About 1/2 of the 316 drivers are converted, the remaining 1/2 need more changes. 317 318 As of import this is snapshot of work in progress and so 319 may not compile; in particular the midi changes are very 320 much "in progress". The audio component has been tested 321 and verified to work with emuxki and auvia. There may 322 be a locking issue in the ac97 code at boot. 323 324 The are two locks per device instance, an ISR lock and 325 a character device lock. The ISR lock replaces calls to 326 splaudio()/splx(), and will be held across calls to device 327 methods which were called at splaudio() before (e.g. 328 trigger_output). The character device lock is held across 329 calls to nearly all of the methods, excluding some only 330 used for initialization, e.g. get_locks. This needs to be 331 documented at merge time. 332 333 To test on a multi way x86 system, search for "mpsafe" in 334 x86/x86/intr.c and change IPL_SCHED to IPL_AUDIO. Run a job 335 that will acquire the ISR lock (depends on the hardware, but 336 "while true; do mixerctl -a > /dev/null; done" may suffice). 337 Play audio, run lockstat and verify that that there is 338 contention on the ISR lock. 339 340Branch: ad-audiomp2 341Description: Add MP locking to the audio drivers 342Status: Terminated 343Start Date: 7 December 2008 344End Date: 19 November 2011 345Base Tag: ad-audiomp2-base 346Maintainer: Andrew Doran <ad@NetBSD.org> 347Scope: kernel 348Notes: Ressurect ad-audiomp, make the audio drivers MP safe. 349 350Branch: agc-netpgp-standalone 351Description: Remove dependency on openssl libraries in netpgp 352Status: Active 353Start Date: 5 May 2012 354End Date: 355Base Tag: agc-netpgp-standalone-base 356Maintainer: Alistair Crooks <agc@NetBSD.org> 357Scope: src/crypto/external/bsd/netpgp 358Notes: This branch is used to develop the version of netpgp 359 which has its own version of bignum, ciphers, and signatures 360 libraries, so that it is able to operate without openssl 361 being in place. 362 363Branch: agc-symver 364Description: Add library symbol versioning information 365Status: Active 366Start Date: 24 March 2013 367End Date: 368Base Tag: agc-symver-base 369Maintainer: Alistair Crooks <agc@NetBSD.org> 370Scope: src 371Notes: This branch is used to develop DSO symbol versioning, allowing 372 symbols to be added, modified and removed from shared libraries. 373 374Branch: bjh21-hydra 375Description: Simtec Hydra support and ARM SMP in general 376Status: Dormant 377Start Date: 18 Oct 2002 378End Date: 379Base Tag: bjh21-hydra-base 380Maintainer: Ben Harris <bjh21@NetBSD.org> 381Scope: sys/arch/arm sys/arch/acorn32 382Notes: This code was on a branch because it involves changes to 383 cpuswitch.S which would otherwise make merging the 384 nathanw_sa branch difficult. 385 386Branch: cherry-xenmp 387Description: Port i386 and amd64 Xen kernels to run MP 388Status: Terminated 389Start Date: 1st June 2011 390End Date: 13th January 2012 391Base Tag: cherry-xenmp-base 392Maintainer: Cherry G.

If you plan to 629 continue this branch, sys/netinet/in_pcb.h already contains 630 the proposed structure layout (which was roughly discussed 631 in the tech-net mailing list). 632 I also defined INP_*() macros to mimicate FreeBSD's inpcb 633 locking style, but currently they do nothing and are not 634 yet called at the correct places (needs discussion about 635 kernel fine-grained locking). 636 To continue this branch, one needs to read all the relevant 637 inpcb/in6pcb source files and change the function names, 638 structure names, structure fields according to the new 639 layout (in6pcb is gone). 640 Don't try to build a kernel from this branch because it won't 641 work. The missing pieces required to do a complete build 642 were not committed because they were incomplete and generated 643 panics. 644 You shouldn't need to worry about KAME syncs because 645 they did most of them by now. 646 After the work is done, you are required to test the branch 647 (before the merge to -current) with an interop IPv6 test. 648 More info at: http://www.tahi.org/ 649 650Branch: wrstuden-fixsa 651Description: Fix a number of issues present with Scheduler Activations. 652Status: Active 653Start Date: 15 May 2007 654End Date: 655Base Tag: wrstuden-fixsa-base 656Maintainer: Bill Stouder-Studenmund <wrstuden@NetBSD.org> 657Scope: src, though all the interesting stuff is in the kernel 658 or lib/libpthread or maybe gdb. 659Notes: This branch is based off of the netbsd-4 branch! 660 This branch is intended to stage improvements for the 661 Scheduler Activations system for NetBSD 4. Improvements 662 include not allocating memory while preparing to tsleep(), 663 reducing inappropriate upcall delivery (hopefully also 664 eliminating the need to mlock stacks), and being 665 able to pthread_kill() running threads. At this date, 666 most goals have been achieved. This branch also includes 667 fixes to gdb to support working with threaded apps. 668 669Branch: wrstuden-revivesa 670Description: Fix a number of issues present with Scheduler Activations. 671Status: Active 672Start Date: 10 May 2008 673End Date: 674Base Tag: wrstuden-revivesa-base 675Maintainer: Bill Stouder-Studenmund <wrstuden@NetBSD.org> 676Scope: src, though all the interesting stuff is in the kernel 677Notes: This branch is intended to revive Scheduler Activations 678 in -current in the 5.0 era. This branch's main goal is 679 to re-add syscall compatability so that SA-based libpthread 680 programs can run with a -current kernel. 1:1 threading will 681 remain the NetBSD-default. This branch will re-add necessary 682 upcall support, and will also serve as a chance to clean 683 out cruft that had accumulated in the implementation over 684 time. 685 686Branch: yamt-kmem 687Description: 688 - separate kernel va allocation from kernel fault handling. 689 - make kmem_alloc interrupt-safe. 690Status: Active 691Start Date: Sun Dec 9 2007 692End Date: 693Base Tag: yamt-kmem-base3 694Maintainer: YAMAMOTO Takashi <yamt@NetBSD.org> 695Scope: src/sys (src/common is tagged but not branched) 696Notes: 697 todo: 698 - investigate if PMAP_PREFER equivalent can be done 699 with vmem_xalloc. find a tester with hardware for it. 700 - g/c replaced code, including kmapent and malloc. 701 - consider to remove other submaps. eg. mb_map 702 703Branch: yamt-nfs-mp 704Description: make nfs client mp-safe 705Status: Active 706Start Date: Sun Apr 27 2008 707End Date: 708Base Tag: yamt-nfs-mp-base11 709Maintainer: YAMAMOTO Takashi <yamt@NetBSD.org> 710Scope: src/sys (src/common is tagged but not branched) 711Notes: 712 713Branch: yamt-pagecache 714Description: page cache related changes 715Status: Active 716Start Date: Wed Nov 2 2011 717End Date: 718Base Tag: yamt-pagecache-base8 719Maintainer: YAMAMOTO Takashi <yamt@NetBSD.org> 720Scope: src 721Notes: - maintain object pages in radix tree rather than rb tree. 722 - shrink the size of vm_page. 723 - reduce unnecessary page scan in putpages. esp. when an 724 object has a ton of pages cached but only a few of them 725 are dirty. 726 - reduce the number of pmap operations by tracking page 727 dirtiness more precisely in uvm layer. 728 - fix nfs commit range tracking. 729 - fix nfs write clustering.

So it would be easier and cleaner 1594 to adjust that to deal w/ different block sizes. 1595 Also with UBC, all i/o is in terms of bytes at an offset 1596 with a certain length, so the exact block size isn't a big 1597 deal. 1598 1599 Any other wrstuden-devbsize tag may (and should) go away. 1600 1601Branch: yamt-idlelwp 1602Description: idle lwp, and some changes depending on it. 1603 1604 1. separate context switching and thread scheduling. 1605 (cf. gmcgarry_ctxsw) 1606 2. implement idle lwp. 1607 3. clean up related MD/MI interfaces. 1608 4. make scheduler(s) modular. 1609 1610Status: Terminated; merged to -current 1611Start Date: Fri Feb 17 2007 1612End Date: Thu May 17 2007 1613Base Tag: yamt-idlelwp-base8 1614Maintainer: YAMAMOTO Takashi <yamt@NetBSD.org> 1615Scope: src/sys (src/common is tagged but not branched) 1616Notes: 1617 Status of ports: 1618 alpha [ Done, UP tested, MP not tested ] 1619 i386 [ Done, tested ] 1620 amd64 [ Done, tested ] 1621 mips [ Done, both MIPS1 and MIPS3 tested] 1622 sparc [ Done, UP tested, MP might have 1623 some problem after newlock2 merge ] 1624 sparc64 [ Done, tested ] 1625 arm [ Done, SA1 tested.
