Phoronix reported on November 8, 2026, that AMDXDNA driver changes for AIE4 were targeting Linux 7.5. The reported work covers firmware 6.0 and NPU3 classic devices, along with AIE4 power management, suspend and resume, device queries, and command submission.
AIE4 functions reported for Linux 7.5
The changes described by Phoronix include support for setting and retrieving power modes, suspending and resuming the device, querying clock and DPM frequencies, requesting resource information, and submitting commands. The report also names support for firmware version 6.0 and NPU3 classic devices.
These functions cover several parts of the driver’s interaction with an NPU: managing power states, asking the device for information, and sending it work. They are described as changes aimed at the Linux 7.5 development cycle.
Read the reported feature list by function: power management, device queries, and command submission each describe a different part of the driver’s work.
Earlier work covered AIE4 queues and memory
A separate pull-request message dated October 23, 2026, identified its changes as material for the Linux 7.5 cycle. Its list included work on the AIE4 kernel-queue lifecycle and memory layout. The message is available in the Linux kernel mailing-list archive.
That earlier staging work adds context to the later feature list: the queue lifecycle and memory layout were part of an earlier change set, while Phoronix reported additional AMDXDNA functions on November 8. Both accounts place the work in development for Linux 7.5.
