Besides ongoing issues with patch acceptance and thus overall progress, there’s also an increasing issue with testing coverage: The more complex the emulator (APX support in particular is going to add various new aspects), the more problematic it is that testing coverage isn’t quite as good as it probably should be. One particular corner case I’d like to collect ideas on is that with gcc planning to remove KNL/KNM support in version 15, we’re not going to be able to “monolithically” build / test the full range of what we presently have test coverage for (without whatever adjustments or suitable workarounds).
