About 1/2 of the 221 drivers are converted, the remaining 1/2 need more changes. 222 223 As of import this is snapshot of work in progress and so 224 may not compile; in particular the midi changes are very 225 much "in progress". The audio component has been tested 226 and verified to work with emuxki and auvia. There may 227 be a locking issue in the ac97 code at boot. 228 229 The are two locks per device instance, an ISR lock and 230 a character device lock. The ISR lock replaces calls to 231 splaudio()/splx(), and will be held across calls to device 232 methods which were called at splaudio() before (e.g. 233 trigger_output). The character device lock is held across 234 calls to nearly all of the methods, excluding some only 235 used for initialization, e.g. get_locks. This needs to be 236 documented at merge time. 237 238 To test on a multi way x86 system, search for "mpsafe" in 239 x86/x86/intr.c and change IPL_SCHED to IPL_AUDIO. Run a job 240 that will acquire the ISR lock (depends on the hardware, but 241 "while true; do mixerctl -a > /dev/null; done" may suffice). 242 Play audio, run lockstat and verify that that there is 243 contention on the ISR lock. 244 245 Branch: bjh21-hydra 246 Description: Simtec Hydra support and ARM SMP in general 247 Status: Dormant 248 Start Date: 18 Oct 2002 249 End Date: 250 Base Tag: bjh21-hydra-base 251 Maintainer: Ben Harris <bjh21 (a] NetBSD.org> 252 Scope: sys/arch/arm sys/arch/acorn32 253 Notes: This code was on a branch because it involves changes to 254 cpuswitch.S which would otherwise make merging the 255 nathanw_sa branch difficult. 256 257 Branch: chris-arm-intr-rework 258 Description: Rework arm interrupt handling code 259 Status: Active 260 Start Date: 11 Aug 2007 261 End Date: 262 Base Tag: chris-arm-intr-rework-base 263 Maintainer: Chris Gilbert <chris (a] NetBSD.org> 264 Scope: sys/arch/arm sys/arch/cats (other arm archs to follow) 265 Notes: Rework arm interrupt code to provide a shared set of interrupt 266 routines, and allow improvements to be shared across all arm 267 based hardware. 268 269 Branch: cube-autoconf 270 Description: Renovate autoconf(9) API 271 Status: Active 272 Start Date: 11 Dec 2007 273 End Date: 274 Base Tag: cube-autoconf-base 275 Maintainer: Quentin Garnier <cube (a] NetBSD.org> 276 Scope: kernel usr.bin/config (and some other userland bits) 277 Notes: Address a number of issues the current autoconf(9) API has. 278 279 Branch: gmcgarry_ctxsw 280 Description: Separate scheduler from context-switch code 281 Status: Dormant 282 Start Date: 18 December 2002 283 End Date: 284 Base Tag: gmcgarry_ctxsw_base 285 Maintainer: Gregory McGarry <gmcgarry (a] NetBSD.org> 286 Scope: kernel 287 Notes: Removing knowledge of the scheduler and its run queues 288 from the machine-dependent context switch code is the 289 first step in cleaning up the scheduler.

If you plan to 468 continue this branch, sys/netinet/in_pcb.h already contains 469 the proposed structure layout (which was roughly discussed 470 in the tech-net mailing list). 471 I also defined INP_*() macros to mimicate FreeBSD's inpcb 472 locking style, but currently they do nothing and are not 473 yet called at the correct places (needs discussion about 474 kernel fine-grained locking). 475 To continue this branch, one needs to read all the relevant 476 inpcb/in6pcb source files and change the function names, 477 structure names, structure fields according to the new 478 layout (in6pcb is gone). 479 Don't try to build a kernel from this branch because it won't 480 work. The missing pieces required to do a complete build 481 were not committed because they were incomplete and generated 482 panics. 483 You shouldn't need to worry about KAME syncs because 484 they did most of them by now. 485 After the work is done, you are required to test the branch 486 (before the merge to -current) with an interop IPv6 test. 487 More info at: http://www.tahi.org/ 488 489 Branch: rtr-xorg-branch 490 Description: xorg & static build alterations to src/x11 491 Status: Active 492 Start Date: Nov 15 2004 493 End Date: 494 Base tag: rtr-xorg-branch-base 495 Maintainer: Tyler R.

Improvements 517 include not allocating memory while preparing to tsleep(), 518 reducing inappropriate upcall delivery (hopefully also 519 eliminating the need to mlock stacks), and being 520 able to pthread_kill() running threads. At this date, 521 most goals have been achieved. This branch also includes 522 fixes to gdb to support working with threaded apps. 523 524 Branch: wrstuden-revivesa 525 Description: Fix a number of issues present with Scheduler Activations. 526 Status: Active 527 Start Date: 10 May 2008 528 End Date: 529 Base Tag: wrstuden-revivesa-base 530 Maintainer: Bill Stouder-Studenmund <wrstuden (a] NetBSD.org> 531 Scope: src, though all the interesting stuff is in the kernel 532 Notes: This branch is intended to revive Scheduler Activations 533 in -current in the 5.0 era. This branch's main goal is 534 to re-add syscall compatability so that SA-based libpthread 535 programs can run with a -current kernel. 1:1 threading will 536 remain the NetBSD-default. This branch will re-add necessary 537 upcall support, and will also serve as a chance to clean 538 out cruft that had accumulated in the implementation over 539 time. 540 541 Branch: yamt-kmem 542 Description: 543 - separate kernel va allocation from kernel fault handling. 544 - make kmem_alloc interrupt-safe. 545 Status: Active 546 Start Date: Sun Dec 9 2007 547 End Date: 548 Base Tag: yamt-kmem-base3 549 Maintainer: YAMAMOTO Takashi <yamt (a] NetBSD.org> 550 Scope: src/sys (src/common is tagged but not branched) 551 Notes: 552 todo: 553 - investigate if PMAP_PREFER equivalent can be done 554 with vmem_xalloc. find a tester with hardware for it. 555 - g/c replaced code, including kmapent and malloc. 556 - consider to remove other submaps. eg. mb_map 557 558 Branch: yamt-nfs-mp 559 Description: make nfs client mp-safe 560 Status: Active 561 Start Date: Sun Apr 27 2008 562 End Date: 563 Base Tag: yamt-nfs-mp-base2 564 Maintainer: YAMAMOTO Takashi <yamt (a] NetBSD.org> 565 Scope: src/sys (src/common is tagged but not branched) 566 Notes: 567 568 Branch: reinoud-bufcleanup 569 Description: implement and evaluate struct buf usage cleanup strategies. 570 Ideas currently in mind (preference for b): 571 a) 572 1. use of bio_ops per buffer. 573 2. allow chaining/overloading of functions in bio_ops 574 and provide some private context. 575 3. extend the bio_ops with commonly used functionality 576 like pending action counting, custom context passing, 577 last minute processing of buffer data, buffer cache 578 etc. 579 4. investigate the use of the kcont() 580 continuation-passing framework for async io 581 completion notification for bufs 582 ... 583 b) 584 1. all sequencing use of B_CALL replaced by 585 device-threads, if possible generic code around BUFQ 586 2. possibly use kcont() for async IO finished signaling 587 3. counter of pending and queued actions requestable 588 by IOCTL interface? 589 4. implement `last minute buffer fixup' calls and maybe 590 even finished I/O calls as vnode operations 591 ... 592 Status: Active 593 Start Date: Thu Mar 15 2007 594 End Date: 595 Base Tag: reinoud-bufcleanup-base 596 Maintainer: Reinoud Zandijk <reinoud (a] NetBSD.org> 597 Scope: src/sys and src/common 598 Notes: Used as experiment sandbox and if successful hopefully one day 599 to be integrated. 600 601 Branch: simonb-wapbl 602 Description: Wasabi's journaling filesystem support 603 Status: Active 604 Start Date: Tue Jun 10 2008 605 End Date: 606 Base Tag: simonb-wapbl-base 607 Maintainer: Simon Burge <simonb (a] NetBSD.org> 608 Scope: src/distrib/sets/lists/comp src/distrib/utils/sysinst 609 src/include 610 src/sbin/fsck_ffs src/sbin/fsdb src/sbin/mount_ffs 611 src/sbin/tunefs src/usr.sbin/dumpfs src/sys 612 Notes: Still has a number of issues: 613 - Some heavy workload performance issues on SMP machines. 614 Work around this issue by turning on WAPBL_DEBUG_SERIALIZE 615 in rev 1.1.2.11 of vfs_wapbl.c. 616 - Removing large files (sparse only?) takes a long time. 617 Eg, a file created with 618 dd if=/dev/zero of=foox bs=1 count=1 seek=11261748520550 619 takes 0:00.00 to remove on my test box without logging and 620 0:22.25 to remove with logging.

In terms of UBC, the primary cache for 1293 file data is the VM cache, which needs to operate 1294 in terms of VM pages. As no existing device has native 1295 pages the same size as our VM pages, there already is 1296 a mapping going on between the VM system and the 1297 underlying blocks. So it would be easier and cleaner 1298 to adjust that to deal w/ different block sizes. 1299 Also with UBC, all i/o is in terms of bytes at an offset 1300 with a certain length, so the exact block size isn't a big 1301 deal. 1302 1303 Any other wrstuden-devbsize tag may (and should) go away. 1304 1305 Branch: yamt-idlelwp 1306 Description: idle lwp, and some changes depending on it. 1307 1308 1. separate context switching and thread scheduling. 1309 (cf. gmcgarry_ctxsw) 1310 2. implement idle lwp. 1311 3. clean up related MD/MI interfaces. 1312 4. make scheduler(s) modular. 1313 1314 Status: Terminated; merged to -current 1315 Start Date: Fri Feb 17 2007 1316 End Date: Thu May 17 2007 1317 Base Tag: yamt-idlelwp-base8 1318 Maintainer: YAMAMOTO Takashi <yamt (a] NetBSD.org> 1319 Scope: src/sys (src/common is tagged but not branched) 1320 Notes: 1321 Status of ports: 1322 alpha [ Done, UP tested, MP not tested ] 1323 i386 [ Done, tested ] 1324 amd64 [ Done, tested ] 1325 mips [ Done, both MIPS1 and MIPS3 tested] 1326 sparc [ Done, UP tested, MP might have 1327 some problem after newlock2 merge ] 1328 sparc64 [ Done, tested ] 1329 arm [ Done, SA1 tested.
