What is LRA
●
A replacement of reload
●
What is reload ?
– Checks that each insn after register allocation is valid (operands are
in the right register class) and fixes them up
– Mostly machine-dependent and tries to do everything at once
– More than 25 years old and more than 20 000 LoC
– A blocker to new optimization
●
LRA
– New design of reload
– Divides this process in small and separated subtasks
– Iterative

Plans
●
GCC
– LTO and PGO
– libtsan (thread sanitizer)
– memory models
– Bug fixing

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. --------------------------------------------------- ★ Resources ★ Event Page: http://connect.linaro.org/resource/hkg18/hkg18-tr08/ Presentation: http://connect.linaro.org.s3.amazonaws.com/hkg18/presentations/hkg18-tr08.pdf Video: http://connect.linaro.org.s3.amazonaws.com/hkg18/videos/hkg18-tr08.mp4 --------------------------------------------------- ★ Event Details ★ Linaro Connect Hong Kong 2018 (HKG18) 19-23 March 2018 Regal Airport Hotel Hong Kong --------------------------------------------------- Keyword: Enterprise 'http://www.linaro.org' 'http://connect.linaro.org' --------------------------------------------------- Follow us on Social Media https://www.facebook.com/LinaroOrg https://www.youtube.com/user/linaroorg?sub_confirmation=1 https://www.linkedin.com/company/1026961"

"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. --------------------------------------------------- ★ Resources ★ Event Page: http://connect.linaro.org/resource/hkg18/hkg18-120/ Presentation: http://connect.linaro.org.s3.amazonaws.com/hkg18/presentations/hkg18-120.pdf Video: http://connect.linaro.org.s3.amazonaws.com/hkg18/videos/hkg18-120.mp4 --------------------------------------------------- ★ Event Details ★ Linaro Connect Hong Kong 2018 (HKG18) 19-23 March 2018 Regal Airport Hotel Hong Kong --------------------------------------------------- Keyword: Kernel 'http://www.linaro.org' 'http://connect.linaro.org' --------------------------------------------------- Follow us on Social Media https://www.facebook.com/LinaroOrg https://www.youtube.com/user/linaroorg?sub_confirmation=1 https://www.linkedin.com/company/1026961"

While technology has advanced after the end of Dennard scaling more than 10 years ago, the advances have slowed down. Server performance increases have relied on increasing core counts and power budgets. At the same time, workloads have changed in the era of cloud computing. Scale out is becoming more important than scale up. Domain specific architectures have started to emerge to improve the energy efficiency of emerging workloads like deep learning This talk will provide a historical perspective and discuss emerging trends driving the development of modern servers processors. --------------------------------------------------- ★ Resources ★ Event Page: http://connect.linaro.org/resource/hkg18/hkg18-500k1/ Presentation: http://connect.linaro.org.s3.amazonaws.com/hkg18/presentations/hkg18-500k1.pdf Video: http://connect.linaro.org.s3.amazonaws.com/hkg18/videos/hkg18-500k1.mp4 --------------------------------------------------- ★ Event Details ★ Linaro Connect Hong Kong 2018 (HKG18) 19-23 March 2018 Regal Airport Hotel Hong Kong --------------------------------------------------- Keyword: Keynote 'http://www.linaro.org' 'http://connect.linaro.org' --------------------------------------------------- Follow us on Social Media https://www.facebook.com/LinaroOrg https://www.youtube.com/user/linaroorg?sub_confirmation=1 https://www.linkedin.com/company/1026961

Session ID: HKG18-301 Session Name: HKG18-301 - Dramatically Accelerate 96Board Software via an FPGA with Integrated Processors Speaker: Glenn Steiner Track: LITE ★ Session Summary ★ Key Takeaways: With the drive to increase integration, reduce system costs, accelerate performance, and enhance reliability, software developers are discovering the processor they would like to target is simply not fast enough. This session will help you the system architect or software developer understand how you can architect and develop software on an FPGA integrated processor, and accelerate software code via FPGA accelerators. Abstract: As a software developer, in order to meet system level performance requirements, you may have realized that your next software project will be targeting a processor inside of an FPGA. How will this impact your development process and what benefits might you gain with this tight integration of processor and FPGA? Starting from the basics of what FPGAs are (in terms of software programming), this session will provide a simple to understand primer of what modern FPGAs with embedded processors can do. We will wrap up with examples of how high level synthesis tools can move software to programmable logic hardware enabling dramatic software acceleration. --------------------------------------------------- ★ Resources ★ Event Page: http://connect.linaro.org/resource/hkg18/hkg18-301/ Presentation: http://connect.linaro.org.s3.amazonaws.com/hkg18/presentations/hkg18-301.pdf Video: http://connect.linaro.org.s3.amazonaws.com/hkg18/videos/hkg18-301.mp4 --------------------------------------------------- ★ Event Details ★ Linaro Connect Hong Kong 2018 (HKG18) 19-23 March 2018 Regal Airport Hotel Hong Kong --------------------------------------------------- Keyword: LITE 'http://www.linaro.org' 'http://connect.linaro.org' --------------------------------------------------- Follow us on Social Media https://www.facebook.com/LinaroOrg https://www.youtube.com/user/linaroorg?sub_confirmation=1 https://www.linkedin.com/company/1026961

Heather Hedden, Senior Consultant at Enterprise Knowledge, presented “The Role of Taxonomy and Ontology in Semantic Layers” at a webinar hosted by Progress Semaphore on April 16, 2024. Taxonomies at their core enable effective tagging and retrieval of content, and combined with ontologies they extend to the management and understanding of related data. There are even greater benefits of taxonomies and ontologies to enhance your enterprise information architecture when applying them to a semantic layer. A survey by DBP-Institute found that enterprises using a semantic layer see their business outcomes improve by four times, while reducing their data and analytics costs. Extending taxonomies to a semantic layer can be a game-changing solution, allowing you to connect information silos, alleviate knowledge gaps, and derive new insights. Hedden, who specializes in taxonomy design and implementation, presented how the value of taxonomies shouldn’t reside in silos but be integrated with ontologies into a semantic layer. Learn about: - The essence and purpose of taxonomies and ontologies in information and knowledge management; - Advantages of semantic layers leveraging organizational taxonomies; and - Components and approaches to creating a semantic layer, including the integration of taxonomies and ontologies
