Gregory Nutt 0f97d81f8d Completes the implemenation of the core shared memory logic: shmget(), shmctl(), shmat(), and shmdt(). This is still some unfinish platform-specific code that needs to be done before we can begin testing. 2014-09-23 16:07:12 -06:00

Gregory Nutt ee0d20d44c Add interfaces to support un-initializing a granule allocator. 2014-09-23 16:05:32 -06:00
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
