For convenience, RMW-style accessors are also provided. - Multiple fixes for the so-called "arch-timer-edge-cases' selftest, which was always broken. x86: - Make KVM_PRE_FAULT_MEMORY stricter for TDX, allowing userspace to pass only the "untouched" addresses and flipping the shared/private bit in the implementation. - Disable SEV-SNP support on initialization failure ---------------------------------------------------------------- Ashish Kalra (1): KVM: SEV: Disable SEV-SNP support on initialization failure Marc Zyngier (4): KVM: arm64: Add assignment-specific sysreg accessor KVM: arm64: Add RMW specific sysreg accessor KVM: arm64: Don't use __vcpu_sys_reg() to get the address of a sysreg KVM: arm64: Make __vcpu_sys_reg() a pure rvalue operand Paolo Bonzini (3): Merge tag 'kvmarm-fixes-6.16-2' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD KVM: x86/mmu: Embed direct bits into gpa for KVM_PRE_FAULT_MEMORY KVM: x86/mmu: Reject direct bits in gpa passed to KVM_PRE_FAULT_MEMORY Sebastian Ott (4): KVM: arm64: selftests: Fix help text for arch_timer_edge_cases KVM: arm64: selftests: Fix thread migration in arch_timer_edge_cases KVM: arm64: selftests: Fix xVAL init in arch_timer_edge_cases KVM: arm64: selftests: Determine effective counter width in arch_timer_edge_cases arch/arm64/include/asm/kvm_host.h | 34 +++++++++--- arch/arm64/kvm/arch_timer.c | 18 +++---- arch/arm64/kvm/debug.c | 4 +- arch/arm64/kvm/fpsimd.c | 4 +- arch/arm64/kvm/hyp/exception.c | 4 +- arch/arm64/kvm/hyp/include/hyp/switch.h | 4 +- arch/arm64/kvm/hyp/include/hyp/sysreg-sr.h | 6 +-- arch/arm64/kvm/hyp/nvhe/hyp-main.c | 4 +- arch/arm64/kvm/hyp/vhe/switch.c | 4 +- arch/arm64/kvm/hyp/vhe/sysreg-sr.c | 46 ++++++++--------- arch/arm64/kvm/nested.c | 2 +- arch/arm64/kvm/pmu-emul.c | 24 ++++----- arch/arm64/kvm/sys_regs.c | 60 +++++++++++----------- arch/arm64/kvm/sys_regs.h | 4 +- arch/arm64/kvm/vgic/vgic-v3-nested.c | 10 ++-- arch/x86/kvm/mmu/mmu.c | 9 +++- arch/x86/kvm/svm/sev.c | 44 ++++++++++++---- .../selftests/kvm/arm64/arch_timer_edge_cases.c | 39 +++++++++----- 18 files changed, 194 insertions(+), 126 deletions(-)
