simonb da251cb08f Delete a couple of <uvm/uvm_extern.h> includes that were for 
<sys/sysctl.h> only.
 2000-07-22 16:11:02 +00:00
mrg 32aa199ccf remove include of <vm/vm.h> 2000-06-27 17:41:07 +00:00
simonb 38cc1b3975 Add new sysctl node "KERN_SYSVIPC_INFO" with "KERN_SYSVIPC_MSG_INFO", 
"KERN_SYSVIPC_SEM_INFO" and "KERN_SYSVIPC_SHM_INFO" to return the
info and data structures for the relevent SysV IPC types.  The return
structures use fixed-size types and should be compat32 safe.  All
user-visible changes are protected with
	#if !defined(_POSIX_C_SOURCE) && !defined(_XOPEN_SOURCE)

Make all variable declarations extern in msg.h, sem.h and shm.h and
add relevent variable declarations to sysv_*.c and remove unneeded
header files from those .c files.

Make compat14 SysV IPC conversion functions and sysctl_file() static.

Change the data pointer to "void *" in sysctl_clockrate(),
sysctl_ntptime(), sysctl_file() and sysctl_doeproc().

simonb dd06794f0b Remove shmsegs declaration from conf/param.c - it doesn't belong here. 
Instead, put it in kern/sysv_shm.c.

kleink 230876cf26 Merge parts of chs-ubc2 into the trunk: 
* Remove the casts to vaddr_t from the round_page() and trunc_page() macros to
  make them type-generic, which is necessary i.e. to operate on file offsets
  without truncating them.
* In due course, cast pointer arguments to these macros to an appropriate
  integral type (paddr_t, vaddr_t).

Originally done by Chuck Silvers, updated by myself.

ragge 184f8b2c39 First round of discarding the CL* macros. 1999-12-03 21:43:19 +00:00
thorpej dc8ecaa15b Overhaul of the SVID IPC facilities, primarily to use the types specified 
by the Single UNIX Specification version 2, rather than the SVR2-derived
types.  While I was here, I did a namespace sweep to expose the constants
and strucutures, and structure members described by SUSv2; documentation
updates coming shortly.

Fixes kern/8158.

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

tron bac6bb6bf2 No need to get definition of "SYSV..." from "opt_sysv.h" because they 
must be set if these files are compiled.

perry 275d1554aa Abolition of bcopy, ovbcopy, bcmp, and bzero, phase one. 
bcopy(x, y, z) ->  memcpy(y, x, z)
ovbcopy(x, y, z) -> memmove(y, x, z)
   bcmp(x, y, z) ->  memcmp(x, y, z)
  bzero(x, y)    ->  memset(x, 0, y)

thorpej bf51a1d137 uvm_deallocate() takes an address and a size, not an address range. From 
ITOH Yasufumi <yasufu-i@is.aist-nara.ac.jp>, PR #5834.

mrg d90485202c - add defopt's for UVM, UVMHIST and PMAP_NEW. 
- remove unnecessary UVMHIST_DECL's.

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.  :-)

thorpej 36780f9243 Make shmexit() and shmfork() take struct vmspace *'s, not struct proc *'s, 
and update internal interfaces appropriately.

drochner 593f9e43c2 Fix error handling - call wakeup() in error case too. 1997-10-09 08:35:13 +00:00
drochner fa79dfb77e Use a swap pager backed VM object for sysV shm instead of kernel VM. 
Mostly from FreeBSD.

christos da17295d91 Calling shmdt(2) before calling shmat(2) would crash the system because 
p->p_vmspace->vm_shm would be NULL. Protected the rest of the cases where
that might happen too. This was the reason why sunxdoom would panic the
system in SVR4 emulation.

cgd 3748c1aef7 try to insure that the 'default' address for shm segments is the same 
from process to process.  It apparently is on SysV systems, and some
programs depend on this.  Suggested by  John Birrell <jb@werple.mira.net.au>.
 1995-06-29 11:43:17 +00:00
christos 1a5a3c9199 Extracted all of the compat_xxx routines, and created a library [libcompat] 
for them. There are a few #ifdef COMPAT_XX remaining, but they are not easy
or worth eliminating (yet).

pk 1e52ad70a9 We need some compat_10 routines if COMPAT_SUNOS is on (PR #1008). 1995-06-05 12:56:54 +00:00
christos fb371ccef0 tty_tb.c: need to include ioctl_compat.h in order to compile. 
sysv_shm.c: make shm_find_segment_by_shmid global so it can be used by
	    COMPAT_HPUX. There should be a better way...
rest: Add #ifdef COMPAT_HPUX where needed

deraadt 3938d6ba02 initialize shmmax to `# of pages' at compile time; multiply by NBPG at 
boot time (in shminit). This supports architecture families with varying
values for NBPG, and does not break ipcs.
