[Intel-gfx] [RFC 0/8] Per client GPU stats

[Intel-gfx] [RFC 0/8] Per client GPU stats

[Tvrtko Ursulin]

From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>

Same old work but now rebased and series ending with some DRM docs proposing
the common specification which should enable nice common userspace tools to be
written.

For the moment I only have intel_gpu_top converted to use this and that seems to
work okay.

v2:
 * Added prototype of possible amdgpu changes and spec updates to align with the
   common spec.

v3:
 * Documented that 'drm-driver' tag shall correspond with
   struct drm_driver.name.

Tvrtko Ursulin (8):
  drm/i915: Explicitly track DRM clients
  drm/i915: Make GEM contexts track DRM clients
  drm/i915: Track runtime spent in closed and unreachable GEM contexts
  drm/i915: Track all user contexts per client
  drm/i915: Track context current active time
  drm: Document fdinfo format specification
  drm/i915: Expose client engine utilisation via fdinfo
  drm/amdgpu: Convert to common fdinfo format

[Intel-gfx] [RFC 1/8] drm/i915: Explicitly track DRM clients

[Tvrtko Ursulin]

From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>

Tracking DRM clients more explicitly will allow later patches to
accumulate past and current GPU usage in a centralised place and also
consolidate access to owning task pid/name.

Unique client id is also assigned for the purpose of distinguishing/
consolidating between multiple file descriptors owned by the same process.

v2:
 Chris Wilson:
 * Enclose new members into dedicated structs.
 * Protect against failed sysfs registration.

v3:
 * sysfs_attr_init.

v4:
 * Fix for internal clients.

v5:
 * Use cyclic ida for client id. (Chris)
 * Do not leak pid reference. (Chris)
 * Tidy code with some locals.

v6:
 * Use xa_alloc_cyclic to simplify locking. (Chris)
 * No need to unregister individial sysfs files. (Chris)
 * Rebase on top of fpriv kref.
 * Track client closed status and reflect in sysfs.

v7:
 * Make drm_client more standalone concept.

v8:
 * Simplify sysfs show. (Chris)
 * Always track name and pid.

v9:
 * Fix cyclic id assignment.

v10:
 * No need for a mutex around xa_alloc_cyclic.
 * Refactor sysfs into own function.
 * Unregister sysfs before freeing pid and name.
 * Move clients setup into own function.

v11:
 * Call clients init directly from driver init. (Chris)

v12:
 * Do not fail client add on id wrap. (Maciej)

v13 (Lucas): Rebase.

v14:
 * Dropped sysfs bits.

v15:
 * Dropped tracking of pid/ and name.
 * Dropped RCU freeing of the client object.

[Intel-gfx] [RFC 2/8] drm/i915: Make GEM contexts track DRM clients

[Tvrtko Ursulin]

From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>

Make GEM contexts keep a reference to i915_drm_client for the whole of
of their lifetime which will come handy in following patches.

v2: Don't bother supporting selftests contexts from debugfs. (Chris)
v3 (Lucas): Finish constructing ctx before adding it to the list
v4 (Ram): Rebase.
v5: Trivial rebase for proto ctx changes.
v6: Rebase after clients no longer track name and pid.

[Intel-gfx] [RFC 3/8] drm/i915: Track runtime spent in closed and unreachable GEM contexts

[Tvrtko Ursulin]

From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>

As contexts are abandoned we want to remember how much GPU time they used
(per class) so later we can used it for smarter purposes.

As GEM contexts are closed we want to have the DRM client remember how
much GPU time they used (per class) so later we can used it for smarter
purposes.

[Intel-gfx] [RFC 4/8] drm/i915: Track all user contexts per client

[Tvrtko Ursulin]

From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>

We soon want to start answering questions like how much GPU time is the
context belonging to a client which exited still using.

To enable this we start tracking all context belonging to a client on a
separate list.

[Intel-gfx] [RFC 5/8] drm/i915: Track context current active time

[Tvrtko Ursulin]

From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>

Track context active (on hardware) status together with the start
timestamp.

This will be used to provide better granularity of context
runtime reporting in conjunction with already tracked pphwsp accumulated
runtime.

The latter is only updated on context save so does not give us visibility
to any currently executing work.

As part of the patch the existing runtime tracking data is moved under the
new ce->stats member and updated under the seqlock. This provides the
ability to atomically read out accumulated plus active runtime.

v2:
 * Rename and make __intel_context_get_active_time unlocked.

v3:
 * Use GRAPHICS_VER.

[Intel-gfx] [RFC 6/8] drm: Document fdinfo format specification

[Tvrtko Ursulin]

From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>

Proposal to standardise the fdinfo text format as optionally output by DRM
drivers.

Idea is that a simple but, well defined, spec will enable generic
userspace tools to be written while at the same time avoiding a more heavy
handed approach of adding a mid-layer to DRM.

i915 implements a subset of the spec, everything apart from the memory
stats currently, and a matching intel_gpu_top tool exists.

Open is to see if AMD can migrate to using the proposed GPU utilisation
key-value pairs, or if they are not workable to see whether to go
vendor specific, or if a standardised  alternative can be found which is
workable for both drivers.

Same for the memory utilisation key-value pairs proposal.

v2:
 * Update for removal of name and pid.

v3:
 * 'Drm-driver' tag will be obtained from struct drm_driver.name. (Daniel)

+
+======================
+DRM client usage stats
+======================
+
+DRM drivers can choose to export partly standardised text output via the
+`fops->show_fdinfo()` as part of the driver specific file operations registered
+in the `struct drm_driver` object registered with the DRM core.
+
+One purpose of this output is to enable writing as generic as practicaly
+feasible `top(1)` like userspace monitoring tools.
+
+Given the differences between various DRM drivers the specification of the
+output is split between common and driver specific parts. Having said that,
+wherever possible effort should still be made to standardise as much as
+possible.
+
+File format specification
+=========================
+
+- File shall contain one key value pair per one line of text.
+- Colon character (`:`) must be used to delimit keys and values.
+- All keys shall be prefixed with `drm-`.
+- Whitespace between the delimiter and first non-whitespace character shall be
+  ignored when parsing.
+- Neither keys or values are allowed to contain whitespace characters.
+- Numerical key value pairs can end with optional unit string.
+- Data type of the value is fixed as defined in the specification.
+
+Key types
+---------
+
+1. Mandatory, fully standardised.
+2. Optional, fully standardised.
+3. Driver specific.
+
+Data types
+----------
+
+- <uint> - Unsigned integer without defining the maximum value.
+- <str> - String excluding any above defined reserved characters or whitespace.
+
+Mandatory fully standardised keys
+---------------------------------
+
+- drm-driver: <str>
+
+String shall contain the name this driver registered as via the respective
+`struct drm_driver` data structure.
+
+Optional fully standardised keys
+--------------------------------
+
+- drm-pdev: <aaaa:bb.cc.d>
+
+For PCI devices this should contain the PCI slot address of the device in
+question.
+
+- drm-client-id: <uint>
+
+Unique value relating to the open DRM file descriptor used to distinguish
+duplicated and shared file descriptors. Conceptually the value should map 1:1
+to the in kernel representation of `struct drm_file` instances.
+
+Uniqueness of the value shall be either globally unique, or unique within the
+scope of each device, in which case `drm-pdev` shall be present as well.
+
+Userspace should make sure to not double account any usage statistics by using
+the above described criteria in order to associate data to individual clients.
+
+- drm-engine-<str>: <uint> ns
+
+GPUs usually contain multiple execution engines. Each shall be given a stable
+and unique name (str), with possible values documented in the driver specific
+documentation.
+
+Value shall be in specified time units which the respective GPU engine spent
+busy executing workloads belonging to this client.
+
+Values are not required to be constantly monotonic if it makes the driver
+implementation easier, but are required to catch up with the previously reported
+larger value within a reasonable period. Upon observing a value lower than what
+was previously read, userspace is expected to stay with that larger previous
+value until a monotonic update is seen.
+
+- drm-memory-<str>: <uint> [KiB|MiB]
+
+Each possible memory type which can be used to store buffer objects by the
+GPU in question shall be given a stable and unique name to be returned as the
+string here.
+
+Value shall reflect the amount of storage currently consumed by the buffer
+object belong to this client, in the respective memory region.
+
+Default unit shall be bytes with optional unit specifiers of 'KiB' or 'MiB'
+indicating kibi- or mebi-bytes.

I'm not an expert on that stuff, but as far as I can see this totally 
makes sense to me.

Feel free to add an Acked-by: Christian König <christian.koenig@amd.com> 
to those three patches.

Christian.

Thanks!

However note that the last one is full of TODO markers, including the 
commit message, where I was hoping to nudge the feature owners of the 
amdgpu side to fill in the blanks in my understanding of how things work 
over there. At least the different semantics need to be documented so 
random userspace can interpret the amdgpu values correctly.

Or alternatively I drop the last patch and if someone is interested they 
can resurrect and complete it at their leisure.

Just not sure how Daniel would accept this since his push was to gate 
i915 addition behind a drive for common solution.

Regards,

Tvrtko

Yeah, that's the reason why I only dare to give an ack. David is driving 
this at AMD.

If you ask me exposing ns like the i915 wants to do is perfectly 
sufficient for us as well.

[Intel-gfx] [RFC 7/8] drm/i915: Expose client engine utilisation via fdinfo

[Tvrtko Ursulin]

From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>

Similar to AMD commit
874442541133 ("drm/amdgpu: Add show_fdinfo() interface"), using the
infrastructure added in previous patches, we add basic client info
and GPU engine utilisation for i915.

Example of the output:

  pos:    0
  flags:  0100002
  mnt_id: 21
  drm-driver: i915
  drm-pdev:   0000:00:02.0
  drm-client-id:      7
  drm-engine-render:  9288864723 ns
  drm-engine-copy:    2035071108 ns
  drm-engine-video:   0 ns
  drm-engine-video-enhance:   0 ns

v2:
 * Update for removal of name and pid.

v3:
 * Use drm_driver.name.

[Intel-gfx] [RFC 8/8] drm/amdgpu: Convert to common fdinfo format

[Tvrtko Ursulin]

From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>

Convert fdinfo format to one documented in drm-usage-stats.rst.

Opens:
 * Does it work for AMD?
 * What are the semantics of AMD engine utilisation reported in percents?
   Can it align with what i915 does or needs to document the alternative
   in the specification document?
