BCM94352Z occasionally not recognised after a cold boot

[t_anjan]

I have the BCM94352Z card. I have followed the first post exactly (on macOS 10.12.1). The WiFi and BT work. WiFi connects to 5 Ghz networks as well. But I have found that many times, immediately after booting into the system, the WiFi device is not detected (BT always works). If I reboot, it gets detected.

I notice that this always happens after a cold-boot (booting for the first time after the laptop has been off for a while). I just reboot and the next boot always recognises the card.

When the WiFi hardware is not recognised, before rebooting, is there some log I can examine to help debug the issue?

Your ioreg shows WiFi working. Attach ioreg where it is not working.

Other comments:
- native CPU PM not implemented
- Android File Transfer is a bad idea (see FAQ)

Next reply, attach all typical "Problem Reporting" files/output.

Attach ioreg as ZIP: http://www.tonymacx86.com/audio/58368-guide-how-make-copy-ioreg.html. Please, use the IORegistryExplorer v2.1 attached to the post! DO NOT reply with an ioreg from any other version of IORegistryExplorer.app.

Provide output (in Terminal):

kextstat|grep -y acpiplat
kextstat|grep -y appleintelcpu
kextstat|grep -y applelpc
kextstat|grep -y applehda

Attach EFI/Clover folder as ZIP (press F4 at main Clover screen before collecting). Please eliminate 'themes' directory. Provide only EFI/Clover, not the entire EFI folder.

Attach output of (in Terminal):

sudo touch /System/Library/Extensions && sudo kextcache -u /

Compress all files as ZIP. Do not use external links. Attach all files using site attachments only.

- native CPU PM not implemented

I have read about it. The ssdtPRGen.sh script is not detecting my Kaby Lake CPU. I have posted an issue on the Github page. https://github.com/Piker-Alpha/ssdtPRGen.sh/issues/308. Once this is resolved, I should be able to implement the native PM.

- Android File Transfer is a bad idea (see FAQ)

Yes, I had installed it before I read that point in the FAQ. I have removed the app now.

Your ioreg shows WiFi working. Attach ioreg where it is not working.

Attached.

I don't know what has happened suddenly, but now, every time I boot in to Mac, my WiFi is not detected. The VoodooPS2Controller also seems to have stopped working (both trackpad and keyboard not working). Bluetooth still works, though!

Graphics still work too! I have disabled the "minStolen" kext patch and the Graphics properties in SysInfo still shows 1536 MB. On checking, it looks like my BIOS sets DVMT to 128MB by default.

Battery status works as well.

The IOReg I have attached has been taken in the above state.

I hope my ioreg has some clues.

You can probably fill in the values manually.
Treat it as Skylake CPU...

Did you try an EC reset?
I would work on power management before anything else.

Note: Your ioreg still shows Android File Transfer installed.
It also shows you have work to do on USB configuration (custom SSDT + USBInjectAll.kext).

You might also try without HPET/IRQ patches as they are not always needed.

Also there are some inappropriate changes in your ACPI files. Use diffmerge to review the changes you made, and I think you'll see (eg. disassemble both ACPI/patched and ACPI/origin with iasl -da -dl DSDT.aml SSDT*.aml, then use diffmerge to compare the disassembly).

I tried that, according to your guide. If I pass any parameter (for example, processor model number or frequency), it gives me an invalid argument error:

Error: Invalid argument detected: -p i5–6200U (check ssdtPRGen.sh -h)

So, I am not sure how to proceed. That is why I posted the issue on Github.

Did you try an EC reset?

I am trying to keep that as the last resort, because disconnecting the battery involves removing the back panel of the laptop.

Understood. But, as I said above, I don't know how to proceed without the ssdtPRGen script working.

Note: Your ioreg still shows Android File Transfer installed.

Yes, that is because I removed the app only after I backed up the IOReg. I will take another latest IOReg, if it would help.

It also shows you have work to do on USB configuration (custom SSDT + USBInjectAll.kext).

Also there are some inappropriate changes in your ACPI files. Use diffmerge to review the changes you made, and I think you'll see (eg. disassemble both ACPI/patched and ACPI/origin with iasl -da -dl DSDT.aml SSDT*.aml, then use diffmerge to compare the disassembly).

Could you please tell me how you detect such things, so I can detect them myself, in the IORegistryExplorer. Then, I won't have to disturb you for such obvious and mundane things. You also detected that native CPU PM is not done. How did you find that out? I am not averse to reading.

You might also try without HPET/IRQ patches as they are not always needed.

I will try rolling them back too.

Read the script to determine the actual arguments/options that can be provided.

EC reset is not really a "last resort" kind of thing.

Over time, you will learn how to use ioreg to find useful information. Unfortunately, I haven't written anything about it.

 

[t_anjan]

I think I figured out why everything stopped working correctly. I completely forgot that I recently updated the BIOS. After this, it looks like the stock, generated DSDT and SSDTs have changed significantly. So, I used the F4 method to get a fresh copy of "origin" DSDT and SSDTs and re-patched all of them. This time, I left out HPET and IRQ, like you said. Now, the Mac is back to normal.

I have also implemented the native CPU PM. It was an issue with the Kaby Lake CFG file in the GitHub repo. I have updated the issue as well.

I have not worked on the USB yet. Looks like it would take a bit of time to read through and follow it.

Also there are some inappropriate changes in your ACPI files

I have attached the relevant files again. Do you still see any inappropriate changes?

With static patching, any BIOS update, hardware update, or BIOS option change makes re-extract/re-patch compulsory.
It is one of the reasons I always hotpatch...

Sounds like you're making progress...

When you say "hot patch", do you mean using Clover's ACPI => DSDT patches?

So, I'm guessing you do not see any inappropriate changes in my DSDT and SSDTs now. And you see native CPU PM active.

My hotpatch guide is linked from my ACPI patching guide.

So, I'm guessing you do not see any inappropriate changes in my DSDT and SSDTs now. And you see native CPU PM active.

I didn't look, as you didn't really identify a problem.
