Hi all,

這是在介紹LCE 12 Copenhagen討論big.LITTLE架構的進度
詳細的pdf如下:

這是demo video:

ARM release的官方video,相信有些人已經看過了:

這是big.LITTLE的MP tree,我有大概喵了一下,可是沒有看到硬體實做的部分,不知道是不是architecture dependent的方面還沒有做進去,只有演算法先進:

Regards,

介紹的摘錄:
==================================================================

LCE 12 Copenhagen – What’s all the Fuss about?

This event will bring together over 250 participants from over 50 companies, ranging from kernel hackers to integration engineers to ARM SoC industry executives and more, who will gather for a week to present, discuss and develop features,  infrastructure and optimizations for the Linux kernel, Android, Ubuntu and beyond to help shape the future of Linux on ARM.

The week will kick off with short high-level plenary, followed by a few introductory sessions. Mornings are filled with presentations and discussion sessions on key topics which impact the Linux on ARM ecosystem, while the afternoons focus on hacking sessions. Think of it as learn in the mornings and apply the knowledge in the afternoon.

LCE 12 Copenhagen will also host three mini-summits – ARMv8 (64-bit) on the Tuesday, Android on Wednesday and a big.LITTLE on Thursday.

Regular track sessions will follow the plenaries in the mornings Monday through Friday. and those tracks align with Linaro’s working groups and include: Android, Graphics and multimedia, Kernel, Platform (Ubuntu and generic Linux), Power, QA/Infrastructure, Tools, Training, Validation/LAVA.

This is the place to meet the engineers and managers deciding where Linux on ARM is going, and also to make the world aware of your own development projects.

Hi all,

剛剛看到big.LITTLE硬體相關實做for Linux kernel。在 http://git.linaro.org/gitweb?p=people/nico/linux.git;a=summary
裏面的 bL_cluster_pm branch。


這裡面有所有LCE 12的投影片:
