2019-06-24Cygwin: Implement sched_[gs]etaffinity()Mark Geisert
This patch set implements the Linux syscalls sched_getaffinity, sched_setaffinity, pthread_getaffinity_np, and pthread_setaffinity_np. Linux has a straightforward view of the cpu sets used in affinity masks. They are simply long (1024-bit) bit masks. This code emulates that view while internally dealing with Windows' distribution of available CPUs among processor groups.
2019-03-01Cygwin: fenv.h: Add feature test macros, fix valuesCorinna Vinschen
- feenableexcept,fedisableexcept, fegetexcept are GNU-only - fegetprec, fesetprec are Solaris, use __MISC_VISIBLE - _feinitialise is Cygwin-internal only - Replace self-named FP precision values to values from http://www.open-std.org/jtc1/sc22//WG14/www/docs/n752.htm as used by Solaris. - Change return value of fesetprec to adhere to the above document and Solaris. - Document fegetprec, fesetprec as Solaris functions, not as GNU functions Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

2019-01-16Cygwin: timers: implement timerfdCorinna Vinschen
First cut of a timerfd implementation. Still TODO: - fork/exec semantics - timerfd_settime TFD_TIMER_CANCEL_ON_SET flag - ioctl(TFD_IOC_SET_TICKS) - bug fixes Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
2019-01-14Cygwin: signal: implement signalfdCorinna Vinschen
First cut of a signalfd implementation. Still TODO: Non-polling select. This should mostly work as on Linux except for missing support for some members of struct signalfd_siginfo, namely ssi_fd, ssi_band (both SIGIO/SIGPOLL, not fully implemented) and ssi_trapno (HW exception, required HW support).

2018-07-25POSIX Asynchronous I/O support: other filesMark Geisert
Updates to misc files to integrate AIO into the Cygwin source tree. Much of it has to be done when adding any new syscalls. There are some updates to limits.h for AIO-specific limits. And some doc mods.

2017-06-14Export XSI sigpauseYaakov Selkowitz
There are two common sigpause variants, both of which take an int argument. If you request _XOPEN_SOURCE or _GNU_SOURCE, you get the System V version, which removes the given signal from the process's signal mask; otherwise you get the BSD version, which sets the process's signal mask to the given value.

2016-08-23Add pthread_getname_np and pthread_setname_npJon Turney
This patch adds pthread_getname_np and pthread_setname_np. These were added to glibc in 2.12[1] and are also present in some form on NetBSD and several UNIXes. The code is based on NetBSD's implementation with changes to better match Linux behaviour. Implementation quirks: * pthread_setname_np with a NULL pointer segfaults (as linux) * pthread_setname_np returns ERANGE for names longer than 16 characters (as linux) * pthread_getname_np with a NULL pointer returns EFAULT (as linux) * pthread_getname_np with a buffer length of less than 16 returns ERANGE (as linux) * pthread_getname_np truncates the thread name to fit the buffer length. This guarantees success even when the default thread name is longer than 16 characters, but means there is no way to discover the actual length of the thread name. (Linux always truncates the thread name to 16 characters) * Changing program_invocation_short_name changes the default thread name (on linux, it has no effect on the default thread name) I'll leave it up to you to decide if any of these matter. This is implemented via class pthread_attr to make it easier to add pthread_attr_[gs]etname_np (present in NetBSD and some UNIXes) should it ever be added to Linux (or we decide we want it anyway).
