Subject: [patch 0/5, 2.6.9-rc3] generic irq subsystem, description
Date: Fri, 1 Oct 2004 22:45:33 +0200 [thread overview]
Message-ID: <20041001204533.GA18684@elte.hu> (raw)
this is a new release of the generic irq handling subsystem, against
2.6.9-rc3. This snapshot includes new ppc and ppc64 support written and
tested by Christoph Hellwig.
the core bits were reworked quite significantly. Changes:
- split up kernel/hardirq.c into individual files in kernel/irq/
- 80-90% of each converted architecture's irq.c file is now eliminated
by this patch. The most dramatic one is x64's irq.c - a mere 108
lines remained. The total effect on the 4 architectures covered so
far: more than 3000 lines of irq.c code removed while kernel/irq/*.c
remains around 1000 lines of code.
- more irq.h, interrupt.h, asm/hardirq.h and linux/hardirq.h
consolidation from Christoph and me.
- thorough cleanup of the generic irq code.
- compile-testing of the following architectures: x86, x64, ppc64, ppc,
ia64, s390, s390x. The first four were boot-tested as well.
there are 5 patches that will follow in the next 5 mails:
generic-hardirqs-core.patch
generic-hardirqs-x86.patch
generic-hardirqs-x64.patch
generic-hardirqs-ppc.patch
generic-hardirqs-ppc64.patch
note that it is still a goal of the patchset to not break the building
of any non-CONFIG_GENERIC_HARDIRQS platform - 3 such platforms were
compile-tested.
comments welcome,
Ingo
