All of the above do not work even though the driver is installed correctly. The above error prevents radeonsi from loading.

The good news is when I installed Both 23.04 and 23.10 they had 1 working firmware each they are:

Hope this helps get a working firmware out. I'd love to try rocm.

I extracted the firmware package from Lunar and compared the files to the one currently installed and noticed that amdgpu/gc_11_0_0_mes_2.bin is not present in the Lunar package.
Perhaps that is what is causing the issue?

[Mario Limonciello (superm1)]

Can you please share your kernel log from jammy when the failure has occurred?

We did test XTX working, suspect a separate issue.

[Lawrence A Fossi (darkfoss)]

Your comments lead me do some digging and it tuns out I had somehow broken the secure boot chain. After changing the 2 bios ccp settings from auto to enabled the psp loads correctly. I downgraded the firmware with muon then Discover notified me of an upgrade I had made sure that it was set to update on reboot. Everything appears to have installed in the correct manner, I now have fully working secure display.

There are 2 remaining issues 1 new 1 old.
The new issue occurred last night after installing the new kernel upgrade:Linux Tardis-2 6.2.0-36-generic #37~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Mon Oct 9 15:34:04 UTC 2 x86_64 x86_64 x86_64 GNU/Linux
I can actually see it during the boot up right after the Ubuntu slash screen and before the screen to unlock the drive encryption:

10/31/23 11:47 AM amd_gpio AMDI0030 0: Invalid config param 0014

I'm attaching the kernel log error occurs at the top right under init.

[Lawrence A Fossi (darkfoss)]

Second issue is resuming from sleep 1 error on shutdown different error on resume. I'm attaching the kernel log after resuming.

Sorry for the long delay from my initial post but I wanted to make sure I was providing clean information from a solid installation.

[Mario Limonciello (superm1)]

> amd_gpio AMDI0030 0: Invalid config param 0014

This is fixed by this patch:
https://github.com/torvalds/linux/commit/87b549efcb0f7934b0916d2a00607a878b6f1e0f

Canonical needs to backport that to applicable kernels.

> 10/31/23 12:11 PM WARNING CPU: 2 PID: 3763 at drivers/gpu/drm/amd/amdgpu/../display/dc/dcn32/dcn32_hwseq.c:1197 dcn32_calculate_dccg_k1_k2_values+0xec/0x120 [amdgpu]

I believe that likely Canonical is missing stable backports related to VRR.
You can cross reference a newer mainline kernel to confirm this.

[Lawrence A Fossi (darkfoss)]

I can confirm everything I'm seeing is fixed in mainline/v6.5.6 6.7.7 could not be tested due to a bad signature error.

The lone exception was amd_gpio AMDI0030 0: Invalid config param 0014. That is fixed in mainline/6.6.rc5
I did not test the earlier 6.6rc candidates.

[Lawrence A Fossi (darkfoss)]

The error going into sleep as well as the error coming out of sleep are now gone with the latest linux-hwe-6.2 update.Thank you.

I'm seeing this error now once going into sleep and once coming out no spam in the log. Other than an longer than normal delayed blanking of the screen no apparent issues with it. IE not seeing any of the issues reported in the bug report below.

11/28/23 10:35 PM kernel [drm:dcn20_wait_for_blank_complete [amdgpu]] *ERROR* DC: failed to blank crtc!

I found this bug report so it's already fixed in the future can upload the latest kernel log if needed.
