Read DLA usage (percentage, frequency) on AGX Orin on Jetpack 6.1

Hi, we are using JetPack 6.1 on a Jetson AGX Orin 64GB. We are trying to get DLA0 & DLA1 usage (percentage, frequency), but seems like these metrics are not exposed in sysfs:

# ls /sys/devices/platform/bus@0/13e00000.host1x/15880000.nvdla0
clk_cap          power
driver           subsystem
driver_override  supplier:platform:2c00000.memory-controller
iommu            supplier:platform:2c60000.external-memory-controller
iommu_group      supplier:platform:8000000.iommu
modalias         supplier:platform:bpmp
nvdla0           uevent
of_node

Found this similar post: DLA usage percentage and frequency reporting in tegrastats tool . Looks like for JetPack 5.0, only PM runtime status metric is available for DLA for Orin. Is it still the same for JetPack 6.1?

Based on the provided context, it appears that the Jetson AGX Orin series devices have power management features that are visible to software, including tools and techniques for managing power consumption.

Regarding the specific question about getting DLA0 and DLA1 usage percentage and frequency on a Jetson AGX Orin 64GB with JetPack 6.1, it seems that these metrics are not exposed in sysfs.

According to the context, for JetPack 5.0, only the PM runtime status metric is available for DLA on Orin. Although the question is about JetPack 6.1, it is likely that the situation is still the same, and these metrics are not exposed in sysfs.

However, the context mentions that the tegrastats tool can report DLA usage percentage and frequency for JetPack 5.0. It is possible that this tool may also work for JetPack 6.1, but this is not explicitly stated in the context.

In comparison, the context provides information on how to get and set frequencies for the GPU on the Jetson AGX Orin series devices using sysfs. Specifically, it mentions that the available frequencies can be listed using the command cat /sys/devices/platform/17000000.gpu/devfreq/17000000.gpu/available_frequencies.

Additionally, the context provides information on power monitoring and management features for the Jetson AGX Orin series devices, including the use of INA3221 power monitors and the configuration of TDP power budgets and OC limits.

In summary, while the specific metrics for DLA0 and DLA1 usage percentage and frequency may not be exposed in sysfs for JetPack 6.1, the tegrastats tool may be able to report these metrics. Further investigation is needed to confirm this.
