fvdl d5aece61d6 Back out the lwp/ktrace changes. They contained a lot of colateral damage,
and need to be examined and discussed more.
2003-06-29 22:28:00 +00:00
darrenr 960df3c8d1 Pass lwp pointers throughtout the kernel, as required, so that the lwpid can
be inserted into ktrace records.  The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.

Bump the kernel rev up to 1.6V

ragge f5cb3ec885 Teach the lkm code to add loaded module symbols to the in-kernel symbol table.
XXX - The way this works is clumsy, at least. It will be fixed as soon as
the in-kernel linker is in place.

jdolecek 075efbb3db desupport LMRESERV_O, anything using it doesn't have chance of working
anyway due to numerous kernel structure changes

thorpej e0d8d366df Merge the nathanw_sa branch. 2003-01-18 10:06:22 +00:00
thorpej 80f8dbe30a Add a new VM map, lkm_map, which machine-dependent code can provide
in the event that it needs to use a special VM range (x86_64 falls
into this category).  We fall back onto kernel_map if machine-dependent
code doesn't create a special map.

jdolecek e0cc03a09b merge kqueue branch into -current
kqueue provides a stateful and efficient event notification framework
currently supported events include socket, file, directory, fifo,
pipe, tty and device changes, and monitoring of processes and signals

kqueue is supported by all writable filesystems in NetBSD tree
(with exception of Coda) and all device drivers supporting poll(2)

based on work done by Jonathan Lemon for FreeBSD
initial NetBSD port done by Luke Mewburn and Jason Thorpe

gehenna a1d78935eb overload block/character into u_long field.
kern/18234: slightly modified
2002-09-13 13:08:53 +00:00
gehenna 77a6b82b27 Merge the gehenna-devsw branch into the trunk.
This merge changes the device switch tables from static array to
dynamically generated by config(8).

- All device switches is defined as a constant structure in device drivers.

- The new grammer ``device-major'' is introduced to ``files''.

	device-major <prefix> char <num> [block <num>] [<rules>]

- All device major numbers must be listed up in port dependent majors.<arch>
  by using this grammer.

- Added the new naming convention.
  The name of the device switch must be <prefix>_[bc]devsw for auto-generation
  of device switch tables.

- The backward compatibility of loading block/character device
  switch by LKM framework is broken. This is necessary to convert
  from block/character device major to device name in runtime and vice versa.

- The restriction to assign device major by LKM is completely removed.
  We don't need to reserve LKM entries for dynamic loading of device switch.

- In compile time, device major numbers list is packed into the kernel and
  the LKM framework will refer it to assign device major number dynamically.

mrg 2f159a1bac remove/move more mach vm header files:
<vm/pglist.h> -> <uvm/uvm_pglist.h>
	<vm/vm_inherit.h> -> <uvm/uvm_inherit.h>
	<vm/vm_kern.h> -> into <uvm/uvm_extern.h>
	<vm/vm_object.h> -> nothing
	<vm/vm_pager.h> -> into <uvm/uvm_pager.h>

also includes a bunch of <vm/vm_page.h> include removals (due to redudancy
with <vm/vm.h>), and a scattering of other similar headers.

mrg 1a8c7604f4 initial import of the new virtual memory system, UVM, into -current.
UVM was written by chuck cranor <chuck@maria.wustl.edu>, with some
minor portions derived from the old Mach code.  i provided some help
getting swap and paging working, and other bug fixes/ideas.  chuck
silvers <chuq@chuq.com> also provided some other fixes.

this is the rest of the MI portion changes.

this will be KNF'd shortly.  :-)

christos 3d1b06ab09 - new copyargs routine.
- use emul_xxx
- deprecate nsysent; use constant SYS_MAXSYSCALL instead.

cgd da93322976 define lkm_nofunc, to be used instead of nosys (blech!) for unused load,
unload, and stat functions.  arguably could (should?) use NULL instead,
but this is a bit more descriptive.  also, unconditionally call the
load/unload/stat functions, as now they're known to work (because, at
worst, they're lkm_nofunc).
