Kernel panic on 2015 AMD 15" rMBP + Catalina 10.15.5
Funny how right after my last issue #11 where I said "I haven't kernel panicked", I got one just 2 hours later. Heh.
Was messing around with the turbo ratio limits (said rate in the other issue, whoops), and after a few minutes of my last setting, my rMBP rebooted. I have the log this time (previous panic had no log or dialog). I also caught ytop giving an error pointing to a memory allocation issue right before the panic froze my machine, and as the kernel log confirms it's most likely a memory leak. Looks like changing CPUTune settings on the fly won't be an option for the time being.
Log start:
panic(cpu 2 caller 0xffffff800c977801): "zalloc: zone map exhausted while allocating from zone kalloc.80, likely due to memory leak in zone kalloc.80 (5923135920 total bytes, 74039199 elements allocated)"@/AppleInternal/BuildRoot/Library/Caches/com.apple.xbs/Sources/xnu/xnu-6153.121.2/osfmk/kern/zalloc.c:3559

No problem. Do you have any idea which feature could be causing this issue and if I can disable it for now to try and continue using CPUTune without the panics?
@JJGadgets how about commented out some code path in the readConfigAtRuntime then compile it and give it a try?
Hi @syscl ,
I am encountering the exact same crash/memory leak as the original poster.
I tried deleting all of the code for non-turboboost features, (lines 175-234 in CPUTune.cpp) but it still causes kernel panic after about an hour.
So it seems like the memory leak is in readFileAsBytes().
Thank you!
@jamesmurdza would you mind try the latest version? and also commented out readConfigAtRuntime?
When I comment out everything in readConfigAtRuntime the leak does not happen. This is in the latest version (2.2.5).
I recently upgraded from 1.9.0 to 2.2.1 which is when I first noticed the leak (zalloc). The leak also happens with the old readFileNBytes function and when commenting out all the readConfig code except for turbo boost.
@jamesmurdza would you mind try the latest version? and also commented out readConfigAtRuntime?
I will do this over the weekend hopefully, been a bit behind in a couple projects at school. I've been disabling BD PROCHOT and assigning max turbo ratios using VoltageShift's manual MSR overwrite function (so that I don't get weird short but noticeable bursts of throttling even at ~65C while doing project research), but of course if I could do it from CPUTune that'd be great.
Side note, is there any way for the CPU to still throttle despite disabling BD PROCHOT apart from T-Junction shutdown (100C for a 4870HQ)? Seems like unless I force the frequency like I did on Windows + ThrottleStop, there's still some other throttling that occurs rarely (can't pinpoint cause).
@JJGadgets currently you may need to do the code change. I think the problems happened at the readConfigAtRuntime function .
Thanks @jamesmurdza! Which old version also has the leak you've mentioned?
Hi @syscl — That's what I would like to know as well! I will do some tests and get back to you.
Hi @syscl, the problem seems to be related to the timer. This new code causes a memory leak:
if (timerSource && !this->isInactive()) {
// Don't use sender here which will cause MBP8,2(SANDYBRIDGE) KP
timerSource->setTimeout(updateInterval);
}
Whereas this does not:
sender->setTimeoutMS(updateInterval);
Do you have an idea what the reason could be?
@jamesmurdza nice catch! timerSource was used due to sender will cause MBP8,2(SANDYBRIDGE) kernel panic. I also a little bit confused about what's the difference between sender->setTimeoutMS(updateInterval); and timerSource->setTimeout(updateInterval).
But as you pointed out, could you try to use sender->setTimeoutMS(updateInterval); to see if there's no more memory leak?
Thanks in advance!
@syscl yay I think it just fixed my kp on MBP2017 non-touchbar which due to memory leak; now I can run smoothly with HWP tweak without battery on catalina;
What I did notice is timerSource making my CPU always 100%
although memory leak doesn't happen anymore, but the cpu somehow still capped at 1.5 Ghz, BD_PROCHOT option does not effect on my bad battery @christophe-duc plz help me
@syscl the difference between sender->setTimeoutMS(updateInterval); and timerSource->setTimeout(updateInterval). is MS :3 It should be timerSource->setTimeoutMS(updateInterval)
@syscl the difference between sender->setTimeoutMS(updateInterval); and timerSource->setTimeout(updateInterval). is
MS:3 It should betimerSource->setTimeoutMS(updateInterval)
@sooxt98 Good catch. It looks like setTimeout() defaults to nanoseconds instead of milliseconds. Default UpdateInterval is 1000, so instead of pausing for one second it would be pausing for one microsecond. The lack of any delay could be contributing to the memory leak. Does that seem logical?
@jamesmurdza if you read the link, the setTimeout default timeout is in nanoseconds which makes the read config going crazy. https://developer.apple.com/documentation/kernel/iotimereventsource/1809617-settimeout
@sooxt98 Thanks for point it out, I corrected the setTimeout to setTimeoutMS. Let me know if this fix the issue! cc also @jamesmurdza
In the meantime, I don't know if it is my laptop's issue, I cannot generate CPUTuneCore.kext on my laptop, any idea? Sorry for the late reply since I'm on call this week.
@syscl i does fix the issue; try to delete your build folder manually at ~/Library/Developer/Xcode/DerivedData
Thanks @sooxt98 , I removed ~/Library/Developer/Xcode/DerivedData and compiled but still cannot see CPUTuneCore.kext. Can you see the latest CPUTuneCore.kext?
@syscl the build kext should appears inside the ~/Library/Developer/Xcode/DerivedData
