Filip Bozuta 045823a98c linux-user: Add support for selected alsa timer instructions using ioctls
This patch implements functionalities of following ioctls:

SNDRV_TIMER_IOCTL_START - Start selected alsa timer

    Starts the timer device that is selected. The third ioctl's argument is
    ignored. Before calling this ioctl, the ioctl "SNDRV_TIMER_IOCTL_SELECT"
    should be called first to select the timer that is to be started. If no
    timer is selected, the error EBADFD ("File descriptor in bad shape")
    is returned.

SNDRV_TIMER_IOCTL_STOP - Stop selected alsa timer

    Stops the timer device that is selected. The third ioctl's argument is
    ignored. Before calling this ioctl, the ioctl "SNDRV_TIMER_IOCTL_SELECT"
    should be called first to select the timer that is to be stopped. If no
    timer is selected, the error EBADFD ("File descriptor in bad shape")
    is returned.

SNDRV_TIMER_IOCTL_CONTINUE - Continue selected alsa timer

    Continues the timer device that is selected. The third ioctl's argument is
    ignored. Before calling this ioctl, the ioctl "SNDRV_TIMER_IOCTL_SELECT"
    should be called first to select the timer that is to be continued. If no
    timer is selected, the error EBADFD ("File descriptor in bad shape")
    is returned.

SNDRV_TIMER_IOCTL_PAUSE - Pause selected alsa timer

    Pauses the timer device that is selected. The third ioctl's argument is
    ignored. Before calling this ioctl, the ioctl "SNDRV_TIMER_IOCTL_SELECT"
    should be called first to select the timer that is to be paused. If no
    timer is selected, the error EBADFD ("File descriptor in bad shape")
    is returned.

Implementation notes:

    Since all of the implemented ioctls have NULL as their third argument,
    their implementation was straightforward.

Filip Bozuta fe333025c6 linux-user: Add support for getting/setting selected alsa timer parameters using ioctls
This patch implements functionalities of following ioctls:

SNDRV_TIMER_IOCTL_INFO - Getting information about selected timer

    Read information about the selected timer. The information is returned in
    the following structure:

    struct snd_timer_info {
        unsigned int flags;         /* timer flags - SNDRV_TIMER_FLG_* */
        int card;                   /* card number */
        unsigned char id[64];       /* timer identificator */
        unsigned char name[80];     /* timer name */
        unsigned long reserved0;    /* reserved for future use */
        unsigned long resolution;   /* average period resolution in ns */
        unsigned char reserved[64]; /* reserved for future use */
    };

    A pointer to this structure should be passed as the third ioctl's argument.
    Before calling this ioctl, the ioctl "SNDRV_TIMER_IOCTL_SELECT" should be
    called first to select the timer which information is to be obtained. If no
    timer is selected, the error EBADFD ("File descriptor in bad shape") is
    returned.

SNDRV_TIMER_IOCTL_PARAMS - Setting parameters for selected timer

    Sets parameters for the selected timer. The paramaters are set in the
    following structure:

    struct snd_timer_params {
        unsigned int flags;         /* flags - SNDRV_TIMER_PSFLG_* */
        unsigned int ticks;         /* requested resolution in ticks */
        unsigned int queue_size;    /* total size of queue (32-1024) */
        unsigned int reserved0;     /* reserved, was: failure locations */
        unsigned int filter;        /* event filter */
        unsigned char reserved[60]; /* reserved */
    };

    A pointer to this structure should be passed as the third ioctl's argument.
    Before calling this ioctl, the ioctl "SNDRV_TIMER_IOCTL_SELECT" should be
    called first to select the timer which parameters are to be set. If no
    timer is selected, the error EBADFD ("File descriptor in bad shape") is
    returned.

SNDRV_TIMER_IOCTL_STATUS - Getting status of selected timer

    Read status of the selected timer. The status of the timer is returned in
    the following structure:

    struct snd_timer_status {
        struct timespec tstamp;     /* Timestamp - last update */
        unsigned int resolution;    /* current period resolution in ns */
        unsigned int lost;          /* counter of master tick lost */
        unsigned int overrun;       /* count of read queue overruns */
        unsigned int queue;         /* used queue size */
        unsigned char reserved[64]; /* reserved */
    };

    A pointer to this structure should be passed as the third ioctl's argument.
    Before calling this ioctl, the ioctl "SNDRV_TIMER_IOCTL_SELECT" should be
    called first to select the timer which status is to be obtained. If no
    timer is selected, the error EBADFD ("File descriptor in bad shape") is
    returned.

Implementation notes:

    All ioctls in this patch have pointer to some kind of a structure
    as their third argument. That is the reason why corresponding
    definitions were added in 'linux-user/syscall_types.h'. Structure
    'snd_timer_status' has field of type 'struct timespec' which is why
    a corresponding definition of that structure was also added in
    'linux-user/syscall_types.h'. All of these strucutures have some
    fields that are of type 'unsigned long'. That is the reason why
    separate target structures were defined in 'linux-user/syscall_defs.h'.
    Structure 'struct timespec' already had a separate target definition
    so that definition was used to define a target structure for
    'snd_timer_status'. The rest of the implementation was straightforward.

    A pointer to this structure should be passed as the third ioctl's argument.
    Before calling the ioctl, the field "tid" should be initialized with the id
    information for the timer which information is to be obtained. After the
    ioctl call, the rest of the structure fields are filled with values from
    the timer device with the specified id. If there is no device with the
    specified id, the error ENODEV ("No such device") is returned.

SNDRV_TIMER_IOCTL_GPARAMS - Setting precise period duration

    Sets timer precise period duration numerator and denominator in seconds. The
    period duration is set in the following structure:

        struct snd_timer_gparams {
            struct snd_timer_id tid;    /* requested timer ID */
            unsigned long period_num;   /* period duration - numerator */
            unsigned long period_den;   /* period duration - denominator */
            unsigned char reserved[32]; /* reserved */
        };

    A pointer to this structure should be passed as the third ioctl's argument.
    Before calling the ioctl, the field "tid" should be initialized with the id
    information for the timer which period duration is to be set. Also, the
    fileds "period_num" and "period_den" should be filled with the period
    duration numerator and denominator values that are to be set respectively.
    If there is no device with the specified id, the error ENODEV ("No such
    device") is returned.

SNDRV_TIMER_IOCTL_GSTATUS - Getting current period resolution

    Read timer current period resolution in nanoseconds and period resolution
    numerator and denominator in seconds. The period resolution information is
    returned in the following structure:

    struct snd_timer_gstatus {
        struct snd_timer_id tid;        /* requested timer ID */
        unsigned long resolution;       /* current period resolution in ns */
        unsigned long resolution_num;   /* period resolution - numerator */
        unsigned long resolution_den;   /* period resolution - denominator */
        unsigned char reserved[32];     /* reserved for future use */
    };

    A pointer to this structure should be passed as the third ioctl's argument.
    Before calling the ioctl, the field "tid" should be initialized with the id
    information for the timer which period resolution is to be obtained. After
    the ioctl call, the rest of the structure fields are filled with values
    from the timer device with the specified id. If there is no device with the
    specified id, the error ENODEV ("No such device") is returned.

Filip Bozuta 1c4c6fcd1a linux-user: Add support for getting alsa timer version and id
This patch implements functionalities of following ioctls:

SNDRV_TIMER_IOCTL_PVERSION - Getting the sound timer version

    Read the sound timer version. The third ioctl's argument is
    a pointer to an int in which the specified timers version
    is returned.

SNDRV_TIMER_IOCTL_NEXT_DEVICE - Getting id information about next timer

    Read id information about the next timer device from the sound timer
    device list. The id infomration is returned in the following structure:

        struct snd_timer_id {
            int dev_class;    /* timer device class number */
            int dev_sclass;   /* slave device class number (unused) */
            int card;         /* card number */
            int device;       /* device number */
            int subdevice;    /* sub-device number */
        };

    The devices in the sound timer device list are arranged by the fields
    of this structure respectively (first by dev_class number, then by
    card number, ...). A pointer to this structure should be passed as
    the third ioctl's argument. Before calling the ioctl, the parameters
    of this structure should be initialized in relation to the next timer
    device which information is to be obtained. For example, if a wanted
    timer device has the device class number equal to or bigger then 2,
    the field dev_class should be initialized to 2. After the ioctl call,
    the structure fields are filled with values from the next device in
    the sound timer device list. If there is no next device in the list,
    the structure is filled with "zero" id values (in that case all
    fields are filled with value -1).

Implementation notes:

    The ioctl 'SNDRV_TIMER_IOCTL_NEXT_DEVICE' has a pointer to a
    'struct snd_timer_id' as its 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 was straightforward.

    The line '#include <linux/rtc.h>' was added to recognize
    preprocessor definitions for these ioctls. This needs to be
    done only once in this series of commits. Also, the content
    of this file (with respect to ioctl definitions) remained
    unchanged for a long time, therefore there is no need to
    worry about supporting older Linux kernel version.

Josh Kunz 4b25a50674 linux-user: Use `qemu_log' for strace
This change switches linux-user strace logging to use the newer `qemu_log`
logging subsystem rather than the older `gemu_log` (notice the "g")
logger. `qemu_log` has several advantages, namely that it allows logging
to a file, and provides a more unified interface for configuration
of logging (via the QEMU_LOG environment variable or options).

This change introduces a new log mask: `LOG_STRACE` which is used for
logging of user-mode strace messages.

Josh Kunz 39be535008 linux-user: Use `qemu_log' for non-strace logging
Since most calls to `gemu_log` are actually logging unimplemented features,
this change replaces most non-strace calls to `gemu_log` with calls to
`qemu_log_mask(LOG_UNIMP, ...)`.  This allows the user to easily log to
a file, and to mask out these log messages if they desire.

Note: This change is slightly backwards incompatible, since now these
"unimplemented" log messages will not be logged by default.

Philippe Mathieu-Daudé e10ee3f567 configure: Avoid compiling system tools on user build by default
User-mode does not need the system tools. Do not build them by
default if the user specifies --disable-system.

This disables building the following binaries on a user-only build:

- elf2dmp
- qemu-edid
- qemu-ga
- qemu-img
- qemu-io
- qemu-nbd
- ivshmem-client
- ivshmem-server

The qemu-user binaries are not affected by this change.

if softmmu is not enabled, we disable by default fdt and

A side effect is the git submodules are not cloned

Clone and build can be forced with --enable-fdt and
--enable-slirp.

Indeed the array should contain 13 entries, the undocumented
register 0x82c is missing. Fix by increasing the array size
and adding the missing register.
