From b10112ec96516939dc3cb5d523807fda2755fb37 Mon Sep 17 00:00:00 2001 From: Thomas Schwinge Date: Sat, 5 May 2007 00:30:31 +0000 Subject: 2007-05-05 Thomas Schwinge We're not in the eighties anymore. List arguments in function prototypes and definitions for a lot of symbols. Also drop some unused prototypes. I refrain from listing every changed symbol. * vm/memory_object.c: Do as described. * vm/memory_object.h: Likewise. * vm/pmap.h: Likewise. * vm/vm_external.c: Likewise. * vm/vm_external.h: Likewise. * vm/vm_fault.c: Likewise. * vm/vm_fault.h: Likewise. * vm/vm_kern.h: Likewise. * vm/vm_map.c: Likewise. * vm/vm_map.h: Likewise. * vm/vm_pageout.h: Likewise. * vm/vm_user.h: Likewise. * vm/memory_object.h: Include . * vm/pmap.h: Include . * vm/vm_fault.h: Include , and . * vm/vm_map.h: Include and . (vm_map_t, VM_MAP_NULL): Remove type and definition. * vm/vm_object.h (vm_object_t, VM_OBJECT_NULL): Remove type and definition. * vm/vm_page.h: Include . (vm_page_t, VM_PAGE_NULL): Remove type and definition. * vm/vm_user.h: Include . * kern/task.h: Include instead of . * vm/vm_types.h: New file: the above-removed types and definitions. --- vm/pmap.h | 97 ++++++++++++++++++++++++--------------------------------------- 1 file changed, 37 insertions(+), 60 deletions(-) (limited to 'vm/pmap.h') diff --git a/vm/pmap.h b/vm/pmap.h index 98ef5ba..04ab4e9 100644 --- a/vm/pmap.h +++ b/vm/pmap.h @@ -42,6 +42,7 @@ #include #include #include +#include /* * The following is a description of the interface to the @@ -62,21 +63,15 @@ * but it is not part of the interface. */ -extern vm_offset_t pmap_steal_memory(); /* During VM initialization, - * steal a chunk of memory. - */ -extern unsigned int pmap_free_pages(); /* During VM initialization, - * report remaining unused - * physical pages. - */ -extern void pmap_startup(); /* During VM initialization, - * use remaining physical pages - * to allocate page frames. - */ -extern void pmap_init(); /* Initialization, - * after kernel runs - * in virtual memory. - */ +/* During VM initialization, steal a chunk of memory. */ +extern vm_offset_t pmap_steal_memory(vm_size_t); +/* During VM initialization, report remaining unused physical pages. */ +extern unsigned int pmap_free_pages(void); +/* During VM initialization, use remaining physical pages to allocate page + * frames. */ +extern void pmap_startup(vm_offset_t *, vm_offset_t *); +/* Initialization, after kernel runs in virtual memory. */ +extern void pmap_init(void); #ifndef MACHINE_PAGES /* @@ -95,14 +90,10 @@ extern void pmap_init(); /* Initialization, * However, for best performance pmap_free_pages should be accurate. */ -extern boolean_t pmap_next_page(); /* During VM initialization, - * return the next unused - * physical page. - */ -extern void pmap_virtual_space(); /* During VM initialization, - * report virtual space - * available for the kernel. - */ +/* During VM initialization, return the next unused physical page. */ +extern boolean_t pmap_next_page(vm_offset_t *); +/* During VM initialization, report virtual space available for the kernel. */ +extern void pmap_virtual_space(vm_offset_t *, vm_offset_t *); #endif /* MACHINE_PAGES */ /* @@ -139,12 +130,10 @@ void pmap_protect(pmap_t pmap, vm_offset_t sva, vm_offset_t eva, vm_prot_t prot) /* * Routines to set up hardware state for physical maps to be used. */ -extern void pmap_activate(); /* Prepare pmap_t to run - * on a given processor. - */ -extern void pmap_deactivate(); /* Release pmap_t from - * use on processor. - */ +/* Prepare pmap_t to run on a given processor. */ +extern void pmap_activate(pmap_t, thread_t, int); +/* Release pmap_t from use on processor. */ +extern void pmap_deactivate(pmap_t, thread_t, int); /* @@ -178,7 +167,6 @@ boolean_t pmap_is_modified(vm_offset_t pa); /* * Statistics routines */ -extern void pmap_statistics(); /* Return statistics */ #ifndef pmap_resident_count extern int pmap_resident_count(); @@ -187,48 +175,37 @@ extern int pmap_resident_count(); /* * Sundry required routines */ -extern vm_offset_t pmap_extract(); /* Return a virtual-to-physical - * mapping, if possible. - */ - -extern boolean_t pmap_access(); /* Is virtual address valid? */ - -extern void pmap_collect(); /* Perform garbage - * collection, if any - */ - -extern void pmap_change_wiring(); /* Specify pageability */ +/* Return a virtual-to-physical mapping, if possible. */ +extern vm_offset_t pmap_extract(pmap_t, vm_offset_t); +/* Is virtual address valid? */ +extern boolean_t pmap_access(); +/* Perform garbage collection, if any. */ +extern void pmap_collect(pmap_t); +/* Specify pageability. */ +extern void pmap_change_wiring(pmap_t, vm_offset_t, boolean_t); #ifndef pmap_phys_address -extern vm_offset_t pmap_phys_address(); /* Transform address - * returned by device - * driver mapping function - * to physical address - * known to this module. - */ +/* Transform address returned by device driver mapping function to physical + * address known to this module. */ +extern vm_offset_t pmap_phys_address(); #endif /* pmap_phys_address */ #ifndef pmap_phys_to_frame -extern int pmap_phys_to_frame(); /* Inverse of - * pmap_phys_address, - * for use by device driver - * mapping function in - * machine-independent - * pseudo-devices. - */ +/* Inverse of pmap_phys_address, for use by device driver mapping function in + * machine-independent pseudo-devices. */ +extern int pmap_phys_to_frame(); #endif /* pmap_phys_to_frame */ /* * Optional routines */ #ifndef pmap_copy -extern void pmap_copy(); /* Copy range of - * mappings, if desired. - */ +/* Copy range of mappings, if desired. */ +extern void pmap_copy(pmap_t, pmap_t, vm_offset_t, vm_size_t, + vm_offset_t); #endif /* pmap_copy */ #ifndef pmap_attribute -extern kern_return_t pmap_attribute(); /* Get/Set special - * memory attributes - */ +/* Get/Set special memory attributes. */ +extern kern_return_t pmap_attribute(); #endif /* pmap_attribute */ /* -- cgit v1.2.3
