About 1/2 of the 372 drivers are converted, the remaining 1/2 need more changes. 373 374 As of import this is snapshot of work in progress and so 375 may not compile; in particular the midi changes are very 376 much "in progress". The audio component has been tested 377 and verified to work with emuxki and auvia. There may 378 be a locking issue in the ac97 code at boot. 379 380 The are two locks per device instance, an ISR lock and 381 a character device lock. The ISR lock replaces calls to 382 splaudio()/splx(), and will be held across calls to device 383 methods which were called at splaudio() before (e.g. 384 trigger_output). The character device lock is held across 385 calls to nearly all of the methods, excluding some only 386 used for initialization, e.g. get_locks. This needs to be 387 documented at merge time. 388 389 To test on a multi way x86 system, search for "mpsafe" in 390 x86/x86/intr.c and change IPL_SCHED to IPL_AUDIO. Run a job 391 that will acquire the ISR lock (depends on the hardware, but 392 "while true; do mixerctl -a > /dev/null; done" may suffice). 393 Play audio, run lockstat and verify that that there is 394 contention on the ISR lock. 395 396 Branch: ad-audiomp2 397 Description: Add MP locking to the audio drivers 398 Status: Terminated 399 Start Date: 7 December 2008 400 End Date: 19 November 2011 401 Base Tag: ad-audiomp2-base 402 Maintainer: Andrew Doran <ad (a] NetBSD.org> 403 Scope: kernel 404 Notes: Ressurect ad-audiomp, make the audio drivers MP safe. 405 406 Branch: ad-namecache 407 Description: Redo the namecache 408 Status: Active 409 Start Date: 8 January 2020 410 End Date: 411 Base Tag: ad-namecache-base 412 Maintainer: Andrew Doran <ad (a] NetBSD.org> 413 Scope: src/sys src/common 414 Notes: 1) Redo the namecache to focus on per-directory data 415 structures, removing the huge hashtable and nasty locking 416 scheme. 417 418 Initially this uses rbtrees (because that's what's there). 419 The intent is that ultimately some other data structure 420 will be used. 421 422 2) Experiment with having namei() traverse the cache and 423 avoid vnode locks except for the leaf in the totally 424 in-cache case. 425 426 Branch: agc-netpgp-standalone 427 Description: Remove dependency on openssl libraries in netpgp 428 Status: Active 429 Start Date: 5 May 2012 430 End Date: 431 Base Tag: agc-netpgp-standalone-base 432 Maintainer: Alistair Crooks <agc (a] NetBSD.org> 433 Scope: src/crypto/external/bsd/netpgp 434 Notes: This branch is used to develop the version of netpgp 435 which has its own version of bignum, ciphers, and signatures 436 libraries, so that it is able to operate without openssl 437 being in place. 438 439 Branch: agc-symver 440 Description: Add library symbol versioning information 441 Status: Active 442 Start Date: 24 March 2013 443 End Date: 444 Base Tag: agc-symver-base 445 Maintainer: Alistair Crooks <agc (a] NetBSD.org> 446 Scope: src 447 Notes: This branch is used to develop DSO symbol versioning, allowing 448 symbols to be added, modified and removed from shared libraries. 449 450 Branch: bjh21-hydra 451 Description: Simtec Hydra support and ARM SMP in general 452 Status: Dormant 453 Start Date: 18 Oct 2002 454 End Date: 455 Base Tag: bjh21-hydra-base 456 Maintainer: Ben Harris <bjh21 (a] NetBSD.org> 457 Scope: sys/arch/arm sys/arch/acorn32 458 Notes: This code was on a branch because it involves changes to 459 cpuswitch.S which would otherwise make merging the 460 nathanw_sa branch difficult. 461 462 Branch: bouyer-socketcan 463 Description: Implement a CAN socket layer compatible with linux SocketCAN 464 Status: Terminated 465 Start Date: Sun Jan 15 2017 466 End Date: May 27 2017 467 Base Tag: bouyer-socketcan-base 468 Maintainer: Manuel Bouyer <bouyer (a] NetBSD.org> 469 Scope: src/ 470 Notes: Some documentation on SocketCAN is there: 471 https://www.kernel.org/doc/Documentation/networking/can.txt 472 473 Branch: cherry-xenmp 474 Description: Port i386 and amd64 Xen kernels to run MP 475 Status: Terminated 476 Start Date: 1st June 2011 477 End Date: 13th January 2012 478 Base Tag: cherry-xenmp-base 479 Maintainer: Cherry G.

The missing pieces required to do a complete build 740 were not committed because they were incomplete and generated 741 panics. 742 You shouldn't need to worry about KAME syncs because 743 they did most of them by now. 744 After the work is done, you are required to test the branch 745 (before the merge to -current) with an interop IPv6 test. 746 More info at: http://www.tahi.org/ 747 748 Branch: thorpej-cfargs 749 Description: Clean up how arguments are passed to various autoconfiguration 750 routines. 751 Status: Merged 752 Start Date: Sat March 20 2021 753 End Date: Sat April 24 2021 754 Base Tag: thorpej-cfargs-base 755 Maintainer: Jason Thorpe <thorpej (a] netbsd.org> 756 Scope: src/sys 757 Notes: 758 759 Branch: thorpej-cfargs2 760 Description: Address complaints regarding the use of variadic arguments in 761 thorpej-cfargs. 762 Status: Merged 763 Start Date: Sun Aug 1 2021 764 End Date: Sat Aug 7 2021 765 Base Tag: thorpej-cfargs2-base 766 Maintainer: Jason Thorpe <thorpej (a] netbsd.org> 767 Scope: src/sys 768 Notes: 769 770 Branch: thorpej-futex 771 Description: Overhaul of futex operations to fix thread priority issues 772 Status: Partially merged 773 Start Date: Sun Nov 1 2020 774 End Date: Sun Aug 19 2021 775 Base Tag: thorpej-futex-base 776 Maintainer: Jason Thorpe <thorpej (a] netbsd.org> 777 Scope: src/sys src/tests/lib/libc/sys src/distrib/sets/lists 778 Notes: Normal futex operations pass the test suite, but there are 779 issues with Linux compatibility currently, that need to be 780 addressed before merging.

In terms of UBC, the primary cache for 1828 file data is the VM cache, which needs to operate 1829 in terms of VM pages. As no existing device has native 1830 pages the same size as our VM pages, there already is 1831 a mapping going on between the VM system and the 1832 underlying blocks. So it would be easier and cleaner 1833 to adjust that to deal w/ different block sizes. 1834 Also with UBC, all i/o is in terms of bytes at an offset 1835 with a certain length, so the exact block size isn't a big 1836 deal. 1837 1838 Any other wrstuden-devbsize tag may (and should) go away. 1839 1840 Branch: yamt-idlelwp 1841 Description: idle lwp, and some changes depending on it. 1842 1843 1. separate context switching and thread scheduling. 1844 (cf. gmcgarry_ctxsw) 1845 2. implement idle lwp. 1846 3. clean up related MD/MI interfaces. 1847 4. make scheduler(s) modular. 1848 1849 Status: Terminated; merged to -current 1850 Start Date: Fri Feb 17 2007 1851 End Date: Thu May 17 2007 1852 Base Tag: yamt-idlelwp-base8 1853 Maintainer: YAMAMOTO Takashi <yamt (a] NetBSD.org> 1854 Scope: src/sys (src/common is tagged but not branched) 1855 Notes: 1856 Status of ports: 1857 alpha [ Done, UP tested, MP not tested ] 1858 i386 [ Done, tested ] 1859 amd64 [ Done, tested ] 1860 mips [ Done, both MIPS1 and MIPS3 tested] 1861 sparc [ Done, UP tested, MP might have 1862 some problem after newlock2 merge ] 1863 sparc64 [ Done, tested ] 1864 arm [ Done, SA1 tested.
