* drivers/ramdisk.c and include/nuttx/fs/ramdisk.h: Add logic to dispose of ↵Gregory Nutt2015-02-011-1/+1
| | | | the drvier and RAM buffer when the RAM disk has been unlinked and all open references to the RAM disk have been closed. Add new parameters to romdisk() to specify what should be done with the RAM/ROM buffer -- Should it be freed or not? Changed all calls to ramdisk() to use these new parameters.

* Add support for a per-process virtual page allocator. This is a new member ↵Gregory Nutt2014-09-231-1/+14
| | | | of the task_group_s structure. The allocaor must be initialized when a new user process is started and uninitialize when the process group is finally destroyed. It is used by shmat() and shmdt() to pick the virtual address onto which to map the shared physical memory.
* execv() is a basic system interface. It should not be in libc/ but rather ↵Gregory Nutt2014-09-151-2/+6
| | | | in sched/task. Its symboltable helper logic also belongs in the kernel but belings in binfmt/ with the other symbol table logic

* In kernel mode, we have to duplicate the callers argv[] buffer when exec'ing ↵Gregory Nutt2014-09-144-14/+173

* Add configuration to use the fixed DRAM mapping for the page pool (if ↵Gregory Nutt2014-09-101-2/+7
| | | | available) instead of remapping dynamically to access L2 page tables and page data. Also, add logic in address environment creation to initialize the shared data at the beginning of the .bss/.data process memory region.
* When allocating a stack for a new process using the user-sapce allocator, ↵Gregory Nutt2014-09-092-6/+32

* ELF relocations. Some relocation types do not have a named symbol ↵Gregory Nutt2014-09-093-7/+51

* ADDRENV: Use a group flag to determine if there is an address environment ↵Gregory Nutt2014-08-271-0/+4

* Add up_addrenv_coherent which will be called before address environment switchesGregory Nutt2014-08-261-2/+15

* Can't dump loaded code unless we first establish the mappingsGregory Nutt2014-08-261-4/+47

* Change when address environment is instantiated; there are/were locations ↵Gregory Nutt2014-08-262-73/+80

* addrenv interface changes: up_addrenv_create() may need to create .text and ↵Gregory Nutt2014-08-249-67/+120
| | | | .bss/.data separately because of differing access privileges (read/execute vs read/write). And, as a consequence, up_addrenv_vaddr() needs to be split into up_addrenv_vtext(0 and up_addrenv_vdata().
* Add addrenv.h; First cut at Cortex-A address environment structures; Add ↵Gregory Nutt2014-08-242-2/+2
