	  sem to grant the new kthread is running before retunring,
	  substitutes the previous polled wait for an RTAI enabled new khread.

	* base/sched/sched.c: added the possibility of testing different ways
	  to set active_mm for kernel threads.

2015-02-06 Paolo Mantegazza <mantegazza@aero.polimi.it>

	  the new calibration way.

2013-09-29 Paolo Mantegazza <mantegazza@aero.polimi.it>

	* base/sched/sched.c: calibrate the hard timers at the scheduler 
	  insmoding, care of avoiding null timer delays programming.
	* base/sched/sys.c: add the support for an easier determination of 
	  the scheduling latencies of RTAI own kernel tasks.
	* base/arch/x86/hal/hal.c: put the determination of the hardtimers 
	  programming delay in the common hal part.
	* base/arch/x86/calibration/calibration_helper.c: simplify the 
	  calibration of user and kernel space scheduling latencies.

2013-09-24 Paolo Mantegazza <mantegazza@aero.polimi.it>

	* base/include/rtai_schedcore.h: use just one wake up srq handler, 
	  keeping a per cpu list of tasks to be woken up.

2013-08-30 Pierangelo Masarati <masarati@aero.polimi.it>
           Paolo Mantegazza <mantegazza@aero.polimi.it>

	* addons/comedi/GNUmakefile.am: no kernel headers in user space
	* addons/comedi/rtai_comedi.h: do not include linux/compiler.h
	  in user space

2013-08-28 Paolo Mantegazza <mantegazza@aero.polimi.it>

	* base/arch/x86/hal/hal_64.c: aligned to work with Linux-3.x,
	  it is much as its hal_32.c counterpart.

2013-08-27 Pierangelo Masarati <masarati@aero.polimi.it>
           Paolo Mantegazza <mantegazza@aero.polimi.it>

	* configure.in, base/arch/x86/Kconfig: enable hard-soft toggling,
	  by automatically installing a SIGUSR1 Linux signal & handler,
	  using standard Linux KILL support

2013-08-26 Ian Abbott <abbotti@mev.co.uk>

	* configure.in: Some AC_CONFIG_LINKS() go wrong when building
	  outside the source tree.

2013-08-25 Paolo Mantegazza <mantegazza@aero.polimi.it>

	* base/arch/x86/hal/hal_32.c: return to requesting the 8254-PIT 
	  interrupt in rt_timer_request, we care of the related issue,
	  alrady solved in the way of the explanation below, by modifying 
	  the patch.
	* base/arch/x86/hal/hal_64.c: same as above, but, once more, since 
	  X86_64 has an APIC always, it is likely non an issue in this case.

2013-08-22 Paolo Mantegazza <mantegazza@aero.polimi.it>

	* base/arch/x86/hal/hal_32.c: do not request the 8254-PIT interrupt 
	  in rt_timer_request, it is done by the patch already; so if the 
	  related timer handler is installed in advance the following 
	  rtai_request_tickdev will get an error and the related 8254 stuff 
	  will not be initialized.
	* base/arch/x86/hal/hal_64.c: same as above, since X86_64 has an APIC
	  always, it is likely non an issue in this case.

2013-08-20 Paolo Mantegazza <mantegazza@aero.polimi.it>

	* base/arch/x86/hal/hal_32.c: use the irq desc eoi in rt_eoi_irq.
	* base/arch/x86/hal/hal_64.c: same as above.

2013-08-19 Paolo Mantegazza <mantegazza@aero.polimi.it>

2013-08-17 Mark Fortescue <mark@mtfhpc.demon.co.uk>

	* base/addons/rtdm/module.c: split the loop initializing the timers
	  into two parts, fixes possible SMP preemption issues.
	* base/addons/rtdm/xn.h: add missing list pointers at timers
	  initialization.
	  (N.B. a forgotten due recovery of a year old, 2012-08-03, fix 
	  existing in VULCANO CVS already.) 

2013-08-07 Paolo Mantegazza <mantegazza@aero.polimi.it>

        * base/include/rtai_lxrt.h: modified the support and declarations for 
 	  externally forcing a task to soft, so to make it possible toggling 
	  hard_soft by enforcing a signal handler for SIGUSR1, at task init, 
	  providing also a support function to get the pid of the RTAI task 
	  to be toggled using Linux kill.
        * base/sched/sys.c: provided the toggling support handler, adding 
	  a function to return the pid of any RTAI task; notice that the new
	  way wholly substitute the old forcing of a task to soft only. Yet 
	  to be made optionally configurable at RTAI making.

2013-08-03 Paolo Mantegazza <mantegazza@aero.polimi.it>

        * base/arch/x86/hal/hal_32.c: check if irq disable-enable are NULL 
	  and divert to mask_unmask if so, add rt_irq_mask.

	  rtai_sched.h.

2013-07-30 Paolo Mantegazza <mantegazza@aero.polimi.it>

        * base/ipc/msg/msg.c: tightened task and message copying pointer
	  checks.

2013-07-29 Paolo Mantegazza <mantegazza@aero.polimi.it>

        * base/ipc/netrpc/netrpc.c added a missing kclose for x86_64.

2013-07-26 Pierangelo Masarati <masarati@aero.polimi.it>

	* change the making of the schedulers, finally we got rid of a useless
	  double creation of the same scheduler; now the only real scheduler
	  is rtai_sched, legacy is saved by linking lxrt, ksched, up, mup and
	  smp to it.

2013-07-26 Paolo Mantegazza <mantegazza@aero.polimi.it>

        * base/arch/x86/hal/hal.c and hal_32.c: fixed TSC sync support, broken

	  using kernel_thread(...) directly.

2013-07-25 Pierangelo Masarati <masarati@aero.polimi.it>

	* change making configuration so to not include Linux headers for user 
	  space code; it made GCC >= 4.7.2 yell for conflicting definitions

        * base/sched/sched.c: make rtai_isr_sched_handle available and
	  exported always.
        * base/arch/x86/hal/hal.c: moved random number generator to 
	  base/include/rtai.h, so to have it available anywhere.

	  have it available anywhere.
        * base/include/rtai_nam2num.h: echo a "|null|" for names that are 
	  either 0 or generated through rt_get_name(NULL).

2013-07-24 Paolo Mantegazza <mantegazza@aero.polimi.it>

        * base/sched/api.c: make getting a unique name from registry safer
	  against duplications.

        * base/sched/sys.c: added test to avoid copying from null user space
	  pointers into the kernel space task specific buffer.

2013-07-20 Paolo Mantegazza <mantegazza@aero.polimi.it>

        * base/ipc/netrpc/netrpc.c: aligned to the latest kthreads Linux 
	  support.
        * base/sched/sched.c: rt_signal_wake_up reverted to wake up on 
	  Linux signals hanyhow.

2013-07-18 Paolo Mantegazza <mantegazza@aero.polimi.it>

        * base/sched/sched.c: rt_signal_wake_up will allow hard real time 
	  tasks to receive signals only if the user has indicated to be 
	  willing to accept them by installing a signal handler for SIGTERM.

2013-07-17 Paolo Mantegazza <mantegazza@aero.polimi.it>

        * base/sched/sched.c and sys.c: use RTAI own task pid for Pierre's 
	  intertask messaging stuff.
        * base/include/rtai_lxrt.h: return pid<->task stuff back here, it is 
	  used also elsewhere than in Pierre's intertask messaging stuff.
        * base/ipc/msg/msg.c: use unified rtai own task pids in Pierre's 
	  intertask messaging stuff.

2013-07-16 Paolo Mantegazza <mantegazza@aero.polimi.it>

        * base/include/rtai_lxrt.h: removed call to rt_kthread_init and moved 
	  pid<->rttask stuff into msg.c

2013-07-15 Paolo Mantegazza <mantegazza@aero.polimi.it>

        * base/sched/sched.c: keep formal kthread_init for compatibility, with 
	  task_init behind it, used by msg.c.
        * base/ipc/msg/msg.c: brounght here pid<->rttask inlines from rtai_lxrt 
	  and reworked proxy support.

2013-07-10 Paolo Mantegazza <mantegazza@aero.polimi.it>

        * base/include/rtai_lxrt.h: rtai_print_to_screen is rt_printk now, 
	  added call rt_kthread_init.

2013-07-03 Paolo Mantegazza <mantegazza@aero.polimi.it>

        * base/sched/liblxrt/init.c: used nomore, just an empty code.
        * base/sched/liblxrt/services.c: include RTAI services to be libbed 
	  from the LXRT user space part of header files directly and not 
	  through the inclusion of rtai_schedcore.h.

2013-07-02 Paolo Mantegazza <mantegazza@aero.polimi.it>

        * base/arch/x86/hal/hal_32.c: use CPU_MASK_ALL to fix a quick and
	  dirty, but very very bad hack, in selecting Linux timers for RTAI.

2013-02-28 John Morris <john@zultron.com>

	* base/sched/sched.c: changed set_cpu_allowed to set_cpu_allowed_ptr 
 	  and to cpumask_of_cpu to cpumask_of, to allow compilation against 
	  kernels that have CONFIG_CPUMASK_OFFSTACK=y

	  completes base RTDM testing, that has been already verified to 
	  work also with RTDM based 16550A.

2005-12-22  Roberto Bucher  <roberto.bucher@supsi.ch>

	  x86 task priority registers: in switching back and forth Linux, 
	  inline and macro for anything a user might want to do on her/his
	  own, utility to initialise high irqs Linux does not know; requires
	  local APIC.
	* base/arch/i386/hal/hal.*: uses taskpri when enabled.

	  not MAX_SLOTS macro, they differ in hashed registry.
	* base/sched/api.c: added a missing loop over registered objects to be
	  released at task existing, export max_slots, clean unused code.

	  account for different versions of Linux 2.6.xx too; rare "device
	  not available" traps updated to use new overhauled macros in 
	  asm-i386/rtai_fpu.h.
	* base/sched/sched.c and base/sched/sys.c: updated to use new
	  overhauled macros in asm-i386/rtai_fpu.h.

2005-06-21  Bernd Suessmilch  <Bernd.Suessmilch@uibk.ac.at>

	* base/sched/sched.c:
	* base/sched/sys.c: improved Linux signal catching and dispatching.
	
2005-06-17  Paolo Mantegazza  <mantegazza@aero.polimi.it>

	* base/include/rtai_schedcore.h: pend trasitions to soft mode
	  directly, they are all atomic protected already.
	* base/sched/sched.c: uses above and simplified the trasition to 
	  soft mode handler.

2005-06-16  Paolo Mantegazza  <mantegazza@aero.polimi.it>

	* base/arch/i386/hal/hal.immed: direct vectoring of irqs to the
	  CPU has its tail as for immediate dispatching, to help Linux in
	  the non preemptible case, i.e. under 2.4.xx. It tend to starve
	  otherwise under very very high soft real time load.

2005-06-14  Roberto Bucher  <roberto.bucher@supsi.ch>

        * rtai-lab/scilab/macros/RTAI/RTAICodeGen_.sci: Corrected problem with
	acivation from continous blocks. Better handling of "ode" functions
        * rtai-lab/scilab/devices/rtai_comedi_dio.c: Corrected problem with
	threshold in output block
	
2005-05-31  Paolo Mantegazza  <mantegazza@aero.polimi.it>

	* base/arch/x86_64/hal/hal.immed:
	  and
	* base/include/asm-x86_64/rtai_hal.immed: all features of the 
	  latest i386 version.

2005-05-30  Paolo Mantegazza  <mantegazza@aero.polimi.it>

	* base/arch/i386/hal/hal.immed: rt_printk uses printk directly, 
	  a sync version added also.
	  
2005-05-30  Daniele Gasperini  <gasperin@elet.polimi.it>

	* first port of what needed to use x*6_64.

2005-05-25  Paolo Mantegazza  <mantegazza@aero.polimi.it>

	* base/arch/i386/hal/hal.immed: trap handler modified to use 
	  unwrapped ADEOS event catching.
	* base/sched/sched.immed: all event handlers modified to use
          unwrapped ADEOS event catching; depends on the definition of the
	  macro "UNWRAPPED_CATCH_EVENT", to be defined in rtai_hal.h.
	* base/include/asm-i386/rtai_hal.immed: enabled macro to use 
	  unwrapped event catching.
	* base/arch/i386/patches: modified handle_event to avoid wrapping
	  event and related data.

2005-05-25  Roberto Bucher  <roberto.bucher@supsi.ch>

        * rtai-lab/scilab/macros/RTAI/RTAICodeGen_.sci: Added checks for the
	dialog box values
        * rtai-lab/scilab/macros/RTAI/SetTarget_.sci: Added checks for the
	dialog box values
	

2005-05-24  Paolo Mantegazza  <mantegazza@aero.polimi.it>

	* base/include/asm/rtai_hal.immed: do not double marking in hard 
	  real time, in cpu_realtime, the depth count is more than enough.
	* base/arch/i386/hal/hal.immed: lock out Linux directly from 
	  interrupt handlers; avoid dispatching irqs completely.
	* base/sched/sched.immed: care of avoiding Linux locking when done
	  in irq handler already, enable immediate sched on ipi without
	  dispatching.

2005-05-23  Roberto Bucher  <roberto.bucher@supsi.ch>

        * rtai-lab/scilab/rtmain.c: Support for continous blocks
        * rtai-lab/scilab/macros/RTAI/*: RTAICodeGen_.sci modified and compatible with 
	  Scilab-3.1 CVS with support for continous blocks
	  Added subdirectory "RT_templates" for tmemplate Makefiles
	  Added New function "SetTarget_.sci" to handle template Makefile and
	  continous code generation.

2005-05-18  Philippe Gerum  <rpm@xenomai.org>

	* configure.in: stop configuring if Linux REGPARMS is set.

2005-05-18  Paolo Mantegazza  <mantegazza@aero.polimi.it>

	* base/include/rtai_malloc.h: practically break any constraint in
	  dynamic memory allocation.

2005-05-13  Paolo Mantegazza  <mantegazza@aero.polimi.it>

        * base/sched/sched.immed: 
	  - changed coding of circular pending lists,
	  - pending wake up macro transferred to rtai_schedcore.h,
	  - parametrised give_back_to_linux to distinguish between raw
	    use and internal hard/soft transitions following Linux use,
	  - use ADEOS virq directly for waking up Linux tasks from RTAI.
        * base/sched/api.c: sleeping tasks wake up substituted with the more
	  general rt_task_masked_unblock, so that it becomes just a #define 
	  subcase of it.
        * base/sched/sys.c: cares of the paremetrised give_back_to_linux.
        * base/arch/i386/hal.immed: 
	  - cleaned unused/useless stuff,
	  - layout restyling,
	  - old cpu affinity state is saved no more, as it could wrongly 
	    restate an unintended mask in case of repeated calls, user must
	    care of it; to such an aim the set affinity function return the
	    previous state,
	  - optional stalling of the RTAI domain in hard mode, under control
	    of the STALL_RTAI_DOMAIN macro,
        * base/include/asm-i386/rtai_hal.immed: changes to support consistency 
	  when STALL_RTAI_DOMAIN is used.
        * base/include/rtai_schedcore.h: defines pending wake up macros for
	  any need. 
        * testsuite/kern/latency/, testsuite/user/latency/: output conforming
	  to 3.2, i.e with overall count of periodic reschedules displayed
	  also.

2005-05-03  Roberto Bucher  <roberto.bucher@supsi.ch>

        * rtai-lab/scilab/macros/RTAI/*: Added new blocks

2005-04-27  Panagiotis Issaris <panagiotis.issaris@mech.kuleuven.ac.be>
	* testsuite/{user,kernel}/{latency,preempt}/display.c: output is now 
	in tabular format and output uses the same units for each test.
	* testsuite/user/latency/display.c: show overall maximum latency.

2005-04-20  Roberto Bucher  <roberto.bucher@supsi.ch>

        * rtai-lab/scilab/macros/RTAI/*: Scicos ports are now set automatically
	* rtai-lab/scilab/devices/*: library files modified for port set automatically
	* rtai-lab/scilab/example/tes.cos: Modifies with the new scicos blocks

2005-04-13  Paolo Mantegazza  <mantegazza@aero.polimi.it>

        * begin new development cycle, aligning to stable vulcano, i.e. 3.2.
