The generic header files can't meet the goal. This duplicate the generic header files to be our platform specific header files. It's the preparatory work to support the asynchronous page fault in the subsequent patches: include/uapi/asm-generic/kvm_para.h include/asm-generic/kvm_para.h arch/arm64/include/uapi/asm/kvm_para.h arch/arm64/include/asm/kvm_para.h Signed-off-by: Gavin Shan --- arch/arm64/include/asm/kvm_para.h | 27 ++++++++++++++++++++++++++ arch/arm64/include/uapi/asm/Kbuild | 2 -- arch/arm64/include/uapi/asm/kvm_para.h | 5 +++++ 3 files changed, 32 insertions(+), 2 deletions(-) create mode 100644 arch/arm64/include/asm/kvm_para.h create mode 100644 arch/arm64/include/uapi/asm/kvm_para.h diff --git a/arch/arm64/include/asm/kvm_para.h b/arch/arm64/include/asm/kvm_para.h new file mode 100644 index 000000000000..0ea481dd1c7a --- /dev/null +++ b/arch/arm64/include/asm/kvm_para.h @@ -0,0 +1,27 @@ +/* SPDX-License-Identifier: GPL-2.0 */ +#ifndef _ASM_ARM_KVM_PARA_H +#define _ASM_ARM_KVM_PARA_H + +#include + +static inline bool kvm_check_and_clear_guest_paused(void) +{ + return false; +} + +static inline unsigned int kvm_arch_para_features(void) +{ + return 0; +} + +static inline unsigned int kvm_arch_para_hints(void) +{ + return 0; +} + +static inline bool kvm_para_available(void) +{ + return false; +} + +#endif /* _ASM_ARM_KVM_PARA_H */ diff --git a/arch/arm64/include/uapi/asm/Kbuild b/arch/arm64/include/uapi/asm/Kbuild index 602d137932dc..f66554cd5c45 100644 --- a/arch/arm64/include/uapi/asm/Kbuild +++ b/arch/arm64/include/uapi/asm/Kbuild @@ -1,3 +1 @@ # SPDX-License-Identifier: GPL-2.0 - -generic-y += kvm_para.h diff --git a/arch/arm64/include/uapi/asm/kvm_para.h b/arch/arm64/include/uapi/asm/kvm_para.h new file mode 100644 index 000000000000..cd212282b90c --- /dev/null +++ b/arch/arm64/include/uapi/asm/kvm_para.h @@ -0,0 +1,5 @@ +/* SPDX-License-Identifier: GPL-2.0 WITH Linux-syscall-note */ +#ifndef _UAPI_ASM_ARM_KVM_PARA_H +#define _UAPI_ASM_ARM_KVM_PARA_H + +#endif /* _UAPI_ASM_ARM_KVM_PARA_H */ -- 2.23.0 _______________________________________________ kvmarm mailing list kvmarm@lists.cs.columbia.edu https://lists.cs.columbia.edu/mailman/listinfo/kvmarm
