Kernel

Matt Dillon has released the RC today. You can download the RC here:

http://www.dragonflybsd.org/main/download.cgi
ftp://ftp.dragonflybsd.org/iso-images/dfly-1.0RC1.iso.gz

Matt said that he will also announce this on FreeBSD list.

主要是空格的问题。我打算接下来的一段时间琢磨琢磨SoftUpdates，如果这个patch能commit的话，delphijfork的diff一下就能减少46K :-)

marcel has finally imported gdb into FreeBSD-base. Now we can debug kernels again.

niklas has committed the final SMP branch code, no more SMP branchs, we have SMP in OpenBSD-CURRENT now!!

I have posted it as rev. 1.5 of <research.delphij.net/freebsd/rfc3522.diff>. Some minor comestic changes has gone into the patchset, as junsu pointed out. I’ll remove the unrelated ones soon.

I have ported Jeffrey Hsu’s RFC3522 implementation in DragonFlyBSD to FreeBSD. Check https://research.delphij.net/freebsd/rfc3522.diff.

Now beastie.frontfree.net is running with HTT enabled.

I have noticed that today’s cvsup brings this to my local repo: src/sys/kern/kern_kse.c. From the version it seems to be from kern_thread.c. Waiting commitmail to explain this.

自从01年dillon commit之后一直就用着MAXUSERS 0。今天alu提到说MAXUSERS不合适的时候有可能会造成系统负荷能力下降，于是看了代码，发现MAXUSERS是根据内存大小算出来的，32-512之间。另外，实践证明MAXUSERS看来不能设置为2048(起不来)……

    You can actually run gdb on a live kernel like this:

    gdb -k /dev/mem /path/to/kernel.debug

    You can then use the 'proc' command to switch to a process (give it a
    pid), and do a stack backtrace.  That part only really works if the
    process is blocked on something (i.e. not running).

    But you can also dig around kernel globals and various data structures
    and that can be quite useful on a live system.
