[PATCH 0/1] Input/trackpoint: Add new ELAN trackpoint device variant id 7

[PATCH 0/1] Input/trackpoint: Add new ELAN trackpoint device variant id 7

[Yuan Yao]

The new ELAN trackpoint variant id 7 is found on thinkpad
X14 Gen1 laptop(Product Name: 21XMA006CD), it's now
incorrectly probed as Generic or Logitech PS/2 mouse but not
trackpoint.

Add ELAN variant id 7 to match the TP_READ_ID command return
value, probe the device as trackpoint correctly.

I tested the sensitivity/middle button lock/rate/resolution
setting, the trackpoint works well in daily usage and when
resume form system sleeping, no issue is found in my last
weeks usage.


BEFORE:
input: PS/2 Generic Mouse as /devices/platform/i8042/serio1/input/input63

AFTER:
psmouse serio1: trackpoint: Elan_variant7 TrackPoint firmware: 0xa1, buttons: 3/3
input: TPPS/2 Elan_variant7 TrackPoint as /devices/platform/i8042/serio1/input/input65

The patch is rebased to 7.4-rc1.

I wonder if we really need to say "Elan_variant7" or if we should simply
say "Elan" here as well.

Jingle, is this your part? What is the difference from Elan trackpoint
reporting 0x03 as its variant? 

Thanks.

Hi Dmitry/Yuan:

We have confirmed that FW A1 was never released by Elan. The Elan Variant ID has always been 3.

THANKS

Thanks for your reply.

I'm fine to just "Elan" if it's ok to you. I just want to
highlight the device has id 7 from other ELAN devices which
has 3, so I give it "Elan_variant7".

Thanks for your information, Let me share more details:

The trackpoint has driver from "ELAN
Microelectronics Corp." in windows 11 on same device.

In Linux I found the device is probed as generic mouse
device but not trackpoint device, it's hard to use due to
no sensitivity setting from sysfs. I found the reported id
0x7 is not in drivers/input/mouse/trackpoint.c's
trackpoint_start_protocol() after debugging, the trackpoint
is probed and works well after add the id 0x7 there.

So I thought this should be a ELAN device w/ ID 0x7 and
cooked this patch.

Hi Yao:

Could you help verify whether the color of the TrackPoint stick underneath the red cap can be used to identify the vendor?

White: ELAN
Other colors: Other vendors

Thanks

Hi Wu,

The thin stick under the red cap is black.

Also I visited the lenovo's supporting website, there's only
1 ELAN dirver for this thinkpad X14 gen1 model's trackpoint:

https://newthink.lenovo.com.cn/driveList.html?selname=ThinkPad%20X14%20Gen1

The laptop model I'm using is 21XM, the driver works well in
windows 11.

Now I'm confused on who is the real vendor of this
trackpoint device. I may ask help on Lenovo's supporting
website yet. Wu, is that ok to refer this mail there ?

RE: [PATCH 1/1] Input: trackpoint - Add new ELAN trackpoint device variant id 7

[Jingle Wu 吳金國]

Hi Yao:

Upon inquiry, it was confirmed that a black TrackPoint stick (0x07) underneath the red TrackPoint cap corresponds to a vendor that is compatible with the Windows ELAN driver.

THANKS
JINGLE

Hi Wu,

The thin stick under the red cap is black.

Also I visited the lenovo's supporting website, there's only
1 ELAN dirver for this thinkpad X14 gen1 model's trackpoint:

https://newthink.lenovo.com.cn/driveList.html?selname=ThinkPad%20X14%20Gen1

The laptop model I'm using is 21XM, the driver works well in windows 11.

Now I'm confused on who is the real vendor of this trackpoint device. I may ask help on Lenovo's supporting website yet. Wu, is that ok to refer this mail there ?

Are you at liberty to share the vendor name? Or should we mark it as
"Elan" or "Elan-compatible"?

Thanks.

Sorry to jump in; this is Vishnu from Lenovo.
I have now confirmed with the component owner and supplier that the
TrackPoint reporting variant ID `0x07` and firmware revision `0xA1`
are made by JYT/NDT, not ELAN. The physical check also identified the
corresponding button/stick as white. It uses the same ELAN driver for
Windows but has different FW.

Therefore, the patch should recognize `0x07` as the JYT/NDT variant
rather than naming it as an ELAN variant.

Can name it something like  [TP_VARIANT_JYT_NDT]          = "JYT_NDT"
or something like that.

Sorry, typo.
The physical check also identified the corresponding button/stick as
black/off-black

Ah thank you!
