As the biggest thing it adds multi-LRC (parallel) submission implementation for GuC and a simplified parallel submission uAPI to go with that (only works with GuC for now). It is has a similar mission to the bonded submission uAPI, take a look at the kerneldocs for full detail. Then there are some improvements to making sure old pages are flushed from caches before making them available to userspaces. Those extra flushes may be visible in corner case scenarios if application is frequently importing new dmabufs on non-LLC hardware. The better approach would anyway be to recycle a pool of dmabufs than destroy and recreate. In addition to that, it's only minor changes with mainly developer impact and those can be seen in shortlog. Regards, Joonas PS. There has been request to backmerge drm-next after you merge this PR, to bring in dma-resv iterators. I'll do that. PPS. Will send out the dim patches for the "for-linux-next-gt" branch updating to make sure we avoid the future conflicts. *** drm-intel-gt-next-2021-10-21: UAPI Changes: - Expose multi-LRC submission interface Similar to the bonded submission interface but simplified.
