Alexander Schlarb 078c2ddde5 Linux: Use /proc/*/smaps_rollup for improved PSS parsing speed 2019-03-20 17:00:49 +01:00
Alexander Schlarb fc0bf546c3 Linux: Add PSS (proportional set size), Swap and SwapPSS calculation
Original code was written by *Craig M. Brandenburg* for htop 1.0.2
Many performance improvements by GitHub user *linvinus*, ported to htop 2.0.2

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.

wangqr da60309fc9 Don't follow process when selecting non-process-specific options
Disable the follow process logic in Action_pickFromVector(), when

process.

Ricardo Nabinger Sanchez 6194c8dcc6 Honour setting of counting CPUs from 0/1 when presenting meters
In the listing of Available Meters for CPUs, the list of CPUs is always
presented by counting them from one.  However, if the user prefers to
count CPUs from zero, this is sometimes confusing when fine-tuning the
meters.

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.

Antoine Motet 9197adf57e Fix CPU usage on OpenBSD
The current OpenBSD-specific CPU usage code is broken. The `cpu`
parameter of `Platform_setCPUValues` is an integer in the interval
[0, cpuCount], not [0, cpuCount-1]: Actual CPUs are numbered from
1, the “zero” CPU is a “virtual” one which represents the average
of actual CPUs (I guess it’s inherited from Linux’s `/proc/stats`).
This off-by-one error leads to random crashes.

Moreover, the displayed CPU usage is more detailed with system,
user and nice times.

I made the OpenBSD CPU code more similar to the Linux CPU code,
removing a few old bits from OpenBSD’s top(1). I think it will be
easier to understand, maintain and evolve.

I’d love some feedback from experienced OpenBSD people.
