Hi,

The file "f29bb3d9-bd66-5441-afb88acc2b2b60d6.bin" is missing from the "/lib/firmware/amdtee" folder, which is causing the issue. This is because there have been some last-minute modifications to the TA firmware, and as a result, the firmware has not yet been updated. I will inform you once the updated TA firmware is available, so you can provide your feedback at that time.

Thanks,
Shyam

Subject: [REGRESSION][BISECTED] Firmware load error for TEE on Framework Desktop

Hello everyone,

I have recently noticed an issue on the Framework Desktop where the following error pops up in dmesg after upgrading to any version beyond
v6.14:

[   12.136102] tee tee0: Direct firmware load for /amdtee/f29bb3d9-bd66-5441-afb88acc2b2b60d6.bin failed with error -2
[   12.141252] input: HD-Audio Generic HDMI/DP,pcm=8 as /devices/pci0000:00/0000:00:08.1/0000:c1:00.1/sound/card0/input8
[   12.141601] failed to load firmware /amdtee/f29bb3d9-bd66-5441-afb88acc2b2b60d6.bin
[   12.141843] input: HD-Audio Generic HDMI/DP,pcm=9 as /devices/pci0000:00/0000:00:08.1/0000:c1:00.1/sound/card0/input9
[   12.142005] failed to copy TA binary
[   12.185200] Failed to open TEE session err:0x0, rc:-12
[   12.185202] amd-pmf AMDI0105:00: Failed to open TA session (-12)

I have subsequently bisected the issue within the mainline kernel tree to the following commit:

    376a8c2a1443 ("platform/x86/amd/pmf: Update PMF Driver for Compatibility with new PMF-TA")

The error is still present in the latest mainline release 6.14 and sadly testing a revert is not trivially possible due to conflicts.

I also noticed that there is a commit with a fixes tag for the one we have bisected to, but it's included in the same release and therefore does not seem to fix the issue at hand:

    5b1122fc4995 ("platform/x86/amd/pmf: fix cleanup in amd_pmf_init_smart_pc()")

I have attached a dmesg output from a good boot and one from the 6.14 where the failure occurs. I'm happy to test any debug patches or provide more information if needed.

Greeting,
Chris
