97730bbb - firmware_loader: Add firmware-upload support

Thu, 21 Apr 2022 21:22:00 +0000

firmware_loader: Add firmware-upload supportExtend the firmware subsystem to support a persistent sysfs interface thatuserspace may use to initiate a firmware update. For example, FPGA basedPCIe cards load firmware and FPGA images from local FLASH when the cardboots. The images in FLASH may be updated with new images provided by theuser at his/her convenience.A device driver may call firmware_upload_register() to expose persistent"loading" and "data" sysfs files. These files are used in the same way asthe fallback sysfs "loading" and "data" files. When 0 is written to"loading" to complete the write of firmware data, the data is transferredto the lower-level driver using pre-registered call-back functions. Thedata transfer is done in the context of a kernel worker thread.Reviewed-by: Luis Chamberlain Reviewed-by: Tianfei zhang Tested-by: Matthew Gerlach Signed-off-by: Russ Weight Link: https://lore.kernel.org/r/20220421212204.36052-5-russell.h.weight@intel.comSigned-off-by: Greg Kroah-Hartman List of files: /linux-6.15/Documentation/ABI/testing/sysfs-class-firmware
