Subject: [GIT PULL] First batch of KVM changes for Linux 5.17
Linus,
The following changes since commit fdba608f15e2427419997b0898750a49a735afcb:
KVM: VMX: Wake vCPU when delivering posted IRQ even if vCPU == this vCPU (2021-12-21 12:39:03 -0500)
are available in the Git repository at:
https://git.kernel.org/pub/scm/virt/kvm/kvm.git tags/for-linus
for you to fetch changes up to c862dcd199759d4a45e65dab47b03e3e8a144e3a:
x86/fpu: Fix inline prefix warnings (2022-01-14 13:48:38 -0500)
----------------------------------------------------------------
RISCV:
- Use common KVM implementation of MMU memory caches
- SBI v0.2 support for Guest
- Initial KVM selftests support
- Fix to avoid spurious virtual interrupts after clearing hideleg CSR
- Update email address for Anup and Atish
ARM:
- Simplification of the 'vcpu first run' by integrating it into
KVM's 'pid change' flow
- Refactoring of the FP and SVE state tracking, also leading to
a simpler state and less shared data between EL1 and EL2 in
the nVHE case
- Tidy up the header file usage for the nvhe hyp object
- New HYP unsharing mechanism, finally allowing pages to be
unmapped from the Stage-1 EL2 page-tables
- Various pKVM cleanups around refcounting and sharing
- A couple of vgic fixes for bugs that would trigger once
the vcpu xarray rework is merged, but not sooner
- Add minimal support for ARMv8.7's PMU extension
- Rework kvm_pgtable initialisation ahead of the NV work
- New selftest for IRQ injection
- Teach selftests about the lack of default IPA space and
page sizes
- Expand sysreg selftest to deal with Pointer Authentication
- The usual bunch of cleanups and doc update
s390:
- fix sigp sense/start/stop/inconsistency
- cleanups
x86:
- Clean up some function prototypes more
- improved gfn_to_pfn_cache with proper invalidation, used by Xen emulation
- add KVM_IRQ_ROUTING_XEN_EVTCHN and event channel delivery
- completely remove potential TOC/TOU races in nested SVM consistency checks
- update some PMCs on emulated instructions
- Intel AMX support (joint work between Thomas and Intel)
- large MMU cleanups
- module parameter to disable PMU virtualization
- cleanup register cache
- first part of halt handling cleanups
- Hyper-V enlightened MSR bitmap support for nested hypervisors
Generic:
- clean up Makefiles
- introduce CONFIG_HAVE_KVM_DIRTY_RING
- optimize memslot lookup using a tree
- optimize vCPU array usage by converting to xarray
----------------------------------------------------------------
Two notes:
1) Despite the AMX commits having very new commit dates, they have been in
linux-next since before the merge window started. Borislav Petkov spotted
incomplete Signed-off-by chains that I only just got round to reconstruct
and fix. I'll check with other people if they have scripts to check this,
there ought to be some kind of commit hook in scripts/ that maintainers
can use.
2) A cleanup to the guest perf events came in through the tip tree.
Unfortunately, while I was aware of the series, I missed that it had
been accepted and therefore didn't ask Peter for a topic branch.
Therefore there will be a conflict in both arch/arm64 and arch/x86.
Not big but still a bit annoying. The resolution is kvm-5.17-conflict
on the https://git.kernel.org/pub/scm/virt/kvm/kvm.git tree.
and at the end of the message, but the gist of it is just this:
- if (in_pmi && !kvm_is_in_guest())
++ if (in_pmi && !kvm_handling_nmi_from_guest(pmc->vcpu))
+ irq_work_queue(&pmc_to_pmu(pmc)->irq_work);
+ else
+ kvm_make_request(KVM_REQ_PMI, pmc->vcpu);
Thanks,
Paolo
