From b3ece3a6a231e51c262d67fd47c017970a7dee44 Mon Sep 17 00:00:00 2001 From: Muralidhara M K Date: Fri, 27 Jan 2023 17:04:19 +0000 Subject: EDAC/amd64: Add get_err_info() to pvt->ops GPU Nodes will use a different method to determine the chip select and channel of an error. A function pointer should be used rather than introduce another branching condition. Prepare for this by adding get_err_info() to pvt->ops. This function is only called from the modern code path, so a legacy function is not defined. Make sure to call this after MCA_STATUS[SyndV] is checked, since the csrow value is found in MCA_SYND.
