Vblank is slightly missed
Hello everybody,
I am running:
- user-space: Ubuntu Karmic + Xorg/drm/mesa from Lucid
- kernel-space: drm-radeon-testing + patches 0001 to 0030
on an "ATI Technologies Inc Mobility Radeon HD 2400".
It seems to me that the vblank is "slightly" missed. When the power state changes the screen jumps a little bit. With drm-radeon-testing (w/o patches) a horizontal line appears randomly on the screen. Also, dmesg says:
The power consumptions seems 200mA bigger than fglrx.
Anyway, thanks for all the work, the open-source stack with KMS works like a charm.
Cheers,
Cristi.
