Zev Weiss a1a027b9bd Axe automated header generation. 
Reasoning:
 - implementation was unsound -- broke down when I added a fairly
   basic macro definition expanding to a struct initializer in a *.c
   file.

 - made it way too easy (e.g. via otherwise totally innocuous git
   commands) to end up with timestamps such that it always ran
   MakeHeader.py but never used its output, leading to overbuild noise
   when running what should be a null 'make'.

 - but mostly: it's just an awkward way of dealing with C code.

Ross Williams 613556faeb Support for ZFS Compressed ARC statistics 2019-09-03 18:44:19 +00:00
Ross Williams e450b58636 Refactor openzfs_sysctl_init() and ZfsArcMeter... 
openzfs_sysctl_init() now returns void instead of int.
The ZfsArcStats->enabled flag is set inside the init function
now, instead of having to be set from its return value.
Preparation for more flag setting in Compressed ARC commit.

ZfsArcMeter_readStats() added and all Meter->values[] setting
moved to it, eliminating duplicated code in

Ross Williams a93edde1a2 Support ZFS ARC stats on FreeBSD 
New meter displays same ARC stats as FreeBSD top(1).
Can be extended to other platforms that support ZFS.

Pulling kstat.zfs.misc.arcstats.c_max as the meter
total, so the meter has a meaningful value to work
up to.

The Text meter displays, first, the maximum
ARC size (Meter.total), then second, the total
ARC used, using the difference between Meter.maxItems
and Meter.curItems to "hide" the used value from the
Bar and Graph drawing functions by using an index
in Meter.values[] that is beyond curItems - 1, but
less than maxItems - 1.

Tobias Kortkamp ecfd6f685e
Fix memory statistics display on FreeBSD/powerpc 
Use the appropriate types when calling sysctl().

Currently, `unsigned long long int` is used for all sizes and on
FreeBSD/powerpc this causes all sysctl() calls in scanMemoryInfo()
to fail as they are actually of different sizes on powerpc, where
(sizeof(unsigned long long int), sizeof(u_long)) == (8, 4)
vs (8, 8) on amd64.  This results in bogus memory sizes being
reported by htop.

Explorer09 6dae8108f8 Introduce CLAMP macro. Unify all MIN(MAX(a,b),c) uses. 
With the CLAMP macro replacing the combination of MIN and MAX, we will
have at least two advantages:
1. It's more obvious semantically.
2. There are no more mixes of confusing uses like MIN(MAX(a,b),c) and
   MAX(MIN(a,b),c) and MIN(a,MAX(b,c)) appearing everywhere. We unify
   the 'clamping' with a single macro.
Note that the behavior of this CLAMP macro is different from
the combination `MAX(low,MIN(x,high))`.
* This CLAMP macro expands to two comparisons instead of three from
  MAX and MIN combination. In theory, this makes the code slightly
  smaller, in case that (low) or (high) or both are computed at
  runtime, so that compilers cannot optimize them. (The third
  comparison will matter if (low)>(high); see below.)
* CLAMP has a side effect, that if (low)>(high) it will produce weird
  results. Unlike MIN & MAX which will force either (low) or (high) to
  win. No assertion of ((low)<=(high)) is done in this macro, for now.

This CLAMP macro is implemented like described in glib
<http://developer.gnome.org/glib/stable/glib-Standard-Macros.html>
and does not handle weird uses like CLAMP(a++, low++, high--) .
