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.

621151a523 Fix some macOS sim warnings.
These warnings fix a class of warnings that I saw during CI checks for macOS sim builds.  For example:

    devif/devif_callback.c:111:49: warning: for loop has empty body [-Wempty-body]
                   prev = curr, curr = curr->nxtdev);
                                                    ^
    devif/devif_callback.c:111:49: note: put the semicolon on a separate line to silence this warning

I did not put the semi-colon on a separate line, but used braces.

fc127fd297 sched/signal: Add a generic signal notification facility. Modify the custom IOB available notifier so that it is now just a wrapper around this generic signal notification. This generic signal notification faility will, eventually, be used to support network polling.
Squashed commit of the following:

    mm/iob:  The IOB available notifier is now just a wrapper around the common signal notifier.

    sched/signal:  Add a generic signal notification facility.

    sched/signal/sig_evthread.c:  More trivial naming changes.

    sched/signal:  Rename nxsig_notification() to nxsig_evthread() to make forthcoming naming additions more consistent.

fca07be1df Squashed commit of the following:
Change all calls to mq_send() and mq_timedsend() in the OS to calls to nxmq_send() and nxmq_timedsend(), making appropriate changes for differences in return values.

    sched/mqueue:  Add internal function nxmq_send() and nxmq_timedsend() that are equivalent to mq_send() and mq_timedsend() except that they do not create cancellation points and do to not modify the errno variable.

sched/mqueue:  Rename all private static functions for use the nxmq_ vs. mq_ naming.

    sched/mqueue:  Rename all OS internal functions declared in sched/mqueue/mqueue.h to begin with nxmq_ vs. mq_.  The mq_ prefix is reserved for standard application interfaces.

8198ba6a6d This change renames all internal, private NuttX signal-related functions to use the prefix nxsig_ so that they cannot be confused with application interfaces that begin, primarily, with sig_
This is analogous to similar renaming that was done previously for semaphores.

Squashed commit of the following:

    sched/signal:  Fix a few compile warnings introduced by naming changes.

    sched/signal:  Rename all private, internal signl functions to use the nxsig_ prefix.

    sched/signal:  Rename sig_removependingsignal, sig_unmaskpendingsignal, and sig_mqnotempty to nxsig_remove_pendingsignal, nxsig_unmask_pendingsignal, and nxsig_mqnotempty to make it clear that these are OS internal interfaces.

    sched/signal:  Rename sig_findaction and sig_lowest to nxsig_find_action and nxsig_lowest to make it clear that these are OS internal interfaces.

    sched/signal:  Rename sig_allocatepingsigaction and sig_deliver to nxsig_alloc_pendingsigaction and nxsig_deliver to make it clear that these are OS internal interfaces.

    sched/signal:  Rename sig_cleanup, sig_release, sig_releasependingaction, and sig_releasependingsignal to nxsig_cleanup, nxsig_release, nxsig_release_pendingaction, and nxsig_release_pendingsignal to make it clear that these are OS internal interfaces.

    sched/signal:  Rename sig_tcbdispatch and sig_dispatch to nxsig_tcbdispatch and nxsig_dispatch to make it clear that these are OS internal interfaces.

    sched/signal:  Rename sig_releaseaction and sig_pendingset to nxsig_release_action and nxsig_pendingset to make it clear that these are OS internal interfaces.

    sched/signal:  Rename sig_initialize and sig_allocateactionblock to nxsig_initialize and nxsig_alloc_actionblock to make it clear that these are OS internal interfaces.

dca77fa06a sigtimedwait: When timer expires, up_unblock_task() is called. This is okay in the single CPU case because interrupts are disable in the timer interrupt handler. But it is insufficient in the SMP case. enter_ and leave_critical_section() must be called in order to manage spinlocks correctly. 2017-02-24 10:07:23 -06:00
