82debdc213 Make task_init() and task_activate() internal OS functions.
-Move task_init() and task_activate() prototypes from include/sched.h to include/nuttx/sched.h.  These are internal OS functions and should not be exposed to the user.
-Remove references to task_init() and task_activate() from the User Manual.
-Rename task_init() to nxtask_init() since since it is an OS internal function
-Rename task_activate() to nxtask_activate since it is an OS internal function

3dca5eba15 Completes the Implementation of the TLS-based errno
- Remove per-thread errno from the TCB structure (pterrno)
- Remove get_errno() and set_errno() as functions.  The macros are still available as stubs and will be needed in the future if we need to access the errno from a different address environment (KERNEL mode).
- Add errno value to the tls_info_s structure definitions
- Move sched/errno to libs/libc/errno.  Replace old TCB access to the errno with TLS access to the errno.

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.

b290160b3b Rename sched_process_timer to nxsched_process_timer. That is the appropriate name for an internal sched/ function (still many named incorrectly). 2019-03-20 19:27:40 -06:00

dc8c814ca3 Squashed commit of the following:
Fixed coding standard error in several files.  Use of while( is incorrect; a space is required between while and (.  Also ran tools/nxstyle and fix thoses complaints as well in most files.

    Changes to comply with coding standard.  Mostly focused on files with missing space after keyword in if(, switch(, and for(.  Offending files also got changes to comply with tools nxstyle.  If there were logs of nxstyle complaints, the file also got a taste of tools/indent.sh.  Still need to fix occurrences of while( with missing space.  There are a lot of them.

a64869aa67 CONFIG_NFILE_DESCRIPTORS=0 can no longer be used to disable the file system. NuttX with no file system does not make sense.
Squashed commit of the following:

    configs/:  The few configurations that formerly set CONFIG_NFILE_DESCRIPTORS=0 should not default, rather they should set the number of descriptors to 3.
    fs/:  Remove all conditional logic based on CONFIG_NFILE_DESCRIPTORS == 0
    tools/:  Tools updates for changes to usage of CONFIG_NFILE_DESCRIPTORS.
    syscall/:  Remove all conditional logic based on CONFIG_NFILE_DESCRIPTORS == 0
    libs/:  Remove all conditional logic based on CONFIG_NFILE_DESCRIPTORS == 0
    include/:  Remove all conditional logic based on CONFIG_NFILE_DESCRIPTORS == 0
    drivers/:  Remove all conditional logic based on CONFIG_NFILE_DESCRIPTORS == 0
    Documentation/:  Remove all references to CONFIG_NFILE_DESCRIPTORS == 0
    binfmt/:  Remove all conditional logic based on CONFIG_NFILE_DESCRIPTORS == 0
    arch/:  Remove all conditional logic based on CONFIG_NFILE_DESCRIPTORS == 0
    net/:  Remove all conditional logic based on CONFIG_NFILE_DESCRIPTORS == 0
    sched/:  Remove all conditional logic based on CONFIG_NFILE_DESCRIPTORS == 0
    sched/Kconfig:  CONFIG_NFILE_DESCRIPTORS may no longer to set to a value less than 3
    configs/:  Remove all settings for CONFIG_NFILE_DESCRIPTORS < 3

bb623d1e04 This commit renames all internal OS functions defined under sched/task so that they begin with the prefix. For example, nxtask_exit() vs. task_exit().
Squashed commit of the following:

    Trivial, cosmetic
    sched/, arch/, and include:  Rename task_vforkstart() as nxtask_vforkstart()
    sched/, arch/, and include:  Rename task_vforkabort() as nxtask_vforkabort()
    sched/, arch/, and include:  Rename task_vforksetup() as nxtask_vfork_setup()
    sched/:  Rename notify_cancellation() as nxnotify_cancellation()
    sched/:  Rename task_recover() to nxtask_recover()
    sched/task, sched/pthread/, Documentation/:  Rename task_argsetup() and task_terminate() to nxtask_argsetup() and nxtask_terminate(), respectively.
    sched/task:  Rename task_schedsetup() to nxtask_schedsetup()
    sched/ (plus some binfmt/, include/, and arch/):  Rename task_start() and task_starthook() to nxtask_start() and nxtask_starthook().
    arch/ and sched/:  Rename task_exit() and task_exithook() to nxtask_exit() and nxtask_exithook(), respectively.
    sched/task:  Rename all internal, static, functions to begin with the nx prefix.

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. This flag assures that there is only one signal handled at a time. 2019-02-03 15:29:47 -06:00

db24306435 arch/assertion logic: Fix additional places where the test for an IDLE task is incorrect. It is not invalid in all configurations to check for PID==0. However, the logic fixed in these places lackes sufficient intelligence to find the right stack for the CPU IDLE thread and could still show the wrong stack. 2018-12-18 17:45:46 -06:00

ec9265aa95 arch assertions: Correct duplicated logic from commit dbf01d12b7. Checking for PID == zero is not a valid way to test for the IDLE task in all configurations! This is only true in the single CPU configuration. In multiple CPU configurations, there will be a separate IDLE task for each CPU with a different PID. 2018-12-18 17:35:42 -06:00

0af39e1493 arch/: Update all _exit() implementations for all architectures so that they correctly called the scheduler instumentation layer for the new task that runs when the old one exits. This missing instrumentation was confusing the Critical Section Monitor logic with uses this instrumentation to track the state of critical sections. 2018-11-24 18:20:57 -06:00

dbf01d12b7 Assertions: Identify the running task correctly when dumping task state information. It takes time to switch to the target task after g_readytorun has been modified. If panic/assert happen during this period, the dump will contain the incorrect and confusing information due to the difference between the real running task and the return value of this_task(). This change resolve this problem by adding g_running_task to track the real running task through the context switch. 2018-11-15 07:11:51 -06:00
