[PATCH] Handle MSI irq storm
<<handle_msi_irq_storm.patch>> Hi, Keir,
This patch handles MSI irq storm. Unluckily, I have observed this
phenomenon again. This will happen when some kind of MSI-X capable NIC
is assigned to an HVM guest. The basic idea is to mask the interrupt on
receiving the second interrupt and set a timer to unmask after 1ms.
Can you have a look and give some comments on that? Thanks!
Best
