nickg — Mon, 08 Jan 2007 16:20:13 +0000

* src/sched/mlqueue.cxx (add_thread, yield):
* src/sched/sched.cxx (unlock_inner, thread_entry):
* 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.

* src/sync/mbox.cxx (Cyg_Mbox::get): Fix compiler warning with gcc

nickg — Thu, 12 Oct 2006 15:41:49 +0000

* cdl/synch.cdl: Added CYGIMP_MBOX_USE_MBOXT_PLAIN option. This is
tested in various places but was not actually defined. It now is
and defaults to 1 so that the plain version of mail boxes is
selected.

* include/mboxt.inl:
* include/mboxt2.inl: Moved various CYG_ASSERTCLASS() calls to be
within scheduler locked regions. Race conditions could have caused
them to fail before.

* tests/mbox1.cxx:
* tests/kmbox1.cxx: Updated tests to work with mboxt
implementation. This requires thread 1 to run at lower priority
than thread 0.

* doc/kernel.sgml: Use reinterpret_cast, not static cast

jlarmour — Mon, 21 Aug 2006 17:13:45 +0000

compile on targets wit h only small amounts of RAM.

the amount of RAM in small systems.
* tests/clocktruth.cxx: Fix the header.

* src/sched/sched.cxx (thread_entry): Fixed a bug which could

nickg — Thu, 19 Jan 2006 17:53:58 +0000

* src/sched/sched.cxx (thread_entry): Fixed a bug which could
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.

* src/sched/sched.cxx:

nickg — Tue, 10 Jan 2006 15:52:54 +0000

* 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.

asl — Wed, 23 Nov 2005 20:58:28 +0000

implementation which the compiler wants to inline.

sched.inl right before it to solve mutual header dependency
problems.

nickg — Mon, 13 Oct 2003 17:20:18 +0000

* src/common/clock.cxx (Cyg_Counter::tick): Changed code to deal
with manipulation of unsorted lists (see ChangeLogs passim). There
are several corner cases where the current code does not
work. Replaced with a more straightforward, but slightly more
expensive, implementation.

nickg — Thu, 24 Jul 2003 20:27:28 +0000

* cdl/counters.cdl: Removed the counters override CDL
options. These are no longer very useful, since too much
non-kernel code now uses the HAL options to get these values.

nickg — Thu, 10 Jul 2003 17:41:07 +0000

* src/common/clock.cxx (Cyg_Counter::tick): In unsorted list case:
moved saving of next node details to before re-insertion of alarms
with intervals. The call to add_alarm() can make enough of a
difference to the list to need to force a rescan.
