ACPI Error _CPC not found

[Chris]

just recently (I guess since the last update) I get a few ACPI error messages during start up. Those are also visible with dmesg:

Searching the internet shows that many people with different computers are affected by that.

Probably it's a regression in the Linux kernel as described at: https://bugzilla.kernel.org/show_bug.cgi?id=213023

I'm having the exact same problem with Acer Aspire 5 A515-51-51UX, and the problem just appears with the latest kernel. If I use LTS kernel this acpi problem doesn't appear anymore. I will show my acpidump later when I finish installing arch on it.

Do you mean latest stable kernel 5.12.4?

yes the latest stable kernel.

[bugs (bugs-linux-kernel-bugs)]

As long as no kernel maintainer answers, our confirmations are not of much use. Because it concerns acpi, it is probably ignored. Only version 5.11.xx is not affected yet.
Maybe there will be a patch after all. In 5.12.5 from 19.05.21 is still the same error.

[fkrueger (fkrueger-linux-kernel-bugs)]

Maybe the linux-kernel list is more appropriate: https://marc.info/?l=linux-kernel&r=1&b=202105&w=2. Anyway, cc'ing Hans de Goede (@redhat), who might have an idea what's going on here.

[jwrdegoede (jwrdegoede-linux-kernel-bugs)]

These kind of errors typically indicate that there is a bug in your ACPI tables (so this is a BIOS bug not a Linux bug). This is also why there are prefixed with: "ACPI BIOS Error (bug)".

Can people who are seeing this please attach an acpidump of their system here ?

ACPIDUMP + DMESG outputs for linux and linux-lts

I am now providing ACPIDUMP and the output of 'sudo dmesg | grep ACPI > file' for both LTS and mainstream kernels, with latest updates from Arch Linux stable. Why did I provided two ACPIDUMP's? for some reason, the output of acpidump command is different between these kernels.
Since there's 4 files, i'm creating a .zip containing everything.
The laptop is an Acer Aspire 5 A515-51-51UX.

Yes, that is known. But nevertheless there must be a difference in the query to kernel 5.11.x, because there this error message is not present.

On my desktop with ryzen 1600AF + asus ex-a320m-gaming, these acpi errors didn't appear, but on my work computer it does too. both my laptop and work computer shows these acpi errors and those have intel CPU's. maybe it's an intel-related stuff

Ok, so I've removed the timestamps from the 2 dmesg logs attached by Paulo Marcos and then ran a diff -u, after that I edited out some (non-relevant) memory-address differences and did a second diff -u, this results in this:

(there are other differences later during boots, but these are the ones which count).

So for some reason the kernel is no longer loading the Cpu0Hwp and HwpLvt SSDT-s, and that is causing these errors.

So you mean you are seeing the "Could not resolve symbol [\_PR.CPU0._CPC]" errors with 5.10.35, correct ? That is interesting because for Paulo Marcos these errors are no happening with 5.10.38 . Can you perhaps give 5.10.38 a try ?

A suspect that this may have something to do with these 2 commits:

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=6998a8800d73116187aad542391ce3b2dd0f9e30

Can someone who is seeing this try building a 5.12 kernel with these 2 commits reverted please? Note you should revert the 6998a8800d73116187aad commit first.

I will compile this kernel right now by installing linux-git package (arch linux)

If I apply one patch, the other one refuses to apply itself. I'm applying the first one to see if there's any difference

The same error with both commits and 5.12.9 too.
The LTS 5.10.42 works ok without ACPI errors.

[contato-myghi63 (contato-myghi63-linux-kernel-bugs)]

I tried to compile and install the linux (git, since these commits are for 5.13-rc5 kernel) with these commits reversed, but I had no success while installing it (make modules_install was complaining about missing stuff, even if I install without the patches), so I coudn't test it.
But anyway I tried the latest LTS and stable kernels (5.10.42 and 5.12.9) and the stable one tells me the same ACPI errors, while LTS don't.

[jwrdegoede (jwrdegoede-linux-kernel-bugs)]

Good news, a very similar bug is being tracked here:

https://bugzilla.redhat.com/show_bug.cgi?id=1963717

And one of the reporters there has done a git bisect and has found the commit which is causing the problem for them:

"""
git-bisect points to 719e1f561afbe020ed175825a9bd25ed62ed1697 :
"ACPI: Execute platform _OSC also with query bit clear".

Tested 5.12.9 kernel with the commit reverted, and confirmed that the error

Can some one seeing the "Could not resolve symbol [\_PR.CPU0._CPC]" error try building a 5.12 kernel with the 719e1f561afbe020ed175825a9bd25ed62ed1697 commit reverted and see of that helps please?

[jwrdegoede (jwrdegoede-linux-kernel-bugs)]

Note as mentioned in the quoted comment to revert 719e1f561afbe020ed175825a9bd25ed62ed1697 you first need to revert 5a6a2c0f0f43676df27632d657a3f18b151a7ef8

So after doing a clean checkout of the 5.12.y branch you need to run:

git revert 5a6a2c0f0f43676df27632d657a3f18b151a7ef8
git revert 719e1f561afbe020ed175825a9bd25ed62ed1697

And then build + install the kernel after that.

Apparently, the bug still persists for me. Using vanilla linux kernel 5.15.12 compiled from source on my Gentoo on Thinkpad T440s.

This is not good. The patch does eliminate the error messages for me, but it also disables CPPC on my system.

My board is ASRock H470 Phantom Gaming 4, BIOS L1.12 12/04/2020.

The board bios has a config for "Intel Speed Shift Technology". The user manual says this about it:

"Enable/Disable Intel Speed Shift Technology support. Enabling will expose the CPPC v2 interface to allow for hardware controlled P-sates."

When I first got the error messages with 5.12.6 last year, I confirmed that the error messages disappears with CPPC v2 option disabled. But disabling CPPC v2 support is not a way to go, I guess?

I believe ASRock B460M also supports CPPCv2.

I mentioned the same observation in Bug 216070 that acpi_cppc interface is gone. I just looked my ASRock B460M-ITX's firmware settings. You are right, the option "Enable/Disable Intel Speed Shift Technology support" has the same help message.

But I don't know if the bug / current fix disables any function that had worked before. Based on various online resources, my understanding is "Intel Speed Shift" = HWP (Hardware P-state) in Linux, and I can see kernel message say it always works (intel_pstate: HWP enabled).

I can confirm /sys/devices/system/cpu/cpuX/acpi_cppc/ exists before 5.17.2 when the error hadn't been introduced. But I don't know if things in it were actually usable. Is there anything I can do to test if CPPCv2 works on old kernels?

I run the system with 5.18.10 with the original patch (the reverted one) applied.

It has /sys/devices/system/cpu/cpu0/acpi_cppc entry. But, no, I am not sure if CPPCv2 is actually working or not. ouch.

This patch also disables CPPC support on a few of my relatively recent AMD Zen Desktop systems. The issue is that the ACPI _OSC method supports ONLY the UUID of the "PCI root bridge device", but not any other, but linux is looking for CPPC support with the "Platform-Wide OSPM Capabilities" uuid, which does not
exist anywhere in the firmware. bios engineers told me that this is all part of AMDs AGESA thingie, and they won't be able to add support for this, at least
on current (i.e. zen3-supporting) platforms.

Could this be worked around, by first checking whether any _CPC objects exist, and maybe a matching PCC entry?

All the known issues from CPPC and _OSC with AMD should be fixed for 5.19-rc8. If you still have one with Zen open a new issue.

The remaining issue is that reportedly from this thread a number of Intel systems the firmware will mask the _OSC during negotiation. When the _OSC is masked a dynamic SSDT doesn't get loaded.

Someone needs to confirm if:
* This is intended behavior that firmware masks the _OSC (and thus CPPC v2 shouldn't be used on these systems).
or
* This is purely a firmware bug and CPPC v2 should be used and that should be quirked when the _OSC is evaluated on the affected systems (or later so the SSDT still loads).

I have a similar error " [\_PR.CPU0._CPC], AE_NOT_FOUND ".
I don't expect that kernel will always compatible with my ACPI.
Because now that's my second array mismatch error.
The problem is that, based on the error above, I don't know which module I need disable.
At least until the new kernel will updated.
I can only off the entire ACPI or ignore the error.

Question.
- I suppose when I will have old equipment I will have more errors.
Can I count on being able to disable what doesn't work with the kernel table in the future?
I need an extra message / information on how / what I can turn this off.

The only solution worked for me was to re-install same version of ubuntu into same partition.
If you UNCHECK 'Format' option on installation process, your personal files will survive after re-installation.

It is January 2023 now, and this bug is still active in kernel 5.15.86. :(

I am running KDE Neon with self compiled kernel 5.15.x (because it is marked as "longterm") on a Fujitsu mainboard, equipped with an Intel Core i5. (See below.)

I wouldn't mind having these messages in the systemlog, as they are harmless and the system runs without any quirk. But but they appear on the console as well, even interrupting the splash screen! (Which is a bit of a humiliation, if there's a Windows user looking over your shoulder while your machine is booting...)

I know that this is a pure cosmetic complain, but it has been happening for more than a year now, and I really would like to get rid of this annoyance. I tried the usual grub command line options like

"loglevel=3"

"acpi_osi=! \"acpi_osi=Windows 2015\""

but neither did suppress these console messages.

Can you please try with an upstream kernel? Being a distro kernel, it's very possible they're missing some of these patches.

Hi,

Thanks for the suggestion. I tried the upstream 5.4.0-144 and also saw there's a newer version 5.4.0-145, so I tried that one as well, but the issue still persist.

Can you try a newer kernel outside the 5.4 series? Perhaps the latest LTS kernel, 6.1?

Hi, got this again after a Ubuntu update that overwrote my "acpi=off" grub kernel parameter. For anyone that can't boot into the login screen then adding this is the fix.

CPU: Q9650

BTW the last half of the reports below are after I hit the power button to initiate what would normally be an ACPI shut down. I had to keep the power button held down to force power off.

I'd like to report one more instance of this bug. BUT perhaps more importantly pass on a condition that seems to trigger these ACPI errors at boot time (which you may or may not realize) and which might affect your continued approach to fixing.

I use an old Dell t7400 and just recently decided to activate their TPM (trusted platform module) in my bios. I had never received any of these boot ACPI errors until I activated the TPM (which uses the broadcom LAN chip for crypto key generation).

Immediately after activation, the ACPI errors unique to my system were reported at boot through dmesg. Upon deactivation AND DISABLING the TPM function (there are 2 distinct steps needed) the boot time ACPI errors cease being reported.
