46  * This header defines the in-kernel API for Innova FPGA client drivers.
55  * struct mlx5_fpga_client - Describes an Innova client driver
70 	 * Any SBU-specific initialization should happen at this stage
78 	 * SBU-specific cleanup should happen at this stage
95  * struct mlx5_fpga_dma_entry - A scatter-gather DMA entry
102 	/** @dma_addr: Private member. Physical DMA-mapped address of the data */
107  * struct mlx5_fpga_dma_buf - A packet buffer
108  * May contain up to 2 scatter-gather data entries
113 	/** @sg: Scatter-gather entries pointing to the data in memory */
130  * struct mlx5_fpga_conn_attr - FPGA connection attributes
143 	 * buf is guaranteed to only contain a single scatter-gather entry.
145 	 * When this callback returns, the packet buffer may be re-used for
153  * mlx5_fpga_client_register() - Register a client driver
162  * mlx5_fpga_client_unregister() - Unregister a client driver
172  * mlx5_fpga_device_reload() - Force the FPGA to reload its synthesis from flash
188  * mlx5_fpga_flash_select() - Select the current active flash
194  * This setting is volatile and is reset upon reboot or power-cycle
202  * mlx5_fpga_sbu_conn_create() - Initialize a new FPGA SBU connection
220  * mlx5_fpga_sbu_conn_destroy() - Destroy an FPGA SBU connection
229  * mlx5_fpga_sbu_conn_sendmsg() - Queue the transmission of a packet
244  * mlx5_fpga_mem_read() - Read from FPGA memory address space
253  * Large reads may be performed internally as several non-atomic operations.
262  * mlx5_fpga_mem_write() - Write to FPGA memory address space
271  * Large writes may be performed internally as several non-atomic operations.
280  * mlx5_fpga_get_sbu_caps() - Read the SBU capabilities
286  * The format of the capabilities buffer is SBU-dependent.
289  *         -EINVAL if the buffer is not large enough to contain SBU caps
295  * mlx5_fpga_ddr_size_get() - Retrieve the size of FPGA DDR
303  * mlx5_fpga_ddr_base_get() - Retrieve the base address of FPGA DDR
311  * mlx5_fpga_client_data_set() - Attach client-defined private value to a device
316  * Client driver may use the private value for storing device-specific
325  * mlx5_fpga_client_data_get() - Retrieve client-defined private value
329  * Client driver may use the private value for storing device-specific
338  * mlx5_fpga_device_query() - Query FPGA device state information
348  * mlx5_fpga_dev() - Retrieve FPGA device structure
357  * mlx5_fpga_temperature() - Retrieve FPGA sensor of temperature
