2001-05-16No need to check M_WAIT/M_WAITOK malloc return values. (art@ ok)Hakan Olsson
2001-05-10More sync to NetBSD.Artur Grabowski
The highlight is some more advices to madvise(2). o MADV_DONTNEED will deactive the pages in the given range giving a quicker reuse. o MADV_FREE will garbage-collect the pages and swap resources causing the next fault to either page in new pages from backing store (mapped vnode) or allocate new zero-fill pages (anonymous mapping).
2001-05-10Some locking protocol fixes and better enforcement of wiring limits.Artur Grabowski
From NetBSD.
2001-05-09More sync to NetBSD.Artur Grabowski
- Change pmap_change_wiring to pmap_unwire because it's only called that way. - Remove pmap_pageable because it's seldom implemented and when it is, it's either almost useless or incorrect. The same information is already passed to the pmap anyway by pmap_enter and pmap_unwire.
2001-05-06iprintf is not used with UVMArtur 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.
2001-05-05Get rid of CLSIZE and all related stuff.Artur Grabowski
CLSIZE -> 1 CLBYTES -> PAGE_SIZE OLOFSET -> PAGE_MASK etc. At the same time some archs needed some cleaning in vmparam.h so that goes in at the same time.
2001-04-07Always get struct pglist from vm/pglist.h, otherwise old VM compilationsNiklas Hallqvist
generate redefinition errors.
2001-04-06Get rid of vm_pmap from struct vmspace.Artur Grabowski
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.
2001-03-26Add to ifdef confusion.Artur Grabowski
The _pmap_enter kludge only applies to i386.
2001-03-23Take vm_pmap out of struct vmspace if we are using UVM since UVM doesn'tTodd C. Miller
use that. Fixes size mismatch in i386 pmap.new kernel. This requires that users rebuild libkvm and friends using the new headers for ps et al to work with a new kernel.
2001-03-22Merge in NetBSD's PMAP_NEW, still disabledNiklas Hallqvist
2001-03-21Ok, I'm breaking my promise. I promised to not do anything with theArtur Grabowski
old vm system and I hoped that it would make people help me to switch all archs to uvm. But that didn't help. Fix pool to work with the old vm system (not optimal, ha!).
2001-03-09Add mlockall and munlockall (dummy for the old vm system).Artur Grabowski
2001-03-09More syncing to NetBSD.Artur Grabowski
Implements mincore(2), mlockall(2) and munlockall(2). mlockall and munlockall are disabled for the moment. The rest is mostly cosmetic.

2001-03-01Fix compilation problems caused by last updateConstantine Sapuntzakis
2001-02-28Get rid of VHOLD, replace with buf_replacevnode.Constantine Sapuntzakis
2001-02-24Cleanup of vnode interface continues. Get rid of VHOLD/HOLDRELE.Constantine Sapuntzakis
Change VM/UVM to use buf_replacevnode to change the vnode associated with a buffer. Addition v_bioflag for flags written in interrupt handlers (and read at splbio, though not strictly necessary) Add vwaitforio and use it instead of a while loop of v_numoutput. Fix race conditions when manipulation vnode free list

2000-05-27Make this compile for VM_PSTRAT_RANDOM.Artur Grabowski
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.

1999-12-30swap encryption for UVM, option UVM_SWAP_ENCRYPT. needs to be enabledNiels Provos
via sysctl. Pages are encrypted with the Blowfish encryption algorithm, the key is initialized randomly on first swap out, ensuring that entropy has accumulated in the kernel randomness pool. Eventually, swap encryption will be decided on a process by process basis, e.g. a process that reads from a cryptographic filesystem will enable swap encrypt for its pages. okay art@ and deraadt@.

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.
