Dose linux make use of the MTRR (memory type range registers), specifically
with relation to SMP and memory? According to the intel maual for the pentium
families MTRRs can be used to set how strong/weak the memory ordering is on
blocks of ram (I.E. the "shared" memory could be strong ordered to keep
consitency while each processor could have it's own scratch area that is weakly
orded to improve speed).
If it does, is there a standard mechanism for a kernal process to set / change
the entries?
