thorpej a180cee23b Pool deals fairly well with physical memory shortage, but it doesn't 
deal with shortages of the VM maps where the backing pages are mapped
(usually kmem_map).  Try to deal with this:

* Group all information about the backend allocator for a pool in a
  separate structure.  The pool references this structure, rather than
  the individual fields.
* Change the pool_init() API accordingly, and adjust all callers.
* Link all pools using the same backend allocator on a list.
* The backend allocator is responsible for waiting for physical memory
  to become available, but will still fail if it cannot callocate KVA
  space for the pages.  If this happens, carefully drain all pools using
  the same backend allocator, so that some KVA space can be freed.
* Change pool_reclaim() to indicate if it actually succeeded in freeing
  some pages, and use that information to make draining easier and more
  efficient.
* Get rid of PR_URGENT.  There was only one use of it, and it could be
  dealt with by the caller.

tsutsui 3c8b0446fe Change type of dumpmag to u_int32_t since it is actually 
a 32bit unsigned magic number.
As per discussion on tech-kern, and fixes port-sparc64/11949.

simonb 9bcc70fa1d Don't cast argument to ffs() to long.

simonb 6f0fb25121 Don't need to declare phys_map - it is declared in <uvm/uvm_extern.h>. 2002-03-04 02:43:22 +00:00
simonb 9a942a34e0 Don't use local extern declarations for the mountroot variable or 
declare local prototypes for nfs_mountroot() or md_root_setconf().

christos e8116a8f5b - Use DEV_ constants, instead of documenting the numbers! 
- Delete cdev_decl(mm); where appropriate, and other hand-crufting [hi powerpc!]
 2002-02-27 01:20:51 +00:00
simonb d9ab16ba2f Purge CLSIZE, CLSIZELOG2 and MCLOFSET. 
Be consistant in the way that MSIZE, MCLSHIFT, MCLBYTES and NMBCLUSTERS
  are defined.
Remove old VM constants from cesfic port.
Bump MSIZE to 256 on mipsco (the only one that wasn't already 256).

gmcgarry 5382848ec7 Recognise md as a valid root device. And since md disks don't get 
device_register()'d, don't go looking on our device list for them.
Ramdisk kernel now boot.

gmcgarry 0b0cdf630f Some assemblers will optimise addresses within .text into pc-relative 
references.  Bogus for our MMU trampoline code which is relocated to
the last physical page before being invoked.  This hack enforces all
addresses wrt the MMU trampoline code not to be pc-relative.

jdolecek 6d265bd894 add options PIPE_SOCKETPAIR to individual kernel configs 
the option is commented out on everything but kernels I was able
to recognize as INSTALL-like or ones for small memory machines
 2002-01-27 13:23:08 +00:00
jdolecek ff8305bbac Switch to MI dev/md_root.c for archs which don't have any special 
memory disk hooks (i.e. everything except atari).
 2002-01-21 21:56:57 +00:00
oster 39b858e3bf Add new RF_* options for RAIDframe bits that are no longer built by default. 
While we're here, enable RAIDframe (and RAID_AUTOCONFIG) by default for
architectures that I'm comfortable can deal with it being on by default.

Also: bump the number of 'raid' devices from 4 to 8, since 4 seems to
be insufficient in practise.

chs 9451559ef4 pmap_page_protect(VM_PROT_NONE) must remove all mappings in the PV list, 
even if they are wired.  we need to be able to remove all mappings to
pages that are being freed due to (eg.) file truncation.
 2002-01-02 00:51:33 +00:00
martin b506d6e135 Add PPPoE to all generic kernels that should be able to use it. 
XXX TODO: do this for INSTALL kernels too, add sysinst support and make the
XXX needed binaries available on the ramdisk root fs.

gmcgarry 9370d5d4ef Update hardware drivers with console attachments to the new console 
attachment interface.
 2001-12-14 08:34:27 +00:00
gmcgarry 8038726863 Update the console attach interface now that bus_space is available. 
Basically means that hardware drivers with console attachments are
now largely machine independent.
 2001-12-14 08:29:24 +00:00
gmcgarry 8883bd8ba3 Make the ite interface look a little more like wscons. This is done 
by allowing the hardware drivers to register keyboard and display
support with the ite framework.  Removes the dependence on the hil
keyboard and should make support for dnkbd easier.

An interim fix until wscons arrives.

gmcgarry bdd225baa1 Add a blurb to the top of all GENERIC files. This serves three purposes: 
- to clarify some terminology
- to clarify the intention of the GENERIC file
- to cross-reference some useful man pages
 2001-12-14 05:34:45 +00:00
chs 2dfd15933e change the reference-counting of PT pages to start from zero instead of 
one, so that we don't mess up the global count of wired pages by having
the page's wire_count be non-zero when we free the page.
pointed out by Michael Hitch.
