Just to confirm my understanding — are you suggesting that this issue should ideally be fixed in the RISC-V Kconfig (specifically the PORTABLE logic that ensures MMU is selected), rather than adding a local "depends on MMU" here in DRM_PIXPAPER? If that’s the case and the root cause will be addressed in the RISC-V side, I’m happy to drop this patch to avoid redundant dependencies. Best regards, LiangCheng
