[Qemu-devel] eepro100 and qemu0.14: unknown word write

[Sébastien BRICE]

Hi everyone 

I have been using qemu-kvm with success the last two years and its really amazing.
I am new to this mailing list and i am requesting your assistance because i struggle to have my virtual card working with an 'exotic' virtual System

address@hidden:~/qemu-kvm-0.14.0$ kvm -net nic,model=i82557b /media/prologue.img


Whatever i try the guest system never initializes the Intel 100 Pro NIC Card as it is supposed to do

And thats almost working with eep100.c source and -net nic,model=i82557b option
But each time the qemu hangs with:

eepro100: feature is missing in this emulation: unknown word write

Something is not working properly and i suspect some tweaking to do, some code to change to get it working

The thing is i am no that good with programming and i would very thankful if someone could help me a bit 

the function that gives me issues is this one below
thx you for your advices
any help welcome ^^

static void eepro100_write2(EEPRO100State * s, uint32_t addr, uint16_t val)
{
    /* SCBStatus is readonly. */
    if (addr > SCBStatus && addr <= sizeof(s->mem) - sizeof(val)) {
        memcpy(&s->mem[addr], &val, sizeof(val));
    }

    TRACE(OTHER, logout("addr=%s val=0x%04x\n", regname(addr), val));

    switch (addr) {
    case SCBStatus:
        s->mem[SCBAck] = (val >> 8);
        eepro100_acknowledge(s);
        break;
    case SCBCmd:
        eepro100_write_command(s, val);

        eepro100_write1(s, SCBIntmask, val >> 8);
        break;
    case SCBeeprom:
        eepro100_write_eeprom(s->eeprom, val);
        break;
    default:
        logout("addr=%s val=0x%04x\n", regname(addr), val);

        missing("unknown word write");
    }
}
