I'm wondering if its possible to disable HT-Assist feature on Opteron 6200 series CPU. I've searched around BIOS and around the web but can't find anything.
Reason why I would like to disable it is that Opteron 6200 series CPUs should have 16 MB L3 Cache, however 4MB is reserved for HT-Assist, so only 12MB L3 is OS usable. For my use case it would be beneficial to gain additional 4MB L3.
Wondering if anyone has figured out how to do this. Thanks.
