Hi, This series has two parts:
- First we add the ability to QOM objects to produce data consumable by the fw_cfg device, - Then we add the tls-cipher-suites object, and let it implement the FW_CFG_DATA_GENERATOR interface. This is required by EDK2 'HTTPS Boot' feature [*] to tell the guest which TLS ciphers it can use. ** Unresolved item: ** - Should a generated fw_cfg entry use a specific global order? https://lists.gnu.org/archive/html/qemu-devel/2020-06/msg02309.html ^ Gerd can you help? Since v7: - addressed Laszlo review comments (changes describe in each patch). Since v6: - addressed Laszlo & Daniel review comments Since v5: - Complete rewrite after chatting with Daniel Berrangé Since v4: - Addressed Laszlo comments (see patch#1 description) Since v3: - Addressed Markus' comments (do not care about heap) Since v2: - Split of Since v1: - Addressed Michael and Laszlo comments. Please review, Phil.
