* Merge Makefile:1.12, vmstat.c:1.87 from HEAD to RELENG_6:Robert Watson2005-08-192-23/+79
| | | | | | | | | | | | | | | | | | | | | | | | | | | Teach vmstat -m and vmstat -z to use libmemstat(3). Certain statistics from -z are now a bit different due to changes in the way statistics are now measured. Reproduce with some amount of accuracy the slightly obscure layouts adopted by the two kernel sysctls. In the future, we might want to normalize them. GC dosysctl(), which is now no longer used. Merge vmstat.c:1.88 from HEAD to RELENG_6: Minor syntax tweaks: - Remove some extra blank lines. - Remove comments that don't contribute to understanding. - Remove additional blank lines in output added to maximize compatibility with older vmstat output, but that is actually somewhat gratuitous.

* Fixed a misspelling of 0 as NULL.Bruce Evans2004-03-111-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixed a nearby bug. The "play it safe" code in dosysctl() was unsafe because it overran the buffer by 1 if sysctl() filled all of the buffer. Fixed a nearby style bug in output. Not just 1, but 2 extra newlines were printed at the end by "vmstat -m" and "vmstat -z". Don't print any newlines explicitly. This depends on 2 of the many formatting bugs in the corresponding sysctls. First, the sysctls return an extra newline at the end of the strings. This also messes up output from sysctl(8). Second, the sysctls return an extra newline at the beginning of the strings. This is good for separating the 2 tables output by "vmstat -mz" and for starting the header on a new line in plain sysctl output, but gives a bogus extra newline at the beginning for "vm -[m | z]" and "sysctl -n [kern.malloc | vm.zone]". Fixed some nearby style bugs in the source code: - the same line that misspelled 0 as NULL also spelled NULL as 0. - the size was doubled twice in the realloc loop. - the "play it safe" comment was misleading. Terminating the buffer is bogus because dosysctl() is only meant to work with sysctls that return strings and the terminator is part of a string. However, the kern.malloc sysctl has more than style bugs. It also doesn't return a string. Termination is needed to work around this bug. Notes: svn path=/head/; revision=126842

* Fix a couple of issues in the interrupt code:Dag-Erling Smørgrav2003-12-101-21/+13
| | | | | | | | | | | | | | | | | | - Replace overly-complicated (and buggy) -a logic with a much simpler version: -a causes all interrupts to be displayed, otherwise only those that have occurred are displayed. This removes the need for any MD code. - Instead of just making sure intrcnt is large enough, figure out the exact size it needs to be. We derive nintr from this number, and we don't want to risk printing garbage. Note that on sparc64, we end up printing garbage anyway because the names of non-existent interrupts are left uninitialized by the kernel.

| | | | | | | | | | | | The use of libkvm for post-mortem analysis is still supported (though it could use more testing). We can now remove vmstat's setgid bit. While I'm here, hack the interrupt listing code to not display interrupts that haven't occurred unless the -a option was given on the command line, and document this change.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Kernel: Change statistics to use the *uptime() timescale (ie: relative to boottime) rather than the UTC aligned timescale. This makes the device statistics code oblivious to clock steps. Change timestamps to bintime format, they are cheaper. Remove the "busy_count", and replace it with two counter fields: "start_count" and "end_count", which are updated in the down and up paths respectively. This removes the locking constraint on devstat. Add a timestamp argument to devstat_start_transaction(), this will normally be a timestamp set by the *_bio() function in bp->bio_t0. Use this field to calculate duration of I/O operations. Add two timestamp arguments to devstat_end_transaction(), one is the current time, a NULL pointer means "take timestamp yourself", the other is the timestamp of when this transaction started (see above). Change calculation of busy_time to operate on "the salami principle": Only when we are idle, which we can determine by the start+end counts being identical, do we update the "busy_from" field in the down path. In the up path we accumulate the timeslice in busy_time and update busy_from. Change the byte_* and num_* fields into two arrays: bytes[] and operations[]. Userland: Change the misleading "busy_time" name to be called "snap_time" and make the time long double since that is what most users need anyway, fill it using clock_gettime(CLOCK_MONOTONIC) to put it on the same timescale as the kernel fields. Change devstat_compute_etime() to operate on struct bintime. Remove the version 2 legacy interface: the change to bintime makes compatibility far too expensive.
