This patch adds support for ECC error decoding for F15h M60h processor.
Aside from the usual changes, the patch adds support for some new features
in the processor:
- DDR4(unbuffered, registered); LRDIMM DDR3 support
- relevant debug messages have been modified/added to report these
memory types
- new dbam_to_cs mappers
- if (F15h M60h && LRDIMM); we need a 'multiplier' value to find
cs_size. This multiplier value is obtained from the per-dimm
DCSM register. So, change the interface to accept a 'cs_mask_nr'
value to facilitate this calculation
- switch-casing determine_memory_type()
- done to cleanse the function of too many if-else statements
and improve readability
- This is now called early in read_mc_regs() to cache dram_type
Misc cleanup:
- amd64_pci_table[] is condensed by using PCI_VDEVICE macro.
Testing details:
Tested the patch by injecting 'ECC' type errors using mce_amd_inj
and error decoding works fine.
