e24f281401 This commit adds a new internal interfaces and fixes a problem with three APIs in the SMP configuration. The new internal interface is sched_cpu_pause(tcb). This function will pause a CPU if the task associated with 'tcb' is running on that CPU. This allows a different CPU to modify that OS data stuctures associated with the CPU. When the other CPU is resumed, those modifications can safely take place. 
The three fixes are to handle cases in the SMP configuration where one CPU does need to make modifications to TCB and data structures on a task that could be running running on another CPU.  Those three cases are task_delete(), task_restart(), and execution of signal handles.  In all three cases the solutions is basically the same:  (1) Call sched_cpu_pause(tcb) to pause the CPU on which the task is running, (2) perform the necessary operations, then (3) call up_cpu_resume() to restart the paused CPU.

5f9ee79298 I/O Expander: Remove hard-coded PCA9555 fields from ioexpander.h definitons. Add support for an attach() method that may be used when any subset of pin interrupts occur. 
PCA9555 Driver:  Replace the signalling logic with a simple callback using the new definitons of ioexpander.h.  This repartitioning of functionality is necessary because (1) the I/O expander driver is the lower-lower part of any driver that uses GPIOs (include the GPIO driver itself) and should not be interacting directly with the much higher level application layer.  And (2) in order to be compatible with the GPIO driver (and any arbitrary upper half driver), the PCA9555 should not directly signal, but should call back into the upper half.  The upper half driver that interacts directly with the application is the appropriate place to be generating signal.

52fbbaf778 1. SMP: Fix an assertion. SMP-specific change accidentally made in non-SMP code 
2. Move list of signal actions from the task TCB to the task group.  Signal handlers are a property of the entire task group and not of individual threads in the group.  I know, I preferred it the other way too but this is more compliant with POSIX.

2a93c66948 include/nuttx/net/netdev.h and several Ethernet drivers in arch/: Most network drivers to not support statistics. Those that do only support them when DEBUG is enabled. Each driver collects an architecture specific set of statistics and there is no mechanism in place to view those statistics. Thus, the driver feature was mostly useless. This change standardizes the driver statistics and puts the definition in the common network device structure defined in netdev.h where they can be accessed by network applications. All Ethernet drivers that collect statistics have been adapted to use these common statistics. 2015-11-26 12:08:09 -06:00

5ac6de118e libc/math/lib_asin.c: The function did not convert for some input values. Asin did not convert for values which do not belong to the domain of the function. But aside of that the function also did not convert for sine allowed values. I achieved a conversion of the function by reducing the DBL_EPSION and by checking if the input value is in the domain of the function. This is a fix for the problem but the function should always terminate after a given number of iterations. From Stefan Kolb. 2015-09-01 08:45:14 -06:00
