Touchpad files - doubt

[Joaotcs]

Hey! I have seen other works that, for touchpad (and touchscreen) they only use this kind of SSDT.aml, with no renames:

DefinitionBlock ("", "SSDT", 2, "hack", "_TPD0", 0x00000000) { External (SB.PCI0.I2C0.TPD0, DeviceObj) // (from opcode)

Scope (_SB.PCI0.I2C0.TPD0)
{
    If (_OSI ("Darwin"))
    {
        Name (OSYS, 0x07DC)
    }
}

}

Why is it better the XINI and XCRS rename than this?

This doesn’t work for me. You can try it. If this work it will be the best solution of course :).

It works for me... Try it (disable the rename XINI and CRS):

OMFG!! @Joaotcs its actually working! I spent months to find this kind of solution but without success! How you find it?

Would you like to create push request with these changes, or I can make it with your mention.

Thank you!

[Joaotcs]

It's OK for me, but as I have some modifications, I will fork it now, and upload my changes. Glad I could help ;) you sure did help me 😉

Thank you for sharing and constantly updating!

Now the how's.. Well, I have seen some works for other laptops that used this kind of aml files, but for different devices. I then modified and created new ssdt adapted to our laptops. In fact, I made first for the probook 440 g5, which uses another touchpad, and it worked. So I tried to make for this one. It also worked, so I created this topic because I didn't understand why the need for this renames :p

The code is getting pretty clean. I like it 😎👌
