Tried using your kext on apple's new beta with mbp2019 16inch.

[syscl]

Thanks for the report! Will take a look!

[syscl]

@nk2IsHere I saw the version you are using is 2.1.7, could you try to build a latest 2.2.1 and see if it work with 11.0?

[syscl]

In the meantime, could you please give v2.2.3 a try which attempt to fix the memory leak in your case. Thanks in advance!

[nk2IsHere]

Unfortunately, it does not compile anymore on Xcode-beta 3:

/Users/nk2/Desktop/CPUTune/CPUTuneCore/CPUTune/kern_util.hpp:109:10: Conflicting types for 'kern_os_free'

[nk2IsHere]

Commenting out line 107 in kern_util.hpp: void kern_os_free(void* addr, size_t nsize);
And casting void* to uint8_t* in kern_util.cpp: buffer = (uint8_t*) kern_os_malloc(sizeof(uint8_t) * (bytes + 1));
Seems to fix compiling error, will give more info when I'll start my system with this kext.

[syscl]

Thanks for pointing out! Feel free to give the latest version a try!

[nk2IsHere]

I've built the latest version you've provided.
Unfortunately, it still crashes

If you need more info on this crash, I'll be happy to provide it

[syscl]

Thanks! When did the kext crash? Crashed when wake up from sleep or even failed to load?

[syscl]

An also, I would like to know what's the config you set for CPUTune.kext

[nk2IsHere]

This kext is crashing on system boot.
I did not change any prefs in kext, though I will provide defaults below.

[syscl]

@nk2IsHere I mean did you create some config in /tmp? For example change the rate limit via /tmp/TurboRateLimit.conf?

[nk2IsHere]

No, I didn't create any configs in /tmp
The kext does not load properly and causes kernel panic on system boot, so I can't even start macOS to test things
Edit: to clarify more, I've installed kext, rebooted, and got panic (nothing's changed, no files were created)

[syscl]

@nk2IsHere Thanks. I would suggest try to load kext first before install it. Just curious how you install the kext on 11.0? IIRC, there's not allowed to install kext on 11.0 easily.

[nk2IsHere]

I've disabled secure boot and sip and then I've just pasted it to /S/L/E and rebuilt caches using this utility.
(And added -v -cputbeta to boot-args)

Actually, I can boot a system with CPUTune only if I remove -cputbeta from boot args, but the kext will stay disabled.

I can't for some unknown reasons load kexts in macOS 11 (I think it is related to codesigning)
Here's the example of me trying to load CPUTune using cli tools:

➜  Desktop sudo kextload CPUTuneCore.kext 
Executing: /usr/bin/kmutil load -p /Users/nk2/Desktop/CPUTuneCore.kext
Error: Error Domain=KMErrorDomain Code=1 "Unable to stage extension: KernelExtension org.syscl.driver.CPUTune v2.2.4 in bundle at /private/var/db/KernelExtensionManagement/Staging/org.syscl.driver.CPUTune.ukc1y1/CPUTuneCore.kext is either invalid or inauthentic." UserInfo={NSLocalizedDescription=Unable to stage extension: KernelExtension org.syscl.driver.CPUTune v2.2.4 in bundle at /private/var/db/KernelExtensionManagement/Staging/org.syscl.driver.CPUTune.ukc1y1/CPUTuneCore.kext is either invalid or inauthentic.}

[syscl]

I see, so the kext cannot be loaded via kmutil due to the signature issue.

Hi,

Is it possible to use CPUTune on MacOS BigSur Beta 10?

Is there a version of CPUTune already compiled for Download, Or some kind of tutorial on how to compile the source code by XCODE?

Tks.
