ACPI Feilds dump before during and after the problem
Hi,
I'm trying to implement automatic user-space platform profile controls for my
ThinkPad and noticed that while under load, i.e. compiling the kernel, the
firmware (I think) will start sending `ibm/hotkey LEN0268:00 00000080 00006032`
events non-stop, which causes thinkpad_acpi to update the platform profile.
This happens once every second. However, the profile doe's not change. This
render any userspace tool useless, since we cannot react according to Fn +
[L|M|H] events.
While this is happening, the max frequency scaling will get stuck at a maximum
of around 2990MHz (78 C). The baseline for this model, from my measurements, is
3.400MHz (95 C). This seems to happen only if the GPU is used and DYTC is in
MMC mode.
I can reproduce this reliably by playing a full-screen YouTube video while
compiling the kernel.
Changing platform profile to low-power and then back to performance fixes this
for a while. I've also noticed that leaving the deceive sleeping for long
periods of time fixes this.
I've tried looking at the DYTC implementation but didn't find anything special
about going into low-power, I've tried to dump the the ACPI fields using
acpi_dbg, but haven't found anything useful yet.
I've attached the dumps (in the same file), which are:
- before, taken after reboot.
- during, taken while the firmware is sending 6032 events and frequency scaling
is stuck;
- after, taken after changing the platform profile to low-power and back to
performance (this was done using Fn + L then Fn + H)
Bellow, also, is the diff between during and after. But it does not show
anything useful to me.

Tested on:
- Kernel: 6.8.1

- UEFI: 0.1.30
I'm willing to help debug this in any way I can, though i'm out of ideas right
now. I'm also not sure if this is a firmware bug and wanted a second opinion
before sinking more time into this.

Thank you for the bug report. I'm adding Mark Pearson from Lenovo to the Cc.
Mark, can you took a look at this please ?

Thanks! (for my reference - L14 G3 AMD)
I've created internal ticket LO-2964 and we'll see if we can reproduce and get
insight from the FW team as to what is happening.
If you have some of the ACPI events recorded (I assume you're running
acpi_listen?) that might be useful - just so we can show the FW team what
events are being sent. Hopefully we can reproduce the issue in the lab though.

Sorry for the delay. There is not much to it, just a spam of 6032 events.
This is what i did, from fresh boot:
1) compile the kernel, platform profile is set to performance;
2) while compiling, open firefox and play a youtube video (not sure yet if it
makes a difference but i make the video full screen);
3) wait, around 7 minutes later something will start sending 6032 events.
```

```
The first event is me pressing Fn + H. I'm reading the events using netlink so
i can add timestamps, i did double check and acpi_listen shows the same thing.

Hey Mark, I was testing today and noticed that it happens when GPU temps reach
~70C.

--- Comment #9 from Lucas Mülling (lmulling@proton.me) ---
Under 6.9, from initial testing, it seems that the frequency scaling issue was
fixed, possible by a change in amd-pstate? my guess.
I've also tested this:
https://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git/patch/?id=c7e29dcef9ca4a93eed092e6739277a92a64fbe3.
Seems to be the same as 6.9, tho a degree more conservative.
6032 event spam still happens.

Hi - sorry for the slow reply, crazy busy time of year.
We've not been able to reproduce the issue on our system - can you confirm
which BIOS and EC you are running please? I think you have BIOS 1.30 but need
to confirm the EC version too - it is shown if you enter the BIOS setup screen
(F1 during boot) or from 'fwupdmgr get-devices'
Thanks
Mark

Hi,
No worries, I might have (un)lucky hardware.
The EC version is 0.1.25, BIOS is 0.1.30.

Thanks - that matches what we tested with. I've asked the FW team for more
guidance on if this is a HW issue - it feels like it to me :(

Thanks, I'm out of ideas, so anything is appreciated (even opening this thing
and probing it). I've tried the kernel ACPI debugging stuff, but it was just
noise to me.
One thing i forgot to mention, the machine does make a weird coil-wine sound
under certain loads, the kernel instruction decoding sanity test seems to
trigger it 100%. Happens both on AC and battery. I Will try and get a video of
it tomorrow.

--- Comment #14 from Mark Pearson (mpearson-lenovo@squebb.ca) ---
I have been remiss on adding updates to this bug - sorry!
We found a system able to reproduce the problem, and the FW team have
investigated and have a fix. It's related to hitting a thermal threshold and
then the EC FW incorrectly generating events.
The fix will be in EC version R1YHT44W - expected to release 19th August (but
please allow for some variability - it's under testing and dates can change
etc). I'll be monitoring for this to be released to LVFS.

Hi Mark, I've tried searching LVFS for that version but didn't found it,
fwupdmgr also shows no updates for my machine, was the update on 19th of August
or September?

Hi Mark,
Just to update this, I've updated the EC to version R1YHT44W. Been testing for
a few days now and could not reproduce de problem anymore, there's still the
weird frequency scaling thing but this is probably unrelated to any firmware.
Thanks again!
