| * When attempting to migrate from a host with an older kernel to a host |
| * with a newer kernel we allow the newer kernel on the destination to |
| * list new registers with get-reg-list. We assume they'll be unused, at |
| * least until the guest reboots, and so they're relatively harmless. |
| * However, if the destination host with the newer kernel is missing |
| * registers which the source host with the older kernel has, then that's |
| * a regression in get-reg-list. This test checks for that regression by |
| * checking the current list against a blessed list. We should never have |
| * missing registers, but if new ones appear then they can probably be |
| * added to the blessed list. A completely new blessed list can be created |
| * by running the test with the --list command line argument. |
| * |
| * Note, the blessed list should be created from the oldest possible |
| * kernel. We can't go older than v4.15, though, because that's the first |
| * release to expose the ID system registers in KVM_GET_REG_LIST, see |
| * commit 93390c0a1b20 ("arm64: KVM: Hide unsupported AArch64 CPU features |
| * from guests"). Also, one must use the --core-reg-fixup command line |
| * option when running on an older kernel that doesn't include df205b5c6328 |
