/* * 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.
