FreeBSD 11.1 removes cache memory and adds laundry memory. The MIB of
cache memory still exists, but its value is always set to zero.
According to the man page of top(1), the value of laundry memory means
number of dirty pages queued for laundering, suggesting that it should
be added to the 'user' in libgtop because it cannot be freed immediately
without writing out data. Laundry memory was part of inactive memory in
older FreeBSD releases.
FreeBSD systems running on ZFS usually have a large portion of memory
used as ZFS ARC, which has similar purpose to buffer cache of other
filesystems. ZFS ARC can usually be freed quickly when the system needs
more memory, so we don't want to put it in 'user' in libgtop. However,
both buffer cache and ZFS ARC are parts of wired memory, and wired
memory is counted in 'user'. Therefore, we subtract the size of ZFS ARC
from wired memory when calculating 'user' value, making it more useful
to FreeBSD users.
This patch is based on the patch submiited three years ago by
Benoît Dejean <bdejean@gmail.com>.
https://bugzilla.gnome.org/show_bug.cgi?id=748928https://gitlab.gnome.org/GNOME/libgtop/issues/31
Change the value of memory usage from:
Used = Wired
Free = Total - Wired
Shared = 0
Buffer = 0
Cached = Cache
User = Wired - Cache
Locked = Not Supported
To:
Used = Total - Free
Free = Free
Shared = 0
Buffer = Buf
Cached = Cache
User = Active + Wired
Locked = Not Supported
The left-hand side means fields in the glibtop_mem struct and the right-hand
side means the value showed by `top' command. This change should make the value
showed by gnome-system-monitor, which uses `User' field, become closer to
the real memory usage.
All sysctlbyname code in sysdeps/freebsd/mem.c has been moved to separate
functions to make the code cleaner.

* *:
Renamed all glibtop_init_xxx functions
to _glibtop_init_xxx so they get internal visibility.
* configure.in:
Bumped version number.

Closes#407693.

* doc/auto-macros.texi.in: remove unused file.
* doc/libgtop2.texi: don't include auto-macros.texi.
* doc/Makefile.am: don't build auto-macros.texi, since none of its
macros are used in the documentation any more.
* include/glibtop/global.h: don't include <config.h> from headers.
* .../*.c: make sure <config.h> is the first thing included.
* acinclude.m4: m4_include() libgtop-sysdeps.m4 rather than
inlining it.
* acinclude.m4, libgtop-sysdeps.m4: use third argument to
AC_DEFINE() to set the comment.
* configure.in: modernise a bit.
* acconfig.h: remove file, since it is deprecated
* autogen.sh: require automake 1.9 instead of 1.4.
2003-10-19 Carlos Perelló Marín <carlos@gnome.org>
* support/*: Reverted libgtop changes. It's a common module
and I should not modify it.
* Added/removed files. Now the move should be done.

* *.c: kvm_nlist () returns -1 on error, but a positive return value
does not necessarily mean failure. Fixes#3302 which was reported by
Matthias Scheler some time ago.
It changes the return values of all sysdeps functions which were
previosly returning void to int.
This is the first step to implement better error handling in LibGTop.

* include/glibtop/*.h (glibtop_get_*, glibtop_init*): Changed
the return value of all `glibtop_get_<feature>_* ()' and all
`glibtop_init_<feature>_* ()' functions from void to int.
* features.def: Reflect changes of the return values.
* sysdeps/*/*.c: Reflect changes of the return values.
1999-05-26 Martin Baulig <martin@home-of-linux.org>
More NetBSD 1.4 fixes.
* mem.c, procmap.c, procmem.c: Make this work with the new UVM code.
[FIXME: This following most likely works on all BSD systems, but
this needs to be tested; I made it conditional to NetBSD 1.4 at
the moment. Please extend the conditionals to any other systems
where this works ...]
* procstate.c: Added `ruid' and `rgid' for LibGTop >= 1.1.0.
* procuid.c: Added `ngroups' and `groups' for LibGTop >= 1.1.0.

* cpu.c, mem.c, netload.c, procargs.c, procstate.c, proctime.c,
sem_limits.c, shm_limits.c, swap.c: Added initial port for BSD/OS
(aka BSDI) 2.x and 3.x. 4.x should also(?) work.
Still, this port require more close look and extended check.
1999-03-19 Martin Baulig <martin@home-of-linux.org>
Added basic support for BSDI. It compiles without problems on
BSDI 2.1 and 3.1, but it is *untested* - I'm neither root on
the machine nor have I access to /dev/kmem, so I don't know
whether it will work.
You need to give configure the `--enable-hacker-mode' parameter
to use the code.
If someone can verify whether it actually works, please let me
know.

Set the copyright of LibGTop to the GNU General Public License.
* copyright.txt: Set the year to 1998-99 and pretty-format it a
little bit. Same in all C source and header files.
1999-02-22 Martin Baulig <martin@home-of-linux.org>
* COPYING.LIB: Include a copy of the GNU Library General
Public License here.
* copyright.txt: Set the year to 1998-99 and pretty-format it a
little bit. Same in all C source and header files.
1998-12-05 Martin Baulig <martin@home-of-linux.org>
* Make it work with NetBSD 1.3.2.
Well, it compiles without problems but not all features are currently
working; need to look a little bit closer at it.
Ok for now, think I'll install OpenBSD and test it there ...

1998-10-31 Martin Baulig <martin@home-of-linux.org>
* *.c: Use glibtop_warn_io_r () instead of glibtop_error_io_r ().
* proctime.c, prockernel.c, procargs.c: Don't call kvm_uread () if
the /proc filesystem is not mounted.
1998-08-24 Martin Baulig <martin@home-of-linux.org>
* *.c (glibtop_init_p): Using correct `(1 << GLIBTOP_SYSDPES_*)'.
* cpu.c, mem.c: Removed `const' from sysctl () constants to keep
compiler happy.
* procmem.c: Added missing call to `glibtop_init_p'.
* prockernel.c: Casting `nwchan' to `unsigned long' since this
normally has the same size than a pointer. Well, is there a
FreeBSD for 64bit architectures ?
1998-08-06 Martin Baulig <martin@home-of-linux.org>
* include/glibtop/*.h: Using `GLIBTOP_GUILE' instead of `HAVE_GUILE'
so one should be able to use libgtop without guile in an application
even if guile is installed.
* sysdeps/common/mountlist.c: Fixed some `xstrdup' problems.
* lib/open.c: Now correctly reading server features for
`GLIBTOP_METHOD_PIPE'.
* sysdeps/freebsd: New directory.
