GPU Ctx Init Failed - trying to enable hw acceleration

oskar — Thu, 03 Jan 2013 13:17:21 GMT

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.

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?

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.
