[v2 0/4] Support for the TS-5500 platform

[v2 0/4] Support for the TS-5500 platform

[Vivien Didelot]

This is the second version of the set of patches which brings the support for
the Technologic Systems TS-5500 Single Board Computer.
This second version reads the BIOS during the initialization to ensure the
platform is a TS-5x00. The code is rebased on v3.1-rc3.

The first patch adds the base for the support of the board in
/arch/x86/platform/ts5500 and a documentation file in
Documentation/ABI/testing/sysfs-platform-ts5500.

The second patch adds support for GPIO.

The third patch adds support for the on-board LED.

The fourth patch brings support for the Analogic/Digital converter.

Jerome Oufella (1):
  platform: (TS-5500) add GPIO support

Jonas Fonseca (2):
  platform: (TS-5500) add LED support
  platform: (TS-5500) add ADC support

Vivien Didelot (1):
  platform: (TS-5500) add base support

New GPIO drivers should really go under drivers/gpiolib and be called
gpio-foo.c.

gpiolib should already be making sure there's only one user at once, no
need to bother open coding it in the driver.

Do you really need the lock to do a read?

Should they?  It seems a lot more reasonable to have them collected by
platform than by type of device (GPIO), *unless* they are shared.

There was some discussion of this, mostly for ARM, the general
conclusion being that sharing the code improves visibility of things for
the subsystem maintainer, ensures that the code gets reviewed (and
updated if things change) by subsystem experts and makes it more likely
that where there are things that can be shared someone will notice.

Grouping every driver for this platform was one of the main comments of
my first RFC set of patches. And indeed, the GPIO driver is really
specific to this platform, so it won't be shared.

That's the case for a lot of the ARM ones too, the same considerations
apply there.  There's generally a problem with people working needlessly
in isolation and a fairly low burden for subsystem maintainers.

What we've seen is that it's no fun for the arch/platform maintainer
when GPIO drivers start to proliferate the arch.

You should have Grants Likelys ACK on this no matter where it
ends up anyway so let's hear what he says?

Is there any chance for this function to be preempted before reading the
register, allowing a call to ts5500_gpio_direction_output to occur
before ts5500_gpio_get is completed?

Yes, but if that happens the mutex isn't going to help at all as you can
also be prempted before taking the mutex or after dropping it (or before
or after the function call itself...).

Wrapping an atomic operation in a mutex makes no sense no matter how you
slice it...

Thanks for the explanation. I removed the mutex lock here as there's no
critical section except for the inb() call in this function.

Same question as for the other patch, was this intended to be:

  Signed-off-by: Jerome Oufella <jerome.oufella@savoirfairelinux.com>

Ping? These patches cannot be advanced without a proper SOB sequence.

Also, with the attached config i get this build failure:

 arch/x86/built-in.o: In function `ts5500_adc_probe':
 ts5500_adc.c:(.devinit.text+0x1e1): undefined reference to `hwmon_device_register'
 make: *** [.tmp_vmlinux1] Error 1

Which kind of build failure is typically some sort of 
modular/built-in corner case combination:

 CONFIG_HWMON=m
 CONFIG_HWMON_VID=m
 # CONFIG_HWMON_DEBUG_CHIP is not set
 CONFIG_THERMAL_HWMON=y
 CONFIG_TS5500=y
 # CONFIG_TS5500_GPIO is not set
 CONFIG_TS5500_LED=y
 CONFIG_TS5500_ADC=y
 CONFIG_LEDS_GPIO=m
 CONFIG_LEDS_TRIGGER_GPIO=m

And is generally fixed by cleaner/better Kconfig dependencies.

Thanks,

	Ingo

Sorry for the late reply.

You're right, this should be:

Can you not do outb() from atomic context?  The reason lots of LED
drivers update the hardware in a workqueue is that they communicate with
the hardware over buses that can't be used in atomic context like I2C or
SPI but if that's not an issue then the workqueue is not required and
the code can be simplified.

outb() can definitely be executed from atomic context.

Good to know, thanks. I removed the work_struct and instead lock a mutex
before setting led->new_brightness and calling outb().

You can't take a mutex in atomic context...

OK, so what is the potential race that this mutex is called for?  If it
just means that the brightness can be redundantly set to the same value
more than once, no atomicity is needed.

I wrote the led_set function like:

  static void ts5500_led_set(struct led_classdev *led_cdev,
                             enum led_brightness value)
  {
          struct ts5500_led *led = container_of(led_cdev,
                                                struct ts5500_led,
                                                cdev);
          mutex_lock(&led->lock);
          led->new_brightness = (value == LED_OFF) ? LED_OFF : LED_FULL;
          outb(value, led->ioaddr);
          mutex_unlock(&led->lock);
  }

I guess the wrong value could be read if we get preempted just before
the outb() call, am I wrong?

And what happens if we do?

P.S. Your canonicalization of the value doesn't extend to outb().

In fact the new_brightness field wasn't necessary in this driver, so I
removed it and now the function only contains the outb() call. Thanks.

Yes, this should be signed off by Jonas Fonseca as well. This will be
updated in the next patches set.

I've already applied the current patches with the SOBs fixed (the 
merge window is getting close), to the tip:x86/platform branch.

Please send any fixes as add-on delta patches against tip:master:

   git://tesla.tglx.de/git/linux-2.6-tip.git

Thanks,

(tap, tap, is this thing on?)

Should i drop these commits:

 32a85aa727ce: x86/platform: Add TS-5500 ADC support
 3a338d79aa95: x86/platform: Add TS-5500 LED support
 2437b498abac: x86/platform: Add TS-5500 GPIO support
 37f9a16c166c: x86/platform: Add TS-5500 base support

from tip:x86/platform?

Had this (probably trivial) build failure been fixed when i reported 
it over a month ago then these commits could have been included in 
the v3.2 upstream kernel - now they will probably have to be delayed 
to v3.3.

Thanks,

	Ingo

Looking at these they all still have outstanding issues from code review
- from a quick glance they're all in the arch directory rather than the
relevant drivers directories and the GPIO driver is still replicating
functionality from the core in the driver (for detecting busy GPIOs).

Note that the patches are currently stalled, due to the build bug i 
reported. They won't be able to make it into the v3.2 upstream kernel 
if the bug is not fixed in time.

The patches are in the -tip tree:

  git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git

in the x86/platform branch (also integrated into the master branch).

Thanks,

Hi,

Sorry for the late reply, I wasn't able to work on this platform for
the last two months. Now I'm back :)

I will look at this build failure today.

Thanks for being patient,

Re: [v2 4/4] platform: (TS-5500) add ADC support

Would this fit into IIO?  It's still in staging and doesn't really
support system monitoring style ADCs (like those typically used for
thermal or supply voltage measurements) well so perhaps not.
