Subject: [PATCH v3 0/4] Improve dirty ring warning report
Date: Fri, 27 Jan 2023 07:54:47 +0800	[thread overview]
Message-ID: <20230126235451.469087-1-gshan@redhat.com> (raw)

It has been known case where no running VCPU context exists when the
vgic/its tables are saved. There are other two unknown cases where we
don't have the running VCPU context: (a) restore vgic3 LPI pending
status. (b) restoring vgic3 pending tables.

PATCH[1]     includes 'kvm_mmu.h' to 'vgic.h'
PATCH[2]     adds unified helper vgic_write_guest_lock()
PATCH[3 - 4] allows no-running-vcpu context for (a) and (b)

v2: https://lore.kernel.org/kvmarm/Y9Lg1ESUVJov0WpH@google.com/T/#t
v1: https://lore.kernel.org/kvmarm/20230116040405.260935-1-gshan@redhat.com/T/#t

Changelog
=========
v3:
  * Pick Oliver's r-bs
  * Include 'kvm_mmu.h' to 'vgic.h'                            (Oliver)
v2:
  * Add unified helper vgic_write_guest_lock()                 (Oliver)
  * Dropped two patches to refactor mark_page_dirty_in_slot()  (Sean)
