Subject: [PATCH] tpm_emulator: Avoid double initialization during migration
|
|
mainline inclusion commit a0bcec03761477371ff7c2e80dc07fff14222d92 category:
|

---------------------------------------------------------------
|
|
|
|
When resuming after a migration, the backend sends CMD_INIT to the
|
|
emulator from the startup callback, then it sends the migration state
|
|
from the vmstate to the emulator, then it sends CMD_INIT again. Skip the
|
|
first CMD_INIT during a migration to avoid initializing the TPM twice.
