The branch stable/13 has been updated by corvink: URL: https://cgit.FreeBSD.org/src/commit/?id=c8029c30a8729b8af133352df92d1c4a0d41353e commit c8029c30a8729b8af133352df92d1c4a0d41353e Author: Corvin Köhne <corvink@FreeBSD.org> AuthorDate: 2022-11-16 08:31:29 +0000 Commit: Corvin Köhne <corvink@FreeBSD.org> CommitDate: 2022-12-05 07:39:34 +0000 bhyve: add helper to append a basl table without a header The common style for build an ACPI table will be: 1. basl_table_create 2. basl_table_append_header 3. setup an ACPI_TABLE_* struct 4. basl_table_append_bytes (without header) Add a helper for the last step.
