Linux kernel patch for ACPI HMAT support

~ hucktech ~ Leave a comment

Ross Zwisler of Intel posted a new patch to the Linux kernel, with support for the ACPI 6.2 HMAT (Heterogeneous Memory Attribute Table).

This series adds kernel support for the Heterogeneous Memory Attribute Table (HMAT) table, newly defined in ACPI 6.2. The HMAT table, in concert with the existing System Resource Affinity Table (SRAT), provides users with information about memory initiators and memory targets in the system. A “memory initiator” in this case is any device such as a CPU or a separate memory I/O device that can initiate a memory request. A “memory target” is a CPU-accessible physical address range. The HMAT provides performance information (expected latency and bandwidth, etc.) for various (initiator,target) pairs. This is mostly motivated by the need to optimally use performance-differentiated DRAM, but it also allows us to describe the performance characteristics of persistent memory. The purpose of this RFC is to gather feedback on the different options for enabling the HMAT in the kernel and in userspace.

Intel-SGX-SSL

~ hucktech ~ Leave a comment

The Intel Software Guard Extensions SSL (Intel SGX SSL) cryptographic library is intended to provide cryptographic services for Intel Software Guard Extensions (SGX) enclave applications. The Intel SGX SSL cryptographic library is based on the underlying OpenSSL Open Source project, providing a full-strength general purpose cryptography library. The API exposed by the Intel SGX SSL library is fully compliant with unmodified OpenSSL APIs.

Microsoft WinHEC Taipei 2017

~ hucktech ~ Leave a comment

Welcome to WinHEC June 2017 Registration
The Windows Hardware Engineering Community (WinHEC) is where technical experts from around the world, and Microsoft, come together to make Windows great for every customer. Our next WinHEC event is June 14th and 15th in Taipei, Taiwan. The workshop will feature sessions and a lab for developers, product managers and planners to help prepare for Windows 10 S and to showcase the benefits of adopting key hardware features. Presentations will include: Introduction to Universal Drivers, Universal Developer Center for Hardware and Driver Servicing, Driver Flighting end-to-end, Windows Ink, Windows 10 Mixed Reality, Designing and Optimizing for Long Battery Life and Responsive Windows Devices, Windows Hello, and Developer Platform Updates. We will also have a guided, hands-on lab to explore and practice the concepts covered in the Introduction to Universal Driver session.

DMTF updates Redfish

New Redfish Update Adds Composability Support

Continuing its aggressive development timeline, an important update to the DMTF’s Redfish® standard is now available. The newly-released version 2017.1 of the Redfish Schema and version 1.2.0 of the Redfish Specification contain a number of additions, including support for composable infrastructures. With the ultimate goal of addressing all of the components in the data center with a consistent API, Redfish is an open industry standard that helps enable simple, modern and secure management of scalable platform hardware. DMTF continues to expand Redfish to cover customer use cases and technology, and the new Composition Service provides support for binding resources together into logical constructs. For example, disaggregated hardware – which allows for independent components, such as processors, memory, I/O controllers, and drives, to be bound together to create a composed Computer System – becomes a Computer System from an end user perspective in Redfish. Redfish composability allows clients to adjust their hardware configurations in response to their application needs, without having to touch any hardware.

Troll: ARM Cortex-M source-level debugger

~ hucktech ~ Leave a comment

The troll is a C-language source-level debugger for ARM Cortex-M systems, accessed with the excellent blackmagic hardware debug probe, and a customized variant of the blackmagic – the vx/blackstrike (or blackstrike for short). The troll only supports source-level debugging of source code programs written in the C programming language, compiled to executable files in the ELF format, containig DWARF debug information.[…]
