sys: Remove $FreeBSD$: one-line sh pattern

2023-08-16T17:54:58+00:00

Remove /^\s*#[#!]?\s*\$FreeBSD\$.*$\n/

Make #if and #endif do what people expect in *_if.m

2022-10-06T13:35:31+00:00

These are used in a few places. Pass them to the generated .c and .h
files to allow us to build the parts of the interface the kernel config
supports.

newbus: remove support for SINGLETON

2021-04-26T17:41:08+00:00

Revert rest of de8dd262c43b since it's now unused.

jhibbits@ introduced this to give powerpc MMU functions IFUNC like
performance while retaining the kobj interface, speeding up operations
10-20%. Since there was only ever one instance of the mmu interface
active at any given time, we could cache the looked up results more
agressively.

powerpc migrated to using IFUNCs to get an even larger performance boost
in 45b69dd63e, deleting the two files it was added to in de8dd262c43b.

However, there's few, if any, other potential applications of this to
the tree today. It's now unused and undocumented. Retire it to eliminate
this wart and to preclude the need to document it. Should a simmilar
case arise in the future, the code is in git...

Add a 'SINGLETON' directive to kobj interface definition

2020-01-18T02:39:38+00:00

Summary:
This makes the interface described in the definition file act like a
pseudo-IFUNC service, by caching the found method locally.

Applying this to the PowerPC MMU definitions, it yields a significant
(15-20%) performance improvement, seen in both a 'make buildworld' and a
parallel build of LLVM, on a POWER9 system.

Avoid literal @generated tag in file-generating scripts

2019-05-08T13:35:51+00:00

We don't want the generator itself tagged as a generated file.

Use @generated tag in generated files

2019-05-07T13:04:26+00:00

Multiple tools use @generated to identify generated files (for example,
in a review Phabricator will by default hide diffs in generated files).
Use the @generated tag in makeobjops.awk and vnode_if.awk as we've done
for other generated files.

Teach makeobjops.awk to accept PROLOG and EPILOG blocks before

METHOD and STATICMETHOD declarations; that code will be inserted
into the dispatch function before and after the method call.

Use this functionality and the TSLOG framework to record DEVICE_ATTACH
and DEVICE_PROBE entry/exit timestamps.

sys: further adoption of SPDX licensing ID tags.

2017-11-20T19:43:44+00:00

Mainly focus on files that use BSD 3-Clause license.

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.

Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.

Renumber copyright clause 4

2017-02-28T23:42:47+00:00

Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same
numbering for legal reasons is too pedantic, so give up on that point.

The comment still applies to this block of code.
