linux-user: Add support for FD<SETEMSGTRESH|SETMAXERRS|GETMAXERRS> 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 <linux/fd.h>.
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.
