About Me

I'm the Technical Architect for Canonical's Commercial Engineering team. My background is in Linux kernel development, mostly for hardware enablement & bringup.

Contributions

I've been working on a few things:

• Hardware enablement on the x86, arm and powerpc architectures. This is mostly kernel development.

• Tracking the progress of ARMv8 - at present, this is mainly around toolchain support.

• Planning and development for OEM Ubuntu preinstall projects (eg, the Ubuntu BIOS/UEFI requirements document)

• Ubuntu support for UEFI and Secure Boot. Most recently, I've been working on key management infrastructure for secure boot.

• Initial design and development work for the ARM clock subsystem & device tree infrastructure

• I'm the kernel maintainer of the SPU filesystem. SPUFS provides userspace access to the vector offload processors on the Cell Broadband Engine.

• The patchwork web-based patch tracking system

• Various askubuntu contributions

Future Goals

Most of my plans for the quantal cycle are based around UEFI, to ensure we have the components to support Ubuntu on UEFI & secure-boot enabled hardware (both preinstalls and post-sale installs of Ubuntu), and associated management infrastructure.

There's a few components to this:

• Rolling out changes to the preinstall process that work with OEM factory setup for UEFI-based machines
• Developing tools for managing signing and verification of the Ubuntu boot process
• Ensuring that the Ubuntu boot infrastructure works with secure boot
• Implementation of key management infrastructure for post-install updates of secure boot configuration
• Hardware enablement for new features in UEFI

Jeremy work with Grant Likely on bringing device tree to the ARM architecture which is important for Ubuntu on ARM. I am working on Ubuntu kernel for Calxeda ARM Server SoC and its highly relied on device tree. Thanks, Jeremy. @ikepanhc@
