* [settings] Expose SMBIOS settings as global variablesMichael Brown2015-12-231-1/+1
| | | | Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [legal] Relicense files under GPL2_OR_LATER_OR_UBDLMichael Brown2015-03-021-1/+5
| | | | | | | | | | These files cannot be automatically relicensed by util/relicense.pl since they either contain unusual but trivial contributions (such as the addition of __nonnull function attributes), or contain lines dating back to the initial git revision (and so require manual knowledge of the code's origin).

* [smbios] Expose board serial number as ${board-serial}Dale Hamel2014-06-121-0/+12
| | | | | | | | With blade servers, the chassis serial number (exposed via ${serial}) may not be unique. Expose ${board-serial} as a named setting to provide easy access to a more meaningful serial number. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [settings] Explicitly separate the concept of a completed fetched settingMichael Brown2013-12-051-4/+4
| | | | | | | | | | The fetch_setting() family of functions may currently modify the definition of the specified setting (e.g. to add missing type information). Clean up this interface by requiring callers to provide an explicit buffer to contain the completed definition of the fetched setting, if required. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [settings] Clarify usage of the term "named setting"Michael Brown2013-07-181-2/+2
| | | | | | | | | | | | There are currently two conflicting usages of the term "named setting" within iPXE: one refers to predefined settings (such as show up in the "config" UI), the other refers to settings identified by a name (such as "net0.dhcp/ip"). Split these usages into the term "predefined setting" and "named setting" to avoid ambiguity. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [smbios] Allow access to multiple instances of SMBIOS structuresMichael Brown2013-05-012-4/+9
| | | | | | | | | | | | | | | | | | | | | | | Extend the syntax for numerical SMBIOS settings from smbios/<type>.<offset>.<length> to smbios/[<instance>.]<type>.<offset>.<length> Where SMBIOS provides multiple structures with the same <type>, this extended syntax allows for access to structures other than the first. If <instance> is omitted then it will default to zero, giving access to the first instance (and so matching existing behaviour). The 16-bit SMBIOS handle (which is an alternative way to disambiguate multiple instances of the same type of structure) can be accessed, if required, using smbios/<instance>.<type>.2.2:uint16 Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [smbios] Allow access to unreferenced SMBIOS stringsMichael Brown2013-05-011-4/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | iPXE allows access to general SMBIOS settings using the syntax: smbios/<type>.<offset>.<length> This provides access to any fixed-offset field within an SMBIOS structure. This syntax is currently overloaded to interpret a zero <length> as meaning that the byte at <offset> contains a string index; this provides access to SMBIOS strings (which are not located at fixed offsets). The "OEM Strings" SMBIOS structure contains strings which are not referenced by any fixed string index field within the structure. iPXE currently provides no way to access these strings. Fix by overloading the syntax for numerical SMBIOS settings to interpret an <offset> of zero as implying that <length> contains a literal string index. The OEM Strings can then be accessed using: smbios/11.0.1 smbios/11.0.2 smbios/11.0.3 ... The actual byte at offset zero will always contain the structure type, which is already known since it must be specified in order to access the structure. There is thus no plausible existing use case for an offset of zero; overloading the syntax in this way should therefore not break compatibility with any existing scripts. The corner case where both <offset> and <length> are zero is undefined (and, for now, will simply return a "not found" error). Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [settings] Eliminate settings "tag magic"Michael Brown2013-05-011-21/+11Star
| | | | | | | Create an explicit concept of "settings scope" and eliminate the magic values used for numerical setting tags. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [smbios] Mangle UUIDs for SMBIOS version 2.6 and newerMichael Brown2013-03-201-9/+33
| | | | | | | | | | | | | | | | iPXE treats UUIDs as being in network byte order (big-endian). The SMBIOS specification version 2.6 states that UUIDs are stored with little-endian values in the first three fields; earlier versions did not specify an endianness. This results in some inconsistency between the BIOS, vendor PXE, iPXE, and operating system interpretations of the SMBIOS UUID. dmidecode assumes that the byte order is little-endian if and only if the SMBIOS version is 2.6 or higher. Choose to match this behaviour. Reported-by: Matthew Helton <mwhelton@gmail.com> Reported-by: Alexandru Bordei <alexandru.bordei@gmail.com> Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [settings] Impose a fixed order on settingsMichael Brown2011-03-231-2/+2
| | | | | | | Improve the appearance of the "config" user interface by ensuring that settings appear in some kind of logical order. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [settings] Formalise notion of setting applicabilityMichael Brown2011-03-221-2/+18
| | | | | | | | | | | | | | | Expose a function setting_applies() to allow a caller to determine whether or not a particular setting is applicable to a particular settings block. Restrict DHCP-backed settings blocks to accepting only DHCP-based settings. Restrict network device settings blocks to accepting only DHCP-based settings and network device-specific settings such as "mac".

* [settings] Apply settings block name in register_settings()Michael Brown2010-12-011-2/+2
| | | | | | | | Pass the settings block name as a parameter to register_settings(), rather than defining it with settings_init() (and then possibly changing it by directly manipulating settings->name). Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [build] Rename gPXE to iPXEMichael Brown2010-04-202-6/+6
| | | | | | | | | | | Access to the gpxe.org and etherboot.org domains and associated resources has been revoked by the registrant of the domain. Work around this problem by renaming project from gPXE to iPXE, and updating URLs to match. Also update README, LOG and COPYRIGHTS to remove obsolete information.

* [settings] Allow for arbitrarily-named settingsMichael Brown2009-05-261-17/+0Star
| | | | | This provides a mechanism for using arbitrarily-named variables within gPXE, using the existing syntax for settings.
* [legal] Add a selection of FILE_LICENCE declarationsMichael Brown2009-05-182-0/+4
| | | | | Add FILE_LICENCE declarations to almost all files that make up the various standard builds of gPXE.
* [smbios] Add asset tag settingTimothy Stack2009-04-151-0/+8

* [efi] Use EFI-native mechanism for accessing SMBIOS tableMichael Brown2008-12-052-0/+379
EFI provides a copy of the SMBIOS table accessible via the EFI system table, which we should use instead of manually scanning through the F000:0000 segment.
