[PATCH 0/9] drm/i915: Some more FBC stuff

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Another set of FBC patches, which should fit on top of the previous set:
"[PATCH 00/10] drm/i915: FBC fixes v2"

The persistent mode and HT tracking bit stuff is a bit unclear in the docs,
but I can remove it all, and everything still seems to work fine.

The page flip and dirtyfb stuff is maybe a bit raw, but I'll post anyway
now since it seems to work for me.

I'll post my igt test case that tries to stress all this shortly. It passes
for me on ILK, SNB and IVB. On ILK it's a bit limited since there are no
contexts (didn't try the ILK context patches w/ this) and we're missing
a gen5 rendercopy, so I couldn't test the render tracking using igt. But I
don't get any screen corruption w/ FBC enabled, so it must be working.

The only FBC1 capable hardware on my desk is a MGM, but someone was a bit
too conservative when they implemented FBC1 support and enabled it only 
for CL. I was too lazy to read through the code to see if it should work
for MGM.
