Hi Ashmita,

Broadwell-DE / Xeon D support still depends Intel's closed-source FSP (Firmware Support Package) binary-only blobs.

Broadwell-DE SoC / Xeon D Support Added To Coreboot

Hope you could configure them through fsp_upd_data?

Regards

Ranga

Dear Ranga,

These options are meant for Xeon D-15xx series family. So will the coreboot support these options? The coreboot will be built for Xeon D-15xx processor. Yes, I have access to them in fsp_early_init through fsp_upd_data.

Thanks&Regards,

Ashmita Chakraborty

Hi,

As these features are processor/SoC specific and they are part of FSPM, they should be configurable

during fsp early init in coreboot, though you may not find a KConfig option to enable/disable

Do you have access to them in fsp_early_init through fsp_upd_data?

Regards

Ranga
