YES. Remove any track pad kexts from S/L/E

Trying to build a static dsdt instead of acpi hotpatch.

All done , except for i2c gpio touchpad.

Can you help building it for me ?

Working great.

Can I ask fo something more ? If you have the time ..

Could you make a ssdt for i2c touchpad (for acpi hotpatch), based on origin dsdt ?

Thanks again for all your help.

Could you make a ssdt for i2c touchpad (for acpi hotpatch), based on origin dsdt ?

You can re-use your ssdt-I2xx.aml for that.

[mathewgx]

Yes, but I would like to compare it with yours , to see if I did it correctly.

Second reason is that with mine ssdt I still need to use sta and crs patch on clover.

With the dsdt you sent me these doesn't needed anymore.

[onemanosx]

Second reason is that with mine ssdt I still need to use sta and crs patch on clover.

For SSDT to function as an "override" to DSDT, it is required for return zero.

[mathewgx]

So , my ssdt for i2c is done right ?

SSDT-I2CX.aml.zip

[onemanosx]

[ref]mathewgx[/ref], This is the code for my ssdt. I dont need xcrs or xsta in clover.

Let's see if you can recreate yours

Trackpad is recognised , but iospecifiers still 0x33.

What am i doing wrong ?

Send me 5570.zip

[onemanosx]

iospecifiers still 0x33.

wont iospecifiers be tagged to your hardware?

[mathewgx]

Yes , but they are bigger than 47 so my touchpad doesn't work right.

[onemanosx]

Yes , but they are bigger than 47 so my touchpad doesn't work right

Then follow through the guide for iospecifiers larger than 0x2f

[mathewgx]

That's what I did.

Nevermind. Seems that I need _crs to xcrs patch at clover to get trackpad working right.

Added in 1 minute 35 seconds:

One more question.

Can you tell from my ioreg what type of touchpad i have ? It is synaptics?

[onemanosx]

Update: My trackpad now works with latest release!

My trackpad had a problem of not being able to use the latest kext release. And so I was stuck with release v2.0.2. Until recently, the dev replied to my GIT issue and mentioned to disable "Ignore built-in trackpad" in Sys Prefs > Accessiblity > Mouse & Trackpad

And true enough, I am able to use my trackpad using the latest release (v2.1.4 as of this writing). How awesome is this?

Anybody tried to use SYNA3602 touchpad? It is a touchpad that did not work even in Linux until kernel 4.19 and 5.0 and so it does not work in Android-x86 and ChromeOS either.

Why the PNG extension has been deactivated?

I think it is not, but I can try that guide anyway, right?

Btw, do you think it would be possible to update the images in this guide? Also the kext repo link no longer works. I think this would help a lot of people! Thank you very much.

You can try, of course.

Yeah, I'll reupload some of the missing images when I get the time soon! Thanks for the heads up.
