Intel releases LUV (Linux UEFI Validation) v2.1

Today Ricardo Neri of Intel announced the 2.1 release of LUV. In additon to updating Linux to v4.11, FWTS to V17.06.00, CHIPSEC to v1.3.1, BITS to v2079, and NDCTL v56, they also started doing nightly builds. Here are some of the other highlights of this release, from the announcement:

Gayatri Kammela won the prize of the most active contributor with many bug fixes and a new feature. She fixed our netboot image, which was missing the ramdisk(!). She added support for debugging and logging of BITS output via network. Likewise, she reworked the LUV configuration file to make more sense to both humans and computers by making clear when parameters are not used. She also investigated and fixed dependencies in systemd that caused delays in the execution of tests. Lastly, she fixed a couple of build-time bugs.

Naresh Bhat updated our Linux kernel recipe to retrieve the kernel configuration directly from the source tree rather than manually updating it. This helped us to remove those eyesore patches for updating our configuration that needed to be sent every time we bumped to a new kernel version. The overall result looks great and is closer to the intended use of the kernel and Yocto Projects’s scripts to merge multiple configuration fragments. I took this opportunity to sanitize the configuration for x86 to add missing configurations and reorganize them.

Sai Praneeth Prakhya added functionality to dump relevant and useful dumps as part of the testing results. Now LUV is capable of dumping the kernel’s boot log, the contents of the ACPI tables as well as the properties of the CPUs in the system. Very useful! Also, he helped us to bump to Linux v4.11. He also took burden of rebasing our implementation to detect firmware’s illegal memory access in this new version of Linux.

Matt Hart updated our GRUB configuration to automate boots across all CPU architectures by not waiting for human intervention to complete boots.

In addition to stuff mentioned in LUV announcement, LUV also did some updates to how LUV calls CHIPSEC, see these posts:

These days, LUV-live ships with BIOS MBR or UEFI GPT partition types, local or network boot types, and x86 or x64 architecture type, multiple choices for the image:
