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: [ 93.313995] nouveau 0000:01:00.0: gr: DATA_ERROR 0000009c [] ch 5 [007f6c6000 RenderThread[5395]] subc 0 class a097 mthd 15f0 data 002c0014 [ 93.314082] nouveau 0000:01:00.0: gr: DATA_ERROR 0000009c [] ch 5 [007f6c6000 RenderThread[5395]] subc 0 class a097 mthd 15f0 data 002d0016 [ 93.314112] nouveau 0000:01:00.0: gr: DATA_ERROR 0000009c [] ch 5 [007f6c6000 RenderThread[5395]] subc 0 class a097 mthd 15f0 data 002d0018 [ 93.314215] nouveau 0000:01:00.0: gr: DATA_ERROR 0000009c [] ch 5 [007f6c6000 RenderThread[5395]] subc 0 class a097 mthd 15f0 data 002d001a [ 93.314244] nouveau 0000:01:00.0: gr: DATA_ERROR 0000009c [] ch 5 [007f6c6000 RenderThread[5395]] subc 0 class a097 mthd 15f0 data 002d001c [ 93.314272] nouveau 0000:01:00.0: gr: DATA_ERROR 0000009c [] ch 5 [007f6c6000 RenderThread[5395]] subc 0 class a097 mthd 15f0 data 002d001e [ 93.314301] nouveau 0000:01:00.0: gr: DATA_ERROR 0000009c [] ch 5 [007f6c6000 RenderThread[5395]] subc 0 class a097 mthd 15f0 data 002e0020 [ 93.314325] nouveau 0000:01:00.0: gr: DATA_ERROR 0000009c [] ch 5 [007f6c6000 RenderThread[5395]] subc 0 class a097 mthd 15f0 data 002e0022 Any idea?
