I note that I *really like arm*, going back a very long ways. http://the-edge.blogspot.com/2002/06/axioms-one-of-my-axioms-about.html I remember telling the CTO of palm they were doomed back then... they had started trying to differentiate models by *color* at that point.... sure the abi and compiler "were out there" - but getting 20,000 packages converted over and widely into a popular distro and platform, to me, was the tipping point for wider adoption of the hard float abi, as something others could build on. I just spent a few minutes googling for that story, but couldn't find it (what I remember was 3 guys, 3 months, hammering at getting 20,000 packages to all "just work"). What we had before was a mess of different ABIs, and a whole bunch of slightly incompatible arm cpu versions - all enough different to fragment the arm ecosystem. there was no way you could trust one binary on a different box. Back around this time (2006-2010?) it was also unclear that arm would accellerate so far past the herd, either, and there were a ton of other factors, of course that led to where it's now being considered for supercomputers and looks set to start unseating intel in many places. And despite really liking arm, I look forward to entirely new arches like the risc-v and mill eating its lunch one day. Things like trustzone, the mali gpu, and other portions of onchip IP commonly shipped with the chips suck rocks, still. Very few applications are taking good advantage of the neon vfp code, the onboard caches are way behind intel's, and so on... speaking of trustzone - yea! there's a way to use it now. https://github.com/OP-TEE > > -- Juliusz --=20 Dave T=C3=A4ht Let's go make home routers and wifi faster!
