Summary: [RV620][REGRESSION] Lock up after "Fix R600/RV770
disable acceleration path" (KMS)
Product: DRI
Version: unspecified
Platform: Other
OS/Version: All
Status: NEW
Severity: normal
Priority: medium
Component: DRM/Radeon
AssignedTo: [email protected]
ReportedBy: [email protected]
I use notebook with M82==RV620. When playing with KMS I get lock up after 5-20
secs of using KDE4. Sometimes it's just black screen, sometimes it's black,
sometimes SysRq work, sometimes not. Does following commit look like guilty
one? AFAICS it should touch disabled acceleration only, right? And
xf86-video-ati enables EXA for me:
(II) EXA(0): Driver allocated offscreen pixmaps
(II) EXA(0): Driver registered support for the following operations:
(II) Solid
(II) Copy
(II) Composite (RENDER acceleration)
(II) UploadToScreen
(II) DownloadFromScreen
(II) RADEON(0): Acceleration enabled

75c8129893d78fd0cbe5c26580cadd6001d904fc is the first bad commit
commit 75c8129893d78fd0cbe5c26580cadd6001d904fc

drm/radeon/kms: Fix R600/RV770 disable acceleration path
When acceleration doesn't work we should free associated memory
and stop GPU block responsible for hardware acceleration so we
don't waste resource or let think one component of the driver that
a GPU feature is working/running while it doesn't actualy work.
