By default weston-simple-dma-egl uses DRM_FORMAT_XRGB8888 which in the panfrost driver ends up as PIPE_FORMAT_B8G8R8_UNORM and panfrost_afbc_format() returns PIPE_FORMAT_NONE for that. Change the format to DRM_FORMAT_ABGR8888 using weston-simple-dma-egl -f 0x34324241. This ends up as PIPE_FORMAT_R8G8B8A8_UNORM in panfrost_afbc_format() which is a supported format. > > I have a buildroot system with weston-10.0.9 and mesa 21.3.5. > > After launch weston, I run weston-simple-dmabuf-egl, but from the output > > of sys/kernel/debug/dri/0/state, the weston is still use Smart0-win0, which > is > > a non-AFBC window. > > Do i need to modify the vop2 driver to set one Cluster window as primary > plane? I never used a Cluster window as primary plane.
