I revised the diagnostic patch (assert_fb_bound_for_plane) so that the function comment actually matches what the function does and ran it on a couple of machines whilst bug hunting. It scored 2 direct hits. Not only does intel_get_load_detect_pipe() not attach a framebuffer when enabling an unused pipe, but the intel_crtc_mode_set() enables the plane before setting up the memory for the plane to read from.
The latter is quite a scary bug. Can anyone remember if there was a reason for it to be so? -Chris _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/intel-gfx
