For example, SET the 152 * frequency of MME/TPC and GET the value of the thermal sensor. 153 * 154 * These messages can be initiated either by the User application or by the 155 * host's driver itself, e.g. power management code. In either case, the 156 * communication from the host's driver to CpuCP will *always* be in 157 * synchronous mode, meaning that the host will send a single message and poll 158 * until the message was acknowledged and the results are ready (if results are 159 * needed). 160 * 161 * This means that only a single message can be sent at a time and the host's 162 * driver must wait for its result before sending the next message. Having said 163 * that, because these are control messages which are sent in a relatively low 164 * frequency, this limitation seems acceptable. It's important to note that 165 * in case of multiple devices, messages to different devices *can* be sent 166 * at the same time. 167 * 168 * The message, inputs/outputs (if relevant) and fence object will be located 169 * on the device DDR at an address that will be determined by the host's driver. 170 * During device initialization phase, the host will pass to CpuCP that address. 171 * Most of the message types will contain inputs/outputs inside the message 172 * itself. The common part of each message will contain the opcode of the 173 * message (its type) and a field representing a fence object. 174 * 175 * When the host's driver wishes to send a message to CPU CP, it will write the 176 * message contents to the device DDR, clear the fence object and then write to 177 * the PSOC_ARC1_AUX_SW_INTR, to issue interrupt 121 to ARC Management CPU. 178 * 179 * Upon receiving the interrupt (#121), CpuCP will read the message from the 180 * DDR. In case the message is a SET operation, CpuCP will first perform the 181 * operation and then write to the fence object on the device DDR. In case the 182 * message is a GET operation, CpuCP will first fill the results section on the 183 * device DDR and then write to the fence object. If an error occurred, CpuCP 184 * will fill the rc field with the right error code. 185 * 186 * In the meantime, the host's driver will poll on the fence object. Once the 187 * host sees that the fence object is signaled, it will read the results from 188 * the device DDR (if relevant) and resume the code execution in the host's 189 * driver. 190 * 191 * To use QMAN packets, the opcode must be the QMAN opcode, shifted by 8 192 * so the value being put by the host's driver matches the value read by CpuCP 193 * 194 * Non-QMAN packets should be limited to values 1 through (2^8 - 1) 195 * 196 * Detailed description: 197 * 198 * CPUCP_PACKET_DISABLE_PCI_ACCESS - 199 * After receiving this packet the embedded CPU must NOT issue PCI 200 * transactions (read/write) towards the Host CPU.
