Subject: [PATCH 00/39] irqdomain: Simplify interrupt handling
Date: Thu, 20 May 2021 17:37:12 +0100	[thread overview]
Message-ID: <20210520163751.27325-1-maz@kernel.org> (raw)

Although most device drivers only deal with an interrupt number, the
core IRQ code is mostly concerned with the irq_desc structure that
describes the full interrupt context (hierarchy, handlers, state).

However, the low-level interrupt handling code that relies on the
irqdomain abstraction has to perform an annoying dance to eventually
get the core code to invoke interrupt handlers: the irqdomain code
converts a low-level identifier to the unique Linux interrupt number,
and the core code resolves this into an irq_desc pointer.

Each of these two lookups ends-up parsing a radix tree (although the
irqdomain code can use a linear mapping for the smallest domains),
which is obviously one too many. Wouldn't it be nice if the irqdomain
would cache the irq_desc instead of forcing the core code to look it
up on each and every interrupt? This is what this long series is all
about.

There is roughly 3 parts here:

- a substantial amount of massaging for some architectures (nios, mips
  and powerpc) to disentangle weird include constructs (asm/irq.h
  including linux/irqdomain.h is pretty bad...) and simplify bits of
  the irqdomain code

- some rework of the irqdomain code to allow the caching of a irq_data
  pointer, unify the RCU behaviour and offer new APIs.

- Perform a bulk of conversions that turn constructs similar to
  generic_handle_irq(irq_find_mapping(domain, hwirq)) into a simpler
  call to generic_handle_domain_irq(domain, hwirq). Yes, this is a
  mouthful.

I've kept most of the conversions per-subsystem/per-arch in order to
keep the number of patches low (though it is debatable whether I have
succeeded).

This ends up with a negative diffstat, so it can't be completely bad!
Given the breadth of the changes, I do expect some breakage, although
I've extensively compile-tested it and the kbuild robot has been
invaluable in helping with the coverage.

Thanks,

	M.
