While tying to add support for the MSR_CORE_THREAD_COUNT MSR in KVM,
I realized that we were still in a world where user space has no control
over what happens with MSR emulation in KVM.
That is bad for multiple reasons. In my case, I wanted to emulate the
MSR in user space, because it's a CPU spe
Now that we have the ability to handle MSRs from user space and also to
select which ones we do want to prevent in-kernel KVM code from handling,
let's add a selftest to show case and verify the API.

It's not desireable to have all MSRs always handled by KVM kernel space. Some
MSRs would be useful to handle in user space to either emulate behavior (like
uCode updates) or differentiate whether they are valid based on the CPU model.
To allow user space to specify which MSRs it wants to see handl
MSRs are weird. Some of them are normal control registers, such as EFER.
Some however are registers that really are model specific, not very
interesting to virtualization workloads, and not performance critical.
Others again are really just windows into package configuration.

Dear friend,
I know this means of communication may not be morally right to you as
a person but I also have had a great thought about it and I have come
to this conclusion which I am about to share with you.

User APIs such as iommu_sva_unbind_gpasid() may also be used by the
kernel. Since we introduced user pointer to the UAPI functions,
in-kernel callers cannot share the same APIs. In-kernel callers are also

There can be multiple vendor-specific PASID data formats used in UAPI
structures. This patch adds enum type with a last entry which makes
range checking much easier.

IOMMU UAPI is newly introduced to support communications between guest
virtual IOMMU and host IOMMU. There has been lots of discussions on how
it should work with VFIO UAPI and userspace in general.
This document is intended to clarify the UAPI design and usage. The
mechanics of how future extensi
As IOMMU UAPI gets extended, user data size may increase. To support
backward compatibiliy, this patch introduces a size field to each UAPI
data structures. It is *always* the responsibility for the user to fill in
the correct size. Padding fields are adjusted to ensure 8 byte alignment.
Specific
IOMMU UAPI data size is filled by the user space which must be validated
by the kernel. To ensure backward compatibility, user data can only be
extended by either re-purpose padding bytes or extend the variable sized
union at the end. No size change is allowed before the union. Therefore,
the minim
IOMMU user APIs are responsible for processing user data. This patch
changes the interface such that user pointers can be passed into IOMMU
code directly. Separate kernel APIs without user pointers are introduced
for in-kernel users of the UAPI functionality.
IOMMU UAPI data has a user filled args
IOMMU user API header was introduced to support nested DMA translation and
related fault handling. The current UAPI data structures consist of three
areas that cover the interactions between host kernel and guest:
- fault handling
- cache invalidation
- bind guest page tables, i.e. guest PASID
IOMMU generic layer already does sanity checks UAPI data for version
match and argsz range under generic information.
Remove the redundant version check from VT-d driver and check for vendor
specific data size.
