vdpau problems and logging

Dear all,
             I'm writing about  setup  vdpau firmware with  the nouveau
driver according to this page:

http://nouveau.freedesktop.org/wiki/NVC0_Firmware  I have  installed  the
nvidia-313 binary drver to attempt  to extract  the firmware. I have
obtained another mmiotrace  using  my  default  kernel I have installed  on
my Chakra  Distrobution.  I  have  used  the  instructions  on the  wiki
page.


I  had some mixed results using the instructions. I didn't get anywhere
with  using the demmio  from rnn  in envytools, but  I have  got some
output using  the demmio  command.

I will  be  uploading the output  in different files.  I did only once get
lucky with the last instructions, valgrind , but I can't seem to  get any
more "vuc" files. I hae saved the ones  I have and put them into
"/lib/firmware/nouveau"  and  I have copied  them into my external hardrive.

I  have tried  playing a  .mkv video which  I know it works  with the  313
binary driver.
I know it doesn't work  with  the  nouveau  driver and the "vuc" files I
extracted.

I will  upload  all  the  output I have created In tar.xz  format  attached
to a  series  of e-mails.

Regards,
              Steve555

Are you on an ancient xserver-xorg-video-nouveau by any chance? Anything from
2012 or later should be good enough, it's commit d575a28a502 that tells it to
load libvdpau_nouveau.so instead of nvidia. You might need to update libvdpau too.

The vuc files are probably ok, but it's not going to work without the kernel firmware files.

The ones I'm getting are:
vuc-h264-0  vuc-mpeg12-0  vuc-mpeg4-0  vuc-mpeg4-1  vuc-vc1-0  vuc-vc1-1  vuc-vc1-2

This is enough for all codecs, but it will just fail later on without userspace codecs. It should
attempt to create the kernel stuff first, which it doesn't from what I can tell from your logs.

Are you sure it's picking up the right vdpau_nouveau though? Maybe your distro has one in path, you could try strace to see where it gets libvdpau_nouveau.so from.

You don't need to play an actual video, just having mplayer initialize video is enough.

The nvidia module must be unloaded before you start your mmiotrace, easiest is to ssh into the machine.

The script I'm using for mmiotrace is:

http://people.freedesktop.org/~mlankhorst/mmiotrace-nvidia.sh

Connect to the machine with ssh, make sure your display manager is stopped, and nvidia module is unloaded,
then run the script and in the shell it spawns, type:

/usr/bin/X :0

sleep 5 # if you copy paste, give it some time to init, if not just skip this and wait 5 seconds

DISPLAY=:0 envytools/vdpow/mmt_ufw
# check if it returns any errors like unable to connect to display, if not you're good

exit 0

The mmiotrace should be in /tmp/current_trace.txt now, and have all the kernel firmwares you need.
