About 1/2 of the 361 drivers are converted, the remaining 1/2 need more changes. 362 363 As of import this is snapshot of work in progress and so 364 may not compile; in particular the midi changes are very 365 much "in progress". The audio component has been tested 366 and verified to work with emuxki and auvia. There may 367 be a locking issue in the ac97 code at boot. 368 369 The are two locks per device instance, an ISR lock and 370 a character device lock. The ISR lock replaces calls to 371 splaudio()/splx(), and will be held across calls to device 372 methods which were called at splaudio() before (e.g. 373 trigger_output). The character device lock is held across 374 calls to nearly all of the methods, excluding some only 375 used for initialization, e.g. get_locks. This needs to be 376 documented at merge time. 377 378 To test on a multi way x86 system, search for "mpsafe" in 379 x86/x86/intr.c and change IPL_SCHED to IPL_AUDIO. Run a job 380 that will acquire the ISR lock (depends on the hardware, but 381 "while true; do mixerctl -a > /dev/null; done" may suffice). 382 Play audio, run lockstat and verify that that there is 383 contention on the ISR lock. 384 385Branch: ad-audiomp2 386Description: Add MP locking to the audio drivers 387Status: Terminated 388Start Date: 7 December 2008 389End Date: 19 November 2011 390Base Tag: ad-audiomp2-base 391Maintainer: Andrew Doran <ad@NetBSD.org> 392Scope: kernel 393Notes: Ressurect ad-audiomp, make the audio drivers MP safe. 394 395Branch: ad-namecache 396Description: Redo the namecache 397Status: Active 398Start Date: 8 January 2020 399End Date: 400Base Tag: ad-namecache-base 401Maintainer: Andrew Doran <ad@NetBSD.org> 402Scope: src/sys src/common 403Notes: 1) Redo the namecache to focus on per-directory data 404 structures, removing the huge hashtable and nasty locking 405 scheme. 406 407 Initially this uses rbtrees (because that's what's there). 408 The intent is that ultimately some other data structure 409 will be used. 410 411 2) Experiment with having namei() traverse the cache and 412 avoid vnode locks except for the leaf in the totally 413 in-cache case. 414 415Branch: agc-netpgp-standalone 416Description: Remove dependency on openssl libraries in netpgp 417Status: Active 418Start Date: 5 May 2012 419End Date: 420Base Tag: agc-netpgp-standalone-base 421Maintainer: Alistair Crooks <agc@NetBSD.org> 422Scope: src/crypto/external/bsd/netpgp 423Notes: This branch is used to develop the version of netpgp 424 which has its own version of bignum, ciphers, and signatures 425 libraries, so that it is able to operate without openssl 426 being in place. 427 428Branch: agc-symver 429Description: Add library symbol versioning information 430Status: Active 431Start Date: 24 March 2013 432End Date: 433Base Tag: agc-symver-base 434Maintainer: Alistair Crooks <agc@NetBSD.org> 435Scope: src 436Notes: This branch is used to develop DSO symbol versioning, allowing 437 symbols to be added, modified and removed from shared libraries. 438 439Branch: bjh21-hydra 440Description: Simtec Hydra support and ARM SMP in general 441Status: Dormant 442Start Date: 18 Oct 2002 443End Date: 444Base Tag: bjh21-hydra-base 445Maintainer: Ben Harris <bjh21@NetBSD.org> 446Scope: sys/arch/arm sys/arch/acorn32 447Notes: This code was on a branch because it involves changes to 448 cpuswitch.S which would otherwise make merging the 449 nathanw_sa branch difficult. 450 451Branch: bouyer-socketcan 452Description: Implement a CAN socket layer compatible with linux SocketCAN 453Status: Terminated 454Start Date: Sun Jan 15 2017 455End Date: May 27 2017 456Base Tag: bouyer-socketcan-base 457Maintainer: Manuel Bouyer <bouyer@NetBSD.org> 458Scope: src/ 459Notes: Some documentation on SocketCAN is there: 460 https://www.kernel.org/doc/Documentation/networking/can.txt 461 462Branch: cherry-xenmp 463Description: Port i386 and amd64 Xen kernels to run MP 464Status: Terminated 465Start Date: 1st June 2011 466End Date: 13th January 2012 467Base Tag: cherry-xenmp-base 468Maintainer: Cherry G.

If you plan to 716 continue this branch, sys/netinet/in_pcb.h already contains 717 the proposed structure layout (which was roughly discussed 718 in the tech-net mailing list). 719 I also defined INP_*() macros to mimicate FreeBSD's inpcb 720 locking style, but currently they do nothing and are not 721 yet called at the correct places (needs discussion about 722 kernel fine-grained locking). 723 To continue this branch, one needs to read all the relevant 724 inpcb/in6pcb source files and change the function names, 725 structure names, structure fields according to the new 726 layout (in6pcb is gone). 727 Don't try to build a kernel from this branch because it won't 728 work. The missing pieces required to do a complete build 729 were not committed because they were incomplete and generated 730 panics. 731 You shouldn't need to worry about KAME syncs because 732 they did most of them by now. 733 After the work is done, you are required to test the branch 734 (before the merge to -current) with an interop IPv6 test. 735 More info at: http://www.tahi.org/ 736 737Branch: thorpej-cfargs 738Description: Clean up how arguments are passed to various autoconfiguration 739 routines. 740Status: Merged 741Start Date: Sat March 20 2021 742End Date: Sat April 24 2021 743Base Tag: thorpej-cfargs-base 744Maintainer: Jason Thorpe <thorpej@netbsd.org> 745Scope: src/sys 746Notes: 747 748Branch: thorpej-cfargs2 749Description: Address complaints regarding the use of variadic arguments in 750 thorpej-cfargs. 751Status: Merged 752Start Date: Sun Aug 1 2021 753End Date: Sat Aug 7 2021 754Base Tag: thorpej-cfargs2-base 755Maintainer: Jason Thorpe <thorpej@netbsd.org> 756Scope: src/sys 757Notes: 758 759Branch: thorpej-futex 760Description: Overhaul of futex operations to fix thread priority issues 761Status: Partially merged 762Start Date: Sun Nov 1 2020 763End Date: Sun Aug 19 2021 764Base Tag: thorpej-futex-base 765Maintainer: Jason Thorpe <thorpej@netbsd.org> 766Scope: src/sys src/tests/lib/libc/sys src/distrib/sets/lists 767Notes: Normal futex operations pass the test suite, but there are 768 issues with Linux compatibility currently, that need to be 769 addressed before merging.

In terms of UBC, the primary cache for 1817 file data is the VM cache, which needs to operate 1818 in terms of VM pages. As no existing device has native 1819 pages the same size as our VM pages, there already is 1820 a mapping going on between the VM system and the 1821 underlying blocks. So it would be easier and cleaner 1822 to adjust that to deal w/ different block sizes. 1823 Also with UBC, all i/o is in terms of bytes at an offset 1824 with a certain length, so the exact block size isn't a big 1825 deal. 1826 1827 Any other wrstuden-devbsize tag may (and should) go away. 1828 1829Branch: yamt-idlelwp 1830Description: idle lwp, and some changes depending on it. 1831 1832 1. separate context switching and thread scheduling. 1833 (cf. gmcgarry_ctxsw) 1834 2. implement idle lwp. 1835 3. clean up related MD/MI interfaces. 1836 4. make scheduler(s) modular. 1837 1838Status: Terminated; merged to -current 1839Start Date: Fri Feb 17 2007 1840End Date: Thu May 17 2007 1841Base Tag: yamt-idlelwp-base8 1842Maintainer: YAMAMOTO Takashi <yamt@NetBSD.org> 1843Scope: src/sys (src/common is tagged but not branched) 1844Notes: 1845 Status of ports: 1846 alpha [ Done, UP tested, MP not tested ] 1847 i386 [ Done, tested ] 1848 amd64 [ Done, tested ] 1849 mips [ Done, both MIPS1 and MIPS3 tested] 1850 sparc [ Done, UP tested, MP might have 1851 some problem after newlock2 merge ] 1852 sparc64 [ Done, tested ] 1853 arm [ Done, SA1 tested.
