Intel: AMD Weak On Battery-Powered Laptop Performance - But DPTF On Linux Still Sucks

Intel held a virtual event last week to basically plead their case that AMD Ryzen laptops are coming up short on battery-powered performance compared to their own offerings. It was all Windows focused, but at least given their emphasis now on battery performance gave me another opportunity to prod over the lackluster state of Intel DPTF support on Linux with it not being pleasant out-of-the-box and one of the few areas encumbered by blobs or lack of public documentation.

Intel C for Metal Compiler 1.0.20 Released

Within Intel's vast open-source software ecosystem and much of the attention being on oneAPI as their preferred programming model for developers these days and there being multiple different open-source Intel graphics compiler back-ends, one that is often forgotten about is the Intel C for Metal Compiler that on Friday saw a new release.

Intel Tidies Up CET While Waiting For It To Land In The Linux Kernel

Intel's SGX enclaves support patches for the Linux kernel have been through 40+ rounds of review at this point over the past many months as they try to get this security feature into the mainline Linux kernel. But SGX isn't the only Intel security feature that's been having a long process for mainlining: Control-flow Enforcement Technology (CET) is in a similar boat.

Linux Might Wipe Out The Notorious Intel Poulsbo/Moorestown 2D Acceleration

Longtime Linux users still likely cringe when hearing "Poulsbo" as Intel's first-generation Atom processors that featured "GMA 500" graphics that were based on Imagination Technologies PowerVR SGX IP. The Linux driver support was just awful and now as we prepare for 2021 the Intel Linux kernel driver might just drop its 2D acceleration support for Poulsbo and the short-lived Moorestown platform.

Intel "coIOMMU" Can Help With Performance For VMs When Using Direct I/O Access

Currently when directly assigning I/O devices to virtual machines the guest memory needs to be statically pinned unless using a vIOMMU setup in which case it does not but there are performance implications there as well. Intel engineers though have been working on a virtual IOMMU implementation with DMA buffer tracking to overcome these limitations.

Running Intel Tiger Lake On The Linux 5.10 Kernel

Given Intel's very fresh Tiger Lake platform, our latest benchmarking with the Core i7-1165G7 within the Dell XPS 9310 is seeing if running the in-development Linux 5.10 kernel means any performance or power changes for this latest-generation Intel mobile CPU with Xe/Gen12 graphics.

Intel Bus Lock Detection For The Linux Kernel Proceeding

Earlier this year the Linux kernel landed split lock detection for being able to detect and optionally kill processes leading to a split lock since it can cause measurable performance issues and even possible unprivileged denial of service.

Intel's oneDNN Continues Improving Support For Non-Intel Hardware

Earlier this year was the surprising move of Intel's oneDNN neural network library adding AArch64 support and that was then complemented by adding IBM POWER support to this neural network library that is part of their oneAPI collection. Now with the latest oneDNN 2.0 beta they have furthered the support and performance for non-Intel hardware.

Intel Sends Linux Kernel Patches For VRR / Adaptive-Sync Enablement

For months now Intel's open-source Linux driver stack has been preparing for VRR support with Gen11/Gen12 graphics. We've seen user-space patches by Intel around VRR while now they are finally sending out their key Linux kernel driver patches with the i915 DRM code.

Linux Developers Discussing Possible Kernel Driver For Intel CPU Undervolting

While the Intel Extreme Tuning Utility (XTU) on Windows allows for undervolting laptop processors, currently on Linux there isn't any Intel-endorsed way for undervolting your CPU should you be interested in better thermal/power efficiency and other factors. But a hypothetical Linux kernel driver could be coming for filling such void.
