Reply To: Mill vs. Spectre: Performance and Security

Dave, that sound like a solution that could be implemented on any architecture, and adds additional complexities in terms of cache coherency, and adds latency to check in both caches probably.

I am all for QoS or minimum-maximum ranges of allocated cache space (in LLC) per turf, so meory intensive and cache trashing other processes do not completely kill applications that want low latency and some small amount of cache (mostly for code, and a bit of data), that is not constantly evicted on context switches. But I do not think L1 has enough space do do the same for data.
