18 | * Emulate a virtual board which works by passing Linux all the information | |
19 | * it needs about what devices are present via the device tree. | |
20 | * There are some restrictions about what we can do here: | |
21 | * + we can only present devices whose Linux drivers will work based | |
22 | * purely on the device tree with no platform data at all | |
23 | * + we want to present a very stripped-down minimalist platform, | |
24 | * both because this reduces the security attack surface from the guest | |
25 | * and also because it reduces our exposure to being broken when | |
26 | * the kernel updates its device tree bindings and requires further | |
27 | * information in a device binding that we aren't providing. | |
28 | * This is essentially the same approach kvmtool uses. | |

1040 | * create a list of virtio-mmio buses with decreasing base addresses. | |
1041 | * | |
1042 | * When a -device option is processed from the command line, | |
1043 | * qbus_find_recursive() picks the next free virtio-mmio bus in forwards | |
1044 | * order. The upshot is that -device options in increasing command line | |
1045 | * order are mapped to virtio-mmio buses with decreasing base addresses. | |
1046 | * | |
1047 | * When this code was originally written, that arrangement ensured that the | |
1048 | * guest Linux kernel would give the lowest "name" (/dev/vda, eth0, etc) to | |
1049 | * the first -device on the command line. (The end-to-end order is a | |
1050 | * function of this loop, qbus_realize(), qbus_find_recursive(), and the | |
1051 | * guest kernel's name-to-address assignment strategy.) | |
1052 | * | |
1053 | * Meanwhile, the kernel's traversal seems to have been reversed; see eg. | |
1054 | * the message, if not necessarily the code, of commit 70161ff336. | |
1055 | * Therefore the loop now establishes the inverse of the original intent. | |
1056 | * | |
1057 | * Unfortunately, we can't counteract the kernel change by reversing the | |
1058 | * loop; it would break existing command lines. | |
1059 | * | |
1060 | * In any case, the kernel makes no guarantee about the stability of | |
1061 | * enumeration order of virtio devices (as demonstrated by it changing | |
1062 | * between kernel versions). For reliable and stable identification | |
1063 | * of disks users must use UUIDs or similar mechanisms. | |
