[PATCH v2 0/6] hpet: fix build warnings and style

[PATCH v2 0/6] hpet: fix build warnings and style

[Corentin Labbe]

The original intent was to remove two build warnings, but finaly took
the opportunity to fix some style issues.
compile-tested for both x86/x86_64/ia64.

Changes since v1:
- add linux/io-64-nonatomic-lo-hi.h for writeq/readq as suggested by Clemens Ladisch

Corentin Labbe (6):
  hpet: remove unused variable hpet in hpet_ioctl_common
  hpet: remove unused writeq/readq function definitions
  hpet: fix checkpatch complains about spaces
  hpet: replace printk by their pr_xxx counterparts
  hpet: removing unused variable m in hpet_interrupt
  hpet: fix style issue about braces and alignment

[PATCH v2 2/6] hpet: remove unused writeq/readq function definitions

[Corentin Labbe]

On all arch using hpet, only i386 miss writeq/readq.
Instead of rewriting them, use linux/io-64-nonatomic-lo-hi.h which
already have them.

All?  There are others in this file no?
printk(KERN_CONT and printk(KERN_WARNING

And the conversion of

	printk(KERN_DEBUG
to
	pr_debug(

is not equivalent.  printk(KERN_DEBUG is always emitted.
pr_debug is only emitted with #define DEBUG or CONFIG_DYNAMIC_DEBUG
and a specific enabling of the line.

This patch might silence the warning, but it leaves the bug that
actually caused the warning.

As far as I can see, the computation of "base" should use "m".

But the entire algorithm is completely bogus because it does not
actually remove the race condition; the counter is likely to have
advanced beyond the "mc" value when the new comparator value is
written.  Also see arch/x86/kernel/hpet.c for how hpet_next_event()
handles this.

And why a non-periodic timer should generate periodic interrupts is
another question.

And nobody uses this crap.
So I'm really not sure what to do about this ...

Clemens

Perhaps this is clearer as:

I tried your patch on an HP Elitebook, but with rather limited
success. Before, I was able to use the touchpad in limited fashion
(https://bugs.freedesktop.org/show_bug.cgi?id=100345). With your patch
(applied on top of 4.10), the touchpad no longer reacts at all.

That said, I didn't find a patch 2/2 anywhere.. is there something
missing?

Thanks,
-Nikolaus

RE: [PATCH 1/2] Alps HID I2C T4 device support

[Masaki Ota]

Hi, Nikolaus,

Your Touchpad is 044E:120C, right?

PATCH 1/2 supports 044E:120C Touchpad device.
I think you can use all features of this Touchpad.

PATCH 2/2 supports 044E:1215 Touchpad device.
You don't need to care about this.

If Touchpad does not work completely, there is something an error.
What does dmesg show?

Best Regards,
Masaki Ota

Hi Masaki,

Yes, I think I have a 044E:120C. Is there a way to find out for sure?
It's not listed by e.g. lspci.

The touchpad is definitely not reacting to anything. evemu-record does
not show any events either.

I have attached the dmesg output.

Best,
-Nikolaus

Re: [PATCH 1/2] Alps HID I2C T4 device support

[Nikolaus Rath]

[-- Attachment #1: Type: text/plain, Size: 2192 bytes --]

Hi Masaki,

Yes, I think I have a 044E:120C. Is there a way to find out for sure?
It's not listed by e.g. lspci.

The touchpad is definitely not reacting to anything. evemu-record does
not show any events either.

I have attached the dmesg output.

Best,
-Nikolaus

RE: [PATCH 1/2] Alps HID I2C T4 device support

[Masaki Ota]

Hi, Nikolaus,

There is no 044E:120C device, but it looks like Alps Touchpad is detected as PS/2 Touchpad.

Actually, this Touchpad has two interfaces. One is I2C, the other is PS/2.
Default setting is I2C, and if the system does not support I2C, Touchpad works as PS/2.

However, both of interface should work properly on Linux.
I tested it on Ubuntu +4.10 kernel.

If you don't apply my patch, does device work as I2C? (044E:120C appears?)

Best Regards,
Masaki Ota

Hi Masaki,

Yes, I think I have a 044E:120C. Is there a way to find out for sure?
It's not listed by e.g. lspci.

The touchpad is definitely not reacting to anything. evemu-record does not show any events either.

I have attached the dmesg output.

Best,
-Nikolaus

Hi, Nikolaus,

Um, but demesg log does not have any error of this Touchpad.
It's a strange.

Re: [PATCH 1/2] Alps HID I2C T4 device support

[Nikolaus Rath]

Hi Masaki,

Well, I'd be pleasently surprised if every bug always came together with
an associated error message :-). No matter if there's a dmesg entry or
not, at the moment this patch will make life much worse for at least
some EliteBook owners.

Is there anything I can do to help you debug this?

Best,
-Nikolaus

RE: [PATCH 1/2] Alps HID I2C T4 device support

[Masaki Ota]

Hi, Nikolaus,

If you have a time, please try below debug method.

Download below file, copy it to your system and unpack.
https://www.filesanywhere.com/fs/v.aspx?v=8b716a8e5b6773baa799

Procedure ex:
#cd Desktop/LinuxModDebug
#sudo chmod 755 linux_kr_rebuild_tool_hid.sh
#sudo ./linux_kr_rebuild_tool_hid.sh /init linux-4.10.tar.gz
#sudo ./linux_kr_rebuild_tool_hid.sh /build DebugSrc

After that Touchpad all features should work.
If Touchpad does not work, something error appears on dmesg.

Best Regards,
Masaki Ota

Re: [PATCH 1/2] Alps HID I2C T4 device support

[Nikolaus Rath]

Hi Masaki,

Could you be a little more specific about what you need? I don't like
executing scripts containing several instances of 'sudo rm -rf
[something]'.

It seems that the script is meant to install debugging versions of some
modules. Could you simply send me a patch against the official kernel
that includes your debugging code? I'm perfectly able to compile it and
load the modules on my own :-).

Thanks,
-Nikolaus

Re: [PATCH 1/2] Alps HID I2C T4 device support

[Nikolaus Rath]

Hi Masaki,

Could you be a little more specific about what you need? I don't like
executing scripts containing several instances of 'sudo rm -rf
[something]'.

It seems that the script is meant to install debugging versions of some
modules. Could you simply send me a patch against the official kernel
that includes your debugging code? I'm perfectly able to compile it and
load the modules on my own :-).

Thanks,
-Nikolaus

RE: [PATCH 1/2] Alps HID I2C T4 device support

[Masaki Ota]

Hi, Nikolaus,

Could you add below debug message to hid-alps.c, and check it?
This device is "HID_DEVICE_ID_ALPS_T4_BTNLESS"(0x120C).
If the device is UNKNOWN, this device does not work completely.
And if the system does not call here, it has nothing to do with my patch.

static int alps_probe()
{ ...
...
...
printk("====> ALPS Debug Log: (%x) \n", hdev->product);
	switch (hdev->product) {
	case HID_DEVICE_ID_ALPS_T4_BTNLESS:
		data->dev_type = T4;
		break;
	case HID_DEVICE_ID_ALPS_U1_DUAL:
		data->dev_type = U1;
		break;
	default:
		data->dev_type = UNKNOWN;
	} 

Best Regards,
Masaki Ota

Re: [PATCH 1/2] Alps HID I2C T4 device support

[Nikolaus Rath]

Dear Masaki,

Thanks! I think I figured out the problem - it was on my side.

After I installed your patch, I ran "make localmodconfig". However, I
think prior to your patch my touchpad was handled by hid_generic - so
hid_alps was not loaded and the patched module thus never
build. However, your patch still prevented hid_generic from taking
control of the touchpad. After I explicitly enabled the hid_alps module,
my touchpad is now working again and, thanks to your patch, can now also
be configured.

Thanks again! Feel free to add a:

Tested-By: Nikolaus Rath <Nikolaus@rath.org

Best,
-Nikolaus

Re: [PATCH 1/2] Alps HID I2C T4 device support

[Nikolaus Rath]

Dear Masaki,

Thanks! I think I figured out the problem - it was on my side.

After I installed your patch, I ran "make localmodconfig". However, I
think prior to your patch my touchpad was handled by hid_generic - so
hid_alps was not loaded and the patched module thus never
build. However, your patch still prevented hid_generic from taking
control of the touchpad. After I explicitly enabled the hid_alps module,
my touchpad is now working again and, thanks to your patch, can now also
be configured.

Thanks again! Feel free to add a:

Tested-By: Nikolaus Rath <Nikolaus@rath.org

Best,
-Nikolaus

Hi,

I have this review in my inbox for a while, but couldn't find the time
to finish it earlier. Sorry about that.

I think the coding style guidelines requires to not use camelcase, so
it should be 'palm', not 'Palm'.

We don't rely on typedefs in the kernel (see
Documentation/process/coding-styles.rst). Please keep the "struct
t4_contact_data" naming (and lower case I think).

I'd rather have the name starting with a lower case (and everywhere in
the code).

No C++ comments, and why would you need to have those at first? Just
remove those.

You could have:

Maybe a switch/case on dev->type would be better here in case you need
to add further devices in the future.

Is this some new feature of U1 devices or am I reading it wrong?

This function is a massive rework of U1. I'd be more confident if you
split the patch in 2. One for the U1 rework to make it more generic, and
one other with just the T4 bits.

I am surprised checkpatch.pl doesn't complains about the spaces issues
around '+'.

Not in the current patch, but this would be better with
devm_input_allocate(), especially because this input device is leaked
and is never released in the current code.
