BRANCHES revision 1.128 1 # $NetBSD: BRANCHES,v 1.128 2006/11/18 06:46:13 yamt Exp $
2 #
3 # This file contains a list of branches that exist in the NetBSD CVS
4 # tree and their current state.
5 #
6 # This list is necessarily incomplete.
7 #
8 # Within reason, developers may create branch and version tags at any
9 # time for any purpose. To avoid name collisions, private tags should
10 # have names which begin with the developer's NetBSD login name
11 # followed by a - or _ character (e.g., thorpej_scsipi,
12 # thorpej-signal)
13 #
14 # Any branch or version tag not listed here should be assumed to be
15 # private to the developer who created it. It is inappropriate for
16 # anyone other than that developer to commit, move tags, or otherwise
17 # modify the contents of the branch.
18 #
19 # Please update this file when a new branch is ready for consumption
20 # by folks other than the maintainer, or when the use or status of an
21 # existing branch changes significantly.
22 #
23 # Format:
24 # Branch: name of branch
25 # Description: Purpose and intention of the branch
26 # Status: Active/Terminated/Dormant
27 # Start Date: date first instantiated
28 # End Date: date it was Terminated/made_Dormant, if any
29 # Base Tag: netbsd-1-5-base, etc.
30 # Maintainer: Somebody to blame.
31 # Scope: Portion of the tree covered.
32 # Notes: Various other info, perhaps explanation of special tags,
33 # who-may-commit policies, etc.
34 #
35 # There are four sections to this file:
36 # Release branches
37 # Individual developers' branches (Active/Dormant)
38 # Individual developers' branches (Terminated), and
39 # other
40 #
41 # Entries within each section should be alphabetized.

211 Branch: bjh21-hydra
212 Description: Simtec Hydra support and ARM SMP in general
213 Status: Dormant
214 Start Date: 18 Oct 2002
215 End Date:
216 Base Tag: bjh21-hydra-base
217 Maintainer: Ben Harris <bjh21 (a] NetBSD.org>
218 Scope: sys/arch/arm sys/arch/acorn32
219 Notes: This code was on a branch because it involves changes to
220 cpuswitch.S which would otherwise make merging the
221 nathanw_sa branch difficult.
222
223 Branch: gmcgarry_ctxsw
224 Description: Separate scheduler from context-switch code
225 Status: Dormant
226 Start Date: 18 December 2002
227 End Date:
228 Base Tag: gmcgarry_ctxsw_base
229 Maintainer: Gregory McGarry <gmcgarry (a] NetBSD.org>
230 Scope: kernel
231 Notes: Removing knowledge of the schedular and its run queues
232 from the machine-dependent context switch code is the
233 first step in cleaning up the scheduler. It is necessary
234 for the newlock branch, making the scheduler SMP friendly,
235 adding real-time scheduler extensions, and reducing the
236 number of code paths for LWP and proc switching.
237
238 Branch: gmcgarry_ucred

302 Base Tag: newlock2-base
303 Maintainer: Andrew Doran <ad (a] NetBSD.org>
304 Scope: Kernel
305 Notes: As per the newlock branch, however given the amount of time
306 the original branch has lain dormant, a new one has been
307 created. Goals:
308 - Implement new locking primitives on most-used ports.
309 - Minor locking improvements.
310 - Remove spinlockmgr().

603 Notes: Integration of FreeBSD's kqueue(2) mechanism, with various
604 local internal changes to better suit NetBSD, and
605 enhancements such as looking up filters by name or
606 number, and dynamic registration of "user" filters.
607 The work is complete as is, but is awaiting more
608 feedback from various kernel gurus before going mainline.

746 Not guaranteed to compile against mainline since -current

756 Note that this branch uses a DIFFERENT scheme for
757 synching with the mainline. the maintainer uses some private
758 scripts for keeping them in synch; if you make commits
759 to the branch to "resynchronize" things, you'll
760 probably do it wrong; instead, ask the maintainer to
761 resynchronize things.

888 Maintainer: Bill Studenmund <wrstuden (a] NetBSD.org>
889 Scope: kernel
890 Notes: No longer active due to lack of time, and introduction
891 of UBC. In terms of UBC, the primary cache for
892 file data is the VM cache, which needs to operate
893 in terms of VM pages. As no existing device has native
894 pages the same size as our VM pages, there already is
895 a mapping going on between the VM system and the
896 underlying blocks. So it would be easier and cleaner
897 to adjust that to deal w/ different block sizes.
898 Also with UBC, all i/o is in terms of bytes at an offset
899 with a certain length, so the exact block size isn't a big
900 deal.
901
902 Any other wrstuden-devbsize tag may (and should) go away.
