Hi, this is buffer objects tracking implemented in v7
For example,
[root@fedora 0]# pwd
/sys/kernel/debug/dri/0
[root@fedora 0]# cat chip
I'm in LS7A2000, running on cpu 0xc0, cpu revison: 0x11
[root@fedora 0]# cat bos
bo[0000]: size: 8112kB VRAM
bo[0001]: size: 16208kB VRAM
bo[0002]: size: 16kB VRAM
bo[0003]: size: 16kB VRAM
When using with modesetting driver with shadowfb option enabled.
by default we have only 4 BOs create, the first one is for fbcon, the
largest one is framebuffer of double screen.
another two is hardware cursor bo. Our system page size is 16KB by default.
