[PATCH] sh: fix proc file removal for superh store queue module

2006-08-06T15:57:48+00:00

Clean up proc file removal in sq module for superh arch.  currently on a
failed module load or on module unload a proc file is left registered which
can cause a random memory execution or oopses if read after unload.  This
patch cleans up that deregistration.

[PATCH] genirq: rename desc->handler to desc->chip

2006-06-29T17:26:21+00:00

This patch-queue improves the generic IRQ layer to be truly generic, by adding
various abstractions and features to it, without impacting existing
functionality.

While the queue can be best described as "fix and improve everything in the
generic IRQ layer that we could think of", and thus it consists of many
smaller features and lots of cleanups, the one feature that stands out most is
the new 'irq chip' abstraction.

The irq-chip abstraction is about describing and coding and IRQ controller
driver by mapping its raw hardware capabilities [and quirks, if needed] in a
straightforward way, without having to think about "IRQ flow"
(level/edge/etc.) type of details.

This stands in contrast with the current 'irq-type' model of genirq
architectures, which 'mixes' raw hardware capabilities with 'flow' details.
The patchset supports both types of irq controller designs at once, and
converts i386 and x86_64 to the new irq-chip design.

As a bonus side-effect of the irq-chip approach, chained interrupt controllers
(master/slave PIC constructs, etc.) are now supported by design as well.

The end result of this patchset intends to be simpler architecture-level code
and more consolidation between architectures.

We reused many bits of code and many concepts from Russell King's ARM IRQ
layer, the merging of which was one of the motivations for this patchset.

This patch:

rename desc->handler to desc->chip.

Originally i did not want to do this, because it's a big patch.  But having
both "desc->handler", "desc->handle_irq" and "action->handler" caused a
large degree of confusion and made the code appear alot less clean than it
truly is.

I have also attempted a dual approach as well by introducing a
desc->chip alias - but that just wasnt robust enough and broke
frequently.

So lets get over with this quickly.  The conversion was done automatically
via scripts and converts all the code in the kernel.

This renaming patch is the first one amongst the patches, so that the
remaining patches can stay flexible and can be merged and split up
without having some big monolithic patch act as a merge barrier.

[PATCH] Don't pass boot parameters to argv_init[]

2006-03-31T20:18:53+00:00

The boot cmdline is parsed in parse_early_param() and
parse_args(,unknown_bootoption).

And __setup() is used in obsolete_checksetup().

	start_kernel()
		-> parse_args()
			-> unknown_bootoption()
				-> obsolete_checksetup()

If __setup()'s callback (->setup_func()) returns 1 in
obsolete_checksetup(), obsolete_checksetup() thinks a parameter was
handled.

If ->setup_func() returns 0, obsolete_checksetup() tries other
->setup_func().  If all ->setup_func() that matched a parameter returns 0,
a parameter is seted to argv_init[].

Then, when runing /sbin/init or init=app, argv_init[] is passed to the app.
If the app doesn't ignore those arguments, it will warning and exit.

This patch fixes a wrong usage of it, however fixes obvious one only.

[PATCH] sh: convert voyagergx to platform device, drop sh-bus

2006-02-01T16:53:20+00:00

Trivial patch updating the voyagergx cchip code to reference a platform device
instead, now that the dma mask is taken care of.  Given this, there's no
longer any reason to drag around the SH-bus code, so kill that off entirely.

[PATCH] sh: drop maskpos from make_ipr_irq(), remove duplicate irq definitions

2006-02-01T16:53:20+00:00

Clean up some of the subtype IRQ definitions for IPR IRQ, and consolidate the
make_ipr_irq() definitions by dropping maskpos.  SH-4A was the only thing
interested in the maskpos, and this should be handled through INTC2 rather
than IPR.

[PATCH] sh: Make peripheral clock frequency setting mandatory

2006-02-01T16:53:19+00:00

Pretty much every subtype does this now anyways, and as we depend on it in a
few places being set to something sensible quite early on, it's better for a
new subtype to simply set a sensible default.
