2015-07-09Allow non-privileged tasks to wire 64KiB task memorySamuel Thibault
* doc/mach.texi (vm_wire): Document that the host port does not have to be privileged. * include/mach/mach_hosts.defs (vm_wire): Use mach_port_t instead of host_priv_t. * vm/vm_map.h (vm_map): Add user_wired field. * vm/vm_map.c (vm_map_setup): Initialize user_wired field to 0. (vm_map_pageable_common, vm_map_entry_delete, vm_map_copy_overwrite, vm_map_copyout_page_list, vm_map_copyin_page_list): When switching user_wired_count field of entry between 0 and non-0, accumulate the corresponding size into the user_wired field of map. * vm/vm_user.c (vm_wire): Turn host parameter into port parameter, and inline a version of convert_port_to_host_priv which records whether the host port is privileged or not. When it is not privileged, check whether the additional amount to user_wired will overcome 64KiB.
2014-11-10Revert "Make vm_map really ignore `address' when `anywhere' is true"Samuel Thibault
This reverts commit 5ae510e35c54009626999a88f0f1cb34d6dfc94f.
2014-09-06Make vm_map really ignore `address' when `anywhere' is trueSamuel Thibault
As vm_allocate does. * vm/vm_user.c (vm_map): When `anywhere' is true, set `address' to the minimum address of the `target_map'.
