IMX6Q X11 Vivante GPU acceleration Segmentation Fault

[npatel]

Hi,

I am currently facing issues when trying to start X11 with Vivante GPU acceleration. This is on a custom board, using the NXP 4.14.98_2.0.0 GA Linux Kernel. I am currently using:

X.Org X Server 1.20.4

imx-gpu-viv_6.2.4.p1.8

xf86-video-imx-vivante  -->
SRCREV = "b765c3ffc0dcc4246afa659aa0d59f78a6736b08"
SRCBRANCH = "imx_exa_viv6_g2d"
SRC_URI = "git://source.codeaurora.org/external/imx/xf86-video-imx-vivante.git;protocol=https;branch=${SRCBRANCH}

Galcore version: 6.2.4.150331 (from NXP 4.9.88_2.0.0 GA Linux kernel release, which is the one that works)

Here is Xorg log, in which a segmentation fault occurs:

What are the recommended versions of Xserver, imx-gpu-viv, and xf86-video-imx-vivante to use with NXP kernel 4.14.98_2.0.0 GA?

Thanks,

Hello Neil,

Your issue is problem with the memory, try to run DDR stress tool, for X11 you must download the vivante 5.0.11 driver version, because the 6.2 is for DRM. download the L4.1.15 BSP.

Regards
