This came out of some debugging I was doing to figure out how BE mode works on this hardware. Among other things, it came out that we're not exposing 16-bpp mode support and that the ARGB8888 mode that we do expose is broken. Also the overlay logic was pretty broken, I must have only tested with very "normal" overlay buffer sizes with modetest before. That said, this code has only received literal testing on a NV34/G5 PPC combo. I was poking at various registers on a NV34/x86...

This was all kicked off by me figuring out how the PPC byteswap thing worked. In the end, we're keeping the implicit byteswap based on architecture, but also expose the correctly supported formats, and fix some overlay details. Overlay framebuffers have various funky requirements that should be enforced at framebuffer creation time (these are set apart by their YUV formats). Further, I

...d. How to reproduce: 1. Create an EGL context with these attribs: static const EGLint config_attribs[] = { EGL_RED_SIZE, 1, EGL_GREEN_SIZE, 1, EGL_BLUE_SIZE, 1, EGL_ALPHA_SIZE, 1, EGL_NONE, }; Set platform to EGL_PLATFORM_GBM_MESA and visual to GBM_FORMAT_ARGB8888. 2. Try to get the alpha size: eglGetConfigAttrib(EGL_ALPHA_SIZE) glGetIntegerv(GL_ALPHA_BITS) Both return 8, meaning an alpha channel is present. 3. Try to read pixels with glReadPixels and GL_BGRA_EXT. The resulting image has an alpha channel which sets the pixels to be completely transparent...
