Subject: [PATCH v2 01/12] ARM: riscpc: use GENERIC_IRQ_MULTI_HANDLER
Date: Tue, 30 Nov 2021 13:58:50 +0100 [thread overview]
Message-ID: <20211130125901.3054-2-ardb@kernel.org> (raw)
In-Reply-To: <20211130125901.3054-1-ardb@kernel.org>
From: Arnd Bergmann <arnd@arndb.de>
This is one of the last platforms using the old entry path.
While this code path is spread over a few files, it is fairly
straightforward to convert it into an equivalent C version,
leaving the existing algorithm and all the priority handling
the same.
Unlike most irqchip drivers, this means reading the status
register(s) in a loop and always handling the highest-priority
irq first.
The IOMD_IRQREQC and IOMD_IRQREQD registers are not actaully
used here, but I left the code in place for the time being,
to keep the conversion as direct as possible. It could be
removed in a cleanup on top.
