Subject: [PATCH v1 0/3] KVM: VMX: Posted Interrupts fixes
Date: Wed, 6 Nov 2019 17:55:59 +0000 [thread overview]
Message-ID: <20191106175602.4515-1-joao.m.martins@oracle.com> (raw)
Hey,
This mini-series addresses two bugs plus a small cleanup:
1) Considering PID.PIR as opposed to just PID.ON for pending interrupt checks
in the direct yield code path;
2) Not changing NDST in vmx_vcpu_pi_load(), which addresses a regression.
Prior to this, we would observe Win2K12 guests hanging momentarily.
3) Small cleanup to streamline PIR checks with a common helper.
The cleanup is done last to simplify backports.
Joao
