* score: Add _IO_Printf() and _IO_Vprintf()Sebastian Huber2017-11-066-206/+463
| | | | | | | | | | | | | | The previous vprintk() implementation had a questionable licence header, lacks support for the 'z' and 'j' format specifiers, is not robust against invalid format specifiers, uses a global variable for output. Replace it with a stripped down version of the FreeBSD kernel kvprintf() function. The new implementation allows a low overhead rtems_snprintf() if necessary. Update #3199. Close #3216.
* posix: Use far future for very long timeoutsSebastian Huber2017-11-023-22/+38
| | | | Close #3205.
* cpukit: RISC-V - make riscv32 code work for riscv64 - v2Hesham Almatary2017-11-0121-49/+72
| | | | | | | | | * Use #ifdefs for 32/64 bit code * Use unsigned long which is 32-bit on riscv32 and 64-bit on riscv64 (register size) * Move the code to a new shared riscv folder to be shared between riscv32 and riscv64 * Rename RTEMS_CPU extracted from command line to shared riscv target s/riscv*/riscv Update #3109

| | | | | | | In case the user provides a stack with address and size, then do not alter the stack size. Close #3211.
* score: Simplify SMP get lowest scheduledSebastian Huber2017-10-283-28/+18
| | | | | | There is no need to pass in the order relation since the scheduled threads reside on an already ordered chain. The caller will decide what to do with the lowest scheduled thread.

| | | | | | | | | | | | The th_bintime, th_microtime and th_nanotime members of the timehand all cache the last system time (uptime + boottime). Only the format differs. Do not re-calculate the bintime and simply use the value used to calculate the microtime and nanotime. Group all the updates under the relevant comment. Remove obsoleted XXX part.

| | | | | | | | | | | | | | | | | | Add missing pieces of r315280 I moved this branch from github to a private server, and pulled from the wrong one when committing r315280, so I failed to include two recent commits. Thankfully, they were only cosmetic and were included in the review. Specifically: Add documentation, polish comments, and improve style(9).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the RTC is adjusted, reevaluate absolute sleep times based on the RTC POSIX 2008 says this about clock_settime(2): If the value of the CLOCK_REALTIME clock is set via clock_settime(), the new value of the clock shall be used to determine the time of expiration for absolute time services based upon the CLOCK_REALTIME clock. This applies to the time at which armed absolute timers expire. If the absolute time requested at the invocation of such a time service is before the new value of the clock, the time service shall expire immediately as if the clock had reached the requested time normally. Setting the value of the CLOCK_REALTIME clock via clock_settime() shall have no effect on threads that are blocked waiting for a relative time service based upon this clock, including the nanosleep() function; nor on the expiration of relative timers based upon this clock. Consequently, these time services shall expire when the requested relative interval elapses, independently of the new or old value of the clock. When the real-time clock is adjusted, such as by clock_settime(3), wake any threads sleeping until an absolute real-clock time. Such a sleep is indicated by a non-zero td_rtcgen. The sleep functions will set that field to zero and return zero to tell the caller to reevaluate its sleep duration based on the new value of the clock. At present, this affects the following functions: pthread_cond_timedwait(3) pthread_mutex_timedlock(3) pthread_rwlock_timedrdlock(3) pthread_rwlock_timedwrlock(3) sem_timedwait(3) sem_clockwait_np(3) I'm working on adding clock_nanosleep(2), which will also be affected.

| | | | | | | | | | | | | | | | | | | | | | Add labels to sysctls related to clocks. Sysctls like kern.eventtimer.et.*.quality currently embed the name of the clock device. This is problematic for the Prometheus metrics exporter for two reasons: - Some of those clocks have dashes in their names, which Prometheus doesn't allow to be used in metric names. - It doesn't allow for extracting the same property of all clocks on the system from within a single query. Attach these nodes to have a label, so that the Prometheus metrics exporter gives these metric a uniform name with the name of the clock attached as a label.
