* Eager page splitting optimization for dirty logging, optionally
allowing for a VM to avoid the cost of hugepage splitting in the stage-2
fault path.
* Arm FF-A proxy for pKVM, allowing a pKVM host to safely interact with
services that live in the Secure world. pKVM intervenes on FF-A calls
to guarantee the host doesn't misuse memory donated to the hyp or a
pKVM guest.
* Support for running the split hypervisor with VHE enabled, known as
'hVHE' mode. This is extremely useful for testing the split
hypervisor on VHE-only systems, and paves the way for new use cases
that depend on having two TTBRs available at EL2.
* Generalized framework for configurable ID registers from userspace.
KVM/arm64 currently prevents arbitrary CPU feature set configuration
from userspace, but the intent is to relax this limitation and allow
userspace to select a feature set consistent with the CPU.
* Enable the use of Branch Target Identification (FEAT_BTI) in the
hypervisor.
* Use a separate set of pointer authentication keys for the hypervisor
when running in protected mode, as the host is untrusted at runtime.
* Ensure timer IRQs are consistently released in the init failure
paths.
* Avoid trapping CTR_EL0 on systems with Enhanced Virtualization Traps
(FEAT_EVT), as it is a register commonly read from userspace.
* Erratum workaround for the upcoming AmpereOne part, which has broken
hardware A/D state management.
RISC-V:
* Redirect AMO load/store misaligned traps to KVM guest
* Trap-n-emulate AIA in-kernel irqchip for KVM guest
* Svnapot support for KVM Guest
s390:
* New uvdevice secret API
* CMM selftest and fixes
* fix racy access to target CPU for diag 9c
x86:
* Fix missing/incorrect #GP checks on ENCLS
* Use standard mmu_notifier hooks for handling APIC access page
* Drop now unnecessary TR/TSS load after VM-Exit on AMD
* Print more descriptive information about the status of SEV and SEV-ES during
module load
* Add a test for splitting and reconstituting hugepages during and after
dirty logging
* Add support for CPU pinning in demand paging test
* Add support for AMD PerfMonV2, with a variety of cleanups and minor fixes
included along the way
* Add a "nx_huge_pages=never" option to effectively avoid creating NX hugepage
recovery threads (because nx_huge_pages=off can be toggled at runtime)
* Move handling of PAT out of MTRR code and dedup SVM+VMX code
* Fix output of PIC poll command emulation when there's an interrupt
* Add a maintainer's handbook to document KVM x86 processes, preferred coding
style, testing expectations, etc.
* Misc cleanups, fixes and comments
Generic:
* Miscellaneous bugfixes and cleanups
Selftests:
* Generate dependency files so that partial rebuilds work as expected
