Security, Performance, Power Savings.
Pick one, per cache domain.
I actually support additional, cache-isolated, //USER OWNED// TPM / enclave like solutions for running the hardened parts of software (handling of actual keys/etc). 99% of the other work is better off picking the speed or power efficiency options.
(Edit to clarify User Owned: The end user should trust the computer, not anyone else, therefore they should be the one with full control, not any vendor or imaginary property creator.)
- swiley 8y ago> //USER OWNED// TPM / enclave HAHAHAHAHA That would be kind of neat if it ever happened though.

- als0 8y agoA TPM is user owned by design. It is opt-in, you can delete the contents and create your own keys, password protect access etc.
