Subject: [libre-riscv-dev] Avoiding Spectre or Meltdown
Date: Mon, 18 May 2020 09:03:19 -0400
Message-ID: <33B8ACFA-9A9F-482F-985B-D5E5C44B56B9@gatech.edu> (raw)
I know Jacob mentioned some scheme earlier.
If you shadow commits to memory(really cache) during speculation by having commits placed in a buffer, which you can ignore once branch is resolved, wouldn’t that avoid some problems with Spectre and Meltdown?
