Re: [Qemu-devel] Anyone got qemu-system-ppc{,64} to boot anything?

[Baojun Wang]

in hw/ppc440.c:

    env = cpu_ppc_init("440EP");
    if (!env && kvm_enabled()) {
        /* XXX Since qemu doesn't yet emulate 440, we just say it's a 405.
         * Since KVM doesn't use qemu's CPU emulation it seems to be working
         * OK. */
        env = cpu_ppc_init("405");
    }
    if (!env) {
        fprintf(stderr, "Unable to initialize CPU!\n");
        exit(1);
    }

also in hw/ppc.c:

I can find ppc40x_irq_init/e500_irq_init(used mpc8544ds), but there is
no ppcbooke_irq_init? It seems hw/ppc405_uc.c is emulation for DCRs,
PLB, DMA, GPIO, I2C.., but there is no hw/ppc44x_uc.c.

the qemu source I used is 0.10.5.

Also in ppc/translate_init.c, there lots of CONFIG_USER_ONLY, but I
many of them are DEBUG or CACHE related SPR emulation, and since qemu
doesn't emulate cache, I think it's OK.

  Thanks,
Wang
