Subject: Xen interrupts when using passthrough
Date: Tue, 4 Oct 2011 18:29:06 +0200	[thread overview]
Message-ID: <20111004162906.GA2681@mtldesk30> (raw)

Hi,
I am trying to debug a problem where a guest does not receive the
correct interrupt. It's a passtrough system where the guest is given a
virtual function and is using MSIX to recieve the interrupts. I am
trying to understand how is the guest supposed to recieve the
interrupt: Is it handled by dom0 which is using event channels to pass
the interrupt to domU, or is handled directly by domU. Please send
pointers to the code.

Thanks in advance,
eli;
