GPU Ctx Init Failed - trying to enable hw acceleration

Question asked by oskar on Jan 3, 2013
Branched to a new discussion

Board - i.MX6Q SD + "i.MX 6Dual/6Quad Linux Reference Manual" - Chapter 12 - X Windows Acceleration.


In xorg.conf, if I set "fbdev" as Driver in section "Device" - system is starting, hardware acceleration is not available.


I installed gpu-viv-bin-mx6q_12.09.01-1_armel.deb and xserver-xorg-video-imx-viv_12.09.01-1_armel.deb. The xorg.conf file has been changed - "vivante" as Driver. The content looks similar to the description in "12.3.4 xorg.conf for i.MX 6".

Unfortunately the result is different than I expected - screen is black. Also in Xorg.0.log I see some errors:


[   161.393] (II) VIVANTE(0): test Initializing EXA

[   161.394] (EE) VIVANTE(0): internal error: GPU Ctx Init Failed

[   161.394] (EE) VIVANTE(0): internal error: initExaLayer failed in VivScreenInit()

[   161.394] (==) VIVANTE(0): Backing store disabled

[   161.404] (==) VIVANTE(0): DPMS enabled

[   161.874] [drm] failed to load kernel module "vivante"

[   161.874] (EE) VIVANTE(0): [dri] DRIScreenInit failed.  Disabling DRI.


Unfortunately I cannot find solution or reason of the problem.
