2002-03-14First round of __P removal in sysTodd C. Miller
2001-12-19UBC was a disaster. It worked very good when it worked, but on someArtur Grabowski
machines or some configurations or in some phase of the moon (we actually don't know when or why) files disappeared. Since we've not been able to track down the problem in two weeks intense debugging and we need -current to be stable, back out everything to a state it had before UBC. We apologise for the inconvenience.
2001-12-04Yet another sync to NetBSD uvm.Artur Grabowski
Today we add a pmap argument to pmap_update() and allocate map entries for kernel_map from kmem_map instead of using the static entries. This should get rid of MAX_KMAPENT panics. Also some uvm_loan problems are fixed.
2001-11-28Sync in more uvm from NetBSD. Mostly just cosmetic stuff.Artur Grabowski
Contains also support for page coloring.
2001-11-28more sync to netbsd. some bugfixes in uvm_km_kmemalloc, lots of fixes in ↵Artur Grabowski
uvm_loan.
2001-11-28Sync in more uvm changes from NetBSD.Artur Grabowski
This time we're getting rid of KERN_* and VM_PAGER_* error codes and use errnos instead.
2001-11-10Move maxdmap and maxsmap to kern_resource.cArtur Grabowski
2001-11-07Another sync of uvm to NetBSD. Just minor fiddling, no major changes.Artur Grabowski
2001-11-06Let fork1, uvm_fork, and cpu_fork take a function/argument pair as argument,Artur Grabowski
instead of doing fork1, cpu_set_kpc. This lets us retire cpu_set_kpc and avoid a multiprocessor race. This commit breaks vax because it doesn't look like any other arch, someone working on vax might want to look at this and try to adapt the code to be more like the rest of the world. Idea and uvm parts from NetBSD.
2001-11-06More sync to NetBSD.Artur Grabowski
- Use malloc/free instead of MALLOC/FREE for variable sized allocations. - Move the memory inheritance code to sys/mman.h and rename from VM_* to MAP_* - various cleanups and simplifications.
2001-11-06Move the last content from vm/ to uvm/Artur Grabowski
The only thing left in vm/ are just dumb wrappers. vm/vm.h includes uvm/uvm_extern.h vm/pmap.h includes uvm/uvm_pmap.h vm/vm_page.h includes uvm/uvm_page.h
2001-11-05Minor sync to NetBSD.Artur Grabowski
2001-09-19merge vm/vm_kern.h into uvm/uvm_extern.h; art@ okMichael Shalayeff
2001-08-11Various random fixes from NetBSD.Artur Grabowski
Including support for zeroing pages in the idle loop (not enabled yet).
2001-08-06Add a new type voff_t (right now it's typedefed as off_t) used for offsetsArtur Grabowski
into objects. Gives the possibilty to mmap beyond the size of vaddr_t. From NetBSD.
2001-07-25Change the pmap_enter interface to merge access_type and the wired booleanArtur Grabowski
and arbitrary flags into one argument. One new flag is PMAP_CANFAIL that tells pmap_enter that it can fail if there are not enough resources to satisfy the request. If this flag is not passed, pmap_enter should panic as it should have done before this change (XXX - many pmaps are still not doing that). Only i386 and alpha implement CANFAIL for now. Includes uvm updates from NetBSD.
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.
