From CI runs you may see these errors
[drm:display_pipe_crc_irq_handler [i915]] *ERROR* CRC buffer overflowing For a real fix, should we increase the size of ringbuffer where crc's are stored or in the kms_plane_multiple test wait for a while before running the next iteration? > -Chris > > -- > Chris Wilson, Intel Open Source Technology Centre _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/intel-gfx
