The branch main has been updated by corvink: URL: https://cgit.FreeBSD.org/src/commit/?id=0926566f6f9cc1dba0d7b5d7e0b45484dd901b20 commit 0926566f6f9cc1dba0d7b5d7e0b45484dd901b20 Author: Corvin Köhne <corvink@FreeBSD.org> AuthorDate: 2022-07-22 08:09:01 +0000 Commit: Corvin Köhne <corvink@FreeBSD.org> CommitDate: 2023-04-12 06:27:04 +0000 bhyve: allow building device specific ACPI tables Some ACPI devices require a device specific acpi table. E.g. a TPM2 device requires a TPM2 table. Use the acpi_device_emul struct to define such a device specific table. Reviewed by: markj MFC after: 1 week Sponsored by: Beckhoff Automation GmbH & Co.
