ACPIDebug no output

[kevinbai]

Problem Description
ACPIDebug failed to start, there is no output about "ACPIDebug" in "system.log"("console" -> "system.log"). After a full day of Google/Baidu, I still have no idea about this problem. So I'm here for help. Thanks for all solutions.

The Steps I Followed
I followed this guide, http://www.tonymacx86.com/yosemite-...ching-dsdt-ssdt-laptop-backlight-control.html. Below is the detail:
- install ACPIDebug.kext: https://github.com/RehabMan/OS-X-ACPI-Debug
- add the ACPIDebug repo to MaciASL "Sources" per README
- apply ""Add DSDT Debug Methods"
- apply "Instrument EC Queries"
- reboot

The Way To Confirm Patch And Kext Applied Successfully
First, I confirm the patch like this:
- in terminal, run "patchmatic -extract"
- decompile dsdt.aml and see the following info
a.
Device (RMDT)
{
Name (_HID, "RMD0000") // _HID: Hardware ID
Name (RING, Package (0x0100) {})
Mutex (RTMX, 0x00)
Name (HEAD, Zero)
Name (TAIL, Zero)
Method (PUSH, 1, NotSerialized)
{
Acquire (RTMX, 0xFFFF)
Add (HEAD, One, Local0)
If (LGreaterEqual (Local0, SizeOf (RING)))
{
Store (Zero, Local0)
}

If (LNotEqual (Local0, TAIL))
{
Store (Arg0, Index (RING, HEAD))
Store (Local0, HEAD)
}

Release (RTMX)
Notify (RMDT, 0x80)
}

...
}
b.
Method (_Q1D, 0, NotSerialized) // _Qxx: EC Query
{
\RMDT.P1 ("EC _Q1D enter")
PCLK ()
\RMDT.P1 ("EC _Q1D exit")
}
...

Therefore, I think patch is OK.

Second, I confirm kext loaded by doing this:
- in terminal, run "dbmesg > t.txt"
- in t.txt I can see:
3:975 0:001 Preparing kexts injection for arch=x86_64 from EFI\CLOVER\kexts\Other
3:975 0:000 Extra kext: EFI\CLOVER\kexts\Other\FakeSMC.kext
3:995 0:020 Extra kext: EFI\CLOVER\kexts\Other\RealtekRTL8111.kext
4:032 0:036 Extra kext: EFI\CLOVER\kexts\Other\VoodooPS2Controller.kext
4:047 0:015 Extra PlugIn kext: EFI\CLOVER\kexts\Other\VoodooPS2Controller.kext\Contents\PlugIns\VoodooPS2Keyboard.kext
4:063 0:016 Extra PlugIn kext: EFI\CLOVER\kexts\Other\VoodooPS2Controller.kext\Contents\PlugIns\VoodooPS2Mouse.kext
4:064 0:000 Extra PlugIn kext: EFI\CLOVER\kexts\Other\VoodooPS2Controller.kext\Contents\PlugIns\VoodooPS2Trackpad.kext
4:074 0:010 Extra kext: EFI\CLOVER\kexts\Other\ACPIDebug.kext

Therefore, ACPIDebug is also loaded successfully.

Unfortunately, The ACPIDebug is still not working. Thanks for all answers.

Sorry for my poor English!

Keep in mind new system logging in Sierra (/var/log/system.log no longer used). Read Apple developer documentation for details.

You can verify ACPIDebug is loading by looking at ioreg.

Nice, after running "log show --last 5" in terminal, I see some messages about ACPIDebug.
So excited.
Thank you very much!

I know this is an old topic, but I had the same problem on Mojave. I found a solution to be building from source after setting the target to "MacOS" rather than "macos10.8" (or whatever)... once built (and you can find the derived files)... you can install the kext to /Library/Extensions/.

Another tip to view the logs is to use this "log show" command:

log show --predicate 'processID == 0 && eventMessage CONTAINS[c] "ACPIDebug"' --start 2019-04-22 --debug

This will give the color-formatted output.

If I get time I might submit a PR to update the project, or even the built binaries.

Cheers!

*UPDATE: Although this seems to show the ACPIDebug messages appearing in the log, I'm actually still not seeing any logs when I add some \RMDT.PUSH("...") statements in the DSDT.aml compiled code. I'm verifying the DSDT changes are loaded with IOExplorer as well. I'll be digging into this more tonight. I might start a new topic where I can provide more details (and have updated profile info for aid with debugging)

**UPDATE 2: I can confirm with some certainty that the debug logging works intermittently. I will either get no logging, or full logging. I suspect it may have something to with the loading order of the kexts. I might play with this some more.

Any update here? I'm working on some DSDT changes and I'm getting a bit confused at this point as to whether it's running at all.
