Adding PCIe Hotplug Support for AMDKFD: the support of hot-plug of GPU
devices can open doors for many advanced applications in data center
in the next few years, such as for GPU resource
disaggregation. Current AMDKFD does not support hotplug out b/o the
following reasons:

1. During PCIe removal, decrement KFD lock which was incremented at
the beginning of hw fini; otherwise kfd_open later is going to
fail.
I assumed you read my comment last time, still you do same approach.
More in details bellow
Aha, I like your fix:) I was not familiar with drm APIs so just only half understood your comment last time.

BTW, I tried hot-plugging out a GPU when rocm application is still running.
From dmesg, application is still trying to access the removed kfd device, and are met with some errors.


Application us supposed to keep running, it holds the drm_device
reference as long as it has an open
FD to the device and final cleanup will come only after the app will die
thus releasing the FD and the last
drm_device reference.

Application would hang and not exiting in this case.


Actually I tried kill -7 $pid, and the process exists. The dmesg has some warning though.

So it means the process was stuck in some wait_event_killable (maybe here drm_sched_entity_flush) - you can try 'cat/proc/$process_pid/stack' maybe before
you kill it to see where it was stuck so we can go from there.



For graphic apps what i usually see is a crash because of sigsev when
the app tries to access
an unmapped MMIO region on the device. I haven't tested for compute
stack and so there might
be something I haven't covered. Hang could mean for example waiting on a
fence which is not being
signaled - please provide full dmesg from this case.


Do you have any good suggestions on how to fix it down the line? (HIP runtime/libhsakmt or driver)

This just probably means trying to update PTEs after the physical device
is gone - we usually avoid this by
first trying to do all HW shutdowns early before PCI remove completion
but when it's really tricky by
protecting HW access sections with drm_dev_enter/exit scope.

For this particular error it would be the best to flush
info->restore_userptr_work before the end of
amdgpu_pci_remove (rejecting new process creation and calling
cancel_delayed_work_sync(&process_info->restore_userptr_work) for all
running processes)
somewhere in amdgpu_pci_remove.

I tried something like *kfd_process_ref_release* which I think did what you described, but it did not work.


I don't see how kfd_process_ref_release is the same as I mentioned above, what i meant is calling the code above within kgd2kfd_suspend (where you tried to call kfd_kill_all_user_processes bellow)

Yes, you are right. It was not called by it.


Instead I tried to kill the process from the kernel, but the amdgpu could **only** be hot-plugged in back successfully only if there was no rocm kernel running when it was plugged out. If not, amdgpu_probe will just hang later. (Maybe because amdgpu was plugged out while running state, it leaves a bad HW state which causes probe to hang).


We usually do asic_reset during probe to reset all HW state (checlk if amdgpu_device_init->amdgpu_asic_reset is running when you  plug back).

OK



I don’t know if this is a viable solution worth pursuing, but I attached the diff anyway.

Another solution could be let compute stack user mode detect a topology change via generation_count change, and abort gracefully there.

From looking into kill_pid I see it only sends a signal but doesn't wait for completion, it would make sense to wait for completion here. In any case I would actually try to put here

I have made a version which does that with some atomic counters. Please read later in the diff.


hash_for_each_rcu(p_info)
    cancel_delayed_work_sync(&p_info->restore_userptr_work)

instead  at least that what i meant in the previous mail.

I actually tried that earlier, and it did not work. Application still keeps running, and you have to send a kill to the user process.

I have made the following version. It waits for processes to terminate synchronously after sending SIGBUS. After that it does the real work of amdgpu_pci_remove.
However, it hangs at amdgpu_device_ip_fini_early when it is trying to deinit ip_block 6 <sdma_v4_0> (https://gitlab.freedesktop.org/agd5f/linux/-/blob/amd-staging-drm-next/drivers/gpu/drm/amd/amdgpu/amdgpu_device.c#L2818<https://nam06.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgitlab.freedesktop.org%2Fagd5f%2Flinux%2F-%2Fblob%2Famd-staging-drm-next%2Fdrivers%2Fgpu%2Fdrm%2Famd%2Famdgpu%2Famdgpu_device.c%23L2818&data=05%7C01%7Cshuotaoxu%40microsoft.com%7C1ce273d333a04fde7dcf08da221de5f7%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C637859809165306474%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=W%2FvVPYbOl3sDNrOriqhJnAvudww%2B2ucBi3jwgwyje%2Bs%3D&reserved=0>). I assume that there are still some inflight dma, therefore fini of this ip block thus hangs?

The following is an excerpt of the dmesg: please excuse for putting my own pr_info, but I hope you get my point of where it hangs.

I just remembered that the idea to actively kill and wait for running user processes during unplug was rejected
as a bad idea in the first iteration of unplug work I did (don't remember why now, need to look) so this is a no go.

Maybe an application has kfd open, but was not accessing the dev. So kill it at unplug could kill the process unnecessarily.
However, the latest version I had with the sleep function got rid of the IP block fini hang.

Our policy is to let zombie processes (zombie in a sense that the underlying device is gone) live as long as they want
(as long as you able to terminate them - which you do, so that ok)
and the system should finish PCI remove gracefully and be able to hot plug back the device.  Hence, i suggest dropping
this direction of forcing all user processes to be killed, confirm you have graceful shutdown and remove of device
from PCI topology and then concentrate on why when you plug back it hangs.

So I basically revert back to the original solution which you suggested.

First confirm if ASIC reset happens on
next init.

This patch works great at planned plugout, where all the rocm processes are killed before plugout. And device can be added back without a problem.
However unplanned plugout when there is rocm processes are running just don’t work.


Still I am not clear if ASIC reset happens on plug back or no, can you trace this please ?


I tried add pr_info into asic_reset functions, but cannot trace any upon plug-back.


This could possibly explain the hang on plug back. Can you see why we don't get there ?


Is amdgpu supposed to asic_reset each time when it is probed? I right now it seems to probe ok (it did not hang). I will trace back further


Yep



Second please confirm if the timing you kill manually the user process has impact on whether you have a hang
on next plug back (if you kill before

Scenario 0: Kill before plug back

1. echo 1 > /sys/bus/pci/…/remove, would finish.
But the application won’t exit until there is a kill signal.


Why you think it must exit ?

Because rocm will need to release the drm descriptor to get amdgpu_amdkfd_device_fini_sw called, which would eventually call kgd2kfd_device_exit called. This would clean up kfd_topology at least. Otherwise I don’t see how it would be added back without messing up kfd topology to say the least.

However, those are all based my own observations. Please explain why it does not need exit if you believe so?


Note that when you add back a new device, pci device and drm device are created, I am not an expert on KFD code but i believe also a new KFD device is created independent of the old one and so the topology should see just 2 device instances (one old zombie and one real new).  I know at least this wasn't an issue for the graphic stack in exact same scenario and the libdrm tests i pointed to test exact this scenario.

Yes, regardless of the OOPS in ttm_bo_cleanup_refs, I plugged back the gpu, and I think it got probed all right, however the old kfd node is still there.
I can passed libdrm basic test suite on the plugged back. The bo test hangs out-of-box even without hotplug (see dmesg below).

I also tried to run tf benchmark to the newly plugged nodes (one of the node is dummy), but failed.
Can we have some confirmation from kfd team that they have considered a zombie kfd node?


Also note that even with running grpahic stack there is always a KFD device and KFD topology present but of course probably not the same as when u run a KFD facing process so there could be some issues there.

Also note that because of this patch https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=267d51d77fdae8708b94e1a24b8e5d961297edb7<https://nam06.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgit.kernel.org%2Fpub%2Fscm%2Flinux%2Fkernel%2Fgit%2Ftorvalds%2Flinux.git%2Fcommit%2F%3Fid%3D267d51d77fdae8708b94e1a24b8e5d961297edb7&data=05%7C01%7Cshuotaoxu%40microsoft.com%7C1ce273d333a04fde7dcf08da221de5f7%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C637859809165306474%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=oTS%2Brv6DOjcwSfKCHDgzrffsn3Qxl1hkfnexUqCRVaY%3D&reserved=0> all MMIO accesses from such zombie/orphan user processes will be remapped to zero page and so will not necessarily experience a segfault when device removal happnes but rather maybe some crash due to NULL data read from MMIO by the process and used in some manner.

It depends on where the application is when the device is plugged out.

For example, in one case, the application keeps saying out-of-memory, but won’t exit.
For one of the cases. The other case is that it would wait for a signal.

2. kill the the process. The application does several things and seems trigger drm_release in the kernel, which are met with kernel NULL pointer deference related to sysfs_remove. Then the whole fs just freeze.

This is a known regression, all SYSFS components must be removed before pci_remove code runs otherwise you get either warnings for single file removals or
OOPSEs for sysfs gorup removals like here. Please try to move amdgpu_ras_sysfs_remove from amdgpu_ras_late_fini to the end of amdgpu_ras_pre_fini (which happens before pci remove)


I fixed it in the newer patch, please see it below.



I first plugout the device, then kill the rocm user process. Then it has other OOPSES related to ttm_bo_cleanup_refs.

This looks like another regression - try seeing where is the NULL reference and then we can see how to avoid this.


Those are the line of code.

3.  echo 1 > /sys/bus/pci/rescan. This would just hang. I assume the sysfs is broken.

Based on 1 & 2, it seems that 1 won’t let the amdgpu exit gracefully, because 2 will do some cleanup maybe should have happened before 1.

or you kill after plug back does it makes a difference).

Scenario 2: Kill after plug back

If I perform rescan before kill, then the driver seemed probed fine. But kill will have the same issue which messed up the sysfs the same way as in Scenario 2.


Final Comments:

0. cancel_delayed_work_sync(&p_info->restore_userptr_work) would make the repletion of amdgpu_vm_bo_update failure go away, but it does not solve the issues in those scenarios.


Still - it's better to do it this way even for those failures to go awaya

Cancel_delayed_work is insufficient, you will need to make sure the work won’t be processed after plugout. Please see my patch


Saw, see my comment.



1. For planned hotplug, this patch should work as long as you follow some protocol, i.e. kill before plugout. Is this patch an acceptable one since it provides some added feature than before?


Let's try to fix more as I advised above.


2. For unplanned hotplug when there is rocm app running, the patch that kill all processes and wait for 5 sec would work consistently. But it seems that it is an unacceptable solution for official release. I can hold it for our own internal usage.  It seems that kill after removal would cause problems, and I don’t know if there is a quick fix by me because of my limited understanding of the amdgpu driver. Maybe AMD could have a quick fix; Or it is really a difficult one. This feature may or may not be a blocking issue in our GPU disaggregation research down the way. Please let us know for either cases, and we would like to learn and help as much as we could!


I am currently not sure why it helps. I will need to setup my own ROCm setup and retest hot plug to check this in more depth but currently i have higher priorities. Please try to confirm ASIC reset always takes place on plug back
and fix the sysfs OOPs as I advised above to clear up at least some of the issues. Also please describe to me exactly what you steps to reproduce this scenario so later I might be able to do it myself.

I can still try to help to fix the bug in my spare time. My setup is as follows


  1.  I have a server with 4 AMD MI100 GPUs. I think 1 GPU would also work.
  2.  I used the https://github.com/RadeonOpenCompute/ROCK-Kernel-Driver/tree/roc-5.0.x<https://nam06.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2FRadeonOpenCompute%2FROCK-Kernel-Driver%2Ftree%2Froc-5.0.x&data=05%7C01%7Cshuotaoxu%40microsoft.com%7C1ce273d333a04fde7dcf08da221de5f7%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C637859809165306474%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=BigmopnuPSHNpwYjKPOKvsdyFPHVcZRLPgzR3PuvXbU%3D&reserved=0> as the starting point, and apply Mukul’s patch and my patch.
  3.  Then I run a tensorflow benchmark from a docker.
     *   docker run -it --device=/dev/kfd --device=/dev/dri --group-add video rocm/tensorflow:rocm4.5.2-tf1.15-dev
     *   And run the following benchmark in the docker:  python benchmarks/scripts/tf_cnn_benchmarks/tf_cnn_benchmarks.py --num_gpus=4 --batch_size=32 --model=resnet50 --variable_update=parameter_server
        *   Might to need to adjust num_gpus parameter based on your setup
  4.  Remove a GPU at random time.
  5.  Do whatever is needed to before plugback and reverify the benchmark can still run.

Also, we have hotplug test suite in libdrm (graphic stack), so maybe u can install libdrm and run that test suite to see if it exposes more issues.

OK I could try it some time.


I tried suite 13, the hotplugout test, but it says it got killed? There are a some oops from dmesg during ttm_pool_free_page.

Probably better  to again use drm_dev_enter/exit guard pair instead of this flag.


I don’t know if I could use drm_dev_enter/exit efficiently because a process can have multiple drm_dev open. And I don’t know how I can recover/refer drm_dev(s) efficiently in the worker function in order to use drm_dev_enter/exit.


I think that within the KFD code each kfd device belongs or points to one specific drm_device so I don't think this is a problem.

Same as i mentioned above with drm.dev_eneter/exit

Same as I mentioned as the process can have many drm_dev open.

Final comments:

I suspect that the my linux kernel version might not have all the fixes you did for hotplug. Can you give me a pointer to the lowest version of linux kernel (5.14 from linux kernel repo? amd-drm-staging-next does not work for MI100 out-of-box), which would pass all libdrm tests including hotplug tests (some tests hang, some failed now) ?


That a problem, latest working baseline I tested and confirmed passing hotplug tests is this branch and commit https://gitlab.freedesktop.org/agd5f/linux/-/commit/86e12a53b73135806e101142e72f3f1c0e6fa8e6<https://nam06.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgitlab.freedesktop.org%2Fagd5f%2Flinux%2F-%2Fcommit%2F86e12a53b73135806e101142e72f3f1c0e6fa8e6&data=05%7C01%7Cshuotaoxu%40microsoft.com%7C1ce273d333a04fde7dcf08da221de5f7%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C637859809165356475%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=tsMzw%2BphQCOvNs9%2FFue1ApMO2RnrJvilW6Kld4rnsco%3D&reserved=0> which is amd-staging-drm-next. 5.14 was the branch we ups-reamed the hotplug code but it had a lot of regressions over time due to new changes (that why I added the hotplug test to try and catch them early). It would be best to run this branch on mi-100 so we have a clean baseline and only after confirming  this particular branch from this commits passes libdrm tests only then start adding the KFD specific addons. Another option if you can't work with MI-100 and this branch is to try a different ASIC that does work with this branch (if possible).

OK I tried both this commit and the HEAD of and-staging-drm-next on two GPUs( MI100 and Radeon VII) both did not pass hotplugout libdrm test. I might be able to gain access to MI200, but I suspect it would work.

I copied the complete dmesgs as follows. I highlighted the OOPSES for you.

Radeon VII:

Really appreciate your help!

Best,

2. Remove redudant p2p/io links in sysfs when device is hotplugged
out.

3. New kfd node_id is not properly assigned after a new device is
added after a gpu is hotplugged out in a system. libhsakmt will
find this anomaly, (i.e. node_from != <dev node id> in iolinks),
when taking a topology_snapshot, thus returns fault to the rocm
stack.

-- This patch fixes issue 1; another patch by Mukul fixes issues 2&3.
-- Tested on a 4-GPU MI100 gpu nodes with kernel 5.13.0-kfd; kernel
5.16.0-kfd is unstable out of box for MI100.
