A couple of small changes to simplify and restrict SVA APIs. The motivation
is to make PASID allocation palatable for cgroup consumptions. Misc cgroup
is merged for v5.13, it can be extended for IOASID as another scalar
resource.
I have not tested on ARM platforms due to availability. Would appreciate
if someone could help with the testing on ARM.
Thanks,
Jacob
ChangeLog:
V2
- retained mm argument in iommu_sva_alloc_pasid()
- keep generic supervisor flag separated from vt-d's SRE
- move flag declaration out of CONFIG_IOMMU_API
Jacob Pan (2):
iommu/sva: Tighten SVA bind API with explicit flags
iommu/sva: Remove mm parameter from SVA bind API
