The kernel crashed at last. But it didn't drop into gdb. I have set up a breakpoint at panic(), so it is not a panic. My speculation proved wrong, and I have no idea what went wrong here. I will give up for the time being. Gotta read some books and help to make the 32bit loongson port stable.

I have successfully run gorg on my loongson box. Find more info about gorg here: http://gentoo.neysx.org/mystuff/gorg/gorg.xml more info about loongson here: http://en.wikipedia.org/wiki/Loongson

最近在玩kgdb 似乎人们对于kgdb的热情不高 现在sf.net上cvs里的kgdb只能打在2.6.17内核上 目前的龙芯用的是2.6.18.1，好在要改动的地方不是很多，也不难 kgdb管理补丁用的是quilt，稍微看看man就明白了，用起来很方便 其实vanilla 2.6.18.1里也有一个kgdb选项，但实际上似乎是不能用的，连个断点都设置不了 之前我编的内核有两个问题，一个是网络传输速度慢，scp的时候经常断，如果用debian，速度恒定保持在2.x M/s，一个是字符界面在显示器上显示不出，显示器报告超出范围，debian里正常。我之前用的是从dev.lemote.com里checkout出来的内核代码里面自带的配置文件，稍做了改动。后来我用了debian的/proc/config.gz，就好了。可是我对比两个config也没看出有什么差异可以导致这两个问题。目前还是一个谜。 最后玩kgdb光靠串口来控制还是不行，现在continue之后，gdb里显示到free多少多少memory之后，就没有任何信息了，但是在显示器上可以看到实际上已经成功启动了。 kgdb真的很爽，如果想让目标机器的内核停止运行，并等待被开发机器上的gdb连接和控制，只需要在开发机器上执行 echo -e "\003" > /dev/ttyS1

Gentoo's mips64el toolchain(created by 'crossdev') support n32 by default. However, I want o32. Good news is I don't need mips64el, instead I need mipsel. Thanks to spbecker for pointing it out to me. I think mips64 here is the name of processor architecture. Apparently loongson doesn't belong to that category.

GB18030 charmap of redhat's glibc is different from that of GNU's glibc. I don't know exactly what this difference means to users. But I wonder why this difference exists. Get the former at http://sources.redhat.com/cgi-bin/cvsweb.cgi/libc/localedata/charmaps/?cvsroot=glibc Get the latter at http://www.gnu.org/software/libc/resources.html#projectweb I've created a diff which could be get here: http://robert.zhangle.googlepages.com/diff

In my opinion, a good community should treat new comers well. But some people think otherwise. http://www.gentoo.org/news/en/gwn/20061002-newsletter.xml#doc_chap3 (zhllg) i think many people like the idea installation could resume automatically when failure occur, is it possible with paludis? (mlangc) zhllg: http://www.paludis.org/faq.html#skipfirst  mlangc maskd masterdriverz maxauthority midnite__ mzli  mlangc maskd masterdriverz maxauthority midnite__ mzli (zhllg) mlangc, i've seen that actually, just wonder why, is it difficult to implement technically? (mlangc) i don't think so; as far as i know it is not implemented by __design__ - but you should better ask someone that actually works on paludis; i'm a simple user myself (rbrown`) zhllg: er no. Too unreliable, too flaky and far too widely abused; (zlin) zhllg: wouldn't it be much better to fix the packages that cause it to fail in the first place... (zhllg) zlin, yeah, from a developer's perspective *...
