RTLinux/Open 3.2 is now available from: ftp://ftp.rtlinux.com/pub/rtlinux/v3/New in 3.2 * sem_getvalue() fixed (thanks to David Hamilton <David.Hamilton@jet.uk>) * updated documentation * simplified remote debuggingOld announcements:RTLinux/Open 3.1 is now available from: ftp://ftp.rtlinux.com/pub/rtlinux/v3/New in 3.1 * Both v2.4.4 and v2.2.19 kernels are supported * RTLinux modules are compiled correctly when module versioning is enabled * POSIX support fixes and enhancements * RT-threads can be created from other RT-threads with preallocated memory * Compatibility mode fixes (rt_get_time and others) * CLOCK_GPOS is a new POSIX clock that converges to the Linux system clock * The interrupt focus feature is also supported with 2.2.x kernels * CLOCK_REALTIME is now the same as CLOCK_RTL_SCHED * The new rtl_posixio RTF_SETSIZE ioctl can be used to change the fifo sizeNote on POSIX clocks. There are 3 clocks available to the RTLinux programs:- CLOCK_MONOTONIC. This essentially a scaled CPU cycle counter. It expressestime passed since system bootup. The main use - CLOCK_REALTIME. This is the clock used for thread scheduling. sem_timedwait,nanosleep, pthread_make_periodic_np and others use time values relative tothis clock. In oneshot (default) mode, time shown by this clock is the sameas that of CLOCK_MONOTONIC. In periodic mode, CLOCK_REALTIME becomes localto the CPU.- CLOCK_GPOS. This clock always converges to the Linux system clock and thusis subject to ntpd adjustments etc.
