Mobile OS Flowchart

A comprehensive history of various mobile Linux efforts in one flow chart, I may have missed some things.

Re: Mobile OS Flowchart
 

You sure did :) For example, Palm OS and even Windoze. Comprehensive? Hardly. Kinda Linux-centric :)

Re: Mobile OS Flowchart
 

The point was to be linux centric. Also adding any more would have made it much bigger.

You do know this kind of chart already exists, do you ?

Then say so in the title. Calling it "Mobile OS lowchart" and ignoring half of the mobile OSes is about as arrogant (or at least ignorant) as the website (linked in a thread here somewhere) listing a history of the smartphone - starting in 2007 with the first generation iPhone.

A few questions (since I know **** about this, but am a bit curious)

• Is iOS on the phone based on BSD just as the desktop version?
• What's the relation between firefox os and Android?
• Why is nemo and sailfish on different branches? Isn't sailfish built on nemo which is built on mer?
• What's the roots of symbian?
• How much BSD is there in Android?

I like your chart, Railroadmaster. The second chart posted is also useful but too "busy" and mostly intended to show Tizen's detailed history.

Probably it would be a pain to do this, but what I'd like in the chart is thick lines and thin lines roughly indicating relative contribution of the upstream osses. Also, maybe stick in Harmattan downstream of MeeGo.

Very interesting, I didn't realize Blackberry had any relation to Symbian.

Alright, I looked up RTOS and QNX and realize that's a silly statement. But, still it's nice that you stuck in these outgroup branches.

Re: Mobile OS Flowchart
 

It actually hasn't, apart from the fact that they both are based on an real-time kernel. Symbian has it's roots in Psion's EPOC16 and EPOC32 operating systems, and in fact wasn't a real-time os before the introduction of the EKA2 (EPOC Kernel Architecture 2) kernel in symbian 8.1. Blackberry uses QNX, which has been an RTOS since it's beginning and shares no roots with either EPOC or Symbian. The chart is a bit misleading in this respect.
