From 3a949f4c93548751a377691b2a208063da05e369 Mon Sep 17 00:00:00 2001 From: Gavin Shan Date: Tue, 30 Jun 2020 11:57:05 +1000 Subject: KVM: arm64: Rename HSR to ESR kvm/arm32 isn't supported since commit 541ad0150ca4 ("arm: Remove 32bit KVM host support"). So HSR isn't meaningful since then. This renames HSR to ESR accordingly. This shouldn't cause any functional changes: * Rename kvm_vcpu_get_hsr() to kvm_vcpu_get_esr() to make the function names self-explanatory. * Rename variables from @hsr to @esr to make them self-explanatory. Note that the renaming on uapi and tracepoint will cause ABI changes, which we should avoid. Specificly, there are 4 related source files in this regard: * arch/arm64/include/uapi/asm/kvm.h (struct kvm_debug_exit_arch::hsr) * arch/arm64/kvm/handle_exit.c (struct kvm_debug_exit_arch::hsr) * arch/arm64/kvm/trace_arm.h (tracepoints) * arch/arm64/kvm/trace_handle_exit.h (tracepoints) Signed-off-by: Gavin Shan Signed-off-by: Marc Zyngier Acked-by: Andrew Scull Link: https://lore.kernel.org/r/20200630015705.103366-1-gshan@redhat.com --- arch/arm64/include/asm/kvm_emulate.h | 34 +++++++++++++++++----------------- 1 file changed, 17 insertions(+), 17 deletions(-) (limited to 'arch/arm64/include/asm/kvm_emulate.h') diff --git a/arch/arm64/include/asm/kvm_emulate.h b/arch/arm64/include/asm/kvm_emulate.h index 4d0f8ea600ba..c9ba0df47f7d 100644 --- a/arch/arm64/include/asm/kvm_emulate.h +++ b/arch/arm64/include/asm/kvm_emulate.h @@ -259,14 +259,14 @@ static inline bool vcpu_mode_priv(const struct kvm_vcpu *vcpu) return mode != PSR_MODE_EL0t; } -static __always_inline u32 kvm_vcpu_get_hsr(const struct kvm_vcpu *vcpu) +static __always_inline u32 kvm_vcpu_get_esr(const struct kvm_vcpu *vcpu) { return vcpu->arch.fault.esr_el2; } static __always_inline int kvm_vcpu_get_condition(const struct kvm_vcpu *vcpu) { - u32 esr = kvm_vcpu_get_hsr(vcpu); + u32 esr = kvm_vcpu_get_esr(vcpu); if (esr & ESR_ELx_CV) return (esr & ESR_ELx_COND_MASK) >> ESR_ELx_COND_SHIFT; @@ -291,64 +291,64 @@ static inline u64 kvm_vcpu_get_disr(const struct kvm_vcpu *vcpu) static inline u32 kvm_vcpu_hvc_get_imm(const struct kvm_vcpu *vcpu) { - return kvm_vcpu_get_hsr(vcpu) & ESR_ELx_xVC_IMM_MASK; + return kvm_vcpu_get_esr(vcpu) & ESR_ELx_xVC_IMM_MASK; } static __always_inline bool kvm_vcpu_dabt_isvalid(const struct kvm_vcpu *vcpu) { - return !!(kvm_vcpu_get_hsr(vcpu) & ESR_ELx_ISV); + return !!(kvm_vcpu_get_esr(vcpu) & ESR_ELx_ISV); } static inline unsigned long kvm_vcpu_dabt_iss_nisv_sanitized(const struct kvm_vcpu *vcpu) { - return kvm_vcpu_get_hsr(vcpu) & (ESR_ELx_CM | ESR_ELx_WNR | ESR_ELx_FSC); + return kvm_vcpu_get_esr(vcpu) & (ESR_ELx_CM | ESR_ELx_WNR | ESR_ELx_FSC); } static inline bool kvm_vcpu_dabt_issext(const struct kvm_vcpu *vcpu) { - return !!(kvm_vcpu_get_hsr(vcpu) & ESR_ELx_SSE); + return !!(kvm_vcpu_get_esr(vcpu) & ESR_ELx_SSE); } static inline bool kvm_vcpu_dabt_issf(const struct kvm_vcpu *vcpu) { - return !!(kvm_vcpu_get_hsr(vcpu) & ESR_ELx_SF); + return !!(kvm_vcpu_get_esr(vcpu) & ESR_ELx_SF); } static __always_inline int kvm_vcpu_dabt_get_rd(const struct kvm_vcpu *vcpu) { - return (kvm_vcpu_get_hsr(vcpu) & ESR_ELx_SRT_MASK) >> ESR_ELx_SRT_SHIFT; + return (kvm_vcpu_get_esr(vcpu) & ESR_ELx_SRT_MASK) >> ESR_ELx_SRT_SHIFT; } static __always_inline bool kvm_vcpu_dabt_iss1tw(const struct kvm_vcpu *vcpu) { - return !!(kvm_vcpu_get_hsr(vcpu) & ESR_ELx_S1PTW); + return !!(kvm_vcpu_get_esr(vcpu) & ESR_ELx_S1PTW); } static __always_inline bool kvm_vcpu_dabt_iswrite(const struct kvm_vcpu *vcpu) { - return !!(kvm_vcpu_get_hsr(vcpu) & ESR_ELx_WNR) || + return !!(kvm_vcpu_get_esr(vcpu) & ESR_ELx_WNR) || kvm_vcpu_dabt_iss1tw(vcpu); /* AF/DBM update */ } static inline bool kvm_vcpu_dabt_is_cm(const struct kvm_vcpu *vcpu) { - return !!(kvm_vcpu_get_hsr(vcpu) & ESR_ELx_CM); + return !!(kvm_vcpu_get_esr(vcpu) & ESR_ELx_CM); } static __always_inline unsigned int kvm_vcpu_dabt_get_as(const struct kvm_vcpu *vcpu) { - return 1 << ((kvm_vcpu_get_hsr(vcpu) & ESR_ELx_SAS) >> ESR_ELx_SAS_SHIFT); + return 1 << ((kvm_vcpu_get_esr(vcpu) & ESR_ELx_SAS) >> ESR_ELx_SAS_SHIFT); } /* This one is not specific to Data Abort */ static __always_inline bool kvm_vcpu_trap_il_is32bit(const struct kvm_vcpu *vcpu) { - return !!(kvm_vcpu_get_hsr(vcpu) & ESR_ELx_IL); + return !!(kvm_vcpu_get_esr(vcpu) & ESR_ELx_IL); } static __always_inline u8 kvm_vcpu_trap_get_class(const struct kvm_vcpu *vcpu) { - return ESR_ELx_EC(kvm_vcpu_get_hsr(vcpu)); + return ESR_ELx_EC(kvm_vcpu_get_esr(vcpu)); } static inline bool kvm_vcpu_trap_is_iabt(const struct kvm_vcpu *vcpu) @@ -358,12 +358,12 @@ static inline bool kvm_vcpu_trap_is_iabt(const struct kvm_vcpu *vcpu) static __always_inline u8 kvm_vcpu_trap_get_fault(const struct kvm_vcpu *vcpu) { - return kvm_vcpu_get_hsr(vcpu) & ESR_ELx_FSC; + return kvm_vcpu_get_esr(vcpu) & ESR_ELx_FSC; } static __always_inline u8 kvm_vcpu_trap_get_fault_type(const struct kvm_vcpu *vcpu) { - return kvm_vcpu_get_hsr(vcpu) & ESR_ELx_FSC_TYPE; + return kvm_vcpu_get_esr(vcpu) & ESR_ELx_FSC_TYPE; } static __always_inline bool kvm_vcpu_dabt_isextabt(const struct kvm_vcpu *vcpu) @@ -387,7 +387,7 @@ static __always_inline bool kvm_vcpu_dabt_isextabt(const struct kvm_vcpu *vcpu) static __always_inline int kvm_vcpu_sys_get_rt(struct kvm_vcpu *vcpu) { - u32 esr = kvm_vcpu_get_hsr(vcpu); + u32 esr = kvm_vcpu_get_esr(vcpu); return ESR_ELx_SYS64_ISS_RT(esr); } -- cgit v1.2.3
