1999-11-16Optimize the case of writing to /dev/zero like we do in for /dev/nullArtur Grabowski
1999-11-13from chuq@chuq.com: several fixes to copy{in,out,}str() from charlesTheo de Raadt
and myself: don't panic if maxlen == 0, just return ENAMETOLONG. treat maxlen as unsigned like the manpage indicates. avoid crashing if the userspace address is >= KERNBASE. make sure *done is 0 when no bytes are copied.
1999-11-12Break out the allocation of pv entries and 4m pagetables into functions.Artur Grabowski
This is a preparation to make them non-sleeping.
1999-11-11General cleanup of pmap.Artur Grabowski
- MACHINE_NONCONTIG will no longer work and all code that is not MACHINE_NEW_NONCONTIG is removed. - Kill the pv_table hack which adds complexity to the code and wastes some memory, let the vm "handle" the pv lists through the vm_physmem array, this makes allocation a lot easier. - kill the managed() macro, since it was only used to see if pvhead would end up in a "hole" in pv_table. - pvhead() is now a function that returns NULL if the page is unmanaged. It also takes a page number as an argument instead of the physical address, since in most cases pvhead was called as pvhead(ptoa(pa)) anyway and it did an atop internally.

1999-11-05MACHINE_NEW_NONCONTIG is now default even without uvm.Artur Grabowski
1999-11-05Since we no longer allocate the iommu page tables in pmap_bootstrap, we canArtur Grabowski
remove unavail_{start,end} and simplify the code in pmap_page_upload.

1999-09-03in pmap_enter4m use access_type to set the initial mod/ref flags on the pvArtur Grabowski
1999-09-03use setpgt4m for the initial mappings too, not that it really matters sinceArtur Grabowski
those pages are already uncached when needed, but it makes it more obvious what happens here.
1999-09-03We have to set the pagetable pointers with the atomic swap instruction.Artur Grabowski
From NetBSD. (actually from a paper I read recently, but since NetBSD already did that it was easier to grab the code from them)
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.
