Introduction

This report covers &os; related projects between October and December 2009. This is the last of the four reports covering 2009, which has shown to be a very important year for the &os; Project. Besides other notable things, a new major version of &os;, 8.0-RELEASE, has been released, while the release process for 7.3-RELEASE is soon to begin.

Thanks to all the reporters for the excellent work! We hope you enjoy reading. Let us also take this opportunity to wish you all a happy and successful new year for 2010.

Please note that the deadline for submissions covering the period between January and March 2010 is April 15th, 2010.

A DAHDI support module for &os; has been created in the official Asterisk SVN repository.

The following drivers are currently ported:

The following HW drivers are currently ported and tested:

The port for dahdi_dynamic_eth and dahdi_dynamic_ethmf is underway. More HW drivers need to be ported. Please let me know if you can provide remote access with serial console to any box with ISDN/T1/E1 HW not currently supported by DAHDI for &os; but supported by DAHDI for Linux. I am also interested in porting drivers for FXO/FXS cards. Please let me know if you can provide a remote access or donate a card. CAM-based ATA implementation Alexander Motin mav@FreeBSD.org Scott Long scottl@FreeBSD.org

Existing ata(4) infrastructure, which has been around many years, has various problems and limitations when compared to modern controllers/device support. Although the CAM subsystem (used for SCSI) is almost as old as ata(4), it is more eligible to solve the current problems. To reduce code duplication and better support border cases such as ATAPI and SAS, we have started to develop a new CAM based ATA implementation.

As such, CAM infrastructure has been extended to support different transports. New transport has been implemented to support PATA/SATA buses. To support ATA disks, a new CAM driver (ada) has been written. ATAPI devices are supported by existing SCSI drivers cd, da, sa, etc. To support SATA port-multipliers another new CAM driver (pmp) has been written. To support most featured and widespread SATA controllers, new drivers ahci(4) and siis(4) have been developed.

To support legacy ATA controllers, a kernel option ATA_CAM has been added. When used, it makes all ata(4) controllers directly available to CAM, deprecating ata(4) peripheral drivers and external APIs. To make this possible, ata(4) code has been heavily refactored, making controller driver API stricter.

Command queuing support gives new ATA implementation up to double performance benefit on some workloads, with 20-30% improvement quite usual.

SATA Port Multiplier support makes it easy to build fast and cheap storage with huge capacities, by using dozens of SATA drives in one system or external enclosures,

Some of that code has been presented in the recently released &os; 8.0-RELEASE but 8-STABLE now includes a much improved version.

Improve timeout and transport error recovery. Improve hot-plug support. Find and fix any show stoppers for legacy ata(4) deprecation. Write a new, more featured driver for Marvell SATA controllers (specifications desired). Write SAS-specific transport and drivers for SAS HBAs (specifications desired). SAS controllers can support SATA devices and multipliers, so it should fit nicely into the new infrastructure. Chromium web browser Ben Laurie ben@links.org test builds and port progress first build information

Chromium is a Webkit-based web browser that is largely BSD licensed. It has been ported from Linux to &os; in October and we have been posting patches and test builds periodically since then. Chromium works well on &os; — it is very fast and stable but there are a handful of rough edges that need to be polished up. Two remaining bugs should probably be fixed before releasing a chromium-devel port. We are looking for volunteers to test and maintain this port to make this BSD browser a viable option on &os; desktop systems.

Fix sporadic rendering freezes. Fix JavaScript interpreter, v8, on i386 architecture. SUJ — Journaled SoftUpdates Jeff Roberson jeff@FreeBSD.org

I have been adding a small intent log to SoftUpdates to eliminate the requirement for fsck after an unclean shutdown. This work has been funded by Yahoo!, iXsystems, and Juniper. Kirk McKusick has been aiding me with design critiques and helping me better understand SoftUpdates.

Extensive testing by myself and Peter Holm has yielded a stable patch. Current users are encouraged to follow the instructions posted to the current@FreeBSD.org mailing list to verify stability in your own workloads. Updates are forthcoming and it is expected to be merged to 9.0-CURRENT before the end of January. Ports to older versions of &os; will be available in SVN under alternate branches. Official backports will be decided by re@ when 9.0-CURRENT is stable.

The changes are fully backwards and forwards compatible as there are very few metadata changes to the filesystem. The journal may be enabled or disabled on existing FFS filesystems using tunefs(8). The log consumes 64 MB of space at maximum and fsck time is bounded by the size of the log rather than the size of the filesystem. Other details are available in my technical journal.

 Ports Collection Mark Linimon linimon@FreeBSD.org The &os; Ports Collection Contributing to the &os; Ports Collection &os; ports monitoring system The &os; Ports Management Team marcuscom Tinderbox

Most of the recent activity has been dealing with the 8.0-RELEASE process. As an experiment, we have tried to decouple the ports QA timeline as much as possible from the src QA timeline. Although this meant that the impact on people actively maintaining and using ports has been much less than in previous releases, it still has not solved the problem of the release going out with a stale set of packages. We are still trying to come up with a better solution for the problem.

The ports count is over 21,000. The PR count jumped to over 1,000 but is now back to around 950.

We are currently building packages for amd64-6, amd64-7, amd64-8, i386-6, i386-7, i386-8, i386-9, ia64-8, sparc64-7, and sparc64-8. This represents the addition of i386-9 and ia64-8 since the last report.

There has been some discussion of when to drop regular package builds for 6.X but no decision has been made yet. The cluster and the port managers are struggling to keep up with so many branches being active all at the same time.

Mark Linimon continues to make progress on the cluster nodes. Almost every node that does not have a hard disk failure is now online. In addition, he continues to make progress debugging problems that occasionally take nodes offline.

The next task is to characterize the overall performance of the build cluster. The question has been asked of us, "what would it take to speed up package builds?" There is no one simple answer. It is not merely a matter of having a larger number of package building machines, so before asking for funding we first need to identify the current bottlenecks. While we are starting to understand the problems on the nodes, the problems on the dispatch machine itself are much harder. Complicating the matter is that there are several periodic processes (ZFS backup, ZFS expiration, and errorlog compression, among others) that can combine to slow that machine significantly. The simultaneous interaction of all these is proving difficult to quantify.

Between Pav Lucistnik and Martin Wilke, many more experimental ports runs have been completed and committed.

We have added 3 new committers since the last report, and 1 older one has rejoined us.

We are still trying to set up ports tinderboxes that can be made available to committers for pre-testing. Most of the remaining ports PRs are "existing port/PR assigned to committer". Although the maintainer-timeout policy is helping to keep the backlog down, we are going to need to do more to get the ports in the shape they really need to be in. Although we have added many maintainers, we still have more than 4,700 unmaintained ports. (See, for instance, the list on portsmon. The percentage remains steady at just over 22%.) We are always looking for dedicated volunteers to adopt at least a few unmaintained ports. As well, the packages on amd64 and especially sparc64 lag behind i386, and we need more testers for those. &os;/sparc64 Marius Strobl marius@FreeBSD.org

The main thing that has taken place since the last Status Report is that I have gotten to the bottom of the remaining PCI problems with Sun Fire V215/V245 and support for these has been completed and since r202023 now is part of 9.0-CURRENT. With some luck it will also be part of the upcoming 7.3-RELEASE.

Some other news:

 3G USB support Andrew Thompson thompsa@FreeBSD.org

Recently, a bunch of new device IDs have been added for the u3g(4) cellular wireless driver; the list should be comparable now with other operating systems around. A lot of these devices have a feature where the unit first attaches as a disk or CD-ROM that contains the Win/Mac drivers. This state should be detected by the u3g driver and the usb device is sent a command to switch to modem mode. This has been working for quite some time but as it is implemented differently for each vendor I am looking for feedback on any units where the auto switchover is not working (or the init is not recognized at all). Please ensure you are running an up to date kernel, like r201681 or later from 9.0-CURRENT, or 8-STABLE after the future merge of this revision.

 The &os; German Documentation Project Johann Kois jkois@FreeBSD.org Benedict Reuschling bcr@FreeBSD.org Martin Wilke miwi@FreeBSD.org German Documentation Project Homepage

We are happy to announce that Benedict Reuschling is now free from mentorship and can commit to the documentation tree on his own.

Since the last status report, the German Documentation Team has chased updates to various sections of the &os; Handbook, FAQ and the German website. Many handbook pages have been updated to the latest version, including chapters about configuration, disks, kernel configuration, printing, multimedia and virtualization.

We require help from volunteers that are willing to contribute bug fixes or translations. The following documents need active maintainership and are a good training ground for those willing to join the translation team:

Read the translations and report bugs to de-bsd-translators@de.FreeBSD.org. Translate articles or missing sections listed above. The &os; Spanish Documentation Project Gábor Kövesdán gabor@FreeBSD.org Introduction to the Spanish Documentation Project Translators' Mailing List

There is one article translation pending review. Apart from this, neither translations nor maintainance work have been done. We need more volunteers, mostly translators but we are glad to have more reviewers, as well. One can join by simply subscribing to the translators' mailing list where all the work is done.

Update Handbook translation. Update webpage translation. Add more article translations. The &os; Hungarian Documentation Project Gábor Kövesdán gabor@FreeBSD.org Gábor Páli pgj@FreeBSD.org Hungarian Web Page for &os; Hungarian Documentation for &os; The &os; Hungarian Documentation Project's Wiki Page Perforce Depot for the &os; Hungarian Documentation Project

In the last months, no new translation has been added. Lacking human resources, we can only manage to keep the existing documentation and web page translations up to date. If you are interested in helping us, please contact us via the the email addresses noted above.

Translate release notes. Add more article translations. The &os; Forums &os; Forums Admins forum-admins@FreeBSD.org &os; Forums Moderators forum-moderators@FreeBSD.org

Since the last report we have seen a growth of 2,000 users on our forums resulting in approximately 10,000 registered users at this time. The posts count is about to reach 60,000 soon, which are contained in almost 9,000 threads.

The sign-up rate still hovers between 50-100 each week. The total number of visitors (including 'guests') is currently hard to gauge, but is likely to be a substantial multiple of the registered userbase.

New topics and posts are actively 'pushed out' to search engines. This in turn makes the forums show up in search results more and more often, making it a valuable and very accessible source of information for the &os; community.

One of the contributing factors to the forums' success is their 'BSD-style' approach when it comes to administration and moderation. The forums have a strong and unified identity and are very actively moderated, spam-free, and with a core group of very active and helpful members, dispensing many combined decades' worth of knowledge to starting, intermediate and professional users of &os;.

 V4L support in Linux emulator J.R. Oldroyd fbsd@opal.com

V4L video support in the Linux emulator is now available.

This work allows Linux applications using V4L video calls to work with existing &os; video drivers that provide V4L interfaces. It is tested and working with the net/skype port and also with browser-based Flash applications that access webcams. An early version has been committed to 9.0-CURRENT and work is in progress to commit the latest version and then MFC. It is also tested on &os;-8.0/amd64 and &os;-7.2/i386.

Note: to be clear, this does not add V4L support to all webcams. The &os; camera driver must already offer V4L support itself in order for a Linux application to be able to use that camera. The multimedia/pwcbsd port provides the pwc(4) driver that already has V4L support. If your camera is supported by a different driver, you will need to enhance that driver to add V4L support.

 The webcamd deamon Hans Petter Selasky hselasky@FreeBSD.org

The webcamd daemon enables hundreds of different USB based webcam devices to be used under the &os;-8/9 operating system. The webcam daemon is basically an application, which is a port of Video4Linux USB webcam drivers into userspace on &os;. The daemon currently depends on libc, pthreads, libusb and the VIDEO4BSD kernel module.

Add support for the remaining Video4Linux USB devices. Make patches for increased buffer sizes, due to higher latency in userspace. Especially for High Speed USB. Group Limit Increase Brooks Davis brooks@FreeBSD.org

Historically, &os; has limited the number of supplemental groups per process to 15 (NGROUPS_MAX was incorrectly declared to be 16). In &os; 8.0-RELEASE we raised the limit to 1023, which should be sufficient for most users and will be acceptably efficient for incorrectly written applications that statically allocate NGROUPS_MAX + 1 entries.

Because some systems such as Linux 2.6 support a larger group limit, we have further relaxed this restriction in 9.0-CURRENT and made kern.ngroups a tunable value, which supports values between 1023 and INT_MAX - 1. We plan to merge this to 8-STABLE before 8.1-RELEASE.

 Syncing pf(4) with OpenBSD 4.5 Ermal Luçi eri@FreeBSD.org Viewing the changes. The actual repo to build from.

This import is based on OpenBSD 4.5 state of pf(4). It includes many improvements over the code currently present in &os;. The actual new feature present in pf45 repository is support for divert(4), which should allow tools like snort_inline to work with pf(4) too.

Currently, the pf(4) import is considered stable with normal kernel, as well as VIMAGE enabled kernels.

pflow(4)/pflog(4)/pfsync(4) need to be made VIMAGE aware. More regression testing is needed. NFSv4 ACL support Edward Tomasz Napierala trasz@FreeBSD.org

Native NFSv4 ACL support in ZFS and UFS has been committed into 9.0-CURRENT. It is expected to be MFCed in order to make it into &os; 8.1-RELEASE.

Support for NFSv4 ACLs in tar(1). MFC. Ralink wireless RT2700U/2800U/3000U run(4) USB driver Akinori Furukoshi moonlightakkiy@yahoo.ca Announcement on the &os; Forums

The run(4) driver brings support for Ralink RT2700U/2800U/3000U USB wireless devices. For detailed information and list of all the supported devices, please see the above mentioned URL. The source code has been imported to the USB P4 repository on January 10, 2010 (172906).

Solve USB_TIMEOUT problem when sending beacons, and/or confirm which chipsets supports AP mode if all of them do not support it. Read TX stats for AMRR on AP mode, and/or confirm which chipsets supports AP mode if all of them do not support it. Maintain the code. &os;/mips The &os;/mips mailing list mips@FreeBSD.org Warner Losh imp@FreeBSD.org

The base/projects/mips branch has been merged into 9.0-CURRENT. The merge is complete and the sanity tests have passed. The code has booted on both a Ubiquiti RouterStation (big endian) as well as in gxemul (little endian).

The branch lived for one year, minus a day, and accumulated much work:

The development branch had been updated incorrectly several times over the past year, and the damage was too much to repair. We have retired the branch and will do further mips development in 9.0-CURRENT for the time being. If you have a checked out tree, the suggested way to update the projects/mips tree you have is to do a "svn switch svn://svn.FreeBSD.org/base/head" in that tree.

I would like to thank everybody that has contributed time, code or hardware to make &os;/mips better.

As development proceeds, I will keep posting updates. In addition, I hope to have some mini "how-to" wiki pages done for people that want to try it out.

We are still investigating how feasible merging all this work into 8-STABLE will be, as it represents a huge leap forward in code stability and quality. Flattened Device Tree for embedded &os; Rafal Jaworowski raj@semihalf.com Project wiki pages Project P4 branch

The purpose of this project is to provide &os; with support for the Flattened Device Tree (FDT) technology, the mechanism for describing computer hardware resources, which cannot be probed or self enumerated, in a uniform and portable way. The primary consumers of this technology are embedded &os; platforms (ARM, AVR32, MIPS, PowerPC), where a lot of designs are based on similar chips but have different assignment of pins, memory layout, addresses bindings, interrupts routing and other resources.

Current state highlights:

Work on this project has been sponsored by the &os; Foundation.

Complete missing pieces for PowerPC (PCI bridge driver conversion to FDT). Complete ARM support. Merge to SVN. HAST — Highly Available Storage Pawel Jakub Dawidek pjd@FreeBSD.org Announcement

HAST software will provide synchronous replication of any GEOM provider (eg. disk, partition, mirror, etc.) or file from one &os; machine (primary node) to another one (secondary node).

Because data is replicated at the block level neither applications, nor file systems have to be modified to take advantage of this functionality.

The functionality that HAST software will provide is very similar to the functionality provided by the DRBD project for Linux.

The HAST project is sponsored by the &os; Foundation.

Work is progressing well; first milestone was reached in December 2009 and the expected project completion date is January 31, 2010.

Check out &os; mailing lists for patches to test in February and wish me good luck!

And by the way, do not forget to donate to the &os; Foundation, as your donations make projects like this possible.

Thank you!

 Wireless mesh networking Rui Paulo rpaulo@FreeBSD.org

Development of the &os; 802.11s stack continues. The code in &os; HEAD has been updated to comply with draft 4.0. Merge to &os; 8-STABLE will be done soon.

The developer is looking for funding to be able to implement mesh link security algorithms and/or coordinated channel access (performance improvement).

 &os; TDM Framework Rafal Czubak rcz@semihalf.com Michal Hajduk mih@semihalf.com

Important changes regarding &os; TDM Framework since the last status report:

Improve various issues regarding working drivers and demo application. Test Si3050 codec driver operation with PSTN. Fully integrate voiceband infrastructure with Zaptel/DAHDI telephony hardware drivers. POSIX utmpx for &os; Ed Schouten ed@FreeBSD.org Announcement POSIX specification NetBSD's implementation OpenSolaris' implementation

On January 13, I removed the utmp user accounting database and replaced it with a new POSIX utmpx implementation. Unfortunately, the upgrade path is a bit complex, because the utmp interface provided almost no library interface to interact with the database files.

This change may have caused some regressions. Some ports may fail to build, while there could also be bugs in the library functions.

Get a list of broken ports. Fix them to comply to standards. Send patches upstream. BSD-licensed iconv Gábor Kövesdán gabor@FreeBSD.org Sources in the Perforce repository

Good compatibility has been ensured and there are only few pending items that have to be reviewed/enhanced. Recently, an enhancement has been completed, which makes it possible to accomplish better transliteration, just like in the GNU version. An initial testing patch is expected at the beginning of February.

Enhance conversion tables to make use of enhanced transliteration. A performance optimization might be done later. BSD-licensed text processing tools Gábor Kövesdán gabor@FreeBSD.org Perforce repository

As 8.0-RELEASE is out, BSD bc/dc can be now committed to 9.0-CURRENT. We are only waiting for an experimental package building to make sure there are no regressions after this change. BSD grep is complete but it cannot be integrated yet because of some regex library issues. We need first a fast and modern regex library so that we can change to BSD grep. BSD sort has few incomplete features and needs some performance review.

Commit BSD bc/dc. Implement remaining features for sort and optimize performance. NVIDIA amd64 driver John Baldwin jhb@FreeBSD.org Release Announcement

NVIDIA has released the first BETA version of its graphics drivers for &os;/amd64. Note that this driver will work on &os; versions 7.3-RELEASE or 8.0-RELEASE and later. It also works on very recent versions of 7.2-STABLE. More details are provided in the official release announcement.

 &os; Bugbusting Team Gavin Atkinson gavin@FreeBSD.org Mark Linimon linimon@FreeBSD.org Remko Lodder remko@FreeBSD.org Volker Werth vwe@FreeBSD.org GNATS BugBusting Experimental report pages PRs recommended for committer evaluation by the bugbusting team Subscription list for the above report)

Bugmeister Gavin Atkinson has now been granted a src commit bit, and is now starting to work through some of our backlog.

The list of PRs recommended for committer evaluation by the Bugbusting Team continues to receive new additions; however, it has not yet achieved high visibility. (This list contains PRs, mostly with patches, that the Bugbusting Team consider potentially ready to be committed as-is, or are probably trivially resolved in the hands of a committer with knowledge of the particular subsystem.) One of the suggestions at the Cambridge devsummit was to create a way for people to be emailed the weekly summary that is posted to freebsd-bugs@, and this has now been implemented. Please email linimon@FreeBSD.org to ask to be added to the recommended_subscribers.txt file (see above).

We continue to classify PRs as they arrive, adding 'tags' to the subject lines corresponding to the kernel subsystem involved, or man page references for userland PRs. These tags, in turn, produce lists of PRs sorted both by tag and by manpage. At this point most of the PRs that refer to supported versions of &os; have been converted, and we are keeping up as new ones come in. We hope that this is making it easier to browse the PR database.

The overall PR count jumped to over 6,200 during the 8.0-RELEASE release cycle but seems to have stabilized at around 6,100. As in the past, we have a fairly good clearance rate for ports PRs but much less so for other PRs. (Partly this is due to the concept of individual ports having 'maintainers'.)

Try to find ways to get more committers helping us with closing PRs that the team has already analyzed. &os;/ia64 Marcel Moolenaar marcel@FreeBSD.org

Work continues on our ia64 port. Many recent commits to help improve stability have been made to 9.0-CURRENT and MFCed to 8-STABLE.

Due to interest from a very motivated user, package builds have been restarted for ia64-8. This is primarily intended as a QA step to discover and fix bugs on ia64, rather than to create packages for upload.

Based on the above, Mark Linimon documented how to add more architectures to the package cluster scheduler. (This work will also be of use in an upcoming effort to start powerpc package builds.)

There are currently 3 ia64 machines online and building packages. The machines seem stable as long as multiple simultaneous package builds are not attempted, in which case they get machine checks. This is puzzling, since other heavy workloads seem stable on the same machines.

Continue to try to understand why multiple simultaneous package builds bring the machines down. Upgrade the firmware on the two machines at Yahoo! to see if that helps the problem. Configure a fourth machine that has been made available to us. Figure out the problems with the latest GCC port on ia64. We can use some help with reviewing the ia64 platform pages and bringing them up-to-date. bwn(4) — Broadcom Wireless driver Weongyo Jeong weongyo@FreeBSD.org bwn(4) sources in P4

bwn(4) is replacing bwi(4) driver for to the following reasons:

Currently, it is tested on big/little endian machines and 32/64-bit DMA operation with STA mode. A major patch for siba(4) is being reviewed before committing into 9.0-CURRENT.

MESH/IBSS/HOSTAP mode is not supported. LP/N PHYs are not supported. &os; Release Engineering Release Engineering Team re@FreeBSD.org

The Release Engineering Team announced &os; 8.0-RELEASE on November 26th, 2009. With 8.0-RELEASE completed planning has begun for 7.3-RELEASE. The schedule has been set with the release date planned for early March 2010.

The Release Engineering Team would like to thank George Neville-Neil (gnn@) for his service on the team. George continues to work with the &os; Project but has stepped down from the Release Engineering Team to focus on other activities.

 IP Payload Compression Protocol support Bjoern A. Zeeb bz@FreeBSD.org

One of the longer outstanding feature problems with the &os; IP security stack, broken IP Payload Compression Protocol (IPcomp) support, has been fixed.

While working on the fix, various problems had been identified:

Patches for all but the zlib support have been committed to 9.0-RELEASE and merged to all supported stable branches including 6-STABLE. Special thanks to Eugene Grosbein for helping with testing.

Fix ng_deflate so that we can make use of Kip Macy's work on an up-to-date unified zlib version in the kernel, which would also fix the last occasional IPcomp hiccups. The &os; Foundation Status Report Deb Goodkin deb@FreeBSDFoundation.org The &os; Foundation Follow us on Twitter

Despite a difficult economy, we more than doubled our number of donors, we raised $269K towards our goal of $300K, and with an improved economy hope to surpass that this year.

We have funded two new projects. One is the Flattened Device Tree by Rafal Jaworowski. And, the second one is Highly Available Storage by Pawel Jakub Dawidek. We continued supporting the New Console Driver by Ed Schouten and Improvements to the &os; TCP Stack by Lawrence Stewart. We also purchased equipment for several projects.

We have big plans for the new year! We are going to significantly increase our project development and equipment spending. Stay tuned for a project proposal submission announcement soon. We just announced that we are accepting travel grant applications for AsiaBSDCon and will be accepting them soon for BSDCan. And, we are working on infrastructure projects to beef up hardware for package-building, network-testing, etc.

Read more about how we supported the project and community by reading our end-of-year newsletter available at http://www.FreeBSDFoundation.org/press/2009Dec-newsletter.shtml.

 Clang replacing GCC in the base system Ed Schouten ed@FreeBSD.org Roman Divacky rdivacky@FreeBSD.org Brooks Davis brooks@FreeBSD.org Pawel Worach pawel.worach@gmail.com

We are again able to build bootable i386/amd64 kernel. Nathan Whitehorn committed a fix to &os;, which enabled LLVM/clang to work mostly fine on PowerPC. There is some preliminary testing of LLVM/clang on ARM and MIPS being done. We have some ideas about sparc64 support which are currently being investigated. You are welcome to contact us if you want to help.

Since the last report, a lot has happened mostly in the area of C++; clang is currently able to build working groff, gperf and devd, i.e. all of the C++ apps we have in base. Unfortunately, it still cannot build any of the C++ libraries — two of them are missing builtins and libstdc++ is broken for other reasons.

Not much happened in the clangbsd branch as we cannot upgrade the clang/llvm there because we are blocked by a bug that requires using newer assembler than we can ship. This might be solved by either fixing this (short term) or using llvm-mc instead of GNU as for assembling (longer term).

Help with ARM/MIPS/sparc64. More testing of clang on 3rd party apps (ports). Discussion on integrating LLVM/clang into &os;. Intel XScale hwpmc(9) support Rui Paulo rpaulo@FreeBSD.org

Preliminary Hardware Performance Counter support for Intel XScale ARM processors was committed to &os; 9.0-CURRENT in December. This adds another supported architecture to hwpmc(9). The system works for basic performance counter usage but more advanced usage scenarios, namely callchain support, are not yet implemented.
