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
(2014-8-12)
7.5 2014-xx-xx Gregory Nutt <gnutt@nuttx.org>
* clock/clock_systimespec.c and sched/clock/clock_gettime.c: When
reading the system timer, don't read a struct timespec, convert it
to a fake tick count, then back to a timespec (2014-8-15).
* sched/clock/Make.defs, clock_gettime.c, clock_settime.c, include/time.h,
nuttx/clock.h, configs/vsn/src/sif.c: Remove CLOCK_ACTIVETIME. It is non-
standard, unused, and gets in the way of maintaining clocks (2014-8-15).
* libc/time/lib_localtime.c: Modified to that the coding style is much
closer to NuttX coding style. The local header files private.h and
tzfile.h were removed and incorporated into lib_localtime.c. All
conditional compilation within lib_localtime.c that unconditionally
evaluated to FALSE was removed (2014-8-15).
* drivers/net/Kconfig and include/nuttx/arch.h: Standardize a PHY
interrupt attachment interface (2014-8-16).
* configs/Kconfig, sama5d3-xplained, sama5d3x-ek, and sama5d4-ek:
Convert existing board specific PHY interrupt interfaces to use newly
defined standard interface (2014-8-16).
* include/net/slip.h: Move SLIP prototypes from net.h to slip.h
(2014-8-16).
* include/net/net.h and net/: Fix some missing function headers
(2014-8-16).
* drivers/net/phy_notify.c, include/nuttxarch.h, net/phy.h, and
ioctl.h: Add support for an ioctl that can be used to notify an
application when there is a change in the network status signalled
by a PHY interrupt (2014-8-16).
* drivers/net/phy_notify.c, include/net/if.h, ioctl.h, netdev.h, phy.h,
and net/netdev/netdev_ioctl.c: Finishes the ioctl definition to
subscribe to PHY events. Revamp network ioctl signature to support
arguments other than struct mii_ioctl_data (2014-8-16).
* arch/arm/src/stm32/stm32_eth.c: Modified to support the change to the
network ioctl signature changes. Also add support for new ioctl to
setup PHY event notifications (2014-8-16).
* arch/arm/src/sama5/sam_emaca.c, sam_emacb.c, and sam_gmac.c: Implement
all network ioctls, including the new ioctl to setup PHY event
notifications (2014-8-16).
* include/net/if.h: Add some helper macros to make the code that uses
the ioctls a little more compact (2014-8-17).
* libc/stdio/lib_sscanf.c: NuttX libc tried to guess how many characters
to parse, extracted them into a buffer, then ran strtol() on that
buffer. That guess is often wrong. A better approach would be to
call strtol() directly on the input data, using the endptr return
value to determine how many characters to skip after parsing. From
Kosma Moczek (2014-8-18).
* net/arp/arp_dump.c: Add missing configuration option to select
dumping of ARP packet headers. Move ARP dumping logic from
arp_inout.c to its own file (2014-8-18).
* net/arp/arp_out.c: Move arp_out() from arp_inout.c to its own file
(2014-8-18).
* net/arp/arp_arpin.c: Move arp_arpin() from arp_inout.c to its own file
(2014-8-18).
* net/arp/arp_ipin.c: Rename arp_inout.c to arpipin.c because that is
all that is left in the file (2014-8-18).
* net/arp/arp_format.c: Move the logic that formats an ARP packet into a
separate file where it can be re-used. (2014-8-18).
* net/arp/arp_out.c and net/pkt/pkt_send.c: Change how the IFF_NOARP
flag is handled. This should be set only when data is moved into the
buffer and cleared after tested by the ARP logic. Setting it globally
can cause packets to be sent with no valid MAC addresses (2014-8-18).
* net/arp/arp_send.c: Partial implementation of logic to send ARP
requests to assure that an IP address mapping is present in the ARP
table (2014-8-18).
* net/arp/arp_poll.c: Finished the implementation of logic to send ARP
requests. Complete, fully hooked into the networking logic, and ready
for test (but still untested) (2014-8-18).
* net/icmp/icmp_ping.c, net/socket/net_sendfile.c, sendto.c,
net/tcp/tcp_send_buffered.c, and tcp_send_unbuffered.c: If
CONFIG_NET_ARP_SEND is enabled, then all ICMP, TCP, and UDP send
operations will call arp_send() before attempting the real send
operation. arp_send() will check if the the IP address mapping is in
the ARP table and, if not send ARP requests periodically until it is.
This eliminates losing the first outgoing message because there is not
mapping in the ARP table (2014-8-18).
* net/arp/arp_notify.c, arp_send.c, arp_arpin.c, and arp.h: Add
signalling logic so that we do not have to wait so long with the
network responses to ARP requests quickly (2014-8-19).
* include/nuttx/lcd/ili9341.h: \Add a register definition header file
for the ILI9341 LCD (2014-8-19).
* net/arp/Kconfig: ARP request logic is no longer EXPERIMENTAL
(2014-8-20).
* net/arp/arp_send.c: ARP request logic needs to do the right thing if
(1) the address is a broadcast or multicast address, and (2) if the
IP address lies outside of the network. Problem noted by Manuel Stuehn
(2014-8-20).
* configs/sam4e-ek/src/Kconfig and src/sam_ili9341.c: Add ILI9341-based
* configs/sam4e-ek/nxwm: Add an NxWM configuration for the SAM4E-EK
(2014-8-21).
* configs/viewtool-stm32f107: Refresh some configurations (2014-8-20).
* nuttx/sched/wdog: If we run out of pre-allocated watchdog times, the
logic will allocate additional timers from the heap. A reserve of
pre-allocated watchdog timers is maintained so that there will always
be timers available for interrupt handlers (2014-8-21).
* include/nuttx/wdog.h (and many affected files): wdog.h does not
contain any application interface, only internal OS interface.
Further, it is non-standard. Move wdog.h from include/ to
include/nuttx (2014-8-21).
* Documentation/NuttxPortingGuide.h: For the same reason as above, move
the description of the watchdog timer interfaces from the Users Guide
to the Porting Guide (2014-8-21).
* arch/arm/src/stm32/stm32_uart.h: STM32 F401: Correct support for
USART6 on this chip. From Freddie Chopin (2014-8-22).
* nuttx/sched/wdog and include/nuttx/wdog.h: Add support for statically
allocated watchdog timer (also eliminate some unconvential typing)
(2014-8-22).
* configs/p112/ostest and tools/mkdeps.c: Changes to try to get P112 to
compile with laster SDCC (it still does not) (2014-8-22).
* sched/group/group_leave.c: Need to release the address environment when
the task group is released (2014-8-22).
* mm/mm_granreserve.c and and mm_granmark.c: gran_reserve(): Add a
new function to reserve unallocatable regions in the granule heap
(2014-8-23).
* include/nuttx/pgalloc.h and mm/mm_pgalloc.c: Add a simple page
allocator based on the existing NuttX granule allocator. I am not
certain if the granule allocator is sufficiently deterministic for
long range use, but it gets get a page allocator in place for testing
very quickly (2014-8-23).
* ARMv7-A: Add skeleton implementation and build support for process
address environments (2014-8-23).
* Many files: Change CONFIG_ADDRENV to CONFIG_ARCH_ADDRENV; change how
it is selected -- the architecture must first declare support
(2014-8-24).
