Subject: irq_work_run called from armv8pmu_handle_irq
Date: Wed, 01 Feb 2017 12:15:01 -0800 [thread overview]
Message-ID: <762e1210e12fbc693b3d0e27361df53f@codeaurora.org> (raw)
Hi All,
we would like to understand why irq_work_run() is getting called from
armv8pmu_handle_irq() irq handler for arm SoC.
Is this irq_work frame work designed to run works from ARMPMU irq
handlers? If there are no of drivers using the IRQ WORK frame work, we
may see that ARMPMU irq handler taking long time, right?
-Thanks, Prasad
