spdx: The BSD-2-Clause-FreeBSD identifier is obsolete, drop -FreeBSD

2023-05-12T16:44:03Z

The SPDX folks have obsoleted the BSD-2-Clause-FreeBSD identifier. Catch up to that fact and revert to their recommended match of BSD-2-Clause. Discussed with: pfg MFC After: 3 days Sponsored by: Netflix

sys/amd64: further adoption of SPDX licensing ID tags.

2017-11-27T15:03:07Z

Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts.

Add more UEFI/e820 memory types from latest specifications.

- Add a new structure type for the ACPI 3.0 SMAP entry that includes the

optional attributes field. - Add a 'machdep.smap' sysctl that exports the SMAP table of the running system as an array of the ACPI 3.0 structure. (On older systems, the attributes are given a value of zero.) Note that the sysctl only exports the SMAP table if it is available via the metadata passed from the loader to the kernel. If an SMAP is not available, an empty array is returned. - Add a format handler for the ACPI 3.0 SMAP structure to the sysctl(8) binary to format the SMAP structures in a readable format similar to the format found in boot messages.

xen: implement hook to fetch and parse e820 memory map

2014-03-11T10:23:03Z

e820 memory map is fetched using a hypercall under Xen PVH, so add a hook to init_ops in oder to diverge from bare metal and implement a Xen variant. Approved by: gibbs Sponsored by: Citrix Systems R&D x86/include/init.h: - Add a parse_memmap hook to init_ops, that will be called to fetch and parse the memory map. amd64/amd64/machdep.c: - Decouple the fetch and the parse of the memmap, so the parse function can be shared with Xen code. - Move code around in order to implement the parse_memmap hook. amd64/include/pc/bios.h: - Declare bios_add_smap_entries (implemented in machdep.c). x86/xen/pv.c: - Implement fetching of e820 memmap when running as a PVH guest by using the XENMEM_memory_map hypercall.

- Re-shuffle the headers to move all kernel-specific

- Do not iterate int 15h, function e820h twice. Instead, we use STAILQ to store each return buffer and copy all at once. - Export optional extended attributes defined in ACPI 3.0 as separate metadata. Currently, there are only two bits defined in the specification. For example, if the descriptor has extended attributes and it is not enabled, it has to be ignored by OS. We may implement it in the kernel later if it is necessary and proven correct in reality. - Check return buffer size strictly as suggested in ACPI 3.0. Reviewed by: jhb
