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 initializtion, 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 245Branch: bjh21-hydra 246Description: Simtec Hydra support and ARM SMP in general 247Status: Dormant 248Start Date: 18 Oct 2002 249End Date: 250Base Tag: bjh21-hydra-base 251Maintainer: Ben Harris <bjh21@NetBSD.org> 252Scope: sys/arch/arm sys/arch/acorn32 253Notes: 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 257Branch: gmcgarry_ctxsw 258Description: Separate scheduler from context-switch code 259Status: Dormant 260Start Date: 18 December 2002 261End Date: 262Base Tag: gmcgarry_ctxsw_base 263Maintainer: Gregory McGarry <gmcgarry@NetBSD.org> 264Scope: kernel 265Notes: Removing knowledge of the schedular and its run queues 266 from the machine-dependent context switch code is the 267 first step in cleaning up the scheduler. It is necessary 268 for the newlock branch, making the scheduler SMP friendly, 269 adding real-time scheduler extensions, and reducing the 270 number of code paths for LWP and proc switching. 271 272Branch: gmcgarry_ucred 273Description: Integrate and encapsulate user credentials 274Status: Dormant 275Start Date: 18 December 2002 276End Date: 277Base Tag: gmcgarry_ucred_base 278Maintainer: Gregory McGarry <gmcgarry@NetBSD.org> 279Scope: kernel 280Notes: merge pcred and ucred and poolify 281 282Branch: kame 283Description: KAME Project 284Status: Dormant 285Start Date: 28 Jun 1999 286End Date: 287Base Tag: 288Maintainer: Jun-ichiro itojun Hagino <itojun@NetBSD.org> 289Scope: kernel 290Notes: http://www.kame.net 291 Used for "reference" purposes for early part of KAME 292 integration effort.

If you plan to 368 continue this branch, sys/netinet/in_pcb.h already contains 369 the proposed structure layout (which was roughly discussed 370 in the tech-net mailing list). 371 I also defined INP_*() macros to mimicate FreeBSD's inpcb 372 locking style, but currently they do nothing and are not 373 yet called at the correct places (needs discussion about 374 kernel fine-grained locking). 375 To continue this branch, one needs to read all the relevant 376 inpcb/in6pcb source files and change the function names, 377 structure names, structure fileds according to the new 378 layout (in6pcb is gone). 379 Don't try to build a kernel from this branch because it won't 380 work. The missing pieces required to do a complete build 381 were not committed because they were incomplete and generated 382 panics. 383 You shouldn't need to worry about KAME syncs because 384 they did most of them by now. 385 After the work is done, you are required to test the branch 386 (before the merge to -current) with an interop IPv6 test. 387 More info at: http://www.tahi.org/ 388 389Branch: rtr-xorg-branch 390Description: xorg & static build alterations to src/x11 391Status: Active 392Start Date: Nov 15 2004 393End Date: 394Base tag: rtr-xorg-branch-base 395Maintainer: Tyler R.

Most per architecture 421 changes need to be made in the pmap module. LFS is not 422 currently stable due interaction between the pagedaemon (?) 423 and the HOLDRELE() in lfs_segment.c. It may trash your 424 filesystem.. 425 426 Most of the locks replaced are now sleep/adaptive locks or 427 spin locks at IPL_VM. Assuming audio interrupt handlers 428 are made MP safe there are far fewer potential deadlocks 429 against the kernel lock. 430 431 v_interlock becomes an adaptive mutex so now acquring 432 it can potentially block, similarly for other locks 433 that were before simplelocks. This needs to be audited 434 carefully. 435 436 Use vnodes in general needs to be audited, as vnodes can 437 now be inspected without the kernel lock held. 438 439 Acquiring locks in the pmap module can now block, meaning 440 that the current pmap, cpu or lazy pmap status can change 441 out from underneath the requestor. This also needs to be 442 audited. 443 444 Currently, i386 has the necessary modifications, and has 445 trap handling and a few calls to allocators out from under 446 the kernel lock. There are still problems that need to be 447 debugged. 448 449 Need to check that whenever a lock is initialized, it is 450 also destroyed. 451 452 Lots of testing required. 453 454Branch: yamt-idlelwp 455Description: idle lwp, and some changes depending on it. 456 457 1. separate context switching and thread scheduling. 458 (cf. gmcgarry_ctxsw) 459 2. implement idle lwp. 460 3. clean up related MD/MI interfaces. 461 4. make scheduler(s) modular. 462 463Status: Active 464Start Date: Fri Feb 17 2007 465End Date: 466Base Tag: yamt-idlelwp-base5 467Maintainer: YAMAMOTO Takashi <yamt@NetBSD.org> 468Scope: src/sys (src/common is tagged but not branched) 469Notes: 470 Status of ports (minimal goals): 471 alpha [ Done, 472 UP tested, MP not tested ] 473 i386 [ Done, tested ] 474 amd64 [ Done, tested ] 475 mips [ WIP ] 476 sparc [ WIP ] 477 sparc64 [ WIP ] 478 arm [ Done. 479 SA1 tested. ] 480 macppc/powerpc [ Done, OEA tested ] 481 hppa [ WIP ] 482 sh3 [ Done, tested ] 483 vax [ Done, UP tested, MP untested ] 484 485 How to adapt a port?

So it would be easier and cleaner 1060 to adjust that to deal w/ different block sizes. 1061 Also with UBC, all i/o is in terms of bytes at an offset 1062 with a certain length, so the exact block size isn't a big 1063 deal. 1064 1065 Any other wrstuden-devbsize tag may (and should) go away. 1066 1067Branch: yamt-km, yamt-km-doc 1068Description: simplify/improve kernel memory management and bootstrap 1069Status: Terminated; merged to -current 1070Start Date: Tue Jan 25 2005 1071End Date: Fri Apr 1 2005 1072Base Tag: yamt-km-base{,2,3,4}, yamt-km-doc-base 1073Maintainer: YAMAMOTO Takashi <yamt@NetBSD.org> 1074Scope: yamt-km: src/sys 1075 yamt-km-doc: src/share/man/man9/uvm.9 1076Notes: http://mail-index.NetBSD.org/tech-kern/2004/12/25/0005.html 1077 1078 the followings are per-port status. 1079 (account names mean "tested by".) 1080 1081 works enough to go to multiuser: 1082 alpha, i386, xen (yamt@) 1083 pc532 (simonb@) 1084 alpha, i386, mac68k, macppc, pmax, shark, 1085 sparc, sparc64, sun3, x68k (chs@) 1086 cobalt, dreamcast, hp300, news68k, newsmips, 1087 sun3x (tsutsui@) 1088 amiga (mhitch@) 1089 cats, hp700 (skrll@) 1090 xen (bouyer@) 1091 1092 known to have the same problem as trunk: 1093 vax (chs@, stuck while running kvm_mkdb) 1094 1095 known to have a problem: 1096 luna68k (and, if any, other m68k ports which use TTR) 1097 needs to be revisited. 1098 -> for luna68k, although not tested, 1099 Sysmap has been moved to avoid kva conflict with 1100 I/O ranges. 1101 1102 buildable: 1103 src/sys/arch/acorn26/conf/GENERIC 1104 src/sys/arch/acorn32/conf/GENERIC 1105 src/sys/arch/algor/conf/P6032 1106 src/sys/arch/alpha/conf/GENERIC 1107 src/sys/arch/alpha/conf/GENERIC.MP 1108 src/sys/arch/amd64/conf/GENERIC 1109 src/sys/arch/amd64/conf/GENERIC.MP 1110 src/sys/arch/amiga/conf/GENERIC 1111 src/sys/arch/arc/conf/GENERIC 1112 src/sys/arch/atari/conf/MILAN-PCIIDE 1113 src/sys/arch/bebox/conf/GENERIC 1114 src/sys/arch/cats/conf/GENERIC 1115 src/sys/arch/cesfic/conf/GENERIC 1116 src/sys/arch/cobalt/conf/GENERIC 1117 src/sys/arch/dreamcast/conf/GENERIC 1118 src/sys/arch/evbarm/conf/TS7200 1119 src/sys/arch/evbppc/conf/WALNUT 1120 src/sys/arch/evbsh3/conf/COMPUTEXEVB 1121 src/sys/arch/evbsh5/conf/CAYMAN64 1122 src/sys/arch/hp300/conf/GENERIC 1123 src/sys/arch/hp700/conf/GENERIC 1124 src/sys/arch/hpcarm/conf/JORNADA728 1125 src/sys/arch/hpcmips/conf/GENERIC 1126 src/sys/arch/hpcsh/conf/GENERIC 1127 src/sys/arch/hpcsh/conf/HPW650PA 1128 src/sys/arch/i386/conf/GENERIC 1129 src/sys/arch/i386/conf/GENERIC.MP 1130 src/sys/arch/i386/conf/XEN0 1131 src/sys/arch/i386/conf/XENU 1132 src/sys/arch/ibmnws/conf/GENERIC 1133 src/sys/arch/iyonix/conf/GENERIC 1134 src/sys/arch/luna68k/conf/GENERIC 1135 src/sys/arch/mac68k/conf/GENERIC 1136 src/sys/arch/macppc/conf/GENERIC 1137 src/sys/arch/macppc/conf/GENERIC.MP 1138 src/sys/arch/mipsco/conf/GENERIC 1139 src/sys/arch/mmeye/conf/GENERIC 1140 src/sys/arch/mvme68k/conf/GENERIC 1141 src/sys/arch/netwinder/conf/GENERIC 1142 src/sys/arch/news68k/conf/GENERIC 1143 src/sys/arch/newsmips/conf/GENERIC 1144 src/sys/arch/next68k/conf/GENERIC 1145 src/sys/arch/ofppc/conf/GENERIC 1146 src/sys/arch/pc532/conf/GENERIC 1147 src/sys/arch/pmax/conf/GENERIC 1148 src/sys/arch/prep/conf/GENERIC 1149 src/sys/arch/sandpoint/conf/GENERIC 1150 src/sys/arch/sbmips/conf/GENERIC 1151 src/sys/arch/sgimips/conf/GENERIC32_IP3x 1152 src/sys/arch/shark/conf/GENERIC 1153 src/sys/arch/sparc/conf/GENERIC 1154 src/sys/arch/sparc/conf/GENERIC.MP 1155 src/sys/arch/sparc64/conf/GENERIC 1156 src/sys/arch/sparc64/conf/GENERIC.MP 1157 src/sys/arch/sun2/conf/GENERIC 1158 src/sys/arch/sun3/conf/GENERIC 1159 src/sys/arch/vax/conf/GENERIC 1160 src/sys/arch/vax/conf/GENERIC.MP 1161 src/sys/arch/x68k/conf/GENERIC 1162 1163 src/sys/arch/playstation2/conf/GENERIC 1164 1165Branch: yamt-pdpolicy 1166Description: play with page replacement policy 1167 - separate page replacement policy from the rest of kernel 1168 - implement alternative replacement policy 1169 - related read-ahead adjustment?
