KernelVersion: 6.11

|
|
Description: Time in microseconds that the device spent executing jobs. The time is
|
|
counted when and only when there are jobs submitted to firmware. This time
|
|
can be used to measure the utilization of NPU, either by calculating the
|
|
difference between two timepoints or monitoring utilization percentage by
|
|
reading periodically. Recommended read period is 1 second to avoid impact
|
|
on job submission performance. Read-only.

Description: Current NPU memory utilization in bytes. Reports the total size of all
|
|
resident buffer objects allocated for NPU use. Read-only.

Description: Minimum frequency in MHz supported by the NPU hardware. This is a
|
|
hardware capability and cannot be changed. Read-only.

|
Description: Most efficient operating frequency in MHz for the NPU. This represents
|
|
the frequency at which the NPU operates most efficiently in terms of power
|
|
and performance. Read-only.

|
hardware capability and cannot be changed. Read-only.

KernelVersion: 7.2

Contact: dri-devel@lists.freedesktop.org
|
|
Description: Current operating frequency in MHz of the NPU. The value is valid only
|
|
when the device is active; returns 0 when idle. The actual frequency may
|
|
be lower than the requested range due to power or thermal constraints.
|
|
Read-only.

KernelVersion: 7.2

|
Contact: dri-devel@lists.freedesktop.org
|
|
Description: Configured minimum operating frequency in MHz (50XX devices and newer).
|
|
Values written are clamped to hardware limits (hw_min_freq to hw_max_freq).
|
|
If set_min_freq exceeds set_max_freq, the driver clamps set_min_freq to
|
|
set_max_freq when selecting the operating frequency. Read-write.
