后续测试，以下几个qt的QML都报错：DRM_IOCTL_MODE_CREATE_DUMB failed: Cannot allocate memory
构建过程好像没有要配置显存的地方，现在内核都不需要另外配置显存区域大小了吗？

glmark2 Score: 51
=======================================================继续记录聊天记录:
开mali的时候QGLWidget跑不了
开了mali之后用QGLWidget就不报错了,内容也可以显示CPU占用率明显降低了
Widget跑,2层窗口半透明情况下CPU占用率可以高到40%多,连鼠标都能感觉到卡顿
一个窗口占用率20%左右
现在的CPU占用率区区5%
threadedqopenglwidget 这个Qt demo，你那里运行正常吗？我这边EGLFS全是黑，X11全蓝。

对我是关掉lima也有card0，可以正常刷屏。如果开了lima我是card0和card1
那就奇怪了，我这就没有。但是我可用看到 /sys/bus/platform/devices/ 有以下设备：
1c40000.gpu -> ../../../devices/platform/soc@01c00000/1c40000.gpu
1e60000.display-backend -> ../../../devices/platform/soc@01c00000/1e60000.display-backend
display-engine -> ../../../devices/platform/display-engine
会不会是文件系统没帮我创建呢？
明年能用你的config来试实在就太好了！请问你用的内核版本是哪一个？
我启动log里头有一项跟drm有关的，不知道是不是这个问题：
systemd[1]: Condition check resulted in Load Kernel Module drm being skipped.
lima实在搞不定，折腾了几天。应该还是卡在drm那里。

作为新手，使用主线配置这两项。并在 arch/arm/boot/dts/sun8i-a33-sinlinx-sina33.dts 也加上了ok,就是没看见/dev/mali设备。暂时尝试失败。
