LAS16-200: SCMI - System Management and Control Interface
Title: SCMI - System Management and Control Interface
Abstract: In this session we present a new standard proposal for system control and management. The industry, both in high end mobile and enterprise, is trending towards the use of power and system controllers. In most cases the controllers have very similar communication mechanisms between application processors and controllers. In addition, these controllers generally provide very similar functions, e.g. DVFS, power domain management, sensor management. This standard proposal provides an extensible, OS agnostic, and virtualizable interface to access these functions.

HKG18-110 - net_mdev: Fast path user space I/O
Session ID: HKG18-110
Session Name: HKG18-110 - net_mdev: Fast path user space I/O
Speaker: Ilias Apalodimas
Track: Networking
★ Session Summary ★
User space I/O offers significant speedup potential for data plane and other high-performance applications, but at the high cost of writing and maintaining separate device drivers. Building on the existing kernel mediated device framework originally introduced to support GPUs, net\_mdev extends this support to network I/O, requiring only minor changes to existing kernel drivers. Applications, in turn, need only provide ""mini drivers"" to handle the performance I/O paths in user space while leaving control operations in the kernel.

BKK16-400A LuvOS and ACPI Compliance Testing
ARM server hardware will be shipping in 2016. An incredible amount of work has been done to get this far -- defining and implementing industry standards used by servers, development and testing of SoCs, and all sorts of Linux kernel work. So, how do we make sure we meet all these industry standards?
To a great extent, we've relied on magical thinking so far. That works, but only for so long. LuvOS and FWTS were created in order to catch many of the problems users have found; in this presentation, we describe how we have started extending FWTS to check for standards compliance, specifically ACPI and the SBBR, and how we can use LuvOS to run FWTS and other test suites so that we can rely on hard data, and not just wishful thinking.
LAS16-507: LXC support in LAVA

LAS16-210: Hardware Assisted Tracing on ARM with CoreSight and OpenCSD
Speakers: Mathieu Poirier
Date: September 27, 2016
★ Session Description ★
The CoreSight framework available in the Linux kernel has recently been integrated with the standard Perf trace system, making HW assisted tracing on ARM systems accessible to developers working on a wide spectrum of products. This presentation will start by giving a brief overview of the CoreSight technology itself before presenting the current solution, from trace collection in kernel space to off system trace decoding. To help with the latter part the Open CoreSight Decoding Library (openCSD) is introduced. OpenCSD is an open source library assisting with the decoding of collected trace data. We will see how it is used with the existing perf tools to provide an end-to-end solution for CoreSight trace decoding. The presentation will conclude with trace acquisition and decoding scenarios, along with tips on how to interpret trace information rendered by the perf tools.

LAS16-405: OpenDataPlane: Software Defined Dataplane leader
Speakers: François-Frédéric Ozog
Date: September 29, 2016
★ Session Description ★
You may think OpenDataPlane and DPDK are somewhat equivalent. But they are not. OpenDataPlane is about Software Defined Dataplanes while DPDK is a Software Dataplane. A Software Defined Dataplane can control a hardware only Dataplane in a way that packets can go from input port to output port without reaching a CPU core. With Software Dataplanes , all packets have to reach a CPU core. As a result, one vendor could leverage a Software Defined Dataplane to build a 100Tbps network box while it is not possible with a Software Dataplane.

Ostech war story using mainline linux for an android tv bsp
Android TV is a relatively recent Google Initiative to use the Android Operating System for TV Set-top-boxes, reusing the Phone Operating System architecture.
In the last years, the Android Hardware Abstraction Libraries were adapted/rewritten to use the modern and recent Linux APIs like DRM/KMS, V4L2 for Video Decode, ... allowing Android to boot and work with mainline Linux.
During last year, Neil was involved into an upstream-first open Android TV BSP, aiming to fully support AOSP for TV running on a Low-Cost generally available ARM based System-on-Chip designed for TV application. Neil will overview the requirements and struggles in term of system support, upstreaming & Android tweaking to enable AOSP to boot on such device, including the whole trusted boot chain, to graphical Linux with multimedia features enabled.

Optimized Data Management with Cloudera 5.7: Understanding data value with Cl...
Across all industries, organizations are embracing the promise of Apache Hadoop to store and analyze data of all types, at larger volumes than ever before possible. But to tap into the true value of this data, organizations need to manage this data and its subsequent metadata to understand its context, see how it’s changing, and take actions on it.
Cloudera Navigator is the only integrated data management and governance for Hadoop and is designed to do exactly this. With Cloudera 5.7, we have further expanded the capabilities in Cloudera Navigator to make it even easier to understand your data and maintain metadata consistency as it moves through Hadoop.

Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.
