* include/mlqueue.hxx (class Cyg_SchedThread_Implementation):
* include/kapidata.h (CYG_SCHEDTHREAD_TIMESLICE_MEMBER):
* include/bitmap.hxx (class Cyg_SchedThread_Implementation):
Reimplement timeslicing code. There is now a timeslice_count field
in each thread which is moved to and from the per-CPU counter
during thread dispatch. This approach has been taken to minimize
the changes needed to SMP code. Scheduler specific thread
functions handle counter save, restore and reset. These functions
are defined (as empty inlines) even when timeslicing is disabled,
or in non-timeslicing schedulers, to avoid adding ifdefs to the
code (this change actually removes some).

* tests/timeslice2.c:
* cdl/kernel.cdl: Added timeslice2 test to test behaviour of
timeslicing while being preempted.]]> nickg Mon, 08 Jan 2007 16:20:13 +0000 https://hg.ecoscentric.com/ecos/log/1406c9fadbf3/packages/kernel/current/src/sched/sched.cxx cause a thread to be started with a non-zero scheduler lock. The
previous code only decremented it by 1 so if the previous thread
was executing with the lock > 1 the thread ended up with a
non-zero lock. This is fixed by decrementing the lock in a loop
until it reaches zero.

* src/common/thread.cxx (idle_thread_main): Added an assert for a
non-zero scheduler lock.]]> nickg Thu, 19 Jan 2006 17:53:58 +0000 https://hg.ecoscentric.com/ecos/log/5d7f57fd1729/packages/kernel/current/src/sched/sched.cxx * include/sched.hxx (class Cyg_Scheduler): Added thread_entry()
member function. This handles thread startup housekeeping. Zeroing
the scheduler lock is handled by calling unlock() so that DSRs may
be run.

* src/common/thread.cxx (thread_entry): Refactored code to call
Cyg_Scheduler::thread_entry() instead of doing all the work here.]]> nickg Tue, 10 Jan 2006 15:52:54 +0000 https://hg.ecoscentric.com/ecos/log/a29ee6c2dd3c/packages/kernel/current/src/sched/sched.cxx assertion. This has served its purpose and with the introduction
of routines such as unlock_reschedule() is prone to firing in
otherwise benign circumstances.]]> nickg Fri, 09 Aug 2002 17:13:28 +0000 https://hg.ecoscentric.com/ecos/log/d2c90368aeef/packages/kernel/current/src/sched/sched.cxx jlarmour Thu, 23 May 2002 22:59:51 +0000 https://hg.ecoscentric.com/ecos/log/e0c0827131d1/packages/kernel/current/src/sched/sched.cxx jlarmour Mon, 20 May 2002 22:19:26 +0000 https://hg.ecoscentric.com/ecos/log/4c750ce71ae3/packages/kernel/current/src/sched/sched.cxx jlarmour Fri, 10 Aug 2001 19:27:55 +0000 https://hg.ecoscentric.com/ecos/log/42f843b391aa/packages/kernel/current/src/sched/sched.cxx jlarmour Wed, 18 Jul 2001 11:38:39 +0000 https://hg.ecoscentric.com/ecos/log/6b5f480c6929/packages/kernel/current/src/sched/sched.cxx jlarmour Fri, 08 Dec 2000 03:30:06 +0000 https://hg.ecoscentric.com/ecos/log/eb9fd8c04db3/packages/kernel/current/src/sched/sched.cxx jlarmour Mon, 23 Oct 2000 17:10:57 +0000 https://hg.ecoscentric.com/ecos/log/0c2b7be0d798/packages/kernel/current/src/sched/sched.cxx jlarmour Thu, 12 Oct 2000 20:31:43 +0000 https://hg.ecoscentric.com/ecos/log/0ec04793409a/packages/kernel/current/src/sched/sched.cxx jlarmour Mon, 11 Sep 2000 02:42:46 +0000 https://hg.ecoscentric.com/ecos/log/6ed91473a1cd/packages/kernel/current/src/sched/sched.cxx jlarmour Fri, 25 Aug 2000 17:32:38 +0000 https://hg.ecoscentric.com/ecos/log/59d97b6ba612/packages/kernel/current/src/sched/sched.cxx jlarmour Tue, 28 Mar 2000 20:13:29 +0000 https://hg.ecoscentric.com/ecos/log/bf00f99aec69/packages/kernel/current/src/sched/sched.cxx jlarmour Wed, 02 Feb 2000 19:57:02 +0000 https://hg.ecoscentric.com/ecos/log/c38311975d4f/packages/kernel/current/src/sched/sched.cxx jlarmour Fri, 28 Jan 2000 04:59:39 +0000 https://hg.ecoscentric.com/ecos/log/7a6ac9edc838/packages/kernel/current/src/sched/sched.cxx jlarmour Mon, 24 Jan 2000 21:43:17 +0000 https://hg.ecoscentric.com/ecos/log/443894e2e912/packages/kernel/current/src/sched/sched.cxx jlarmour Tue, 11 May 1999 12:24:34 +0000 https://hg.ecoscentric.com/ecos/log/3111d98ba7b3/packages/kernel/current/src/sched/sched.cxx jlarmour Tue, 11 May 1999 11:16:07 +0000
