Arnavion 81b64691a7 Move sysfs-reading code to LinuxProcessList.c and add average frequency.
This way the frequency is read from sysfs only once per update cycle
instead of every time the UI is redrawn.

This also changes the code to read from /proc/cpuinfo instead. This is because
reading from scaling_cur_freq stalls for 10ms if the previous read for the file
was more than one second ago. [1] Since htop's update cycle is
longer than that, it would cause the read of each CPU's scaling_cur_freq file
to block the UI for 20ms. This easily led to a noticeable half-second lag on
a 20+ CPU machine.

/proc/cpuinfo also has a 10ms delay, but this applies for the whole file
so the delay does not scale with the number of CPUs. [2]

Arnavion 9703a25d1b Divide by 1000, not 1024, and show more decimals. 2019-08-09 23:22:05 -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.

Shawn Landden bd1d719a61 Linux: add process->starttime and use it for STARTTIME column (#700)
this way a remount of /proc will not reset starttimes
and we can also see startup times for processes started before the mount
of /proc

also record btime (boot time in seconds since epoch) as Linux semi-global

Explorer09 103f1a497a Disable 'make dist' when pkg.m4 is unused in configure
This would prevent a careless future package maintainer from creating a
release tarball with a defective configure script. :)

Also, add a warning in the autogen.sh phase if pkg.m4 is unused.

Require pkg-config as an optional build dependency on Linux (#775)
With this commit:

* if pkgconfig is installed, it will expand the code inside the shell if, adding the pkgconfig-based tests for the dependencies of Linux delay accounting.
* if pkgconfig is not installed, it will add an error message inside the test of Linux delay accounting, telling the user to install pkgconfig and rebuild the configure script if they want to use Linux delay accounting.

The end result is:

* people running Linux
  * will not need pkgconfig when not using delay accounting
  * will need pkgconfig when using delay accounting
    * if they don't have it
      * they are told by configure they need to install it and re-run autogen.sh when running from Git
      * they are told by configure they need to install it and re-run configure when running from the tarball
* people not running Linux
  * will never need pkgconfig

...and in none of the above scenarios the generated configure script produces unexpanded macros for users checking out the sources from Git.

volkov-am 7cfaa9dede MakeHeader.py: Fix for non-utf8 environments (#770)
Header creation fails with non-utf8 locale and python3.
Simply set LC_ALL="C" and use python3 to reproduce the issue.

Squashed the following commits:

* Solaris: Get LWP enumeration working
* Solaris: Make showing and hiding of kernel threads behave
* Solaris: remove usage of lwpstatus that is no longer needed
* Solaris: no discrete access to parent proc structure needed
* Solaris: Restore runtime MaxPid detection after LWP changes
* Solaris: Workaround virtual PID signal issue by shadowing kill() with a macro
* Solaris: Fix unintention double-shifting of virtual PID for LWP enumeration
* Solaris: Add LWPID to default display since LWP enumeration is also default
* Solaris: use PAGE_SIZE_KB from Process.h instead of custom definition
* Solaris: stop LWP enumeration at 1023 LWPs per proc since that is all we can handle in the virtual PID
