Subject: [PATCH v3 0/3] x86/hvm: fix EFLAGS.IF handling of pending events with nested virt
Date: Thu, 12 Nov 2026 19:35:22 +0800 [thread overview]
Message-ID: <cover.1794482561.git.chunjie.zhu@citrix.com> (raw)
In-Reply-To: <ee9fbfcd-04d2-4e02-8f80-efb850289c30@citrix.com>
From: Chunjie Zhu <chunjie.zhu@citrix.com>
Patches 1 and 3 stop EFLAGS.IF from holding off NMI/#MC when nested state
is involved (and in hvm_interrupt_blocked() for #MC). Patch 2 makes
nested SVM honour L2's EFLAGS.IF when L1 clears V_INTR_MASKING.
v3:
* Address Ross's review comments on v2, see individual patches.
* New patch 3/3, suggested by Ross.
* Rebased on staging.
Chunjie Zhu (3):
x86/hvm: don't let EFLAGS.IF block NMI/#MC due to nested state
x86/nestedsvm: honour L2's EFLAGS.IF when L1 clears V_INTR_MASKING
x86/hvm: don't let EFLAGS.IF block #MC in hvm_interrupt_blocked
