How can I obtain the current TSC value on DRIVE AGX Thor?

DRIVE OS Version: Provide DRIVE OS version. Example: 7.0.3

Issue Description:
Hi Nvidia,

According to the following forum post, the current TSC can be read using:
devmem2 0x0c6a0010 → Low 32 bits
devmem2 0x0c6a0014 → High 32 bits

This works on DRIVE AGX Orin, but on DRIVE AGX Thor the access hangs and no value is returned.

Are these TSC register addresses still valid on DRIVE AGX Thor?
If not, what is the recommended way to obtain the current TSC value on Thor?

Dear @shoji.watanabe.01 ,
Could you check with NvpGetTimeMark (
