fun around MIPS: qemu-system-mips
Posted 11-06-2010 at 10:33 PM by Web31337
Yesterday I was surprised when discovered that,... ehm, well... I'm such a newbie in this... that most routers using MIPS not ARM CPU as I thought before 
Since that, I've also tried to look at MIPS in QEMU. There is even less information about this, though debian to help I was surprised I've missed it last time when doing experiments with qemu-system-arm, but now it's very helpful with qemu-system-mips.
I used aurel32's page as a start point: http://people.debian.org/~aurel32/qemu/mips/
It went really good, I booted into lenny with no problems, then I've updated packages in that disk image and my next stop was this: http://ftp.us.debian.org/debian/pool/main/l/linux-2.6/
As you can see, debian provides ready-to-use kernel images for most systems, even versatile ARM
I didn't see it when experimenting with qemu-system-arm.
So, my first uname -a looked like:
Linux debian-mips 2.6.26-1-4kc-malta #1 Sat Jan 10 21:18:48 UTC 2009 mips GNU/Linux
And now it looks this way:
Linux debian-mips 2.6.36-rc6-4kc-malta #1 Wed Oct 6 07:41:36 UTC 2010 mips GNU/Linux
Not most recent, though prettier than one from 2009
As usual, I set up gcc and built nginx. Comparing with ARM in qemu (256M) the results for building nginx 0.8.53 with the following configure line:
are:
for mips 2.6.36-rc6, gcc 4.3.2, debian
and
for arm, 2.6.34.7, gcc 4.4.3, gentoo
I don't really know what I'm doing... I mean why, I guess I'm just a bit crazy so always looking for something new to me in order to try that and share some successful results
Guess I'll append real P1-200 mhz results for building nginx here a bit later
