Arnavion 1acfb0a752 Show N/A instead of 0KHz when CPU frequency is not available. 2019-08-10 11:37:35 -07:00
Arnavion 4b0600d8f8 Add new display option to also show CPU frequency in CPU meters.
The option is only implemented on Linux. On other platforms, and on Linuxes
that do not expose the relevant sysfs file, the frequency will be 0.

The "CPU average" meter does not show a frequency, only
the individual per-CPU meters.

Hisham Muhammad 8c653212c0 Replace size_t with int/void* union
I was occasionally passing negative values to size_t.
Plus, this better reflects the intent of the variant argument.

Hisham Muhammad 09e241fb12 Security review: check results of snprintf.
Calls marked with xSnprintf shouldn't fail.
Abort program cleanly if any of them does.

Explorer09 1f3d85b617 Mark signal tables 'const'
Specifically, Platform_signals[] and Platform_numberOfSignals. Both are
not supposed to be mutable. Marking them 'const' puts them into rodata
sections in binary. And for Platform_numberOfSignals, this aids
optimization (aids only Link Time Optimization for now). :)

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--) .

Hisham Muhammad 3fe2f3e28e Move list of signals to platform-specific code.
Implementations for Linux (tested) and FreeBSD (still untested, thanks to @etosan for providing the table).
Darwin and OpenBSD(ping @mmcco) builds should be broken now, pending their own tables.

gcc gives warnings like this:

warning: ignoring return value of ‘fscanf’, declared with attribute
warn_unused_result

Hisham Muhammad c2108e5a48 Another mega-patch for the refactoring process.
Kinda runs, but functionality from the original main loop
is still missing. Patience.

Hisham Muhammad 3383d8e556 Sorry about the mega-patch.
This is a work-in-progress, code is currently broken.
(Some actions, and notably, the header, are missing.)
