Chris Csandy offers these helpful tips on how to build a bridge.
Simon ‘corecode’ Schubert has added a change that makes cvs ask for confirmation before using a filename when adding a commit message.
As Matthew Dillon posted, SMP builds may be broken for the next few days, so rebuild with caution.
Matthew Dillon warned that he is committing a lot of work on multiprocessor support over the next few days; if you are one of the people who run bleeding-edge versions of DragonFly (1.5 from CVS, or ‘HEAD’), there will probably be some instability. It’s not called bleeding-edge for nothing…
BSD memory management systems are legendary for handling stress well; however, there’s a limit on how much paging can happen and still have a responsive system.Â Matthew Dillon has put in a possible improvment for low-memory solutions.
Sepherosa Ziehau has his version of the rtw(4) driver available for testing.Â This is taken fromt he NetBSD driver, and is used in newer wireless cards.
Matthew Dillon has found that an extended form of spinlock is useful for the MP goals he has to do before continuing his VFS work.
Matthew Dillon has removed support for ibcs2 and svr4 emulation.Â It hasn’t been touched in 10 years…Â Are there even binaries that still require that anymore?
Matthew Dillon has revamped the system include files in DragonFly, so now including the correct files is much simpler.
There were a number of interesting commits today: Sepherosa Ziehau’s new 802.11 framework, taken in part from FreeBSD 6, is now committed, and he’s also updated the man pages to match. (minor yet very important!) His ath(4) driver will be following soon. Also, Matthew Dillon has moved the LWKT from a token system to spinlocks – see the commit message for details. Finally, there are some side benefits for DragonFly from the Coverity scan of FreeBSD.
Matthew Dillon found some problems in his ongoing vnode work.Â Apparently, the way to solve them is to make other portions of the code multiprocessor safe.
