[PATCH 0/4] Refactor xe_exec_queue_create to fix user extensions

[Brian Welty <brian.welty@intel.com>]

We have an issue in that exec_queue_user_extensions are applied too late.
In the case of USM properties, these need to be set prior to xe_lrc_init().

Split __xe_exec_queue_create() into two functions, alloc and init.
Setting of exec_queue user extensions is moved from the end of the ioctl
function earlier, into __xe_exec_queue_alloc(). This fixes above issue
with USM properties being set too late.

However, in order to apply user extensions this early, we can no longer
call q->ops functions.  Instead, make it more efficient. User extension
functions can simply update the q->sched_props values and they will be
applied by the backend during q->ops->init().

Note to reviewers, perhaps review the last patch first.

  drm/xe: Add exec_queue.sched_props.job_timeout_ms
