Inferno running natively on "x86 super= computer"? I think implementing multicore support would be a first step, no= t to mention 64-bit!

Recalling the issues Hellaphone had and the time it took, I'm of the opinio= n that getting Inferno to work on any given phone's Linux kernel is hardly = more worthwhile than porting it directly to the hardware. The kernels have = undocumented interfaces. A current thread on OSdev (operating system development) forums is looking = at phones.

There are at least 2 phones available now whic= h are fully open for operating system development: the PinePhone and the Li= brem 5. (5 is the screen size.) Of the 2, the Pine Phone seems better, not = least because it can boot from the SD card; useful for testing. https://forum.osdev.org/viewtopic.php?f=3D1&t=3D53251 There's also the option of building your own phone out of components. The t= hread has some info. I'm guessing most here would prefer a PinePhone. > But I think I saw some recent-ish Inferno-on-Android activity here: >=20 > https://github.com/bhgv/Inferno-OS-bhgv That's probably a good source of code. bhgv is a freelance programmer who w= as very interested in Inferno and made several improvements including Truet= ype fonts. The last I heard was he tried to find paid work involving Infern= o but couldn't, so he didn't have time to work on it. ------------------------------------------ 9fans: 9fans Permalink: https://9fans.topicbox.com/groups/9fans/T39aec8f3f9d8503d-Mbb7a2= eb707551c328b09736d Delivery options: https://9fans.topicbox.com/groups/9fans/subscription
