82acf6e6a7 irq: All irq_cpu_locked is called in the critical_section, and the parameter is the current cpu id. 
so it must return false, We can safely delete.

1b04bfae20 sched: Remove the unnecessary weak_function 
because not all compiler support the weak attribute, and
many features are either always used or guarded by config.

1b00e5d518 spinlock: Remove SP_SECTION 
Summary:
- SP_SECTION was introduced to allocate spinlock in non-cachable
  region mainly for Cortex-A to stabilize the NuttX SMP kernel
- However, all spinlocks are now allocated in cachable area and
  works without any problems
- So SP_SECTION should be removed to simplify the kernel code

Impact:
- None

Testing:
- Build test only

1ac9558460 sched/irq and sched/sched: Measurement of interrupt handler duration used to be available only in Tickless mode since it used the high resolution Tickless timer to measure interrupt time. This commit adds CONFIG_SCHED_IRQMONITOR_GETTIME which, if enabled, will force the interrupt duration caculation to use the same high-resolution, platform-specific timer as is used with the Critical Section Monitor. This leads to two improvements: (1) You can now measure interrupt duration in non-Tickless mode, and (2) in either mode, the interrupt duration and the critical section measures will use the same high-resulotion timer and should, therefore, never be any descripancy due to different clock sources. 2018-11-26 11:29:20 -06:00

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

c2b620b4f8 Implements support for smaller interrupt tables as described at http://www.nuttx.org/doku.php?id=wiki:howtos:smallvectors . This is largely the work of Mark Schulte. However, I have made several changes to match with the Wiki document. If you like the change, thanks go to Marc. For any errors you can blame me. 2017-03-03 09:20:25 -06:00

b3222bbc8a irq_dispatch: Add argument pointer to irq_dispatch 
Provide a user defined callback context for irq's, such that when
registering a callback users can provide a pointer that will get
passed back when the isr is called.
