26  * SVC_NUM_CHANNEL - number of channel supported by service layer driver
33  * service layer will return error to FPGA manager when timeout occurs,
42 /* stratix10 service layer clients */
62  * struct stratix10_svc_sh_memory - service shared memory structure
72  * Service layer driver uses the physical address and size to create a memory
73  * pool, then allocates data buffer from that memory pool for service client.
83  * struct stratix10_svc_data_mem - service memory structure
90  * been allocated or freed from the memory pool. Service layer driver also
101  * struct stratix10_svc_data - service data structure
102  * @chan: service channel
107  * @command: service command requested by client
111  * This struct is used in service FIFO for inter-process communication.
125  * struct stratix10_svc_controller - service controller
127  * @chans: array of service channels
129  * @num_active_client: number of active service client
133  * @svc_fifo: a queue for storing service message data
135  * @svc_fifo_lock: protect access to service message data queue
138  * This struct is used to create communication channels for service clients, to
156  * struct stratix10_svc_chan - service communication channel
157  * @ctrl: pointer to service controller which is the provider of this channel
158  * @scl: pointer to service client which owns the channel
159  * @name: service client name associated with the channel
162  * This struct is used by service client to communicate with service layer, each
163  * service client has its own channel created by service controller.
197  * @ctrl: pointer to service layer controller
198  * @p_data: pointer to service data structure
199  * @cb_data: pointer to callback data structure to service client
202  * back to service client (FPGA manager, etc) for reuse.
243  * @ctrl: pointer to service layer controller
244  * @p_data: pointer to service data structure
245  * @cb_data: pointer to callback data structure to service client
310  * @p_data: pointer to service data structure
311  * @cb_data: pointer to callback data structure to service client
314  * Send back the correspond status to the service clients.
385  * Service layer driver creates stratix10_svc_smc_hvc_call kthread on CPU
669  * Service layer driver creates stratix10_svc_smc_hvc_shm kthread on CPU
703  * @pdev: pointer to service layer device
704  * @sh_memory: pointer to service shared memory structure
751  * @pdev: pointer to service layer device
752  * @sh_memory: pointer to service shared memory structure
874  * stratix10_svc_request_channel_byname() - request a service channel
875  * @client: pointer to service client
876  * @name: service client name
878  * This function is used by service client to request a service channel.
926  * stratix10_svc_free_channel() - free service channel
927  * @chan: service channel to be freed
929  * This function is used by service client to free a service channel.
945  * @chan: service channel assigned to the client
949  * This function is used by service client to add a message to the service
1037  * stratix10_svc_done() - complete service request transactions
1038  * @chan: service channel assigned to the client
1041  * or there is an error in the request process. It allows the service layer
1057  * @chan: service channel assigned to the client
1058  * @size: memory size requested by a specific service client
1060  * Service layer allocates the requested number of bytes buffer from the
1061  * memory pool, service client uses this function to get allocated buffers.
1098  * @chan: service channel assigned to the client
1101  * This function is used by service client to free allocated buffers.
