[Intel-gfx] [PATCH 0/2] Two patches for pageflips

[Daniel Vetter]

Hi all,

So in the course of beating the pageflip paths senseless to test the new locking
scheme I've hunted down some bugs on g33. Sometimes we seemingly time out
waiting for the event - apparently the pageflip irq is lost somewhere. I've
tried to dig in, but lost myself completely in the rather fickle vblank mess in
drm_irq.c.

To not write off the last few days completely, I've figured I'll submit the two
sane patches for inclusion - the first should fix fbcon doing stupid things, the
second is purely paranoia (I hope at least). Imho longterm we need to seriously
look at the current vblank stuff - since it operates on pipe ides instead of
modeset crtc objects it's all rather fiddly and easily falls appart. But keeping
both ums and kms paths working is a challenge ...

Comments highly welcome.

Yours, Daniel
