The performance improved slightly, but it still seems lower than the NXP driver. Here are some of the results: In screen (weston + DSI) test results: glmark2 command: glmark2-es2-wayland -b shading:duration=5.0 -b refract -b build -b texture -b shadow -b bump -s 640x480 2>&1 | | glmark2 tests | | sw ver |shading|build|texture|refract|shadow|bump| |-|---|-|---|---|--|| | etnaviv (no TS) | 263 | 334 | 291 | 22| 63 | 328| | etnaviv | 340 | 549 | 460 | 18| 84 | 560| | vivante | 544 | 956 | 790 | 26| 225 | 894| Enabling TS, etnaviv scores improved by around 30-60% compared to when it is disabled. However, it still remains approximately 40% lower than galcore.

This will prevent TS from being used, which has a large performance impact. But it shouldn't be necessary to disable it on the i.MX8MM GPU, as all memory accesses aside from the initial MMU commandstream go through MMU translation, so the issue with MC1.0 will not be hit. Can you try patching out the check in the kernel and see if it helps? I'll also send a proper patch for this.
