Subject: [QUESTION] EDAC/igen6: Missing PCI ID for Intel "Arrow Lake-S" Host
 Bridge (8086:7d1a)

Hello,

I am running a system with a new Intel "Arrow Lake-S" CPU (Core Ultra
9 285T) on an ASRock IMB-X1317-10G motherboard, which supports In-Band
ECC.

I have confirmed ECC is enabled in the BIOS, and dmidecode reports an
80-bit total width, so the hardware is active.

However, the igen6_edac driver fails to attach, and edac-util reports
"No memory controllers found."

I've diagnosed the issue:

1. My CPU's Host Bridge PCI ID is [8086:7d1a] (from lspci -nn -s 00:00.0).

2. I checked the igen6_edac driver's latest source, and this PCI ID is
missing. The driver has support for "Arrow Lake-UH" (e.g., 7d06) and
even future "Wildcat Lake" CPUs, but not the "Arrow Lake-S" desktop
variant.

Is adding the 8086:7d1a PCI ID for Arrow Lake-S on the roadmap?

Thank you.
