Get ready to test your Intel x86 systems!
Megha Dey of Intel submitted an 8-part patch to LUV that enables it to build on x86.
LUV has been useful for 64-bit x64 systems, and now is getting useful for 32-bit x86 systems!
Including 32-bit versions of BITS and CHIPSEC!
Is this the first time that pre-compiled binaries of CHIPSEC for x86 systems have been available? Not sure. Anyway, if you build from source you can start now, otherwise, look for the LUV-live binary download site to start having 32- and 64-bit versions, hopefully
Excerpt from part 0 of the patch:
[PATCH 0/8] Build and run LUV on 32 bit platforms
Currently LUV can be built only for 64 bit target platforms. This patchset contains patches which make sure that LUV can be compiled and run on both 32 as well as 64 bit target platforms. This required reworking of the PE header checks, adding call wrappers used by the shim bootloader to store and restore context, making sure chainloader.c compiled for 32 bit systems, adding support to ensure correct direct directory structure for 32 bit case and removing bugs in chipsec so that it could build without any erros on 32 bit systems. Also, the bits recipe is updated to build the grub EFI image only for target builds.This patchset addresses the following issue:
https://github.com/01org/luv-yocto/issues/57
grub: chainloader: shim: rework PE header checks
grub: shim: Add call wrappers for 32 bit systems
grub: shim: compile chainloader.c for 32bit system
luv : Correct directory structure for 32 bit case
luv: Add the ARCH parameter to chipsec Makefile
luv: chipsec : compile for 32 bit systems
bits: only build grub EFI image for target builds
bits: grub: specify location of images and modules for mkimage
