Doesn't work on Surface Laptop Go, even though SSDT is installed.

[carloskips]

Hey, I am 99% sure I installed this correctly, I added the SSDT, added all the "sub-kexts" and ordered them correctly. The trackpad still works, gestures don't. Or any of the other added features. It basically just acts like VoodoI2C and randomly causes kernel panics, in the os and on the boot screen. I was following the guide made by olm3ca, and it uses this kext. Yet it doesn't add any of the features. Is there something I am missing in the configuration? Thanks in advance.

[Xiashangning]

First of all, what is not working when you don't use BigSurface? (What do you expect this driver to drive) I am not clear about the hardware on Surface Laptop Go.

[carloskips]

Battery percentage, trackpad gestures and sleep.

[Xiashangning]

I need the kernel panic logs (need boot-args keepsyms=1) and your ioreg file.

[Xiashangning]

BigSurface has nothing to do with sleep issues, that is related to ACPI or Opencore's config As for trackpad and battery, it should work since you are on intel 10th platform Send me your ioreg file

[carloskips]

Here's my IOReg file and the .panic file. Logs.zip

This is your extracted kp log, as you can see, it has nothing to do with BigSurface, this is your own installation's problem

[carloskips]

OK, I can resolve that, how about the other issue?

[Xiashangning]

Add DebugEnhancer.kext and send me output of sudo dmesg | grep -E "SurfaceSerial|VoodooUART"

[Xiashangning]

And of course use the latest version of BigSurface

[carloskips]

Here's the output:

[    0.646259]: VoodooUARTController::UA00 device id: 34a8

[Xiashangning]

Impossible, do you have BigSurface.kext enabled in config.plist?

[carloskips]

image All of them.

[carloskips]

The SSDT too. image

[Xiashangning]

Does your BigSurface version up to date?

[carloskips]

Latest one, 6.0.

[Xiashangning]

Try again with this sudo dmesg | grep -E "SurfaceSerial|VoodooUART"

[carloskips]

Still [ 0.646259]: VoodooUARTController::UA00 device id: 34a8

[Xiashangning]

Send me your BigSurface.kext

[carloskips]

BigSurface.kext.zip

[Xiashangning]

What about the new ioreg?

[carloskips]

CMacBook Air.zip

[Xiashangning]

There is definitely something wrong on your config. There must have a log like this VoodooUARTController::UA00 Designware UART version.... This line is written in the start function, so if VoodooUART shows up in ioreg that means start function returns no error. Thus this line will be executed.

[carloskips]

I am so sorry, I though the UART id was the only relevant piece of information, here's the rest.

[    0.646491]: VoodooUARTController::UA00 Designware UART version 3.14
[    0.646497]: VoodooUARTController::UA00 Too bad that we can only use timer

[Xiashangning]

...

[carloskips]

I am so sorry for the inconvenience, I don't know why I thought that.

[Xiashangning]

Use this one and send me all output of sudo dmesg | grep SurfaceSerial BigSurface.kext.zip

[carloskips]

[ 0.611936]: Couldn't alloc class "SurfaceSerialHubDriver"

[Xiashangning]

BigSurface.kext.zip

[carloskips]

Unfortunately still [ 1.272416]: Couldn't alloc class "SurfaceSerialHubDriver"

[Xiashangning]

I need full log of sudo dmesg then But be aware that the possibility of resolving this by me is nearly 0. I am afraid that it falls into your "1% case of wrong installment". This is more likely a OC config problem to me, since this type of error only happens when macOS cannot find the class --"SurfaceSerialHubDriver" described in Info.plist of a kext -- BigSurface.kext in this case. However, this class definitely exists, because the same kext works on all other devices. at least not with this problem.

[carloskips]

Sorry for the late reply, here is the full sudo dmesg output log.

[Xiashangning]

There contains no SurfaceSerialHubDriver in your log...

[carloskips]

I'm very confused as to why it's not there. I have the kext enabled in my plist. image

[Xiashangning]

So do i...

[Xiashangning]

Well, now 100% sure it is your own problem, see issue #40 for a "normal" output of Surface Laptop Go. Battery is proved to be working, I don't know what happened to your device.

[IsaahE]

It's not working for me either in this exact way. Installed exactly how it says and quadruple checked everything. I have the SSDT and Kext installed and the kexts are configured in the right order. Laptop acts exactly the same with and without BigSurface.kext
