Driver probe routine allocates structure to communicate status and parameters between functions in the driver. Also call load_ifs_binary() to load the scan image file. There is a separate scan image file for each processor family, model, stepping combination. This is read from the static path: /lib/firmware/intel/ifs/{ff-mm-ss}.scan Step 1 in loading is to generate the correct path and use request_firmware_direct() to load into memory. Subsequent patches will use the IFS MSR interfaces to copy the image to BIOS reserved memory and validate the SHA256 checksums.
