imx6q GPU测试在Linux buildroot 4.9.88上失败

如何解决imx6q GPU测试在Linux buildroot 4.9.88上失败

我正在使用带有Linux内核4.9.88的buildroot（2020.02.4），并且配置基于上游。我从dmesg输出中看到的内容似乎已成功加载了GPU驱动程序：

[ 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 6.2.4.150331
[ 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

 

但是，当我尝试在“ / usr / share / examples /”中运行示例时，出现了两个“ g2d_samples”的错误消息：

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

以及“ viv_samples”：

# ./clinfo

clinfo Starting...

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

!!! Exiting...

我想知道是否有人可以为我提供一些有关什么地方可能出问题以及如何解决的帮助？
