Subject: [RFC/PATCH xf86-video-intel] sna: Let modestting + glamor handle
|
||
|
|
gen9+
|
||
|
|
|
||
|
|
sna has no meaningfull accel for gen9+, this causes problems with i.e.
|
||
|
|
apps using XVideo since the sprite XVideo support does not work well
|
||
|
|
for many apps.
|
||
|
|
|
||
|
|
Therefor it is better to just let the xserver fall back to modesetting +
|
||
|
|
glamor. This is implemented by returning FALSE from the probe methods,
|
||
|
|
just like how nouveau handles falling back to modesetting for newer cards.
|
||
|
|
