[PATCH v10 0/8] Add support for EU stall sampling

[PATCH v10 0/8] Add support for EU stall sampling

[Harish Chegondi]

The following patch series add support for EU stall sampling,
a new hardware feature first added in PVC and is being supported
in XE2 and later architecture GPUs. This feature would enable
capturing of EU stall data which include the IP address of the
instruction stalled and various stall reason counts.

Support for this feature is being added into Mesa:
https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/30142

New IGT tests for EU stall sampling are being added:
https://patchwork.freedesktop.org/series/143030/

This patch series has undergone basic testing with the new IGT tests.

Issues that need investigation:
1. Blocked reads with small user buffers may be blocked even with EU
stall data in the kernel buffer as a previous read has set pollin to
false even when kernel buffer has data that could be read but the user
buffer is too small to read all the data.

Thank You.

v10 a. Fixed error rewinding code
    b. Used cancel_delayed_work_sync() instead of flush_delayed_work()
    c. Replaced per xecore lock with a lock for all the xecore buffers
    d. Remove function description for static functions.
    e. Use extension number while parsing chain of extensions.
    f. Moved code around as per review feedback
v9: a. Split the big patch in v8 into two patches
    b. Moved all drop data handling code into one patch
    c. Several other code improvements as mentioned in the patches
v8: a. Used div_u64() instead of / to fix 32-bit build issue.
    b. Changed copyright year in new files to 2025.
    c. Renamed struct drm_xe_eu_stall_data_pvc to struct xe_eu_stall_data_pvc
    d. Renamed struct drm_xe_eu_stall_data_xe2 to struct xe_eu_stall_data_xe2

v7: a. Renamed input property DRM_XE_EU_STALL_PROP_EVENT_REPORT_COUNT
       to DRM_XE_EU_STALL_PROP_WAIT_NUM_REPORTS to be consistent with
       OA. Renamed the corresponding internal variables.
    b. Fixed some commit messages based on review feedback.
    c. Changed sampling_rates from a pointer to flexible array.

v6: a. Changed the uAPI input to accept sampling rate in GPU cycles
       instead of sampling rate multiplier.
    b. Fix buffer wrap around over write bug (Matt Olson).
    c. Include EU stall sampling rates information and per XeCore buffer size in the query information.

v5: Addressed review feedback from v4 including
    a. Removed DRM_XE_EU_STALL_PROP_POLL_PERIOD from the uAPI (Ashutosh)
    b. Separated the patches for Xe_HPC and Xe2 (Matt R)
    c. Moved read() returning -EIO into a separate patch
    d. Removed spinlocks around set_bit() and clear_bit() (Matt R)
    e. Renamed several variables, structures and enums (Ashutosh and
Matt R)
    f. Addressed other review feedback.

    b. Added a new DRM_XE_OBSERVATION_IOCTL_INFO to query EU stall data record info
    c. Added struct drm_xe_eu_stall_data_pvc and struct drm_xe_eu_stall_data_xe2
       to xe_drm.h. These declarations would help user space to parse the
       EU stall data
    d. Addressed other review comments from v2

[PATCH v10 1/8] drm/xe/topology: Add a function to find the index of the last enabled DSS in a mask

[Harish Chegondi]

Last enabled DSS in a DSS mask can help estimate the maximum DSSes enabled
in the DSS mask, as the enabled DSSes can be discontiguous.

[PATCH v10 2/8] drm/xe/uapi: Introduce API for EU stall sampling

[Harish Chegondi]

A new hardware feature first introduced in PVC gives capability to
periodically sample EU stall state and record counts for different stall
reasons, on a per IP basis, aggregate across all EUs in a subslice and
record the samples in a buffer in each subslice. Eventually, the aggregated
data is written out to a buffer in the memory. This feature is also
supported in XE2 and later architecture GPUs.

Use an existing IOCTL - DRM_IOCTL_XE_OBSERVATION as the interface into the
driver from the user space to do initial setup and obtain a file descriptor
for the EU stall data stream.  Input parameter to the IOCTL is a struct
drm_xe_observation_param in which observation_type should be set to
DRM_XE_OBSERVATION_TYPE_EU_STALL, observation_op should be
DRM_XE_OBSERVATION_OP_STREAM_OPEN and param should point to a chain of
drm_xe_ext_set_property structures in which each structure has a pair of
property and value. The EU stall sampling input properties are defined in
drm_xe_eu_stall_property_id enum.

With the file descriptor obtained from DRM_IOCTL_XE_OBSERVATION, user space
can enable and disable EU stall sampling with the IOCTLs:
DRM_XE_OBSERVATION_IOCTL_ENABLE and DRM_XE_OBSERVATION_IOCTL_DISABLE.
User space can also call poll() to check for availability of data in the
buffer. The data can be read with read(). Finally, the file descriptor
can be closed with close().

v10: Use extension number while parsing chain of extensions.
     Remove function description for static functions.
     Move code around as per review feedback.
v9: Changed some u32 to unsigned int.
    Moved some code around as per review feedback from v8.
v8: Used div_u64 instead of / to fix 32-bit build issue.
    Changed copyright year in xe_eu_stall.c/h to 2025.
v7: Renamed input property DRM_XE_EU_STALL_PROP_EVENT_REPORT_COUNT
    to DRM_XE_EU_STALL_PROP_WAIT_NUM_REPORTS to be consistent with
    OA. Renamed the corresponding internal variables.
    Fixed some commit messages based on review feedback.
v6: Change the input sampling rate to GPU cycles instead of
    GPU cycles multiplier.

v9: Moved structure definitions from xe_eu_stall.h to xe_eu_stall.c
    Moved read and poll implementations to the next patch
    Used xe_bo_create_pin_map_at_aligned instead of xe_bo_create_pin_map
    Changed lock names as per review feedback
    Moved drop data handling into a subsequent patch
    Moved code around as per review feedback
v8: Updated copyright year in xe_eu_stall_regs.h to 2025.
    Renamed struct drm_xe_eu_stall_data_pvc to struct xe_eu_stall_data_pvc
    since it is a local structure.
v6: Fix buffer wrap around over write bug (Matt Olson)

[PATCH v10 4/8] drm/xe/eustall: Add support to read() and poll() EU stall data

[Harish Chegondi]

Implement the EU stall sampling APIs to read() and poll() EU stall data.
A work function periodically polls the EU stall data buffer write pointer
registers to look for any new data and caches the write pointer. The read
function compares the cached read and write pointers and copies any new
data to the user space.

v10: Used cancel_delayed_work_sync() instead of flush_delayed_work()
     Replaced per xecore lock with a lock for all the xecore buffers
     Code movement and optimizations as per review feedback
v9:  New patch split from the previous patch.
     Used *_delayed_work functions instead of hrtimer
     Addressed the review feedback in read and poll functions

[PATCH v10 5/8] drm/xe/eustall: Add support to handle dropped EU stall data

[Harish Chegondi]

If the user space doesn't read the EU stall data fast enough,
it is possible that the EU stall data buffer can get filled,
and if the hardware wants to write more data, it simply drops
data due to unavailable buffer space. In that case, hardware
sets a bit in a register. If the driver detects data drop,
the driver read() returns -EIO error to let the user space
know that HW has dropped data. The -EIO error is returned
even if there is EU stall data in the buffer. A subsequent
read by the user space returns the remaining EU stall data.

v10: Reverted the changes back to v8:
     Clear the drop bits only after reading the data.
v9:  Move all data drop handling code to this patch
     Clear all drop data bits before returning -EIO.

[PATCH v10 6/8] drm/xe/eustall: Add EU stall sampling support for Xe2

[Harish Chegondi]

Add EU stall sampling support for Xe2 architecture GPUs - LNL and BMG.
EU stall data format for LNL and BMG is different from that of PVC.

v10: Update comments as per review feedback

v9: Use GRAPHICS_VER() check instead of platform

v8: Renamed struct drm_xe_eu_stall_data_xe2 to struct xe_eu_stall_data_xe2
    since it is a local structure.

[PATCH v10 7/8] drm/xe/uapi: Add a device query to get EU stall sampling information

[Harish Chegondi]

User space can get the EU stall data record size, EU stall capabilities,
EU stall sampling rates, and per XeCore buffer size with query IOCTL
DRM_IOCTL_XE_DEVICE_QUERY with .query set to DRM_XE_DEVICE_QUERY_EU_STALL.
A struct drm_xe_query_eu_stall will be returned to the user space along
with an array of supported sampling rates sorted in the fastest sampling
rate first order. sampling_rates in struct drm_xe_query_eu_stall will
point to the array of sampling rates.

Any capabilities in EU stall sampling as of this patch are considered
as base capabilities. New capability bits will be added for any new
functionality added later.

v10: Change comments and variable names as per feedback
v9: Move reserved fields above num_sampling_rates in
    struct drm_xe_query_eu_stall.
v7: Change sampling_rates from a pointer to flexible array.
v6: Include EU stall sampling rates information and
    per XeCore buffer size in the query information.

How about moving this stream->xecore_buf allocation stuff into
xe_eu_stall_data_buf_alloc? Just move it before stream->bo allocation in
xe_eu_stall_data_buf_alloc.

Because in xe_eu_stall_data_buf_destroy() we are freeing both stream->bo
and stream->xecore_buf. So if we move this stream->xecore_buf allocation
into xe_eu_stall_data_buf_alloc, xe_eu_stall_data_buf_alloc and
xe_eu_stall_data_buf_destroy will be completely symmetric.

And by "data_buf" we can understand stream->bo and stream->xecore_buf taken
together. There are other ways of doing this too but I think this is the
simplest change.

After addressing the above comment above, the rest lgtm, so this patch is
also:

Why do we need this new lock? I thought we would just be able to use
gt->eu_stall->stream_lock? stream_lock is already taken for read(), so we
just need to take it for eu_stall_data_buf_poll()?

OK, won't block on this, but error unwinding is cleaner with label's and
goto's.

Also, if stream->buf_lock is needed, mutex_destroy is also needed for error
unwinding and also during stream close.

Keep it if we need it, but do we need both the read/write ptr's and
offset's? Since offset's are the same as ptr's, but without the ms bit.

I think I am ok with this patch as is. Unless we agree to drop data in the
driver (which I had proposed but you had rejected), I don't think we can do
a lot more without really complicating things. So I don't want to go there
yet.

But lets first go through the coments on PATCH v10 4/8. Once we resolve the
locking issue raised there, I will review this patch again and hopefully
R-b it.

See if you need to send a new revision of the series.

Thanks.

Related to the above would potentially be better locking for stream->pollin.

Not sure why we don't see the EU stall IGT's running in Xe.CI.Full.

I started off with using the gt->eu_stall->stream_lock. But I have seen
warnings in the dmesg log while testing indicating possible circular
locking dependency leading to a deadlock. Maybe I can spend more time
later to investigate further and eliminate the possible circular locking
dependency. But for now, I decided to use a new lock to eliminate the
per subslice lock. Here is the dmesg log that I saved from my testing to
investigate later.

Okay. But, before we do a free(stream), does it really matter to call
mutex_destroy on stream->buf_lock ?

True offsets are just pointers without the overflow bit. Maybe I can
remove the offsets, but add old read pointer (since read pointer changes
during read).

Could you try out this change in your patch (also just use
gt->eu_stall->stream_lock, not stream->buf_lock) and see if it resolves
this issue:

	@@ -573,7 +573,6 @@ static void xe_eu_stall_stream_free(struct xe_eu_stall_data_stream *stream)

	        xe_bo_unpin_map_no_vm(stream->bo);
	        kfree(stream->xecore_buf);
	 }
	@@ -829,6 +828,8 @@ static int xe_eu_stall_stream_close(struct inode *inode, struct file *file)
	        xe_eu_stall_stream_free(stream);

	+       destroy_workqueue(stream->buf_poll_wq);
	+
	        return 0;
	 }

Basically move destroy_workqueue outside gt->eu_stall->stream_lock.

I will look more into this. But from the above trace it looks like the
issue of lock order between two locks in different code paths. The two
locks are stream_lock and something let's call wq_lock (associated with the
workqueue or the work item).

So this is what we see about the order of these two locks in these
instances in the code (assuming we are only using stream_lock):

1. eu_stall_data_buf_poll_work_fn: wq_lock is taken first followed by
   stream_lock inside eu_stall_data_buf_poll.

2. xe_eu_stall_disable_locked: stream_lock is taken first followed by
   wq_lock when we do cancel_delayed_work_sync (if at all)

3. xe_eu_stall_stream_close: stream_lock is taken first followed by wq_lock
   when we do destroy_workqueue.

So looks like lockdep is complaining about the lock order reversal between
1. and 3. above. I am not sure if the order reversal between 1. and 2. is a
problem or not (if lockdep complains about this or not). If it is, we could
try moving cancel_delayed_work_sync also outside stream_lock. But we
haven't seen a trace for the second case yet.

So anyway, the first thing to try is the patch above and see if it fixes
this issue.

Another idea would be to move buf_poll_wq into gt->eu_stall (rather than
the stream), so it does not have to be destroyed when the stream fd is
closed.

Yes, we'd need mutex_destroy if we introduce stream->buf_lock. First let's
try the approach above so we don't have to introduce stream->buf_lock.

If stream->buf_lock is needed and mutex_destroy is a problem, another idea
would be to introduce it in gt->eu_stall so it doesn't need to be destroyed
when the stream fd is closed.

As I said, you can keep this as is, or whatever works for you and is
convenient for debug.

So I decided to do a quick POC to see if my suggestion above to get rid of
the circular locking dependency worked. And basically it does, with the
patch below (we have to ensure stream doesn't get freed and I haven't
deleted buf_lock), but you will get the idea. I reproduced the issue with
your kernel patches and IGT and made sure the patch below fixes it. So
buf_lock is not needed.

So with the patch below the circular locking dependency is gone. So let's
go with something like this, if you agree:

Maybe, as suggested above, move buf_poll_wq into gt->eu_stall (rather than
the stream), so it does not have to be destroyed when the stream fd is
closed. That way we can just call xe_eu_stall_stream_free() from
xe_eu_stall_stream_close().

And we'll alloc the workqueue in xe_eu_stall_init() and destroy it in
xe_eu_stall_fini(). This will minimize the changes.

If the workqueue is allocated in xe_eu_stall_init() and destroyed in
xe_eu_stall_fini(), there will be a EU stall workqueue even when EU
stall is not being used. Is that okay? I mean would an idle workqueue
consume any resources? Or would the code be more cleaner if we keep the
additional buf_lock?

A workqueue is just tiny amount of memory (similar to your
gt->eu_stall). Nothing is executing till a EU stall stream is present, so
just tiny amount of memory resources, no compute resourse. So let's go with
that, rather than the additional buf_lock. Thanks.

Basically buf_lock is not needed anyway, the workqueue can also be part of
the stream. I just suggested to put it in gt->eu_stall so that
xe_eu_stall_stream_free() can be used as is, otherwise more refactoring in
the code will be needed.
