全志A733多屏异显怎么解决master问题

A733 buildroot开发双屏异显
# 应用逻辑是这样的：
依次运行A进程，B进程，A进程显示图片到MIPI屏幕，B进程显示图片到HDMI屏幕
# 问题：
只有第一个运行的进程能点亮屏幕，另一个进程会报错没有权限，也就是AB进程谁先运行，谁就能显示，后运行的进程没有drm权限，查询资料发现问题源于DRM的master问题，即：只有第一次调用的drm句柄默认成为master，另一个进程在调用drm就无权限提交显示，目前查到的解决方案就是A进程启动后，通过drm lease机制，租一部分资源给B进程，这样B进程就能使用drm了。据说，主线kernel也是这样处理的。

我觉得这种太不灵活了，如果有桌面系统xfce或安卓系统倒是不用考虑这个问题，但是基于buildroot直接推送显示buffer到drm的简单方案就很麻烦了，我理解的是DRM框架每个屏幕对应一个CRTC，每个CRTC下面有多个Plane,Plane里面的buffer就是最终显示在屏幕上的图像.

比如接了DSI屏幕和HDMI屏幕，驱动加载后会为两个屏幕各分配一个CRTC id,CRTC也对应的一组Plane,如DSI屏幕分配了4个plane,HDMI分配了3个Plane,那么一共有7个可以显示的平面，在RK3568上可以7个进程各自推送一个buffer到plane，同一个屏幕的plane显示层级是ZPOS决定的，ZPOS最大的显示在最上层。

全志的DRM驱动应该也是可以做到这种效果的，毕竟CRTC是独立的，一个进程显示其中一个屏幕的时候，另一个屏幕是空闲的，不存在冲突的啊？欢迎个位大佬分享见解
