About Porting Android to nouveau
Hi, guys:
I’m a developer of FydeOS. We porting ChromiumOS to amd64 and arm platforms. Now, I’m woking on porting android environment to Nvidia graphic cards. I have experience to port android to Vmware(SVGA).
I found two display formats were not supported to display in nouveau driver: PIPE_FORMAT_R8G8B8A8_UNORM, PIPE_FORMAT_R8G8B8X8_UNORM. Which are defined at nv50/nv50_formats.c line: 130,131.
