Lomanic 6589c5c274 [cpu][linux] Fix #1037 only count logical cores where 2nd field is a number
Tobias Klauser ee12f66e4d cpu, v3/cpu: use sysconf package instead of exec'ing getconf
Currently, ClocksPerSec is determined by exec'ing getconf in func init,
i.e. on startup of every program importing the package. getconf might
not be present on some systems or is not executable by the current user.
To avoid this hard to control dependency, use the
github.com/tklauser/go-sysconf package which implements sysconf(3)
entirely in Go without cgo. The package is supported on all platforms
currently supported by the cpu and v3/cpu package of gopsutil.
Lomanic 976679ee00 [cpu][linux] Get logical cores in Counts() with non-deprecated kernel API first
Implementing https://github.com/giampaolo/psutil/pull/1727#issuecomment-707624964
and bfae1fc4a3
Lomanic 7700262175 [cpu][linux] Fix #849 implement giampaolo/psutil#1727 in Counts() for physical cores

renamed CLK_TCK variables for consistency across OSs
shirou b0025409e9 [cpu][linux]: add cpuinfo parse check.
Segflow 86c7289ccc Fix: use filename in exec.LookPath instead of full path
exec.LookPath searches for the file in the $PATH, which mean giving it an absolute path is against it's own purposes.
Lomanic 200e5fbeab [cpu][linux] Remove regexp in Counts
Also remove some remaining debug print and unnecessary strings.Split

Sam Kleinman 915d1e930e fix panic in starvation situations
shirou 77b5d0080a Merge pull request #311 from sparrc/cpu-times-panic
fix panic when /proc/stat is empty
Cameron Sparr 0c9a1d33cb
fix panic when /proc/stat is empty
don't really know why this would be the case, but I suppose there are
always edge-cases.

Breno Leitao 286927a039 Improve CPU identification for POWER processors
Currently gopsutils fails to indentify the POWER processors family,
returning an almost empty Info() structure.

This patch improves the POWER identification without changing what is
available for x86.
Andreas Henriksson 9d51bfe3bb Allow clock field in /proc/cpuinfo as cpu MHz fallback value
Needed on ppc64le debian porter boxes atleast.

See #230
K.C. Wong 3dc4e52844 Handle the case when the `cpufreq` sysfs does not exist
* on virtualized host, this may happen.
* but we may have a value from parsing `/proc/cpuinfo`
* in this case, we do not return the error if we fail to extra
  a value from `cpufreq/cpuinfo_max_freq`
K.C. Wong 10a1ae2123 Standardize `Mhz` to mean maximum CPU frequency on Linux platform
* resolve #249
* in `cpu_windows.go`, `Mhz` is the value of `MaxClockSpeed`
* on Linux platform, the `Mhz` value is extracted from `/proc/cpuinfo`
  which reflects the current clock speed; treat this as the fallback
  value instead
* read from `cpufreq/cpuinfo_max_freq` under sysfs to get the
  maximum clock speed for `Mhz`, just like for Windows platform
* also fix the path to `cpu.CoreID` value; the filename is `core_id`
K.C. Wong 123a6c9b0d Addressing frequency unit discrepancies
* for Darwin, it is a minor tweak for readability: the value
  returned is in Hz, so using a variable named 'hz' makes more
  sense than 'mhz'
* for Linux, the unit is in kHz so we need to divide the value
  from `cpuinfo_max_freq` by 10^3 to get MHz (see
  cpu-freq/user-guide.txt of the kernel documentation)

Daniel Theophanes fa7f8ba4e8 cpu: CPUInfo returns one item per physical thread. Fix "Cores" to 1 on Linux.
Fixes #104
Daniel Theophanes 0af895258e common: rename package common to internal/common. Add ENV helper funcs.
Package common wasn't used for public functions. Place it in an
internal directory to prevent other packages from using.

Remove the distributed references to "HOST_PROC" and "HOST_SYS"
consts and combine into a common function. This also helps so that
if a env var is defined with a trailing slash all will continue to
work as expected.

Fixes #100
Daniel Theophanes 69221741e8 cpu: allow override of /sys dir. Fix CPUInfo /proc + cpuinfo combine.
Daniel Theophanes ab2cba55ee Merge branch 'master' of https://github.com/shirou/gopsutil into cpu_arm
Daniel Theophanes 9f2e6a74cc cpu: support ARM CPUs.
ARM CPUs don't include the same fields as  x86 and amd64 CPUs in
the /proc/cpuinfo list. Pull information from the /sys/...
device tree as well as updating when a CPU is done in cpuinfo.

Fixes #88
Jonathan Chauncey 0461c50666 chore(*): Fixes #94
Added the ability to fetch an alternative location for /proc via an
environment variable. If the env var is not set it will return /proc as
the default value.
