Do you have access to these machines to load the ie31200_edac
driver with your patch? If yes, would you take dmesg logs?

I didn't find the place in your spec above that indicates these
two CPUs with these two DIDs have Out-Of-Band ECC capabilities.
Could you point it out to me?

I have access to a i5-12600K, here are the logs that I observed:

$ dmesg | rg -i -e edac -e ecc -e ie31200 | rg -v systemd | rg edac
[   14.379905] caller ie31200_init_one+0x1b5/0x480 [ie31200_edac] mapping multiple BARs

I posted additional logs from sysfs and "ras-mc-ctl" here[0] after I learned that support was added for related processors as well as discussion with other users trying to get W680 + ECC working.

This Intel CPU page[1] lists ECC memory support and the same on the Intel W680 chipset page[2]. The datasheet was used to confirm the DIDs[3] were valid.

Given that you added the i9-12900k (0x4660) in 180f091224a00 and I've personally verified the i5-12600k (0x4648) is working (see dmesg logs above), I've added the i7-12700k (0x4668) to assist future users.

Thanks!

Hi Qiuxu and Borislav,

I saw a pull request[0] for a 14th gen version of the same chips and would love to get these 12th gen chips included as well.

Anything I can do to help this along?

Thanks for the logs. 
Successfully loading the driver indicated the i5-12600K is ECC capable.

Add a small comment, please.

+#define PCI_DEVICE_ID_INTEL_IE31200_ADL_S_2	0x4668 /* 6P+6E, e.g. i7-12700K */

Ditto.
+#define PCI_DEVICE_ID_INTEL_IE31200_ADL_S_3	0x4648 /* 6P+4E, e.g. i5-12600K */

Thanks for the detailed specs and your verification.
Please add the comments after the new DIDs as mentioned above, other than that LGTM
