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 662 continue this branch, sys/netinet/in_pcb.h already contains 663 the proposed structure layout (which was roughly discussed 664 in the tech-net mailing list). 665 I also defined INP_*() macros to mimicate FreeBSD's inpcb 666 locking style, but currently they do nothing and are not 667 yet called at the correct places (needs discussion about 668 kernel fine-grained locking). 669 To continue this branch, one needs to read all the relevant 670 inpcb/in6pcb source files and change the function names, 671 structure names, structure fields according to the new 672 layout (in6pcb is gone). 673 Don't try to build a kernel from this branch because it won't 674 work. The missing pieces required to do a complete build 675 were not committed because they were incomplete and generated 676 panics. 677 You shouldn't need to worry about KAME syncs because 678 they did most of them by now. 679 After the work is done, you are required to test the branch 680 (before the merge to -current) with an interop IPv6 test. 681 More info at: http://www.tahi.org/ 682 683Branch: wrstuden-fixsa 684Description: Fix a number of issues present with Scheduler Activations. 685Status: Active 686Start Date: 15 May 2007 687End Date: 688Base Tag: wrstuden-fixsa-base 689Maintainer: Bill Stouder-Studenmund <wrstuden@NetBSD.org> 690Scope: src, though all the interesting stuff is in the kernel 691 or lib/libpthread or maybe gdb. 692Notes: This branch is based off of the netbsd-4 branch! 693 This branch is intended to stage improvements for the 694 Scheduler Activations system for NetBSD 4.

In terms of UBC, the primary cache for 1658 file data is the VM cache, which needs to operate 1659 in terms of VM pages. As no existing device has native 1660 pages the same size as our VM pages, there already is 1661 a mapping going on between the VM system and the 1662 underlying blocks. So it would be easier and cleaner 1663 to adjust that to deal w/ different block sizes. 1664 Also with UBC, all i/o is in terms of bytes at an offset 1665 with a certain length, so the exact block size isn't a big 1666 deal. 1667 1668 Any other wrstuden-devbsize tag may (and should) go away. 1669 1670Branch: yamt-idlelwp 1671Description: idle lwp, and some changes depending on it. 1672 1673 1. separate context switching and thread scheduling. 1674 (cf. gmcgarry_ctxsw) 1675 2. implement idle lwp. 1676 3. clean up related MD/MI interfaces. 1677 4. make scheduler(s) modular. 1678 1679Status: Terminated; merged to -current 1680Start Date: Fri Feb 17 2007 1681End Date: Thu May 17 2007 1682Base Tag: yamt-idlelwp-base8 1683Maintainer: YAMAMOTO Takashi <yamt@NetBSD.org> 1684Scope: src/sys (src/common is tagged but not branched) 1685Notes: 1686 Status of ports: 1687 alpha [ Done, UP tested, MP not tested ] 1688 i386 [ Done, tested ] 1689 amd64 [ Done, tested ] 1690 mips [ Done, both MIPS1 and MIPS3 tested] 1691 sparc [ Done, UP tested, MP might have 1692 some problem after newlock2 merge ] 1693 sparc64 [ Done, tested ] 1694 arm [ Done, SA1 tested.

It is necessary 2048 for the newlock branch, making the scheduler SMP friendly, 2049 adding real-time scheduler extensions, and reducing the 2050 number of code paths for LWP and proc switching. 2051 2052Branch: nick-hppapmap 2053Description: Update of hppa pmap with OpenBSD code. 2054Status: Terminated; merged to -current 2055Start Date: 27 October 2008 2056End Date: 30 April 2009 2057Base Tag: nick-hppapmap-base3 2058Maintainer: Nick Hudson <skrll@NetBSD.org> 2059Scope: sys/ 2060Notes: Port of the OpenBSD pmap including support for PA2.0 CPUs in 2061 32-bit mode. 2062 2063Branch: thorpej-atomic 2064Description: Implementation of an atomic memory operations API modeled 2065 after the one in Solaris 10. 2066Status: Terminated; merged to -current 2067Start Date: Apr 11 2007 2068End Date: Nov 18 2007 2069Base tag: thorpej-atomic-base 2070Maintainer: Jason Thorpe <thorpej@netbsd.org> 2071Scope: src/common 2072 src/sys 2073Notes: Base atomic primitives need to be implemented for 2074 all of the supported architectures: 2075 2076 alpha DONE 2077 arm DONE 2078 hppa 2079 i386 DONE 2080 ia64 2081 m68k DONE (except for 68010) 2082 mips 2083 ns32k 2084 powerpc DONE except for membar_*() 2085 powerpc64 DONE except for membar_*() 2086 sh3 2087 sparc DONE except for membar_*() 2088 sparc64 DONE except for membar_*() 2089 vax 2090 x86_64 DONE 2091 2092 Tested: 2093 2094 alpha NO 2095 arm NO 2096 hppa NO 2097 i386 NO 2098 ia64 NO 2099 m68k NO 2100 mips NO 2101 ns32k NO 2102 powerpc NO 2103 powerpc64 NO 2104 sh3 NO 2105 sparc NO 2106 sparc64 NO 2107 vax NO 2108 x86_64 NO 2109 2110 TODO: 2111 2112 all - Need to replace mb_*() with membar_*(). 2113 2114 - Audit MUTEX_CAS() and RWLOCK_CAS() uses 2115 to see of membar_enter() is required here. 2116 2117 - Talk to ad@ -- figure out of non-atomic 2118 mutex / rwlock release is actually safe. 2119 2120 arm - Consider using a RAS technique like 2121 MIPS uses for _lock_cas() and the mutex 2122 stubs.
