To avoid name collisions, private tags should 10# have names which begin with the developer's NetBSD login name 11# followed by a - or _ character (e.g., thorpej_scsipi, 12# thorpej-signal) 13# 14# Any branch or version tag not listed here should be assumed to be 15# private to the developer who created it.

About 1/2 of the 327 drivers are converted, the remaining 1/2 need more changes. 328 329 As of import this is snapshot of work in progress and so 330 may not compile; in particular the midi changes are very 331 much "in progress". The audio component has been tested 332 and verified to work with emuxki and auvia. There may 333 be a locking issue in the ac97 code at boot. 334 335 The are two locks per device instance, an ISR lock and 336 a character device lock. The ISR lock replaces calls to 337 splaudio()/splx(), and will be held across calls to device 338 methods which were called at splaudio() before (e.g. 339 trigger_output). The character device lock is held across 340 calls to nearly all of the methods, excluding some only 341 used for initialization, e.g. get_locks. This needs to be 342 documented at merge time. 343 344 To test on a multi way x86 system, search for "mpsafe" in 345 x86/x86/intr.c and change IPL_SCHED to IPL_AUDIO. Run a job 346 that will acquire the ISR lock (depends on the hardware, but 347 "while true; do mixerctl -a > /dev/null; done" may suffice). 348 Play audio, run lockstat and verify that that there is 349 contention on the ISR lock. 350 351Branch: ad-audiomp2 352Description: Add MP locking to the audio drivers 353Status: Terminated 354Start Date: 7 December 2008 355End Date: 19 November 2011 356Base Tag: ad-audiomp2-base 357Maintainer: Andrew Doran <ad@NetBSD.org> 358Scope: kernel 359Notes: Ressurect ad-audiomp, make the audio drivers MP safe. 360 361Branch: agc-netpgp-standalone 362Description: Remove dependency on openssl libraries in netpgp 363Status: Active 364Start Date: 5 May 2012 365End Date: 366Base Tag: agc-netpgp-standalone-base 367Maintainer: Alistair Crooks <agc@NetBSD.org> 368Scope: src/crypto/external/bsd/netpgp 369Notes: This branch is used to develop the version of netpgp 370 which has its own version of bignum, ciphers, and signatures 371 libraries, so that it is able to operate without openssl 372 being in place. 373 374Branch: agc-symver 375Description: Add library symbol versioning information 376Status: Active 377Start Date: 24 March 2013 378End Date: 379Base Tag: agc-symver-base 380Maintainer: Alistair Crooks <agc@NetBSD.org> 381Scope: src 382Notes: This branch is used to develop DSO symbol versioning, allowing 383 symbols to be added, modified and removed from shared libraries. 384 385Branch: bjh21-hydra 386Description: Simtec Hydra support and ARM SMP in general 387Status: Dormant 388Start Date: 18 Oct 2002 389End Date: 390Base Tag: bjh21-hydra-base 391Maintainer: Ben Harris <bjh21@NetBSD.org> 392Scope: sys/arch/arm sys/arch/acorn32 393Notes: This code was on a branch because it involves changes to 394 cpuswitch.S which would otherwise make merging the 395 nathanw_sa branch difficult. 396 397Branch: bouyer-socketcan 398Description: Implement a CAN socket layer compatible with linux SocketCAN 399Status: Active 400Start Date: Sun Jan 15 2017 401End Date: 402Base Tag: bouyer-socketcan-base 403Maintainer: Manuel Bouyer <bouyer@NetBSD.org> 404Scope: src/ 405Notes: Some documentation on SocketCAN is there: 406 https://www.kernel.org/doc/Documentation/networking/can.txt 407 408Branch: cherry-xenmp 409Description: Port i386 and amd64 Xen kernels to run MP 410Status: Terminated 411Start Date: 1st June 2011 412End Date: 13th January 2012 413Base Tag: cherry-xenmp-base 414Maintainer: Cherry G.

If you plan to 651 continue this branch, sys/netinet/in_pcb.h already contains 652 the proposed structure layout (which was roughly discussed 653 in the tech-net mailing list). 654 I also defined INP_*() macros to mimicate FreeBSD's inpcb 655 locking style, but currently they do nothing and are not 656 yet called at the correct places (needs discussion about 657 kernel fine-grained locking). 658 To continue this branch, one needs to read all the relevant 659 inpcb/in6pcb source files and change the function names, 660 structure names, structure fields according to the new 661 layout (in6pcb is gone). 662 Don't try to build a kernel from this branch because it won't 663 work. The missing pieces required to do a complete build 664 were not committed because they were incomplete and generated 665 panics. 666 You shouldn't need to worry about KAME syncs because 667 they did most of them by now. 668 After the work is done, you are required to test the branch 669 (before the merge to -current) with an interop IPv6 test. 670 More info at: http://www.tahi.org/ 671 672Branch: wrstuden-fixsa 673Description: Fix a number of issues present with Scheduler Activations. 674Status: Active 675Start Date: 15 May 2007 676End Date: 677Base Tag: wrstuden-fixsa-base 678Maintainer: Bill Stouder-Studenmund <wrstuden@NetBSD.org> 679Scope: src, though all the interesting stuff is in the kernel 680 or lib/libpthread or maybe gdb. 681Notes: This branch is based off of the netbsd-4 branch! 682 This branch is intended to stage improvements for the 683 Scheduler Activations system for NetBSD 4. Improvements 684 include not allocating memory while preparing to tsleep(), 685 reducing inappropriate upcall delivery (hopefully also 686 eliminating the need to mlock stacks), and being 687 able to pthread_kill() running threads. At this date, 688 most goals have been achieved. This branch also includes 689 fixes to gdb to support working with threaded apps. 690 691Branch: wrstuden-revivesa 692Description: Fix a number of issues present with Scheduler Activations. 693Status: Active 694Start Date: 10 May 2008 695End Date: 696Base Tag: wrstuden-revivesa-base 697Maintainer: Bill Stouder-Studenmund <wrstuden@NetBSD.org> 698Scope: src, though all the interesting stuff is in the kernel 699Notes: This branch is intended to revive Scheduler Activations 700 in -current in the 5.0 era. This branch's main goal is 701 to re-add syscall compatability so that SA-based libpthread 702 programs can run with a -current kernel. 1:1 threading will 703 remain the NetBSD-default. This branch will re-add necessary 704 upcall support, and will also serve as a chance to clean 705 out cruft that had accumulated in the implementation over 706 time. 707 708Branch: yamt-kmem 709Description: 710 - separate kernel va allocation from kernel fault handling. 711 - make kmem_alloc interrupt-safe. 712Status: Active 713Start Date: Sun Dec 9 2007 714End Date: 715Base Tag: yamt-kmem-base3 716Maintainer: YAMAMOTO Takashi <yamt@NetBSD.org> 717Scope: src/sys (src/common is tagged but not branched) 718Notes: 719 todo: 720 - investigate if PMAP_PREFER equivalent can be done 721 with vmem_xalloc. find a tester with hardware for it. 722 - g/c replaced code, including kmapent and malloc. 723 - consider to remove other submaps. eg. mb_map 724 725Branch: yamt-nfs-mp 726Description: make nfs client mp-safe 727Status: Active 728Start Date: Sun Apr 27 2008 729End Date: 730Base Tag: yamt-nfs-mp-base11 731Maintainer: YAMAMOTO Takashi <yamt@NetBSD.org> 732Scope: src/sys (src/common is tagged but not branched) 733Notes: 734 735Branch: yamt-pagecache 736Description: page cache related changes 737Status: Active 738Start Date: Wed Nov 2 2011 739End Date: 740Base Tag: yamt-pagecache-base8 741Maintainer: YAMAMOTO Takashi <yamt@NetBSD.org> 742Scope: src 743Notes: - maintain object pages in radix tree rather than rb tree. 744 - shrink the size of vm_page. 745 - reduce unnecessary page scan in putpages. esp. when an 746 object has a ton of pages cached but only a few of them 747 are dirty. 748 - reduce the number of pmap operations by tracking page 749 dirtiness more precisely in uvm layer. 750 - fix nfs commit range tracking. 751 - fix nfs write clustering.

In terms of UBC, the primary cache for 1639 file data is the VM cache, which needs to operate 1640 in terms of VM pages. As no existing device has native 1641 pages the same size as our VM pages, there already is 1642 a mapping going on between the VM system and the 1643 underlying blocks. So it would be easier and cleaner 1644 to adjust that to deal w/ different block sizes. 1645 Also with UBC, all i/o is in terms of bytes at an offset 1646 with a certain length, so the exact block size isn't a big 1647 deal. 1648 1649 Any other wrstuden-devbsize tag may (and should) go away. 1650 1651Branch: yamt-idlelwp 1652Description: idle lwp, and some changes depending on it. 1653 1654 1. separate context switching and thread scheduling. 1655 (cf. gmcgarry_ctxsw) 1656 2. implement idle lwp. 1657 3. clean up related MD/MI interfaces. 1658 4. make scheduler(s) modular. 1659 1660Status: Terminated; merged to -current 1661Start Date: Fri Feb 17 2007 1662End Date: Thu May 17 2007 1663Base Tag: yamt-idlelwp-base8 1664Maintainer: YAMAMOTO Takashi <yamt@NetBSD.org> 1665Scope: src/sys (src/common is tagged but not branched) 1666Notes: 1667 Status of ports: 1668 alpha [ Done, UP tested, MP not tested ] 1669 i386 [ Done, tested ] 1670 amd64 [ Done, tested ] 1671 mips [ Done, both MIPS1 and MIPS3 tested] 1672 sparc [ Done, UP tested, MP might have 1673 some problem after newlock2 merge ] 1674 sparc64 [ Done, tested ] 1675 arm [ Done, SA1 tested.
