398 * CpuCP Primary Queue Packets
400 * During normal operation, the host's kernel driver needs to send various
401 * messages to CpuCP, usually either to SET some value into a H/W periphery or
402 * to GET the current value of some H/W periphery. For example, SET the
403 * frequency of MME/TPC and GET the value of the thermal sensor.
405 * These messages can be initiated either by the User application or by the
406 * host's driver itself, e.g. power management code. In either case, the
407 * communication from the host's driver to CpuCP will *always* be in
408 * synchronous mode, meaning that the host will send a single message and poll
409 * until the message was acknowledged and the results are ready (if results are
412 * This means that only a single message can be sent at a time and the host's
413 * driver must wait for its result before sending the next message. Having said
414 * that, because these are control messages which are sent in a relatively low
415 * frequency, this limitation seems acceptable. It's important to note that
416 * in case of multiple devices, messages to different devices *can* be sent
419 * The message, inputs/outputs (if relevant) and fence object will be located
420 * on the device DDR at an address that will be determined by the host's driver.
421 * During device initialization phase, the host will pass to CpuCP that address.
422 * Most of the message types will contain inputs/outputs inside the message
423 * itself. The common part of each message will contain the opcode of the
424 * message (its type) and a field representing a fence object.
426 * When the host's driver wishes to send a message to CPU CP, it will write the
427 * message contents to the device DDR, clear the fence object and then write to
428 * the PSOC_ARC1_AUX_SW_INTR, to issue interrupt 121 to ARC Management CPU.
430 * Upon receiving the interrupt (#121), CpuCP will read the message from the
431 * DDR. In case the message is a SET operation, CpuCP will first perform the
432 * operation and then write to the fence object on the device DDR. In case the
433 * message is a GET operation, CpuCP will first fill the results section on the
434 * device DDR and then write to the fence object. If an error occurred, CpuCP
435 * will fill the rc field with the right error code.
437 * In the meantime, the host's driver will poll on the fence object. Once the
438 * host sees that the fence object is signaled, it will read the results from
439 * the device DDR (if relevant) and resume the code execution in the host's
442 * To use QMAN packets, the opcode must be the QMAN opcode, shifted by 8
443 * so the value being put by the host's driver matches the value read by CpuCP
445 * Non-QMAN packets should be limited to values 1 through (2^8 - 1)

646 * boot sequence. the attestation data is also hashed with some unique
647 * number (nonce) provided by the host to prevent replay attacks.
648 * public key and certificate also provided as part of the FW response.

651 * Get monitors registers dump from the CpuCP kernel.
652 * The CPU will put the registers dump in the a buffer allocated by the driver
653 * which address is passed via the CpuCp packet. In addition, the host's driver
654 * passes the max size it allows the CpuCP to write to the structure, to prevent
655 * data corruption in case of mismatched driver/FW versions.
656 * Relevant only to Gaudi.
