Hi Hawking,

The goal here was to know about the TA versions from just the dmesg only, its helpful as we don't have to ask the user to query data again as dmesg is the first thing that is usually shared for issues.

For now I will add it to the debugfs.

Specific for your case, you just need add dtm and hdcp ta version in 
amdgpu_debugfs_firmware_info, Similar as xgmi and ras ta. The following cmd 
will give you all the firmware version information.

sudo cat /sys/kernel/debug/dri/x/amdgpu_firmware_info

Regards,
Hawking

Hold on please.

I don't think this is the best approach as we already had existing debugfs 
interface for that purpose. We shall centralize all the firmware information 
query under amdgpu_debugfs_firmware_info, and user should go through debugfs to 
query firmware information.

Hawking

It is helpful to know what version the TA's are for debugging
