7774cdd7aa Appease many of nxstyle errors for esp32 related files
I skipped the following files because they were not simple.
I'll create separate PRs.

    arch/xtensa/src/esp32/esp32_cpustart.c
    arch/xtensa/src/common/xtensa_abi.h
    boards/xtensa/esp32/esp32-core/include/board.h

Also, I skipped the following files and directories because
they looked too huge and/or foreign.

    arch/xtensa/include/esp32/tie.h
    arch/xtensa/include/xtensa/xtensa_corebits.h
    arch/xtensa/src/esp32/hardware/
    arch/xtensa/include/esp32/tie-asm.h
    arch/xtensa/include/esp32/core-isa.h
    arch/xtensa/include/xtensa/core.h

I also fixed a few "is is" style typos when unwrapping long lines.

To ensure size_t same as toolchain definition in the first place and rename CXX_NEWLONG to ARCH_SIZET_LONG.  The change also check whether __SIZE_TYPE__ exist before CONFIG_ARCH_SIZET_LONG so our definition can align with toolchain(gcc/clang) definition automatically.

6d69439f58 Call xxx_timer_initialize from clock subsystem
Call xxx_timer_initialize from clock subsystem to make timer ready for use as soon as possiblei and revert the workaround:

commit 0863e771a9
Author: Gregory Nutt <gnutt@nuttx.org>
Date:   Fri Apr 26 07:24:57 2019 -0600

    Revert "sched/clock/clock_initialize.c:  clock_inittime() needs to be done with CONFIG_SCHED_TICKLESS and clock_initialize should skip clock_inittime() for external RTC case since the RTC isn't ready yet."

    This reverts commit 2bc709d4b9.

    Commit 2bc709d4b9 was intended to handle the case where up_timer_gettime may not start from zero case.  However, this change has the side-effect of breaking every implementation of tickless mode:  After this change the tickless timer structures are used before they are initialized in clock_inittime().  Initialization happens later when up_initialize is called() when arm_timer_initialize().

    Since the tickless mode timer is very special, one solution might be to

    1. Rename xxx_timer_initialize to up_timer_initialize
    2  Move up_timer_initialize to include/nuttx/arch.h
    3.  Call it from clock subsystem instead up_initialize

    Basically, this change make timer initialization almost same as rtc initialization(up_rtc_initialize).

    For now, however, we just need to revert the change.

Gregory Nutt
641a98a434 arch/: The saved return register state is available on the user stack. Thic commit reorders some logic so that certain, critical registers are preserved in the TCB. This does not make the logic 100% secure, but does prevent some obvious things. sched/signal/sig_delivery: Add a flag to the TCB to indicate that we are in a signal handler. Use this flag to assure that a there a never attempts to nest signal handling operations on a thread. This was guaranteed before but when locking of pre-emption during signal delivering was eliminated in a previous commit, there was a remote possibility of an attempt to do nested signal handling.

a581d7c2e3 arch/: Relasted to last big change to force interrupts to be disabled. In the SMP case, we still must call leave_critical_section() at least once in order to compensate for the fact that the irqcount was incremented in up_schedsigaction(). 2018-06-06 17:04:12 -06:00
Gregory Nutt
977d41d519 Based on a change recommended by Mark Shulte:
Signal handlers maybe run with interrupts enabled or disabled, depending on how the task the received the signal was blocked. (i.e.: If sem_wait() is called, then we disable interrupts, then block the currently running task). This could be dangerous, because user code would be running with interrupts disabled.

This change forces interrupts to be enabled in up_sigdeliver() before executing the signal handler calling up_irq_enable() explicitly.  This is safe because, when we return to normal execution, interrupts will be restored to their previous state when the signal handler returns.

dd5e47a418 ESP32 core v2: Two changes (1) flushes the UART TX buffer in the esp32 serial shutdown routine. The ROM bootloader does not flush the FIFO before handing over to user code, so some of this output is not currently seen when the UART is reconfigured in early stages of startup. And changes the openocd config file's default flash voltage from 1.8V to 3.3V. This is not necessary right now, but may save some hard-to-debug moments down the track (3.3V-only flash running at 1.8V often half-works and does weird things...) 2016-12-14 08:15:03 -06:00
