[PATCH] ASoC: fsl_ssi: Provide register I/O functions by default

by Mark Brown

From: Mark Brown <broonie(a)linaro.org> Use the ARM version by default as that's the more generally portable one, it doesn't matter if they work well on random platforms when the goal is only build coverage.

[PATCH V3] arm64: KVM: Support X-Gene guest VCPU on APM X-Gene host

by Anup Patel

This patch allows us to have X-Gene guest VCPU when using KVM arm64 on APM X-Gene host. We add KVM_ARM_TARGET_XGENE_POTENZA for X-Gene Potenza compatible guest VCPU and we return KVM_ARM_TARGET_XGENE_POTENZA in kvm_target_cpu() when running on X-Gene host with Potenza core. V3: - Reduce multiple "return -EINVAL" in kvm_target_cpu() V2: - Renamed KVM_ARM_TARGET_XGENE_V8 to KVM_ARM_TARGET_XGENE_POTENZA V1: - Initial patch with target named as KVM_ARM_TARGET_XGENE_V8 Signed-off-by: Anup Patel <anup.patel(a)linaro.org> Signed-off-by: Pranavkumar Sawargaonkar <pranavkumar(a)linaro.org> --- arch/arm64/include/uapi/asm/kvm.h | 3 ++- arch/arm64/kvm/guest.c | 36 ++++++++++++++++++++++------------ arch/arm64/kvm/sys_regs_generic_v8.c | 3 +++ 3 files changed, 29 insertions(+), 13 deletions(-) diff --git a/arch/arm64/include/uapi/asm/kvm.h b/arch/arm64/include/uapi/asm/kvm.h index 5031f42..d9f026b 100644 --- a/arch/arm64/include/uapi/asm/kvm.h +++ b/arch/arm64/include/uapi/asm/kvm.h @@ -55,8 +55,9 @@ struct kvm_regs { #define KVM_ARM_TARGET_AEM_V8 0 #define KVM_ARM_TARGET_FOUNDATION_V8 1 #define KVM_ARM_TARGET_CORTEX_A57 2 +#define KVM_ARM_TARGET_XGENE_POTENZA 3 -#define KVM_ARM_NUM_TARGETS 3 +#define KVM_ARM_NUM_TARGETS 4 /* KVM_ARM_SET_DEVICE_ADDR ioctl id encoding */ #define KVM_ARM_DEVICE_TYPE_SHIFT 0 diff --git a/arch/arm64/kvm/guest.c b/arch/arm64/kvm/guest.c index 2c3ff67..143d179 100644 --- a/arch/arm64/kvm/guest.c +++ b/arch/arm64/kvm/guest.c @@ -207,20 +207,32 @@ int __attribute_const__ kvm_target_cpu(void) unsigned long implementor = read_cpuid_implementor(); unsigned long part_number = read_cpuid_part_number(); - if (implementor != ARM_CPU_IMP_ARM) - return -EINVAL; - - switch (part_number) { - case ARM_CPU_PART_AEM_V8: - return KVM_ARM_TARGET_AEM_V8; - case ARM_CPU_PART_FOUNDATION: - return KVM_ARM_TARGET_FOUNDATION_V8; - case ARM_CPU_PART_CORTEX_A57: - /* Currently handled by the generic backend */ - return KVM_ARM_TARGET_CORTEX_A57; + switch (implementor) { + case ARM_CPU_IMP_ARM: + switch (part_number) { + case ARM_CPU_PART_AEM_V8: + return KVM_ARM_TARGET_AEM_V8; + case ARM_CPU_PART_FOUNDATION: + return KVM_ARM_TARGET_FOUNDATION_V8; + case ARM_CPU_PART_CORTEX_A57: + return KVM_ARM_TARGET_CORTEX_A57; + default: + break; + } + break; + case ARM_CPU_IMP_APM: + switch (part_number) { + case APM_CPU_PART_POTENZA: + return KVM_ARM_TARGET_XGENE_POTENZA; + default: + break; + } + break; default: - return -EINVAL; + break; } + + return -EINVAL; } int kvm_vcpu_set_target(struct kvm_vcpu *vcpu, diff --git a/arch/arm64/kvm/sys_regs_generic_v8.c b/arch/arm64/kvm/sys_regs_generic_v8.c index 4268ab9..8fe6f76 100644 --- a/arch/arm64/kvm/sys_regs_generic_v8.c +++ b/arch/arm64/kvm/sys_regs_generic_v8.c @@ -90,6 +90,9 @@ static int __init sys_reg_genericv8_init(void) &genericv8_target_table); kvm_register_target_sys_reg_table(KVM_ARM_TARGET_CORTEX_A57, &genericv8_target_table); + kvm_register_target_sys_reg_table(KVM_ARM_TARGET_XGENE_POTENZA, + &genericv8_target_table); + return 0; } late_initcall(sys_reg_genericv8_init); -- 1.7.9.5
