channels in Australia
 are showing corruption which manifest themselves as blockiness and
 screeching audio.

 I have traced this issue down to
 http://linuxtv.org/hg/v4l-dvb/rev/e6a8672631a0 (Fix offset frequencies for
 DVB @ 6MHz)
 Actually, in addition to the above changeset, I also had to revert
 http://linuxtv.org/hg/v4l-dvb/rev/966ce12c444d (Fix 7 MHz DVB-T)  to get
 things going.  Seems this one might have been an attempt to fix an issue
 introduced by the latter, but for me both must be reverted.

 -Rob


 In this change, the offset used by my card has been changed from 275
 to 225.

 The old code which works used to do something like
 offset = 275
 if (((priv-cur_fw.type  DTV7) 
 (priv-cur_fw.scode_table  (ZARLINK456 | DIBCOM52))) ||
 ((priv-cur_fw.type  DTV78)  freq  47000))
 offset -= 50;

 In Australia, (type  DTV7) == true _BUT_ scode_table == 129 == SCODE,
 so the subtraction is not done.

 The new code which does not work does
 if (priv-cur_fw.type  DTV7)
 offset = 225;
 which appears to be off by 500khz causing the tuning regression for me.

 Could any one please advice why this check against scode_table 
 (ZARLINK456 | DIBCOM52) was removed?

 Thanks

 -Rob

 I think the next step at this point is for you to definitively find a
 use case that does not work with the latest v4l-dvb tip and Robert's
 patch, and include exactly what kernel you tested with and which board
 is having the problem (including the PCI or USB ID).

 At this point, your description seems a bit vague in terms of what is
 working and what is not.  If you do the additional testing to narrow
 down specifically the failure case you are experiencing, I will see
 what I can do.

I'm trying to be as clear as I can.

We can forget about setups 1 and 2, they no longer have the messages
from the cxusb module that I originally reported, I can tune and run
signal level tests like [1].

I'm now looking at setup 3.
 os: ubuntu karmic i386
 kernel: 2.6.31-14-generic
 v4l modules: hg identify returns 19c0469c02c3+ tip

 If I cold boot, I see no tuning issues at the kernel level. Details
of the test below.

 The failure I was attempting to report is that
 I am unable to tune with dvbscan or w_scan.
 I think it is due to changes in the V4L API with respect to the versions
 of these programs I have installed.

 However I am able to tune with 'tzap'. I'm not entirely sure why tzap works,
 but it does and it shows the v4l tip drivers are ok regarding the
issue originally
 reported.

 There are two further areas I am looking into.
 1. If I *warm* boot the same setup, I see dvb-usb: bulk message failed:
 in dmesg.
 I am working on this still to try to get a clear report for you of when
 and on which device it occurs. It will probably take me a week to get
 back to you.
 2. There may be differences in performance, in that:
 2.6.31-14-generic+v4l+Rob shows worse Bit Error Rates than
 2.6.31-14-generic+Rob
 Again I have some work to do to clarify this.
 It seems likely it is a separate issue from this thread.

 That said, I'm preparing a tree with Robert's patch since I am pretty
 confident at least his particular problem is now addressed.

I can see no obstacle to you going ahead with that. Thanks again.

Cheers
Vince

Test details:
 I tune like this:
   sudo strace -t -ff -F -o tzap.strace /usr/bin/tzap -a 0 -r -c
channels.conf 7 Digital(Seven Network)

 In dmesg I see the firmware being loaded but no other messages:
   [ 1232.684884] usb 3-1: firmware: requesting xc3028-v27.fw
   [ 1232.743698] xc2028 1-0061: Loading 80 firmware images from
xc3028-v27.fw, type: xc2028 firmware, ver 2.7

(90), id .
   [ 1237.416510] xc2028 1-0061: Loading SCODE for type=SCODE
HAS_IF_5260 (6000), id .

 I can successfully tune each of the 4 tuners in this way. Each time I
run tzap on
 a tuner I've not used before, dmesg shows the firmware loading ok.

Hi Barry,

did you try cold-booting either system?

how are you tuning? mythtv?

Cheers

 Hi Devin
 I tried your tree and I seem to get the same problem on one box I get
 the flood of 'dvb-usb: bulk message failed: -110 (1/0'.

 Can you please confirm the USB ID of the board you are having the
 problem with (by running lsusb from a terminal window)?

 Thanks,

 Devin

Re: bisected regression in tuner-xc2028 on DVICO dual digital 4

2009-11-07 Thread Vincent McIntyre
Hi Devin

 please confirm exactly which of your boards is not working.

Sorry for being unclear.

I have three test setups I am working with, all on the same computer.
1. Ubuntu Hardy, kernel 2.6.24-23-rt and drivers from v4l-dvb tip.
2. Ubuntu Karmic, kernel 2.6.31-14-generic, stock Ubuntu drivers.
3. Ubuntu Karmic, kernel 2.6.31-14-generic, v4l-dvb tip.

Setups 2  3 are the same install, on a separate hard disk from setup 1.
I change between 2  3 by installing the v4l modules or restoring the
ubuntu stuff from backup. (rsync -av --delete).

The computer has two DVB-T cards.

First device is the same as Robert's, I believe. It has two tuners. lsusb gives:
Bus 003 Device 003: ID 0fe9:db78 DVICO FusionHDTV DVB-T Dual Digital 4
(ZL10353+xc2028/xc3028) (initialized)
Bus 003 Device 002: ID 0fe9:db78 DVICO FusionHDTV DVB-T Dual Digital 4
(ZL10353+xc2028/xc3028) (initialized)
I have a 'rev1' version of this board.


Second device is DViCO FusionHDTV Dual Digital Express, a PCIe card
based on cx23885[1] It also has two tuners. lspci gives:
04:00.0 Multimedia video controller [0400]: Conexant Systems, Inc.
CX23885 PCI Video and Audio Decoder [14f1:8852] (rev 02)
Subsystem: DViCO Corporation Device [18ac:db78]
Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr-
Stepping- SERR- FastB2B- DisINTx-
Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast TAbort-
TAbort- MAbort- SERR- PERR- INTx-
Latency: 0, Cache Line Size: 64 bytes
Interrupt: pin A routed to IRQ 19
Region 0: Memory at 9000 (64-bit, non-prefetchable) [size=2M]
Capabilities: access denied
Kernel driver in use: cx23885
Kernel modules: cx23885

With Robert's patch compiled in:
 * On setup 1
  I am able to tune both cards and there are no errors from the cxusb module
   or dvb-usb anymore.
   I tested each of the four tuners, by running dvbscan with
appropriate arguments to
   select the right /dev/dvb/adapterN.

   I just realised I should probably revert the patch and check which
tuners show the
   original problem. Before I was taking the default choice (adapter0,
I think) which is
one of lhe Dual Digital 4 tuners.

 * I have yet to test setup 2,
   I have built the patched kernel module but the box is back 'in
production' right now.
   I plan to test tomorrow.

 * On setup 3. I attempted to tune using dvbscan, w_scan and vlc.
   Again, I was not specific about which tuner the applications should use.
   So to answer your question, I think it is the lsusb id 0fe9:db78
that is unable to tune.
   I will check the tuners individually, tomorrow.

   My impression was that the failures were because of API differences
between the
   applications (all provided as part of the ubuntu install) and the
V4L modules. I have
   not tried to build v4l-apps from the mercurial tree.

So, I hope this makes things clearer. Happy to run tests if you have
any time to look at this.

Kind regards
Vince

 Please excuse the top post. This is coming from my phone.

 Vincent, please confirm exactly which of your boards is not working.
 Roberts patch is not a general fix and only applies to his EXACT
 product .

 please provide the pci/usb I'd in question.

 thanks,

 devin

 I tried this patch, on 2.6.24-23-rt and 2.6.31-14-generic

 On the first, it appears to work fine. Thanks again Rob!

 On the second, while the kernel seems happy I am unable to get any
 applications to tune the card, when I use the latest v4l tree + Rob's
 patch (40705fec2fb2 tip).

  * dvbscan fails with 'unable to query frontend status'

  * vlc is unable to tune as well
