* compiler-gcc*.h: Keep on the gcc 5 version for nowSamuel Thibault2019-09-065-268/+4

* Add GPLv3 license textKalle Olavi Niemitalo2018-11-261-0/+674
| | | | | | | | | | | To help people satisfy the license when they convey clones of the gnumach Git repository, in which gitlog-to-changelog and some deleted files are licensed under GPLv3-or-later. A normal build does not use the GPLv3-or-later files. "make dist" runs gitlog-to-changelog but does not copy it to gnumach-*.tar. Bug: https://savannah.gnu.org/bugs/?49024
* Fix interactivity of inactive threadsSamuel Thibault2018-11-191-0/+11
| | | | | | | | | | | A new thread will mosty probably start working, assume it will take its share of CPU, to avoid having to find it out slowly. Decaying will however fix that quickly if it actually does not work. This fixes stalling issues when a program keeps creating threads. * kern/thread.c (thread_create): Set new_thread's cpu_usage and sched_usage to a fair share of the current load.
* Fix task and thread collection frequencySamuel Thibault2018-11-192-2/+4
| | | | | | | | | sched_tick is incremented only once per second, not once per tick. * kern/task.c (consider_task_collect): Divide task_collect_max_rate by (hz / 1) to get a number of scheduler ticks. * kern/thread.c (consider_thread_collect): Divide thread_collect_max_rate by (hz / 1) to get a number of scheduler ticks.

| | | | | | | | | | | | | This wasn't building and is not useful with nowaday's hardware. * configfrag.ac (SIMPLE_CLOCK): Do not define. * kern/sched.h [SIMPLE_CLOCK] (sched_usec): Remove variable declaration. * kern/sched_prim.c [SIMPLE_CLOCK] (sched_usec): Remove variable. [SIMPLE_CLOCK] (sched_init): Do not initialize sched_usec variable. [SIMPLE_CLOCK] (recompute_priorities): Do not tinker sched_usec variable. * kern/thread.c [SIMPLE_CLOCK] (thread_info): Do not ajust for clock drift.
* Make scheduling more reactiveSamuel Thibault2018-11-192-1/+2
| | | | | | | | Give smaller quantums to processes, to get more frequent context switches. This fixes some reactivity for concurrent processes. * kern/sched.h (MIN_QUANTUM): Define to hz / 33. * kern/sched_prim.c (sched_init): Use MIN_QUANTUM instead of hz / 10.
* build: Distribute tarball compressed with xz instead of bzip2Guillem Jover2018-11-061-1/+1
| | | | * configure.ac (AM_INIT_AUTOMAKE): Change dist-bzip2 to dist-xz.
* Fix using all dynamic prioritiesSamuel Thibault2018-11-042-5/+5
| | | | | | | | | | | 6a2342010811 ("Increase number of priorities") increased NRQS but didn't increase PRI_SHIFT to extend the use of the additional queues by the scheduler. This does it. While at it, extend to NRQS to 64, the double of the original 32, to keep all values coherent. * i386/i386/sched_param.h (PRI_SHIFT): Set from 18 to 17. * kern/sched.h (PRI_SHIFT): Set from 18 to 17. (NRQS): Set to 64.
