换成4.19的内核也不行，现在的问题是 不管overalloc更改成200，还是300，系统中的y_virtual 都是600

Error: eglCreateWindowSurface failed: 0x00003003见了鬼了
A33的GPU有两个方向，开源的Lima和非开源的全志OpenGL库
Lima+Mesa3D
LIMA只需要在内核选上LIMA和SUN4I的DRM驱动即可
Mesa3D可以在buildroot选上
不过最后我运行mesa的demo直接出错也找不到问题就放弃了，不知道是哪里的问题，网上教程太少不会玩。这时候我切到第二个方案：
其实教程就是https://github.com/mripard/sunxi-mali但是这里有个坑（我选的fbdev的库），导致一运行malitest就出错（malitest可以自己编一个https://github.com/linux-sunxi/sunxi-mali/tree/master/test）
查资料得到了信息
1. Must enable DRM_FBDEV_LEAK_PHYS_SMEM from kernel
2. set drm_leak_fbdev_smem on compile time (for some reason, passing in command line did not help) in drm_fb_helper.c
3. use latest r8p1这回终于跑起来了
malitest和QT的OpenGL例子都运行正常
对了，最好在buildroot里选上sunxi-mali-mainline，这样它会自动给你生成一个启动时加载mali.ko的脚本。
当然，自己modprobe也是可以的运行malitest的结果，可以验证是否正确
这里有点比较老的介绍，虽然过时了，但是比较系统
https://linux-sunxi.org/Mali_binary_driver
我这边运行 test 程序直接出现 Error: eglCreateWindowSurface failed: 0x00003003
查询错误码 是 EGL_BAD_ALLOC， 用的r8p1 fbdev ，你又遇到这个问题吗？

咋弄好的？
我把u-boot精简掉的选项又加回去了，就好了
你的axp223各电源的名字，在设备树文件里是如何更改来适配这个开发板的或驱动的，
我这边启动的过程中有几路电源，驱动找不到呢，启动完成后屏幕会黑掉，貌似背光关闭了

无论用哪个口 0 ～ 3 都是返回同样的错误：
UMS: LUN 0, dev 1, hwpart 0, sector 0x0, count 0x748000
Controller uninitialized
g_dnl_register: failed!, error: -6
g_dnl_register failed
看上去是usb控制器没有初始化，但是使用 usb tree 命令，又可以列出两个控制器上的设备，应该是已经初始化了的
=> usb tree
