Hello Michel,
as this is for radeon, do you think this could/should fix
the wrong reported VRAM size with Unigine_Heaven/-Valley, too?
Maybe speed things up? ;-)
Unigine_Valley-1.0
GPU: Unknown GPU x1
System memory: 24102 MB
Video memory: 256 MB
Sync threads: 7
Async threads: 8
I'll try patching openSUSE Kernel:stable 4.9.6-2 with this
and maybe this could then go into 4.10-rc7 'cause it is a
bugfix. - Alex?
Greetings,
Dieter

vram_size is supposed to be the total amount of VRAM that can be used
by
userspace, which corresponds to the TTM VRAM manager size (which is
normally the full amount of VRAM, but can be just the visible VRAM when
DMA can't be used for BO migration for some reason).
The above was incorrectly used for vram_visible before, resulting in
generally too large values being reported.
