Hi Ben and list folks, I've been investigating some CI failures with the kms_ccs testcase in the GLK hardware. The original bug is linked below, but there are other more basic tests failing when trying CCS on pipe C. https://bugs.freedesktop.org/show_bug.cgi?id=104096 The reason for the failure is very straightforward, the function skl_check_ccs_aux_surface() in intel_display.c rejects CCS modifiers for PIPE_C, since that is not supported for SKL, KBL and as far as I can tell APL as well. But, since I don't have the specs for GLK yet (it's not available in 01.org), I can't tell if GLK will support it and the kernel must be changed or if the testcase itself is bogus. My money is on the later, but I could use a confirmation before writing down the patch. In short, does pipe C support render compression (ccs modifier) in glk?
