The SIGADDSET() macro adds signo to set. No effort is made to ensure that signo is a valid signal number. The SIGDELSET() macro removes signo from set. No effort is made to ensure that signo is a vali...
These functions post a signal to one or more processes. The argument signum common to all three functions should be in the range [1-NSIG]. The psignal() function posts signal number signum to the proc...
The physio() is a helper function typically called from character device read() and write() routines to start I/O on a user process buffer. The maximum amount of data to transfer with each call is det...
The pmap module is the machine-dependent portion of the FreeBSD VM (Virtual Memory) sub-system. Each function documented herein must have its own architecture-dependent implementation. The pmap module...
The pmap_activate() function activates the physical map for a user thread td. This function must be called before the thread's address space may be accessed.
The pmap_change_wiring() function changes the wiring attribute for the page at virtual address va in the physical map pmap. A wired page gets its name from being `wired' into the system page tables s...
The pmap_clear_modify() function clears the `modified' bit on the physical page m. The pmap_clear_reference() function clears the `referenced' bit on the physical page m.
The pmap_clear_modify() function clears the `modified' bit on the physical page m. The pmap_clear_reference() function clears the `referenced' bit on the physical page m.
The pmap_copy() function copies the range specified by src_addr and len from the source physical map src_pmap to the destination physical map dst_pmap at the address dst_addr. The pmap_copy_page() fun...
The pmap_copy() function copies the range specified by src_addr and len from the source physical map src_pmap to the destination physical map dst_pmap at the address dst_addr. The pmap_copy_page() fun...
The pmap_enter() function inserts the given physical page p, into the physical map pmap, at the virtual address va, with the protection prot. If wired is TRUE, then increment the wired count for the p...
The pmap_extract() function maps a virtual address to a physical page. In certain situations, callers may use pmap_extract_and_hold() instead, to ensure that the returned page is held. The pmap_extrac...
