Merge pull request #601 from Lomanic/issue551 
Fix #551 Filter out '_Total' results from PerfInfoWithContext and unexport this function.

Also propagate context in perCPUTimes (renamed to perCPUTimesWithContext) and unexport Win32_PerfFormattedData_Counters_ProcessorInformation type.

413cb32b6c Use static initialisation for invoke instances, instead of init funcs 
The order of init function execution is dependant on the order that the
source files are passed to the compiler. This causes issues when
building under other build systems, such as bazel or buck, as they are
not guarenteed to maintain the same file order as the default go tool.

6450c60b61 Eliminate use of sysctl command on FreeBSD 
In order to improve performance and help prevent crashes due to the outstanding fork crash bug:
https://github.com/golang/go/issues/15658

Replace string parsed values from the sysctl command with native reads of sysctl values using unix.SysctlRaw and unix.SysctlUint32.

This also merges OpenBSD and FreeBSD load implementations which are identical.

cpu: Implement Solaris support for Info()
 2017-03-14 01:51:04 +09:00

49ed700c0d cpu: Implement Solaris support for Info() 
This commit adds Solaris(^1) support for the Info() function of package
cpu, with the exception of the L2 cache size which is not trivially
available(^2).

Support is implemented by parsing the output of `isainfo -b -v` (for the
instruction set flags), and `psr-info -p -v` for other information.
Example outputs from a range of different size VMs and Joyent containers
are included as part of the tests.

(^1): This has only been tested with Illumos in the form of SmartOS. I
believe it to be portable to other Illumos distributions but have not
tested on Oracle Solaris.

(^2): Enough support is added here to be usable for my port of
HashiCorp's Nomad to SmartOS.
