Gregory Nutt 4f5879f998 C library: Add ffs(). Add strings.h. Move strcasecmp, strncasecmp, bzero, bcmp, and bcopy to where they belong in strings.h.h, not string.h. bzero, bcmp, and bcopy are legacy functions; the contemporary counterparts should be used instead. 2017-02-16 16:10:09 -06:00

Gregory Nutt 13cac3b592 sched/: Change some *err() message to *info() messages if what was a *dbg() message does not indicate and error condition. 2016-06-11 16:42:42 -06:00

Gregory Nutt 80d0b2736e Reorder some logic: (1) set initial CPU IDLE task regsters AFTER allocating stack, (2) invalidate cache in CPU start-up BEFORE handling first interrupt. 2016-05-22 15:01:49 -06:00
Gregory Nutt 32838fcc2c enter/leave_critical_section: In SMP configuration, may attempt to access the task lists before they have been initialized 2016-05-18 09:17:01 -06:00

Gregory Nutt a633353ec3 Add a CPU affinity set to the TCB if SMP is enable and use this CPU set as a mask for determining which CPUs the thread may run on. Add an affinity field to the attrributes to permit controlling which CPUs a pthread may run on. Implements pthread_att_setaffinity_np() and pthread_attr_getaffinity_np(). 2016-02-19 17:33:35 -06:00

Gregory Nutt 6aeb4a52e8 Performance improvement: Idle loop should not take MM semaphore if there is not garbage to be collected. This can cause loss of performance and thrashing in tasking 2016-02-16 19:33:22 -06:00
Gregory Nutt 6dfa72d038 SMP: Fix some dumb but difficult to debug errors 2016-02-16 16:43:19 -06:00

Gregory Nutt 7d7f4e140c OS: Add a RUNNABLE attribute to the tasklists to indicate if the task list includes the currently executing task. Use this additional bit of information to determine if a context switch could really occur when removing a TCB from a task list 2016-02-12 08:15:16 -06:00
Gregory Nutt c315479a04 SMP: Move IDLE thread init logic from sim to OS; need to assign unique IDs to each IDLE task 2016-02-11 14:11:26 -06:00

Gregory Nutt 47a5663f8c SMP: A few preliminary data structure definitions 2016-02-10 11:45:26 -06:00
Gregory Nutt 2dc258986d Add a state variable that provides the current level of OS initialization. This is needed by some logic that may attempt to run early in the start-up sequence, but cannot run if a sufficient level of initializaitn has not not yet occurred 2016-02-05 08:34:03 -06:00
Gregory Nutt 79d554939e sched/: Fix some spacing issues 2015-10-07 19:59:14 -06:00
Gregory Nutt cb9e27c3b0 Standardize naming used for public data and function groupings 2015-10-02 16:30:35 -06:00
Gregory Nutt d78d3ef4ab Logic for delayed memory garbage collection for the case of user space memory will not work as implemented for the case of the kernel build. That is because the correct context is in place in order to free the user memory when sched_kufree is called, but will not be in place later when the memory garbage collection runs. If this feature is really needed, then some more substantial redesign is required 2015-09-07 14:40:18 -06:00
Gregory Nutt 12d61531aa Move board_ prototypes from arch.h to board.h 2015-02-27 20:02:03 -06:00
Gregory Nutt 8840102554 Networking: Divide net_intiialize() into net_setup() and net_initialize() to solve a chicken-and-egg problem. net_setup() must be caleld before up_initialize() is called so that networking data structures are ready to register new network devices. 
net_initialize() now does only timer related operations and is called AFTER up_initialize() where the timers are configured.  This is really.

Gregory Nutt 0fcd620404 Move the initialization of the networking subsystem to AFTER up_initialize is called. Fromo Macs Neklyudov. 2015-02-13 13:41:21 -06:00
Gregory Nutt 937f9f23f1 strncpy will not copy the terminating \0 into the destination if the source is larger than the size of the destination. Ensure that the last byte is always zero and let strncpy only copy CONFIG_TASK_NAME_SIZE bytes. The issue of unterminated names can be observed in ps when creating a pthread while CONFIG_TASK_NAME_SIZE is set to 8. 2014-12-17 12:24:02 -06:00
