I'm writing the patch set to define pasid as "unsigned int" consistently in iommu. I'll put the amdkfd changes (only a few changes including this pasid change in struct kfd_processin) one patch and send it to you for review. -Fenghua _______________________________________________ amd-gfx mailing list amd-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/amd-gfx
