How coreboot passes e820-style system memory map to the OS?
by Darmawan Salihun 25 Mar '10

25 Mar '10

Hi, I wonder how coreboot passes the "e820-style" system memory map to the OS. I found the following data structure pointer in the coreboot source code: static struct parameters *faked_real_mode = (void *)REAL_MODE_DATA_LOC; and also this line: void append_command_line(struct parameters *real_mode, char *arg, int arg_bytes) Does the second line above means "faked_real_mode" is passed as an argument to the bootloader (or probably directly as kernel parameter for Linux)? Or does SeaBIOS perform the necessary e820-style function to OS other than Linux? Thanks, Darmawan -- -------------------------------------------------------------------- -= Human knowledge belongs to the world =-
