--- Comment #21 from Mauro Rossi issor.oruam@gmail.com --- Created attachment 116054 --> https://bugs.freedesktop.org/attachment.cgi?id=116054&action=edit dmesg (without drm.debug=7) and logcat for HD7950
Hi,
here is dmesg, without drm.debug=7, and logcat collected on HD7750 with VA BO proposed patch applied.
VA conflict is still happening.
<3>[ 807.802668] radeon 0000:01:00.0: bo f085f400 va 0x0000001138 conflict with (bo f183c400 0x000000121c 0x000000121d)
[behavior without RADEON_VA_UNMAP patch, i.e. initial status]
Without the VO BO patch applied, GUI was stable on HD7750 and HD7950 and many OpenGLES apps were fine (Gears, Rajawali, Harism Effects, Harism Shaderize, and Antutu benchmark could not be launched, failure in allocating bo for 'atlas' (NOTE: idk what 'atlas' is). OpenGLES 1.0 Demo com.rtsw.opengldemo cannot reach the second cube demo (app crashing and GUI restarting).
[behavior with RADEON_VA_UNMAP patch] Logcat logs are showing "GPU lockups" that cannot be recovered until reboot, we also see intermittent GUI instability and GUI sometimes is not starting. Antutu can start and pass the 'atlas' bo allocation, but cannot complete 3D tests. OpenGLES 1.0 Demo com.rtsw.opengldemo cannot reach the second cube demo (app crashing and GUI restarting).
It's strange that OpenGLES 1.0 Demo is not workinh either ways.
Question (please be patient I'm not skilled as you are): could some of these problem due to multicore, hyperthreading or be cacheing related?
If it can help, I can provide further logs with kernel parameters maxcpus=1, maxcpus=0 or by disabling hyperthreding in the BIOS.
If problems were cacheing related, is there a way to highlight this?
