- -/* - * CpuCP Primary Queue Packets - * - * During normal operation, the host's kernel driver needs to send various - * messages to CpuCP, usually either to SET some value into a H/W periphery or - * to GET the current value of some H/W periphery. For example, SET the - * frequency of MME/TPC and GET the value of the thermal sensor. - * - * These messages can be initiated either by the User application or by the - * host's driver itself, e.g. power management code. In either case, the - * communication from the host's driver to CpuCP will *always* be in - * synchronous mode, meaning that the host will send a single message and poll - * until the message was acknowledged and the results are ready (if results are - * needed). - * - * This means that only a single message can be sent at a time and the host's - * driver must wait for its result before sending the next message. Having said - * that, because these are control messages which are sent in a relatively low - * frequency, this limitation seems acceptable. It's important to note that - * in case of multiple devices, messages to different devices *can* be sent - * at the same time. - * - * The message, inputs/outputs (if relevant) and fence object will be located - * on the device DDR at an address that will be determined by the host's driver. - * During device initialization phase, the host will pass to CpuCP that address. - * Most of the message types will contain inputs/outputs inside the message - * itself. The common part of each message will contain the opcode of the - * message (its type) and a field representing a fence object. - * - * When the host's driver wishes to send a message to CPU CP, it will write the - * message contents to the device DDR, clear the fence object and then write to - * the PSOC_ARC1_AUX_SW_INTR, to issue interrupt 121 to ARC Management CPU. - * - * Upon receiving the interrupt (#121), CpuCP will read the message from the - * DDR. In case the message is a SET operation, CpuCP will first perform the - * operation and then write to the fence object on the device DDR. In case the - * message is a GET operation, CpuCP will first fill the results section on the - * device DDR and then write to the fence object. If an error occurred, CpuCP - * will fill the rc field with the right error code. - * - * In the meantime, the host's driver will poll on the fence object. Once the - * host sees that the fence object is signaled, it will read the results from - * the device DDR (if relevant) and resume the code execution in the host's - * driver. - * - * To use QMAN packets, the opcode must be the QMAN opcode, shifted by 8 - * so the value being put by the host's driver matches the value read by CpuCP - * - * Non-QMAN packets should be limited to values 1 through (2^8 - 1) - * - * Detailed description: - * - * CPUCP_PACKET_DISABLE_PCI_ACCESS - - * After receiving this packet the embedded CPU must NOT issue PCI - * transactions (read/write) towards the Host CPU.
