Session ID: SFO17-410 Session Name: KVM/ARM Nested Virtualization Support and Performance - SFO17-410 Speaker: Jintack Lim Track: Virtualization ★ Session Summary ★ Nested virtualization is increasingly important because of the need to deploy virtual machines running software stacks on top of virtualized cloud infrastructure, as well as for prototyping and testing. ARM recently introduced nested virtualization support in the latest ARMv8.3 revision of the architecture. We will present the efforts and challenges to introduce ARM nested virtualization support to KVM/ARM, which involves adding significant logic to core KVM/ARM code, MMU support, timers, and the GIC emulation including the changes we made since the last Linaro Connect. We will also discuss a paravirtualization approach we have used to prototype and evaluate the implementation on current ARMv8 hardware without hardware support for nested virtualization. We will present performance results and discuss future techniques to improve performance. --------------------------------------------------- ★ Resources ★ Event Page: http://connect.linaro.org/resource/sfo17/sfo17-410/ Presentation: Video: https://www.youtube.com/watch?v=lvxu8tMztbA --------------------------------------------------- ★ Event Details ★ Linaro Connect San Francisco 2017 (SFO17) 25-29 September 2017 Hyatt Regency San Francisco Airport --------------------------------------------------- Keyword: 'http://www.linaro.org' 'http://connect.linaro.org' --------------------------------------------------- Follow us on Social Media https://www.facebook.com/LinaroOrg https://twitter.com/linaroorg https://www.youtube.com/user/linaroorg?sub_confirmation=1 https://www.linkedin.com/company/1026961

★ Session Summary ★
Kubernetes and DPDK are the biggest hype for NFV solution today. While container provides high scale, low latency and low startup time, and it changes the virtualization model. Also, Kubernetes is the best container orchestration platform, from the test result about containerized VNFs and the community feedback, although there still has some problems to solve. DPDK provides a fast data-path. It’s the necessary component for NFV.
This presentation will show our work of leveraging lightweight, efficient modern container technology to build ARM-based NFV infrastructure. It also describes the deployment of containerized VNFs with DPDK data plane acceleration with high performance and low latency networking design. The benefits of leveraging container-based infrastructure for NFV use cases, particularly on the network edge based on ARM servers will be illustrated.

Session Name: Optimizing the Design and Implementation of KVM/ARM - SFO17-403
Speaker: Christoffer Dall
Track: Virtualization
★ Session Summary ★
A key drawback in the use of full system virtualization is the performance penalty introduced by hypervisors. This problem is especially present on ARM, which has significantly higher overhead for some workloads compared to x86, due to differences in the hardware virtualization support. The key reason for the overhead on ARM is the need to multiplex kernel mode state between the hypervisor and VMs, which each run their own kernel. This talk will cover how we have redesigned and optimized KVM/ARM, resulting in an order of magnitude reduction in overhead, and resulted in less overhead than x86 on key hypervisor operations. Our optimizations rely on new hardware support in ARMv8.1, the Virtualization Host Extensions (VHE), but also support legacy hardware through invasive modifications to Linux to support running the kernel in the hypervisor-specific CPU mode, EL2

XPDDS18: Design Session - SGX deep dive and SGX Virtualization Discussion, Ka...The Linux Foundation
Software Guard Extensions (SGX) is Intel's unique security feature which has been present in Intel's processors since Skylake generation. Existing HW/SW solutions hypervisor does not protect tenants against the cloud provider and thus the supplied operating system and hardware. Intel SGX solves this by using enclave, which is a protected portion of userspace application where the code/data cannot be accessed directly from outside by any software, including privileged ones, such as BIOS and VMM. This discussion is intended for the deep dive introduction to SGX, and the design discussion of adding SGX virtualization to Xen. We will start with SGX deep dive, and then go into SGX virtualization design, from high level design to details, such as EPC management/virtualization, CPUID handling, interaction with VMX, live migration support, etc.LMG Lightning Talks - SFO17-205

Project ACRN EtherCAT 101
EtherCAT is a fieldbus technology that uses standard Ethernet to enable real-time industrial control. It works by having the EtherCAT master send frames that slaves process on the fly as they are forwarded, without involving upper communication layers. FSoE builds on EtherCAT to enable safety communication using a "black channel" approach where only safety endpoints comply with functional safety standards. It achieves safe states through collaboration of multiple safety nodes in a system rather than relying on a single node like the master.
LF_OVS_17_Enabling Hardware Offload of OVS Control & Data plane using LiquidIO
This document discusses enabling Open vSwitch (OVS) hardware offload using Cavium's LiquidIO smart network interface cards (NICs). It describes two models for offloading OVS - data plane offload which keeps the control plane on the host, and full offload which moves both control and data planes to the NIC. The LiquidIO model represents a full offload where OVS runs natively on the NIC's processor. Performance tests show LiquidIO OVS offload achieving higher throughput and lower CPU usage than software-based OVS. Integration with OpenStack is also discussed.

淺談 Live patching technology
Live patching technology allows updating the Linux kernel without downtime. Ksplice was an early live patching solution released in 2009 but was limited and had licensing issues. kGraft and Kpatch were later developed by SUSE and Red Hat respectively as open source live patching solutions. Both use object code comparison and replacement at runtime, but kGraft can patch without stopping processes while Kpatch uses stop_machine to ensure safe replacement. Live patching is useful for critical bugs but has limitations around data structure and common function changes.

LAS16-500: The Rise and Fall of Assembler and the VGIC from Hell
Speakers: Marc Zyngier, Christoffer Dall
Date: September 30, 2016
★ Session Description ★
KVM/ARM has grown up. While the initial implementation of virtualization support for ARM processors in Linux was a quality upstream software project, there were initial design decisions simply not suitable for a long-term maintained hypervisor code base. For example, the way KVM/ARM utilized the hardware support for virtualization, was by running a ‘switching’ layer of code in EL2, purely written in assembly. This was a reasonable design decision in the initial implementation, as the switching layer only had to do one thing: Switch between a VM and the host. But as we began to optimize the implementation, add support for ARMv8.1 and VHE, and added features such as debugging support, we had to move to a more integrated approach, writing the switching logic in C code as well. As another example, the support for virtual interrupts, famously known as the VGIC, was designed with a focus on optimizing MMIO operations. As it turns out, MMIO operations is a less important and infrequent operation on the GIC, and the design had some serious negative consequences for supporting other state transitions for virtual interrupts and had negative performance implications. Therefore, we completely redesigned the VGIC support, and implemented the whole thing from scratch as a team effort, with a very promising result, upstream since Linux v4.7. In this talk we will cover the evolution of this software project and give an overview of the state of the project as it is today.

Alessio Lama - Development and testing of a safety network protocol
This document discusses the development and testing of safety network protocols for applications in automotive, industrial automation, and other fields. It outlines several issues with network communication such as access denial, repetition, loss, corruption, and timeouts. It then describes techniques for addressing these issues, including the use of VLANs for access control, CRC and hash functions for error detection, supervision packets for connection monitoring, and timestamps for timeout detection. Finally, it discusses tools for testing protocols, such as Wireshark, Scapy, TTCN-3, PTP, and PRP, which provides redundancy against network failures.
OVS v OVS-DPDK
This document discusses Open vSwitch (OVS) and how using Data Plane Development Kit (DPDK) can improve its performance. It notes that with standard OVS, there are many components between a virtual machine and physical networking that cause scalability and performance issues due to context switches. OVS-DPDK addresses this by using polling, hugepages, pinned CPUs, and userspace I/O to bypass the kernel and reduce overhead. The document shows that using DPDK can increase OVS throughput by over 8x and reduce latency by 30-37% compared to standard OVS.
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.
LF_OVS_17_OVS-DPDK Installation and Gotchas
1) The document provides instructions for installing and configuring OVS DPDK on Ubuntu 17.04, including specifying hardware, installing prerequisites, configuring grub, identifying NIC ports, binding interfaces to DPDK drivers, setting up the OVS bridge and adding ports.
2) Key steps include reserving hugepages in grub, binding NICs to igb_uio or vfio-pci drivers, setting OVS configuration like datapath type and memory allocation, and adding interfaces to the OVS bridge.
3) The scripts provided automate many of these steps but additional manual configuration may still be needed and issues can occur with making interfaces persistent after reboots.
Building, deploying and testing an industrial linux platform @ Open source su...
To introduce a robust, secure and reliable platform for the industrial environments is a key challenge. Therefore, running with the industrial-grade Linux distribution to fulfill the requirements mentioned above is imperative. The Linux distribution includes the Linux kernel and user space. Based on this testing design, the distribution will be built, deployed and tested in the device under automatic test by using continuous integration development practice to withstand the harsh industrial environments. In this presentation, SZ Lin will introduce how the industrial-grade Linux distribution is built, deployed and tested without human intervention, and review the test scope in both Linux kernel and user space. In addition, he will also address the design architecture of 24/7 long-term automated testing in all device under test with each release of new update.
Project ACRN CPU sharing BVT scheduler in ACRN hypervisor
This document describes the Borrowed Virtual Time (BVT) scheduler algorithm implemented in the ACRN hypervisor. BVT aims to provide weighted fair sharing of CPU resources across VMs while prioritizing latency-sensitive workloads. It tracks an effective virtual time for each VM and dispatches the VM with the earliest time. Latency threads can "warp" back in time. BVT is evaluated against the IORR scheduler in ACRN across CPU throughput, I/O throughput and latency tests, showing BVT provides more fair sharing and higher performance. The BVT implementation consists of 302 lines of code in the acrn-hypervisor.
KubeCon EU 2016: Secure, Cloud-Native Networking with Project Calico
Why does the network matter and why does it need to be simple (the 3am test)? Why should we build networks that scale to the extremes and how can we do that with proven technologies? Finally, how can we secure microservices, why should we bother, and what does this mean for developers and operators?

BKK16-410 SoC Idling & CPU Cluster PM
The linux kernel has two distinct ways of managing idle. The CPUidle framework for CPUs and for all other devices: runtime PM combined with generic power domains (genpd). In addition, CPUidle is not scaling well for multi-cluster SMP systems and heterogeneous systems like big.LITTLE. To better manage idle for modern SoCs with a hierarchical structure, we are exploring extending runtime PM and genpd to CPUs so there is a unified framework for managing idle across all devices.

BKK16-305B ILP32 Performance on AArch64
ILP32 is a programming model that may be useful on AArch64 systems for performance and also for legacy code with 32-bit data size assumptions. We combined ILP32 support from upstream projects with the LEAP distribution to enable experimentation with this model. This talk discusses the relative benchmark performance of the LP64 and ILP32 programming models under AArch64.
Accelerating Neutron with Intel DPDK
Accelerating Neutron with Intel DPDK from #vBrownBag session at OpenStack Summit Atlanta 2014.
1. Many OpenStack deployments use Open vSwitch plugin for Neutron.
2. But its performance and scalability are not enough for production.
3. Intel DPDK vSwitch - an DPDK optimized version of Open vSwitch developed by Intel and publicly available at 01.org. But it doesn't have enough functionality for Neutron. We have implemented the needed parts included GRE and ARP stacks. Neutron pluging
4. We got 5 times performance improving for netwroking in OpenStack!
LF_OVS_17_LXC Linux Containers over Open vSwitch
This document discusses using LXC Linux containers over Open vSwitch (OVS) for container networking. It provides information on the Orabuntu-LXC project which builds and installs OVS and LXC to deploy containerized Oracle software. It describes how LXC 2.1.0 added explicit support for OVS and how OVS can be configured as a systemd service. It also discusses using OVS with containerized DNS/DHCP and sending container traffic over GRE tunnels.
Implementing SR-IOv failover for Windows guests during live migration
Presentation from KVM Forum 2020.
In the past, there were several attempted to enable live migration for VMs that are using SR-IOV NICs. We are going to discuss the recent development based on the SR-IOV failover feature in virtio specification and its implementation for the Windows guests. In this session, Annie Li and Yan Vugenfirer will provide an overview of the failover feature and discuss specifics of the Windows guest implementation.
RTOS application verified by VeriFast, and future plan
The document discusses VeriFast, a verification tool for C and Java programs. It provides examples of how VeriFast has been used to verify real-time operating system (RTOS) applications and find bugs in the Linux kernel by analyzing programs annotated with preconditions and postconditions. Details are given on how to use VeriFast by writing assertions as comments in code and how it can statically verify programs using a style of "static design by contract". An RTOS called ChibiOS/RT is described and an example is shown of verifying state using VeriFast on an application running on this RTOS on a STM32 microcontroller board.

淺談 Live patching technology
Live patching technology allows updating the Linux kernel without downtime. Ksplice was an early live patching solution released in 2009 but was limited and had licensing issues. kGraft and Kpatch were later developed by SUSE and Red Hat respectively as open source live patching solutions. Both use object code comparison and replacement at runtime, but kGraft can patch without stopping processes while Kpatch uses stop_machine to ensure safe replacement. Live patching is useful for critical bugs but has limitations around data structure and common function changes.

LAS16-500: The Rise and Fall of Assembler and the VGIC from Hell
Speakers: Marc Zyngier, Christoffer Dall
Date: September 30, 2016
★ Session Description ★
KVM/ARM has grown up. While the initial implementation of virtualization support for ARM processors in Linux was a quality upstream software project, there were initial design decisions simply not suitable for a long-term maintained hypervisor code base. For example, the way KVM/ARM utilized the hardware support for virtualization, was by running a ‘switching’ layer of code in EL2, purely written in assembly. This was a reasonable design decision in the initial implementation, as the switching layer only had to do one thing: Switch between a VM and the host. But as we began to optimize the implementation, add support for ARMv8.1 and VHE, and added features such as debugging support, we had to move to a more integrated approach, writing the switching logic in C code as well. As another example, the support for virtual interrupts, famously known as the VGIC, was designed with a focus on optimizing MMIO operations. As it turns out, MMIO operations is a less important and infrequent operation on the GIC, and the design had some serious negative consequences for supporting other state transitions for virtual interrupts and had negative performance implications. Therefore, we completely redesigned the VGIC support, and implemented the whole thing from scratch as a team effort, with a very promising result, upstream since Linux v4.7. In this talk we will cover the evolution of this software project and give an overview of the state of the project as it is today.

Alessio Lama - Development and testing of a safety network protocol
This document discusses the development and testing of safety network protocols for applications in automotive, industrial automation, and other fields. It outlines several issues with network communication such as access denial, repetition, loss, corruption, and timeouts. It then describes techniques for addressing these issues, including the use of VLANs for access control, CRC and hash functions for error detection, supervision packets for connection monitoring, and timestamps for timeout detection. Finally, it discusses tools for testing protocols, such as Wireshark, Scapy, TTCN-3, PTP, and PRP, which provides redundancy against network failures.
OVS v OVS-DPDK
This document discusses Open vSwitch (OVS) and how using Data Plane Development Kit (DPDK) can improve its performance. It notes that with standard OVS, there are many components between a virtual machine and physical networking that cause scalability and performance issues due to context switches. OVS-DPDK addresses this by using polling, hugepages, pinned CPUs, and userspace I/O to bypass the kernel and reduce overhead. The document shows that using DPDK can increase OVS throughput by over 8x and reduce latency by 30-37% compared to standard OVS.
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.
LF_OVS_17_OVS-DPDK Installation and Gotchas
1) The document provides instructions for installing and configuring OVS DPDK on Ubuntu 17.04, including specifying hardware, installing prerequisites, configuring grub, identifying NIC ports, binding interfaces to DPDK drivers, setting up the OVS bridge and adding ports.
2) Key steps include reserving hugepages in grub, binding NICs to igb_uio or vfio-pci drivers, setting OVS configuration like datapath type and memory allocation, and adding interfaces to the OVS bridge.
3) The scripts provided automate many of these steps but additional manual configuration may still be needed and issues can occur with making interfaces persistent after reboots.
Building, deploying and testing an industrial linux platform @ Open source su...
To introduce a robust, secure and reliable platform for the industrial environments is a key challenge. Therefore, running with the industrial-grade Linux distribution to fulfill the requirements mentioned above is imperative. The Linux distribution includes the Linux kernel and user space. Based on this testing design, the distribution will be built, deployed and tested in the device under automatic test by using continuous integration development practice to withstand the harsh industrial environments. In this presentation, SZ Lin will introduce how the industrial-grade Linux distribution is built, deployed and tested without human intervention, and review the test scope in both Linux kernel and user space. In addition, he will also address the design architecture of 24/7 long-term automated testing in all device under test with each release of new update.
Project ACRN CPU sharing BVT scheduler in ACRN hypervisor
This document describes the Borrowed Virtual Time (BVT) scheduler algorithm implemented in the ACRN hypervisor. BVT aims to provide weighted fair sharing of CPU resources across VMs while prioritizing latency-sensitive workloads. It tracks an effective virtual time for each VM and dispatches the VM with the earliest time. Latency threads can "warp" back in time. BVT is evaluated against the IORR scheduler in ACRN across CPU throughput, I/O throughput and latency tests, showing BVT provides more fair sharing and higher performance. The BVT implementation consists of 302 lines of code in the acrn-hypervisor.
KubeCon EU 2016: Secure, Cloud-Native Networking with Project Calico

BKK16-410 SoC Idling & CPU Cluster PM
The linux kernel has two distinct ways of managing idle. The CPUidle framework for CPUs and for all other devices: runtime PM combined with generic power domains (genpd). In addition, CPUidle is not scaling well for multi-cluster SMP systems and heterogeneous systems like big.LITTLE. To better manage idle for modern SoCs with a hierarchical structure, we are exploring extending runtime PM and genpd to CPUs so there is a unified framework for managing idle across all devices.

It provides examples of how VeriFast has been used to verify real-time operating system (RTOS) applications and find bugs in the Linux kernel by analyzing programs annotated with preconditions and postconditions. Details are given on how to use VeriFast by writing assertions as comments in code and how it can statically verify programs using a style of "static design by contract". An RTOS called ChibiOS/RT is described and an example is shown of verifying state using VeriFast on an application running on this RTOS on a STM32 microcontroller board.
SDN, Network Virtualization and the Software Defined Data Center – Brad Hedlund
IT organizations around the world are transforming data center operations and economics by virtualizing their networks. Much like server virtualization decoupled VMs from the underlying X86 server hardware transforming the operational model of compute, network virtualization decouples software-based virtual networks from the underlying network hardware to enable a new operational model for networking. Deployed non-disruptively on any existing network without change, network virtualization transforms the physical network into a pool of capacity that can be consumed and repurposed on demand.
You will learn how, today, companies like AT&T, NTT, eBay and Rackspace have transformed their operational model and reduced network provisioning time from days/weeks to seconds. You will learn how network virtualization, OpenStack cloud management and Chef automation can be leveraged together and examine the architectural decisions you should be considering now to prepare for this transformation

Deep Learning Neural Network Acceleration at the Edge - Andrea Gallo
Short
The growing amount of data captured by sensors and the real time constraints imply that not only big data analytics but also Machine Learning (ML) inference shall be executed at the edge. The multiple options for neural network acceleration in Arm-based platforms provide an unprecedented opportunity for new intelligent devices. It also raises the risk of fragmentation and duplication of efforts when multiple frameworks shall support multiple accelerators.
Andrea Gallo, Linaro VP of Segment Groups, will summarise the existing NN frameworks, accelerator solutions, and will describe the efforts underway in the Arm ecosystem.
Abstract
The dramatically growing amount of data captured by sensors and the ever more stringent requirements for latency and real time constraints are paving the way for edge computing, and this implies that not only big data analytics but also Machine Learning (ML) inference shall be executed at the edge. The multiple options for neural network acceleration in recent Arm-based platforms provides an unprecedented opportunity for new intelligent devices with ML inference. It also raises the risk of fragmentation and duplication of efforts when multiple frameworks shall support multiple accelerators.
Andrea Gallo, Linaro VP of Segment Groups, will summarise the existing NN frameworks, model description formats, accelerator solutions, low cost development boards and will describe the efforts underway to identify the best technologies to improve the consolidation and enable the competitive innovative advantage from all vendors.
Audience
The session will be useful for executives to engineers. Executives will gain a deeper understanding of the issues and opportunities. Engineers at NN acceleration IP design houses will take away ideas for how to collaborate in the open source community on their area of expertise, how to evaluate the performance and accelerate multiple NN frameworks without modifying them for each new IP, whether it be targeting edge computing gateways, smart devices or simple microcontrollers.
Benefits to the Ecosystem
The AI deep learning neural network ecosystem is starting just now and it has similar implications with open source as GPU and video accelerators had in the early days with user space drivers, binary blobs, proprietary APIs and all possible ways to protect their IPs. The session will outline a proposal for a collaborative ecosystem effort to create a common framework to manage multiple NN accelerators while at the same time avoiding to modify deep learning frameworks with multiple forks.

Bud17 113: distribution ci using qemu and open qa
“Delivering a well working distribution is hard. There are a lot of different hardware platforms that need to be verified and the software stack is in a big flux during development phases. In rolling releases, this gets even worse, as nothing ever stands still. The only sane answer to that problem are working Continuous Integration tests. The SUSE way to check whether any change breaks normal distribution behavior is OpenQA. Using OpenQA we can automatically run tests that hard working QA people did manually in the old days. That way we have fast enough turnaround times to find and reject breaking changes This session shows how OpenQA works, what pitfalls we had to make ARM work with OpenQA and what we’re doing to improve it for ARM specific use cases.”

HKG18-501 - EAS on Common Kernel 4.14 and getting (much) closer to mainline
Session ID: HKG18-501
Session Name: HKG18-501 - EAS on Common Kernel 4.14 and getting (much) closer to mainline
Speaker: Chris Redpath
Track: Mobile, Kernel
★ Session Summary ★
This session will introduce the changes to EAS planned for 4.14 kernel, and how Arm hopes that EAS will develop in future. EAS has already evolved from an Arm/Linaro joint project to involving a much wider community of SoC vendors, Google and interested device manufacturers. We will highlight the product-specific pieces remaining in the Android Common Kernel EAS implementation, and our plans to provide an upstreaming plan for each product feature. In particular, the new 'simplified energy model' is designed to provide mainline-friendliness and comparable performance using a simple DT expression of cpu power/performance.

HKG18-TR08 - Upstreaming SVE in QEMU
"Session ID: HKG18-TR08
Session Name: HKG18-TR08 - Upstreaming SVE in QEMU
Speaker: Alex Bennée,Richard Henderson
Track: Enterprise
★ Session Summary ★
ARM's Scalable Vector Extensions is an innovative solution to processing highly data parallel workloads. While several out-of-tree attempts at implementing SVE support for QEMU existed, we took a fundamentally different approach to solving key challenges and therefore pursued a from-scratch QEMU SVE implementation in Linaro. Our strategic choice was driven by several factors. First as an ""upstream first"" organisation we were focused on a solution that would be readily accepted by the upstream project. This entailed doing our development in the open on the project mailing lists where early feedback and community consensus can be reached.

HKG18-120 - Devicetree Schema Documentation and Validation
"Session ID: HKG18-120
Session Name: HKG18-120 - Structured Documentation and Validation for Device Tree
Speaker: Grant Likely
Track: Kernel
★ Session Summary ★
Devicetree has become the dominant hardware configuration language used when building embedded systems. Projects using Devicetree now include Linux, U-Boot, Android, FreeBSD, and Zephyr. However, it is notoriously difficult to write correct Devicetree data files. The dtc tools perform limited tests for valid data, and there there is not yet a way to add validity test for specific hardware descriptions. Neither is there a good way to document requirements for specific bindings. Work is underway to solve these problems. This session will present a proposal for adding Devicetree schema files to the Devicetree toolchain that can be used to both validate data and produce usable documentation.

Speaker: Tamas Ban
Track: LITE
★ Session Summary ★
An overview of the trusted boot concept and firmware update on the ARMv8-M based platform and how MCUBoot acts as a BL2 bootloader for TF-M.
Trusted Firmware M
In October 2017, Arm announced the vision of Platform Security Architecture (PSA) - a common framework to allow everyone in the IoT ecosystem to move forward with stronger, scalable security and greater confidence. There are three key stages to the Platform Security Architecture: Analysis, Architecture and Implementation which are described at https://developer.arm.com/products/architecture/platform-security-architecture.
_Trusted Firmware M, i.e. TF-M, is the Arm project to provide an open source reference implementation firmware that will conform to the PSA specification for M-Class devices. Early access to TF-M was released in December 2017 and it is being made public during Linaro Connect. The implementation should be considered a prototype until the PSA specifications reach release state and the code aligns._

HCL Notes and Domino License Cost Reduction in the World of DLAU
Webinar Recording: https://www.panagenda.com/webinars/hcl-notes-and-domino-license-cost-reduction-in-the-world-of-dlau/
The introduction of DLAU and the CCB & CCX licensing model caused quite a stir in the HCL community. As a Notes and Domino customer, you may have faced challenges with unexpected user counts and license costs. You probably have questions on how this new licensing approach works and how to benefit from it. Most importantly, you likely have budget constraints and want to save money where possible. Don’t worry, we can help with all of this!
We’ll show you how to fix common misconfigurations that cause higher-than-expected user counts, and how to identify accounts which you can deactivate to save money. There are also frequent patterns that can cause unnecessary cost, like using a person document instead of a mail-in for shared mailboxes. We’ll provide examples and solutions for those as well. And naturally we’ll explain the new licensing model.
Join HCL Ambassador Marc Thomas in this webinar with a special guest appearance from Franz Walder. It will give you the tools and know-how to stay on top of what is going on with Domino licensing. You will be able lower your cost through an optimized configuration and keep it low going forward.
These topics will be covered
- Reducing license cost by finding and fixing misconfigurations and superfluous accounts
- How do CCB and CCX licenses really work?
- Understanding the DLAU tool and how to best utilize it
- Tips for common problem areas, like team mailboxes, functional/test users, etc
- Practical examples and best practices to implement right away
