v3 of the series to do PSCI calls in userspace, as an example for using the SMCCC filtering API added to KVM in 6.4. v2 -> v3: - Dropped some of the headers patches since they've already been updated - Redo header imports on top of 6.5-rc1 - Actually use the right subject prefix... v2: https://lore.kernel.org/kvmarm/20230620163353.2688567-1-oliver.upton@xxxxxxxxx/ Oliver Upton (17): Import arm-smccc.h from Linux 6.5-rc1 aarch64: Copy cputype.h from Linux 6.5-rc1 Update psci.h to Linux 6.5-rc1 arm: Stash kvm_vcpu_init for later use arm: Use KVM_SET_MP_STATE ioctl to power off non-boot vCPUs aarch64: Expose ARM64_CORE_REG() for general use arm: Generalize execution state specific VM initialization Add helpers to pause the VM from vCPU thread aarch64: Add support for finding vCPU for given MPIDR aarch64: Add skeleton implementation for PSCI aarch64: psci: Implement CPU_SUSPEND aarch64: psci: Implement CPU_OFF aarch64: psci: Implement CPU_ON aarch64: psci: Implement AFFINITY_INFO aarch64: psci: Implement MIGRATE_INFO_TYPE aarch64: psci: Implement SYSTEM_{OFF,RESET} aarch64: smccc: Start sending PSCI to userspace Makefile | 4 +- arm/aarch32/include/kvm/kvm-arch.h | 2 +- arm/aarch32/kvm-cpu.c | 5 + arm/aarch64/include/asm/cputype.h | 186 +++++++++++++++++ arm/aarch64/include/asm/smccc.h | 65 ++++++ arm/aarch64/include/kvm/kvm-arch.h | 2 +- arm/aarch64/include/kvm/kvm-config-arch.h | 6 +- arm/aarch64/include/kvm/kvm-cpu-arch.h | 28 ++- arm/aarch64/kvm-cpu.c | 48 +++-- arm/aarch64/kvm.c | 25 ++- arm/aarch64/psci.c | 207 +++++++++++++++++++ arm/aarch64/smccc.c | 81 ++++++++ arm/include/arm-common/kvm-arch.h | 2 + arm/include/arm-common/kvm-config-arch.h | 1 + arm/include/arm-common/kvm-cpu-arch.h | 2 +- arm/kvm-cpu.c | 21 +- arm/kvm.c | 2 +- include/kvm/kvm-cpu.h | 3 + include/linux/arm-smccc.h | 240 ++++++++++++++++++++++ include/linux/psci.h | 47 +++++ kvm-cpu.c | 16 ++ 21 files changed, 959 insertions(+), 34 deletions(-) create mode 100644 arm/aarch64/include/asm/cputype.h create mode 100644 arm/aarch64/include/asm/smccc.h create mode 100644 arm/aarch64/psci.c create mode 100644 arm/aarch64/smccc.c create mode 100644 include/linux/arm-smccc.h base-commit: 106e2ea7756d980454d68631b87d5e25ba4e4881 -- 2.41.0.585.gd2178a4bd4-goog
