v2 of the series for doing PSCI calls in userspace. Changes since v1 [*]: - Avoid successive calls to KVM_ARM_VCPU_FINALIZE (Joey) - Clear the 'paused' state from calling vCPU in kvm_cpu__continue_vm() (Shaoqin) [*] https://lore.kernel.org/kvmarm/20230526221712.317287-1-oliver.upton@xxxxxxxxx/ Oliver Upton (20): update_headers: Use a list for arch-generic headers update_headers: Add missing entries to list of headers to copy Copy 64-bit alignment attrtibutes from Linux 6.4-rc1 Update headers with Linux 6.4-rc1 Import arm-smccc.h from Linux 6.4-rc1 aarch64: Copy cputype.h from Linux 6.4-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/kvm.h | 38 + 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/kvm.h | 55 +- include/linux/psci.h | 47 ++ include/linux/types.h | 13 + include/linux/vfio.h | 920 +++++++++++++++++++++- include/linux/vhost.h | 186 ++--- include/linux/virtio_blk.h | 105 +++ include/linux/virtio_net.h | 4 + kvm-cpu.c | 16 + riscv/include/asm/kvm.h | 3 + util/update_headers.sh | 25 +- x86/include/asm/kvm.h | 50 +- 31 files changed, 2213 insertions(+), 179 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: 3b1cdcf9e78f7d36f0cca805c4172bba53779b69 -- 2.41.0.162.gfafddb0af9-goog
