* Command Submission
*
* To submit work to the device, the user need to call this IOCTL with a set
* of JOBS. That set of JOBS constitutes a CS object.
* Each JOB will be enqueued on a specific queue, according to the user's input.
* There can be more then one JOB per queue.
*
* The CS IOCTL will receive two sets of JOBS. One set is for "restore" phase
* and a second set is for "execution" phase.
* The JOBS on the "restore" phase are enqueued only after context-switch
* (or if its the first CS for this context). The user can also order the
* driver to run the "restore" phase explicitly
*
* Goya/Gaudi:
* There are two types of queues - external and internal. External queues
* are DMA queues which transfer data from/to the Host. All other queues are
* internal. The driver will get completion notifications from the device only
* on JOBS which are enqueued in the external queues.
*
* Greco onwards:
* There is a single type of queue for all types of engines, either DMA engines
* for transfers from/to the host or inside the device, or compute engines.
* The driver will get completion notifications from the device for all queues.
*
* For jobs on external queues, the user needs to create command buffers
* through the CB ioctl and give the CB's handle to the CS ioctl. For jobs on
* internal queues, the user needs to prepare a "command buffer" with packets
* on either the device SRAM/DRAM or the host, and give the device address of
* that buffer to the CS ioctl.
* For jobs on H/W queues both options of command buffers are valid.
*
* This IOCTL is asynchronous in regard to the actual execution of the CS. This
* means it returns immediately after ALL the JOBS were enqueued on their
* relevant queues. Therefore, the user mustn't assume the CS has been completed
* or has even started to execute.
*
* Upon successful enqueue, the IOCTL returns a sequence number which the user
* can use with the "Wait for CS" IOCTL to check whether the handle's CS
* non-internal JOBS have been completed. Note that if the CS has internal JOBS
* which can execute AFTER the external JOBS have finished, the driver might
* report that the CS has finished executing BEFORE the internal JOBS have
* actually finished executing.
*
* Even though the sequence number increments per CS, the user can NOT
* automatically assume that if CS with sequence number N finished, then CS
* with sequence number N-1 also finished. The user can make this assumption if
* and only if CS N and CS N-1 are exactly the same (same CBs for the same
* queues).

* inside the kernel until the CS has finished or until the user-requested
* timeout has expired.
*
* If the timeout value is 0, the driver won't sleep at all. It will check
* the status of the CS and return immediately
*
* The return value of the IOCTL is a standard Linux error code. The possible
* values are:
*
* EINTR - Kernel waiting has been interrupted, e.g. due to OS signal
* that the user process received
* ETIMEDOUT - The CS has caused a timeout on the device
* EIO - The CS was aborted (usually because the device was reset)
* ENODEV - The device wants to do hard-reset (so user need to close FD)
*
* The driver also returns a custom define in case the IOCTL call returned 0.
* The define can be one of the following:
*
* HL_WAIT_CS_STATUS_COMPLETED - The CS has been completed successfully (0)
* HL_WAIT_CS_STATUS_BUSY - The CS is still executing (0)
* HL_WAIT_CS_STATUS_TIMEDOUT - The CS has caused a timeout on the device
