[PATCH 00/15] Add various missing GENERIC_HARDIRQS dependencies

[Heiko Carstens]

Hi all,

this patch set just adds various missing GENERIC_HARDIRQS to a couple of
Kconfig files in order to make an s390 allmodconfig/alldefconfig compile
again.
This is necessary since during the last merge window s390 got CONFIG_PCI
and with that also CONFIG_HAS_DMA and CONFIG_HAS_IOMEM. These new config
options enable lots and lots of new drivers for s390, which however does
not support GENERIC_HARDIRQS.
Therefore a couple of drivers do not compile. To fix this, just add the
missing dependency (instead of sprinkling a !S390 dependency across the
whole tree).

The patches below are all against linux-next as of today.

If the you as the maintainers would take the patches that would be great.
Or please let me know if any patch should go in via the s390 tree.

Thanks!

[PATCH 01/15] drivers/input: add couple of missing GENERIC_HARDIRQS dependencies

[Heiko Carstens]

When removing the !S390 dependency from drivers/input/Kconfig a couple
of drivers don't compile because they have a dependency on GENERIC_HARDIRQS.
So add the missing dependencies.
Fixes e.g. this one:

drivers/input/keyboard/lm8323.c: In function ‘lm8323_suspend’:
drivers/input/keyboard/lm8323.c:801:2: error: implicit declaration of function ‘irq_set_irq_wake’
	[-Werror=implicit-function-declaration]

[PATCH 02/15] drivers/i2c: remove !S390 dependency, add missing GENERIC_HARDIRQS dependencies

[Heiko Carstens]

Remove !S390 dependency from i2c Kconfig, since s390 now supports PCI, HAS_IOMEM
and HAS_DMA, however we need to add a couple of GENERIC_HARDIRQS dependecies to
fix compile and link errors like these:

[PATCH 03/15] drivers/mfd: add missing GENERIC_HARDIRQS dependecies

[Heiko Carstens]

A lot of mfd drivers select MFD_CORE which however depends on
GENERIC_HARDIRQS support.
So add the missing dependency to all drivers to get rid of
this link error:

[Heiko Carstens]

The SuperH VEU mem2mem video processing driver (VIDEO_SH_VEU)
calls devm_request_threaded_irq() and therefore should depend

Texas Instruments WL1273 I2C FM Radio (RADIO_WL1273) selects
MFD_CORE, which itself depends on GENERIC_HARDIRQS.
So add the dependency to the TI driver as well.

Shouldn't this be fixed rather in asm-generic/io.h?
Something like,

#if defined(CONFIG_HAS_IOPORT) && defined(CONFIG_GENERIC_IOMAP)
extern void __iomem *ioport_map(unsigned long port, unsigned int nr);
extern void ioport_unmap(void __iomem *p);
#else
static inline void __iomem *ioport_map(unsigned long port, unsigned int nr)
{
	return (void __iomem *) port;
}

static inline void ioport_unmap(void __iomem *p)
{
}
#endif /* CONFIG_HAS_IOPORT */

Ditto, how about defining

#ifndef CONFIG_GENERIC_HARDIRQS
#define irq_get_irq_data(x)  NULL
#endif

somewhere appropriately?

No, it is intentional that the CONFIG_HAS_IOPORT symbol refers to
the fact that you can use the ioport_map function, in order to
disallow building drivers that depend on this function when it
is unavailable. I actually want to change this, but in the opposite
way of what you are proposing:

I think CONFIG_HAS_IOPORT should refer to the fact that the
inb/outb family of functions are usuable and be unset when
they are not provided, and I would introduce a new
CONFIG_HAS_IOPORT_MAP symbol for those (few) platforms that
have a working inb/outb but no ioport_map.

Why not just make CONFIG_GENERIC_HARDIRQS mandatory for all
platforms. It is use almost everywhere now.

Yet another Kconfig, but sounds reasonable :)

Right... I just wanted to make s390 compile with the Kconfig methods we use
since nearly a decade and not change the world ;)

I haven't looked into it, but I doubt if that is possible without large
effort, if at all. s390 doesn't have any irq chips, nor something like
edge or level triggered irqs.
Instead we have floating interrupts. Does that fit into the concept of
GENERIC_HARDIRQS at all?
If so, we can give it a try, sure. But that won't happen any time soon.

Or are you simply proposing we should have both, our own irq handling plus
GENERIC_HARDIRQS with dummy functions?

Your patch looks fine here, I was just mentioning that this is going to
change. After my patch, things will be different for s390 as well, because
it presumably won't provide the inb/outb accessors any more then
and not set the (new) CONFIG_HAS_IOPORT.

I think you should use GENERIC_HARDIRQ just for PCI, and rename the s390
interrupt handling to something that does not conflict. I understand
that the concepts are quite different, but with PCI support, you actually
do get all the weird interrupt hardware.
More importantly, some features provided by GENERIC_HARDIRQ are replacing
the traditional interfaces now, e.g. devm_request_irq() is actually
recommended over request_irq() for normal drivers these days, as it
simplifies the error handling.

That sounds reasonable. And a quick grep seems to indicate that s390
is the last architecture with !GENERIC_HARDIRQS.
However having two completely different IRQ subsystems within one
architecture will bring up some interesting questions like e.g.
how should /proc/interrupts look like? Or /proc/stat:intr ?

Jan considered turning GENERIC_HARDIRQS on for PCI support, but didn't.
I don't know why he didn't and since he left, we can't ask him anymore.

So for the time being I'd appreciate it if we can simply add the
additional GENERIC_HARDIRQS dependencies where needed, since I consider
a working allmodconfig quite important.
Later on we should indeed try to switch to GENERIC_HARDIRQS and then
git rid of that config option completely. However I leave that to
Sebastian and Gerald who now take care of our PCI code ;)

Thanks,
Heiko

/proc/interrupts can still be managed by architecture code, and
you can put in there whatever makes sense. I would suggest
keeping the current code for it, or adding the GENERIC_HARDIRQ
support at the end of it.

I briefly talked about it with him a couple of months ago, and
he said that the thought Martin would hate it.  I still think
it's the best solution though.

OK, then I'll queue the sound patch to sound.git tree as is.

I would be very careful with this statement. While devm_request_irq()
does simplify error handling in several cases I have also seen countless
examples when it was used with non devm_*-managed structures that are
freed by hand opening race window where interrupts can be delivered and
use structure that is already freed.

Thanks.

[PATCH 15/15] drivers/serial: add GENERIC_HARDIRQS dependency

Since SERIAL_CORE needs GENERIC_HARDIRQS (see below) and most serial drivers
select it, just add a GENERIC_HARDIRQS dependency to all serial drivers.

Fixes the compile error below:
