Karol Herbst at Red Hat who has led the work on Rusticl to provide modern OpenCL support for the Mesa GPU drivers has been further improving the AMD Radeon driver support. Herbst shared that he's down to about just ten tests out of around 2,500 tests to hitting OpenCL conformance on the RadeonSI driver.
The handful of OpenCL tests remaining to fix-up for Rusticl + RadeonSI follows this merge request providing a "bunch" of OpenCL CTS crash fixes. That merge request is currently open but will hopefully hit Mesa 23.2-devel soon and as they are fixes could still be back-ported to the Mesa 23.1 series.
