Just want to report that this works perfectly in ThinkPad L380

https://pasteboard.co/IAHs6Le.png

I have made a custom EFI for the HP EliteBook 840 G4. I managed to get the touchpad to work using VoodooRMI, but am struggling to fix the trackpoint. It does work if I use VoodooPS2Mouse, but it breaks the SMBus touchpad and in this repo's installation guide it's recommended to be disabled. VoodooRMI alone doesn't fix the trackpoint, as it's PS2 based and won't work with SMBus. How can I make the trackpoint work?

Use the implementation at https://github.com/kprinssu/VoodooI2CELAN/blob/master/VoodooI2CELAN/VoodooI2CELANTouchpadDriver.cpp to ignore input when typing

Using the patch for a few hours now and and finally the interoperability with Touchpad and Trackpoint seems perfekt.
However: Is there a way to adjust the latency of the typing detection? As I use key combanitions like CMD+TAB alot (also while using the mouse) but now the mouse gets stuck 1 second before it is usable again.

Thanks in advance!

Best, Phil

hi first of all. thank you for your hard work.
i want to know ELAN PS2 Support.
many elan ps2 touch pad user use ApplePS2SmartTouchPad.kext.
this driver is discontinued.
can you support elan ps2?

When dragging a file, when the finger reaches the edge of the touchpad, the original finger is pressed against the touchpad, and when the other finger presses the center of the touchpad to continue dragging, the dragged file is released.

Hi,
I don't know why but the cursor glitches like crazy and it seems to be a raw input issue. When I check it with several multitouch tools, they all show that the input cuts off for about 200ms in every 3-4 seconds. I tried to fix it with Karabiner's multitouch extension but no luck. You can repeat the problem by dragging a file, with 2 of your fingers on the trackpad, for more than 3-4 seconds.

had to modify the plist to get it working, but voodoops2 with smbus stops keyboard from working

using a different appleps2 kext without trackpad and mouse in it which fixed my keyboard issues completely

Thanks again

Hi @leo-labs !
I'm trying right now this kext on Catalina and works great!
All gestures are recognised correctly but I cannot enable/disable some features in SysPrefs:

I know that should be unrelated to your kext but in system preferences I cannot see any trackpad:

Maybe you can help me to figure it out.
Any suggestion on where to start is welcome!
Thanks,
Francesco

Hi Leo,
still absolutly happy with your patch ;-)
There are a few little things a mentioned over the time:

First: when I work without power cord my battery goes down to arround 5% and then I have a poweroff instead of the t480s going to sleep or power save. It seems the battery live is not counted correctly. I am NOT absolutly sure but I think this was introduced with your VoodooSMBus kext.
Have you seen something similar?

I'm trying to make the touchpad work better on Lenovo Thinkpad L390, that should have this SMBus.
I'm booting with open core. I followed this #20 (comment) post, and applied the patches.

1. It doesn't seem to work;
2. If I delete /Contents/Plugins/VoodooPS2Mouse.kext and its entry in OC config.plist keyboard and trackpad and trackpoint don't work
3. Where do I have to apply this in Opencore? https://github.com/VoodooSMBus/VoodooSMBus/blob/master/config.plist.patch
   Thanks in advance to everyone!

Just want to report that this works perfectly in ThinkPad T450S!

Hi,
i was trying to install the kext and the patch and I didn't able to make it work.
I investigate and I found this problem on the log of clover that in my opinion prevent the patch to work.
I have T480S running clover.
This is the boot log :

0:112 0:000 - [02]: com.apple.driver.AppleSMBusController (Prevent VoodooPS2Controller to attach to MOU) - invalid Find/Replace data - skipping!

And this is the line in the plist.config

I've an Asus TP412FA-EC452T, thats the only kext that worked for me yet!

But the clicks on the Trackpad are a bit confusing (normal click is 3 finger klick).
And Horizontal scroll is inverted.

I'm trying to fix it, but I don't understand the values for the "Custom MT2 Personality".

Is it possible to fix that by editing the info.plist?
Or do I have to modify the code?

It's possible to implement:

00:1f.4 SMBus [0c05]: Intel Corporation 100 Series/C230 Series Chipset Family SMBus [8086:a123] (rev 31) (subsys 103c:836b)

The touchpad is a ELAN and on linux and windows it says connected via SMBus.

The laptop is an HP Power 15 KabyLake.

I'm using VoodooSMBus and VoodooPS2Controller, the trackpad is smooth in most situation, but it can be suddenly unusable with no sign, and will restore to normal in a few minutes(sometimes a few hours), it's really annoying and I'm confused why this happens....

Sometime I lose my keyboard when in battery mode. I think it happens when I try to enable WIFI (e.g being in a train). I need to go to suspend - wait until the t480s sleeps - then I have to turn power on and - tada - the keyboard is back.
Any idea on this?

Firs of all, thanks for your amazing work!

I'm trying to install the kext on my Thinkpad X1 Carbon 6th gen which seems to have the same SMBus controller as T480s (pci8086,9d23).
However, after following all the instructions, the touchpad and trackpoint still seem to be driven by VoodooPS2Controller – e.g. no gestures, trackpad input doesn't get ignored while typing on keyboard, etc.
According to IORegistryExplorer, the kext seems to be loading and there's an item called VoodooSMBusControllerDriver attached to SBUS. The trackpad menu in System Prefernces indicates full gesture support but none of them work.

I took a look at the MOU node in IORegistryExplorer and it seems like the VoodooPS2Controller is still attached to it. PNP0F13 in MouseNameMatch seems to still be present despite the patch. I've tried removing it from VoodooPS2Controller.kext/Contents/Info.plist manually, however after that all the input devices (keyboard, trackpad, nub) would stop working altogether.

If I just remove VoodooPS2Touchpad.kext plugin, the trackpad and the trackpoint stop functioning too.

Hi,
first I want to thank you for your effort. I was able to make my Thinkpad t480s works.
I just have one small issue, i cannot have temperature reading on the sensors on my computer.
And I looked online and I tried to find the fake SMC directory on the source code and I didn't find it.
Please, can you advise me on what should I do?
Thank you. Very much

Hello, I'm a user with a Lenovo X1 Extreme Gen 3 (20TK001JUS) running OpenCore 0.6.9 with Catalina 10.15.7 and I was having some issues with the trackpoint not functioning on some restarts, as well as the fact that the clickpad always functioned as a left-click despite whatever the System Preferences' "Secondary Click" setting was set to.
After looking into it, it turns out that while the kexts were successfuly injected according to the OC logs, they were not loading properly according to kextstat and IOReg. I went into the section on SMBus troubleshooting and as it turns out, adding my SMBus' controller's Vendor and Device ID's to the VoodooSMBus.kext's info.plist as the troubleshooting guide recommended worked perfectly to get the kexts appearing. It didn't solve either issue, but that's besides the point.

Since the troubleshooting guide reccomends "If your device is compatible and adding the device-id worked, please submit a Pull Request or issue!" here I am doing exactly that.

My SMBus' controller's Vendor ID was 8086, and the Device ID was 06A3.

Either we report these events via the transducers or better we add another IOHIPointing device as client to ELANTouchpadDriver

Hi，i have a laptop which model is HP 340 G4 with a PS2 Elan touchpad , it also has Intel I/O Controller Hub Sunrise Point-LP (PCH) ,and id is pci8086, 9d23.

When i put the VoodooSMBus.kext into the BootLoader like OC or clover, i can see the kext is correctly be loaded through IORegistryExplorer

So i try to follow the Installation steps and reboot , touchpad Preferences shows correct,but the touchpad has not response. Move the point , click, scroll, swipe etc... all gestures is not work.
It seems that the driver did not detect the input signal at all.

Can you solve this problem?
i can provide any debugging informations if you need for your great job

Thanks!

work well on Thinkpad T470P
deviceId: 0xa1238086

Hi,
I'm using this kext since day 1 and it works flawlessly.
but even since there's a little problem I can't figure it out:

sometimes the trackpad slow down and the cursor is more like "smooth and delayed" than "precise".
This lasts few seconds ~30 and then everything goes back to normal.

This happened in Catalina + clover and in current Big Sur + OC.

Any idea on what might be going on?
Tried to disable several kext without success.

Also, seems happening more when plugging the thinkpad to charge it.

ps. using a Thinkpad T480s

maybe @leo-labs can help there

Add VoodooSMBus (or even just SMBus) to log statements. Additionally, dmesg doesn't add new lines to every logging statement, so all logs should have a new line at the end.

I read the OC configuration.pdf and couldn’t find out how I would apply alle the InfoPlistpatches provided in the repo. I assume you would apply it with Kernel/Patch but that won’t work. Some guidance would be appreciated.

Now, I am working on OC bootloader, as I added the patch in the config.plist, the original patch didn't work. Any suggestions on it?

Remove touchpad/trackpoint related information and clarify driver model

Hi Leo,
thanx for your work! Really like your approach.
I tried to install your kext this morning but unfortunatelly, the touchpad is not working after reboot.

• I added your patch to the END of KernelToPatch section in my config.list (The same section the other for patches from linusyang92 are - I'm using his EFI).
• Removed VoodooPS2Mouse
• Afterwards I copied your kext to /L/E and cleared the kextcache (sudo kextcache -i /)
• Rebooted
  but now my touchpad is not working any more.

Questions:

• is /L/E the correct location or is it better to copy your kext to EFI folder?
• gokula provides an SSDT-SMBUS.dsl, do we need something like this?
• what about AppleIntelLpssiI2C.kext and AppleIntelLpssiI2CController.kext, do they need to be manually deleted from system or can they stay in place?

Kind regards
Kai

As long as the next installed following by your installation instructions, the trackpoint, trackpad and keyboard all not working

(ThinkPad P52, PCH SMBUS 8086-A323)

This should be a rather simple change if someone else wants to pick this up. If no one does it by the time I finish the Synaptics stuff, I'll do it, but that'll be a while.

VoodooSMBusController currently calls handleHostNotify in it's slave devices, though likely a better alternative is using IOService's internal messageClient and message method. This would remove the need for VoodooSMBusSlaveDevice, reducing a class needed as well. You would need to make your own MessageType likely, though it's just a uint32 that doesn't interfere with anything else.
Edit: handleHostNotify has no arguments, so we shouldn't need to pass any through message either, simplifying it.

Hello there,

I have a Lenovo V130-15IKB which apparently uses Synaptics SYNA2B42, I tried VoodooI2C to find out after two sleepless nights that my Synaptics is directly connected to the SMBus controller which made me come to this project. Trying with VoodooI2C there were no change at all even in Trackpad PrefPane, but once I used your amazing kext, there was a tiny change that the Trackpad PrefPane was finally enabled but to find out later that your kext doesn't support Synaptics yet as I understood.

So is there any hope for us? this is literally my last step for a usable hackintosh on a Laptop.
