Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm

Pull x86 kvm updates from Paolo Bonzini:
"x86:

- KVM currently invalidates the entirety of the page tables, not just
those for the memslot being touched, when a memslot is moved or
deleted.

This does not traditionally have particularly noticeable overhead,
but Intel's TDX will require the guest to re-accept private pages
if they are dropped from the secure EPT, which is a non starter.

Actually, the only reason why this is not already being done is a
bug which was never fully investigated and caused VM instability
with assigned GeForce GPUs, so allow userspace to opt into the new
behavior.

- Advertise AVX10.1 to userspace (effectively prep work for the
"real" AVX10 functionality that is on the horizon)

- Rework common MSR handling code to suppress errors on userspace
accesses to unsupported-but-advertised MSRs

This will allow removing (almost?) all of KVM's exemptions for
userspace access to MSRs that shouldn't exist based on the vCPU
model (the actual cleanup is non-trivial future work)

- Rework KVM's handling of x2APIC ICR, again, because AMD (x2AVIC)
splits the 64-bit value into the legacy ICR and ICR2 storage,
whereas Intel (APICv) stores the entire 64-bit value at the ICR
offset

- Fix a bug where KVM would fail to exit to userspace if one was
triggered by a fastpath exit handler

- Add fastpath handling of HLT VM-Exit to expedite re-entering the
guest when there's already a pending wake event at the time of the
exit

- Fix a WARN caused by RSM entering a nested guest from SMM with
invalid guest state, by forcing the vCPU out of guest mode prior to
signalling SHUTDOWN (the SHUTDOWN hits the VM altogether, not the
nested guest)

- Overhaul the "unprotect and retry" logic to more precisely identify
cases where retrying is actually helpful, and to harden all retry
paths against putting the guest into an infinite retry loop

- Add support for yielding, e.g. to honor NEED_RESCHED, when zapping
rmaps in the shadow MMU

- Refactor pieces of the shadow MMU related to aging SPTEs in
prepartion for adding multi generation LRU support in KVM

- Don't stuff the RSB after VM-Exit when RETPOLINE=y and AutoIBRS is
enabled, i.e. when the CPU has already flushed the RSB

- Trace the per-CPU host save area as a VMCB pointer to improve
readability and cleanup the retrieval of the SEV-ES host save area

- Remove unnecessary accounting of temporary nested VMCB related
allocations

- Set FINAL/PAGE in the page fault error code for EPT violations if
and only if the GVA is valid. If the GVA is NOT valid, there is no
guest-side page table walk and so stuffing paging related metadata
is nonsensical

- Fix a bug where KVM would incorrectly synthesize a nested VM-Exit
instead of emulating posted interrupt delivery to L2

- Add a lockdep assertion to detect unsafe accesses of vmcs12
structures

- Harden eVMCS loading against an impossible NULL pointer deref
(really truly should be impossible)

- Minor SGX fix and a cleanup

- Misc cleanups

Generic:

- Register KVM's cpuhp and syscore callbacks when enabling
virtualization in hardware, as the sole purpose of said callbacks
is to disable and re-enable virtualization as needed

- Enable virtualization when KVM is loaded, not right before the
first VM is created

Together with the previous change, this simplifies a lot the logic
of the callbacks, because their very existence implies
virtualization is enabled

- Fix a bug that results in KVM prematurely exiting to userspace for
coalesced MMIO/PIO in many cases, clean up the related code, and
add a testcase

- Fix a bug in kvm_clear_guest() where it would trigger a buffer
overflow _if_ the gpa+len crosses a page boundary, which thankfully
is guaranteed to not happen in the current code base. Add WARNs in
more helpers that read/write guest memory to detect similar bugs

Selftests:

- Fix a goof that caused some Hyper-V tests to be skipped when run on
bare metal, i.e. NOT in a VM

- Add a regression test for KVM's handling of SHUTDOWN for an SEV-ES
guest

- Explicitly include one-off assets in .gitignore. Past Sean was
completely wrong about not being able to detect missing .gitignore
entries

- Verify userspace single-stepping works when KVM happens to handle a
VM-Exit in its fastpath

- Misc cleanups"

"ARM:

- Initial infrastructure for shadow stage-2 MMUs, as part of nested
virtualization enablement

- Support for userspace changes to the guest CTR_EL0 value, enabling
(in part) migration of VMs between heterogenous hardware

- Fixes + improvements to pKVM's FF-A proxy, adding support for v1.1
of the protocol

- FPSIMD/SVE support for nested, including merged trap configuration
and exception routing

- New command-line parameter to control the WFx trap behavior under
KVM

- Introduce kCFI hardening in the EL2 hypervisor

- Fixes + cleanups for handling presence/absence of FEAT_TCRX

- Miscellaneous fixes + documentation updates

LoongArch:

- Add perf kvm-stat support for loongarch

RISC-V:

- Redirect AMO load/store access fault traps to guest

- perf kvm stat support

- Use guest files for IMSIC virtualization, when available

s390:

- Assortment of tiny fixes which are not time critical

x86:

- Fixes for Xen emulation

- Add a global struct to consolidate tracking of host values, e.g.
EFER

- Add KVM_CAP_X86_APIC_BUS_CYCLES_NS to allow configuring the
effective APIC bus frequency, because TDX

- Print the name of the APICv/AVIC inhibits in the relevant
tracepoint

- Clean up KVM's handling of vendor specific emulation to
consistently act on "compatible with Intel/AMD", versus checking
for a specific vendor

- Drop MTRR virtualization, and instead always honor guest PAT on
CPUs that support self-snoop

- Update to the newfangled Intel CPU FMS infrastructure

- Don't advertise IA32_PERF_GLOBAL_OVF_CTRL as an MSR-to-be-saved, as
it reads '0' and writes from userspace are ignored

- Misc cleanups

x86 - MMU:

- Small cleanups, renames and refactoring extracted from the upcoming
Intel TDX support

- Don't allocate kvm_mmu_page.shadowed_translation for shadow pages
that can't hold leafs SPTEs

- Unconditionally drop mmu_lock when allocating TDP MMU page tables
for eager page splitting, to avoid stalling vCPUs when splitting
huge pages

- Bug the VM instead of simply warning if KVM tries to split a SPTE
that is non-present or not-huge. KVM is guaranteed to end up in a
broken state because the callers fully expect a valid SPTE, it's
all but dangerous to let more MMU changes happen afterwards

x86 - AMD:

- Make per-CPU save_area allocations NUMA-aware

- Force sev_es_host_save_area() to be inlined to avoid calling into
an instrumentable function from noinstr code

- Base support for running SEV-SNP guests. API-wise, this includes a
new KVM_X86_SNP_VM type, encrypting/measure the initial image into
guest memory, and finalizing it before launching it. Internally,
there are some gmem/mmu hooks needed to prepare gmem-allocated
pages before mapping them into guest private memory ranges

This includes basic support for attestation guest requests, enough
to say that KVM supports the GHCB 2.0 specification

There is no support yet for loading into the firmware those signing
keys to be used for attestation requests, and therefore no need yet
for the host to provide certificate data for those keys.

To support fetching certificate data from userspace, a new KVM exit
type will be needed to handle fetching the certificate from
userspace.

An attempt to define a new KVM_EXIT_COCO / KVM_EXIT_COCO_REQ_CERTS
exit type to handle this was introduced in v1 of this patchset, but
is still being discussed by community, so for now this patchset
only implements a stub version of SNP Extended Guest Requests that
does not provide certificate data

x86 - Intel:

- Remove an unnecessary EPT TLB flush when enabling hardware

- Fix a series of bugs that cause KVM to fail to detect nested
pending posted interrupts as valid wake eents for a vCPU executing
HLT in L2 (with HLT-exiting disable by L1)

- KVM: x86: Suppress MMIO that is triggered during task switch
emulation

Explicitly suppress userspace emulated MMIO exits that are
triggered when emulating a task switch as KVM doesn't support
userspace MMIO during complex (multi-step) emulation

Silently ignoring the exit request can result in the
WARN_ON_ONCE(vcpu->mmio_needed) firing if KVM exits to userspace
for some other reason prior to purging mmio_needed

See commit 0dc902267cb3 ("KVM: x86: Suppress pending MMIO write
exits if emulator detects exception") for more details on KVM's
limitations with respect to emulated MMIO during complex emulator
flows

Generic:

- Rename the AS_UNMOVABLE flag that was introduced for KVM to
AS_INACCESSIBLE, because the special casing needed by these pages
is not due to just unmovability (and in fact they are only
unmovable because the CPU cannot access them)

- New ioctl to populate the KVM page tables in advance, which is
useful to mitigate KVM page faults during guest boot or after live
migration. The code will also be used by TDX, but (probably) not
through the ioctl

- Enable halt poll shrinking by default, as Intel found it to be a
clear win

- Setup empty IRQ routing when creating a VM to avoid having to
synchronize SRCU when creating a split IRQCHIP on x86

- Rework the sched_in/out() paths to replace kvm_arch_sched_in() with
a flag that arch code can use for hooking both sched_in() and
sched_out()

- Take the vCPU @id as an "unsigned long" instead of "u32" to avoid
truncating a bogus value from userspace, e.g. to help userspace
detect bugs

- Mark a vCPU as preempted if and only if it's scheduled out while in
the KVM_RUN loop, e.g. to avoid marking it preempted and thus
writing guest memory when retrieving guest state during live
migration blackout

Selftests:

- Remove dead code in the memslot modification stress test

- Treat "branch instructions retired" as supported on all AMD Family
17h+ CPUs

- Print the guest pseudo-RNG seed only when it changes, to avoid
spamming the log for tests that create lots of VMs

- Make the PMU counters test less flaky when counting LLC cache
misses by doing CLFLUSH{OPT} in every loop iteration"

Replace all references to vcpu->run->immediate_exit with

malicious userspace could invoked KVM_RUN with immediate_exit=true and
then after KVM reads it to set wants_to_run=false, flip it to false.
This would result in the vCPU running in KVM_RUN with
wants_to_run=false. This wouldn't cause any real bugs today but is a

Now that KVM sets up empty irq routing in kvm_create_vm(), there's

Note, userspace could very theoretically use KVM_CREATE_IRQCHIP after
KVM_SET_GSI_ROUTING to reset to empty IRQ routing, but it's extremely
unlikely any VMM does that, e.g. the main reason s390 does anything for
KVM_CREATE_IRQCHIP is to that s390 doesn't need to be special cased by the
