[Ofmfwg] OFMF meeting minutes for 12 August 2022

[Sandur, Atul]

[AMD Official Use Only - General]

Hi everyone

Please find attached with this mail an updated version of the document sent by Michael in the previous mail for CXL FM integration with OFMF (Cxl-OFMF-integration-v4.docx). It describes the initial resource discovery workflow, based on which the Redfish data model for CXL use cases is discussed in the Powerpoint slides (also attached).

We are extending the Word doc with the workflow for binding host to FAM node. We were previously blocked on how the host capabilities attached to each CXL switch port can be known. It is helpful to know during the last meeting that this is an open item, we can call it out and complete the rest of the workflow details for now.

Thanks
Atul
