/*
* x86 System Management BIOS prtdiag
*
* Most modern x86 systems support a System Management BIOS, which is a memory
* buffer filled in by the BIOS at boot time that describes the hardware. This
* data format is described by DMTF specification DSP0134 (see http://dmtf.org)
* This file implements a rudimentary prtdiag(1M) display using the SMBIOS.
* Access to the data is provided by libsmbios: see <sys/smbios.h> for info.
*
* NOTE: It is important to understand that x86 hardware varies extremely
* widely and that the DMTF SMBIOS specification leaves way too much latitude
* for implementors, and provides no standardized validation mechanism. As
* such, it is not uncommon to find out-of-spec SMBIOSes or fields that
* contain strange and possibly even incorrect information. As such, this
* file should not be extended to report every SMBIOS tidbit or structure in
* the spec unless we have good reason to believe it tends to be reliable.
*
* Similarly, the prtdiag(1M) utility itself should not be used to spit out
* every possible bit of x86 configuration data from every possible source;
* otherwise this code will become an unmaintainable and untestable disaster.
* Extensions to prtdiag should prefer to use more stable kernel mechanisms
* that actually discover the true hardware when such subsystems are available,
* and should generally limit themselves to commonly needed h/w data. As such,
* extensions to x86 prtdiag should focus on integration with the device tree.
*
* The prtdiag(1M) utility is for service personnel and system administrators:
* it is not your personal ACPI disassembler or CPUID decoder ring. The
* complete SMBIOS data is available from smbdump(1), and other specialized
* tools can be created to display the state of other x86 features, especially
* when that information is more for kernel developers than box administrators.
