Subject: [QUERY]: Acknowledgment of edge triggered interrupts
Date: Sat, 30 Apr 2022 19:41:24 +0100 [thread overview]
Message-ID: <CA+V-a8va6YCtjswPVZvwBxZigpHfFpGOi5C2R7e5H49LpNWCYw@mail.gmail.com> (raw)
Hi Marc,
I am currently working on the irq-sifive-plic.c driver. The
irq-sifive-plic.c driver is currently implemented as a chained domain.
On our SoC which uses this block for EDGE interrupts we need to first
acknowledge the interrupt before handling it.
I came across a similar situation on a different driver (patch [0])
but it isn't a chained handler.
What approach should be taken for chained IRQ domains to handle such cases?

Cheers,
