[PATCH v3] Input/i8042: Merge quirk tables and add Clevo devices

[PATCH v3] Input/i8042: Merge quirk tables and add Clevo devices

[Werner Sembach]

Following a suggestion by Hans de Goede, I reworked the quirk tables in the
i8042 driver. Now all quirks only use a single table. This makes quirks
easier to search by device and reduces code line count and memory usage.

The 2nd patch adds new debug output to make it easy to see if a specific
quirk got applied or not.

The third patch adds a list of Clevo devices that need multiple quirks.
With the reworked table they don't need to be inserted multiple times now,
which was required in v1 and v2 of this patch.

I also included the extra quirk for the Clevo NS7xMU, which was a separate
patch before.

[PATCH v3 1/3] Input/i8042: Merge quirk tables

[Werner Sembach]

Merge i8042 quirk tables to reduce code duplication for devices that need
more than one quirk.

Also align quirkable options with command line parameters and make vendor
wide quirks per device overwriteable on a per device basis.

Some duplication on the ASUS devices is required to mirror the exact
behaviour of the previous code.

Can you explain this a bit more ?

have you checked that i8042_platform_init() *always*
gets called before i8042_pnp_init()?

Maybe just add something like this:

#ifdef CONFIG_X86
static void __init i8042_check_quirks(void)
{
	const struct dmi_system_id *device_quirk_info;
	uintptr_t quirks;

	device_quirk_info = dmi_first_match(i8042_dmi_quirk_table);
	if (!device_quirk_info)
		return;

	quirks = (uintptr_t)device_quirk_info->driver_data;

	if (i8042_reset == I8042_RESET_DEFAULT) {
		if (quirks & SERIO_QUIRK_RESET)
			i8042_reset = I8042_RESET_ALWAYS;
		if (quirks & SERIO_QUIRK_NOSELFTEST)
			i8042_reset = I8042_RESET_NEVER;
	}

	/* Do more quirk checks */
}
#else
static inline void i8042_check_quirks(void) {}
#endif

(above the declaration of i8042_pnp_init())

And call i8042_check_quirks() in both
i8042_platform_init() and i8042_platform_init() ?

This also abstracts some of the CONFIG_X86
ifdef-ery out of the other functions.

I'm not a fan of these 2 helper variables, you can do this directly,
see above.

> +	const struct dmi_system_id *device_quirk_info;

All 3 these variables will trigger unused variable
settings when compiling without CONFIG_X86 set. Note
introducing the i8042_check_quirks() helper as I suggest
above avoids this without needing more #ifdef-ery.

As far as i can tell i8042_pnp_init() is only ever called inside i8042_platform_init() so moving this check from pnp
init to platform init should be no problem.

Fixed by moving it to its own function as you suggested.

My original reasoning for the helper variables was that i didn't want to move the i8042_reset evaluation, but then did
it anyways in the next patch after checking that pnp_init doesn't use the variable.

[PATCH v3 2/3] input/i8042: Add debug output for quirks

[Werner Sembach]

Make new quirk table easily debugable with some debug output.

With no functional change, evaluation of i8042_reset_quirk and
i8042_reset_never_quirk had to be moved for this.

[PATCH v3 3/3] input/i8042: Add TUXEDO/Clevo devices to i8042 quirk tables

[Werner Sembach]

A lot of modern Clevo barebones have touchpad and/or keyboard issues after
suspend fixable with nomux + reset + noloop + nopnp. Luckily, none of them
have an external PS/2 port so this can safely be set for all of them.

I'm not entirely sure if every device listed really needs all four quirks,
but after testing and production use. No negative effects could be
observed when setting all four.

The list is quite massive as neither the TUXEDO nor the Clevo dmi strings
have been very consistent historically. I tried to keep the list as short
as possible without risking on missing an affected device.

This is revision 3. The Clevo N150CU barebone is still removed as it might
have problems with the fix and needs further investigations. The
SchenkerTechnologiesGmbH System-/Board-Vendor string variations are
added. This is now based in the quirk table refactor. This now also
includes the additional noaux flag for the NS7xMU.
