GPU Ctx Init Failed - trying to enable hw acceleration

[oskar]

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()

[   161.874] [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.

The problem is that the libraries from Freescale don't support hard floating point. Timesys had made GPU libraries with hard floating point support. I still don't manage to get X working but at least the crash is resolved.

I verified with the PostGA release, it i loading good, no more error. Make sure kernel modules installed to the rootfs. Below is the log

We've the same issue in L3.0.35_4.0.0_UBUNTU_RFS.

Have any one have solution?
