--- Comment #5 from Mika Kahola mika.kahola@intel.com --- Created attachment 145430 --> https://bugs.freedesktop.org/attachment.cgi?id=145430&action=edit gem_render_copy --run-subtest y-tiled-ccs-to-linear
Unfortunately, the rendercopy patches didn't help in case of CCS. The attatched dmesg is an example of the outcome of IGT test gem_render_copy@y-tiled-ccs-to-linear.
I ran the test with my IGT tree
