Nathan Scott 500fb283e9 Resolve compiler warnings and errors relating to the Arg union
Promote the Arg union to a core data type in Object.c such
that it is visible everywhere (many source files need it),
and correct declarations of several functions that use it.

The Process_sendSignal function is also corrected to have
the expected return type (bool, not void) - an error being
masked by ignoring this not-quite-harmless warning.  I've
also added error checking to the kill(2) call here, which
was previously overlooked / missing (?).

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
{darwin,freebsd,linux,solaris}/Platform.c.

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 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.

Ross Williams 070fe90461 ZFS arcstats for Linux
If no pools are imported (ARC size == 0) or the
ZFS module is not in the kernel (/proc/spl/kstat/zfs/arcstats

Ran Benita 08feb8585b Add pressure stall information (PSI) meters on Linux
The pressure stall information (PSI) metrics provide useful information
on delays caused by waiting for CPU, IO and memory. Particularly on busy
servers it can provide a quick overview of what's "slowing things down".

This feature is supported on Linux >= 4.20.
The interface is documented here:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/plain/Documentation/accounting/psi.txt
These links provide rationale:
https://lwn.net/Articles/759781/
https://facebookmicrosites.github.io/psi/

The following metrics are added, corresponding to the currently exposed
lines (see `head /proc/pressure/*`):
- PressureStallCPUSome
- PressureStallIOSome
- PressureStallIOFull
- PressureStallMemorySome
- PressureStallMemoryFull

The color scheme is the same as that used for Load Average, however I
gave it separate entries just in case someone wants to change them
specifically.

Tested on 4.20.7-arch1-1-ARCH, on the linux platform.
Also tested that other platforms still compile (changed configure to use
the unsupported platform).

Closes #879.
