lib: further adoption of SPDX licensing ID tags. Mainly focus on files that use BSD 2-Clause license, however the tool I was using mis-identified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts.

Remove an obsolete comment in devstat(3) about the accuracy of the milliseconds per transaction (DSM_MS_PER_TRANSACTION) calculation. The comment was accurate many years ago when the kernel didn't record I/O times on a per-I/O basis, but now that we do collect that information in most areas, it isn't correct. The milliseconds per transaction values are correct, assuming the I/O duration has been recorded. Sponsored by: Spectra Logic MFC after: 3 days

Create the altix project branch. The altix project will add support for the SGI Altix 350 to FreeBSD/ia64. The hardware used for porting is a two-module system, consisting of a base compute module and a CPU expansion module. SGI's NUMAFlex architecture can be an excellent platform to test CPU affinity and NUMA-aware features in FreeBSD.

Run a revision of the devstat interface: Kernel: Change statistics to use the *uptime() timescale (ie: relative to boottime) rather than the UTC aligned timescale. This makes the device statistics code oblivious to clock steps. Change timestamps to bintime format, they are cheaper. Remove the "busy_count", and replace it with two counter fields: "start_count" and "end_count", which are updated in the down and up paths respectively. This removes the locking constraint on devstat. Add a timestamp argument to devstat_start_transaction(), this will normally be a timestamp set by the *_bio() function in bp->bio_t0. Use this field to calculate duration of I/O operations. Add two timestamp arguments to devstat_end_transaction(), one is the current time, a NULL pointer means "take timestamp yourself", the other is the timestamp of when this transaction started (see above). Change calculation of busy_time to operate on "the salami principle": Only when we are idle, which we can determine by the start+end counts being identical, do we update the "busy_from" field in the down path. In the up path we accumulate the timeslice in busy_time and update busy_from. Change the byte_* and num_* fields into two arrays: bytes[] and operations[]. Userland: Change the misleading "busy_time" name to be called "snap_time" and make the time long double since that is what most users need anyway, fill it using clock_gettime(CLOCK_MONOTONIC) to put it on the same timescale as the kernel fields. Change devstat_compute_etime() to operate on struct bintime. Remove the version 2 legacy interface: the change to bintime makes compatibility far too expensive. Fix a bug in systat's "vm" page where boot relative busy times would be bogus. Bump __FreeBSD_version to 500107 Review & Collaboration by: ken

Add some features to libdevstat, and overhaul the interface a bit: 1.) prefix all functions in the library with devstat_ (compatability functions are available for all functions that were chaned in an incompatible way, but are deprecated). 2.) Add a pointer to a kvm_t as the first argument to functions that used to get their information via sysctl; they behave the same as before when NULL is passed as this argument, otherwise, the information is obtained via libkvm using the supplied handle. 3.) Add a new function, devstat_compute_statistics(), that is intended to replace the old compute_stats() function. It offers more statistics data, and has a more flexible interface. libdevstat does now require libkvm; a library depedency is added, so that libkvm only needs to be explicitely specified for statically linked programs. The library major version number is bumped. Submitted by: Sergey A. Osokin <osa@freebsd.org.ru>, ken (3) Reviewed by: ken
