How to fix I2C Trackpad?

after tried many times, trackpad still not working

Here is my devices:

I followed voodooi2c guide carefully:

correct my ACPI ID is TPD1, and know my CPU is Broadwell no need GPI0 controller patch, and I2C Controller Patches?
Windows Emulation patch will done with SSDT-XOSI.aml
Look at IOInterruptSpecifiers to know the hexadecimal APIC pin number is 0x1e mean 30 in decimal, less than 47, then can proceed to install kexts.

But at Step Ensure I2C Serial bus name is correctly labelled, I not sure about it. Here is original method from DSDT:

                    Interrupt (ResourceConsumer, Level, ActiveLow, Exclusive, ,, _Y2A)
                    {
                        0x0000001E,
                    }
                })
                If (LEqual (GR13, One))
                {
                    CreateDwordField (SBFI, \_SB.PCI0.I2C1.TPD1._CRS._Y2A._INT, VAL3)  // _INT: Interrupts
                    Store (0x1B, VAL3)
                }

                If (LOr (LOr (LEqual (BID, 0x80), LEqual (BID, 0x82)), LEqual (BID, 0x83)))
                {
                    CreateDwordField (SBFI, \_SB.PCI0.I2C1.TPD1._CRS._Y2A._INT, VAL4)  // _INT: Interrupts
                    Store (0x1A, VAL4)
                }

                Return (SBFI)
            }
        }

I renamed SBFI to SBFB and remove:

                    Interrupt (ResourceConsumer, Level, ActiveLow, Exclusive, ,, _Y2A)
                    {
                        0x0000001E,
                    }

But can't compile, so I removed these too:

                })
                If (LEqual (GR13, One))
                {
                    CreateDwordField (SBFI, \_SB.PCI0.I2C1.TPD1._CRS._Y2A._INT, VAL3)  // _INT: Interrupts
                    Store (0x1B, VAL3)
                }

                If (LOr (LOr (LEqual (BID, 0x80), LEqual (BID, 0x82)), LEqual (BID, 0x83)))
                {
                    CreateDwordField (SBFI, \_SB.PCI0.I2C1.TPD1._CRS._Y2A._INT, VAL4)  // _INT: Interrupts
                    Store (0x1A, VAL4)
                }

Then compiled SSDT-TPD1.aml success (below attached files), put this SSDT-TPD1.aml in OC/ACPI and add to config.plist. Reboot and nothing change

Trackpad work like mouse, no gestures but Trackpad setting not show in system preferences, and nothing advance setting for trackpad in BIOS. Battery status + brighter slide working well

In IOReg, TPD1 show Interrupt mode is APIC, and can't see GPI0 - which I understand no need for Broadwell CPU right?

What were I missing? thank and regards!

with this ssdt + ssdt tpd1, and patches config, GPI0 exist and interrupt mode Polling, but in acpi-device show "i2c IOACPIPlatformDevice is not serializable", maybe it is reason?

There are two VoodooI2C operation modes available in TPD1 Device: Interrupt (APIC) and Polling.
Apply the SSDT below and reboot.

SSDT-TPD1.aml.zip

Also, Interrupt (GPIO) mode is not available on Intel 5th Gen Broadwell CPU systems.

Therefore, there is no need to enable _STA of GPI0 Device.

And, disable or delete the Rename _STA to XSTA patch of GPI0 Device.

Additionally, "IOACPIPlatformDevice is not serializable" doesn't seem to have anything to do with the current touchpad not working.

I'm noticing from your Linux dmesg output that "hid-rmi" is used, so it may be worth trying VoodooRMI in place of VoodooI2CHID. I'm not seeing the Event Driver attach for precision trackpads so I'm guessing that it's not a generic HID trackpad, but a Synaptics device which uses RMI4. The APIC pin looks like it should work, I'm not sure why your original SSDT-TPD1.aml gets rid of that pin. Your right that you shouldn't need to do anything with the pin. I would try without the SSDT + patches when using VoodooRMI.

Your mean patch 10 + 11 should disable? I confused with _STA of GPI0, where?

after tried you TPD1 with disable Rename _STA to XSTA patch, now IOReg show mode ACPI, not polling anymore, still can't detect in System Preferences panel, but trackpad still working like mouse, no guesture

thank, I trying your tip now

You need to disable patch 10 and enable patch 11.
Because _CRS Method in SSDT-TPD1.aml is used instead of _CRS in OEM DSDT, _CRS in OEM DSDT should be changed to XCRS.

I tried disable patch 10, enable patch 11 and use VoodooRMI but don't know is it working or trackpad from VoodooPS2?

and my trackpad working with some gesture on VoodooPS2, without IC2 kext.

What's benefit of trackpad when work with I2C than VoodooPS2Trackpad kext?

1Revenger1 · September 10, 2022

I2C should provide more data, giving better gestures and overall trackpad responsiveness. To make sure it's working over I2C, you could disable VoodooPS2Mouse+Trackpad to make sure it isn't interfering. If this works, then I'd try disabling patch 10, 11, and the SSDT to see if it works without. I'm fairly certain you don't need the ACPI edits.

But in guide voodooRMI required VoodooPS2Mouse+Trackpad, isnt it? That why i not sure whick Trackpad work

1Revenger1 · September 11, 2022

They are required for SMBus mode, as VoodooPS2Synaptics provides some hardware info to VoodooRMI and resets the trackpad. I2C mode does not use the PS2 drivers this way and so the PS2 drivers can be disabled. Sometimes the PS2 controller is multiplexed and has both the trackpoint and trackpad plugged into different aux ports. VoodooPS2mouse would then be needed for the trackpoint, though I don't believe this is the case here.

then the guide voodooRMI doesn't seem very clear, right?

Can you give me a needed kexts and order for voodooRMI? Thank

To make sure it's working over I2C, you could disable VoodooPS2Mouse+Trackpad to make sure it isn't interfering. If this works, then I'd try disabling patch 10, 11, and the SSDT to see if it works without. I'm fairly certain you don't need the ACPI edits.

They are required for SMBus mode, as VoodooPS2Synaptics provides some hardware info to VoodooRMI and resets the trackpad. I2C mode does not use the PS2 drivers this way and so the PS2 drivers can be disabled. Sometimes the PS2 controller is multiplexed and has both the trackpoint and trackpad plugged into different aux ports. VoodooPS2mouse would then be needed for the trackpoint, though I don't believe this is the case here.

Is I2C working now? I checked seem it work full function, except right click menu in trackpad (right click work with 2 finger tap instead), is it normally?

Looks good. Right clicking in macOS usually requires tapping or clicking with two fingers.
