KVM nested SVM changes for 7.1 (with one common x86 fix) - To minimize the probability of corrupting guest state, defer KVM's non-architectural delivery of exception payloads (e.g. CR2 and DR6) until consumption of the payload is imminent, and force delivery of the payload in all paths where userspace saves relevant state. - Use vcpu->arch.cr2 when updating vmcb12's CR2 on nested #VMEXIT to fix a bug where L2's CR2 can get corrupted after a save/restore, e.g. if the VM is migrated while L2 is faulting in memory. - Fix a class of nSVM bugs where some fields written by the CPU are not synchronized from vmcb02 to cached vmcb12 after VMRUN, and so are not up-to-date when saved by KVM_GET_NESTED_STATE. - Fix a class of bugs where the ordering between KVM_SET_NESTED_STATE and KVM_SET_{S}REGS could cause vmcb02 to be incorrectly initialized after save+restore. - Add a variety of missing nSVM consistency checks. - Fix several bugs where KVM failed to correctly update VMCB fields on nested #VMEXIT. - Fix several bugs where KVM failed to correctly synthesize #UD or #GP for SVM-related instructions. - Add support for save+restore of virtualized LBRs (on SVM). - Refactor various helpers and macros to improve clarity and (hopefully) make the code easier to maintain. - Aggressively sanitize fields when copying from vmcb12 to guard against unintentionally allowing L1 to utilize yet-to-be-defined features. - Fix several bugs where KVM botched rAX legality checks when emulating SVM instructions. Note, KVM is still flawed in that KVM doesn't address size prefix overrides for 64-bit guests; this should probably be documented as a KVM erratum. - Fail emulation of VMRUN/VMLOAD/VMSAVE if mapping vmcb12 fails instead of somewhat arbitrarily synthesizing #GP (i.e. don't bastardize AMD's already- sketchy behavior of generating #GP if for "unsupported" addresses). - Cache all used vmcb12 fields to further harden against TOCTOU bugs.

Merge tag 'kvmarm-7.1' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD

KVM/arm64 updates for 7.1 * New features: - Add support for tracing in the standalone EL2 hypervisor code, which should help both debugging and performance analysis. This comes with a full infrastructure for 'remote' trace buffers that can be exposed by non-kernel entities such as firmware. - Add support for GICv5 Per Processor Interrupts (PPIs), as the starting point for supporting the new GIC architecture in KVM. - Finally add support for pKVM protected guests, with anonymous memory being used as a backing store. About time! * Improvements and bug fixes: - Rework the dreaded user_mem_abort() function to make it more maintainable, reducing the amount of state being exposed to the various helpers and rendering a substantial amount of state immutable. - Expand the Stage-2 page table dumper to support NV shadow page tables on a per-VM basis. - Tidy up the pKVM PSCI proxy code to be slightly less hard to follow. - Fix both SPE and TRBE in non-VHE configurations so that they do not generate spurious, out of context table walks that ultimately lead to very bad HW lockups. - A small set of patches fixing the Stage-2 MMU freeing in error cases. - Tighten-up accepted SMC immediate value to be only #0 for host SMCCC calls. - The usual cleanups and other selftest churn.

KVM: LoongArch: selftests: Add basic PMU event counting test

2026-04-09T10:56:37+00:00

Introduce a basic PMU test that verifies hardware event counting for four performance counters. The test enables the events for CPU cycles, instructions retired, branch instructions, and branch misses, runs a fixed number of loops, and checks that the counter values fall within expected ranges. It also validates that the host supports PMU and that the VM feature is enabled. Signed-off-by: Song Gao Signed-off-by: Huacai Chen

KVM: s390: selftests: enable some common memory-related tests

2026-04-07T15:20:30+00:00

Enable the following tests on s390: * memslot_modification_stress_test * memslot_perf_test * mmu_stress_test Since the first two tests are now supported on all architectures, move them into TEST_GEN_PROGS_COMMON and out of the indiviual architectures.

KVM: arm64: selftests: Add no-vgic-v5 selftest

2026-03-19T18:21:29+00:00

Now that GICv5 is supported, it is important to check that all of the GICv5 register state is hidden from a guest that doesn't create a vGICv5. Rename the no-vgic-v3 selftest to no-vgic, and extend it to check GICv5 system registers too.

KVM: arm64: selftests: Introduce a minimal GICv5 PPI selftest

2026-03-19T18:21:29+00:00

This basic selftest creates a vgic_v5 device (if supported), and tests that one of the PPI interrupts works as expected with a basic single-vCPU guest. Upon starting, the guest enables interrupts. That means that it is initialising all PPIs to have reasonable priorities, but marking them as disabled. Then the priority mask in the ICC_PCR_EL1 is set, and interrupts are enable in ICC_CR0_EL1. At this stage the guest is able to receive interrupts. The architected SW_PPI (64) is enabled and KVM_IRQ_LINE ioctl is used to inject the state into the guest. The guest's interrupt handler has an explicit WFI in order to ensure that the guest skips WFI when there are pending and enabled PPI interrupts.
