2000-09-08  Nick Garnett  <nickg@cygnus.co.uk>

	* include/sched.hxx:
	* include/sched.inl:
	Added Cyg_Scheduler::unlock_reschedule() function. This decrements
	the scheduler lock by one but also permits the current thread to
	be rescheduled if it ready to sleep, or there is a higher priority
	thread ready to run. This is to support use of various
	synchronization objects while the scheduler lock is claimed.

	* src/sched/sched.cxx (unlock_inner): Modified precondition to
	allow for functionality of unlock_reschedule().

	* src/sched/mlqueue.cxx:
	Now uses Cyg_SchedulerThreadQueue_Implementation for all runqueue
	pointers. It was using Cyg_ThreadQueue_Implementation in some
	places which meant we were trying to sort the run queues!
	Changed yield() so it can be called with the scheduler lock
	claimed.
	Changed Cyg_Scheduler_Implementation::timeslice() to rotate the
	queue itself rather than call yield(). The changes to yield() make
	it unsafe to call here any more.

	* include/mlqueue.hxx (class Cyg_SchedulerThreadQueue_Implementation): 
	Made enqueue() member public.
	
	* include/mboxt2.inl:
	* src/common/thread.cxx: 
	* src/sync/mutex.cxx: 
	* src/sync/cnt_sem2.cxx: 
	Removed assertions for zero scheduler lock and replaced some
	invocations of Cyg_Scheduler::unlock() with
	Cyg_Scheduler::unlock_reschedule() or Cyg_Scheduler::reschedule()
	where appropriate.

	* tests/klock.c:
	* cdl/kernel.cdl:
	Added klock.c to test functionality while scheduler lock is claimed.

2000-08-17  Hugo Tyson  <hmt@cygnus.co.uk>

	* src/sched/sched.cxx (unlock_inner): Move an assert to some place
	where it's true *all* the time!  There was a narrow margin where a
	DSR could confuse unlock_inner() by reanimating the current thread
	before it had a chance to sleep - hence the call appears to be
	pointless.  Putting the assert before the DSR calls makes sense.

	* include/mboxt.inl:
	* src/sync/bin_sem.cxx:
	* src/sync/cnt_sem.cxx:
	* src/sync/flag.cxx:
	* src/sync/mutex.cxx:
	All of these now use Cyg_Scheduler::reschedule() rather than an
	unlock/lock pair to yield in their functions which can sleep.
	They therefore can be called safely and atomically with the
	scheduler already locked.  This is a Good Thing[tm].  Since the
	network stack synch primitives now use this feature, the asserts
	that the scheduler was not locked must disappear: this change.


2000-08-07  Jonathan Larmour  <jlarmour@redhat.co.uk>

	* include/mutex.hxx (class Cyg_Mutex): Add comment explaining
	presence of locked.

2000-08-04  Jonathan Larmour  <jlarmour@redhat.co.uk>

	* tests/stress_threads.c (STACK_SIZE_HANDLER): Increase stack sizes
	otherwise it crashes!

2000-07-31  Jonathan Larmour  <jlarmour@redhat.co.uk>

	* include/mempolt2.hxx: As per change of 2000-07-04, also delete - left
	behind accidentally

2000-07-20  Nick Garnett  <nickg@cygnus.co.uk>

	* include/mutex.hxx (class Cyg_Mutex): Added get_ceiling()
	accessor function.

	* src/sched/mlqueue.cxx: Fixed bug in sorted queue code that
	resulted in an infinite loop if the thread being inserted is of
	lower priority than all threads in the queue. This case is now
	detected early.

2000-07-17  Gary Thomas  <gthomas@redhat.com>

	* tests/kflag1.c (FIRST_THREAD_WAIT_TIME): Parameterize thread 
	synchronization wait times (for understanding) and adjust for
	incredibly slow platforms.  [Previous value allowed for the test
	to get out of sync because the code ran so slowly]

2000-07-04  Jonathan Larmour  <jlarmour@redhat.co.uk>

	* cdl/kernel.cdl: Remove all configury related to memory allocators,
	including tests. Make CYGFUN_KERNEL_API_C require CYGFUN_MEMALLOC_KAPI

	* include/memfixed.hxx, include/mempolt2.inl, include/mempoolt.hxx,
	  include/mempoolt.inl, include/memvar.hxx, include/mfiximpl.hxx,
	  include/mfiximpl.inl, include/mvarimpl.hxx, include/mvarimpl.inl, 
	  src/mem/memfixed.cxx, src/mem/memvar.cxx, tests/kmemfix1.c,
	  tests/kmemvar1.c, tests/memfix1.cxx, tests/memfix2.cxx,
	  tests/memvar1.cxx, tests/memvar2.cxx:
	Move to separate memory allocator package CYGPKG_MEMALLOC
	
	* include/kapi.h, include/kapidata.h, src/common/kapi.cxx:
	Remove memory allocator functionality - now implemented in
	CYGPKG_MEMALLOC

	* tests/dhrystone.c:
	Update configuration dependencies for new isoinfra design
	* tests/stress_threads.c:
	Likewise.
	Also fix early termination after DEATH_TIME_LIMIT so that 
	allocated resources are freed, and so more appropriate
	statistics are reported
	Also update to use mallinfo() interface to memory allocator

2000-06-23  Hugo Tyson  <hmt@cygnus.co.uk>

	* include/kapi.h (cyg_scheduler_read_lock): New function, to
	return the value of the scheduler lock; this for implementing SPLX
	in the network stack.

	* src/common/kapi.cxx (cyg_scheduler_read_lock): New function.

2000-06-20  Nick Garnett  <nickg@cygnus.co.uk>

	* src/sched/mlqueue.cxx (Cyg_ThreadQueue_Implementation::enqueue):
	Rewrote code to insert threads into priority sorted queue. The
	original code could not cope with a queue all of whose members
	were lower priority than the new thread - it looped for ever. Also
	provided fast paths for common and easily detected cases such as
	adding to a single element queue and adding at the front. By
	taking these cases out early, we can also simplify the code to
	search the queue.

2000-06-16  Gary Thomas  <gthomas@redhat.com>

	* cdl/kernel.cdl: Remove exception tests for CMA230 - not supported
	by hardware.

2000-06-16  Jesper Skov  <jskov@redhat.com>

	* src/intr/intr.cxx (chain_isr): Only call default_isr if no isrs
	in the chain reacted to the interrupt.

2000-06-15  Nick Garnett  <nickg@cygnus.co.uk>

	* include/mutex.hxx (class Cyg_Condition_Variable): Added an
	inline function, get_queue(), to return a pointer to the
	underlying thread queue. To be used mainly for comparing with a
	thread's current queue to decide whether it is waiting for a
	condition variable.

	* include/kapi.h:
	* src/common/kapi.cxx: 
	Changed return type of cyg_semaphore_wait() to match existing
	behaviour of Cyg_Counting_Semaphore::wait().
	Changed return type of cyg_cond_wait() to match new behaviour of
	Cyg_Condition_Variable::wait().

2000-06-09  Nick Garnett  <nickg@cygnus.co.uk>

	* include/mutex.hxx:
	* src/sync/mutex.cxx:
	Modified non-timeout condition variable wait() API to return
	cyg_bool. A true result indicates that the wait() terminated
	normally. A false result indicates that the wait() was terminated
	as a result of a release() or destroy operation. For most uses
	this distinction is irrelevant, but in some situations it is a
	useful bit of information to have.
	Also modified timeout condition variable wait to reacquire the
	mutex under all circumstances. This is the correct and consistent
	thing to do.

2000-06-08  Jesper Skov  <jskov@redhat.com>

	* src/debug/dbg-thread-demux.c: Use generic HAL feature to allow
	ROM/RAM intercalling.

2000-05-30  Gary Thomas  <gthomas@redhat.com>

	* tests/dhrystone.c: Increase number of test loops for faster
	StrongARM platforms.

2000-05-22  Jonathan Larmour  <jlarmour@redhat.co.uk>

	* cdl/scheduler.cdl (CYGIMP_KERNEL_SCHED_SORTED_QUEUES): Disable by
	default

	* src/sched/mlqueue.cxx (enqueue): Add to end of thread queue even
	when not priority ordered

	* include/mqueue.hxx, include/mqueue.inl:
	Add POSIX-style message queue implementation
	
	* cdl/kernel.cdl: Add mqueue1 test
	* cdl/scheduler.cdl: Add new CYGIMP_KERNEL_SCHED_SORTED_QUEUES option

	* include/sema.hxx: Need thread.inl header, not just thread.hxx
	Make Cyg_Counting_Semaphore::peek() const since it is

	* src/sync/cnt_sem.cxx, src/sync/cnt_sem2.cxx, include/sema2.hxx:
	Make Cyg_Counting_Semaphore{2}::peek() const since it is

	* include/thread.hxx: don't want Cyg_Thread_queue::empty() to be marked
	inline in the class def, otherwise we get warnings elsewhere

	* include/mlqueue.hxx (Cyg_ThreadQueue_Implementation):
	Add set_thread_queue private method
	Add derived class Cyg_SchedulerThreadQueue_Implementation, and
	make scheduler implementation use it instead of
	Cyg_ThreadQueue_Implementation
	
	* src/mlqueue.cxx: Fix typo
	Support  CYGIMP_KERNEL_SCHED_SORTED_QUEUES, i.e. allow insertion
	into thread queue in order of thread priority, with oldest at the
	front
	(Cyg_ThreadQueue_Implementation::set_thread_queue): Add
	(Cyg_SchedulerThreadQueue_Implementation::enqueue): Add, like old
	one, except make it FIFO instead of LIFO by inserting at end of queue

2000-05-15  Jonathan Larmour  <jlarmour@redhat.co.uk>

	* cdl/counters.cdl (CYGVAR_KERNEL_COUNTERS_CLOCK_DSR_LATENCY): 
	Default to CYGVAR_KERNEL_COUNTERS_CLOCK_LATENCY

2000-05-04  Jonathan Larmour  <jlarmour@redhat.co.uk>

	* include/instrmnt.h: Remove all CYG_UNUSED_PARAMs as they could
	cause problems when used with volatile arguments
	* src/intr/intr.cxx: Use CYG_UNUSED_PARAM to silence warning that
	appears because of the above change.

2000-05-02  Gary Thomas  <gthomas@redhat.com>

	* tests/kintr0.c:
	* tests/intr0.cxx: Correct test for cases when VSR_MIN or
	ISR_MIN are not zero (bad assumption).

2000-05-02  Jonathan Larmour  <jlarmour@redhat.co.uk>

	* cdl/thread.cdl (CYGNUM_KERNEL_THREADS_DATA_LIBC): Don't need libc
	slot. Replace with CYGNUM_KERNEL_THREADS_DATA_ERRNO slot instead.	

2000-04-28  Nick Garnett  <nickg@cygnus.co.uk>

	* src/sched/sched.cxx (unlock_inner):
	A significant change to the behaviour of this function.  The
	new_lock argument contains the value that the scheduler lock
	should have after this function has completed. If it is zero then
	the lock is being released and some extra work (running ASRs,
	checking for DSRs) is done before returning. If it is non-zero
	then it must equal the current value of the lock, and is used to
	indicate that we want to reacquire the scheduler lock before
	returning. This latter option only makes any sense if the current
	thread is no longer runnable, otherwise this function will do
	nothing.

	The result of this is that where we used to "blip" the scheduler
	lock to force a sleep, we now call reschedule(), which calls
	unlock_inner() with the current sched_lock value. The important
	difference is that there is not now the brief window between the
	calls where the lock is unclaimed. It also prevents ASRs being run
	at inopportune moments. In future this will also allow us to force
	threads to sleep even when they are deeply nested in the scheduler
	lock.

	* include/mutex.hxx:
	Added Cyg_Mutex::get_owner() to return pointer to owning thread.
	
	* include/sched.hxx:
	* include/sched.inl:	
	Added new_lock argument to unlock_inner(), added reschedule().
	Made set_asr_inhibit() and clear_asr_inhibit() available even when
	ASRs are disabled.

	* include/mboxt.inl:
	* src/sync/bin_sem.cxx: 
	* src/sync/cnt_sem.cxx:
	* src/sync/flag.cxx: 
	* src/sync/mutex.cxx: 
	Converted instances of "blipping" the scheduler lock into calls to
	Cyg_Scheduler::reschedule(), which is better behaved. Some calls
	to set_asr_inhibit() and clear_asr_inhibit() also added in various
	places.

2000-04-26  Jesper Skov  <jskov@redhat.com>

	* include/clock.hxx:
	* src/common/clock.cxx:

	Added timeslicing enable support.

	* cdl/thread.cdl:

	Adjust documentation URLs.

2000-03-27  Gary Thomas  <gthomas@redhat.com>

	* tests/except1.cxx: 
	* tests/kexcept1.c: Avoid trying to generate data access errors
	on platforms that don't support them.

	* tests/kcache1.c: Ignore test if no [data] caches defined.

	* tests/stress_threads.c: Infer minimal configuration for platforms
	with small amount of memory (as opposed to platform special cases).

	since it has children now

2000-02-17  Jesper Skov  <jskov@redhat.com>
	CR101202, CR902078

	* src/common/clock.cxx: Rework last change - change types of
	clock_dsr_read and delta to unsigned instead

2000-01-31  Jonathan Larmour  <jlarmour@redhat.co.uk>

	* src/common/clock.cxx (isr): Use HAL_CLOCK_LATENCY, not HAL_CLOCK_READ
	(dsr): Likewise
	
	* cdl/counters.cdl (CYGVAR_KERNEL_COUNTERS_CLOCK_DSR_LATENCY): 
	Copy configury for this option here from include/pkgconf/kernel.h - it
	was left behind by accident

2000-01-31 Simon FitzMaurice  <sdf@cygnus.co.uk>
  * cdl/*.cdl:

  Adjust help URLs in line with new doc layout.
  
2000-01-31  Jesper Skov  <jskov@redhat.com>

	and from this clock resolution and others.

	* include/clock.inl (convert): New Cyg_Clock member.

	factorize a rational (or very near neighbour) to help with clock
	tick conversions for a particular clock.

	* tests/clockcnv.cxx: New file: test the clock converters.

	* tests/PKGconf.mak (TESTS): Add clockcnv to the tests.

	* cdl/kernel.cdl: Add clockcnv to the tests.

2000-01-20  Hugo Tyson  <hmt@cygnus.co.uk>

	* cdl/synch.cdl
	(CYGSEM_KERNEL_SYNCH_MUTEX_PRIORITY_INHERITANCE_SIMPLE_RELAY):
	Change this to an active_if on simple prio-inh.  Was broken.

2000-01-19  Hugo Tyson  <hmt@cygnus.co.uk>

	* cdl/*.cdl: Add descriptions to a number of options &c which were
	lacking same, also tidied up other typos as noticed en passant.
	Also reorganized calculated opts about per-thread-data in
	thread.cdl; these are really for info only.

2000-01-19  Jesper Skov  <jskov@cygnus.co.uk>
	CR 902054
	* tests/stress_threads.c: Don't assert requested priority =
	allocated. Allow some flexibility of handler priorities.

2000-01-13  Hugo Tyson  <hmt@cygnus.co.uk>

	* tests/mutex3.cxx (control_thread): Add a CYG_TEST_INIT();
	Whoops!

2000-01-11  Hugo Tyson  <hmt@cygnus.co.uk>

	* cdl/kernel.cdl: Add new kernel test mutex3, put in to test
	RELAY prio inheritance extension.

	* tests/mutex3.cxx: New test case.  It tests mutex prio
	inheritance - or not - in a multiple thread manner, depending only
	on delays and the clock, so it tests that scheduling does the
	right thing, rather than simply checking reported priorities.

	* tests/PKGconf.mak: Add new kernel test mutex3, put in to test
	RELAY prio inheritance extension.

2000-01-11  Hugo Tyson  <hmt@cygnus.co.uk>

	* cdl/synch.cdl: New config option added,
	(CYGSEM_KERNEL_SYNCH_MUTEX_PRIORITY_INHERITANCE_SIMPLE_RELAY).

	* include/pkgconf/kernel.h: New config option added,
	(CYGSEM_KERNEL_SYNCH_MUTEX_PRIORITY_INHERITANCE_SIMPLE_RELAY).
	It is a child of ..._PRIORITY_INHERITANCE_SIMPLE and is really
	only there to turn off if you really want the old implementation.

	* src/sync/mutex.cxx (unlock): Add call to
	Cyg_SchedThread::relay_priority() when relinquishing the mutex, in
	order to relay any raised priority to the new owner.  Also count
	the mutex we are waiting for as well as those held for correct
	recovery in the case of inheriting priority then being killed, for
	example.

	* include/sched.hxx (class Cyg_SchedThread::relay_priority): New
	member function declared.

	* src/sched/sched.cxx (Cyg_SchedThread::relay_priority): New
	member function to implement pass-it-on or "discovered ceiling"
	priority inheritance extension to the simple algorithm.  Also use
	get_current_priority() in Cyg_SchedThread::inherit_priority() to
	let this work.

2000-01-11  Hugo Tyson  <hmt@cygnus.co.uk>

	* include/clock.hxx (class Cyg_Counter::counter): make the counter
	volatile, otherwise a busy-wait loop for the real time clock to
	change never completes.

1999-12-23  Hugo Tyson  <hmt@cygnus.co.uk>

	* src/sched/sched.cxx (inherit_priority): Fix bug; inheriting a
	2nd time would overwrite the saved initial_priority, so
	disinheriting had no effect.

1999-12-13  Jonathan Larmour  <jlarmour@cygnus.co.uk>

	* tests/tm_basic.cxx (run_alarm_tests): Add new measurement of
	latency between alarm firing and thread resume

1999-12-13  Jonathan Larmour  <jlarmour@cygnus.co.uk>

	* cdl/kernel.cdl: Fix some minor mistakes in the lists of tests to
	build conditionally

1999-12-08  John Dallaway  <jld@cygnus.co.uk>

	* cdl/kernel.cdl:

	Conditionally build the tests 'stress_threads', 'kcache1' and
	'kcache2'.

1999-11-30  Hugo Tyson  <hmt@cygnus.co.uk>

	* src/common/kapi.cxx (cyg_scheduler_lock, cyg_scheduler_unlock):
	assert good range for sched lock, and be defensive anyway.  This
	is in response to a long time taken to track down a "unlocked too
	many times" bug.

1999-11-24  Gary Thomas  <gthomas@cygnus.co.uk>

	* tests/tm_basic.cxx: Size tests based on available resources,
	using MLT files.  Fall back if not available.

1999-11-22  Nick Garnett  <nickg@cygnus.co.uk>

	* src/sched/bitmap.cxx (Cyg_Scheduler_Implementation::add_thread):
	Fixed typo in assertion, and moved it to a more useful place.

1999-11-03  John Dallaway  <jld@cygnus.co.uk>

	* cdl/kernel.cdl: Define all tests.

	clear_timer() is a static which always affects the executing

	"foo->clear_timer()" calls to make this less confusing.
	Ditto set_timer().
	Changed a "clear_timer()" call to "timer.disable()" and added one
	so that they affect _this_ thread, the thread which is being
	kill()ed or reinitialize()d rather than the killer or the
	resuscitator.  Otherwise the alarm list can still get a loop in
	it when a thread's killed when waiting with a timeout and
	restarted soon enough.
	
1998-10-08  Hugo Tyson  <hmt@cygnus.co.uk>

	In general, these changes are to support create/delete of uITRON
	objects; this requires that an object can be destroyed whilst
	there are threads waiting on it, and that they shall be awoken
	with a specific return code.

	* include/thread.hxx:
	Cyg_Thread::DESTRUCT added to wake reasons, to deal with an object
	being destroyed whilst a thread is waiting on it; it's handled in
	a manner very similar to release() and BREAK wake_reason.
	
	* src/common/thread.cxx: 
	thread_entry(): threads now exit() if the entry_point returns.
	Cyg_Thread() constructors now initialize wake_reason to NONE.
	reinitialize() clears any pending timeout before calling
	constructors.
	counted_sleep( [timeout] ) now both deal with the wake reason in
	general, and with DESTRUCT in particular.
	exit() now clears any pending timeout.
	kill() now force_resumes the thread first.
	kill() now does not explicitly remove the thread from any queue
	it's on; wake() does that for you anyway.
	delay() clears the timer just in case and handles DESTRUCT
	properly.
	DESTRUCT added to various switches for completeness.

	The fixes to counted_sleep()[x2] and kill() are a bugfix for
	PR#17688.

	* include/flag.hxx:
	* src/sync/flag.cxx:
	Add an argument, defaulting to 0, to the constructor which sets
	the initial flag value.
	Add handing of DESTRUCT wake reason.
	Add a destructor which wakes all threads with DESTRUCT
	wake_reason.

	* include/mboxt2.inl:
	Add handing of DESTRUCT wake reason.
	Add a destructor which wakes all threads with DESTRUCT

	* src/sync/cnt_sem2.cxx:

	Add a destructor which wakes all threads with DESTRUCT

	* include/thread.inl (init_context):
	Changed CYG_DEBUG to CYGPKG_INFRA_DEBUG.

Tue Sep 15 09:35:14 1998  Jesper Skov  <jskov@cygnus.co.uk>
	PR 17236

	* src/common/clock.cxx (add_alarm): A retriggering alarm called
	with a trigger time in the past or now will be assigned a new
	trigger time. Don't find the counter list until the final trigger
	time is known.
	Also added a few #else error statements to catch a situation where
	no CYGIMP_KERNEL_COUNTERS_x_LIST implementation config is
	selected.
	
	* tests/clock0.cxx: Added extra ASSERT to ensure alarms enabled
	with a trigger time of now or in the past actually fire.
	* tests/kclock0.c: Same.
	
1998-09-15  Bart Veer  <bartv@cygnus.co.uk>

	* include/pkgconf/kernel.h:
	Cleaning up coonfiguration data (mostly improving the
	descriptions). 

Mon Sep 14 11:08:59 1998  Jesper Skov  <jskov@lassi.cygnus.co.uk>
        PR 17230

	* include/pkgconf/kernel.h: CYGIMP_KERNEL_INTERRUPTS_CHAIN
	requires CYGIMP_HAL_COMMON_INTERRUPTS_CHAIN.

1998-09-14  Mark Galassi  <rosalia@cygnus.com>

Fri Sep 11 19:18:28 1998  Hugo Tyson  <hmt@masala.cygnus.co.uk>

	* include/clock.hxx (class Cyg_Alarm): 
	* src/common/clock.cxx (Cyg_Alarm::add_alarm): 
	PR#17182
	Move the code to synchronize a repeating alarm which had been
 	firing in the dim and distant past with times in the future, which
 	had been inline in Cyg_Alarm::enable(), into a function of its
 	own, Cyg_Alarm::synchronize().  Call it from Cyg_Alarm::enable()
	and also from add_alarm() when the immediate time to fire is now
	or in the past; otherwise an initial time of, say, NOW-10 with an
	interval of 5 would just get lost.  Also corrected/commented the
	logic there to allow an alarm's handler to cancel itself.
	
Wed Sep  9 17:43:26 1998  Hugo Tyson  <hmt@cygnus.co.uk>

	* src/common/delete.cxx: 
	Control the provision of empty delete functions rather better, via
	an explicit option from the libc package.  Read the rather lengthy
	comment in delete.cxx for the explanation.
	Also note that the correct place for this functionality is in the
 	infrastructure, and the same should be done for the C++ new
 	functions also.

1998-09-09  Nick Garnett  <nickg@cygnus.co.uk>

	* src/common/thread.cxx:
	combined separate next_unique_id variables in both constructors.
	This would have caused duplicate thread ids to be generated.

	* include/thread.inl:
	Added code to initialize Cyg_HardwareThread::saved_context.

	* src/debug/dbg-thread-demux.c: 
	* src/debug/dbg_gdb.cxx:
	Many changes to get thread API working with Cygmon. Debug code
	currently left in place until complete testing is possible.

Tue Sep  8 17:17:32 1998  Hugo Tyson  <hmt@cygnus.co.uk>

	* include/pkgconf/kernel.h (CYGNUM_KERNEL_COUNTERS_RTC_PERIOD):
	Set up a sensible default RTC for CYG_HAL_MN10300_SIM different
 	from that for the MN103002 or CYG_HAL_MN10300_STDEVAL1, so that
 	sim tests run in less than geological time.  This is the same as
 	the default value of before.

	* src/sched/mlqueue.cxx (timeslice):

	these consumes the whole quantum.

	* include/pkgconf/kernel.h: 
	Moved and renamed CYG_DIAG_USE_DEVICE to infra and to
	CYGDBG_INFRA_DIAG_USE_DEVICE; kernel.h now includes infra.h as
	well as hal.h to ensure all its clients get the info too.
	
	* include/intr.hxx (class Cyg_Interrupt): 
	Add static member interrupts_enabled() to poll the current status;
	just to avoid calling the HAL directly, really.

	* include/diag.h: 
	Now just includes cyg/infra/diag.h, so that kernel-specific
	features can be added later - original diag.h has moved to infra,
	and is that includee.

	* src/PKGconf.mak: 
	Trace folder and its contents elided, now in infra.

	* src/trace/diag.c:
	* src/trace/fancy.cxx:

	Add new get_allocation_size() method to return the size of a
	previously allocated block - trivial for fixed block allocator, and
	requiring a bit of poking around for the variable block allocator.

	This is required for the C library realloc() implementation. Strictly
	this only uses the variable block allocator, but the API can only be
	enhanced by also updating the template. As a result, this also meant
	doing it for the fixed block allocator.

	Change entry points from main() to cyg_start(), and remove return

	no meaning anyway - what could you do with the code?

	* src/test/tsttracc.c, src/test/tsttrace.cxx:
	Also change trace calls (CYG_REPORT_...) to reflect that it is a
	function called cyg_start with no args returning void, rather than
	what it was for main(argc, argv)

Fri Aug 28 09:24:41 1998  Jesper Skov  <jskov@cygnus.co.uk>

	* src/common/kapi.cxx: 
	Change CYG_RELEASE_DEBUG to CYGPKG_INFRA_DEBUG.
	These changes are self-contained, so they can go in right now.
	
Thu Aug 27 15:20:31 1998  Hugo Tyson  <hmt@cygnus.co.uk>

	in coallesce(sic.) code.

1998-08-26  Nick Garnett  <nickg@cygnus.co.uk>

	* include/kapidata.h:

	GDB support in rest of kernel.

1998-08-25  Nick Garnett  <nickg@cygnus.co.uk>

	* include/pkgconf/kernel.h:
	Added CYGIMP_KERNEL_THREAD_GDB_SUPPORT to configure for GDB
	interactions with the kernel.

	* src/debug/dbg-threads-api.h: 
	* src/debug/dbg_gdb.cxx:
	Added these files to repository to support GDB interactions
	with the kernel. Note that dbg-threads-api.h is a copy of a
	file in devo/libstub. Any changes there must be merged in here
	too.

	* src/PKGconf.mak:
	Added debug/dbg_gdb.cxx to COMPILE list.

	* include/thread.inl: 
	* include/thread.hxx:
	Added support for GDB, specifically for thread-aware debugging.

	* include/intr.hxx:
	* src/intr/intr.cxx:
	Added an extra argument to interrupt_end(): a pointer to
	the saved register state. This is optionally used to provide
	a more interesting saved register state for GDB.

Tue Aug 25 02:36:26 1998  Jonathan Larmour  <jlarmour@cygnus.co.uk>

	warnings

Fri Aug 21 18:46:34 1998  Hugo Tyson  <hmt@cygnus.co.uk>

	* src/common/clock.cxx (enable): 
	Make the maths work right if we only just set up the clock
	thingy.  Unsigned has a lot to answer for; when the next scheduled
	tick was all correct, the delta was -1, which correctly rounds to
	zero in the division.  But it isn't -1 it's 18446744073709551615
 	which gave a shift of 15 in the the uITRON test programs.

	make it a bit more efficient and smaller code.
	
Thu Aug 20 17:37:35 BST 1998  Chris Provenzano  <proven@cygnus.com>

	* include/mvarimpl.inl, include/pkgconf/kernel.h:

	* include/thread.hxx:
	Changed argument to cyg_thread_entry() to CYG_ADDRWORD from
	CYG_ADDRESS.

	* include/ktypes.h:
	Moved constructor priority ordering stuff out to infra/cyg_type.h.

	* include/kapi.h: 
	* src/common/kapi.cxx:
	Added name and priority parameters to cyg_thread_create() and
	swapped stack size and base parameters. These changes are
	currently protected by DAY_OF_CHAOS ifdefs and are therefore
	inactive.

1998-08-19  Nick Garnett  <nickg@cygnus.co.uk>

	* include/pkgconf/kernel.h:

	priority configurations.

Tue Aug 18 16:56:38 1998  Jonathan Larmour  <jlarmour@cygnus.co.uk>

	* include/thread.hxx, include/thread.inl: 
	To silence compiler warnings, move register_exception inline definition
	from the .hxx to the .inl. Also move attach_stack to before the
	constructor where it is invoked from.

1998-08-18  Nick Garnett  <nickg@cygnus.co.uk>

Fri Aug 14 18:10:20 1998  Hugo Tyson  <hmt@masala.cygnus.co.uk>

	* src/common/thread.cxx (exit): 
	Set the state explicitly to EXITED rather than or'ing
	it in; should be safe cos it's what kill does in the normal case.
	Needed to avoid suspend sort of states persisting after death.
	One character changes are always aesthetically pleasing.

Fri Aug 14 17:28:01 1998  Hugo Tyson  <hmt@cygnus.co.uk>

	* include/pkgconf/kernel.h: 
	Add config options as below:

	Add asserts of CYGNUM_KERNEL_MAX_COUNTED_WAKE_COUNT_ASSERT
	and CYGNUM_KERNEL_MAX_SUSPEND_COUNT_ASSERT if they are defined.
	Also lazily tidied format of func hdrs as per code review et al.

1998-08-14  Nick Garnett  <nickg@cygnus.co.uk>

	* include/kapidata.h:
	Added support for thread names and thread housekeeping list.

	* include/ktypes.h:
	Remove inlined new and delete as they aren't strictly permitted and
	they prevent a valid new and delete being defined anywhere else!
	
	* src/common/delete.cxx, src/PKGconf.mak: 
	Add delete.cxx to provide default delete operation for when a C

	Added an alternative constructor to Cyg_Thread which takes
	arguments in new order, and includes a scheduling parameters
	argument. Propagated effects of this through Cyg_SchedThread
	and Cyg_SchedThread_Implementation. This mostly takes the form
	of passing the scheduling parameters through to the constructors.

1998-07-27  Nick Garnett  <nickg@cygnus.co.uk>

	NOTE: The timeouts have for now been left as relative delays, they
	should be converted to absolute timeouts.

	* src/common/thread.cxx:
	Modified code in counted_sleep to allow	for a timeout in the past.
	Added handling of EXIT wake_reason in delay().

1998-07-24  Nick Garnett  <nickg@cygnus.co.uk>

	Reordered code in Cyg_Thread::set_timer() to init the timer after
	wake_reason has been assigned.

	* include/clock.inl: 
	Removed Cyg_Alarm::enable().
	
	* src/sync/mutex.cxx (Cyg_Condition_Variable::wait): 
	Modified order of code in timed version of wait to allow for a
	timout in the past.
	
	* src/sync/cnt_sem.cxx (Cyg_Counting_Semaphore::wait):
	Modified order of code in timed version of wait to allow for a
	timout in the past. Also modified timeout to be absolute rather
	than relative.

	* src/common/thread.cxx (Cyg_Thread::wake):
	Added test for whether a thread is actually asleep before waking

	* src/common/clock.cxx:
	Added code to Cyg_Counter::add_alarm() to deal with alarms
	that trigger now or in the past.
