Hi Suzuki & Anshuman.
I have some questions about the new ACPI HID for ARM CoreSight ETE
and need to get you help to confirm.
a）Has ARM distributed a new ACPI HID for ETE, or is it plans to do so?
If possible, can the new HID be provided in advance?
b) Or Is it possible to add an new ACPI HID (HISI0461) for HiSilicon ETE.
Best regards, Junhao.

ETE can reuse the same HID as that of the ETM. The ACPI specification change for this is in BETA state, available here :
https://developer.arm.com/documentation/den0067/latest
The TRBE changes are also published with ACPI v6.5. The kernel support is not there yet. We plan to do that soon.
Kind regards
Suzuki
