thorpej 3ebbe095e0 Change the pmap_extract() interface to:
boolean_t pmap_extract(pmap_t, vaddr_t, paddr_t *);
This makes it possible for the pmap to map physical address 0.

dbj fdba65aa8c renamed splscc to splserial to match spl(9) man page
changed most of the spl* to use _splraise to match current usage
this fixes an observed bug where zstty_attach was calling splzs causing
interrupts to be turned on prematurely.

itojun 5effafcaa6 kernel configuration for IPv6/IPsec. should be in GENERIC in the future.

itojun 427639cdce - Call ip6intr if INET6 is defined.
- remove "need-flag" for mac68k esp driver, as it is not used in anywhere
  and conflicts with IPsec ESP header.

This should be the only MD change in IPv6 support, except kernel config file.
Very sorry if you have any compilation problem with it (I believe it is okay).
If your favorite arch is not included in here, please add a
call to ip6intr() from softintr handle.

abs b02dbae17e In xxx_mediachange(), if there is no callback to the front-end, just
return 0 instead of EINVAL.  In this case, there will only be one media
type, and the upper-level if_media code will ensure that the user is
setting to that type.
This matches changes Jason made a while back to sys/dev/ic/lance.c

thorpej 0288ffb53a pmap_change_wiring() -> pmap_unwire(). 1999-06-17 19:23:20 +00:00
thorpej f5a527bb4e Remove pmap_pageable(); no pmap implements it, and it is not really useful,
because pmap_enter()/pmap_change_wiring() (soon to be pmap_unwire())
communicate the information in greater detail.
1999-06-17 18:21:21 +00:00
thorpej 602d8e81f7 Don't (ab)use uvm_map_pageable() to allocate PT pages. Instead, do
some internal reference counting on PT pages.  We still allocate them
with the page fault routine (a wire-fault, now), but no longer free
PT pages from pmap_pageable().

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.
1999-05-26 19:16:28 +00:00
thorpej 5832084eaf bus_dmamem_map() maps DMA safe memory, which is usually one or more
managed pages, into KVA space.  Since the pages are managed, we should
use pmap_enter(), not pmap_kenter_pa().

Also, when entering the mappings, enter with an access_type of
VM_PROT_READ | VM_PROT_WRITE.  We do this for a couple of reasons:

	(1) On systems that have H/W mod/ref attributes, the hardware
	    may not be able to track mod/ref done by a bus master.

	(2) On systems that have to do mod/ref emulation, this prevents
	    a mod/ref page fault from potentially happening while in an
	    interrupt context, which can be problematic.

This latter change is fairly important if we ever want to be able to
transfer DMA-safe memory pages to anonymous memory objects; we will need
to know that the pages are modified, or else data could be lost!

Note that while the pages are unowned (i.e. "just DMA-safe memory pages"),
they won't consume any swap resources, as the mappings are wired, and
the pages aren't on the active or inactive queues.

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.
1999-05-18 23:52:51 +00:00
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).

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

each free pv_entry in other pages that we're going to eat by moving the ones
in the page being collected.

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.

write operations appear to lose scsi interrupts and causes timeouts.
