[PATCH 0/2] faking and fixing the NUMA SLIT

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The problem with NUMA distances in the SLIT is that they are often wrong, oh 
wait they aren't there at all because the BIOS didn't create a SLIT since 
Windows does not use it.  If Linux does not find a slit it just says the 
distance to local=10 and remote=20 according to ACPI spec.  The problem is 
when we have a 4P system (or larger), there is generally one node where we 
have two hops and its distance should be >20.

Following are patches to first fake the SLIT in the ACPI code and then add 
ability to write the distances from sysfs.
