Subject: [PATCH v11 09/19] irqchip: gic: Add support for IPI FIQ
Date: Tue, 2 Sep 2014 14:00:43 +0100 [thread overview]
Message-ID: <1409662853-29313-10-git-send-email-daniel.thompson@linaro.org> (raw)
In-Reply-To: <1409662853-29313-1-git-send-email-daniel.thompson@linaro.org>
To support IPI FIQ we alter gic_cpu_init() to honour SMP_IPI_FIQ_MASK and
register a fairly high priority notifier to acknowledge and clear the IPI
when it is triggered.
For the IPI FIQ to be useful we must also make it safe to call
gic_raise_softirq() from the FIQ handler by altering the locking
strategy slightly.
