Subject: [PATCH 0/3] KVM: arm/arm64: Optimize lpi translation cache performance
Date: Wed, 24 Jul 2019 17:04:34 +0800 [thread overview]
Message-ID: <20190724090437.49952-1-xiexiangyou@huawei.com> (raw)
Hello,
This patches are based on Marc Zyngier's branch
https://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms.git/log/?h=kvm-arm64/its-translation-cache
As follows:
(1) Introduce multiple LPI translation caches to reduce concurrency
(2) Removed the unnecessary vgic_its_invalidate_cache()
(3) Introduced vgic_cpu->pending and vgic_cpu->lowest, reducing
vgic_cpu.ap_list_lock competition
Best Regards,
Xiangyou
