d38be46655 sched/irq: Add support interrupt chains in NuttX. IRQ chain is very useful in these cases: (1) Multiple hardware connect to the same request line(e.g. PCI), (2) Need multiple driver to support one hardware block (like Linux MFD) 2018-08-24 15:10:23 -06:00

6150299f54 Merged in masayuki2009/nuttx.nuttx/irq_spinlock (pull request #550) 
SMP: Introduce spin_lock_irqsave() and spin_unlock_irqrestore()

These APIs are simplified version of enter_critical_section() and
leave_critical_section() to protect data (e.g. registers) in SMP mode.
By using these APIs inside drivers, performace will be improved.

sched/semaphore:  Add nxsem_post() which is identical to sem_post() except that it never modifies the errno variable.  Changed all references to sem_post in the OS to nxsem_post().

    sched/semaphore:  Add nxsem_destroy() which is identical to sem_destroy() except that it never modifies the errno variable.  Changed all references to sem_destroy() in the OS to nxsem_destroy().

    libc/semaphore and sched/semaphore:  Add nxsem_getprotocol() and nxsem_setprotocola which are identical to sem_getprotocol() and set_setprotocol() except that they never modifies the errno variable.  Changed all references to sem_setprotocol in the OS to nxsem_setprotocol().  sem_getprotocol() was not used in the OS

c9661ad5a7 Change all time conversions. Yech. New timer units in microseconds breaks all existing logic that used milliseconds in the conversions.
