/** @brief Arguments for _mali_ukk_gp_start_job()
 *
 * To start a Vertex Processor job
 * - associate the request with a reference to a @c mali_gp_job_info by setting
 * user_job_ptr to the address of the @c mali_gp_job_info of the job.
 * - set @c priority to the priority of the @c mali_gp_job_info
 * - specify a timeout for the job by setting @c watchdog_msecs to the number of
 * milliseconds the job is allowed to run. Specifying a value of 0 selects the
 * default timeout in use by the device driver.
 * - copy the frame registers from the @c mali_gp_job_info into @c frame_registers.
 * - set the @c perf_counter_flag, @c perf_counter_src0 and @c perf_counter_src1 to zero
 * for a non-instrumented build. For an instrumented build you can use up
 * to two performance counters. Set the corresponding bit in @c perf_counter_flag
 * to enable them. @c perf_counter_src0 and @c perf_counter_src1 specify
 * the source of what needs to get counted (e.g. number of vertex loader
 * cache hits). For source id values, see ARM DDI0415A, Table 3-60.
 * - pass in the user-kernel context @c ctx that was returned from _mali_ukk_open()
 *
 * When @c _mali_ukk_gp_start_job() returns @c _MALI_OSK_ERR_OK, status contains the
 * result of the request (see \ref _mali_uk_start_job_status). If the job could
 * not get started (@c _MALI_UK_START_JOB_NOT_STARTED_DO_REQUEUE) it should be
 * tried again.
 *
 * After the job has started, @c _mali_wait_for_notification() will be notified
 * that the job finished or got suspended. It may get suspended due to
 * resource shortage. If it finished (see _mali_ukk_wait_for_notification())
 * the notification will contain a @c _mali_uk_gp_job_finished_s result. If
 * it got suspended the notification will contain a @c _mali_uk_gp_job_suspended_s
 * result.
 *
 * The @c _mali_uk_gp_job_finished_s contains the job status (see \ref _mali_uk_job_status),
 * the number of milliseconds the job took to render, and values of core registers
 * when the job finished (irq status, performance counters, renderer list
 * address). A job has finished succesfully when its status is
 * @c _MALI_UK_JOB_STATUS_FINISHED. If the hardware detected a timeout while rendering
 * the job, or software detected the job is taking more than watchdog_msecs to
 * complete, the status will indicate @c _MALI_UK_JOB_STATUS_HANG.
 * If the hardware detected a bus error while accessing memory associated with the
 * job, status will indicate @c _MALI_UK_JOB_STATUS_SEG_FAULT.
 * status will indicate @c _MALI_UK_JOB_STATUS_NOT_STARTED if the driver had to
 * stop the job but the job didn't start on the hardware yet, e.g. when the
 * driver shutdown.
 *
 * In case the job got suspended, @c _mali_uk_gp_job_suspended_s contains
 * the @c user_job_ptr identifier used to start the job with, the @c reason
 * why the job stalled (see \ref _maligp_job_suspended_reason) and a @c cookie
 * to identify the core on which the job stalled.  This @c cookie will be needed
 * when responding to this nofication by means of _mali_ukk_gp_suspend_response().
 * (see _mali_ukk_gp_suspend_response()). The response is either to abort or
 * resume the job. If the job got suspended due to an out of memory condition
 * you may be able to resolve this by providing more memory and resuming the job.

/** @brief Arguments for _mali_ukk_wait_for_notification()
 *
 * On successful return from _mali_ukk_wait_for_notification(), the members of
 * this structure will indicate the reason for notification.
 *
 * Specifically, the source of the notification can be identified by the
 * subsystem and id fields of the mali_uk_notification_type in the code.type
 * member. The type member is encoded in a way to divide up the types into a
 * subsystem field, and a per-subsystem ID field. See
 * _mali_uk_notification_type for more information.
 *
 * Interpreting the data union member depends on the notification type:
 *
 * - type == _MALI_NOTIFICATION_CORE_SHUTDOWN_IN_PROGRESS
 *     - The kernel side is shutting down. No further
 * _mali_uk_wait_for_notification() calls should be made.
 *     - In this case, the value of the data union member is undefined.
 *     - This is used to indicate to the user space client that it should close
 * the connection to the Mali Device Driver.
 * - type == _MALI_NOTIFICATION_PP_FINISHED
 *    - The notification data is of type _mali_uk_pp_job_finished_s. It contains the user_job_ptr
 * identifier used to start the job with, the job status, the number of milliseconds the job took to render,
 * and values of core registers when the job finished (irq status, performance counters, renderer list
 * address).
 *    - A job has finished succesfully when its status member is _MALI_UK_JOB_STATUS_FINISHED.
 *    - If the hardware detected a timeout while rendering the job, or software detected the job is
 * taking more than watchdog_msecs (see _mali_ukk_pp_start_job()) to complete, the status member will
 * indicate _MALI_UK_JOB_STATUS_HANG.
 *    - If the hardware detected a bus error while accessing memory associated with the job, status will
 * indicate _MALI_UK_JOB_STATUS_SEG_FAULT.
 *    - Status will indicate MALI_UK_JOB_STATUS_NOT_STARTED if the driver had to stop the job but the job
 * didn't start the hardware yet, e.g. when the driver closes.
 * - type == _MALI_NOTIFICATION_GP_FINISHED
 *     - The notification data is of type _mali_uk_gp_job_finished_s. The notification is similar to that of
 * type == _MALI_NOTIFICATION_PP_FINISHED, except that several other GP core register values are returned.
 * The status values have the same meaning for type == _MALI_NOTIFICATION_PP_FINISHED.
 * - type == _MALI_NOTIFICATION_GP_STALLED
 *     - The nofication data is of type _mali_uk_gp_job_suspended_s. It contains the user_job_ptr
 * identifier used to start the job with, the reason why the job stalled and a cookie to identify the core on
 * which the job stalled.
 *     - The reason member of gp_job_suspended is set to _MALIGP_JOB_SUSPENDED_OUT_OF_MEMORY
 * when the polygon list builder unit has run out of memory.

 * the CPU (which may be a constant offset from that used by Mali)

 *
 * The ukk_private word must be set to zero when calling from user-space. On
 * Kernel-side, the  OS implementation of the U/K interface can use it to
