baf79de7e5 task: assign_pid retry after malloc
Calling malloc in the critical section may cause thread switching.
Add a retry mechanism to handle the situation where other threads have been successfully expanded.

8a8c1f943e sched/tcb: use shared group for kthreads
Kthreads can share the group data so that to reduce overheads.
This implements shared kthread group via:

- use `tcb_s` instead of `task_tcb_s` for kthreads
- use `g_kthread_group` when creating kthreads
- use stackargs to start tasks and kthreads

see pull/12320 for test logs.

0dedbcd4ae task/pthread_cancelpt: Move cancel point handling to libc, data to TLS
This moves task / thread cancel point logic from the NuttX kernel into
libc, while the data needed by the cancel point logic is moved to TLS.

The change is an enabler to move user-space APIs to libc as well, for
a coherent user/kernel separation.

e277ac7a7f sched: task: Fix a potential bug in nxtask_assign_pid()
Summary:
- During reviewing sched_lock() in nxtask_assign_pid(),
  I noticed that g_pidhash is not protected by a critical section
- Because g_pidhash is accessed in an interrupt context,
  it should be protected by a critical section.
- Actually, nxsched_foreach(), nxsched_get_tcb() and so on
  use a critical section.

Impact:
- No impact

Testing:
- Tested with spresense:wifi (non-SMP) and spresense:wifi_smp

44b8f3e467 include/nuttx/sched.h: Move prototype for sched_releasetcb()
Move the prototype for the internal OS from from sched/sched/sched.h to include/nuttx/sched.h.  This was done because binfmt/binfmt/excecmodule.c requires the prototype for sched_releasetcb() and was illegally including sched/sched/sched.h.  That is a blatant violation of the OS modular design and the person that did this should be hung up by their thumbs.  Oh... I did that back in a bad moment in 2014.  Now that is made right.

8e321aba84 sched/: Correct some naming. The NuttX task groups have been using the acroynum 'gid' and also the type 'gid_t' for the the task group ID. That is incorrect. Than naming is reserved for use with group permissions. So these were all named to grpid and grpid_t so that it is clearer that these refer to NuttX task group IDs, and not to group permissions. 2019-08-02 10:01:30 -06:00
