Detailed Description

struct drm_xe_query_oa_units - describe OA units

If a query is made with a struct drm_xe_device_query where .query is equal to DRM_XE_DEVICE_QUERY_OA_UNITS, then the reply uses struct drm_xe_query_oa_units in .data.

OA unit properties for all OA units can be accessed using a code block such as the one below:

.. code-block:: C

struct drm_xe_query_oa_units *qoa; struct drm_xe_oa_unit *oau; u8 *poau;

// malloc qoa and issue DRM_XE_DEVICE_QUERY_OA_UNITS. Then: poau = (u8 *)&qoa->oa_units[0]; for (int i = 0; i < qoa->num_oa_units; i++) { oau = (struct drm_xe_oa_unit *)poau; // Access 'struct drm_xe_oa_unit' fields here poau += sizeof(*oau) + oau->num_engines * sizeof(oau->eci[0]); }
