2 How to install and configure a QEMU mips64-linux installation.

7 This gives an apparently stable, but extremely slow, mips64-linux
8 install. It has the advantage that the idle loop works right and so
9 when the guest becomes idle, qemu uses only very little host cpu, so
10 you can leave the guest idling for long periods without bad
11 performance effects on the host.
13 More or less following
14 https://gmplib.org/~tege/qemu.html section 8 (for mips64)
16 Build qemu-2.2.1 with --target-list including mips64-softmmu
21 wget ftp://ftp.sunet.se/pub/Linux/distributions/debian/dists/wheezy/main/installer-mips/current/images/malta/netboot/vmlinux-3.2.0-4-4kc-malta
23 wget ftp://ftp.sunet.se/pub/Linux/distributions/debian/dists/wheezy/main/installer-mips/current/images/malta/netboot/initrd.gz
25 md5sum initrd.gz vmlinux-3.2.0-4-4kc-malta
26 71f05a4aaf24671fa72e903abd76a448 initrd.gz
27 307fc61d36cb370ea2b697d587af45a6 vmlinux-3.2.0-4-4kc-malta
29 # Note. 4G is easily enough to install debian and do a build of Valgrind.
30 # If you envisage needing more space, now is the time to choose a larger
33 /path/to/Qemu221/bin/qemu-img create disk4G.img 4G
35 /path/to/Qemu221/bin/qemu-system-mips64 \
36 -M malta -cpu 5Kc -m 256 -hda disk4G.img \
37 -net nic,macaddr=52:54:00:fa:ce:08 -net user,hostfwd=tcp::5555-:22 \
38 -kernel vmlinux-3.2.0-4-4kc-malta -initrd initrd.img-3.2.0-4-4kc-malta \
39 -append "root=/dev/sda1 console=ttyS0 --" -nographic
41 Do an install, be as vanilla as possible, allow it to create a user
42 "username", and do not ask it to install any extra software. But,
45 ┌───────────────────┤ [!!] Finish the installation ├────────────────────┐
47 ┌│ Installation complete │
48 ││ Installation is complete, so it is time to boot into your new system. │
49 ││ Make sure to remove the installation media (CD-ROM, floppies), so │
50 ││ that you boot into the new system rather than restarting the │

55 └───────────────────────────────────────────────────────────────────────┘
58 then in the next menu "Execute a shell", "Continue"
60 This gives you a root shell in the new VM. In that shell:
62 mount -t proc proc /target/proc
63 mount --rbind /sys /target/sys
64 mount --rbind /dev /target/dev
68 System.map-3.2.0-4-5kc-malta initrd.img-3.2.0-4-5kc-malta
69 config-3.2.0-4-5kc-malta vmlinux-3.2.0-4-5kc-malta
71 Then on the host, copy out the vmlinux and initrd:
73 ssh -p 5555 username@localhost \
74 "tar -c -f - --exclude=lost+found /boot" | tar xf -
78 Select "Finish the installation"
81 When it reboots, kill qemu from another shell, else it will try to reinstall.
83 Now start the installation:
85 /path/to/Qemu221/bin/qemu-system-mips64 \
86 -M malta -cpu 5Kc -m 256 -hda disk4G.img -net nic,macaddr=52:54:00:fa:ce:08 \
87 -net user,hostfwd=tcp::5555-:22 -kernel boot/vmlinux-3.2.0-4-5kc-malta \
88 -initrd boot/initrd.img-3.2.0-4-5kc-malta \
89 -append "root=/dev/sda1 console=ttyS0" -nographic
91 System seems to have 256MB memory no matter how much you request.
93 This is basically a 32 bit system at this point. To get something
94 that can build 64 bit executables, it is necessary to install
95 gcc-multilib and g++-multilib.
97 Now you can ssh into the VM and install stuff as usual:
99 ssh -XC -p 5555 username@localhost
104 apt-get install make g++ gcc git emacs gdb automake autoconf
105 apt-get gcc-multilib g++-multilib
107 Configuring V on the guest:
110 CFLAGS="-mips64 -mabi=64" CXXFLAGS="-mips64 -mabi=64" \
111 ./configure --prefix=`pwd`/Inst
