* 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 -----BEGIN PGP SIGNATURE----- iQFIBAABCAAyFiEE8TM4V0tmI4mGbHaCv/vSX3jHroMFAmSgHrIUHHBib256aW5p QHJlZGhhdC5jb20ACgkQv/vSX3jHroORcAf+KkBlXwQMf+Q0Hy6Mfe0OtkKmh0Ae 6HJ6dsuMfOHhWv5kgukh+qvuGUGzHq+gpVKmZg2yP3h3cLHOLUAYMCDm+rjXyjsk F4DbnJLfxq43Pe9PHRKFxxSecRcRYCNox0GD5UYL4PLKcH0FyfQrV+HVBK+GI8L3 FDzUcyJkR12Lcj1qf++7fsbzfOshL0AJPmidQCoc6wkLJpUEr/nYUqlI1Kx3YNuQ LKmxFHS4l4/O/px3GKNDrLWDbrVlwciGIa3GZLS52PZdW3mAqT+cqcPcYK6SW71P m1vE80VbNELX5q3YSRoOXtedoZ3Pk97LEmz/xQAsJ/jri0Z5Syk0Ok0m/Q== =AMXp -----END PGP SIGNATURE----- Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm Pull kvm updates from Paolo Bonzini: "ARM64: - 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.
