            Bug ID: 111667
           Summary: gem_render_copy failing on CCS subtests
           Product: DRI
           Version: DRI git
          Hardware: Other
                OS: Linux (All)
            Status: NEW
          Severity: major
          Priority: not set
         Component: IGT
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: mika.kahola@intel.com

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.

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");

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.

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
