safe since the new features are only enabled by this option (Safer
but not 100% safe since it does not protect from typos and other
dumb errors) (2014-8-6).
* arch/sim/src/Makefile, up_idle.c, up_internal.h, and up_tickless.c:
Add support for a simulated interval timer support verification of
the tickless OS (2014-8-6).
* include/nuttx/arch.h: Added another tickless OS interface to get
the timer remaining on the interval timer (2014-8-6).
* include/nuttx/clock.h, sched/clock_initialize.c and clock_internal.h:
If CONFIG_SCHED_TICKLESS is defined, then the global variable
g_system_timer does not exist (2014-8-6).
* sched/Makefile: Don't build in sched_processtimer.c if
CONFIG_SCHED_TICKLESS is selected (2014-8-6).
* sched/clock_gettime.c and clock_settime.c: Use the clock_systimer()
macro, do access the g_system_timer() global directly (2014-8-6).
* sched/clock_systimer.c: Uses interval timer interfaces to get the
time if CONFIG_SCHED_TICKLESS is selected (2014-8-6).
* sched/sched_timerexpiration.c, Makefile, os_internal.h,
sched_addreadytorun.c, sched_processtimer.c, sched_unlock.c,
wd_cancel.c, wd_internal.h, and wd_start.c: Implements the
tickless OS (2014-8-7).
* Many files: Remove CONFIG_DISABLE_CLOCK. Why? This option is not
really very useful and was only selected in a few unusable, mostly
unusable configurations anyway (m9s12/ostest, kl25z/minnsh,
z180/ostest, 8051, sh1, z80, and z8). The only real loss is probably
to the kl25z/minsh configuration . And with the addition of the
tickless OS, I just wanted to make the pain go away (2014-8-7).
* Many files: Change CONFIG_MSEC_PER_TICK to CONFIG_USEC_PER_TICK.
This gives more options for system timers in general, but more
importantly, let's us realize higher resolution for the case of
CONFIG_SCHED_TICKLESS=y -- of course, at the risk of some new
integer overflow problems 2014-8-7).
* Many files: Change all time conversions. Yech. New timer units
in microseconds breaks all existing logic that used milliseconds
in the conversions. Something likely got broken doing this,
probably because I confused a MSEC2TICK conversion with a TICK2MSEC
conversion (2014-8-7).
* arch/sim/src/up_tickless.c and sched/sched_timerexpiration.c: The
tickless OS now appears fully functional and passes the OS test
on the simulator with no errors (2014-8-7).
* sched/mqueue: Move POSIX message queue files from sched/ to
sched/mqueue (2014-8-8).
* sched/signal: Move signal-related files from sched/ to sched/signal
(2014-8-8).
* sched/pthread: Move all pthread files from sched/ to sched/pthread
(2014-8-8).
* sched/semaphore: Move POSIX counting semaphore files from sched/ to
sched/semaphore (2014-8-8).
* sched/environ: Move environment files from sched/ to sched/environ
(2014-8-8).
* sched/group: Move group logic from sched/ to sched/group (2014-8-8).
* sched/wdog: Move watchdog functions from sched/ to sched/wdog
(2014-8-8).
* sched/irq: Move interrupt dispatch logic from sched/ to sched/irq
(2014-8-8).
* sched/clock: Move clock functions from sched/ to sched/clock
(2014-8-8).
* sched/timer: Move POSIX timer files from sched/ to sched/timer
(2014-8-8).
* sched/paging: Move page fill sources from sched/ to sched/paging
(2014-8-8).
* sched/init: Move initialization functions from sched/ to sched/init
(2014-8-8).
* sched/errno: Move errno related files from sched/ to sched/errno
(2014-8-8).
* sched/task: Move task control files from sched/ to sched/task
(2014-8-8).
* sched/: Move a few files in sched/ that did not seem to have a home to
sched/signal and sched/task (2014-8-8).
* sched/sched: Move scheduler files from sched/ to sched/sched
(2014-8-8).
* (Many files): Replace os_internal.h with sched/sched.h in files that
actually reference something in sched.h (2014-8-8).
* sched/task/exit.c: Move sched/exit.c to sched/task/exit.c (2014-8-8).
* (Many files): Remove os_internal.h it has been replace by several new
header files under sched/. There have been some sneak inclusion paths
via os_internal.h, so expect a few compilation errors for some
architectures (2014-8-8).
* Documentation/NuttxPortingGuide.html, arch/sim/src/up_tickless.c, and
include/nuttx/arch.h: Fix errors in documentation and comments related
to the Tickless OS. From Vijay Kumar (2014-9-9).
* arch/arm/src/sama5/sam_tc.c and .h: Can now handle non-constant
BOARD_MCK_FREQUENCY. Also now supports methods to attach user
interrupt handlers (2014-8-9).
* drivers/audio/audio_null.c: Fix an error in a variable name
(2014-8-9).
* arch/arm/src/sama5/sam_oneshot.c, .h, Kconfig, Make.defs, sam_tc.c,
.h, and sam_adc.c: Add support for a one-shot timer wrapper around
the low-level timer/counter logic. This also involved several changes
that rippled into the ADC driver (untested) (2014-8-9).
* arch/arm/src/sama5/sam_freerun.c, .h, Kconfig, and Make.defs: Add
support for a free-running timer wrapper around the low-level
timer/counter logic (2014-8-9).
* arch/arm/Kconfig, src/sama5/sam_tickless.c, Kconfig, Make.defs: Use
the one-shot and free-running timers to implement tickless OS support
for SAMA5 (2014-8-9).
* arch/arm/src/sama5/sam_oneshot.c and sam_tc.c: Fix several bugs in
timer/counter interrupt logic and one-shot timer logic. Comments and
debug output updated in additional files (2014-8-10).
* sched/wdog/wd_start.c: Correct a bug in Tickless OS support: logic to
detect changes in head of timer list was wrong (2014-5-10).
* sched/sched/sched_timerexperation.c, sched.h, and wdog/wd_start.c: In
tickless mode, need to stop the interval timer before inserted a new
delay into the timer list. Otherwise, the time is incorrect on the
first entry of the list (2014-8-11).
* arch/arm/src/sama5/sam_freerun.c and sam_oneshot.c: Correct bad time
conversion, 1000000 not 1000 to convert seconds to microseconds
(2014-8-11).
* sched/sched/sched_timerexpiration.c: Fix inaccurate time conversion.
Remove MSEC_PER_TICK from calculation and convert uint32_t to uin64_t
(2014-8-11).
* libc/time/lib_localtime.c, private.h, tzfile.h and several header and
make-related files: Adds support for localtime. From Max Neklyudov
