Subject: [GIT PULL] KVM/arm64 fixes for 6.12, take #1 From: Marc Zyngier To: Paolo Bonzini Cc: Catalin Marinas , Fuad Tabba , Joey Gouly , Mark Brown , Oliver Upton , Suzuki K Poulose , Vincent Donnefort , Will Deacon , Zenghui Yu , James Morse , linux-arm-kernel@lists.infradead.org, kvmarm@lists.linux.dev, kvm@vger.kernel.org Date: Thu, 3 Oct 2024 21:37:23 +0100 Paolo, Here's the first set of fixes for 6.12. We have fixes for a couple of pretty theoretical pKVM issues, plus a slightly more annoying fix for the feature detection infrastructure (details in the tag below). I expect to have a few more fixes in the coming weeks. Oh, and Joey is now an official reviewer, replacing James Please pull, M. The following changes since commit 9852d85ec9d492ebef56dc5f229416c925758edc: Linux 6.12-rc1 (2024-09-29 15:06:19 -0700) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm.git tags/kvmarm-fixes-6.12-1 for you to fetch changes up to a1d402abf8e3ff1d821e88993fc5331784fac0da: KVM: arm64: Fix kvm_has_feat*() handling of negative features (2024-10-03 19:35:27 +0100) ---------------------------------------------------------------- KVM/arm64 fixes for 6.12, take #1 - Fix pKVM error path on init, making sure we do not change critical system registers as we're about to fail - Make sure that the host's vector length is at capped by a value common to all CPUs - Fix kvm_has_feat*() handling of "negative" features, as the current code is pretty broken - Promote Joey to the status of official reviewer, while James steps down -- hopefully only temporarly ---------------------------------------------------------------- Marc Zyngier (2): KVM: arm64: Another reviewer reshuffle KVM: arm64: Fix kvm_has_feat*() handling of negative features Mark Brown (1): KVM: arm64: Constrain the host to the maximum shared SVE VL with pKVM Vincent Donnefort (1): KVM: arm64: Fix __pkvm_init_vcpu cptr_el2 error path MAINTAINERS | 2 +- arch/arm64/include/asm/kvm_host.h | 25 +++++++++++++------------ arch/arm64/kvm/hyp/include/hyp/switch.h | 2 +- arch/arm64/kvm/hyp/nvhe/hyp-main.c | 12 +++++++----- arch/arm64/kvm/hyp/nvhe/pkvm.c | 6 ++++-- 5 files changed, 26 insertions(+), 21 deletions(-) .
