EFI updates in latest Yocto release

Elizabeth Flanagan of Intel’s Yocto Project has announced the release of Yocto 1.7.3. Yocto is the Intel-backed embedded Linux system based on OpenEmbedded. Intel’s LUV (Linux UEFI Validation) distro, as in LUV-live, is Yocto-based. There are 3 UEFI-related updates that I can see:

 * grub-efi: Add backslash lost from previous commit
 * grub-efi: Use the backport patch from grub
 * init-install-efi.sh: fix gummiboot entry installation

Hmm, isn’t Gummiboot dead, replaced by the SystemD boot loader? If so, why is it still actively-maintained in Yocto?

And what about tummiboot, an Intel TXT-based fork of Gummiboot, shouldn’t Intel make that active? I haven’t checked, I hope tboot is available under Yocto, for BIOS today, and UEFI someday soon.

(I’d swear I did a blog post on tummiboot, but WordPress’s search abilities suck, and I suck at tagging, can’t find the post at the moment.)

Linux Foundation: combining Yocto with Debian

The CE Workgroup of the Linux Foundation occasionally does bids for research or work for related projects. One of the projects they’re interested in is supporting meta-Debian, a Yocto project that integrates with Debian. Earlier this week Tim Bird, Architecture Group Chair, CE Workgroup of the Linux Foundation, announced their proposals, exerpted here to focus on the Debian/Yocto project:

The CE Workgroup of the Linux Foundation occasionally solicits contractors for projects they are considering.  The following projects is currently under consideration for funding this year, and the CE Workgroup would be interested in hearing from you if you would like to work on them (and be paid for it!) For a while now, CEWG has been studying the feasibility of combining the Yocto Project with Debian, to create a system for using the Debian distribution for embedded projects.  The first proposal above, intends to solicit (paid) contributions to extending CEWGs project to more hardware and to include more libraries in the target distribution. If you are interested and are willing to get paid to work on this (producing or enhancing open source software to benefit the entire embedded industry), then please contact Tim Bird.

For the full announcement, see posting by Tim Bird. I’ve excerpting Tim’s announcement to only mention the meta-Debian project: he also mentioned two other projects, see the full announcement for details on those.

IMO, it would be nice to have Intel contributing to Debian in this way, providing Yocto-based vendors with more opportunities to use Debian, and helping Debian with embedded BSP (and hopefully some QA).

A bit of background on meta-debian, and some related projects:

Linaro makes LUVos-live available for ARM64

LUVos (Linux UEFI Validation — aka luvOS or LUVos, is a Yocto-based Linux distro that helps diagnose UEFI firmware. LUV-live is a liveimage boot version of LUVos. LUV-live also includes other hardware/firmware tools, such as BITS, FWTS, and CHIPSEC.

Intel-based LUV was initially only targeting Intel platforms. But LUV is an open source project, with a healthy community of contributors.

Recently Linaro has been porting LUV to ARM64. Thanks, Linaro! This is great news for ARM64 Linux enterprise hardware. Once Linaro ports CHIPSEC to ARM, it’ll be a very good day for ARM64 firmware defensive security tools.

It would be nice to consider an ARM32 port, as well as ARM64. All devices need bootkit detection tools, not just enterprise-class systems. 🙂

[Someone please wake up AMD. Right now, AFAICT, their platform now has the worst defensive tools. They need a LUV-live with a CHIPSEC that works on ARM systems.]
