This test boots a Linux kernel on a smdkc210 board and verify the serial output is working. The cpio image used comes from the linux-build-test project: https://github.com/groeck/linux-build-test If ARM is a target being built, "make check-acceptance" will automatically include this test by the use of the "arch:arm" tags.

Currently offloads disabled by guest via the VIRTIO_NET_CTRL_GUEST_OFFLOADS_SET command are not preserved on VM migration. Instead all offloads reported by guest features (via VIRTIO_PCI_GUEST_FEATURES) get enabled. What happens is: first the VirtIONet::curr_guest_offloads gets restored and offloads are getting set correctly: #0 qemu_set_offload (nc=0x555556a11400, csum=1, tso4=0, tso6=0, ecn=0, ufo=0) at net/net.c:474 thesofproject#1 virtio_net_apply_guest_offloads (n=0x555557701ca0) at hw/net/virtio-net.c:720 thesofproject#2 virtio_net_post_load_device (opaque=0x555557701ca0, version_id=11) at hw/net/virtio-net.c:2334 thesofproject#3 vmstate_load_state (f=0x5555569dc010, vmsd=0x555556577c80 <vmstate_virtio_net_device>, opaque=0x555557701ca0, version_id=11) at migration/vmstate.c:168 thesofproject#4 virtio_load (vdev=0x555557701ca0, f=0x5555569dc010, version_id=11) at hw/virtio/virtio.c:2197 thesofproject#5 virtio_device_get (f=0x5555569dc010, opaque=0x555557701ca0, size=0, field=0x55555668cd00 <__compound_literal.5>) at hw/virtio/virtio.c:2036 thesofproject#6 vmstate_load_state (f=0x5555569dc010, vmsd=0x555556577ce0 <vmstate_virtio_net>, opaque=0x555557701ca0, version_id=11) at migration/vmstate.c:143 thesofproject#7 vmstate_load (f=0x5555569dc010, se=0x5555578189e0) at migration/savevm.c:829 thesofproject#8 qemu_loadvm_section_start_full (f=0x5555569dc010, mis=0x5555569eee20) at migration/savevm.c:2211 thesofproject#9 qemu_loadvm_state_main (f=0x5555569dc010, mis=0x5555569eee20) at migration/savevm.c:2395 thesofproject#10 qemu_loadvm_state (f=0x5555569dc010) at migration/savevm.c:2467 thesofproject#11 process_incoming_migration_co (opaque=0x0) at migration/migration.c:449 However later on the features are getting restored, and offloads get reset to everything supported by features: #0 qemu_set_offload (nc=0x555556a11400, csum=1, tso4=1, tso6=1, ecn=0, ufo=0) at net/net.c:474 thesofproject#1 virtio_net_apply_guest_offloads (n=0x555557701ca0) at hw/net/virtio-net.c:720 thesofproject#2 virtio_net_set_features (vdev=0x555557701ca0, features=5104441767) at hw/net/virtio-net.c:773 thesofproject#3 virtio_set_features_nocheck (vdev=0x555557701ca0, val=5104441767) at hw/virtio/virtio.c:2052 thesofproject#4 virtio_load (vdev=0x555557701ca0, f=0x5555569dc010, version_id=11) at hw/virtio/virtio.c:2220 thesofproject#5 virtio_device_get (f=0x5555569dc010, opaque=0x555557701ca0, size=0, field=0x55555668cd00 <__compound_literal.5>) at hw/virtio/virtio.c:2036 thesofproject#6 vmstate_load_state (f=0x5555569dc010, vmsd=0x555556577ce0 <vmstate_virtio_net>, opaque=0x555557701ca0, version_id=11) at migration/vmstate.c:143 thesofproject#7 vmstate_load (f=0x5555569dc010, se=0x5555578189e0) at migration/savevm.c:829 thesofproject#8 qemu_loadvm_section_start_full (f=0x5555569dc010, mis=0x5555569eee20) at migration/savevm.c:2211 thesofproject#9 qemu_loadvm_state_main (f=0x5555569dc010, mis=0x5555569eee20) at migration/savevm.c:2395 thesofproject#10 qemu_loadvm_state (f=0x5555569dc010) at migration/savevm.c:2467 thesofproject#11 process_incoming_migration_co (opaque=0x0) at migration/migration.c:449 Fix this by preserving the state in saved_guest_offloads field and pushing out offload initialization to the new post load hook.
