This patch implements functionalities of following ioctls:
RTC_PLL_GET - Getting PLL correction
Read the PLL correction for RTCs that support PLL. The PLL correction
is returned in the following structure:
struct rtc_pll_info {
int pll_ctrl; /* placeholder for fancier control */
int pll_value; /* get/set correction value */
int pll_max; /* max +ve (faster) adjustment value */
int pll_min; /* max -ve (slower) adjustment value */
int pll_posmult; /* factor for +ve correction */
int pll_negmult; /* factor for -ve correction */
long pll_clock; /* base PLL frequency */
};
A pointer to this structure should be passed as the third
ioctl's argument.
RTC_PLL_SET - Setting PLL correction
Sets the PLL correction for RTCs that support PLL. The PLL correction
that is set is specified by the rtc_pll_info structure pointed to by
the third ioctl's' argument.
Implementation notes:
All ioctls in this patch have a pointer to a structure rtc_pll_info
as their third argument. All elements of this structure are of
type 'int', except the last one that is of type 'long'. That is
the reason why a separate target structure (target_rtc_pll_info)
is defined in linux-user/syscall_defs. The rest of the
implementation is straightforward.

This patch implements functionalities of following ioctls:
RTC_WKALM_SET, RTC_WKALM_GET - Getting/Setting wakeup alarm
Some RTCs support a more powerful alarm interface, using these
ioctls to read or write the RTC's alarm time (respectively)
with this structure:
struct rtc_wkalrm {
unsigned char enabled;
unsigned char pending;
struct rtc_time time;
};
The enabled flag is used to enable or disable the alarm
interrupt, or to read its current status; when using these
calls, RTC_AIE_ON and RTC_AIE_OFF are not used. The pending
flag is used by RTC_WKALM_RD to report a pending interrupt
(so it's mostly useless on Linux, except when talking to the
RTC managed by EFI firmware). The time field is as used with
RTC_ALM_READ and RTC_ALM_SET except that the tm_mday, tm_mon,
and tm_year fields are also valid. A pointer to this structure
should be passed as the third ioctl's argument.
Implementation notes:
All ioctls in this patch have a pointer to a structure
rtc_wkalrm as their third argument. That is the reason why
corresponding definition is added in linux-user/syscall_types.h.
Since all elements of this structure are either of type
'unsigned char' or 'struct rtc_time' (that was covered in one
of previous patches), the rest of the implementation is
straightforward.

This patch implements functionalities of following ioctls:
RTC_RD_TIME - Getting RTC time
Returns this RTC's time in the following structure:
struct rtc_time {
int tm_sec;
int tm_min;
int tm_hour;
int tm_mday;
int tm_mon;
int tm_year;
int tm_wday; /* unused */
int tm_yday; /* unused */
int tm_isdst; /* unused */
};
The fields in this structure have the same meaning and ranges
as the tm structure described in gmtime man page. A pointer
to this structure should be passed as the third ioctl's argument.
RTC_SET_TIME - Setting RTC time
Sets this RTC's time to the time specified by the rtc_time
structure pointed to by the third ioctl's argument. To set
the RTC's time the process must be privileged (i.e., have the
CAP_SYS_TIME capability).
RTC_ALM_READ, RTC_ALM_SET - Getting/Setting alarm time
Read and set the alarm time, for RTCs that support alarms.
The alarm interrupt must be separately enabled or disabled
using the RTC_AIE_ON, RTC_AIE_OFF requests. The third
ioctl's argument is a pointer to a rtc_time structure. Only
the tm_sec, tm_min, and tm_hour fields of this structure are
used.
Implementation notes:
All ioctls in this patch have pointer to a structure rtc_time
as their third argument. That is the reason why corresponding
definition is added in linux-user/syscall_types.h. Since all
elements of this structure are of type 'int', the rest of the
implementation is straightforward.

FDFMTBEG, FDFMTTRK, and FDFMTEND ioctls provide means for controlling
formatting of a floppy drive.
FDFMTTRK's third agrument is a pointer to the structure:
struct format_descr {
unsigned int device,head,track;
};
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_format_descr".
FDFMTBEG and FDFMTEND ioctls do not use the third argument.

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 */

/*
* Threshold for reporting FDC errors to the console.
* Setting this to zero may flood your screen when using
* ultra cheap floppies ;-)
*/

};
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.

The SIOCGSTAMP symbol was previously defined in the
asm-generic/sockios.h header file. QEMU sees that header
indirectly via sys/socket.h
In linux kernel commit 0768e17073dc527ccd18ed5f96ce85f9985e9115
the asm-generic/sockios.h header no longer defines SIOCGSTAMP.
Instead it provides only SIOCGSTAMP_OLD, which only uses a
32-bit time_t on 32-bit architectures.
The linux/sockios.h header then defines SIOCGSTAMP using
either SIOCGSTAMP_OLD or SIOCGSTAMP_NEW as appropriate. If
SIOCGSTAMP_NEW is used, then the tv_sec field is 64-bit even
on 32-bit architectures
To cope with this we must now convert the old and new type from
the target to the host one.

The LOOP_GET_STATUS and LOOP_GET_STATUS64 ioctls were incorrectly
defined as IOC_W rather than IOC_R, which meant we weren't
correctly copying the information back from the kernel to the guest.
The loop_info64 structure definition was also missing a member
and using the wrong type for several 32-bit fields.
In particular, this meant that "kpartx -d image.img" didn't work
and "losetup -a" behaved strangely. Correct the ioctl type definitions.
