| * 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 |

| * ENODEV - The device wants to do hard-reset (so user need to close FD) |
