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

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. ~Maarten

Maybe your distro has one in path, you could try strace to see where it gets libvdpau_nouveau.so from.> The way I got the mmiotradce is this: I downloaded and installed the 313 > blob for my Chakra default kernel " sudo pacman -S nvidia" > > I rebooted back to the desktop.

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. ~Maarten
