408 409/* 410 * CpuCP Primary Queue Packets 411 * 412 * During normal operation, the host's kernel driver needs to send various 413 * messages to CpuCP, usually either to SET some value into a H/W periphery or 414 * to GET the current value of some H/W periphery. For example, SET the 415 * frequency of MME/TPC and GET the value of the thermal sensor. 416 * 417 * These messages can be initiated either by the User application or by the 418 * host's driver itself, e.g. power management code. In either case, the 419 * communication from the host's driver to CpuCP will *always* be in 420 * synchronous mode, meaning that the host will send a single message and poll 421 * until the message was acknowledged and the results are ready (if results are 422 * needed). 423 * 424 * This means that only a single message can be sent at a time and the host's 425 * driver must wait for its result before sending the next message. Having said 426 * that, because these are control messages which are sent in a relatively low 427 * frequency, this limitation seems acceptable. It's important to note that 428 * in case of multiple devices, messages to different devices *can* be sent 429 * at the same time. 430 * 431 * The message, inputs/outputs (if relevant) and fence object will be located 432 * on the device DDR at an address that will be determined by the host's driver. 433 * During device initialization phase, the host will pass to CpuCP that address. 434 * Most of the message types will contain inputs/outputs inside the message 435 * itself. The common part of each message will contain the opcode of the 436 * message (its type) and a field representing a fence object. 437 * 438 * When the host's driver wishes to send a message to CPU CP, it will write the 439 * message contents to the device DDR, clear the fence object and then write to 440 * the PSOC_ARC1_AUX_SW_INTR, to issue interrupt 121 to ARC Management CPU. 441 * 442 * Upon receiving the interrupt (#121), CpuCP will read the message from the 443 * DDR. In case the message is a SET operation, CpuCP will first perform the 444 * operation and then write to the fence object on the device DDR. In case the 445 * message is a GET operation, CpuCP will first fill the results section on the 446 * device DDR and then write to the fence object. If an error occurred, CpuCP 447 * will fill the rc field with the right error code. 448 * 449 * In the meantime, the host's driver will poll on the fence object. Once the 450 * host sees that the fence object is signaled, it will read the results from 451 * the device DDR (if relevant) and resume the code execution in the host's 452 * driver. 453 * 454 * To use QMAN packets, the opcode must be the QMAN opcode, shifted by 8 455 * so the value being put by the host's driver matches the value read by CpuCP 456 * 457 * Non-QMAN packets should be limited to values 1 through (2^8 - 1) 458 * 459 * Detailed description: 460 * 461 * CPUCP_PACKET_DISABLE_PCI_ACCESS - 462 * After receiving this packet the embedded CPU must NOT issue PCI 463 * transactions (read/write) towards the Host CPU.
