[Qemu-devel] ethlite mac on virtex board
Hi Edgar,
I have a problem with Ethernet Lite on Virtex board as following.
Could you help me?
Thank you!

[Qemu-devel] PCI with Xilinx virtex-ml507 board
Hi, It seems that virtex board doesn't have a PCI bus emulation. I have tried to create one using ppc4xx_pci_init() function but it doesn't work. Could you help me some ideas to create PCI bus for virtex board? Or if you have already implemented PCI for virtex (I think that PCI is necessary to init Ethernet), could you send me the patch? Thank you very much, Tai

Thank for your answer. Beside nbench, I'm also using Dhrystone to measure the guest cpu performance. The performance does not much diffetence too. Is the emulated guest performance not depend on guest processor clock?

In this case, emulated guest processor clock has very little meaning IMO. After all, AFAIK it's just a complimentary info so it is seen as "real processor". -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com

Hi, I have a question about performance of Qemu for powerpc. When I'm changing the CPU clock for taihu board from 33Mhz to 330Mhz by setting the PLL value, the performance of Guest OS is not increased. I use nbench to measure the guest performance. Is qemu always running as maximum performance? Thank. Tai

Hi, It's not so much about what you can do with the virtex (I bet you can do lot's of stuff with it) but more limited to the devices available on the reference design. Take a look at: arch/powerpc/boot/dts/virtex440-ml507.dts to see what the reference design provides. QEMU provides only a subset of those devices. But you are of course free to create your own board or qemu machine, with what ever devices you'd like to throw in. Cheers

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 g3beigeHeathrow 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. Tai
[Qemu-devel] QEMU for ppc440 on i386 host
Hi! 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 0xc000 NIP c000 LR CTR XER MSR HID0 0300 HF idx 0 Segmentation fault $ qemu-system-ppc -M bamboo -kernel arch/powerpc/boot/uImage Trying to read privileged spr 947 3b3 at 1014 Trying to read invalid spr 62 03e at 0778 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!
