The fix is bogus since assertion of a GSI (basically an IO-APIC input pin) should not be dependent on whether the pin is masked in the IO-APIC -- the input pin 'voltage level' is obviously not affected by the masked/not-masked. This is *supposed* to just work (assuming it is the PV-on-HVM IRQ that is getting stuck asserted). See the explicit logic to deassert and then reassert the PV-on-HVM INTx line in irq_save_pci(). My guess would be that you are using 3.1 branch, where that fix was never applied (not sure why; possibly I missed it by accident). You want changeset 15691 from xen-unstable.hg. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
