Dear Linux folks,
It turns out that stricter checks in the ACPI subsystem, introduced in
commit 57707a9a77 (ACPICA: Resources: Not a valid resource if buffer
length too long) [1], cause the TPM module not to be loaded anymore on
the Lenovo X60 with coreboot [2].

```
I suggest, that just a warning is printed in this case, or that an
option is added to enable some kind of “strict mode” or a quirk table.
Please find the decompiled DSDT attached. The code to generate the ASL
coreboot code is available [3].
Please tell me, what information you need.
Kind regards,
Paul

Is it correct, that this is added in/for 4.11, so just recently? Testing
with Linux 4.10.8, everything is detected just fine.

If nothing comes to mind with the new information above, then I could do
that. But I don’t know, if I’ll have time in the next two weeks for
that.

No, it is quite a bit older.. And it should only go for TPM2, which I
don't think you have??
Maybe Jarkko has a guess, but sure sounds like something is recently
broken in 4.11

Fair point.. Jarkko - could you forward that patch to -stable?

There could be more relavent kernel messages than this, try
grep -i tpm
?

We added direct ACPI binding to the driver in addition to PNP, so if
you have an ACPI table it goes down that path and does some additional
validation of what is in the TPM. The BIOS must provide a
acpi_dev_resource_memory and a ACPI_SIG_TPM2 for the ACPI entry at a
minimum.
There are FW_BUG prints if those fail, so check your dmesg closely?
http://lxr.free-electrons.com/source/drivers/char/tpm/tpm_tis.c#L250
If not, can you annotate in some printk's into tpm_tis_acpi_init and
recompile/re-test?

GNUtoo got the messages below. Unfortunately, I don’t know, what Linux
Kernel that is.
```
tpm_tis 00:07: 1.2 TPM (device-id 0x3202, rev-id 5)
tpm tpm0: A TPM error (38) occurred attempting to determine the timeouts
tpm tpm0: Issuing TPM_STARTUP

Could you please help me with that? Can I enable certain options to get
more debugging information?

How can I increase the retry count?

Sorry, I don’t know. Leaving that out, gives the same messages though.
```
tpm tpm0: Unable to read burstcount
tpm tpm0: tpm_transmit: tpm_send: error -16
tpm_tis tpm_tis: Could not get TPM timeouts and durations
```

Hi,
Thank you for bisecting the issue. It would have been hard to achieve this
without the hardware. Do you want to create a patch for ACPICA?

Unfortunately I can't help here as I am just a normal TPM user who
happened to hit and fix that timeouts regression, but maybe others
on ML will know something more about it.

This looks like a regression I had on ThinkPad X61S.
You can try with a patch from the following commit
which fixed it for me:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=1d70fe9d9c3a4c627f9757cbba5d628687b121c1
It is included in mainline kernel 4.10.2.

How did this work on any kernels if there was no PNP or ACPI entry?
FWIW, I wonder if coreboot is missing the code for wait_startup
in drivers/char/tpm/tpm_tis_core.c. If you don't do that step then
the DID/VID might not read properly.

Unless it is an actual broken intel TPM you should never use
itpm=1. Juding by the log messages, it certainly is not.
Intel mode breaks the driver and removes certain error detection, eg
it may erronously succeed.
It is more likely that the failure to read PCRs reflects reality and
itpm=1 just supresses that error detection.
The TPM may need to be setup (eg cleared, EK generated, p/vflags setup
etc, etc) before it will support PCRs.
Usually the BIOS would do these steps when the TPM is first enabled,
you probably need to do them in userspace instead.
WARNING: Failure to provision the TPM properly before first use
could leave it in 'factory test' mode, which basically means it
doesn't work properly at all.

Don't do this unless it is actually that TPM.

That old kernel did not check error codes when reading burst count,
the new one does. It is quite possible the older kernel is failing to
read burst count and subtly malfunctioning.
It would be helpful if you could prove/disprove this statement by
adding some debugging to 3.16.
As to why the burst count cannot be read.. I don't know, check if
increasing the retries helps, it could be this particular TPM is out
of spec for the cold startup process.
> Remove module and run `sudo modprobe tpm_tis itpm=1 force=1`.
Is this really an 'itpm'? It doesn't look like it..

Indeed, that improves the situation. I still need to pass `force=1` to
the module to get `/dev/tpm0`. No idea, why it’s not in included in
Linux 4.9 yet.

I am working on it[1]. This commit has not been merged and is a work in
progress. It is however available in coreboot's gerrit.
So far with it and a recent kernel and the patch mentioned above:
- The linux driver finds the TPM automatically and doesn't require
force=1
- The driver however still require itpm=1 to fully work: without it the
tpm is found, but I wasn't able to read the PCRs.
Since I use a rolling release distribution, the kenrel version I use
tend to change quite fast, I can re-test if needed.
I need to improve the following in my patch:
- The IDs readings obviously need to be fixed.
- I want to make it work without itpm=1 if possible. I'll test with
INTC0102 as it is in the driver in the is_itpm function, and it was
also suggested to me by someone on IRC.
I also still need to investigate more why the itpm workaround is needed.
Does the TPM shipped in such laptops respect the specifications?
Is the wiring bad?

Dear Linux folks,
Currently, TPM support is added to the coreboot project for the Lenovo
X60 [1].
Unfortunately, there seems to have been a regression between Linux 3.16
and 4.8 and 4.9, so that the Linux kernel doesn’t create the TPM device.
```
$ more /proc/version Linux version 3.16.0-4-686-pae
(debian-kernel@lists.debian.org) (gcc version 4.8.4 (Debian 4.8.4-1) )
#1 SMP Debian 3.16.39-1+deb8u2 (2017-03-07)
$ journalctl -k -o cat | grep -i tpm
tpm_tis 00:08: 1.2 TPM (device-id 0x3202, rev-id 5)
tpm_tis 00:08: Issuing TPM_STARTUP
```
The device `/dev/tpm0` is present.
Here are the results with Linux 4.8.15.
```
kernel: [ 0.000000] Linux version 4.8.0-0.bpo.2-686-pae
(debian-kernel@lists.debian.org) (gcc version 4.9.2 (Debian 4.9.2-10) )
#1 SMP Debian 4.8.15-2~bpo8+2 (2017-01-17)
[…]

kernel: [ 11.302598] tpm_tis 00:08: Could not get TPM timeouts and
durations
```
Remove module and run `sudo modprobe tpm_tis itpm=1 force=1`.
```

```
And here with Linux 4.9.13.
```
kernel: [ 7.813547] tpm_tis 00:08: 1.2 TPM (device-id 0x3202, rev-id 5)
kernel: [ 7.891026] tpm tpm0: Issuing TPM_STARTUP
kernel: [ 8.042783] tpm tpm0: Unable to read burstcount

kernel: [ 8.042900] tpm_tis 00:08: Could not get TPM timeouts and duration
```
If I am not mistaken, the error code 16 is for the macro `EBUSY`.
It’d be great, if the TPM would also be created in the newer Linux
Kernel versions, so that Debian users can upgrade to the upcoming stable
release, which ships Linux 4.9.
Unfortunately, I won’t be able to bisect the commit introducing the
regression. Could you please tell me how to debug, why the burstcount
cannot be read.
Kind regards,
Paul
