linux-next: mfd tree build failure

Hi Samuel,

Today's linux-next build (sparc allmodconfig) failed like this:

This has actually been happening since Aug 1.

Hi.

I'd have expected the other TMIO drivers to fail too.

get_irq_data is defined in linux/irq.h only if 

CONFIG_GENERIC_HARDIRQs is set and you arent on S390 (so why doesnt S390
fail?)

I dont see this as a big problem. As far as Im concerned, all the TMIO
drivers can depend on CONFIG_ARM.

It may not be a bad idea to add CONFIG_MFD_TMIO_SUBDEVICE so that TMIO
sub device drivers can only be selected when TMIO cores are selected.
This would neatly fix the earlier problem, rather than making al lthe
subdevices CONFIG_ARM.

The "Multifunction device drivers" menu depends on HAS_IOMEM.

It should be fixed by now.
All TMIO devices depend on ARM, and the MMC and NAND drivers now depend
on a new symbol (MFD_TMIO) selected when choosing one of the TMIO devices.

Samuel.

CCing in Haojian who did the driver.  I've not looked but I'd guess that
the issue is missing EXPORT_SYMBOL{,_GPL}s on the symbols above.

I'm sorry on inconvience. Now I attache the fix.

Samuel,
Could you help to review and merge this patch?

It's not caused by EXPORT_SYMBOL{,_GPL}. If I build in max8925 mfd
driver, issue is resolved.
Regulator subsystem could only be built in. And 8925 regulator driver
calls i2c operations that is defined in mfd driver. If 8925 regulator
is built it and mfd 8925 is built as module, it will cause linking
error.

Thanks
Haojian

Since regulator module is always built-in, MFD driver have to be built in.
If MFD driver is built as module, linking error will occur.

Actually, I fixed it. The problem was caused by the mfd and regulator drivers
having the same name, i.e. max8925.ko. I renamed the regulator driver to
max8925-regulator.ko, which also makes it more consistent with the rest of the
regulator drivers.

Stephen, the fix is already pushed, you can resume pulling the latest mfd
bits. Thanks for letting us know about the failure.

Cheers,
Samuel.

There's something more seriously wrong than the select with your config
here - the driver depends on (rather than selecting) I2C and you're also
seeing undefined references to the I2C API.  The select on MFD_CORE
should also be forcing that to be built in (it does normally).

Could you please post the actual configuration you're using?  I suspect
some Kbuild bug has been triggered here...

Sorry, I don't have the actual config (as I overwrite my build directory
between each merge).  However, if I checkout the mfd tree (alone -
nothing else in linux-next) and do "make ARCH=x86_64 allmodconfig", I get
the following in my .config:

CONFIG_I2C=m
CONFIG_MFD_CORE=m
CONFIG_MFD_WM831X=y

Oh, fail.  This is nothing to do with select, it's to do with bool.
Kbuild doesn't propagate the dependency from the boolean (which makes
sense for a lot of uses but not for this one).  The current "fix" used
by other drivers in the same situation is to depend on I2C=y which works
but means that we loose build coverage from allmodconfig.  I'll post a
patch for this shortly.

linux-next: mfd tree build failure

Hi Samuel,

Today's linux-next build (x86_64 allmodconfig) failed like this:

ERROR: "irq_to_desc" [drivers/mfd/wm831x.ko] undefined!
ERROR: "handle_edge_irq" [drivers/mfd/wm831x.ko] undefined!
ERROR: "set_irq_chip_and_handler" [drivers/mfd/wm831x.ko] undefined!
ERROR: "set_irq_noprobe" [drivers/mfd/wm831x.ko] undefined!

Probably caused by commit 8fc686c7369173519817f0cfbb2df9a3671d5b8d ("mfd:
Move WM831x to generic IRQ").  Maybe a Kconfig dependency is missing?

I have used the mfd tree from next-20091120 for today.

It actually looks as though set_irq_chip_and_handler (at least) is not
exported to modules.

True. Mark, I think we should get those symbols exported, unless you have a
better idea ? Having wm831x as a boolean choice from Kconfig doesnt sound too
god to me.

I don't see getting them exported flying, especially not in the
timeframe we've got for the merge window.  Keeping them non-exported has
been a deliberate decision on the part of the genirq maintainers.  I'll
send a patch making it built in.

Given the typical applications for these parts building the driver in
isn't the end of the world - there's a reasonable chance it'll be forced
built in for other reasons due to device-specific configuration.

Out of curiosity, what's the reasoning behind thatdecision ?

Thanks, patch applied.

Unless you're actually implementing an interrupt controller those APIs
should never be called and people should be using flags on request_irq()
or similar.  Driver authors have been awfully fond of bypassing those
APIs, but this prevents them doing so.

None of this is really a practical issue unless you implement an IRQ
controller in a driver and that's very rare (or has been up until now).

Could we split the above fix so that we get back to the:

	struct platform_device *rtc_pdev;
	struct platform_device *mbc_pdev;
	struct platform_device *adc_pdev;
	struct platform_device *input_pdev;
	struct platform_device *regulator_pdev[PCF50633_NUM_REGULATORS];

structure ? We can move to the index based structure after the next merge
window. That would make my life easier in terms of tree dependencies.
If you dont have time to do this change, I'll do it some time this week.

Thanks in advance.

Cheers,
Samuel.

Obviously caused by commit 9ec6cd8f2235ddeee5b39068956f14238a12a617
("mfd: Add 88PM8607 driver").

This build has CONFIG_I2C=m and CONFIG_MFD_CORE=m.

I have used the version of the mfd tree form next-20091005 for today.

I am sorry, but I don't have the exact .config file any more (I have
moved on in my creation of linux-next)  however, as I said, this was an
allmodconfig build on x86_64.  I also noted that CONFIG_I2C=m and
CONFIG_MFD_CORE=m, while the config entry that controls the building of
this driver is a bool so must have been 'y'.  So from a builtin driver,
you are referring to symbols that are only defined in modules.

Hi Stephen,

Thanks a lot for your help. I fix it now. Please help to review it. It's already passed the build test.

88PM8607 depends on I2C and MFD_CORE. Since 88PM8607 is built-in
kernel, it also requires that I2C and MFD_CORE are built-in
kernel also.

linux-next: mfd tree build failure

[Stephen Rothwell]

[-- Attachment #1: Type: text/plain, Size: 570 bytes --]

Hi Samuel,

Today's linux-next build (x86_64 allmodconfig) failed like this:

ERROR: "__set_irq_handler" [drivers/mfd/pcf50633-core.ko] undefined!
ERROR: "handle_level_irq" [drivers/mfd/pcf50633-core.ko] undefined!

Immediate cause is clearly commit
f52046b14b1e1a8a02ae48d0c69d39c5e204644f ("mfd: PCF50633 core driver")
which introduces this code.  The above functions don't appear to be
exported to modules.

I have dropped the mfd tree for today.

Applied to both my for-next and for-linus branches.
If Linus doesnt apply the patch, I'll resend a pull request tomorrow.

linux-next: mfd tree build failure

[Stephen Rothwell]

[-- Attachment #1: Type: text/plain, Size: 763 bytes --]

Hi Samuel,

Today's linux-next build (x86_64 allmodconfig) failed like this:

drivers/mtd/nand/tmio_nand.c: In function 'tmio_nand_write_buf':
drivers/mtd/nand/tmio_nand.c:251: error: implicit declaration of function 'writesw'
drivers/mtd/nand/tmio_nand.c: In function 'tmio_nand_read_buf':
drivers/mtd/nand/tmio_nand.c:258: error: implicit declaration of function 'readsw'

Most architectures don't implement readsw/writesw.

I reverted commit 4d6da2de1b09228989efb67a1f9e6d2ced075540 ("mfd: driver
for the TMIO NAND controller") until it has tighter controls in its
Kconfig patch. i.e. I have no idea what arches this should be built on.

Since there is no way to know wether an arch has readsw() and friends at
config time, I'd propose that bot the TMIO NAND and MMC drivers be built
only on ARM for now. If anyone every uses them on another platform, they
can add the support.

Should I redo the two drivers patchsets, or would you prefer a patch
fixing this after the fact?

No worries, I'll fix the Kconfigs later today.
