We had previously enabled render and compute OA units. Enable media OA
units with this series.
v3: Introduce DRM_XE_OA_UNIT_TYPE_OAM_SAG
v2: Added Patch 5
Ashutosh Dixit (5):
drm/xe/oa/uapi: Expose media OA units
drm/xe/oa: Print hwe to OA unit mapping
drm/xe/oa: Introduce stream->oa_unit
drm/xe/oa: Assign hwe for OAM_SAG
drm/xe/oa: Enable OAM latency measurement

On Xe2+ platforms, media engines are attached to "SCMI" OA media (OAM)
units. One or more SCMI OAM units might be present on a platform. In
addition there is another OAM unit for global events, called
OAM-SAG. Performance metrics for media workloads can be obtained from these
OAM units, similar to OAG.
Expose these OAM units for userspace to use. OAM-SAG is exposed as an OA
unit without any attached engines.
Bspec: 70819, 67103, 63844, 72572, 74476, 61284
v2: Fix xe_gt_WARN_ON in __hwe_oam_unit for < 12.7 platforms
v3: Return XE_OA_UNIT_INVALID for < 12.7 to indicate no OAM units
v4: Move xe_oa_print_oa_units() to separate patch
v5: Introduce DRM_XE_OA_UNIT_TYPE_OAM_SAG

Previously, the oa_unit associated with an OA stream was derived from hwe
associated with the stream (stream->hwe->oa_unit). This breaks with OAM_SAG
since OAM_SAG does not have any attached hardware engines. Resolve this by
introducing stream->oa_unit and stop depending on stream->hwe.

Because OAM_SAG doesn't have an attached hwe, assign another hwe belonging
to the same gt (and different OAM unit) to OAM_SAG. A hwe is needed for
batch submissions to program OA HW.

You could just drop the case XE_ENGINE_CLASS_OTHER in caller

Not sure if for_each_hw_engine omits reserved engines. If we should not
use reserved engines, we should check for that here using
xe_hw_engine_is_reserved(). Also, maybe we should only try to submit the
batch on engine classes supported by OA. Submitting the batch from other
engines (like bcs) is not really tested.

Yes, I was doing that initially. But then I changed to this to make it
*explicit* that even when GSC is attached to OAM-SAG, it is not assigned to
any OA unit. Because it is really an exception, as the comment above
explains.
If you are asking why XE_ENGINE_CLASS_OTHER calls __hwe_oam_unit(), that is
because GSC is present on media GT and is used for HuC authentication
etc. (also related to media).
If you insist I can change it, but I think it is better to leave as
is. This way it is part of the code, the other way it will be in a comment
(and would be implicit and later people might wonder if it is missed). Let
me know.

To map any possible VCS (VCS0 - VCS7) to OAM-SCMI-0 or OAM-SCMI-1 we need
the '& 0x1'.

Similarly, to map any possible VECS (VECS0 - VECS3) to OAM-SCMI-0 or 1 we
need the '& 0x1'.

On Xe2+ platforms, media engines are attached to "SCMI" OA media (OAM)
units. One or more SCMI OAM units might be present on a platform. In
addition there is another OAM unit for global events, called
OAM-SAG. Performance metrics for media workloads can be obtained from these
OAM units, similar to OAG.
Expose these OAM units for userspace to use. OAM-SAG is exposed as an OA
unit without any attached engines.
Bspec: 70819, 67103, 63844, 72572, 74476, 61284
v2: Fix xe_gt_WARN_ON in __hwe_oam_unit for < 12.7 platforms
v3: Return XE_OA_UNIT_INVALID for < 12.7 to indicate no OAM units
v4: Move xe_oa_print_oa_units() to separate patch
v5: Introduce DRM_XE_OA_UNIT_TYPE_OAM_SAG

It does not, they have to be omitted separately.

Reserved means those engines are not available for user space. I think it
is ok for the kernel to use them, at least in some cases reserved means
reserved for the kernel. Reserved engines are different from fused off
engines and for_each_hw_engine() skips fused off engines (via
xe_hw_engine_is_valid()).
I was looking at OA code and looks like in OA we have assumed (mostly
without realizing it :/) that reserved engines can be used by OA internally
and reserved engines are attached to OA units. But we don't expose reserved
engines to userspace in the OA query.
So along those lines, I have skipped checking for reserved engines here. If
we really need to skip reserved engines, that should be done globally in OA
code (don't attach reserved engines to OA units itself), otherwise it will
unnecessarily mess up the code. So for now I am assuming OA code reserved
engine usage is ok.

I have added this check now, good catch:
if (!hwe->oa_unit)
continue;
Thanks.

Thanks Umesh. I also just added a DRM_XE_OA_CAPS_OAM capability also to
this patch. I was debating initially, since userland will see at least 2
OAM units after this series is merged, so that is the way to figure out if
correct OAM support is present in the driver. But then went ahead and added
DRM_XE_OA_CAPS_OAM, since that's how we've been doing things: if you change
uapi, you add a capability. Thanks.

On Xe2+ platforms, media engines are attached to "SCMI" OA media (OAM)
units. One or more SCMI OAM units might be present on a platform. In
addition there is another OAM unit for global events, called
OAM-SAG. Performance metrics for media workloads can be obtained from these
OAM units, similar to OAG.
Expose these OAM units for userspace to use. OAM-SAG is exposed as an OA
unit without any attached engines.
Bspec: 70819, 67103, 63844, 72572, 74476, 61284
v2: Fix xe_gt_WARN_ON in __hwe_oam_unit for < 12.7 platforms
v3: Return XE_OA_UNIT_INVALID for < 12.7 to indicate no OAM units
v4: Move xe_oa_print_oa_units() to separate patch
v5: Introduce DRM_XE_OA_UNIT_TYPE_OAM_SAG
v6: Introduce DRM_XE_OA_CAPS_OAM
