We have a couple of pieces of code that wish to take further advantange of prolonged vmappings: execlists (ringbuffers), the cmdparser and the GuC (workqueues). This series refactors the whole-object vmapping code and caches it on the drm_i915_gem_object until it is released along with the object's pages (i.e. under memory pressure or at the end of the object's lifetime). This was stalled until we had a notifier in place from the mm/vmalloc for when we ran out of vmalloc arena (quite possible on 32bit machines which only reserve ~128MiB globally).
This should unblock a couple of perf.orientated series, but doesn't offer any new features for itself. -Chris _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/intel-gfx
