After enabling SysMMU I've switched to other Exynos tasks, not related to graphics. FWIW, I've implemented the test driver for SysMMU, which you can use to verify your SysMMU driver is functional. It's able to perform address translations initiated from the test driver (using regular CPU). That way you can test your SysMMU without DPU or other IP blocks initiating the translation. You can find SysMMU test driver in GitHub repo [1], and the commit adding the driver is [2]. All that said, I'd be excited to see DRM working on Exynos850 some day! So please keep me in the loop, and let me know if I can help somehow (by testing the code, etc). Thanks!
