Hello again. Not sure if anyone will look into this, but I run into bug where xvmc state tracker/nouveau failed for me in multiple ways, depending on exact kernel/m= esa combination. With kernel 4.2.0 new mesa (Mesa 17.1.0-devel git-12dcad1) compiled agains recent libdrm (d4b8344363b4e0f0e831e5722b6df5cc0bb08df8 Author: Chad Versace <ch= adversary@chromium.org> Date: Fri Jan 27 12:18:00 2017 -0800 Bump version for 2.4.75 release) produces pink window. With more mdoern kernel (4.10-rc5). whole device creation failed. Test commandline: /home/guest/src/mesa/src/gallium/state_trackers/xvmc/tests/xvmc_bench result: Acceleration level: IDCT Creation failed: No such device (-19) xvmc_bench: tests/xvmc_bench.c:238: main: Assertion `XvMCCreateContext(disp= lay, port_num, surface_type_id, config.input_width, config.input_height, 0x00000= 001, &context) =3D=3D 0' failed.

--- Comment #3 from Andrew Randrianasulu ---
Sorry, my mesa tree was not properly cleaned, and this resulted in weird me=
sa
git version string. After running make distclean + git clean -fdx +=20
./autogen.sh --prefix=3D/usr --disable-dri3 --with-gallium-drivers=3Dnouveau
--enable-texture-float --enable-debug --with-dri-drivers=3Dswrast
PKG_CONFIG_PATH=3D/usr/local/lib/pkgconfig:/usr/lib/pkgconfig it shows more
correct rendering string :
OpenGL version string: 2.1 Mesa 17.1.0-devel (git-ce7a045)
but issue with xvmc still here.
I tried to boot old Slackware kernel (vmlinuz-huge-smp-3.14.29-smp) and
unfortunately it behaved like my 4.2.0 with new mesa/libdrm: no correct ima=
ge.
vmlinuz-huge-smp-4.4.14-smp (new Slackware kernel) behaves like my
self-compiled 4.10-rc5: "Creation failed: No such device (-19)"
So, I think for now I can conclude new userspace simply doesn't work for xv=
mc
on old kernels on my hardware, and try to move forward by investigating why=
new
kernel failed to create device/object for pmpeg...

--- Comment #4 from Ilia Mirkin ---
FWIW with mesa 17.0.1 and kernel 4.10.4, I'm unable to fully reproduce the
issue. I have a NV4A, which uses the nv44 mpeg object, which in turn is rat=
her
different than the "plain" nv40 one which you have.
I get a ton of warnings in dmesg:

OK, so the NV4A actually runs into a different issue - the MPEG class can o=
nly
take linear memory, but the PCI GART is paged. So it can't deal the CMD/DATA
bo's. When moving those to VRAM (in mesa), the NV4A is fine. I plugged a NV=
42
in with much worse results. On boot I get:
https://hastebin.com/datuzivebu.sql
[ 10.110345] nouveau 0000:04:00.0: mpeg: ch -1 [unknown] 03100023 ffffffff
00000001 ffffffff
[ 10.191580] nouveau 0000:04:00.0: mpeg: MSRCH 0xffffffff
And just all kinds of fail. This is with some local patches to print the ex=
tra
stuff out. Feels like it's not getting powered on (all those 0xffffffff's) =
in
MC.

--- Comment #6 from Ilia Mirkin ---
Er, scratch that. I guess the board doesn't have enough power when there's a
second GPU in another PCIe slot. It comes up fine now, and I get the same
issue.
Looks like this bit of nvkm_ioctl_new is somehow failing with -ENODEV. My
latest theory is:
nvkm_fifo_chan_child_new calls engine_ctor (nv40_fifo_dma_engine_ctor), whi=
ch
in turn calls nvkm_object_bind() on something it's not supposed to (like the
engine object, I think), which in turn returns -ENODEV as there's no bind
pointer. I suspect the solution here is to add a dummy .bind to nv31_mpeg_c=
han,
since the binding effectively happens at chan_new time. Or we could move the
mpeg->chan check to the bind action.

--- Comment #7 from Ilia Mirkin ---
OK, looks like this isn't so trivial to solve. The code really likes having
something in chan->engn[] so that it can get the address. The old code just
stuck a "4" in if it was a non-GR class. I wonder if the current code should
check for ->engn[] !=3D null, and if it's null, use a 4 there for the inst
address.
This will need consultation with Ben, as this is well outside my knowledge
area.
