Intel Granite Rapids Brings New "SBAF" Core Testing Capability
Upcoming Intel Xeon 6 'Granite Rapids' processors will support a new Structural Based Functional Test at Field (SBAF) testing capability to help verify the health of the CPU cores.
The past two years Intel Linux engineers have been developing the In-Field Scan(IFS) driver that since Xeon "Sapphire Rapids" processors has supported a means of help verifying the CPU's health and spotting any silicon defects either prior to commissioning new servers or reaffirming the silicon's health after deployment in an ongoing basis. In-Field Scan is especially valuable for hyperscalers, cloud providers, and others for verifying the health of CPUs via various functional tests that can be carried out on the processor internals at the choosing of the administrator. It makes use of Design For Test (DFT) observation sites and features to maximize coverage in minimum time.
