Summary:
- Adjust CONFIG_BOARD_LOOPSPERMSEC in all defconfigs
- Add CONFIG_TESTING_GETPRIM to nsh and nshsram
- Add CONFIG_SYSTEM_TASKSET to smp
- NOTE: CONFIG_SCHED_WAITPID is removed because it is selected
Impact:
- The smp app will take longer than before but it's a correct behavior
Testing:
- Tested with getprime, ostest, smp
I2C3 not worked due to it's GPIO pin definition has been missing on board.h.
Fix it through include two pin macros on stm32l4x3xx_pinmap.h to board.h.
GPIO_I2C3_SCL and GPIO_I2C3_SDA is pointing A7 and B4 respectively.
Summary:
- This commit changes spinlock APIs (spin_lock_irqsave/spin_unlock_irqrestore)
- In the previous implementation, the global spinlock (i.e. g_irq_spin) was used.
- This commit allows to use caller specific spinlock but also supports to use
g_irq_spin for backword compatibility (In this case, NULL must be specified)
Impact:
- None
Testing:
- Tested with the following configurations
- spresnse:wifi, spresense:wifi_smp
- esp32-devkitc:smp (QEMU), sabre6-quad:smp (QEMU)
- maxi-bit:smp (QEMU), sim:smp
- stm32f4discovery:wifi

The BaseBoard carries Teensy 4.1 SBC. The complete design
of the baseboard (teensy_bb-1.tdb) is available at
https://gitlab.com/pikron/projects/imxrt-devel/-/tree/master/hw
Attempt is to provide configuration which enables most
of interfaces of the BaseBoard and allows runtime applications

The ARMv7 specifies minimal alignment to be 8 for EABI. Ensure
that sections are placed with even greater minimal alignment.
Sections final alignment should be adjusted according
to alignment of their inputs, but for some reasons some
combinations lead to .ARM.exidx overlap with .data.
When alignment is increased then the direct fetch of the
fill location
_eronly = ABSOLUTE(.);
does not match with final LMA placement of the .data section.
Use constructs which should result in matching .data LMA
address for all cases
_eronly = ABSOLUTE(.);

The BSP MAke.defs line
LDFLAGS += -Map=$(TOPDIR)/nuttx.map
results in absolute path in nuttx-export/scripts/Make.defs
which would mean that each application rebuild would attempt
to modify file inside original build of NuttX system.
Even worse, it prevents linking by GCC, because -Map=xxx/nuttx.map
works directly in LD, it would require -Wl,-Map= for GCC.
Fixed name of map file prevents to define map file by build
system using exported NuttX libraries and link kit.
Change is done to allow OMK template based applications
development for another NuttX BSP

This change improves upon current support for pin interrupts. Before,
a pin interrupt was handled (with nrf52_gpiote_setevent) using one
of the eight available GPIOTE channels. Moreover, it didn't event let
the user specify which channel to use (simply tried to get a free one).
Also, it was buggy since it did not consider unsetting the callback.
Besides GPIOTE channels, there is another way to deal with pin interrupts.
The GPIO peripheral is capable of generating a PORT event
(for the whole GPIO port) depending on the pin SENSE configuration
(HIGH or LOW, or NONE) and GPIO DETECTMODE register
(latching or non-latching).
This change then renames nrf52_gpiote_setevent into nrf52_gpiote_set_ch_event,
maintaining functionality of original function, but now allows specifying
channel (and correctly handles unsetting the callback). Then, a
new nrf52_gpiote_set_pin_event is added, which allows to set a callback
for a given pin. During initialization, interrupt for the PORT event is
enabled and handled in such way that for each pin whose corresponding
bit in LATCH register (indicates the result of pin SENSEing) the
callback for this pin will be invoked. This mechanism means that
every pin can get an ISR. It also avoids using GPIOTE channels for this
purpose which carry higher current consumption.
This new per-pin callback mechanism has some added memory requirement
so it can be disabled and its default is dependant on DEFAULT_SMALL.
When disabled, a callback for the PORT event can be set directly
with nrf52_gpiote_set_port_event
There was only one use of nrf52_gpio_setevent() which was migrated
into nrf52_gpio_set_ch_event() passing channel zero.
In the current compilation environment, the recursive assignment(=) for compile
flags will be delayed until every file is actually need to be compile.
For example:
--------------------------------------------------------------------------------
arch/arm/src/Makefile:
INCLUDES += ${shell $(INCDIR) "$(CC)" $(ARCH_SRCDIR)$(DELIM)chip}
INCLUDES += ${shell $(INCDIR) "$(CC)" $(ARCH_SRCDIR)$(DELIM)common}
INCLUDES += ${shell $(INCDIR) "$(CC)" $(ARCH_SRCDIR)$(DELIM)$(ARCH_SUBDIR)}
INCLUDES += ${shell $(INCDIR) "$(CC)" $(TOPDIR)$(DELIM)sched}
CPPFLAGS += $(INCLUDES) $(EXTRAFLAGS)
CFLAGS += $(INCLUDES) $(EXTRAFLAGS)
CXXFLAGS += $(INCLUDES) $(EXTRAFLAGS)
AFLAGS += $(INCLUDES) $(EXTRAFLAGS)
--------------------------------------------------------------------------------
All compilation options will be included recursively,
which will be delayed until the compilation options are actually used:
tools/Config.mk:
--------------------------------------------------------------------------------
define COMPILE
@echo "CC: $1"
$(Q) $(CC) -c $(CFLAGS) $($(strip $1)_CFLAGS) $1 -o $2
endef
--------------------------------------------------------------------------------
All compile flags to be reexecuted $(INCDIR) as long as one file needs to be compiled,
but in fact, the compilation options have not changed in the current directory.
So the we recommand to change the syntax of assignment
From
Recursive (=)
To
Simple (:=)
In this way, we can ensure that all compilation options are expanded only once and reducing repeated works.

This separation allows to interact with the watchdog from OS code,
for example initiating the watchdog very early on boot. Moreover,
these changes make the lower-half driver support an already running
watchdog, which may happen if there's a bootloader which already

There is a good case on sim platform:
When we input some cmd and click enter key to start application in terminal,
this context will change to application from IDLE loop. Althrough entey key '\r'
has been received to recv buffer and complete post semaphore of reader, but
pollnotify may not be called because context change. So when application run
poll function, because no events happend and poll enter wait, context will
again change to IDLE loop, this pollnotify of IDLE loop will run to send poll
events, poll function of applicaton will wake up. It's wrong!
