Hi,

I am trying to make my touchpad work in GPIO interrupt mode and despite having the correct GPIO pin detected in IOReg, it still doesn't work (Pin 0x38, confirmed by setting it manually in the BIOS I unlocked). I have tried setting GPHD and TPDT to 0 and different values of TPDT (with the corresponding renaming TPDT,8 and TPDM,8 to XPDT,8 and XPDM,8 to avoid conflicts) and still not working in interrupt mode despite the pinning looking correct.

The specs of my laptop are :
Computer model Machenike Machcreator-A = Clevo NL4x_5xCU
Processor Intel Core i3-10110U
Memory 16 Gb DDR4 2667 MHz
Hard Disk Samsung 980 NVMe 1 Tb
Integrated Graphics Intel UHD Graphics 620
Monitor FHD 1920x1080 (15.6 inch)
Sound Card Realtek ALC293 (layout-id: 28)
Wireless Card Intel Wireless-AC 9462
Ethernet Card Realtek
Touchpad recognized on Windows, GNU/Linux and macOS as FTCS1000. ACPI Path seems to be _SB.PCI0.I2C0.TPD0 according to Windows device manager and DSDT.

I am currently using macOS Ventura 13.1 with OC 0.8.8 and already had the same problem on Monterey and Big Sur.

Could someone please help about this issue ? I have attached the DSDT.aml of my laptop (unpatched) and the EFI i am using currently. I hope there is enough information in this post.
Thanks

doubt you really need all these boot arguments:
-liludbgall liludump=60 -vsmcdbg smcdebug=0xff alctcsel=1 keepsyms=1 debug=0x100 -vi2c-force-polling npci=0x2000 igfxonln=1 -igfxblr darkwake=515 -hbfx-disable-patch-pci gfxrst=1 -hbfx-dump-nvram hbfx-ahbm=1025

and you are forcing polling mode?


the way I did mine (ELAN1000) was to add the Find and Replace:

also Lilu kext needs to be first in your list in your config.plist

Hi thanks for your answer,
I am using those boot args to help debugging the SMCBatteryManager issue, I will remove them when I'm done with the battery issue. I am forcing polling mode using the -vi2c-force-polling boot arg.

I can't find how to properly replace the corresponding strings in my DSDT, I tried to convert the Base64 to Text to find the corresponding code (to avoid replacing all _CRS and _STA to XCRS and XSTA) but obtained some unwanted characters in it like this :
"á
{DSYN�ñ�ñ
_CRS�ñäSBFBSBFI�"

Could you please help me find how to replace the corresponding _STA and _CRS ? I tried using BaseSkip and Count without any luck and ended renaming all _STA and _CRS methods to give it a try.

After that still can't see the _CRS and _STA methods from the modified SSDT-GPIO (attached to this post) on system DSDT (MaciASL). I don't know how to get this to work correctly.

I also tried adding the SSDT-I2CD.dsl (compiled to .aml) to obtain more debug without any subdevices showing in IOReg.

I honestly don't know what to do now...

well, you need to remove -vi2c-force-polling boot argument as that has nothing to do with your battery and will try and force polling mode....

you can use the echo command in terminal as per the example here:
https://www.tonymacx86.com/threads/guide-using-clover-to-hotpatch-acpi.200137/post-1308258

Code: 
u430:~ RehabMan$ echo -n GFX0|xxd
0000000: 4746 5830                                GFX0
u430:~ RehabMan$ echo -n IGPU|xxd
0000000: 4947 5055                                IGPU

I think there is a misunderstanding about the -vi2c-force-polling, I am using it only because the touchpad doesn't work in interrupt mode. It is for my everyday use to have a it "working in "safe mode"". I always remove it before testing interrupt mode ! I was talking about the other Lilu/VSMC-related boot args for the Battery.

Thanks for the guide, I managed to properly rename the corresponding _STA and _CRS.

However my Touchpad is still "detected but not working" in interrupt mode... Here is the IOReg in case you want to take a look at it :

will probably need to see your new zipped EFI as well

Here is my new EFI (cleaned some boot args, re-arranged the kext order, added SSDT and removed old renames-trials) :)

not sure that you need to have 2 SSDTs for your trackpad

do you have working battery on your hack? as this is required to be working fully before attempting to make your trackpad working

also test by enabling VoodooInput.kext from VoodooPS2Controller.kext

only boot argument you probably only need is igfxonln=1

also go back and check your kext ordering properly

Already tried with the exact same result

probably not much, but no need to throw in all kind of random boot arguments you can find, sometimes less is more when it comes to hackintoshing

also you could look into VoodooRMI

[Trackpad] VoodooRMI

VoodooRMI is a driver for modern SMBus and I2C trackpads from Synaptics. While many Synaptic trackpads work over PS/2, SMBus and I2C both have more bandwidth which allows the coordinates for all fingers to be sent in each packet. This aids multiple finger gestures and general responsiveness of...

I tested with my setup for I2C and it seems to work fine with no extra aml or Find and Replace entry in config.plist

EDIT:
not sure how you managed to get working battery status with only ACPIBatteryManager.kext with no extra aml file....?
