--- Comment #3 from Andrew Randrianasulu <randrik at mail.ru> ---
Sorry, my mesa tree was not properly cleaned, and this resulted in weird mesa
git version string. After running  make distclean +  git clean -fdx + 
./autogen.sh --prefix=/usr --disable-dri3 --with-gallium-drivers=nouveau
--enable-texture-float --enable-debug --with-dri-drivers=swrast
PKG_CONFIG_PATH=/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 image.

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 xvmc
on old kernels on my hardware, and try to move forward by investigating why new
kernel  failed to create device/object for pmpeg...
