Gregory Nutt 835c91b03a Add support for a per-process virtual page allocator. This is a new member 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. 2014-09-23 16:04:39 -06:00
Gregory Nutt 398f7b594f execv() is a basic system interface. It should not be in libc/ but rather in sched/task. Its symboltable helper logic also belongs in the kernel but belings in binfmt/ with the other symbol table logic 2014-09-15 10:15:47 -06:00
Gregory Nutt 62880f60c4 In kernel mode, we have to duplicate the callers argv[] buffer when exec'ing new tasks. When the argv[] buffer is needed, the caller's address environment will not longer be in place 2014-09-14 14:10:23 -06:00
Gregory Nutt 2eb71d5a35 Fix an ordering problem in integration of kernel stack logic 2014-09-14 12:40:09 -06:00

Gregory Nutt 0fc55d042f Misc fixes to repair some of the breakage to the SAMA5D4-EK elf configuration caused by changes for the knsh configuration 2014-09-11 10:31:12 -06:00
Gregory Nutt 205c23b9d6 Add logic to initialize the per-process user heap when each user process is started 2014-09-10 15:55:36 -06:00
Gregory Nutt df4682fd1f Add configuration to use the fixed DRAM mapping for the page pool (if 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. 2014-09-10 08:41:01 -06:00
Gregory Nutt 76957599a2 When allocating a stack for a new process using the user-sapce allocator, need to select the address environment first 2014-09-09 17:32:32 -06:00
Gregory Nutt 23147c40a5 Remove final traces of the 8015 from the NuttX source tree 2014-09-01 13:21:15 -06:00

Gregory Nutt 89593969be nuttx/sched: Remove explicit references to errno. That is a problem from within the kernel for certain configurations 2014-08-28 17:00:43 -06:00
Gregory Nutt ad53cabf34 ADDRENV: Use a group flag to determine if there is an address environment (instead of the thread type) 2014-08-27 09:37:28 -06:00
Gregory Nutt b13d9b4161 Rename up_addrenv_assign() to up_addrenv_clone() and generalize its arguments so that can be used for other purposes 2014-08-26 12:16:05 -06:00
Gregory Nutt 241a7e17bd addrenv interface changes: up_addrenv_create() may need to create .text and .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(). 2014-08-24 11:54:14 -06:00
Gregory Nutt 1624e2fbcf Change CONFIG_ADDRENV to CONFIG_ARCH_ADDRENV; change how it is selected -- the architecure must first declare support 2014-08-24 06:42:11 -06:00
