gperf is used as a build tool for g++ and is not needed for Clang
architectures. Ports and third-party software that need it can use the

includes the function pointer, argument, and whether or not it was run from
hardware interrupt context. The callwheel is marked idle when each handler
completes. This effectively logs the duration of each callout routine in
the graph.

many thanks for their continued support of FreeBSD.
While I'm there, also implement a new build knob, WITHOUT_HYPERV to
disable building and installing of the HyperV utilities when necessary.
The HyperV utilities are only built for i386 and amd64 targets.
This is a stable/10 candidate for inclusion with 10.1-RELEASE.

It is now possible to add options after the encoding in the parameter
list for convert-keymap.pl. This is currently used to selectively
enable interpretation of the ISO8859-1 currency symbol as the Euro
sign found in ISO5589-15, or to add a Yen symbol in place of '\' for
specific Japanese keyboards. The option are appended to the parameter
list, as in e.g. "convert-keymap.pl german.iso.kbd ISO5589-1 EURO".
The options are appended to the encoding in the form "+EURO" or "+YEN"
in KBDFILES.map, to keep the meaning of the columns intact.

1. 50+% of NO_PIE use is fixed by adding -fPIC to INTERNALLIB and other
build-only utility libraries.
2. Another 40% is fixed by generating _pic.a variants of various libraries.
3. Some of the NO_PIE use is a bit absurd as it is disabling PIE (and ASLR)
where it never would work anyhow, such as csu or loader. This suggests
there may be better ways of adding support to the tree. Many of these
cases can be fixed such that -fPIE will work but there is really no
reason to have it in those cases.
4. Some of the uses are working around hacks done to some Makefiles that are
really building libraries but have been using bsd.prog.mk because the code
is cleaner. Had they been using bsd.lib.mk then NO_PIE would not have
been needed.
We likely do want to enable PIE by default (opt-out) for non-tree consumers
(such as ports). For in-tree though we probably want to only enable PIE
(opt-in) for common attack targets such as remote service daemons and setuid
utilities. This is also a great performance compromise since ASLR is expected
to reduce performance. As such it does not make sense to enable it in all
utilities such as ls(1) that have little benefit to having it enabled.

dependent encoding) to NEWCONS (Unicode).
The file "LANG.map" is used to convert INDEX.keymaps. It has 3 columns:
- the language ID as used in the source file
- the language ID to be used in the generated file (e.g. "iw" -> "he")
- the encoding of the menu texts for this language
The conversion result is written to STDOUT.
The file "KBDFILES.map" is used to batch convert keymap files. It's
columns are:
- the encoding used for the keymap sounce file
- the name of the source file
- the name of the generated file
The output files are created in the TEMP sub-directory of the vt keymap
directory, in order to preserve (possibly uncommitted) keymap files in
/usr/src/share/vt/keymaps.
The convert-keymap.pl script can be directly executed by passing the
source file name and the encoding on the command line. It writes to
STDOUT and generates hex Unicode codepoints by default. (This can be
changed to decimal in the script.)
While written for the one-time conversion of the SYSCONS keymaps into
the format required for NEWCONS, I think these tools may be useful for
easy conversion of possible further SYSCONS keymap files, that have not
been committed to the source tree.
Mostly bugfixes or features developed in the past 6 months,
so this is a 10.1 candidate.
Basically no user API changes (some bugfixes in sys/net/netmap_user.h).
In detail:
1. netmap support for virtio-net, including in netmap mode.
Under bhyve and with a netmap backend [2] we reach over 1Mpps
with standard APIs (e.g. libpcap), and 5-8 Mpps in netmap mode.
2. (kernel) add support for multiple memory allocators, so we can
better partition physical and virtual interfaces giving access
to separate users. The most visible effect is one additional
argument to the various kernel functions to compute buffer
addresses. All netmap-supported drivers are affected, but changes
are mechanical and trivial
3. (kernel) simplify the prototype for *txsync() and *rxsync()
driver methods. All netmap drivers affected, changes mostly mechanical.
4. add support for netmap-monitor ports. Think of it as a mirroring
port on a physical switch: a netmap monitor port replicates traffic
present on the main port. Restrictions apply. Drive carefully.
5. if_lem.c: support for various paravirtualization features,
experimental and disabled by default.
Most of these are described in our ANCS'13 paper [1].
Paravirtualized support in netmap mode is new, and beats the
numbers in the paper by a large factor (under qemu-kvm,
we measured gues-host throughput up to 10-12 Mpps).
A lot of refactoring and additional documentation in the files
in sys/dev/netmap, but apart from #2 and #3 above, almost nothing
of this stuff is visible to other kernel parts.
Example programs in tools/tools/netmap have been updated with bugfixes
and to support more of the existing features.
This is meant to go into 10.1 so we plan an MFC before the Aug.22 deadline.
A lot of this code has been contributed by my colleagues at UNIPI,
including Giuseppe Lettieri, Vincenzo Maffione, Stefano Garzarella.
