Loongson 2F N32 stage3 is now available on gentoo mirrors

It is under experimental/mips/stages/loongson/. Like:
http://mirrors.xmu.edu.cn/gentoo/experimental/mips/stages/loongson/
I should have done it long ago, just don't familiar with catalyst and catalyst lacks documentation.

Thanks to leio and robbat2 for making it happen.

I have already included kernel modules in the stage3. You can find the corresponding kernel here:
http://www.gentoo-cn.org/~zhangle/

If you want to build your own kernel, use the source here:
http://dev.lemote.com/code/linux-loongson-community/wiki/WikiStart

You also need loongson overlay. Just use layman to add it. Of course you need to emerge layman first.
http://www.gentoo-cn.org/gitweb/?p=loongson.git;a=summary

If you find portage ask you to downgrade packages, you can try this trick
ACCEPT_KEYWORDS="x86 ~x86 ~mips"
However you need to understand that there is no guarantee that software installed in this way would work. But at least some of them will work. Like perl. I have been using this for a long time. Some packages are not so easy to downgrade. So maybe you need to use this too. But remember, if the package really works, better file a keyword bug asking devs to add mips keyword to it.

Please note this is experimental, so I am afraid there will be problems. If you hit any, please don't hesitate to contact me.

Type special characters in xterm in N900

UPDATE: The build failed because of gcc's multislot USE flag(seed stage has it while catalyst can't set USE for stage3). I was on a trip so there is actually no progress for the last 5 days. Sorry. I have worked around it. Now rebuilding.

First, sudo gainroot.

Then run the following two commands:
/home/user # gconftool-2 -s /apps/osso/xterm/key_labels -t list --list-type=string '[Tab,Esc,~,`,|,>,<]'
/home/user # gconftool-2 -s /apps/osso/xterm/keys -t list --list-type=string "[Tab,Escape,asciitilde,grave,bar,greater,less]"
Then restart your xterm, you will see the bottom bar looks like the one showing in the following picture:



This picture shows that I am building new stage3 for Loongson 2F, N32 ABI, ;)
