I didn't feel comfortable taking the few r-bs that I had from the RFC except for the one patch that I applied wholesale. Summary: - Completely redid the patch splitting. The number of patches increased, but LOC is about the same, and a handful of the new patches are either because of more splitting, or completely new bits. - Reference counted context allows freeing the data structure and freeing the BO independently. This is probably the most significant change. - Convert ILK RC6 code to use context code. I'm hopefuly this will make things more stable, but have no proof. - Added trace events for context create/destroy/switch. - Only support render ring context switch (previous code supported any ring, though media ring is the only other ring which *should* work). Testing summary. ILK RC6, just booted to desktop SNB module load/unload testing 20 consecutive suspend resume cycles nexuiz with experimental mesa piglit quick.tests with experimental mesa I've seen time-elapsed, and polygonOffset intermittently fail, I believe this is caused by the following... Missed IRQs now seem to occur once every other piglit run. I have some new code to try to fix this... coming soon, I hope. IVB No testing done since RFC I'll respond to this email with links to what I used to test (code is currently not in pushable form). kernel libdrm mesa intel-gpu-tools Thanks to Chris Wilson, Daniel Vetter, and Eric Anholt for providing useful feedback in the RFC.
