The put up as typical is extremely technical, so if you wish to full information give it a learn. The difficulty is with how Mesa was coping with the Vulkan Queue system, and what they had been doing initially gave the impression to be a little bit of an issue the place it was “splitting the batched submits into particular person ones, every submit additionally allocates a struct to comprise the submit information in order that the drivers can use the identical interface. So it’s rising the kernel overhead by performing a number of submits and in addition rising reminiscence allocations” with Blumenkrantz mentioning a number of exams that “showcase some driver ache factors”.
The result’s a pull request (not but merged) that offers a efficiency enchancment on RADV GFX11 (RDNA3) of 1000% in a single case and 50% in one other. A formidable win but it surely continues. On Lavapipe (a CPU-based Software program Vulkan driver) it noticed a 3000% enchancment in a single case and a 1000% enchancment in one other, Intel Arc (Intel DG2) one case noticed a 5000% enchancment and Turnip A740 had a 4000% enchancment and a 3000% enchancment for an additional level.
