Disabling VT-d improves Intel Arc GPU Linux performance on Meteor Lake and newer SoCs

Improve Intel Arc GPU performance Linux VT-d disabled

In this post, I’ll check whether disabling VT-d virtualization support may improve the performance of the Intel Arc GPU in recent Meteor Lake or Lunar Lake SoC using a Khadas Mind Maker Kit with an Intel Core Ultra 7 258V CPU with Intel Arc 140V graphics running Ubuntu 24.10. A few days ago, I read a post on Phoronix about Intel publishing tips to improve the performance of Intel GPUs in Linux: Keep the system updated with the latest kernel and Mesa versions. Ensure SoC firmware is up-to-date. These firmware updates currently require installing the Windows graphics driver; firmware updates via fwupd are in progress. Use Wayland where possible, as it supports additional modifiers for better performance. For MTL (Meteor Lake) and newer integrated GPUs, disable VT-d if virtualization is not needed. For discrete GPUs: Enable ReBAR_ Enable ASPM_ I was especially curious about the line about disabling VT-d virtualization […]

SONOFF MINI-D Review – A Matter-enabled dry contact WiFi switch tested with eWeLink, Home Assistant, and Apple Home

SONOFF sent us a sample of the MINI-D Wi-Fi smart switch with a dry contact design for review. If you’re familiar with the larger SONOFF 4CH Pro model, which features four channels, the MINI-D operates similarly but is smaller in size and comes with the latest software features. The principle of a dry contact is that the relay contacts are not directly connected to the device’s power supply circuit. Instead, the contacts are isolated and require an external power source to supply power to the load. Make it flexible to use the SONOFF Mini-D in various scenarios such as controlling garage doors, thermostats, or high-current electrical devices through a contactor, like water pumps. It can also manage low-power DC devices such as solenoid valves or small electric motors (<8W). Because the power supplied to the MINI-D and the power passed through its relay can come from different sources, it offers […]
