Enables pthread_mutexattr_settype(). # CONFIG_PRIORITY_INHERITANCE : Set to enable support for priority # inheritance on mutexes and semaphores. # CONFIG_SEM_PREALLOCHOLDERS: This setting is only used if priority # inheritance is enabled.

This value may be set # to zero if no more than one thread is expected to wait for # a semaphore. # CONFIG_FDCLONE_DISABLE. Disable cloning of all file descriptors # by task_create() when a new task is started. If set, all # files/drivers will appear to be closed in the new task. # CONFIG_FDCLONE_STDIO.

Create a dedicated "worker" thread to # handle delayed processing from interrupt handlers. This feature # is required for some drivers but, if there are not complaints, # can be safely disabled. The worker thread also performs # garbage collection -- completing any delayed memory deallocations # from interrupt handlers. If the worker thread is disabled, # then that clean will be performed by the IDLE thread instead # (which runs at the lowest of priority and may not be appropriate # if memory reclamation is of high priority). If CONFIG_SCHED_WORKQUEUE # is enabled, then the following options can also be used: # CONFIG_SCHED_WORKPRIORITY - The execution priority of the worker # thread. Default: 50 # CONFIG_SCHED_WORKPERIOD - How often the worker thread checks for # work in units of microseconds. Default: 50*1000 (50 MS). # CONFIG_SCHED_WORKSTACKSIZE - The stack size allocated for the worker # thread. Default: CONFIG_IDLETHREAD_STACKSIZE. # CONFIG_SIG_SIGWORK - The signal number that will be used to wake-up # the worker thread.

This must # be a value supported by the processor's memory management unit. # CONFIG_PAGING_NLOCKED - This is the number of locked pages in the # memory map. The locked address region will then be from # CONFIG_DRAM_VSTART through (CONFIG_DRAM_VSTART + # CONFIG_PAGING_PAGESIZE*CONFIG_PAGING_NLOCKED) # CONFIG_PAGING_LOCKED_PBASE and CONFIG_PAGING_LOCKED_VBASE - These # may be defined to determine the base address of the locked page # regions. If neither are defined, the logic will be set the bases # to CONFIG_DRAM_START and CONFIG_DRAM_VSTART (i.e., it assumes # that the base address of the locked region is at the beginning # of RAM). # NOTE: In some architectures, it may be necessary to take some # memory from the beginning of this region for vectors or for a # page table. In such cases, CONFIG_PAGING_LOCKED_P/VBASE should # take that into consideration to prevent overlapping the locked # memory region and the system data at the beginning of SRAM. # CONFIG_PAGING_NPPAGED - This is the number of physical pages # available to support the paged text region. This paged region # begins at (CONFIG_PAGING_LOCKED_PBASE + CONFIG_PAGING_PAGESIZE*CONFIG_PAGING_NPPAGED) # and continues until (CONFIG_PAGING_LOCKED_PBASE + CONFIG_PAGING_PAGESIZE*(CONFIG_PAGING_NLOCKED + # CONFIG_PAGING_NPPAGED) # CONFIG_PAGING_NVPAGED - This actual size of the paged text region # (in pages). This is also the number of virtual pages required to # support the entire paged region. The on-demand paging feature is # intended to support only the case where the virtual paged text # area is much larger the available physical pages. Otherwise, why # would you enable on-demand paging? # CONFIG_PAGING_NDATA - This is the number of data pages in the memory # map. The data region will extend to the end of RAM unless overridden # by a setting in the configuration file. # NOTE: In some architectures, it may be necessary to take some memory # from the end of RAM for page tables or other system usage. The # configuration settings and linker directives must be cognizant of that: # CONFIG_PAGING_NDATA should be defined to prevent the data region from # extending all the way to the end of memory. # CONFIG_PAGING_DEFPRIO - The default, minimum priority of the page fill # worker thread. The priority of the page fill work thread will be boosted # boosted dynmically so that it matches the priority of the task on behalf # of which it peforms the fill. This defines the minimum priority that # will be used. Default: 50. # CONFIG_PAGING_STACKSIZE - Defines the size of the allocated stack # for the page fill worker thread. Default: 1024. # CONFIG_PAGING_BLOCKINGFILL - The architecture specific up_fillpage() # function may be blocking or non-blocking. If defined, this setting # indicates that the up_fillpage() implementation will block until the # transfer is completed. Default: Undefined (non-blocking). # CONFIG_PAGING_WORKPERIOD - The page fill worker thread will wake periodically # even if there is no mapping to do. This selection controls that wake-up # period (in microseconds). This wake-up a failsafe that will handle any # cases where a single is lost (that would really be a bug and shouldn't # happen!) and also supports timeouts for case of non-blocking, asynchronous # fills (see CONFIG_PAGING_TIMEOUT_TICKS). # CONFIG_PAGING_TIMEOUT_TICKS - If defined, the implementation will monitor # the (asynchronous) page fill logic. If the fill takes longer than this # number if microseconds, then a fatal error will be declared. # Default: No timeouts monitored. # # Some architecture-specific settings. Defaults are architecture specific. # If you don't know what you are doing, it is best to leave these undefined # and try the system defaults: # # CONFIG_PAGING_VECPPAGE - This the physical address of the page in # memory to be mapped to the vector address. # CONFIG_PAGING_VECL2PADDR - This is the physical address of the L2 # page table entry to use for the vector mapping. # CONFIG_PAGING_VECL2VADDR - This is the virtual address of the L2 # page table entry to use for the vector mapping. # CONFIG_PAGING_BINPATH - If CONFIG_PAGING_BINPATH is defined, then it # is the full path to a file on a mounted file system that contains # a binary image of the NuttX executable. Pages will be filled by # reading from offsets into this file that correspond to virtual # fault addresses. # CONFIG_PAGING_MOUNTPT - If CONFIG_PAGING_BINPATH is defined, additional # options may be provided to control the initialization of underlying # devices. CONFIG_PAGING_MOUNTPT identifies the mountpoint to be used # if a device is mounted. # CONFIG_PAGING_MINOR - Some mount operations require a "minor" number # to identify the specific device instance. Default: 0 # CONFIG_PAGING_SDSLOT - If CONFIG_PAGING_BINPATH is defined, additional # options may be provided to control the initialization of underlying # devices. CONFIG_PAGING_SDSLOT identifies the slot number of the SD # device to initialize. This must be undefined if SD is not being used. # This should be defined to be zero for the typical device that has # only a single slot (See CONFIG_MMCSD_NSLOTS). If defined, # CONFIG_PAGING_SDSLOT will instruct certain board-specific logic to # initialize the media in this SD slot. # CONFIG_PAGING_M25PX - Use the m25px.c FLASH driver. If this is selected, # then the MTD interface to the M25Px device will be used to support # paging. # CONFIG_PAGING_M25PX_BINOFFSET - If CONFIG_PAGING_M25PX is defined then # CONFIG_PAGING_M25PX_BINOFFSET will be used to specify the offset # in bytes into the FLASH device where the NuttX binary image is located. # Default: 0 # CONFIG_PAGING_M25PX_SPIPORT - If CONFIG_PAGING_M25PX is defined and # the device has multiple SPI busses (ports), then this configuration # should be set to indicate which SPI port the M25Px device is connected. # Default: 0 # CONFIG_PAGING=y CONFIG_PAGING_PAGESIZE=1024 CONFIG_PAGING_NLOCKED=48 #CONFIG_PAGING_LOCKED_PBASE #CONFIG_PAGING_LOCKED_VBASE CONFIG_PAGING_NPPAGED=96 CONFIG_PAGING_NVPAGED=384 CONFIG_PAGING_NDATA=32 #CONFIG_PAGING_DEFPRIO CONFIG_PAGING_STACKSIZE=2048 CONFIG_PAGING_BLOCKINGFILL=y #CONFIG_PAGING_WORKPERIOD #CONFIG_PAGING_TIMEOUT_TICKS #CONFIG_PAGING_VECPPAGE #CONFIG_PAGING_VECL2PADDR #CONFIG_PAGING_VECL2VADDR #CONFIG_PAGING_BINPATH="/mnt/pgsrc/nuttx.bin" CONFIG_PAGING_MOUNTPT="/mnt/pgsrc" CONFIG_PAGING_MINOR=0 CONFIG_PAGING_SDSLOT=0 CONFIG_PAGING_M25PX=n CONFIG_PAGING_M25PX_BINOFFSET=0 CONFIG_PAGING_M25PX_SPIPORT=0 # # The following can be used to disable categories of # APIs supported by the OS.
