Fix TPM chip hanging system before suspend/shutdown

Fix hanging before shutdown/suspend behaviour on some buggy platform firmwares.

Adam Alves (1):
Some buggy firmwares might require the TPM device to be in default
locality (Locality 0) before suspend or shutdown. Failing to do so would leave the system in a hanged state before sleep or power off (after “reboot: Power down” message). Such is the case for the ASUSTeK COMPUTER INC. TUF GAMING B460M-PLUS board, I believe this might be the case for several other boards based on the bugs I have found on the internet while trying to find out how to fix my specific issue. Most forums suggest the user to disable the TPM device on firmware BIOS in order to work around this specific issue, which disables several nice security features provided by TPM, such as secure boot attestation, automatic decryption and hardware random generator.

2.44.0

My PC would hang on almost every shutdown/suspend until I started testing this patch and so far in the past week I haven’t experienced any problems anymore.

I suspect that the root cause on my specific board is that after the ACPI command to put the device to S3 or S5, some firmware application/driver will try to use the TPM chip expecting it to be in Locality 0 as expected by TCG PC Client Platform Firmware Profile Version 1.06 Revision 52 (3.1.1 – Pre-OS Environment) and then when it fails to do so it simply halts the whole system.

This issue might be related to the following bug:
https://bugzilla.kernel.org/show_bug.cgi?id=217890

Enable a user to configure the kernel
through “tpm.locality_on_suspend=1” boot parameter so that the locality is set before suspend/shutdown in order to diagnose whether or not the board is one of the buggy ones that require this workaround. Since this bug is related to the board/platform instead of the specific TPM chip, call dmi_check_system on the tpm_init function so that this setting is automatically enabled for boards specified in code (ASUS TUF GAMING B460M-PLUS already included) – automatic configuration only works in case CONFIG_DMI is set though, since dmi_check_system is a non-op when CONFIG_DMI is not set.

In case “tpm.locality_on_suspend=0” (the default) don't change any behavior thus preserving current functionality of any other board except ASUSTeK COMPUTER INC. TUF GAMING B460M-PLUS and possibly future boards as we successfully diagnose other boards with the same issue fixed by using “tpm.locality_on_suspend=1”.

Thank you for the instructions!

First I used gmail and even setting it to text only it destroyed formatting. Later I set up git to send the e-mail directly.

I read everything you asked again and implemented all suggestions, sending it right away.

Dear Adam,

Thank you very much for analyzing the problem and finding a fix. I have some small nits and questions. The current state is alright. Should you send another version, that you could address the nits.

Am 07.03.24 um 23:49 schrieb Adam Alves:

Out of curiosity, would reboot work?

I’d use `` from Markdown.

Could you please document the TPM for completeness?

Is the exception useful, if a user explicitly requests to disable the behavior? I was thinking for a case, where a newer system firmware has a fix (and the DMI check would need to be extended).

For completeness, I’d mention/paste the new log message.

Should this be backported to the stable series?

Dear Paul,

Thank you very much for your review, I will provide a new version with some of your suggestions.

Reboot works, but clearly in an error handling path by the firmware (the whole system is powered off for some seconds and then turned backed on automatically), this doesn't happen when I am rebooting from another OS. With this fix, reboot goes softly in Linux as well.

Done. Will be submitted with a new version.

Thanks! Will submit a new version with possibility to set module param to force enable, force disable and auto. Will also include cmdline documentation on parameter.

Will be submitted with a new version.

That would be great, please advise me if I need to do anything to allow that.

Thank you, will include this on the next version, submitting shortly - I am currently testing.

Best,
Adam Alves

Failing to do so would leave the system in a hanged state before sleep or power off (after “reboot: Power down” message). Such is the case for the ASUSTeK COMPUTER INC.

In case tpm.sleep_locality_preserve=0 force the workaround to be disabled.

In case tpm.sleep_locality_preserve=-1 (the default) automatically enable the workaround for specific boards (currently only ASUSTeK COMPUTER INC. TUF GAMING B460M-PLUS, others should be added when we diagnose this specific issue), if a compatible board is detected an info message will be logged with the following text: "Board XXX: TPM locality preserved before suspend/shutdown.".

---
v2->v3:
- Fixed quotes on commit text and included TPM chip used on test setup
- Allow forcing pre-fix behavior even for buggy boards
- Documented logged message for detected boards
- Changed parameter name to tpm_sleep_locality_preserve, since shutdown is also a sleep state
- Included kernel cmdline parameter documentation

Re-write the paragraph as

ASUSTeK TUF GAMING B460M-PLUS hangs on power down, after "reboot:
Power down" message

Please do not add discussion to the commit message it should only contain symptom and solution and rationale why the patch fixes the issue.

And please done add any open-ended arguments ("some ..."). We care only about identified bugs.

The lacking information here is the CPU model (/proc/cpuinfo), on which kernel version the bug was produced and what kind of TPM the system has (discrete chip or firmware TPM should be easy to check from BIOS).

Also, which firmwre version you have and have you tested with the most up to date firmware (BIOS)?

Before drawing any conclusions we need to know the environment better.

What is "the ACPI command"? Refer to concrete items instead of asking to guess what you is the ACPI command for you.

We don't speculate about the root cause here, only document it. Please move this paragraph before diffstat (see below)>

Please describe what the *kernel command-line" (for clarity sake) semantically means.

Also please remove anything about diangnosing. We care only about fixes.

This neither documents the default value. I'm also lost did setting this "1" or "0" fix the issue in your case?

So: firmware version and being up-to-date is important and also this needs to be reproduciable with the mainline Linux tree, not distro kernel or custom kernel.

<cover letter>

OK, I'll try to check what is done here but please re-read "describing your changes" before sending next version:

Hi Jarkko,

Thank you very much for kindly reviewing this proposal.

After one week without any issues with my PC hanging, it happened again. It seems that the fix I am proposing is not final (it only reduced the frequency since it always happened when I shutdown after couple hours of power up time and now it only happened after two weeks with a similar usage rate).

I will share with you the data you requested below.

CPU model: Intel(R) Core(TM) i7-10700F CPU @ 2.90GHz I am attaching data from /proc/cpuinfo

TPM: No info on mainboard documentation regarding TPM. BIOS is not clear whether or not it is discrete or firmware. Based on dmidecode (attached) I get the following:
TPM Device
Vendor ID: INTC
Specification Version: 2.0
Firmware Revision: 500.16
Description: INTEL
Characteristics:
Family configurable via platform software support
OEM-specific Information: 0x00000000
I also extracted TPM_CRB_INTF_ID_0 from the TPM: a13a808600084311 (Vendor ID 8086, Device ID a13a, Revision ID 00). The only match I found while browsing for this device ID is 100 Series/C230 Series Chipset Family MEI Controller #1, which is a PCI device, so it might not be related to the TPM.

The driver bound to the tpm0 device is tpm_crb. The disassembled TPM2 ACPI table is also attached in case it helps.

The bug was reproduced from upstream kernel version 6.8.0 (attached build .config that I used).

I have the most updated firmware provided by ASUS: TUF GAMING B460M-PLUS BIOS 1601

I enabled ACPI_DEBUG on my kernel to know where the it was actually hanging. The last function is actually the last function that should be called by the kernel for a successful shutdown:
hwsleep-0078 hw_legacy_sleep : Entering sleep state [S5]^M
hwregs-0460 hw_write_pm1_control : ----Entry^M hwvalid-0097 hw_validate_io_request: ----Entry^M hwvalid-0111 hw_validate_io_request: Address 0000000000001804 LastAddress 0000000000001805 Length 2 hwvalid-0128
hw_validate_io_request: ----Exit- AE_OK^M
hwregs-0360 hw_write : Wrote: 0000000000001C01 width 16
to 0000000000001804 (SystemIO)^M
hwregs-0473 hw_write_pm1_control : ----Exit- AE_OK^M hwregs-0460 hw_write_pm1_control : ----Entry^M hwvalid-0097 hw_validate_io_request: ----Entry^M hwvalid-0111 hw_validate_io_request: Address 0000000000001804 LastAddress 0000000000001805 Length 2 hwvalid-0128
hw_validate_io_request: ----Exit- AE_OK^M

It is writing both SLP_TYP + SLP_EN to ACPI PM1b_CNT registers (as expected by specification). I checked the flags and it is in line with the flags required by the system ACPI tables.

I understand from that that the system is hanging after ACPI firmware takes over. The same issue happens if I force a EFI shutdown.

Since the the BUG has appeared again even with the fix implemented, I am holding this patch for now until I find a solution that permanently fixes the issue. The next time I try to submit a patch that will comply with all your suggestions, thank you very much.

I would appreciate if you had any hint on how I could keep digging to find the issue that might be causing this bug. This is an issue that only happens when I shutdown from Linux and my TPM is activated in BIOS. That's why my guess is that this is what should be causing it. From Windows, shutdown is always flawless.

Best regards,
Adam

Hi Jarkko,

I have an update here. I would like you to check if it makes sense before I submit a patch.

The problem might be related to the chip itself which leaves the idle state whenever the locality is relinquished.

I probed the chip while operating and noted that the TPM_CRB_CTRL_STS_0.tpmIdle bit (located at regs_t->ctrl_sts on crb_priv structure in tpm_crb.c) is always cleared whenever the locality is relinquished.

The result is that this chip never becomes idle since after going idle the locality is relinquished (tpm_chip_stop function in tpm-chip.c).

I patched the 7.8.0 kernel for bypassing the tpm_relinquish_locality call and so far the PC is suspending and power off normally, TPM_CRB_CTRL_STS_0.tpmIdle remains set whenever the device is not used now.

I believe this is related to this specific chip, if the fix remains working for 2 weeks I will submit the patch. Please advise me if it makes sense.

Best regards,
Adam

Fixing a typo: I patched the 6.8.0 kernel.

There's no real discrete chip. It is a TPM living in the firmware, namely management engine.

So first thing to check would be to update the BIOS entirely.

This can be verified as tpm_crb does print "goIdle timed out" if it does not go to idle. Should be visible in klog.

BR, Jarkko

Thanks I'll definitely check these in detail.

Any possible bug fix (if we decide to fix anything) is tpm_crb.c including possible kernel command-line parameters or whatever. The current proposal affects all the possible pieces of TPM hardware so in all cases it is unacceptable.

Do you have dmesg/journactl transcript? Did you try to update the firmware?

BR, Jarkko

OK so I do have ASUS motherboard and my TPM2 ACPI table is almost the same match but:

BIOS Information
Vendor: American Megatrends Inc.
Version: 2212
Release Date: 12/13/2022
Address: 0xF0000
Runtime Size: 64 kB
ROM Size: 24 MB

Where as in you dmidecode.txt:

Handle 0x0000, DMI type 0, 26 bytes
BIOS Information

	Vendor: American Megatrends Inc.
	Version: 1601
	Release Date: 02/11/2022
	Address: 0xF0000
	Runtime Size: 64 kB
	ROM Size: 16 MB

So at least the BIOS version is older. Can you update BIOS and see if that could possibly fix the issue?

Make sure that it contains update for both BIOS and Management Engine.

BR, Jarkko

AND if you end up still proposing any fix please make sure that it only changes tpm_crb.c so that there is something to analyze. Sprinkled arbitrary changes are not something we can really not say much.

If you don't know exactly what you are fixing and why please try to keep the fix local to the issue. But yeah, BIOS update is really the first trial here.

BR, Jarkko
