The Intel CPU "Platform Id" is a 3-bit integer reported by a given MSR.
Intel microcode updates have an 8-bit field to indicate Platform Id
compatibility - one bit in the mask for each of the possible Platform Id
values. To simplify interpretation, report the Platform Id mask also as
a list.
Intel now releases microcode updates in files named after
<family>-<model>-<stepping>. In some cases a single file may include
microcode for multiple Platform Ids for the same family, model, and
stepping. Our current microcode update tooling (/usr/sbin/cpucontrol)
only processes the first microcode update in the file.
This tool splits combined files into individual files with one microcode
update each, named as
<family>-<model>-<stepping>.<platform_id_mask>.
Adding this to tools/ for experimentation and testing. In the future
we'll want to have cpucontrol or other tooling work directly with the
Intel-provided microcode files.

It was an old TRE that had plenty of bugs and no performance gain over
regex(3). I disabled it by default in r323615, and there was some confusion
about what the knob does- likely due to poor naming on my part- to the tune
of "well, it sounds like it should speed things up" (mentioned by multiple
people).
To compound this, I have no intention of maintaining a second regex
implementation. If someone would like to step up and volunteer to maintain a
lean-and-mean implementation for grep, this is OK, but we have very few
volunteers to maintain even our primary regex implementation.
This driver was for an early and uncommon legacy PCI 10GbE for a single
ASIC, Intel 82597EX. Intel quickly shifted to the long lived ixgbe family.

This driver supports legacy, 32-bit PCI devices, and had an ambiguous
license. Supported devices were already reported to be rare in 2003
(when an earlier version of the driver was removed in r123201).

Import the wrapper script from zstdgrep (written by wiz@netbsd.org)
Modify it to support more than just zstd (adding support for gzip,
lzma, xz and bzip2)
Write a simple manpage dedicated for it.
Only use that new wrapper both for gnu grep and bsd grep
Next step will be removing code related to compression format from bsdgrep

Add checks for unallocated inodes and inodes with unknown mode
types.
Cleanup variable declarations by changing from type `int' to types
like ufs_lbn_t, ufs2_daddr_t, etc.

prtblknos filesystem_device inode ...
add an additional argument format:
prtblknos file
which is more convenient than figuring out the filesystem
and inode number for "file".
When given a list of multiple inodes, rather than exiting
the program on an error with one of them, skip over it and
continue with the next one.

regular files, directories, and symbolic links that require
external storage.
Correct the handling of files with holes and files that have
one or more large blocks and end with a fragment.
Reported by: bde
main.c - opens disk and processes the argument list
of inodes to be printed
prtblknos.c - prints out the list of blocks used by an inode
This change allows the fsdb program to import prtblknos() to use when
printing out the set of blocks used by an inode.
This program was switched to using the libufs library to ease its
integration with fsdb and any other filesystem utility that might
want to use it in the future.
It can be used to validate basic algorithm correctness on a variety of inputs,
by comarison to openssl.
While here, add some sanity to the crypto/Makefile.
The tool may not be perfect, but getting it in tree where collaboration can
happen is a nice first step. The pace of development outside of svn seems
to have slowed down mid-2017.

ConnectX-4/5 devices in mlx5core.
The dump is obtained by reading a predefined register map from the
non-destructive crspace, accessible by the vendor-specific PCIe
capability (VSC). The dump is stored in preallocated kernel memory and
managed by the mlx5tool(8), which communicates with the driver using a
character device node.
The utility allows to store the dump in format
<address> <value>
into a file, to reset the dump content, and to manually initiate the
dump.
A call to mlx5_fwdump() should be added at the places where a dump
must be fetched automatically. The most likely place is right before a
firmware reset request.

We require some --globals due to custom loader extensions in our

interested parties can get up and go with linting our scripts and not get a
bunch of false-positives.
