No functional change in this patch. Let's ensure all of our structs are documented and with a certain standard. Also, let's have an overview and list of IOCTLs as the very beginning of the generated HTML doc. v2: Nits (Lucas De Marchi) Signed-off-by:

This patch doesn't modify any text or uapi entries themselves. It only move things up and down aiming a better organization of the uAPI. While fixing the documentation I noticed that query_engine_cs_cycles was in the middle of the memory_region info. Then I noticed more mismatches on the order when compared to the order of the IOCTL and QUERY entries declaration. So this patch aims to bring some order to the uAPI so it gets easier to read and the documentation generated in the end is able to tell a consistent story. Overall order: 1. IOCTL definition 2. Extension definition and helper structs 3. IOCTL's Query structs in the order of the Query's entries. 4. The rest of IOCTL structs in the order of IOCTL declaration. 5. uEvents Signed-off-by:

As there is no direct way to make comments of constants directly visible in the kernel doc, move them to the description of the structure where they can be used. By doing so they appear in the "Description" section of the struct documentation. v2: Remove DRM_XE_UFENCE_WAIT_MASK_* (Francois Dugast) Reviewed-by:

Remove concept of async vs sync VM bind queues, rather make all binds async. The following bits have dropped from the uAPI: DRM_XE_ENGINE_CLASS_VM_BIND_ASYNC DRM_XE_ENGINE_CLASS_VM_BIND_SYNC DRM_XE_VM_CREATE_FLAG_ASYNC_DEFAULT DRM_XE_VM_BIND_FLAG_ASYNC To implement sync binds the UMD is expected to use the out-fence interface. v2: Send correct version v3: Drop drm_xe_syncs Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Cc: Thomas Hellström <thomas.hellstrom@linux.intel.com> Cc: Francois Dugast <francois.dugast@intel.com> Signed-off-by:

remove the num_engines/instances members from drm_xe_wait_user_fence structure and add a exec_queue_id member Right now this is only checking if the engine list is sane and nothing else. In the end every operation with this IOCTL is a soft check. So, let's formalize that and only use this IOCTL to wait on the fence. exec_queue_id member will help to user space to get proper error code from kernel while in exec_queue reset Signed-off-by:

These offsets are primarily used as parameters for the engine register definitions, so it makes more sense to define them in the engine header rather than the general register header. Reviewed-by:

Although we only work with the RCS instances today, the FF_SLICE_CS_CHICKEN1[1,2] CS_DEBUG_MODE1, CS_CHICKEN1, and FF_THREAD_MODE registers all have instances on both the RCS and CCS engines. Convert these to parameterized macros and move them to the engine register header. Reviewed-by:

We don't use this suffix on any other registers, and it isn't part of the register's official name either, so drop it for consistency. While at it, move the register definition slightly so that it isn't separating RING_CMD_CCTL's definition from its fields. Reviewed-by:

Incase of bo move from PL_TT to PL_SYSTEM these pages will be used to store ccs metadata from flat ccs. And during bo move to PL_TT from PL_SYSTEM the metadata will be copied from extra pages to flat ccs.

The engine register header wound up with two definitions for RING_MAX_NONPRIV_SLOTS, likely due to a rebase mistake. Keep the definition that's in an appropriate place (i.e., with the FORCE_TO_NONPRIV register definition) and remove the other. Reviewed-by:

The idea being out-syncs can signal indicating all previous operations on the bind queue are complete. An example use case of this would be support for implementing vkQueueWaitIdle easily. All in-syncs are waited on before signaling out-syncs. This is implemented by forming a composite software fence of in-syncs and installing this fence in the out-syncs and exec queue last fence slot. The last fence must be added as a dependency for jobs on user exec queues as it is possible for the last fence to be a composite software fence (unordered, ioctl with zero bb or binds) rather than hardware fence (ordered, previous job on queue).
