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.

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.

1999-06-23Improved sysv shared memory. Works with UVM.Artur Grabowski
Original work done in FreeBSD, but this code was ported from NetBSD by Chuck Cranor.

1999-05-22Add new vm_swap code for dynamic swap. From netbsd, munged some by me, andTobias Weingartner
others. syscall commit pending.

1999-02-19Allocate the u-area early in fork1 instead of in vm_fork.Artur Grabowski
Now we can return ENOMEM instead of doing a panic when we run out of memory.

(size_t) and don't return EINVAL if it is < 0 in sys_{read,write}. Remove check for uio_resid < 0 uiomove() now that uio_resid is unsigned and brack remaining panics with #ifdef DIAGNOSTIC. vn_rdwr() must now take a size_t * as its 9th argument so change that and clean up uses of vn_rdwr().

1998-03-30do not count proc0 faults (happens in amiga pmap_init)Niklas Hallqvist
1998-03-26correctly count ru_majflt. the fix pulled in from netbsd pr#1397 ischuck
incorrect. calling vm_pager_get() doesn't count as a "majflt" unless the pager returns VM_PAGER_OK. when walking an object chain we can get VM_PAGER_FAIL (indicating that the requested data does not reside in this object and we must continue to walk the chain) -- we don't want to count this as a majflt. i also added code to count ru_minflt.
