accel/amdxdna: Use a different name for latest firmware

2026-02-25T21:51:31Z

Using legacy driver with latest firmware causes a power off issue. Fix this by assigning a different filename (npu_7.sbin) to the latest firmware. The driver attempts to load the latest firmware first and falls back to the previous firmware version if loading fails.

accel/amdxdna: Poll MPNPU_PWAITMODE after requesting firmware suspend

2025-12-03T00:31:14Z

After issuing a firmware suspend request, the driver must ensure that the suspend operation has completed before proceeding. Add polling of the MPNPU_PWAITMODE register to confirm that the firmware has fully entered the suspended state. This prevents race conditions where subsequent operations assume the firmware is idle before it has actually completed its suspend sequence.

accel/amdxdna: Add hardware specific attributes

2025-11-04T17:01:44Z

Add three hardware specific attributes to describe device capabilities: hwctx_limit: The maximum number of hardware context supported. max_tops: The maximum TOPS supported. curr_tops: The TOPS achievable with the current power and frequency configuration.

accel/amdxdna: Use MSG_OP_CHAIN_EXEC_NPU when supported

2025-11-03T17:20:39Z

MSG_OP_CHAIN_EXEC_NPU is a unified mailbox message that replaces MSG_OP_CHAIN_EXEC_BUFFER_CF and MSG_OP_CHAIN_EXEC_DPU. Add driver logic to check firmware version, and if MSG_OP_CHAIN_EXEC_NPU is supported, uses it to submit firmware commands.

accel/amdxdna: Enhance power management settings

2024-12-16T21:50:32Z

Add SET_STATE ioctl to configure device power mode for aie2 device. Three modes are supported initially. POWER_MODE_DEFAULT: Enable clock gating and set DPM (Dynamic Power Management) level to value which has been set by resource solver or maximum DPM level the device supports. POWER_MODE_HIGH: Enable clock gating and set DPM level to maximum DPM level the device supports. POWER_MODE_TURBO: Disable clock gating and set DPM level to maximum DPM level the device supports. Disabling clock gating means all clocks always run on full speed. And the different clock frequency are used based on DPM level been set. Initially, the driver set the power mode to default mode.
