2001-06-23Sync with NetBSD 19990911 (just before PMAP_NEW was required)smart
- thread_sleep_msg() -> uvm_sleep() - initialize reference count lock in uvm_anon_{init,add}() - add uao_flush() - replace boolean 'islocked' with 'lockflags' - in uvm_fault() change FALSE to TRUE to in 'wide' fault handling - get rid of uvm_km_get() - various bug fixes
2001-06-08Change the paddr_t pmap_extract(struct pmap *, vaddr_t) interface toArtur Grabowski
boolean_t pmap_extract(struct pmap *, vaddr_t, paddr_t *). Matches NetBSD. Tested by various people on various platforms.
2001-05-07Few fixes from NetBSD.Artur Grabowski
- make sure that vsunlock doesn't unwire mlocked memory. - fix locking in uvm_useracc. - Return the error uvm_fault_wire in uvm_vslock (will be used soon).
2001-05-05PMAP_NEW and UVM are no longer optional on i386.Artur Grabowski
2001-05-05Remove the (vaddr_t) casts inside the round_page and trunc_page macros.Artur Grabowski
We might want to use them on types that are bigger than vaddr_t. Fix all callers that pass pointers without casts.
2001-04-03It is unnecessary to wrap uvm_wait() in splhigh(). Also, set p_addr to NULLAaron Campbell
when we free it; art@ ok
2001-04-02On popular demand, the Linux-compatibility clone(2) implementation basedNiklas Hallqvist
on NetBSD's code, as well as some faked Posix RT extensions by me. This makes at least simple linuxthreads tests work.

2000-09-07Convert bzero to memset(X, 0..) and bcopy to memcpy.Artur Grabowski
This is to match (make diffs smaller) the code in NetBSD. new gcc inlines those functions, so this could also be a performance win.
2000-03-16Bring in some new UVM code from NetBSD (not current).Artur Grabowski
- Introduce a new type of map that are interrupt safe and never allow faults in them. mb_map and kmem_map are made intrsafe. - Add "access protection" to uvm_vslock (to be passed down to uvm_fault and later to pmap_enter). - madvise(2) now works. - various cleanups.
2000-03-01Prepare for new pmapNiklas Hallqvist
1999-09-03Change the pmap_enter api to pass down an argument that indicatesArtur Grabowski
the access type that caused this mapping. This is to simplify pmaps with mod/ref emulation (none for the moment) and in some cases speed up pmap_is_{referenced,modified}. At the same time, clean up some mappings that had too high protection. XXX - the access type is incorrect in old vm, it's only used by uvm and MD code. The actual use of this in pmap_enter implementations is not in this commit.
1999-08-23sync with NetBSD from 1999.05.24 (there is a reason for this date)Artur Grabowski
Mostly cleanups, but also a few improvements to pagedaemon for better handling of low memory and/or low swap conditions.
1999-08-17New cpu_fork API to take a stack in which you point the child's stackpointerNiklas Hallqvist
to, at the bottom or the top, depending on your architecture's stack growth direction. This is in preparation for Linux' clone(2) emulation. port maintainers, please check that I did the work right.
