[meta-intel] Skylake SMB support

[Reynolds, Stephen (Abaco Systems, Non-GE)]

That is extremely helpful and I am grateful for your help

I had seen the notes and I was unsure what "Basic IO" covered.

I can wait for 2.1

Regards and Thanks

Steve

I will be honest, I am not sure what you are referring to with the function being moved from 0 1f 3 to 0 1f 4.

While SMB is supported in the HW, The Saddle Brook (Skylake) BSP which is part of the meta-intel and based on the 4.1 kernel does not have full support.  As described in the Release notes for the Skylake BSP (h
ttps://www.yoctoproject.org/downloads/bsps/jethro20/saddle-brook-
skylake)

We in fact will be using the 4.4 kernel for the 2.1 release. The 4.4 kernel supports Lewisburg (PCH), which is the Skylake's Platform Controller Hub. The detailed datasheet is available here: https://urldefense.proofpoint.com/v2/url?u=http-3A__www.in&d=CwIDaQ&c=IV_clAzoPDE253xZdHuilRgztyh_RiV3wUrLrDQYWSI&r=a6kFrEUxQA6pxtL1SdYo5tHdFWdCoUJRX4uqa4kLxTo&m=-z9-oOHAmC7gRSZBZ33KGuiwMLBOHwDRigvlNqfJ_JE&s=m7-kM9EBYin1XYOtlstnx2eTtgwopcLwwmeJQZSV4UU&e=
tel.com/content/dam/www/public/us/en/documents/datasheets/7-series-
chipset-pch-datasheet.pdf

It was also suggested there might be a conflict with the ACPI memory region and that you check the BIOS settings for the ACPI memory region.

Hope this is helpful information

Sau!
