Arm and Linaro are jointly developing “Energy Aware Scheduling”, a technique that improves power management on Linux by making it more central and easier to tune. Since the original discussions started on the Linux Kernel Mailing List back in 2013, there has been significant progress during 2015 with the posting of a full-functionality implementation. This talk will cover details of the components and how to get involved.
SFO15 302 Energy Aware Scheduling: Progress Update
BKK19-111 - DRM HW Composer for Beagle X15 BoardTuesday, April 16, 2019
Describing the process of adaptation AOSP DRM HWC to be used on Beagle X15 Board (4.14 kernel).
This can be used as an example of launching the external/drm_hwc on a board: a simple "How to" with the minimun steps required to get the drm_hwc functional.
SAN19-413 - TEE based Trusted Keys in LinuxFriday, October 4, 2019
Protecting key confidentiality is essential for many kernel security use-cases such as disk encryption, file encryption and protecting the integrity of file metadata. Trusted and encrypted keys provides a mechanism to export keys to user-space for storage as an encrypted blob and for the user-space to later reload them onto Linux keyring without the user-space knowing the encryption key. The existing Trusted Keys implementation relied on a TPM device but what if you are working on a system without one?
This session will introduce a Trusted Keys implementation which relies on a much simpler trusted application running in a Trusted Execution Environment (TEE) for sealing and unsealing of Trusted Keys using a hardware unique key provided by the TEE.
