Greetings all HelenOS admirer and occasional experimenter here.
Re windowing systems: There is a much better exemplar, much closer to hand, in the Haiku project. Backporting 30(?) years of Linux/Unix/Windows cruft is a terrible use of scarce resources. Much better to get the basics into place - like knowing a networked VM instance will actually interop with other systems on that network. Or, how to port HelenOS to 'smaller' machines. I'd really like to see a core that would boot a multi-core ARM/ARM64 system ... for embedded/appliance work this could be fantastic stuff. Just saying 😊 If anyone has specific ideas about resourcing in these contexts please send me an email.

But would much less, if to know how once written driver for linux to port into HelenOS (with redesign for the Helen requerements kernel specifics of course). Would be cool if someone with experience of the HelenOS developing wrote alike step-by-step manual... Next step: to write Graphical System, e.g XWindows, but without low-level requests to the server show/hide/top basic rectangles, - directly to have thread safe c++(or C) interface for creating surfaces for drawing. Last step: to port GTK, FLTK, WxWidgets to the HelenOS, - after the OS will be colonized by existing programms. The sense: High quality developers gives ways to do things for less quality programmers (righter will be to say: other programming orientation) - introducing into their competention area for other programmers. For newly arrived programmers to have intro: Do you want to support your HW for the HelenOS ? - see this manual, do work, send to the team the patch ... Sorry for my wishes :) -- the best regards 2018-12-19 20:21 GMT+05:00, Vojtech Horky <[email protected]>: > Hello, Dmitrij, > > I think your assumptions about HelenOS are too optimistic ;-) > > st 19. 12. 2018 v 11:50 odesílatel Dmitrij V <[email protected]> napsal: >> To write HW GPU drivers by scratch is titanic work ! - easier to stay >> in linux space without attempts to look to other sides(OS).
