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 339 drivers are converted, the remaining 1/2 need more changes. 340 341 As of import this is snapshot of work in progress and so 342 may not compile; in particular the midi changes are very 343 much "in progress". The audio component has been tested 344 and verified to work with emuxki and auvia. There may 345 be a locking issue in the ac97 code at boot. 346 347 The are two locks per device instance, an ISR lock and 348 a character device lock. The ISR lock replaces calls to 349 splaudio()/splx(), and will be held across calls to device 350 methods which were called at splaudio() before (e.g. 351 trigger_output). The character device lock is held across 352 calls to nearly all of the methods, excluding some only 353 used for initialization, e.g. get_locks. This needs to be 354 documented at merge time. 355 356 To test on a multi way x86 system, search for "mpsafe" in 357 x86/x86/intr.c and change IPL_SCHED to IPL_AUDIO. Run a job 358 that will acquire the ISR lock (depends on the hardware, but 359 "while true; do mixerctl -a > /dev/null; done" may suffice). 360 Play audio, run lockstat and verify that that there is 361 contention on the ISR lock. 362 363Branch: ad-audiomp2 364Description: Add MP locking to the audio drivers 365Status: Terminated 366Start Date: 7 December 2008 367End Date: 19 November 2011 368Base Tag: ad-audiomp2-base 369Maintainer: Andrew Doran <ad@NetBSD.org> 370Scope: kernel 371Notes: Ressurect ad-audiomp, make the audio drivers MP safe. 372 373Branch: agc-netpgp-standalone 374Description: Remove dependency on openssl libraries in netpgp 375Status: Active 376Start Date: 5 May 2012 377End Date: 378Base Tag: agc-netpgp-standalone-base 379Maintainer: Alistair Crooks <agc@NetBSD.org> 380Scope: src/crypto/external/bsd/netpgp 381Notes: This branch is used to develop the version of netpgp 382 which has its own version of bignum, ciphers, and signatures 383 libraries, so that it is able to operate without openssl 384 being in place. 385 386Branch: agc-symver 387Description: Add library symbol versioning information 388Status: Active 389Start Date: 24 March 2013 390End Date: 391Base Tag: agc-symver-base 392Maintainer: Alistair Crooks <agc@NetBSD.org> 393Scope: src 394Notes: This branch is used to develop DSO symbol versioning, allowing 395 symbols to be added, modified and removed from shared libraries. 396 397Branch: bjh21-hydra 398Description: Simtec Hydra support and ARM SMP in general 399Status: Dormant 400Start Date: 18 Oct 2002 401End Date: 402Base Tag: bjh21-hydra-base 403Maintainer: Ben Harris <bjh21@NetBSD.org> 404Scope: sys/arch/arm sys/arch/acorn32 405Notes: This code was on a branch because it involves changes to 406 cpuswitch.S which would otherwise make merging the 407 nathanw_sa branch difficult. 408 409Branch: bouyer-socketcan 410Description: Implement a CAN socket layer compatible with linux SocketCAN 411Status: Terminated 412Start Date: Sun Jan 15 2017 413End Date: May 27 2017 414Base Tag: bouyer-socketcan-base 415Maintainer: Manuel Bouyer <bouyer@NetBSD.org> 416Scope: src/ 417Notes: Some documentation on SocketCAN is there: 418 https://www.kernel.org/doc/Documentation/networking/can.txt 419 420Branch: cherry-xenmp 421Description: Port i386 and amd64 Xen kernels to run MP 422Status: Terminated 423Start Date: 1st June 2011 424End Date: 13th January 2012 425Base Tag: cherry-xenmp-base 426Maintainer: Cherry G.

If you plan to 652 continue this branch, sys/netinet/in_pcb.h already contains 653 the proposed structure layout (which was roughly discussed 654 in the tech-net mailing list). 655 I also defined INP_*() macros to mimicate FreeBSD's inpcb 656 locking style, but currently they do nothing and are not 657 yet called at the correct places (needs discussion about 658 kernel fine-grained locking). 659 To continue this branch, one needs to read all the relevant 660 inpcb/in6pcb source files and change the function names, 661 structure names, structure fields according to the new 662 layout (in6pcb is gone). 663 Don't try to build a kernel from this branch because it won't 664 work. The missing pieces required to do a complete build 665 were not committed because they were incomplete and generated 666 panics. 667 You shouldn't need to worry about KAME syncs because 668 they did most of them by now. 669 After the work is done, you are required to test the branch 670 (before the merge to -current) with an interop IPv6 test. 671 More info at: http://www.tahi.org/ 672 673Branch: wrstuden-fixsa 674Description: Fix a number of issues present with Scheduler Activations. 675Status: Active 676Start Date: 15 May 2007 677End Date: 678Base Tag: wrstuden-fixsa-base 679Maintainer: Bill Stouder-Studenmund <wrstuden@NetBSD.org> 680Scope: src, though all the interesting stuff is in the kernel 681 or lib/libpthread or maybe gdb. 682Notes: This branch is based off of the netbsd-4 branch! 683 This branch is intended to stage improvements for the 684 Scheduler Activations system for NetBSD 4. Improvements 685 include not allocating memory while preparing to tsleep(), 686 reducing inappropriate upcall delivery (hopefully also 687 eliminating the need to mlock stacks), and being 688 able to pthread_kill() running threads. At this date, 689 most goals have been achieved.

In terms of UBC, the primary cache for 1640 file data is the VM cache, which needs to operate 1641 in terms of VM pages. As no existing device has native 1642 pages the same size as our VM pages, there already is 1643 a mapping going on between the VM system and the 1644 underlying blocks. So it would be easier and cleaner 1645 to adjust that to deal w/ different block sizes. 1646 Also with UBC, all i/o is in terms of bytes at an offset 1647 with a certain length, so the exact block size isn't a big 1648 deal. 1649 1650 Any other wrstuden-devbsize tag may (and should) go away. 1651 1652Branch: yamt-idlelwp 1653Description: idle lwp, and some changes depending on it. 1654 1655 1. separate context switching and thread scheduling. 1656 (cf. gmcgarry_ctxsw) 1657 2. implement idle lwp. 1658 3. clean up related MD/MI interfaces. 1659 4. make scheduler(s) modular. 1660 1661Status: Terminated; merged to -current 1662Start Date: Fri Feb 17 2007 1663End Date: Thu May 17 2007 1664Base Tag: yamt-idlelwp-base8 1665Maintainer: YAMAMOTO Takashi <yamt@NetBSD.org> 1666Scope: src/sys (src/common is tagged but not branched) 1667Notes: 1668 Status of ports: 1669 alpha [ Done, UP tested, MP not tested ] 1670 i386 [ Done, tested ] 1671 amd64 [ Done, tested ] 1672 mips [ Done, both MIPS1 and MIPS3 tested] 1673 sparc [ Done, UP tested, MP might have 1674 some problem after newlock2 merge ] 1675 sparc64 [ Done, tested ] 1676 arm [ Done, SA1 tested.
