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.
C4(A, R8G8B8A8_UNORM, RGBA8_UNORM, R, G, B, A, UNORM, A8B8G8R8, IB),
F3(A, R8G8B8X8_UNORM, RGBX8_UNORM, R, G, B, xx, UNORM, A8B8G8R8, TB),
I want the last params to be “TD” or “ID” (support
PIPE_BIND_DISPLAY_TARGET) , to support android. I modified these code, but got
display issues and kernel issue:
