lukem e4a87aa1a9 * convert to using MI allocsys(). most ports were using an MD allocsys(), 
although a couple still used the old pre-4.4-lite (?) mechanism.
* use format_bytes() to format the various printf()s that print out memory sizes

thorpej 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.

chs f455dd6596 add a `flags' argument to uvm_pagealloc_strat(). 
define a flag UVM_PGA_USERESERVE to allow non-kernel object
allocations to use pages from the reserve.
use the new flag for allocations in pmap modules.

mycroft 12d512bbb7 Oops; vm_offset_t -> vaddr_t. 1999-03-27 00:30:06 +00:00
mycroft 9c6b797796 Changes for modified pmap_enter() API: 
* Map the message buffer with access_type = VM_PROT_READ|VM_PROT_WRITE `just
  because'.
* Map the file system buffers with access_type = VM_PROT_READ|VM_PROT_WRITE to
  avoid possible problems with pagemove().
* Do not use VM_PROT_EXEC with either of the above.
* Map pages for /dev/mem with access_type = prot.  Also, DO NOT use
  pmap_kenter() for this, as we DO NOT want to lose modification information.
* Map pages in dumpsys() with VM_PROT_READ.
* Map pages in m68k mappedcopyin()/mappedcopyout() and writeback() with
  access_type = prot.
* For now, bus_dma*(), pmap_map(), vmapbuf(), and similar functions still use
  access_type = 0.  This should probably be revisited.

mrg d2397ac5f7 completely remove Mach VM support. all that is left is the all the 
header files as UVM still uses (most of) these.

kleink cb37e264d2 Need <sys/device.h> to bring configure() declaration in scope. 1998-11-24 16:48:26 +00:00
mrg db3051d720 fix problems in many d_mmap routines: 
- returned EOPNOTSUPP rather than -1.
	- no check for negative offset.
many of these fix potential security problems in these drivers.


XXX XXX XXX
the d_mmap cdev routine should be changed to have a prototype like:
	paddr_t (*d_mmap) __P((dev_t, off_t, int));

by someone!

thorpej cabecee13c Changes to support fork_kthread(): 
- cpu_set_kpc() now takes void *arg third argument, passed to the
  entry point.
- cpu_fork() allows parent to be non-curproc iff parent is proc0.
  When forking non-curproc, assume its state has already been saved.
- Adjust various pieces of machine-dependent code to account of all of this.

thorpej 8abe0d6b1c Adjust for the new "reaper" kernel thread: do not free the vmspace and 
u-area in machine-dependent code.  Instead, call exit2() to schedule
the reaper to free them for us, once it is safe to do so (i.e. we are
no longer running on the dead proc's vmspace and stack).

tv 00ede2160e Change ddb_init() for a.out to provision for kernels which are not booted by 
the current 'bootblock' method, like the Shark, which preloads and preformats
the symbol table right in the boot code.

is 7a0f63f982 Back out the defopt for M680?0. As pointed out to me, this breaks ports which 
dont use the M680?0 the way Amiga, Atari, Mac68k, and X68k do. I must have
missed this in the past discussion about this project.

is 6a6812fd92 Move M680[2346]0 to opt_m68kcpu.h. 
XXX Some explicit dependencies could be removed now from the individual

thorpej 6626878e7b It is no longer necessary for pmap_pinit() and pmap_release() to be 
pmap interface functions, as NetBSD no longer uses statically allocated
pmaps (except for the kernel pmap, which is special-cased anyhow).
