Cpustscsync maybe broken on macOS Monterey #1676

reynan2020 · 2021-06-10T02:40:01Z

Kernel panics and can't boot to macOS Monterey without using cpus=1 boot flag.
Some times it is stucked at Appleacpicpu processor "" local apic "" when booting the installer.

I do clean install and followed dortania's guide, still the problem exist. CPUTSCSync works on macOS Big Sur with oc 7.1 but broken on macOS monterey
Tried using VoodooTSCSync, it didn't work.
Asus X409UA, Intel Core i3-7020U.

Try adding cpus=1 boot flag to NVRAM. I can boot with it but using only 1 cpu core out of 4 cores. I checked it and I have the same problem with you.

I’m not into installing betas yet, sadly. Just tried to get an idea whether it had any problems.

Also, does it need to stay cpus=1 after install? If so, it's not an option for me.

Yes, before and after install. You should add it and not remove that boot flag (macOS Monterey) until they fixed the issue.

Thanks for the info. I’ll try to gather logs in the end of the month if noone does it first as now I have no time tinkering with my pc.

I can actually boot with CpuTscSync.kext, but I will have panic about non-monotonic time, if i put laptop in sleep mode and then let it wake after some time (it can wake 2 or 3 times with no panic, or can`t wake even for 1st time). I am sure, that's panic caused by that kext, because if I remove it from config > no panic will happen. I will add panic log info here, once it get it again.

Btw, it can randomly stuck in same place as guys above have already mentioned (AppleACPICPU stuck)

I encountered the same problem with detailed debug log.

notluquis · 2021-06-20T03:12:40Z

Same problem here with ASUS S14 X411UF, and I can only boot with cpus=1 flags, without SMCProcessor kext and with cputscsync. Here is my EFI. If anyone knows, take a look of my EFI and compare haha (or if I missing some Kext, ACPI file or option on my config file.)

anonymous-writer · 2021-06-20T12:52:10Z

With these settings processor frequency stays at max.

Currently the only option for BugSur and Monterrey for me here.

Under BigSur no problems. Under Monterey tsc stop after sleep.

Beta 2 does not solve the problem. For me still only TSCAdjustReset.kext works under Monterey. After Sleep TSC sync broken.

vit9696 · 2021-06-29T20:53:27Z

Just to make it clear, nobody uses this kext or macOS 12 from the core team. Thus nobody explored it. You are best to submit a PR with a fix.

anonymous-writer · 2021-06-30T06:16:23Z

Fix would be TSCAdjustReset.kext. The problem is that this kext loses its function after sleep under Monterey.
Unfortunately I don't know how to fix that. On BigSur, this kext also works after Sleep.

@vit9696 it doesn't make it insignificant though. TSC synchronization affects all Kaby Lake CPUs, there're plenty of people who still use it. As macOS 12 becomes official (not beta) you'll be overwhelmed by similar issues here if you don't fix CPUTSCSync because it is in acidanthera repositories. The latest commit with the new constants doesn't fix the problem, I tried to compile.

I think we can all agree that CpuTscSync is way better than TSCAdjustReset, it's more advanced, in my case, CpuTscSync can boot successfully with Monterey, however, when waking from the screen becomes black and unresponsive, similar to how it would be without it, if the laptop wakes without CpuTscSync it also becomes very laggy and useless.
I'm pretty sure most of us are ready to troubleshoot until we can this fixed before it officially launches sometime in November.
Thanks

Absolutly you are right
CpuTscSync is better than TSCAdjustReset
I agree that without CpuTscSync.kext the kabylake system is very laggy and useless after wake from sleep on macOS Big Sur
Unfortunatly waking from the screen becomes black on macOS 12
I don't know confirm due to CpuTscSync.kext or bug of macOS 12 beta 2

@vit9696 I tried to compile that kext you mentioned in the reference, but I’m getting two errors about missing files (I’m not in front of the computer now, where I took a screenshot). And yes, I have Lilu debug in the correct folder. Maybe you know what it is. Do I need something in particular besides Lilu and Xcode?

Well, ‘powernap’ feature, or better call it the darkwake, seems to not working with the same kernel panic if the machine manages to enter darkwake state. Will gather logs with keepsyms=1 later, as now I’m testing a workaround for my laptop specific model (syncing tsc is not needed at all with lower bios firmware)

Where is the panic log?

Can you share this latest driver？

Ubsefor · 2021-07-19T09:21:05Z

Where is the panic log?

Here it is, but it’s without keepsyms, so it’s kinda useless… At least from what I can tell it is awfully similar to earlier kps after sleep.
I will attach the log with keepsyms=1 a bit later.

Hi @vit9696, it appears that CpuTscSync is attached to AppleACPICPU under CPU@0 instead of the last CPU (in my case CPU@3), I tried to attach my KP log but I can't boot to my Monterey Disk anymore and I don't know why, I took a copy of IOReg before restarting, hope it helps. (@ameenjuz do you have the same issue as mine since we have the same laptop model? And is it different in Clover?)

The reason why the Xeon Cpu cannot be synchronized may be related to the new power management driver. After entering the firmware ssdt, I found that the power management uses com.apple.driver.ACPI_SMC_PlatformPlugin for management, of course My machine can't work normally. The cpu frequency only recognizes 2.38hz, and it restarts once a minute or so, and the complete kext loaded by the system is attached.

lvs1974 · 2021-08-03T10:14:23Z

@ameenjuz: it is correct behaviour for macOS 12, tsc adjust is executed when the last cpu is available in ACPI.

mishurov · 2021-08-03T10:26:06Z

@lvs1974 when I tested on my laptop, during the boot process for me it was sufficient just to reset MSR_IA32_TSC_ADJUST on the first core CPU0 without even waiting for other cores or executing mp_rendezvous_no_intrs. Can't say about sleeping though. I didn't know about IOHibernateSystemWake() Lilu routing at the time.

I recently started using CpuTscSync on Skylake laptop in monterey
It is because of the phenomenon that it does not drop below 1.5 GHz at any moment and it continues to be higher than that. I used CpuTscSync and this problem went away.
I used a file that was committed two days ago, but strangely, when I press the restart button after turning on Chrome, the Chrome does not respond.

no problem

This may be helpful for the TSC repair of e5-26xx series cpu. This is the cpu detailed information obtained using msr-tool under centos.

I believe the recent updates to CpuTscSync and Lilu fix most of the issues. Let's raise another issue if there are more.

rishsharma · 2021-11-21T02:16:15Z

FWIW, I tried with updated kexts and OpenCore 0.75 on a p8p67 pro and still get this same issue. Let me know if I can provide any details.

gulios · 2021-12-18T18:50:02Z

Asus UX430AU i7-7500U
Open Core 0.7.7
CpuTscSync 1.0.5
On BigSur it worked fine. After Monterey getting random KP on wake up(black screen, fans spining. Only hard reset to boot again)
All kexts are up2date.

@vit9696 can you check it please?

Thank you

I have the same error

sushilei · 2022-01-10T11:41:46Z

@gulios did you solve this problem

gulios · 2022-01-10T11:50:21Z

no, still random KP on wake up.
Maybe @vit9696 will help with this.

#1900

paulotex · 2022-06-21T09:19:49Z

Report on this issue on a X299 with a i9-9940X: It was still giving me a non-monotonic time KP with version 1.0.5 and with kernel option TSC_sync_margin=0. My machine sleeps every evening, and I was getting this KP once or twice a week. But with the latest version 1.0.6 the issue seems to be solved. I am now on day 6 without a KP. I still use the kernel boot option TSC_sync_margin=0.

Thanks for the good work guys!

BillDH2k · 2022-11-05T20:08:16Z

vit9696 commented [on Jul 17, 2021] (#1676 (comment)). [on booting issue]:

Well, the situation unpleasant. The root cause of the issue is that on macOS 12 CPU registration comes in parallel with many other things, so SMP support (hardware multithreading) is initialised even before all the CPU cores are initialised.

Normally the solution is to wait for all CPUs to register, then perform the TSC sync on them. Now it is no longer feasible, since whenever even just 2 CPUs register, we already have multithreading and potentially a kernel panic. I am not quite sure how to address it best.

@vit9696 For systems unable to boot under Monterey due to TSC out of sync, here is a solution worked for my setup (DELL T5810, X99, Hanswell-E/Broadwell-E Xeon): Perform a TSC Reset, with this efi tool ResetTSCAdjust.efi [link], during OC booting, before launching macOS. May be OC could consider add this tool as an option. Or may be built in and perform this command automatically. This could overcome systems with their BIOS not reset TSC properly on boot up.
