touchpad support in kernel

[crystal relic]

hello, im trying to make a minimal kernel config on gentoo right now, everything is going well except touchpad support, the touchpad is a "GXTP5100:00" , grabbed this from dmesg and its a designware touchpad, i have looked at many guides, asked chat gpt (maybe a bit dumb when dealing with kernel issues but eh whatever) im reading a guide on touchpads since someone had a similar issue.

Hiya, tomorrow I can look at my old kernel config and see what I set. I believe there were things with "elantech" and another thing 🤔

[crystal relic]

That's what i thought too, i enabled everything referring to i2c, smbus, elan and designware, thank you!

[quartz tapir]

And still nothing?

[crystal relic]

Nope, didn't show up in dmesg

Nothing

So going through my kernel config file, I had these:

CONFIG_I2C_DESIGNWARE_CORE=y
CONFIG_I2C_DESIGNWARE_PLATFORM=y
CONFIG_I2C_DESIGNWARE_PCI=y

CONFIG_MOUSE_PS2_ELANTECH=y
CONFIG_MOUSE_PS2_ELANTECH_SMBUS=y
CONFIG_MOUSE_ELAN_I2C=y
CONFIG_MOUSE_ELAN_I2C_I2C=y
CONFIG_MOUSE_ELAN_I2C_SMBUS=y
CONFIG_HID_ELAN=y

There may be other things that were needed, so I'll keep looking, but try any of those first

HID_ELAN was not set, im recompiling rn

thank you in advance for helping out!

after enabling it it still doesnt work sadly, ill post my kernel .config, if you want/have time you can compare and check differences that make sense, i compared it with the dist kernel config and changed config options but sadly nothing changed

[quartz tapir]

These are things that are in my config that are different from yours (minus unset options)

Don't know if you get pinged from this if I don't ping you...

[crystal relic]

thanks, ill make the changes later when im done with maths homework, ill keep an eye on this channel, no need to ping me

and thank you very much for checking ofc

[crystal relic]

i checked and most of these options are not related to touchpad, 842 compress, mdio and numa for example, i proceeded to just enable everything in the acpi section
