1 In-kernel API for FPGA Programming
5 --------
7 The in-kernel API for FPGA programming is a combination of APIs from
8 FPGA manager, bridge, and regions.  The actual function used to
12 the FPGA manager and bridges.  It will:
15  * lock the mutex of the region's FPGA manager
18  * program the FPGA using info passed in :c:expr:`fpga_region->info`.
19  * re-enable the bridges
27 -------------------------------------
29 When the FPGA region driver probed, it was given a pointer to an FPGA manager
30 driver so it knows which manager to use.  The region also either has a list of
34 	#include <linux/fpga/fpga-mgr.h>
35 	#include <linux/fpga/fpga-region.h>
46 		return -ENOMEM;
49 	info->flags = FPGA_MGR_PARTIAL_RECONFIG;
52 	 * Indicate where the FPGA image is. This is pseudo-code; you're
57 		info->sgt = [your scatter gather table]
59 	} else if (image is in a buffer) {
61 		info->buf = [your image buffer]
62 		info->count = [image buffer size]
66 		info->firmware_name = devm_kstrdup(dev, firmware_name,
72 	region->info = info;
76 	region->info = NULL;
85 ---------------------------
87 * fpga_region_program_fpga() -  Program an FPGA
88 * fpga_image_info() -  Specifies what FPGA image to program
89 * fpga_image_info_alloc() -  Allocate an FPGA image info struct
90 * fpga_image_info_free() -  Free an FPGA image info struct
