Brief summary

lspci entry with id 00:16:0 is not Intel ME

How reproducible

100%

How to reproduce

run lspci | grep 00:16:0 with Intel ME enabled

Expected behavior

should find an entry like: 00:16:0 Intel Corporation Meteor Lake Management Engine Interface

Actual behavior

there is an entry: 00:16:0 Communication controller: Intel Corporation Device 7e70 (rev20)

Screenshots

No response

Additional context

I believe the name on the right of the device ID is determined by mapping the device ID to some table of names. This may be an error with this table in the OS, not with the ME.

Solutions you've tried

rebooting

That is entirely OS side, it should have some kind of PCI DeviceID name database. It knows that the PCI VendorID is Intel Corporation, but the DeviceID 7E70 has no actual name associated to it, so it just displays the hex ID.

According to datasheet at 2.3 Device IDs: https://www.intel.com/content/www/us/en/content-details/792044/intel-core-ultra-processor-datasheet-volume-1-of-2.html PCI DeviceID 7E70h located at 00:16.0 (22 in decimal) should be called Intel CSME: HECI # 1. But again, knowing that is on OS side.

Thanks for pointing to the documentation. It sorts out my problem. I wonder if the issue should just be closed or forwarded somewhere else.
