From 81eb1a369da5f9cb282b65f1221899cc07711df2 Mon Sep 17 00:00:00 2001 From: Aleksandar Markovic Date: Thu, 16 Jan 2020 23:49:46 +0100 Subject: [PATCH] linux-user: Add support for FD ioctls FDSETEMSGTRESH, FDSETMAXERRS, and FDGETMAXERRS ioctls are commands for controlling error reporting of a floppy drive. FDSETEMSGTRESH's third agrument is a pointer to the structure: struct floppy_max_errors { unsigned int abort, /* number of errors to be reached before aborting */ read_track, /* maximal number of errors permitted to read an * entire track at once */ reset, /* maximal number of errors before a reset is tried */ recal, /* maximal number of errors before a recalibrate is * tried */ /* * Threshold for reporting FDC errors to the console. * Setting this to zero may flood your screen when using * ultra cheap floppies ;-) */ reporting; }; defined in Linux kernel header . Since all fields of the structure are of type 'unsigned int', there is no need to define "target_floppy_max_errors". FDSETMAXERRS and FDGETMAXERRS ioctls do not use the third argument.
