Subject: [PATCH kvmtool v3 00/17] aarch64: Handle PSCI calls in userspace
Date: Wed, 2 Aug 2023 23:42:38 +0000 [thread overview]
Message-ID: <20230802234255.466782-1-oliver.upton@linux.dev> (raw)
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@linux.dev/
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
