Would "flushing on ignore" not leave the cache side channel open for many instructions before the abort?
Firstly, thanks for the question. As mentioned, not a CPU designer or trying to teach Intel what to do. More like relying on the hive mind to see if I have the right idea. A second instruction in the pipeline would read…
Not a CPU designer, but my guess is that they will move the cache management logic from the MMU to the µOP scheduler, which will commit to cache on retirement of the speculatively executed instruction. They would then…

This is not a SKU to play with. If $20/hr is indeed the price (I don't know), this is the hourly cost of a couple of waiters. You get to run SAP on someone's infra and someone to support it.
Disclosure: I work at Microsoft, I have worked for Microsoft before and quit, and come back. I love the company, but I am no zealot (tried to standardize a company on Macs during my six years away, because it made…
