[SeaBIOS] virtio-blk ... block size 4096 is unsupported

[James Shimer]

Hi,

I've been doing some testing if KVM with 4K physical sector virtio disks and they work with KVM as a none boot disk.  We'd like to be able to boot a 4k physical sector disk in KVM, is there 4K support in any seabios newer/upcoming releases, or is there a way to configure for 4k sectors?

reference from master
src/hw/virtio-blk.c lin 142

if (vdrive->drive.blksize != DISK_SECTOR_SIZE) {
            dprintf(1, "virtio-blk %pP block size %d is unsupported\n",
                    pci, vdrive->drive.blksize);
            goto fail;
        }

Thanks,
Jim
