Summary: r600g : lock in desktop display durring piglit test Product: Mesa Version: git Platform: x86-64 (AMD64) OS/Version: Linux (All) Status: NEW Severity: major Priority: medium Component: Drivers/Gallium/r600 AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: xoddark@gmail.com
with the commit : r600g: Allow VRAM for the initial domain for every buffer binding. (b0f1767d776e2c80cab4343b4cd59553fbf5e48a)
I have a "lock" in desktop display during : I can move the mouse, the cursor position is updated. But background display is not updated, and mouse don't interact with desktop.
If I revert this change on git HEAD, I don't have the problem.

this path doen't fix the problem sorry. but i have note that I have the problem with kernel 3.6.39.1, but I haven't the problem with kernel 3.0-rc4.
It seem to be fixed by kernel 3.0. Peraps a modification in drm need to be merged in 2.6.39 branch.

Can you bisect to see what patch fixed the issue?

Peraps, but i probably need help. I don't know how bissect only drm patch, because bissect all patch on kernel 3.0 seems to be very long.
And I need to find how package kernel without rebuild all. For now when i build a kernel, i launch a command who make the build and the packaging. But this command rebuild all each time.

--- Comment #10 from XoD xoddark@gmail.com 2011-07-07 15:19:54 PDT --- I have finish the bisect of kernel 3.0 :
the submit who fix lock i encounter is : 11b0a5b89adbfaf4e7d31f2482f49471dd983692 is the first good commit commit 11b0a5b89adbfaf4e7d31f2482f49471dd983692 Author: Alex Deucher alexdeucher@gmail.com Date: Thu Jun 16 10:06:17 2011 -0400

peraps it have sense to push this patch in branch 2.6.39
At the beginning of bisect, display lock during the first piglit test. But in a second part, display lock only in the second test, when chromium is launch (with some opened page).
