This patch series comes with some minor fixes for Panfrost. Some of the issues addressed were uncovered by LLM tools, while the one about RPM was traditionally debugged.
I haven't yet added any Fixes or Reported-By tags, because the purpose of the first revision is probing appetite for these changes and eliciting early discussion. The only proper bug fixes are the ones for perfcnt and RPM, and the others are more about ensuring robustness. perfcnt bug was never observed in the open, because no one had faced a HW reset when a perfcnt session was ongoing. RPM fix addresses a long-standing issue I had been observing for quite some time, but that I had completely misunderstood.
