[Nouveau] [libdrm 05/13] nouveau: add interfaces to query information about supported classes
From: Ben Skeggs <bskeggs at redhat.com>
This will expose functionality supported by newer kernel interfaces.
Current userspace uses the chipset to determine which classes are likely
exposed, which generally works pretty well, but isn't as flexible as it
could be.
Unfortunately, the G98:GF100 video code in Mesa is still relying on the
kernel exposing incorrect vdec classes on some chipsets. The ABI16
kernel interfaces have a workaround for this in place, but that will no
longer be available once libdrm supports NVIF.
To prevent a regression when NVIF support is added, if there's no kernel
support for NVIF, libdrm will magic up a class list containing correct
vdec classes anyway instead of failing with -ENODEV.

[Nouveau] [libdrm 06/13] nouveau: introduce object to represent the kernel client
From: Ben Skeggs <bskeggs at redhat.com>
Because NVIF intentionally lacks some of the paths necessary to be
compatible with various mistakes we've made over the years, libdrm
needs to know whether a client has been updated and that it's safe
to make use of the new kernel interfaces.
Clients still using nouveau_device_open()/wrap() will be forced to
make use of ABI16 instead of NVIF.
