Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvmPull kvm updates from Paolo Bonzini: "On top of a lot of Arm fixes, this includes a massive rename of types and variables in tools/testing/selftests/kvm - these were unnecessarily different from what the kernel uses, so they're being made consistent. arm64: - Allow tracing for non-pKVM, which was accidentally disabled when the series was merged - Rationalise the way the pKVM hypercall ranges are defined by using the same mechanism as already used for the vcpu_sysreg enum - Enforce that SMCCC function numbers relayed by the pKVM proxy are actually compliant with the specification - Fix a couple of feature to idreg mappings which resulted in the wrong sanitisation being applied - Fix the GICD_IIDR revision number field that could never been written correctly by userspace - Make kvm_vcpu_initialized() correctly use its parameter instead of relying on the surrounding context - Enforce correct ordering in __pkvm_init_vcpu(), plugging a potential pin leak at the same time - Move __pkvm_init_finalise() to a less dangerous spot, avoiding future problems - Restore functional userspace irqchip support after a four year breakage (last functional kernel was 5.18...) - Spelling fixes Selftests: - Rename types across all KVM selftests to more closely align with types used in the kernel: vm_vaddr_t -> gva_t vm_paddr_t -> gpa_t uint64_t -> u64 uint32_t -> u32 uint16_t -> u16 uint8_t -> u8 int64_t -> s64 int32_t -> s32 int16_t -> s16 int8_t -> s8 - Fix Loongarch compilation"* tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm: (31 commits) KVM: selftests: Add check_steal_time_uapi() implementation for LoongArch KVM: arm64: Wake-up from WFI when iqrchip is in userspace KVM: arm64: Fix initialisation order in __pkvm_init_finalise() KVM: arm64: Fix pin leak and publication ordering in __pkvm_init_vcpu() KVM: arm64: Fix kvm_vcpu_initialized() macro parameter KVM: arm64: Fix FEAT_SPE_FnE to use PMSIDR_EL1.FnE, not PMSVer KVM: arm64: Fix typo in feature check comments KVM: arm64: Fix FEAT_Debugv8p9 to check DebugVer, not PMUVer KVM: arm64: Reject non compliant SMCCC function calls in pKVM KVM: arm64: vgic: Fix IIDR revision field extracted from wrong value KVM: selftests: Replace "paddr" with "gpa" throughout KVM: selftests: Replace "u64 nested_paddr" with "gpa_t l2_gpa" KVM: selftests: Replace "u64 gpa" with "gpa_t" throughout KVM: selftests: Replace "vaddr" with "gva" throughout KVM: selftests: Clarify that arm64's inject_uer() takes a host PA, not a guest PA KVM: selftests: Rename translate_to_host_paddr() => translate_hva_to_hpa() KVM: selftests: Rename vm_vaddr_populate_bitmap() => vm_populate_gva_bitmap() KVM: selftests: Rename vm_vaddr_unused_gap() => vm_unused_gva_gap() KVM: selftests: Drop "vaddr_" from APIs that allocate memory for a given VM KVM: selftests: Use u8 instead of uint8_t ...

Merge tag 'kvm-x86-selftests_kernel_types-7.1' of https://github.com/kvm-x86/linux into HEADKVM selftests type renames for 7.1Renames types across all KVM selftests to more closely align with types usedin the kernel: vm_vaddr_t -> gva_t vm_paddr_t -> gpa_t uint64_t -> u64 uint32_t -> u32 uint16_t -> u16 uint8_t -> u8 int64_t -> s64 int32_t -> s32 int16_t -> s16 int8_t -> s8Using the kernel's preferred types eliminates a source of friction for manycontributors, as the majority of KVM selftests contributions come from kerneldevelopers. The kernel names are also shorter, which allows for more concisecode, and in any many cases eliminates newlines thanks to shorter types andparameter names.Rename variables and parameters as well as types, e.g. gpa instead of paddr,to again align with the kernel, and in a few cases to remove ambiguity, e.g.where paddr is used to refer to a _host_ physical address.

85819fa0e3b98682b8c57c6d8ba57e7a9c6032ea - KVM: selftests: Drop "vaddr_" from APIs that allocate memory for a given VM

Mon, 20 Apr 2026 23:19:56 +0200

KVM: selftests: Drop "vaddr_" from APIs that allocate memory for a given VMNow that KVM selftests use gva_t instead of vm_vaddr_t, drop "vaddr_" fromthe core memory allocation APIs as the information is extraneous and doesmore harm than good. E.g. the APIs don't _just_ allocate virtual memory,they allocate backing physical memory and install mappings in the guestpage tables. And as proven by kmalloc() and malloc(), developers generallyexpect that allocations come with a working virtual address.Opportunistically clean up the function comment for vm_alloc(), and dropthe misleading and superfluous comments for its wrappers.No functional change intended.Link: https://patch.msgid.link/20260420212004.3938325-12-seanjc@google.comSigned-off-by: Sean Christopherson List of files: /linux/tools/testing/selftests/kvm/x86/amx_test.c
