Does 6.17-rc7 work for you? We need to know if this needs to be fixed in just the stable tree or if it is something that needs to be addressed in mainline as well.
6.17-rc7 boots fine, so the issue is just in the stable tree.
Thx. Could you also try if reverting the patch from 6.16.y helps? Note, you might need to revert "drm/xe/guc: Set RCS/CCS yield policy" as well, which apparently depends on the patch that causes your problems.
Just wondering: why are those parameters needed? Is the hardware not fully supported be the xe driver yet?
i915 is still the default driver for Meteor Lake integrated GPUs, so that's why I need to pass those parameters. Lunar Lake already uses Xe by default, though. In my experience, for at least the last two kernel release cycles, I've observed better battery life and performance using the Xe driver.
Thx for letting us know!
