[Issue]: enableing runtime pm causes failure to resume smu on mi100

[IMbackK]

Problem Description

Booting with runtime pm enabled causes the devices to fail to apear due to a failure to resume smu on mi100 devices, dmesg:

Hi @IMbackK. Internal ticket has been created to investigate this issue. Thanks!

[sohaibnd]

Hi @IMbackK, can you provide the full kernel log? And check if this issue present with amdgpu.runpm=0

[IMbackK]

the issue is not present with amdgpu.runpm=0, as is logical since the device is not suspended in this state and the error occurs on resume, i will provide a full log later as currently the machine is in use. Is there anything else i can gather for you at the same time?

[sohaibnd]

@IMbackK Thanks, some other questions to help repro this issue:

• What is triggering the resume? Are you running some workload?
• Which kernel version are you using (use uname -a command to check)?

Can you also run rocminfo with some environment variables to get more info: AMD_LOG_LEVEL=5 HSAKMT_DEBUG_LEVEL=7 rocminfo

[IMbackK]

What is triggering the resume? Are you running some workload?

The mi100 have entered a failed state before the machine is sufficently booted to be interactive, runtime suspend/resume happens fairly often, i understand this is normal. In the case of this machine there is a daemon that monitors hw sensors of the devices, presumably it causes the wakeup.

Which kernel version are you using (use uname -a command to check)?

I tried 6.6.75 with amdgpu-dkms (ie amdgpu from this repo) running and 6.13.1 with upstream amdgpu.

Can you also run rocminfo with some environment variables to get more info: AMD_LOG_LEVEL=5 HSAKMT_DEBUG_LEVEL=7 rocminfo

unfortionatly this dosent result in any additional prints:

% AMD_LOG_LEVEL=5 HSAKMT_DEBUG_LEVEL=7 rocminfo

Why are you using upstream kernels builds (from https://wiki.ubuntu.com/Kernel/MainlineBuilds I'm guessing) instead of the ones provided by Ubuntu (they aren't officially supported by ROCm either)? Did you try the default 6.8.0 kernel with Ubuntu 24.04 and amdgpu-dkms from https://repo.radeon.com included in the ROCm install docs?

[IMbackK]

I am self building kernels from kernel.org, i do this as i also do kernel development in other modules.

I can try 6.8 too but i do have the expectation that the upstream amdgpu works, maybe not for rocm where the ioctls the downstream kernel in this repo provides are used, but at the very least there should be no crash just from booting.

I gues since the issue occurs in both the kernel provided in this repo and in latest upstream stable i could also report this to the mailing list.

[sohaibnd]

Oh I see. Yes, do try the default 6.8.0 kernel from Ubuntu with both upstream amdgpu and the dkms module on https://repo.radeon.com.

I gues since the issue occurs in both the kernel provided in this repo and in latest upstream stable i could also report this to the mailing list.

Yeah that's a good idea.

[sohaibnd]

@IMbackK I tried reproducing with a 7900xtx and an upstream kernel 6.12 + upstream amdgpu on Ubuntu 24.04 but was unable to. Do you have any other info (HW/SW) about your system config that might be relevant? Did you build the kernel with any specific parameters or used any kernel boot parameters?

[IMbackK]

It for sure only happens on mi100 specifically, i also have a 6800xt in the same system that runtime suspends fine.
Besides amdgpu.runpm=1 i also have iommu=pt which may be relevant.

My kconfig only differs from the ubuntu default in that i enabled CONFIG_DMABUF_MOVE_NOTIFY=y and CONFIG_HSA_AMD_P2P=y both of which i have around to allow testing ROCR's dmabuf mode

[bjj]

This also happens on my Mi100 on Ubuntu 24.04 + standard ROCm install instructions. It is also fixed by amdgpu.runpm=0 This is on an MSI Z370M motherboard + i7-8700K.

I might be in a better place to try experiments than the submitter, since my card is not in production.

[LunNova]

I'm able to reproduce this issue with a system with multiple MI100s.

Running kernel and amdgpu built from the rocm-6.3.3 tag of this repository and amdgpu.runpm=1 results in this error when the card tries to resume:

[ 1075.338832] amdgpu 0000:c8:00.0: amdgpu: reserve 0x400000 from 0x87fe800000 for PSP TMR

This issue is MI100 specific. Any cause of resume triggers it, including a simple cat /sys/class/drm/card6/device/gpu_busy_percent. Adding env vars for logging in AMD userspace utilities is of no benefit.

[IMbackK]

@sohaibnd looks like this is pretty well established now, with regards to in what situation the crash occurs. Have you been able to reproduce this problem locally?

[darren-amd]

Hi @IMbackK,

I had a chat with the kernel team who confirmed that runtime PM is not supported on the MI100. Thanks for reporting the issue!
