cc2c493bc4 Use PAGE_SIZE rather than NBPG. 2003-04-02 07:35:54 +00:00

78ea2dd367 Use __LDPGSZ (which must be == USRTEXT) as the text address for a.out 
executables, and eliminate the USRTEXT constant, which was only used
by the a.out exec code.

662f877587 MAXSLP is defined to be a machine-independent scheduling parameter, 
so move it into sys/param.h.

cf67ac7122 Per discussion w/ chuck and chuck, restructure the md page stuff 
to use a structure called "vm_page_md", and use __HAVE_VM_PAGE_MD
and __HAVE_PMAP_PHYSSEG.

2b27ac7a99 Add a VM_MDPAGE_MEMBERS macro that defines pmap-specific data for 
each vm_page structure.  Add a VM_MDPAGE_INIT() macro to init this
data when pages are initialized by UVM.  These macros are mandatory,
but ports may #define them to nothing if they are not needed/used.

This deprecates struct pmap_physseg.  As a transitional measure,
allow a port to #define PMAP_PHYSSEG so that it can continue to
use it until its pmap is converted to use VM_MDPAGE_MEMBERS.

Use all this stuff to eliminate a lot of extra work in the Alpha
pmap module (it's smaller and faster now).  Changes to other pmap
modules will follow.

f74dfc7755 We use 8K pages on the Amiga. Make PAGE_SIZE and friends into 
compile-time constants.

b8073b401b Garbage-collect the VM_MBUF_SIZE constant. Instead, use the size 
(nmbclusters * mclbytes), so that the right amount of KVA space is
allocated if those variables are patched.

66d6e30a1b Yet another workaround for pmap bugs. Several reports on the port-amiga 
list claim this helps with some big-machine situations.

7eca9aa5d4 fix long standing "bug" with pmap. Basically logic/misunderstanding 
error commited when it was ported from hp300 (mach?).  All
8M + amigas now gain ~1M of physical ram (4M hack removed).
Some minor cleanup.  HAVEVAC code removed as it is for the hp300.

33e84123f7 sys/arch/amiga tree. This is the machdep part required to get the kernel 
up on an A3000. There are still (very) few changes required outside the
arch/amiga tree, so you can't recompile the kernel yet. Support for
third party SCSI controllers for the A2000 is on its way. The kernel is
fully functional (except for a missing ethernet-driver ...). This
tree is based on my version #390.
