drm/radeon/kms: MC vram map needs to be >= pci aperture size
|
||||
|
||||
The vram map in the radeon memory controller needs to be
|
||||
>= the pci aperture size. Fixes:
|
||||
https://bugs.freedesktop.org/show_bug.cgi?id=28402
|
||||
|
||||
The problematic cards in the above bug have 64 MB of vram,
|
||||
but the pci aperture is 128 MB and the MC vram map was only
|
||||
64 MB. This can lead to hangs.
