--layout reports incorrect memory layout for EPYC 7xx2 CPU #64
Comments

The layout as displayed by sysfs is wrong too, so this may be more a kernel issue than anything else. |

First of all, it is not every time that the BIOS information is correct. It is actually common that the same BIOS is used on different machines that have different motherboard silk screen and/or different numbers of sockets. So, neither the Kernel nor rasdaemon relies on it. If the BIOS is reliable enough, one could use: With such information (that comes from DMI decoding), it can update the layout that are inside the |
