X-Received-From: 2401:3900:2:1::2 Subject: [Qemu-devel] [PATCH] spapr: Add forgotten capability to migration stream X-BeenThere: qemu-devel@nongnu.org X-Mailman-Version: 2.1.21 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Cc: clg@kaod.org, David Gibson , qemu-devel@nongnu.org, groug@kaod.org Errors-To: qemu-devel-bounces+importer=patchew.org@nongnu.org Sender: "Qemu-devel" X-ZohoMail-DKIM: fail (Header signature does not verify) Content-Type: text/plain; charset="utf-8" spapr machine capabilities are supposed to be sent in the migration stream so that we can sanity check the source and destination have compatible configuration. Unfortunately, when we added the hpt-max-page-size capability, we forgot to add it to the migration state. This means that we can generate spurious warnings when both ends are configured for large pages, or potentially fail to warn if the source is configured for huge pages, but the destination is not.
