About 1/2 of the drivers are converted, the remaining 1/2 need more changes. As of import this is snapshot of work in progress and so may not compile; in particular the midi changes are very much "in progress". The audio component has been tested and verified to work with emuxki and auvia. There may be a locking issue in the ac97 code at boot. The are two locks per device instance, an ISR lock and a character device lock. The ISR lock replaces calls to splaudio()/splx(), and will be held across calls to device methods which were called at splaudio() before (e.g. trigger_output). The character device lock is held across calls to nearly all of the methods, excluding some only used for initialization, e.g. get_locks. This needs to be documented at merge time. To test on a multi way x86 system, search for "mpsafe" in x86/x86/intr.c and change IPL_SCHED to IPL_AUDIO. Run a job that will acquire the ISR lock (depends on the hardware, but "while true; do mixerctl -a > /dev/null; done" may suffice). Play audio, run lockstat and verify that that there is contention on the ISR lock. Branch: ad-audiomp2 Description: Add MP locking to the audio drivers Status: Terminated Start Date: 7 December 2008 End Date: 19 November 2011 Base Tag: ad-audiomp2-base Maintainer: Andrew Doran Scope: kernel Notes: Ressurect ad-audiomp, make the audio drivers MP safe. Branch: agc-netpgp-standalone Description: Remove dependency on openssl libraries in netpgp Status: Active Start Date: 5 May 2012 End Date: Base Tag: agc-netpgp-standalone-base Maintainer: Alistair Crooks Scope: src/crypto/external/bsd/netpgp Notes: This branch is used to develop the version of netpgp which has its own version of bignum, ciphers, and signatures libraries, so that it is able to operate without openssl being in place. Branch: agc-symver Description: Add library symbol versioning information Status: Active Start Date: 24 March 2013 End Date: Base Tag: agc-symver-base Maintainer: Alistair Crooks Scope: src Notes: This branch is used to develop DSO symbol versioning, allowing symbols to be added, modified and removed from shared libraries. Branch: bjh21-hydra Description: Simtec Hydra support and ARM SMP in general Status: Dormant Start Date: 18 Oct 2002 End Date: Base Tag: bjh21-hydra-base Maintainer: Ben Harris Scope: sys/arch/arm sys/arch/acorn32 Notes: This code was on a branch because it involves changes to cpuswitch.S which would otherwise make merging the nathanw_sa branch difficult. Branch: cherry-xenmp Description: Port i386 and amd64 Xen kernels to run MP Status: Terminated Start Date: 1st June 2011 End Date: 13th January 2012 Base Tag: cherry-xenmp-base Maintainer: Cherry G. Mathew Scope: kernel Notes: None Branch: chris-arm-intr-rework Description: Rework arm interrupt handling code Status: Dormant Start Date: 11 Aug 2007 End Date: Base Tag: chris-arm-intr-rework-base Maintainer: Chris Gilbert Scope: sys/arch/arm sys/arch/cats (other arm archs to follow) Notes: Rework arm interrupt code to provide a shared set of interrupt routines, and allow improvements to be shared across all arm based hardware.

Branch: itohy-usb1 Description: USB stack overhaul, mostly DMA related Status: Terminated Start Date: 22 May 2007 End Date: Base Tag: itohy-usb1-base Maintainer: ITOH Yasufumi Scope: kernel Notes: To check out the kernel source tree, 1. check out checkout script cvs checkout -ritohy-usb1 src/sys/dev/usb/filelist 2. update files in the branch sh -e src/sys/dev/usb/filelist Branch: jruoho-x86intr Description: Cleanup and rework the x86 APIC and PIC subsystems Status: Active Start Date: 17 January 2011 End Date: Base Tag: jruoho-x86intr-base Maintainer: Jukka Ruohonen Scope: kernel Notes: This branch aims to cleanup the x86 interrupt routing code. In particular, a new implementation is provided for all elements of the APIC that involve ACPI. In addition, better abstractions are provided for the whole PIC layer. The main work areas are sys/arch/x86 and sys/dev/acpi. Branch: jym-xensuspend Description: Implement xm save/restore/migrate for NetBSD domU Status: Terminated Start Date: 2009-02-08 End Date: 2011-09-20 Base Tag: jym-xensuspend-base Maintainer: Jean-Yves Migeon Scope: kernel Notes: This branch contains the code required to support the Xen save/restore/migrate facilities.

Branch: mjf-ufs-trans Description: file system transactions for ufs Status: Active Start Date: 12 March 2007 End Date: Base Tag: mjf-ufs-trans-base Maintainer: Matt Fleming Scope: kernel Notes: Branch: nick-net80211-sync Description: sync of net80211 with FreeBSD Status: Dormant Start Date: 21 February 2008 End Date: Base Tag: nick-net80211-base Maintainer: Nick Hudson Scope: sys/ Notes: Sync'ing net80211 with FreeBSD and drivers update. The branch is currently only the kernel, but will likely extend to some userland areas. Branch: pkgviews Description: package views, enabling multiple conflicting packages to co-exist Status: Active Start Date: 22 July 2002 End Date: Base Tag: pkgviews Maintainer: Alistair Crooks Scope: pkgsrc, basesrc/usr.sbin/pkg_install Notes: A more flexible infrastructure for third-party packages by allowing multiple conflicting packages and versions to co-exist within the same tree Branch: rmind-smpnet Description: MP safe network stack (milestone 1): IPv4, UDP and ICMP Status: Active Start Date: 17 July 2013 End Date: Base Tag: rmind-smpnet-base Maintainer: Mindaugas Rasiukevicius Scope: Kernel: src/sys (src/common is tagged but not branched) Notes: Goals: - Improve the abstraction of PCB and other interfaces. - Add PCB and route cache locking, adjust socket locking. - Rework IPv4, UDP and ICMP paths to be MP safe. - Switch UDP sockets to a separate lock, test and benchmark. Branch: rpaulo-netinet-merge-pcb Description: merge in6pcb with inpcb Status: Dormant Start Date: Wed Feb 01 2006 End Date: Base Tag: rpaulo-netinet-merge-pcb-base Maintainer: Rui Paulo Scope: src/sys Notes: No longer active due to the lack of time. If you plan to continue this branch, sys/netinet/in_pcb.h already contains the proposed structure layout (which was roughly discussed in the tech-net mailing list). I also defined INP_*() macros to mimicate FreeBSD's inpcb locking style, but currently they do nothing and are not yet called at the correct places (needs discussion about kernel fine-grained locking). To continue this branch, one needs to read all the relevant inpcb/in6pcb source files and change the function names, structure names, structure fields according to the new layout (in6pcb is gone). Don't try to build a kernel from this branch because it won't work. The missing pieces required to do a complete build were not committed because they were incomplete and generated panics. You shouldn't need to worry about KAME syncs because they did most of them by now. After the work is done, you are required to test the branch (before the merge to -current) with an interop IPv6 test.

Status: Active Start Date: 15 May 2007 End Date: Base Tag: wrstuden-fixsa-base Maintainer: Bill Stouder-Studenmund Scope: src, though all the interesting stuff is in the kernel or lib/libpthread or maybe gdb. Notes: This branch is based off of the netbsd-4 branch! This branch is intended to stage improvements for the Scheduler Activations system for NetBSD 4. Improvements include not allocating memory while preparing to tsleep(), reducing inappropriate upcall delivery (hopefully also eliminating the need to mlock stacks), and being able to pthread_kill() running threads. At this date, most goals have been achieved. This branch also includes fixes to gdb to support working with threaded apps. Branch: wrstuden-revivesa Description: Fix a number of issues present with Scheduler Activations. Status: Active Start Date: 10 May 2008 End Date: Base Tag: wrstuden-revivesa-base Maintainer: Bill Stouder-Studenmund Scope: src, though all the interesting stuff is in the kernel Notes: This branch is intended to revive Scheduler Activations in -current in the 5.0 era. This branch's main goal is to re-add syscall compatability so that SA-based libpthread programs can run with a -current kernel. 1:1 threading will remain the NetBSD-default. This branch will re-add necessary upcall support, and will also serve as a chance to clean out cruft that had accumulated in the implementation over time. Branch: yamt-kmem Description: - separate kernel va allocation from kernel fault handling. - make kmem_alloc interrupt-safe.

XXX hack - fix A->O loaning - write radixtree(9) man page TODO: - benchmark - test - make the write clustering fix less kludgy - fix or disable the ad-hoc per-cpu statistic - disable A->O loan as its benefit is unclear at best tested: i386, amd64, nfs, ffs have good chances to be broken: lfs, sparc64, hp700 the following is kernel build test results. most of NG seem unrelated to the changes in the branch. acorn26 GENERIC OK acorn32 GENERIC OK algor P6032 NG alpha GENERIC OK alpha GENERIC.MP OK amd64 GENERIC OK amd64 XEN3_DOM0 OK amd64 XEN3_DOMU OK amiga GENERIC OK amigappc GENERIC OK arc GENERIC OK atari MILAN-PCIIDE OK bebox GENERIC OK cats GENERIC OK cesfic GENERIC OK cobalt GENERIC OK dreamcast GENERIC NG emips GENERIC OK evbarm NSLU2 NG evbarm TS7200 NG evbmips P6032 NG evbmips MALTA NG evbppc WALNUT NG evbppc EXPLORA451 NG evbppc PMPPC NG evbsh3 COMPUTEXEVB OK ews4800mips GENERIC OK hp300 GENERIC OK hp700 GENERIC OK hpcarm JORNADA720 OK hpcarm JORNADA728 OK hpcmips GENERIC OK hpcsh GENERIC OK hpcsh HPW650PA OK i386 MONOLITHIC OK i386 GENERIC OK i386 XEN3_DOM0 OK i386 XEN3_DOMU OK i386 ALL NG ia64 GENERIC OK ia64 GENERIC.SKI NG ibmnws GENERIC OK iyonix GENERIC NG landisk GENERIC OK luna68k GENERIC OK mac68k GENERIC OK macppc GENERIC OK macppc GENERIC.MP OK mipsco GENERIC OK mmeye GENERIC OK mvme68k GENERIC OK mvmeppc GENERIC OK netwinder GENERIC NG news68k GENERIC OK newsmips GENERIC OK next68k GENERIC OK ofppc GENERIC OK ofppc GENERIC.MP NG pmax GENERIC OK prep GENERIC OK rs6000 GENERIC NG sandpoint GENERIC OK sbmips GENERIC NG sbmips GENERIC.MP NG sgimips GENERIC32_IP3x OK shark GENERIC NG sparc GENERIC OK sparc GENERIC.MP OK sparc64 GENERIC OK sun2 GENERIC OK sun3 GENERIC OK usermode GENERIC NG vax GENERIC OK vax GENERIC.MP OK x68k GENERIC OK zaurus GENERIC NG Branch: reinoud-bufcleanup Description: implement and evaluate struct buf usage cleanup strategies. Ideas currently in mind (preference for b): a) 1. use of bio_ops per buffer. 2. allow chaining/overloading of functions in bio_ops and provide some private context. 3. extend the bio_ops with commonly used functionality like pending action counting, custom context passing, last minute processing of buffer data, buffer cache etc. 4. investigate the use of the kcont() continuation-passing framework for async io completion notification for bufs ... b) 1. all sequencing use of B_CALL replaced by device-threads, if possible generic code around BUFQ 2. possibly use kcont() for async IO finished signaling 3. counter of pending and queued actions requestable by IOCTL interface? 4. implement `last minute buffer fixup' calls and maybe even finished I/O calls as vnode operations ...

Status: Terminated; merged to -current Start Date: 21 Feb 2000 End Date: 01 Oct 2002 Base Tag: sommerfeld_i386mpbase_1 Maintainer: Bill Sommerfeld Scope: sys/arch/i386 Notes: Code committed to the branch has booted to multiuser on at least one system. Not guaranteed to compile against mainline since -current may have changed incompatibly with the last branch update; use "cvs update -D" to roll-back the rest of the tree to match. Please get explicit permission from the maintainer before each commit, or your changes will be backed out. Other tags starting with sommerfeld_ are private to the developer and are guaranteed to be unstable. Only the maintainer should move tags. Note that this branch uses a DIFFERENT scheme for syncing with the mainline. the maintainer uses some private scripts for keeping them in sync; if you make commits to the branch to "resynchronize" things, you'll probably do it wrong; instead, ask the maintainer to resynchronize things. See sys/arch/i386/TODO on the branch for a list of known issues with the branch.

Work around this issue by turning on WAPBL_DEBUG_SERIALIZE in rev 1.1.2.11 of vfs_wapbl.c. - Removing large files (sparse only?) takes a long time. Eg, a file created with dd if=/dev/zero of=foox bs=1 count=1 seek=11261748520550 takes 0:00.00 to remove on my test box without logging and 0:22.25 to remove with logging.

Branch: wrstuden-devbsize Description: Modify buffer cache to deal with different devices having different block sizes. Also DEV_BSIZE would go away. Status: Terminated Start Date: Aug or Sept 1999 End Date: 1 Apr 2000 Base tag: wrstuden-devbsize-base Maintainer: Bill Studenmund Scope: kernel Notes: No longer active due to lack of time, and introduction of UBC. In terms of UBC, the primary cache for file data is the VM cache, which needs to operate in terms of VM pages. As no existing device has native pages the same size as our VM pages, there already is a mapping going on between the VM system and the underlying blocks. So it would be easier and cleaner to adjust that to deal w/ different block sizes. Also with UBC, all i/o is in terms of bytes at an offset with a certain length, so the exact block size isn't a big deal. Any other wrstuden-devbsize tag may (and should) go away.

Status: Terminated; merged to -current Start Date: 27 October 2008 End Date: 30 April 2009 Base Tag: nick-hppapmap-base3 Maintainer: Nick Hudson Scope: sys/ Notes: Port of the OpenBSD pmap including support for PA2.0 CPUs in 32-bit mode. Branch: thorpej-atomic Description: Implementation of an atomic memory operations API modeled after the one in Solaris 10. Status: Terminated; merged to -current Start Date: Apr 11 2007 End Date: Nov 18 2007 Base tag: thorpej-atomic-base Maintainer: Jason Thorpe Scope: src/common src/sys Notes: Base atomic primitives need to be implemented for all of the supported architectures: alpha DONE arm DONE hppa i386 DONE ia64 m68k DONE (except for 68010) mips ns32k powerpc DONE except for membar_*() powerpc64 DONE except for membar_*() sh3 sparc DONE except for membar_*() sparc64 DONE except for membar_*() vax x86_64 DONE Tested: alpha NO arm NO hppa NO i386 NO ia64 NO m68k NO mips NO ns32k NO powerpc NO powerpc64 NO sh3 NO sparc NO sparc64 NO vax NO x86_64 NO TODO: all - Need to replace mb_*() with membar_*(). - Audit MUTEX_CAS() and RWLOCK_CAS() uses to see of membar_enter() is required here. - Talk to ad@ -- figure out of non-atomic mutex / rwlock release is actually safe. arm - Consider using a RAS technique like MIPS uses for _lock_cas() and the mutex stubs. Possibly do more than one atomic op as a RAS. Possibly implement mutex stubs using the technique. m68k - Need to do 68010 support. i386 - Need to change when x86_patch() is called so we can test ncpus. powerpc - Figure out if we need barriers in the atomic ops themselves (hopefully not!) x86_64 - Need to change when x86_patch() is called so we can test ncpus. ######################################################################## # Other: ######################################################################## Branch: magnum Description: ?
