2020-03-30linux-user: Support futex_time64Alistair Francis
Add support for host and target futex_time64. If futex_time64 exists on the host we try that first before falling back to the standard futex syscall.

2020-03-26linux-user: Add x86_64 vsyscall page to /proc/self/mapsRichard Henderson
The page isn't (necessarily) present in the host /proc/self/maps, and even if it might be it isn't present in page_flags, and even if it was it might not have the same set of page permissions. The easiest thing to do, particularly when it comes to the "[vsyscall]" note at the end of line, is to special case it.

Previously, the signal handler would be byte swapped if the target and host CPU used different endianness.

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.

2020-02-19linux-user: Add support for getting/setting selected alsa timer parameters ↵Filip Bozuta
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.

This patch implements functionality of following ioctl: SNDRV_TIMER_IOCTL_SELECT - Selecting timer Selects the timer which id is specified. The timer id is specified in the following strcuture: struct snd_timer_select { struct snd_timer_id id; /* timer ID */ unsigned char reserved[32]; /* reserved */ }; A pointer to this structure should be passed as the third ioctl's argument.

2020-02-19linux-user: Add support for getting alsa timer version and idFilip Bozuta
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.

2020-02-19linux-user: Use `qemu_log' for straceJosh Kunz
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.

2020-02-19linux-user: Use `qemu_log' for non-strace loggingJosh Kunz
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.
