Hi, Yong,
In commit: 6027b1bf6071fc61a5aa11b9922a2e0e91bff1ea
drm/amdkfd: Use hex print format for pasid
pasid's type was change to "uint16_t" from "unsigned int" in
struct kfd_process.
But, pasid is a 20-bit value according to PCIe spec and other places
in amdkfd (plus other iommu code) define pasid as "unsigned int".
If defined as uint16_t, pasid will overflow if its value is bigger than 16-bit.
Did I miss anything? Should we change pasid's type back to "unsigned int"?
[a little background: pasid is defined as various types including "int",
"unsigned int", "u32" in iommu. I'm changing pasid's types to "unsigned int"
so that the types are consistent in iommu]
Thanks.
-Fenghua
