This implies that ARM vendors do less validation. I guess ARM is just so much simpler that good enough validation can be done faster. So essentially this is payback time for Intel for keeping compatibility with older code and simpler to program architecture (stricter cache coherence etc.). It is like one can only have 2 of cheap, reliable, easy-to-program.
- pkaye 9y agoI'm sure ARM vendors have their own problems... it is just that they tend to be used in application specific products so the bugs are worked around. Having come from a firmware background I've worked are tons of ugly workarounds for serious bugs in validated hardware. Furthermore, I just a read an article (can't find the link) that certain ARM Cortex cores have this same issues as Intel.
- lmm 9y ago> This implies that ARM vendors do less validation. I guess ARM is just so much simpler that good enough validation can be done faster. More likely "good enough" is much lower because ARM users aren't finding the bugs. The workloads that find these bugs in Intel systems are: heavy compilation, heavy numeric computation, privilege escalation attackers on multi-user systems. Those use cases barely exist on ARM: who's running a compile farm on ARM, or doing scientific computation on an ARM cluster, or offering a public cloud running on ARM?
