Summary: Mouse cursor stutter with kernel 2.6.35
Product: DRI
Version: unspecified
Platform: x86-64 (AMD64)
OS/Version: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: DRM/Radeon
AssignedTo: dri-devel@lists.freedesktop.org
ReportedBy: mjulien.m@gmail.com
Hi,
since I upgraded to kernel 2.6.35, my mouse cursor is not fluid anymore. When I
move it, it stutters sometimes (that is, it makes a small jump on the screen).
According to latencytop, it seems to come from drm_mod_cursor ioctl which takes
as much as 100ms when the cursor jump. I attach a screenshot of latencytop
window.
This issue seems to appears randomly, maybe more frequent when the cursor
change (arrow to select hand etc.) but I'm not sure.
I don't have this problem with 2.6.34 (nor 2.6.34.1 and 2.6.34.2 ).
I'm using vanilla kernel (packaged by my distro but without any third party
patch) :
Linux tue-amour 2.6.35-1mdv #1 SMP Mon Aug 2 05:50:00 UTC 2010 x86_64 x86_64
x86_64 GNU/Linux

radeon driver 6.13.1 with KMS
mesa 7.8.1
libdrm 2.4.21
radeon 4870, only one screen attached.
