<Hagfish>One interesting aspect are timing channels. We have been working for a number of years on *time protection*, the temporal equivalent of memory protection, as a systematic timing-channel prevention. Our experience on x86 and ARM processors is that they lack the mechanisms to do this completely. RISC-V presents an opportunity to get this right
<fossy>Nice
<fossy>let me ask my dad about this
<fossy>he knows some of the ppl who worked on it
<OriansJ`>stikonas: done
<OriansJ`>Hagfish: well if I remember the reason for why x86 and ARM don't support it is due to the performance penalties on OoO processors is brutal and superscalar processors take a beating on branching performance.
<stikonas>ok, thanks!
