* sys/amd64: further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-271-0/+2
| | | | | | | | | | | | | | | 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. Notes: svn path=/head/; revision=326257
* Add more UEFI/e820 memory types from latest specifications.Alexander Motin2016-07-241-0/+3

* - Add a new structure type for the ACPI 3.0 SMAP entry that includes theJohn Baldwin2014-08-291-0/+8
| | | | | | | | | | | | | | | | | | 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 mapRoger Pau Monné2014-03-111-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 <machine/pc/bios.h> headers to move all kernel-specificJohn Baldwin2012-09-281-10/+42
| | | | | | | | | | | | | | 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 <machine/pc/bios.h> and make them available to userland. MFC after: 2 weeks Notes: svn path=/head/; revision=241027
* A simple rewrite of biossmap.c:Jung-uk Kim2009-04-151-0/+4
| | | | | | | | | | | | | | | | - 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.

* - Add constants for the different memory types in the SMAP table.John Baldwin2007-10-281-2/+8
| | | | | | | | - Use the SMAP types and constants from <machine/pc/bios.h> in the boot code rather than duplicating it. Notes: svn path=/head/; revision=173118
* Make the facility for recognizing BIOS-signatures more generalPoul-Henning Kamp2005-07-211-1/+16
| | | | | | | | | | | | | | | | | 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 <ast@marabu.ch> Slightly changed by: phk PR: 81360 Notes: svn path=/head/; revision=148231

* The general conesnsus on irc was that pci bios for config registersWarner Losh2001-08-211-0/+1
| | | | | | | | | | | | and such was just a bad idea and one that users should be forced to enable if they want it. This patch introduces a hw.pci.enable_pcibios tunable for those people. This does not impact the pcibios interrupt routing at all. Approved by: peter, msmith Notes: svn path=/head/; revision=82035

* More updates to the ACPI code:Mike Smith2000-09-301-0/+13
| | | | | | | | | | | | | | | | | | - Move all register I/O into acpi_io.c - Move event handling into acpi_event.c - Reorganise headers into acpivar/acpireg/acpiio - Move find-RSDT and find-ACPI-owned-memory into acpi_machdep - Allocate all resources (except those detailed only by AML) as real resources. Add infrastructure that will make adding resource support to AML code easy. - Remove all ACPI #ifdefs in non-ACPI code - Removed unnecessary includes - Minor style and commenting fixes Reviewed by: iwasaki Notes: svn path=/head/; revision=66489

| | | | | | | | | | | | - Add support for using the PCI BIOS functions for configuration space accesses, and make this the default. - Make PNPBIOS the default (obsoletes the PNPBIOS config option). - Add two new boot-time tunables to disable each of the above. Notes: svn path=/head/; revision=59294
