[PATCH v2 00/13] Make mach/irqs.h optional

[PATCH v2 00/13] Make mach/irqs.h optional

[Rob Herring]

From: Rob Herring <rob.herring@calxeda.com>

This series removes the include of mach/irqs.h from asm/irq.h when
SPARSE_IRQ is selected. Platforms which select SPARSE_IRQ have been
updated.

This breaks platforms where SPARSE_IRQ is user selectable. This is on
purpose so that SPARSE_IRQ gets properly supported. We could push
HAVE_SPARSE_IRQ option down to the platforms that select it if that is
preferred. But as recent experience has shown, perhaps breaking platforms
is the only way to get some platforms updated.

Platforms either need to set nr_irqs in their machine desc or all irqchips
used by a platform need to allocate their irq_descs. There cannot be a
mixture. Once this is done, the platforms can select SPARSE_IRQ. shmobile
does the latter, and mnp and pxa do the former.

I've built all defconfigs, but don't have any of the affected platforms to
boot test. I really need shmobile testing with this series.

Changes from v1:
- Rework SH INTC_NR_IRQS and evt2irq/irq2evt macros
- Add commit "ARM: remove mc146818rtc.h from time.c"
- Add irqs.h removal for picocell
- Fixup newly added platforms in 3.3
- Drop sa1100 rtc changes. Not needed with platform device conversion.
- Make RTC_IRQ define to BUILD_BUG_ON
- Rebase to 3.3-rc1

This series is available here:

[PATCH v2 07/13] sh: intc: remove dependency on NR_IRQS

From: Rob Herring <rob.herring@calxeda.com>

SH intc has a compile time dependency on NR_IRQS. Make this dependency a
local define so that shmobile (and ARM in general) can have run-time
NR_IRQS setting.

[PATCH v2 08/13] ARM: mmp: remove NR_IRQS

[Rob Herring]

From: Rob Herring <rob.herring@calxeda.com>

Remove NR_IRQS and add a per machine .nr_irqs setting. Clean-up namespace
replacing usage of IRQ_BOARD_START with MMP_NR_IRQS.

[PATCH v2 10/13] ARM: shmobile: remove NR_IRQS

[Rob Herring]

From: Rob Herring <rob.herring@calxeda.com>

Remove NR_IRQS and explicitly include mach/irqs.h as needed. shmobile
properly allocates irq_descs for each irqchip, so setting .nr_irqs for
each machine is not needed.

[PATCH v2 11/13] ARM: only include mach/irqs.h for !SPARSE_IRQ

[Rob Herring]

From: Rob Herring <rob.herring@calxeda.com>

Make mach/irqs.h optional for SPARSE_IRQ. With this change irqs.h can be
removed by converting platforms over to sparse irq.

This intentionally breaks platforms that enable SPARSE_IRQ.

I don't get what you mean here.  The above seems contradictory.

You're right. The intro explains things more clearly. This breaks
platforms (at boot time) that don't select SPARSE_IRQ, but let users
enable it in their config. I don't understand why sparse irq is a user
visible config option. We could move HAVE_SPARSE_IRQ down to each
platform that selects SPARSE_IRQ and prevent enabling, but I think
allowing it to break is good encouragement for others to fix those
platforms. I'm open to other ideas.

The intro won't be part of the git history, so please make sure 
individual commit logs are sensible on their own.

SPARSE_IRQ shouldn't be a user configurable option.  There is just no 
point for a user configuring a kernel to be able to change this.

Updated the commit message to this (w/o the email word wrapping):

ARM: only include mach/irqs.h for !SPARSE_IRQ

Make mach/irqs.h optional for SPARSE_IRQ. With this change irqs.h can be
removed by converting platforms over to sparse irq.

This may break platforms where SPARSE_IRQ is user selectable and is enabled.
This is on purpose so that SPARSE_IRQ gets properly supported. SPARSE_IRQ
should not really be a user visible option.

Platforms either need to set nr_irqs in their machine desc or all irqchips
used by a platform need to allocate their irq_descs. There cannot be a
mixture. Once this is done, the platforms can select SPARSE_IRQ. shmobile
does the latter, and mmp and pxa do the former.

I agree, but I'm inclined to leave this alone for now. PPC doesn't ever
select SPARSE_IRQ, but enables it via many defconfigs. So I think
changing it may cause some problems.

Any other comments on this series? I guess all the maintainers copied
are happy with it as there have been no other comments. I like to get
this into next now and send pull request to Russell or arm-soc.

I think ppc can probably be moved to always enable SPARSE_IRQ since every
ppc machine goes through irq_domain anyway.

May be so, but only ~80 of ~100 ppc defconfigs enable SPARSE_IRQ. I'll
leave it to someone more familiar with ppc to change it.

I implemented Russell's suggestion:

config SPARSE_IRQ
	bool "Support sparse irq numbering" if MAY_HAVE_SPARSE_IRQ

and change all the existing 'HAVE_SPARSE_IRQ' to MAY_HAVE_SPARSE_IRQ
except those where SPARSE_IRQ gets selected.

In other words, on ARM get rid of HAVE_SPARSE_IRQ=y, don't select
MAY_HAVE_SPARSE_IRQ instead, but have each converted machine select
SPARSE_IRQ directly.  Then, people who want sparse irq to be a
question can have their cake.  While we can eat our cake too.

As a side-note, you may be pleased to know that I have SA11x0 stuff
converted to (and tested) with sparse IRQ.  That's with SA1111, the
UCB1x00 and Neponset expansion board for the Assabet all dynamically
allocating their IRQs.  The only fixed-numbered IRQs in SA11x0 in my
tree at the time of writing are the on-SoC IRQs, and the LoCoMo IRQs
(which I don't have the hardware to test for, so I'm not touching.)

Note that SA1111 support is fairly broken in current mainline because
of a half-completed (but still merged) patch which results in SA1111
overwriting IRQ0-55 with its own handlers.  Ouch.

This is /proc/interrupts for the Assabet+Neponset, with 49 SA11x0,
3 Neponset, 55 SA1111, and 16 UCB1300 IRQs:

That's really cool.

Not that there are many people who might still benefit from running that 
code, but like I said this should serve as a real and relatively simple 
example that might benefit more complex platforms.

Indeed, that's good going. I'm CCing a guy who might have a SA11xx board with 
LoCoMo chip (that's old zaurus sl55xx, right?).

I think I still do have old zaurus in some box somewhere (I stopped playing
with it once I got the newer one). And I think that Pavel Machek (CC) has one
too (I think that he wanted to give away to anybody who is wishing to maintain
the particular kernel parts and I think that in the end nobody took it).

Yep, I still have old collie (sl5500) machine. I don't really use
it...

Last night, I merged devel-stable into the stuff which gets built, and it
seems your IRQ changes are breaking PXA:

For SA1100, it's due to this change being done before my changes and
also possibly reverting of rtc driver changes. I'm working on fixes.

    ARM: sa11x0: convert to sparse IRQ

    Now that Neponset, UCB1x00 and SA1111 are all converted to use the IRQ
    allocation interfaces, we can enable sparse IRQ support for SA11x0
    platforms.
