Hi Paolo, Unfortunately work had me sidelined for an extended period of time, so after much delay here is a pile of fixes for 6.17. This is a bit larger than I would like, but the handling of on-CPU sysregs has had multiple ugly bugs and a localized fix would just be unnecessary churn. Details in the tag; please pull. Thanks, Oliver The following changes since commit 18ec25dd0e97653cdb576bb1750c31acf2513ea7: KVM: arm64: selftests: Add FEAT_RAS EL2 registers to get-reg-list (2025-07-28 08:28:05 -0700) are available in the Git repository at: https://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm.git/ tags/kvmarm-fixes-6.17-1 for you to fetch changes up to ee372e645178802be7cb35263de941db7b2c5354: KVM: arm64: nv: Fix ATS12 handling of single-stage translation (2025-08-28 12:44:42 -0700) ---------------------------------------------------------------- KVM/arm64 changes for 6.17, take #2 - Correctly handle 'invariant' system registers for protected VMs - Improved handling of VNCR data aborts, including external aborts - Fixes for handling of FEAT_RAS for NV guests, providing a sane fault context during SEA injection and preventing the use of RASv1p1 fault injection hardware - Ensure that page table destruction when a VM is destroyed gives an opportunity to reschedule - Large fix to KVM's infrastructure for managing guest context loaded on the CPU, addressing issues where the output of AT emulation doesn't get reflected to the guest - Fix AT S12 emulation to actually perform stage-2 translation when necessary - Avoid attempting vLPI irqbypass when GICv4 has been explicitly disabled for a VM - Minor KVM + selftest fixes ---------------------------------------------------------------- Arnd Bergmann (1): kvm: arm64: use BUG() instead of BUG_ON(1) Fuad Tabba (3): KVM: arm64: Handle AIDR_EL1 and REVIDR_EL1 in host for protected VMs KVM: arm64: Sync protected guest VBAR_EL1 on injecting an undef exception arm64: vgic-v2: Fix guest endianness check in hVHE mode Marc Zyngier (14): KVM: arm64: nv: Properly check ESR_EL2.VNCR on taking a VNCR_EL2 related fault KVM: arm64: selftest: Add standalone test checking for KVM's own UUID KVM: arm64: Correctly populate FAR_EL2 on nested SEA injection arm64: Add capability denoting FEAT_RASv1p1 KVM: arm64: Handle RASv1p1 registers KVM: arm64: Ignore HCR_EL2.FIEN set by L1 guest's EL2 KVM: arm64: Make ID_AA64PFR0_EL1.RAS writable KVM: arm64: Make ID_AA64PFR1_EL1.RAS_frac writable KVM: arm64: Get rid of ARM64_FEATURE_MASK() KVM: arm64: Check for SYSREGS_ON_CPU before accessing the 32bit state KVM: arm64: Simplify sysreg access on exception delivery KVM: arm64: Fix vcpu_{read,write}_sys_reg() accessors KVM: arm64: Remove __vcpu_{read,write}_sys_reg_{from,to}_cpu() KVM: arm64: nv: Fix ATS12 handling of single-stage translation Mark Brown (1): KVM: arm64: selftests: Sync ID_AA64MMFR3_EL1 in set_id_regs Oliver Upton (1): KVM: arm64: nv: Handle SEAs due to VNCR redirection Raghavendra Rao Ananta (3): KVM: arm64: Don't attempt vLPI mappings when vPE allocation is disabled KVM: arm64: Split kvm_pgtable_stage2_destroy() KVM: arm64: Reschedule as needed when destroying the stage-2 page-tables arch/arm64/include/asm/kvm_host.h | 111 +----- arch/arm64/include/asm/kvm_mmu.h | 1 + arch/arm64/include/asm/kvm_pgtable.h | 30 ++ arch/arm64/include/asm/kvm_pkvm.h | 4 +- arch/arm64/include/asm/kvm_ras.h | 25 -- arch/arm64/include/asm/sysreg.h | 3 - arch/arm64/kernel/cpufeature.c | 24 ++ arch/arm64/kvm/arm.c | 8 +- arch/arm64/kvm/at.c | 6 +- arch/arm64/kvm/emulate-nested.c | 2 +- arch/arm64/kvm/hyp/exception.c | 20 +- arch/arm64/kvm/hyp/nvhe/list_debug.c | 2 +- arch/arm64/kvm/hyp/nvhe/sys_regs.c | 5 + arch/arm64/kvm/hyp/pgtable.c | 25 +- arch/arm64/kvm/hyp/vgic-v2-cpuif-proxy.c | 2 +- arch/arm64/kvm/hyp/vhe/switch.c | 5 +- arch/arm64/kvm/mmu.c | 65 +++- arch/arm64/kvm/nested.c | 5 +- arch/arm64/kvm/pkvm.c | 11 +- arch/arm64/kvm/sys_regs.c | 419 ++++++++++++++------- arch/arm64/kvm/vgic/vgic-mmio-v3.c | 8 + arch/arm64/kvm/vgic/vgic-mmio.c | 2 +- arch/arm64/kvm/vgic/vgic.h | 10 +- arch/arm64/tools/cpucaps | 1 + tools/arch/arm64/include/asm/sysreg.h | 3 - tools/testing/selftests/kvm/Makefile.kvm | 1 + .../testing/selftests/kvm/arm64/aarch32_id_regs.c | 2 +- .../testing/selftests/kvm/arm64/debug-exceptions.c | 12 +- tools/testing/selftests/kvm/arm64/kvm-uuid.c | 70 ++++ tools/testing/selftests/kvm/arm64/no-vgic-v3.c | 4 +- .../testing/selftests/kvm/arm64/page_fault_test.c | 6 +- tools/testing/selftests/kvm/arm64/set_id_regs.c | 9 +- .../selftests/kvm/arm64/vpmu_counter_access.c | 2 +- tools/testing/selftests/kvm/lib/arm64/processor.c | 6 +- 34 files changed, 560 insertions(+), 349 deletions(-) delete mode 100644 arch/arm64/include/asm/kvm_ras.h create mode 100644 tools/testing/selftests/kvm/arm64/kvm-uuid.c
