[PATCH 00/35] arm: omap: move intc to drivers/irqchip/

[PATCH 00/35] arm: omap: move intc to drivers/irqchip/

[Felipe Balbi]

Hi folks,

here's another rebase of the original series moving INTC
to drivers.

There aren't many changes, only some fixes here and there
because of recent changes to irq_domain and irqchip.

I have also added a patch to enable INTC address space
protection so that only privileged modes can access
INTC's address space.

Patches tested on top of v3.17-rc7 with a beagle bone black,
the only plataform I have which still uses INTC.

Tony, if you can run your PM test cases on your side, I'd
be really glad.

cheers

[PATCH 03/35] arm: omap: irq: start to remove irq_banks array

[Felipe Balbi]

We have a single bank in that array, this patch
is in preparation to remove that array. It just
shifts everything to a new set of functions
for register IO while also removing old ones.

[PATCH 07/35] arm: omap: irq: switch over to intc_readl on omap_intc_handle_irq

an almost blind conversion from readl_relaxed

While at that, also remove some hardcoded

if you respin the patchset you may want to call omap_intc_handle_irq
directly. It makes the review of the patchset less confusing.

(I was wondering why omap3 can call omap2_intc_handle_irq until I
noticed, that your previous changes made both functions simple
wrapper functions for omap_intc_handle_irq)

this is done later for a reason. At this point, omap_intc_handle_irq()
still misses proper annotations for asmlinkage and
__exception_irq_entry.

this is done later for a reason. At this point, omap_intc_handle_irq()
still misses proper annotations for asmlinkage and
__exception_irq_entry.

I guess that could be solved by moving the annotations to
omap_intc_handle_irq and just keeping omap{23}_intc_handle_irq as a
#define. Probably not worth the extra work, though.

[PATCH 14/35] arm: omap: irq: use IRQCHIP_DECLARE macro

[Felipe Balbi]

IRQCHIP_DECLARE macro is used to declare the same
of_device_id structure for irqchips, it's just
a helper. No functional changes.

Note that we're temporarily including irqchip.h
with its full path, until we move this driver
to drivers/irqchip/.

[PATCH 15/35] arm: omap: irq: drop .handle_irq and .init_irq fields

[Felipe Balbi]

now we can safely drop those fields from our machine_desc.

While at that, also drop the now unused omap_intc_of_init()
definition.

[PATCH 19/35] arm: omap: irq: drop ti,intc-size support

[Felipe Balbi]

we don't need that anymore since specific
devices are passing correct compatible flags.

keeping this code would avoid breaking the DT API. I suggest to
change it to something like the following:

if (!of_property_read_u32(...))
    dev_warn(dev, "ti,intc-size is deprecated, please update your DT file");

Apart from that the Documentation [0] should be updated (add
deprecation notice for ti,intc-size and add new compatible values)
and maybe moved to [1] (where other SoCs put their irq controller
binding docs).

[PATCH 20/35] arm: boot: dts: omap2/3/am33xx: drop ti,intc-size

we are now infering number of IRQ lines based

[PATCH 22/35] arm: omap: irq: call set_handle_irq() from .init_irq

[Felipe Balbi]

the idea is that board-files won't need to set
.handle_irq on their machine_descs, which lets
us drop a little more pointless code.

[PATCH 22/35] arm: omap: irq: call set_handle_irq() from .init_irq

[Felipe Balbi]

the idea is that board-files won't need to set
.handle_irq on their machine_descs, which lets
us drop a little more pointless code.

[PATCH 23/35] arm: omap: irq: drop omap3_intc_handle_irq()

[Felipe Balbi]

now that we're calling set_handle_irq() from
init_irq(), we can safely drop all callers to
omap3_intc_handle_irq() and its definition.

we don't need the ifdef if we have omap_nr_pending
telling us how many pending registers we have
on current platform. This solves a possible
problem where we could try to handle bogus
interrupts on OMAP2 and OMAP3 if using single
zImage kernel, because we would end up reading
the following pending FIQ register.

[PATCH 29/35] arm: omap: intc: switch over to linear irq domain

[Felipe Balbi]

now that we don't need to support legacy board-files,
we can completely switch over to a linear irq domain
and make use of irq_alloc_domain_generic_chips() to
allocate all generic irq chips for us.

This patch seems to somehow break off-idle for omap3 
where it no longer wakes up.

Other than that, this whole series boots fine for me.

Sure your bisection is correct ? This patch just switches from legacy
irq domain to linear irq domain.

Yes, I tried it a few times. Just enabling
retention idle hangs too with this patch.

Maybe it's omap3_prcm_irq_setup that relies on
11 + OMAP_INTC_START? There may be other such issues
remaining too but most should be already fixed up.

made me think why (if) OMAP4 works with that same setup. Does wake from
OFF work with OMAP4 ?

Not without similar changes, omap4+ has the same issue.. There's a RFC
series from Nishant to fix some of this, and Tero is moving the PRCM
into a driver.

OK yeah that's along the same lines with Nishant's RFC series in thread
"[RFC PATCH 0/7] ARM: OMAP4+: PRM: minor cleanups and dt support of
interrupts"

FYI, it did not compile, needs to include linux/of_irq.h. But yes,
it fixes the regression for me, Also now the whole series works for
me :)

Not without similar changes, omap4+ has the same issue.. There's a RFC
series from Nishant to fix some of this, and Tero is moving the PRCM
into a driver.

OK yeah that's along the same lines with Nishant's RFC series in thread
"[RFC PATCH 0/7] ARM: OMAP4+: PRM: minor cleanups and dt support of
interrupts"

FYI, it did not compile, needs to include linux/of_irq.h. But yes,
it fixes the regression for me, Also now the whole series works for
me :)

I might have sent the wrong version as I had that same build error and
fixed it localy.

good to know.

What do you want to do now ? Wait for PRCM to become a driver ? Wait for
Nishanth's series to get accepted ? I guess the same thing could be done
for OMAP3 and AM33, then we would have a chance of having working wake
from idle with the new irqchip.

I can repost the current series as it stands now once 17-rc1 comes out
(without the build failure ofcourse).. if that helps to move it out of
RFC status.

did you apply the quick little hack to prm3xxx.c ? prcm IRQ is hardcoded
to 11, once we switch to a linear irq domain, irq_base may change.

Yea, with that hack it works. However, you should make that into a 
proper patch and add it to this series, otherwise you will be causing 
regressions. Just renaming that tmp into something meaningful for now 
should be enough for me at least.

[PATCH 30/35] irqchip: add irq-omap-intc.h header

[Felipe Balbi]

OMAP INTC irqchip driver will be moved under
drivers/irqchip/ soon but we still have a dependency
with mach-omap2 when it comes to idle functions.

In order to make it easy to share those function
prototypes with OMAP PM code, we introduce this new
header.

[PATCH 30/35] irqchip: add irq-omap-intc.h header

[Felipe Balbi]

OMAP INTC irqchip driver will be moved under
drivers/irqchip/ soon but we still have a dependency
with mach-omap2 when it comes to idle functions.

In order to make it easy to share those function
prototypes with OMAP PM code, we introduce this new
header.

[PATCH 30/35] irqchip: add irq-omap-intc.h header

[Felipe Balbi]

OMAP INTC irqchip driver will be moved under
drivers/irqchip/ soon but we still have a dependency
with mach-omap2 when it comes to idle functions.

In order to make it easy to share those function
prototypes with OMAP PM code, we introduce this new
header.

I think these will all go away with DT based booting?
So it might be worth waiting for that rather than churn
all these files, or..

..how about we pass something like struct omap_intc_data
as pdata and let the intc driver populate function pointers
for these if runtime PM calls are not enough here?

That way we could have just minimal pdata header file.

you just asked me to rebase this series because now we had OMAP3 idle
working with DT. And now, you're asking me to hold on to this series
because not everything is DT-based yet.

This is the third time I rebase the series after a long hiatus and it
always comes out to the same result -> "let's wait some more".

I just don't like the idea of patching all these board files that
are going away anyways. If we need to do that, let's just add it
to common.h that's already included by all the remaining board-*.c
files. I know we should rather include the files directly, but in
this case that's just extra churn.

The real problem is how to properly deal with the save and
restore calls that idle code needs.

In any case, it seems we can merge quite a bit of this series
already and then deal with the problem parts.

Nope, it's always been "this series causes PM regressions"
and few other minor comments. And we have not been in any
position to really test that until with v3.16-rc4. And then
you always run out of time and nobody else does anything :)

I just don't like the idea of patching all these board files that
are going away anyways. If we need to do that, let's just add it
to common.h that's already included by all the remaining board-*.c
files. I know we should rather include the files directly, but in
this case that's just extra churn.

The real problem is how to properly deal with the save and
restore calls that idle code needs.

In any case, it seems we can merge quite a bit of this series
already and then deal with the problem parts.

when are they going away ? Are we really gonna delay this series until
those board-files eventually vanish ?

well, for system sleep we have callbacks from irq generic itself. The

sure, it at least some of those patches get merged, then it's less crap
for me to rebase every now and again.

you just said that we haven't been in any position to really test this,
so can it be that the status has always been "this series causes PM
regressions". We couldn't test that before, right ?

so can it be that the status has always been "this series causes PM
regressions". We couldn't test that before, right ?

sure, I have other stuff to do as well.

It's been working for legacy booting for years with the mainline
kernel, but not for device tree based booting until with v3.16-rc4.
I believe I tested your earlier series with my pending DT patches
though.

Right :) I and others can provide some help here, but it's
the mr. patch author that needs to follow up on this series

I ended up setting up another branch without this patch
at omap-for-v3.12/intc-v2. It now has dependency to the
SoC changes from Nishant and the const cleanup fix from Uwe.

This patch is not needed, let's leave this out, the functions
needed by the platform code won't need to be in a separate
header file as they are only needed by the platform code.

If you have a chance, can you please repost the remainging
patches to do the actual move to drivers, but without this
patch? And if we are lucky we'll get an ack from the
drivers/irqchip maintainers and I can apply those changes too
into omap-for-v3.12/intc-v2 ;)

so, if we don't add that header, we will have to include soc.h and
common.h with full (relative) path from drivers/irqchip/irq-omap-intc.c.
IOW:

#include "../../arch/arm/mach-omap2/common.h"

Neither soc.h nor common.h are part of the include path. I'd rather not
go down that route and just add this extra header. Even if you ask me to
move soc.h and common.h under <asm/mach/{soc,common}.h> we will already
have to modify every board file anyway.

so, if we don't add that header, we will have to include soc.h and
common.h with full (relative) path from drivers/irqchip/irq-omap-intc.c.
IOW:

#include "../../arch/arm/mach-omap2/common.h"

Neither soc.h nor common.h are part of the include path. I'd rather not
go down that route and just add this extra header. Even if you ask me to
move soc.h and common.h under <asm/mach/{soc,common}.h> we will already
have to modify every board file anyway.

[PATCH 34/35] irq: intc: remove unnecesary of_address_to_resource() call

[Felipe Balbi]

of_iomap(), which is called from omap_init_irq_of(),
already takes care of making sure we have a valid
resource to deal with. Because of that, we can
safely remove our explicit call to of_address_to_resource().

With Nishants changes for the omap3 PRCM interrupt and the
related .dts changes the PM works for me now with this series.

So I'm applying these into omap-for-v3.18/intc on top of
Nishant's changes in omap-for-v3.18/soc thanks.

With Nishants changes for the omap3 PRCM interrupt and the
related .dts changes the PM works for me now with this series.

So I'm applying these into omap-for-v3.18/intc on top of
Nishant's changes in omap-for-v3.18/soc thanks.

Great, thanks Jason for looking through them.

Felipe, can you please repost the missing patches with Jason's
changes and leaving out patch 30/35 to avoid board-*.c file
churn?

The branch to use for rebasing is omap-for-v3.18/intc-v2
that already contains the arch/arm/mach-omap2 related changes.

Tony
