imx6q GPU tests fails on Linux buildroot 4.9.88

Contributor I



I am using buildroot (2020.02.4) with linux kernel 4.9.88 and configs are based on up-stream, the GPU driver seems to be loaded successfully from what I see in dmesg output:

[ 0.921687] mmc1: SDHCI controller on 2194000.usdhc [2194000.usdhc] using ADMA
[ 0.924531] mxc_vdoa 21e4000.vdoa: i.MX Video Data Order Adapter(VDOA) driver probed
[ 0.928405] galcore: clk_get vg clock failed, disable vg!
[ 0.928608] Galcore version
[ 0.951741] usb 1-1: new high-speed USB device number 2 using ci_hdrc
[ 0.979735] mmc1: host does not support reading read-only switch, assuming write-enable
[ 0.985896] mmc1: new high speed SDHC card at address 59b4
[ 0.996848] mmcblk1: mmc1:59b4 USD 7.51 GiB F


However when I try to run examples in "/usr/share/examples/" I get error messages for both "g2d_samples" and "viv_samples", as follows: 

# ./g2d_test
g2d_open: fail with status -7
g2d_open fail.


and for "viv_samples" :

# ./clinfo

>>>>>>>> ./clinfo Starting...

!!! Error # -1001 at line 156 , in file main.cpp !!!

!!! Exiting...


I was wondering if someone could provide me with some help that what might be wrong and how possibly fix it.

Thank you in advance
