https://git.kernel.org/pub/scm/virt/kvm/kvm.git tags/for-linus for you to fetch changes up to 281106f938d3daaea6f8b6723a8217a2a1ef6936: selftests: kvm: set rax before vmcall (2022-08-01 08:43:05 -0400) Quite a large pull request due to a selftest API overhaul and some patches that had come in too late for 5.19. ---------------------------------------------------------------- ARM: * Unwinder implementations for both nVHE modes (classic and protected), complete with an overflow stack * Rework of the sysreg access from userspace, with a complete rewrite of the vgic-v3 view to allign with the rest of the infrastructure * Disagregation of the vcpu flags in separate sets to better track their use model. * A fix for the GICv2-on-v3 selftest * A small set of cosmetic fixes RISC-V: * Track ISA extensions used by Guest using bitmap * Added system instruction emulation framework * Added CSR emulation framework * Added gfp_custom flag in struct kvm_mmu_memory_cache * Added G-stage ioremap() and iounmap() functions * Added support for Svpbmt inside Guest s390: * add an interface to provide a hypervisor dump for secure guests * improve selftests to use TAP interface * enable interpretive execution of zPCI instructions (for PCI passthrough) * First part of deferred teardown * CPU Topology * PV attestation * Minor fixes x86: * Permit guests to ignore single-bit ECC errors * Intel IPI virtualization * Allow getting/setting pending triple fault with KVM_GET/SET_VCPU_EVENTS * PEBS virtualization * Simplify PMU emulation by just using PERF_TYPE_RAW events * More accurate event reinjection on SVM (avoid retrying instructions) * Allow getting/setting the state of the speaker port data bit * Refuse starting the kvm-intel module if VM-Entry/VM-Exit controls are inconsistent * "Notify" VM exit (detect microarchitectural hangs) for Intel * Use try_cmpxchg64 instead of cmpxchg64 * Ignore benign host accesses to PMU MSRs when PMU is disabled * Allow disabling KVM's "MONITOR/MWAIT are NOPs!" behavior * Allow NX huge page mitigation to be disabled on a per-vm basis * Port eager page splitting to shadow MMU as well * Enable CMCI capability by default and handle injected UCNA errors * Expose pid of vcpu threads in debugfs * x2AVIC support for AMD * cleanup PIO emulation * Fixes for LLDT/LTR emulation * Don't require refcounted "struct page" to create huge SPTEs * Miscellaneous cleanups: ** MCE MSR emulation ** Use separate namespaces for guest PTEs and shadow PTEs bitmasks ** PIO emulation ** Reorganize rmap API, mostly around rmap destruction ** Do not workaround very old KVM bugs for L0 that runs with nesting enabled ** new selftests API for CPUID Generic: * Fix races in gfn->pfn cache refresh; do not pin pages tracked by the cache * new selftests API using struct kvm_vcpu instead of a (vm, id) tuple ---------------------------------------------------------------- Andrei Vagin (1): selftests: kvm: set rax before vmcall Andrew Jones
