Subject: [PATCH kvmtool 00/21] arm64: Handle PSCI calls in userspace
Date: Fri, 26 May 2023 22:16:51 +0000 [thread overview]
Message-ID: <20230526221712.317287-1-oliver.upton@linux.dev> (raw)
The 6.4 kernel picks up support for a generalized SMCCC filter, allowing
userspace to select hypercall ranges that should be forwarded to
userspace. This is a shameless attempt of making future SMCCC interfaces
the responsibility of userspace :)
As a starting point, let's move PSCI up into userspace. KVM already
leans on userspace for handling calls that have a system-wide effect.
Tested on linux-next with a 64 vCPU VM. Additionally, I took a stab at
running kvm-unit-test's psci test, which passes.
Apologies for some of the changelogs being a bit short. It's Friday, and
I'm lazy.
Oliver Upton (21):
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: Add support for resetting a vCPU
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
