Description Mika Kahola 2019-09-12 07:16:40 UTC 
gem_render_copy is failing on CCS subtests on TGL

y-tiled-ccs-to-linear
y-tiled-ccs-to-x-tiled
y-tiled-ccs-to-y-tiled
y-tiled-ccs-to-yf-tiled
yf-tiled-ccs-to-linear
yf-tiled-ccs-to-x-tiled
yf-tiled-ccs-to-y-tiled
yf-tiled-ccs-to-yf-tiled

It seems that at least, rendercopy support for GEN12 is missing from upstream IGT.

Comment 2 Chris Wilson 2019-09-12 11:20:05 UTC 
There is no render copyfunc for gen12. This should have bailed out at

                data.render_copy = igt_get_render_copyfunc(data.devid);
                igt_require_f(data.render_copy,
                              "no render-copy function\n");
Comment 3 Mika Kahola 2019-09-12 13:07:29 UTC 
You're right. I had a patch in my tree which, for some reason, hasn't been upstreamed yet. But the bug is real, we are missing rendercopy function for GEN12.
Comment 4 Katarzyna Dec 2019-09-13 04:58:54 UTC 
Patches for Gen12 are ready, I will resend them today.

Created attachment 145430 [details]
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

Forward duping to tie in with cibuglog.
