Revert r330897:

This was intended to be a non-functional change. It wasn't. The commit message was thus wrong. In addition it broke arm, and merged crypto related code. Revert with prejudice. This revert skips files touched in r316370 since that commit was since MFCed. This revert also skips files that require $FreeBSD$ property changes. Thank you to those who helped me get out of this mess including but not limited to gonzo, kevans, rgrimes. Requested by: gjb (re)

Partial merge of the SPDX changes

These changes are incomplete but are making it difficult to determine what other changes can/should be merged. No objections from: pfg

MFC r303261,r315059:

2017-04-16T07:21:20Z

r303261: Add more UEFI/e820 memory types from latest specifications. r315059: Split overbloated machep.c to multiple files and do basic cleanup of these fragments.

- 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

2012-09-28T11:59:32Z

bits under #ifdef _KERNEL but leave definitions for various structures defined by standards ($PIR table, SMAP entries, etc.) available to userland. - Consolidate duplicate SMBIOS table structure definitions in ipmi(4) and smbios(4) in and make them available to userland. MFC after: 2 weeks

A simple rewrite of biossmap.c:

2009-04-15T17:31:22Z

- 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

- Add constants for the different memory types in the SMAP table.

2007-10-28T21:23:49Z

- Use the SMAP types and constants from in the boot code rather than duplicating it.

Make the facility for recognizing BIOS-signatures more general

and return a printable representation. This fixes recognition of the PC Engines WRAP and improves the recognition of the Soekris boards (Bios version can now be seen in the dmesg output for instance). Also, add watchdog support for PCM-582x platforms. Submitted by: Adrian Steinmann Slightly changed by: phk PR: 81360
