This is a pile of patches which implements a rudimentary vendor agnostic gputop
tool based of the new DRM spec as documented in
Documentation/gpu/drm-usage-stats.rst.
First part of the series is code refactoring which should be reasonably stable.
I've tested it all while working on it both against intel_gpu_top and gputop.
Last patch is the actual tool itself. It works but it is rather rudimentary
which is hopefully good enough for a start.
Fundamental difference between intel_gpu_top and gputop is that the former is
centered around a single card and only shows processes belonging to it. Gputop
on the other hand has an idea to show all processes with DRM file descriptors
open and sort them into groups per card. It also makes no effort to provide
sorting modes, well any interactivity, or any pretty names for GPUs or engines.
It looks like this:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
I did test it as well with two cards and confirmed that too works.
Rob Clark also tested it with a patch which exports the respective data from the
msm driver and confirmed it works fine. Christian König tested it with in
progress patches for amdgpu and that worked as well.
v2:
* Fixed SPDX headers and added a bunch of code comments/docs throughout.

* [PATCH i-g-t 2/8] libdrmfdinfo: Allow specifying custom engine map

From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>
Instead of hard coding the engine names, allow a map of names to indices
to either be passed in or it gets auto-detected (less efficient) while
parsing.

* [Intel-gfx] [PATCH i-g-t 2/8] libdrmfdinfo: Allow specifying custom engine map

Instead of hard coding the engine names, allow a map of names to indices
to either be passed in or it gets auto-detected (less efficient) while
parsing.

* [PATCH i-g-t 6/8] libdrmclient/intel_gpu_top: Decouple hardcoded engine assumptions

From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>
Intel_gpu_top gets it's main engine configuration data via PMU probe and
uses that for per client view as well. Furthemore code so far assumed only
clients belonging from a single DRM card would be tracked in a single
clients list.
Break this inter-dependency by moving the engine data to be per client and
also have libdrmclient probe the engine configuration independently using
the previously added libdrmfdinfo facilities.

* [PATCH i-g-t 7/8] libdrmclient: Enforce client status sort order in the library

To: igt-dev, Intel-gfx, dri-devel; +Cc: Tvrtko Ursulin
From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>
Some libdrmclient operations require that inactive clients are last in the
list. Rather than relying on callers of the library sort routine to
implement their comparison callbacks correctly, enforce this order
directly in the library and let callers comparison callbacks concern
themselves only with ordering they are interested in.

* [igt-dev] [PATCH i-g-t 7/8] libdrmclient: Enforce client status sort order in the library
@ 2022-11-11 15:58 ` Tvrtko Ursulin

To: igt-dev, Intel-gfx, dri-devel; +Cc: Tvrtko Ursulin
From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>
Some libdrmclient operations require that inactive clients are last in the
list. Rather than relying on callers of the library sort routine to
implement their comparison callbacks correctly, enforce this order
directly in the library and let callers comparison callbacks concern
themselves only with ordering they are interested in.

* [PATCH i-g-t 8/8] gputop: Basic vendor agnostic GPU top tool

From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>
Rudimentary vendor agnostic example of how lib_igt_drm_clients can be used
to display a sorted by card and usage list of processes using GPUs.
Borrows a bit of code from intel_gpu_top but for now omits the fancy
features like interactive functionality, card selection, client
aggregation, sort modes, JSON output and pretty engine names. Also no
support for global GPU or system metrics.
On the other hand it shows clients from all DRM cards which
intel_gpu_top does not do.

* [Intel-gfx] [PATCH i-g-t 8/8] gputop: Basic vendor agnostic GPU top tool
@ 2022-11-11 15:58 ` Tvrtko Ursulin

From: Tvrtko Ursulin @ 2022-11-11 15:58 UTC (permalink / raw)
To: igt-dev, Intel-gfx, dri-devel
Cc: Rob Clark, Christian König, Christian König
From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>
Rudimentary vendor agnostic example of how lib_igt_drm_clients can be used
to display a sorted by card and usage list of processes using GPUs.
Borrows a bit of code from intel_gpu_top but for now omits the fancy
features like interactive functionality, card selection, client
aggregation, sort modes, JSON output and pretty engine names. Also no
support for global GPU or system metrics.
On the other hand it shows clients from all DRM cards which
intel_gpu_top does not do.

Hi,
please rebase and resend, also please change commit subject to start
with lib: or lib/[name of lib changed]: rest od commit description
For example, in 3/8 instead of
libdrmclients: Record client drm minor
write:
lib/igt_drm_clients: Record client drm minor
If there are more lib changes, use "lib: " alone, for example
in your 2/8 patch,

Hi,
please rebase and resend, also please change commit subject to start
with lib: or lib/[name of lib changed]: rest od commit description
For example, in 3/8 instead of
libdrmclients: Record client drm minor
write:
lib/igt_drm_clients: Record client drm minor
If there are more lib changes, use "lib: " alone, for example

Series should still apply as is so I don't think there is need to
re-send. It will only conflict if I get to merge the "Assorted
intel_gpu_top improvements" series first, in which case I can resend.

Again, if you agree there is no need to spam the list with a re-send
yet, review can continue against this version, and I will note to change
the above patch prefixes while doing the other changes the review is
bound to trigger.
