May 17 03:40:17 <pabs3> search for Qualcomm in here, interesting stuff: https://news.ycombinator.com/item?id=17081684 
May 17 07:29:59 <DocScrutinizer05> pabs3: the whole thing is damn interesting, at least it explains a few things better than I prolly could
May 17 07:34:11 <DocScrutinizer05> would be interesting to get a few docs about (particularly snapdragon) TrustZone implementation. I only know the ARM basics
May 17 07:34:46 <DocScrutinizer05> and the little bit you can find about OMAP3 TZ / M-Shield
May 17 08:01:49 <PaulFertser> pabs3: what's strange about it is that it's not actually explained how that IZat communicates with the external Internet hosts. It's obvious that it could do that but how exactly that happens? Does that "trustzone os" have its own TCP/IP stack? How modem actually allows concurrent access to data transmission?
May 17 08:43:43 <DocScrutinizer05> must use a userland proxy/daemon of sorts for the data access. Unless it uses RRLP
May 17 08:45:59 <DocScrutinizer05> TZ processes could implement a totally hidden bridge between modem and that GPS+othercrap chip. Maybe the GPS correlation even is done on APE in secure world
May 17 08:46:40 <DocScrutinizer05> iirc GTA01 hammerhead(?) did a similar approach, only in user world
