Subject: [PATCH v11 00/19] KVM: xen: update shared_info and vcpu_info handling
Date: Tue, 19 Dec 2023 16:10:50 +0000 [thread overview]
Message-ID: <20231219161109.1318-1-paul@xen.org> (raw)
From: Paul Durrant <pdurrant@amazon.com>
This series has some small fixes from what was in version 10 [1]:
* KVM: pfncache: allow a cache to be activated with a fixed (userspace) HVA
This required a small fix to kvm_gpc_check() for an error that was
introduced in version 8.
* KVM: xen: separate initialization of shared_info cache and content
This accidentally regressed a fix in commit 5d6d6a7d7e66a ("KVM: x86:
Refine calculation of guest wall clock to use a single TSC read").
* KVM: xen: re-initialize shared_info if guest (32/64-bit) mode is set
This mistakenly removed the initialization of shared_info from the code
setting the KVM_XEN_ATTR_TYPE_SHARED_INFO attribute, which broke the self-
tests.
* KVM: xen: split up kvm_xen_set_evtchn_fast()
This had a /32 and a /64 swapped in set_vcpu_info_evtchn_pending().
