Re: [Qemu-devel] [PATCH 0/3] apic: ExtINT fixes for QNX

[Richard Bilson]

I've been testing these against our entire kernel regression suite. While they definitely fix the original problems, there is one test that now hangs. I'm going to have to get to the bottom of that failure before I can sign off.

Subject: [PATCH 0/3] apic: ExtINT fixes for QNX

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?

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
