martin 00b23860a0 "bufmem" is unsigned long inside the kernel, so don't try to grovel it out
of kmem as a unsigned int.
Also avoid overrunning VCACHE_SIZE, thus scribling over unrelated memory.
Fixes PR port-sparc64/25537.

atatat caea20e952 Add PTRTOUINT64() and UINT64TOPTR() macros to sys/sysctl.h for use by
kern.proc, kern.proc2, kern.lwp, and kern.buf.

Define more MIB for kern.buf so that specific buffers can be selected
(only all/all is supported right now), and use a 32/64 bit agnostic
structure for communcating buffer information to userland.

Convert systat to the new kern.buf method.

Clean up the vm.buf* handling a little.  There's no actual need to
record the dynamically assigned OIDs, since sysctl_data can tell us
what we're looking at.

Oh, and fix a typo in a comment.

pk 498839ae5e Adapt to kernel buffer cache memort allocation changes.
Since the buffer headers do no longer exist as an array in the kernel anymore,
use the new CTL_KERN.KERN_BUF mib to fetch them from kernel space.

Also look at a vnode's specinfo field to properly associate an opened
block device special file with a mounted filesystem.

christos 6a02b7be66 - avoid coredump by returning NULL when read fails and don't keep following
the list.
- avoid zerodivide.
XXX: still does not work, but at least it does not core-dump.

after the window is resized.

simonb 828483a73e Remove extern variables and functions now declared in dkstats.h.
While here, remove 77 (!) unneed #includes.

ad fc3915475d - Add `boot', `run', `time' and `zero' commands to all IP displays. These work
as in the `vmstat' display mode. The default mode is now `time', not `boot'.
- ANSIfy.
- s@kre\(@vmstat\(@.
- __RCSID() police.
- Tweak inet.icmp display visual a little.

jwise 850fb37f89 Fix error handling throughout. First off, it is not true as claimed in swap.c
that `systat doesn't handle errors'.  Second off, errx should not be used directly, since
the terminal should be cleaned up before bailing.  Third off, whatever we do we need
to be consistent.

There, I feel better now.

simonb 7f7397e603 Don't free "buf" in closebufcache() - initbufcache() only gets called
once per systat invocation, not each time we switch to the bufcache
display.

Fixes core dump noted by Andy Doran when switching back and forth to
bufcache display.

mrg 9042b087c4 avoid using CLBYTES (which is based on NBPG). 1999-11-15 10:54:40 +00:00
simonb b80f4eaf1d - Add `bufcache' display which shows buffer cache usage per filesystem,
ala the monitor(1) command for Ultrix.
- Allow `h' or `?' to show the command list (same as `:help').
- Sort commands in cmdtab.c and systat.1
