Intel is enhancing its Linux NPU driver with a new feature for better control over command queues in the upcoming Linux 7.4 release.
Intel is adding a new feature to its Linux driver that lets you change how quickly certain tasks run on Intel's special chips. It's like giving some tasks a higher priority so they get done faster.

Key points
- Intel adds a new command-queue priority feature to its Linux NPU driver
- This feature allows users to dynamically change the priority of command queues
- The feature is part of the Intel NPU driver, which is now officially supporting Ubuntu 26.04 LTS
This feature could help improve the performance of Intel's NPU chips, making them run faster and more efficiently.
However, there could be issues if the NPU firmware doesn't respond quickly enough to changes in priority, which could cause delays in task execution.
