thorpej 330d142f16 vm_offset_t -> {vaddr_t,paddr_t}, vm_size_t -> vsize_t 1998-08-13 21:36:02 +00:00
thorpej 1bd007d54b Define 2 free lists: a default, and a "first16", which is where the first
16M of RAM goes (in an effort to protect ISA DMA-safe memory).

thorpej 032c433933 Just commit to using MACHINE_NEW_NONCONTIG. 1998-01-15 22:20:15 +00:00
mrg 057795048f this is the i386 MD portion of the MACHINE_NEW_NONCONTIG code, as
written by chuck cranor.  thanks to mycroft for helping me find the
one little line of code i accidentally deleted while merging it.

this is not enabled by default.  `options MACHINE_NEW_NONCONTIG'
will use this code.  eventually, this should go into <machine/vmparam.h>
insteaed of MACHINE_NONCONTIG.

fvdl 74f97b28cc Change various constants that depend on the kernel VM base address. Lower
it to 0xf0000000 to give it more breathing space.

fvdl 3dc301ff58 Include VM_MAX_KERNEL_BUF constant to put a cap on buffer cache KVM usage.
Override via config file possible.

XXX this is a stopgap measure.

mycroft 7131e8517e Garbage collection. 1994-01-03 16:20:47 +00:00
cgd dced52af6c bump MAXSSIZ back down to 8M (from 256M, where charles put it).
execve() currently allocated MAXSSIZ of address space (AND PAGE TABLES)
for the stack.  until that's changed, and the stack-handling code is
updated to match, MAXSSIZ==256M will make execve() significantly slower
than MAXSSIZ==8M.

cgd 59a008c712 change maximum stack size to 8M. 1993-09-04 22:21:28 +00:00
cgd 2403a33987 decouple MAXDSIZ and MAXSSIZ. MAXSSIZ now is 2M; shouldn't need more,
and saves time in exec.

cgd 499f536ddc up default data size limit to 16M, like on freefall, so everything will
