Subject: Re: [PATCH] ehea: fix losing of NEQ events when one event occurred

From: Thadeu Lima de Souza Cascardo <>
Date: Thu, 10 May 2012 11:00:53 -0300

> The NEQ interrupt is only triggered when there was no previous pending
> interrupt. If we request irq handling after an interrupt has occurred,
> we will never get an interrupt until we call H_RESET_EVENTS.
> Events seem to be cleared when we first register the NEQ. So, when we
> requested irq handling right after registering it, a possible race with
> an interrupt was much less likely. Now, there is a chance we may lose
> this race and never get any events.
> The fix here is to poll and acknowledge any events that might have
> happened right after registering the irq handler.
