Subject: [Qemu-devel] [PATCH 0/3] apic: ExtINT fixes for QNX
Date: Tue, 11 Nov 2014 15:23:18 +0100 [thread overview]
Message-ID: <1415715801-30782-1-git-send-email-pbonzini@redhat.com> (raw)
Richard Bilson reported some QNX emulation bugs. I sent him offlist a
prototype patch, that he commented on.
The first patch here works around what is arguably a QNX bug, that is
triggered by the last two patches; but it is better to avoid spurious
HLT wakeups, so here it is. The last two patches are what Richard
had tested, amended with a fix for Windows XP + KVM + QEMU apic.
Richard, can you confirm that these patches work?
Paolo

apic: avoid getting out of halted state on masked PIC interrupts
apic: fix loss of IPI due to masked ExtINT
apic: fix incorrect handling of ExtINT interrupts wrt processor
priority
