Subject: Realtime interrupt handling in driver
Date: Wed, 23 Feb 2022 00:10:15 +0000 [thread overview]
Message-ID: <PH1P110MB1050BF72127DFC0CE3440B64E23C9@PH1P110MB1050.NAMP110.PROD.OUTLOOK.COM> (raw)
Hello,
In my driver that I have been converting to support OOB functionality with the EVL core, I have an interrupt handler that handles all interrupts from a device sitting on the PCIe bus. I was reading through the information on your wiki about interrupt pipelining in Dovetail. I was confused a bit on if there is work that I need to do in order to get interrupts & interrupt handlers to run out-of-band (and not be preempted by in-band linux processing), or if the EVL core takes care of that for me? If there is work I need to do with interrupt config & interrupt handlers in order to make them able to run out-of-band, where do I need to start?
Thanks!
Russell
