Subject: [patch 0/4] VMX: configure posted interrupt descriptor when assigning device (v4)
Date: Tue, 11 May 2021 20:57:38 -0300 [thread overview]
Message-ID: <20210511235738.333950860@redhat.com> (raw)
Configuration of the posted interrupt descriptor is incorrect when devices
are hotplugged to the guest (and vcpus are halted).
See patch 4 for details.
---
v4: remove NULL assignments from kvm_x86_ops (Peter Xu)
check for return value of ->start_assignment directly (Peter Xu)
v3: improved comments (Sean)
use kvm_vcpu_wake_up (Sean)
drop device_count from start_assignment function (Peter Xu)
v2: rather than using a potentially racy IPI (vs vcpu->cpu switches),
kick the vcpus when assigning a device and let the blocked per-CPU
list manipulation happen locally at ->pre_block and ->post_block
(Sean Christopherson).
