Intel NPU Linux Driver Adding Command-Queue Priority ioctl For Linux 7.4
The latest drm-misc-next pull request introduces a new command-queue priority ioctl for Intel NPU Linux drivers targeting the Linux 7.4 kernel. This feature allows users to dynamically adjust the scheduling priority of existing command queues on Intel Core Ultra SoCs. The update is part of a broader set of low-level code improvements and minor hardware support additions included in this week's DRM material.
- ▪The new DRM_IVPU_PARAM_CMDQ_PRIORITY ioctl enables querying and updating the scheduling priority of Intel NPU command queues.
- ▪This feature allows for dynamic priority changes on command queues that already have pending jobs.
- ▪The NPU firmware is designed to respond to these priority updates at the first available opportunity.
- ▪The update is included in the drm-misc-next pull request for the upcoming Linux 7.4 merge window.
- ▪Other changes in this pull include R-Car V4H DSC support and Solomon SSD1351 OLED driver updates.

Add A Comment Sent out today was the latest weekly drm-misc-next pull request of new Direct Rendering Manager (DRM) material ready for the upcoming Linux 7.4 merge window. For end users there isn't too much to get excited about with this week's drm-misc-next pull with just some low-level code improvements and internal changes to the smaller DRM drivers. There is R-Car V4H DSC for the RCar-DU driver and the ssd130x driver has Solomon SSD1351 OLED support for new hardware support this week. For those making use of Intel's NPUs with Core Ultra SoCs, one new feature landing via the drm-misc-next pull is a new command-queue priority ioctl.
