My name is Tai. Sorry for bother you! I have a question about QEMU for powerpc. Can QEMU emulate the ppc440 on a i386 host? I mean it is full-system emulation. Because when I'm trying to run linux ppc440 with qemu on my i386 PC I alway get the error like that: $ qemu-system-ppc -M bamboo -kernel vmlinux qemu: fatal: Trying to execute code outside RAM or ROM at 0xc0000000 NIP c0000000 LR 00000000 CTR 00000000 XER 00000000 MSR 00000000 HID0 00000300 HF 00000000 idx 0 Segmentation fault $ qemu-system-ppc -M bamboo -kernel arch/powerpc/boot/uImage Trying to read privileged spr 947 3b3 at 00001014 Trying to read invalid spr 62 03e at 00000778 I using QEMU that configured and built with device tree support (enable libfdt). QEMU version 0.14.1 The kernel image is built for bamboo using powerpc-440 toolchain. kernel-version 2.6.38.2 Thank you very much!

So far, the only board that is somewhat known to work is the virtex5 ml507 one with a 440x5 xilinx cpu. Please see http://wiki.qemu.org/ChangeLog/0.14#PPC for details. The bamboo board was added to enable KVM support for 440, it hasn't been used with the emulation target yet. What exactly are you trying to emulate?

I'm trying to emulate the ppc440 on a i386 host. My final target: Linux for PPC440 can run on Qemu and drop a shell prompt. When I try to run this command: $ qemu-system-ppc -M ? Supported machines are: virtex-ml507 Xilinx Virtex ML507 reference design mpc8544ds mpc8544ds bamboo bamboo (alias of bamboo-0.13) bamboo-0.13 bamboo bamboo-0.12 bamboo ref405ep ref405ep taihu taihu mac99 Mac99 based PowerMAC g3beige Heathrow based PowerMAC (default) prep PowerPC PREP platform I find two boards that have a PPC440 cpu: virtex-ml507 and bamboo. I have checked the bamboo board fist, then I get the result as above. Hower, the ml507 board seems not working too. I have built kernel image for Virtex ML507 using powerpc-440 toolchain. kernel-version: linux-2.6.39 config: 44x/virtex5_defconfig When I'm trying to run: $ qemu-system-ppc -M virtex-ml507 -kernel arch/powerpc/boot/simpleImage.virtex440-ml507.elf I get the following output: Unable to get size of device tree file 'ppc.dtb' Warning: vlan 0 with no nics Qemu just display a monitor console, it seems not to be loading the kernel. Could you help me some ideas? Could you help me the guide to emulate virtex-ml507 on i368 host? Thank you very much.

Hi, I've just uploaded a test image to the wiki's download pages. See http://wiki.qemu.org/Download. You'll need a recent qemu, built with libfdt support. I threw in the linux kernelconfig used to build the image. I used a rather old version (2.6.34) of the kernel provided by Xilinx at: git://git.xilinx.com/linux-2.6-xlnx.git commit: 91e2c43452914a789a4bebea7c199695bbf888f2 My guess is that you should be able to build a kernel directly from upstream, but I haven't tried. One thing to note is that qemu still lacks support for the ll-temac (ethernet nic) and the kernel hangs when probing for it. The workaround is to remove it from the device tree file (ppc.dtb). Already done in the archive with my test image, but good to know if you start rolling your own stuff. Regarding the ll-temac, we've got it running and plan to submit, I just need to get some time to clean it up etc.. sorry. Good luck ^ permalink raw reply [flat|nested] 5+ messages in thread

I've just downloaded the test image from QEMU site. Then I run the qemu-run.sh script, it boot succesful. I get a nice shell. # cat /proc/cpuinfo processor : 0 cpu : 440 in Virtex-5 FXT revision : 25.16 (pvr 7ff2 1910) bogomips : 800.00 timebase : 400000000 platform : Xilinx Virtex440 model : testing Memory : 256 MB Thank for your support one more. I will get the Xilinx kernel and try to build it. Tai [-- Attachment #2: Type: text/html, Size: 8784 bytes --] ^ permalink raw reply [flat|nested] 5+ messages in thread
