Message-ID: Hello everyone! I am trying to enable glamor in my experimental project.Under debug mode I found that glamor_copy_fbo_cpu path is never taken in glamor_copy_gl. Unfortunately I have not seen any pixels on the screen. I have no idea if this is the problem. I am doing this on the platform based GBM, so I think since gbm_bo is both used for RENDERING(renderbuffer) and SCANOUT(framebuffer), it is not necessary to copy pixels from GPU to CPU, they are always in the VRAM. Is my understanding correct? -------------- next part -------------- An HTML attachment was scrubbed... URL:
