Abdelatif Guettouche 20d34cce98 sched/irq_section.c: irq_waitlock is a private function; remove its
prototype from irq.h and define it as static.

Xiang Xiao 001e7c3e76 sched: Don't include nuttx/sched.h inside sched.h
But let nuttx/sched.h include sched.h instead to
avoid expose nuttx kernel API to userspace.

Masayuki Ishikawa d87f350831 arch, boards, drivers, include, sched, wireless: Change spinlock APIs.
Summary:
- This commit changes spinlock APIs (spin_lock_irqsave/spin_unlock_irqrestore)
- In the previous implementation, the global spinlock (i.e. g_irq_spin) was used.
- This commit allows to use caller specific spinlock but also supports to use
  g_irq_spin for backword compatibility (In this case, NULL must be specified)

Impact:
- None

Testing:
- Tested with the following configurations
- spresnse:wifi, spresense:wifi_smp
- esp32-devkitc:smp (QEMU), sabre6-quad:smp (QEMU)
- maxi-bit:smp (QEMU), sim:smp
- stm32f4discovery:wifi

Masayuki Ishikawa 08c4376606 arch, include, sched : Refactor ARCH_GLOBAL_IRQDISABLE related code
Summary:
- ARCH_GLOBAL_IRQDISABLE was initially introduced for LC823450 SMP
- At that time, i.MX6 (quad Cortex-A9) did not use this config
- However, this option is now used for all CPUs which support SMP
- So it's good timing for refactoring the code

Impact:
- Should have no impact because the logic is the same for SMP

Testing:
- Tested with board: spresense:smp, spresense:wifi_smp
- Tested with qemu: esp32-core:smp, maix-bit:smp, sabre-6quad:smp
- Build only: lc823450-xgevk:rndis, sam4cmp-db:nsh

Gregory Nutt fc6084f311 Squashed commit of the following:
fs/procfs/fs_procfsproc:  Extended the process ID ProcFS output to show per-thread maximum time for pre-emption disabled and maximum time within a critical section.

    sched/sched/sched_critmonitor.c:  Adds data collection logic in support of monitoring critical sections and pre-emption state.

zhuguangqing 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

Masayuki Ishikawa 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.
