Subject: [PATCH 0/5] KVM: arm64: pkvm; Rework aspects of the PSCI relay
Date: Sat, 21 Mar 2026 21:24:14 +0000 [thread overview]
Message-ID: <20260321212419.2803972-1-maz@kernel.org> (raw)
Having recently spent some quality time debugging [1], I ended up
reading too much of the PSCI relay code and felt that it could do with
a bit of spring cleaning.
To be clear, this series doesn't really fix anything. It simply adjust
things to my own taste, which may or may not be everyone's.
Comments appreciated,
Marc Zyngier (5):
KVM: arm64: pkvm: Move error handling to the end of kvm_hyp_cpu_entry
KVM: arm64: pkvm: Simplify BTI handling on CPU boot
KVM: arm64: pkvm: Turn __kvm_hyp_init_cpu into an inner label
KVM: arm64: pkvm: Use direct function pointers for cpu_{on,resume}
KVM: arm64: Remove extra ISBs when using msr_hcr_el2
