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

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

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

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

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
