According to Rick's reply in this thread a damaged row in a DIMM can easily cause a few thousand entries in the e820 table because it doesn't handle patterns. So the question I'm asking is, is it acceptable to have an e820 table with thousands maybe ten-thousands of entries? I really have no idea of the implications, maybe somebody else can comment on that.
Given that that is what actually ends up happening in the kernel at some point anyway, I don't see why it would matter. The bubble sort has to go, but quite frankly stress-testing the range handling isn't a bad thing. -hpa -- H. Peter Anvin, Intel Open Source Technology Center I work for Intel.
