* [efi] Use the EFI_RNG_PROTOCOL as an entropy source if availableMichael Brown2015-04-141-3/+76
| | | | | | | | | | | | | | | Entropy gathering via timer ticks is slow under UEFI (of the order of 20-30 seconds on some machines). Use the EFI_RNG_PROTOCOL if available, to speed up the process of entropy gathering. Note that some implementations (including EDK2) will fail if we request fewer than 32 random bytes at a time, and that the RNG protocol provides no guarantees about the amount of entropy provided by a call to GetRNG(). We take the (hopefully pessimistic) view that a 32-byte block returned by GetRNG() will contain at least the 1.3 bits of entropy claimed by min_entropy_per_sample().

* [build] Rename gPXE to iPXEMichael Brown2010-04-201-3/+3
| | | | | | | | | | | Access to the gpxe.org and etherboot.org domains and associated resources has been revoked by the registrant of the domain.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.

* [legal] Add a selection of FILE_LICENCE declarationsMichael Brown2009-05-181-0/+2
| | | | | Add FILE_LICENCE declarations to almost all files that make up the various standard builds of gPXE.
* [x86_64] Add support for compilation as an x86_64 binaryMichael Brown2008-12-051-0/+46
Currently the only supported platform for x86_64 is EFI. Building an EFI64 gPXE requires a version of gcc that supports __attribute__((ms_abi)). This currently means a development build of gcc; the feature should be present when gcc 4.4 is released. In the meantime; you can grab a suitable gcc tree from git://git.etherboot.org/scm/people/mcb30/gcc/.git
