Additionally, support is also introduced for two new "syndrome" MSRs used in newer AMD Scalable MCA (SMCA) systems. Also, a new "FRU Text in MCA" feature that uses these new "syndrome" MSRs has been addded. Patch 1 adds the new wrapper structure mce_hw_err for the struct mce while also modifying the mce_record tracepoint to use the new wrapper. Patch 2 adds support for the new "syndrome" registers. They are read/printed wherever the existing MCA_SYND register is used. Patch 3 updates the function that pulls MCA information from UEFI x86 Common Platform Error Records (CPERs) to handle systems that support the new registers. Patch 4 adds support to the AMD MCE decoder module to detect and use the "FRU Text in MCA" feature which leverages the new registers. NOTE: This set was initially submitted as part of the larger MCA Updates set. v1: https://lore.kernel.org/linux-edac/20231118193248.1296798-1-yazen.ghannam@amd.com/ v2: https://lore.kernel.org/linux-edac/20240404151359.47970-1-yazen.ghannam@amd.com/ However, since the MCA Updates set has been split up into smaller sets, this set, going forward, will be submitted independently. Having said that, this set set depends on and applies cleanly on top of the below two sets. [1] https://lore.kernel.org/linux-edac/20240521125434.1555845-1-yazen.ghannam@amd.com/ [2] https://lore.kernel.org/linux-edac/20240523155641.2805411-1-yazen.ghannam@amd.com/ Changes in v2: - Drop dependencies on sets [1] and [2] above and rebase on top of tip/master.
