thorpej beb8d06638 Generally update the comment above vunmapbuf(). 1999-05-26 22:19:33 +00:00
thorpej a2d06a4721 Generally update the comment above the vmapbuf() implementations. 1999-05-26 22:07:36 +00:00
thorpej 2580d306ab Change the vm_map's "entries_pageable" member to a r/o flags member, which
has PAGEABLE and INTRSAFE flags.  PAGEABLE now really means "pageable",
not "allocate vm_map_entry's from non-static pool", so update all map
creations to reflect that.  INTRSAFE maps are maps that are used in
interrupt context (e.g. kmem_map, mb_map), and thus use the static
map entry pool (XXX as does kernel_map, for now).  This will eventually
change now these maps are locked, as well.

thorpej 5b897f96c5 msgbuf doesn't need VM_PROT_EXEC. 1999-05-25 23:31:14 +00:00
thorpej f197609d93 Add some DIAGNOSTIC checks for inconsistent use of pmap_enter/pmap_kremove. 1999-05-25 20:33:33 +00:00
thorpej f311a1c308 Make a slight modification of pmap_growkernel() -- it now returns the
end of the mappable kernel virtual address space.  Previously, it would
get called more often than necessary, because the caller only new what
was requested.

Also, export uvm_maxkaddr so that uvm_pageboot_alloc() can grow the
kernel pmap if necessary, as well.  Note that pmap_growkernel() must
now be able to handle being called before pmap_init().

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 f98d358a1f Rework layer 2 protocol input routines. Instead of calling e.g. ether_input()
directly, call the function pointer (*if_input)(ifp, m).  The input routine
expects the packet header to be at the head of the packet, and will adjust
as necessary.  Privatize the layer 2 input and output routines, allowing
*_ifattach() to set them up as appropriate.

thorpej c10a926030 Allow the caller to specify a stack for the child process. If NULL,
the child inherits the stack pointer from the parent (traditional
behavior).  Like the signal stack, the stack area is secified as
a low address and a size; machine-dependent code accounts for stack
direction.

This is required for clone(2).

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 93768384ee Fix a bug in pmap_collect_pv(), even though nobody currently uses it:
When we put a page on the collection list, we must subtract NPVPPG from the
total free count: one for each pv_entry that's free in that page, and one for
each free pv_entry in other pages that we're going to eat by moving the ones
in the page being collected.

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.

bouyer f20d50fae4 Add byte_swap.h here too. 1999-01-16 02:31:54 +00:00
bouyer dc306354b0 Move the bswap functions from libutil to libc (this bups the
minor of libc and the major of libutil). For little-endian architectures
merge the bnswap() assembly versions with nto* and hton* using symbols
aliasing. Use symbol renaming for the bswap function in this case to avoid
namespace pollution.
Declare bswap* in machine/bswap.h, not machine/endian.h. For little-endian
machines, common code for inline macros go in machine/byte_swap.h
Sync libkern with libc.
Adjust #include in kernel sources for machine/bswap.h.
