VoodooI2C Help and Support

[ben9923]

Hello,
My ELAN1300 works like a charm without dsdt patch but stop working when I left it for about 5 minutes without touching. restart the computer makes it work again. Voodooi2c.kext & voodooi2chid.kext installed. please help

You're running in polling mode, that's not recommended. Are you on CFL/CNL/etc?
Please attach an archive made with gen_debug.sh, make sure IOReg is included.
Please attach 2 archives - one when it still works, and another after it stops working.

Hello. How to fix this polling mode ? I followed the GPIO pinning guide. I don't know what is CFL CNL sorry
The touchscreen ID is TPL0 and Touchpad is ETPD
thank you

From your kernel log:

2019-04-19 16:26:11.208258+0700 0x120      Default     0x0                  0      0    kernel: (kernel) VoodooI2CControllerDriver::VoodooI2CDeviceNub Warning: Could not find any APIC nor GPIO interrupts; if your chosen satellite implements polling then VoodooI2CDeviceNub will run in polling mode.

CFL = Coffee Lake, CNL = Cannon Lake. Those generations are not supported by VoodooGPIO, but yours is, so you should be able to use GPIO interrupts. Your patching is not successful tho.

You obviously did not follow the GPIO pinning guide. You've followed the polling guide. You removed the APIC interrupt from _CRS, but did not add SBFG with the GPIO pin.

Documentation

If further help is necessary, please make sure IOReg is attached for both cases (.ioreg file), not generic_ioreg.txt.
The .ioreg file shouldn't be 30MB...

Hi, after updated to VoodooPS2Controller to 2.0.1.1 (from https://github.com/acidanthera/VoodooPS2) can no more boot macOS (whereas everything is OK when I downgrade to the 1.9.2 version from Rehabman)
Before further investigations would like to know Is there is a known incompatibility or recommendations for this branch when using VoodooI2C ?

Thanks. I added SBFB line and it works

Same class names are used for the native engine on VoodooPS2 (as the classes were just copied from it...). See the latest commit, try compiling it yourself.
The VoodooI2C repo should really be a submodule of the VoodooPS2 repository. The code shouldn't be copied that way...

Big Thank You @ben9923 @alex.daoud

I just tried VoodooI2C + VoodooI2CElan v2.1.6 - Asus Zenbook Skylake - ELAN1000

- Trackpad Right-Click works again. Terrific! I had the Zenbook scaling issue causing Right-Click not to work. Now, it's fixed in 2.1.6.

- 1-Finger, 2-Finger, and 3-Finger gestures still all work

- I can Left-Click the top of a window, keep Left-Click pressed, and use another finger across the trackpad to drag the window around. Before, this Left-Click drag wasn't working.

Excellent work! Essentially everything works in 2.1.6: Left-Click, Right-Click, gestures, Left-Click drag.

@ben9923 is there any new kextpatch to disable Apple I2C drivers from loading, I never had trouble with that but I just clean installed 10.14.4 and haven't changed any patch at all, but when I check IOREG:

There's no new patch. The existing ones should really last forever, they search for 'IOKit' in the Info.plist, and it's pretty much a must to allow them matching

For some reason, can't tell why, Apple's kexts will eventually load, but that's only if VoodooI2C did not. Make sure it's installed correctly, as VoodooI2C + the 2 patches should work well

You can attach problem reporting files if you can't figure that out, I guess

I will attach new files in a few minutes, will just try old kext (2.1.4 with fixed scaling) that someone uploaded, it was working fine on my ELAN0618, I can see on kextcache that only VoodooI2C is loaded and not VoodooI2CELAN.kext.
Will do some more testing, if I can't solve it, I will upload files as it will be out of my knowledge.
