Hi David, Compute contexts enable the compute power profile, and can use a different VM update mode from graphics contexts (SDMA vs. CPU). These differences are not going away. Not yet, anyway. If we start sharing VM address space between graphics and compute in the future, this will have to change. That is, these features would have to be controlled by other means than by the vm context.

After you merge kfd_vm to amdgpu_vm, does the difference still exist?

There are two patches in that series that touch amdgpu_vm.[ch] that I'd like your feedback on before I commit the changes to amd-kfd-staging and include them in my upstream patch series for KFD GPUVM support. See attached.
