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 253 drivers are converted, the remaining 1/2 need more changes. 254 255 As of import this is snapshot of work in progress and so 256 may not compile; in particular the midi changes are very 257 much "in progress". The audio component has been tested 258 and verified to work with emuxki and auvia. There may 259 be a locking issue in the ac97 code at boot. 260 261 The are two locks per device instance, an ISR lock and 262 a character device lock. The ISR lock replaces calls to 263 splaudio()/splx(), and will be held across calls to device 264 methods which were called at splaudio() before (e.g. 265 trigger_output). The character device lock is held across 266 calls to nearly all of the methods, excluding some only 267 used for initialization, e.g. get_locks. This needs to be 268 documented at merge time. 269 270 To test on a multi way x86 system, search for "mpsafe" in 271 x86/x86/intr.c and change IPL_SCHED to IPL_AUDIO. Run a job 272 that will acquire the ISR lock (depends on the hardware, but 273 "while true; do mixerctl -a > /dev/null; done" may suffice). 274 Play audio, run lockstat and verify that that there is 275 contention on the ISR lock. 276 277Branch: ad-audiomp2 278Description: Add MP locking to the audio drivers 279Status: Terminated 280Start Date: 7 December 2008 281End Date: 19 November 2011 282Base Tag: ad-audiomp2-base 283Maintainer: Andrew Doran <ad@NetBSD.org> 284Scope: kernel 285Notes: Ressurect ad-audiomp, make the audio drivers MP safe. 286 287Branch: agc-netpgp-standalone 288Description: Remove dependency on openssl libraries in netpgp 289Status: Active 290Start Date: 5 May 2012 291End Date: 292Base Tag: agc-netpgp-standalone-base 293Maintainer: Alistair Crooks <agc@NetBSD.org> 294Scope: src/crypto/external/bsd/netpgp 295Notes: This branch is used to develop the version of netpgp 296 which has its own version of bignum, ciphers, and signatures 297 libraries, so that it is able to operate without openssl 298 being in place. 299 300Branch: bjh21-hydra 301Description: Simtec Hydra support and ARM SMP in general 302Status: Dormant 303Start Date: 18 Oct 2002 304End Date: 305Base Tag: bjh21-hydra-base 306Maintainer: Ben Harris <bjh21@NetBSD.org> 307Scope: sys/arch/arm sys/arch/acorn32 308Notes: This code was on a branch because it involves changes to 309 cpuswitch.S which would otherwise make merging the 310 nathanw_sa branch difficult. 311 312Branch: cherry-xenmp 313Description: Port i386 and amd64 Xen kernels to run MP 314Status: Terminated 315Start Date: 1st June 2011 316End Date: 13th January 2012 317Base Tag: cherry-xenmp-base 318Maintainer: Cherry G.

If you plan to 531 continue this branch, sys/netinet/in_pcb.h already contains 532 the proposed structure layout (which was roughly discussed 533 in the tech-net mailing list). 534 I also defined INP_*() macros to mimicate FreeBSD's inpcb 535 locking style, but currently they do nothing and are not 536 yet called at the correct places (needs discussion about 537 kernel fine-grained locking). 538 To continue this branch, one needs to read all the relevant 539 inpcb/in6pcb source files and change the function names, 540 structure names, structure fields according to the new 541 layout (in6pcb is gone). 542 Don't try to build a kernel from this branch because it won't 543 work. The missing pieces required to do a complete build 544 were not committed because they were incomplete and generated 545 panics. 546 You shouldn't need to worry about KAME syncs because 547 they did most of them by now. 548 After the work is done, you are required to test the branch 549 (before the merge to -current) with an interop IPv6 test. 550 More info at: http://www.tahi.org/ 551 552Branch: wrstuden-fixsa 553Description: Fix a number of issues present with Scheduler Activations. 554Status: Active 555Start Date: 15 May 2007 556End Date: 557Base Tag: wrstuden-fixsa-base 558Maintainer: Bill Stouder-Studenmund <wrstuden@NetBSD.org> 559Scope: src, though all the interesting stuff is in the kernel 560 or lib/libpthread or maybe gdb. 561Notes: This branch is based off of the netbsd-4 branch! 562 This branch is intended to stage improvements for the 563 Scheduler Activations system for NetBSD 4. Improvements 564 include not allocating memory while preparing to tsleep(), 565 reducing inappropriate upcall delivery (hopefully also 566 eliminating the need to mlock stacks), and being 567 able to pthread_kill() running threads. At this date, 568 most goals have been achieved. This branch also includes 569 fixes to gdb to support working with threaded apps. 570 571Branch: wrstuden-revivesa 572Description: Fix a number of issues present with Scheduler Activations. 573Status: Active 574Start Date: 10 May 2008 575End Date: 576Base Tag: wrstuden-revivesa-base 577Maintainer: Bill Stouder-Studenmund <wrstuden@NetBSD.org> 578Scope: src, though all the interesting stuff is in the kernel 579Notes: This branch is intended to revive Scheduler Activations 580 in -current in the 5.0 era. This branch's main goal is 581 to re-add syscall compatability so that SA-based libpthread 582 programs can run with a -current kernel. 1:1 threading will 583 remain the NetBSD-default. This branch will re-add necessary 584 upcall support, and will also serve as a chance to clean 585 out cruft that had accumulated in the implementation over 586 time. 587 588Branch: yamt-kmem 589Description: 590 - separate kernel va allocation from kernel fault handling. 591 - make kmem_alloc interrupt-safe. 592Status: Active 593Start Date: Sun Dec 9 2007 594End Date: 595Base Tag: yamt-kmem-base3 596Maintainer: YAMAMOTO Takashi <yamt@NetBSD.org> 597Scope: src/sys (src/common is tagged but not branched) 598Notes: 599 todo: 600 - investigate if PMAP_PREFER equivalent can be done 601 with vmem_xalloc. find a tester with hardware for it. 602 - g/c replaced code, including kmapent and malloc. 603 - consider to remove other submaps. eg. mb_map 604 605Branch: yamt-nfs-mp 606Description: make nfs client mp-safe 607Status: Active 608Start Date: Sun Apr 27 2008 609End Date: 610Base Tag: yamt-nfs-mp-base11 611Maintainer: YAMAMOTO Takashi <yamt@NetBSD.org> 612Scope: src/sys (src/common is tagged but not branched) 613Notes: 614 615Branch: yamt-pagecache 616Description: page cache related changes 617Status: Active 618Start Date: Wed Nov 2 2011 619End Date: 620Base Tag: yamt-pagecache-base3 621Maintainer: YAMAMOTO Takashi <yamt@NetBSD.org> 622Scope: src 623Notes: - maintain object pages in radix tree rather than rb tree. 624 - shrink the size of vm_page. 625 - reduce unnecessary page scan in putpages. esp. when an 626 object has a ton of pages cached but only a few of them 627 are dirty. 628 - reduce the number of pmap operations by tracking page 629 dirtiness more precisely in uvm layer. 630 - fix nfs commit range tracking. 631 - fix nfs write clustering.

In terms of UBC, the primary cache for 1488 file data is the VM cache, which needs to operate 1489 in terms of VM pages. As no existing device has native 1490 pages the same size as our VM pages, there already is 1491 a mapping going on between the VM system and the 1492 underlying blocks. So it would be easier and cleaner 1493 to adjust that to deal w/ different block sizes. 1494 Also with UBC, all i/o is in terms of bytes at an offset 1495 with a certain length, so the exact block size isn't a big 1496 deal. 1497 1498 Any other wrstuden-devbsize tag may (and should) go away. 1499 1500Branch: yamt-idlelwp 1501Description: idle lwp, and some changes depending on it. 1502 1503 1. separate context switching and thread scheduling. 1504 (cf. gmcgarry_ctxsw) 1505 2. implement idle lwp. 1506 3. clean up related MD/MI interfaces. 1507 4. make scheduler(s) modular. 1508 1509Status: Terminated; merged to -current 1510Start Date: Fri Feb 17 2007 1511End Date: Thu May 17 2007 1512Base Tag: yamt-idlelwp-base8 1513Maintainer: YAMAMOTO Takashi <yamt@NetBSD.org> 1514Scope: src/sys (src/common is tagged but not branched) 1515Notes: 1516 Status of ports: 1517 alpha [ Done, UP tested, MP not tested ] 1518 i386 [ Done, tested ] 1519 amd64 [ Done, tested ] 1520 mips [ Done, both MIPS1 and MIPS3 tested] 1521 sparc [ Done, UP tested, MP might have 1522 some problem after newlock2 merge ] 1523 sparc64 [ Done, tested ] 1524 arm [ Done, SA1 tested.
