  12. Is Funtoo ready for AMD Ryzen CPUs?

    in General Discussion

    Posted

    it is somehow ready.

    yes, for specific ryzen optimization, you need gcc-6. kernel-4.9 supports zen cpu's already as of 4.9.18 (that's the default kernel in debian unstable and is what funtoo using by default) both debian-sources-4.9.18 and gcc-6.3 already available in portage tree  but masked. debian-sources is ready for unmask, gcc-6.3 still needs more tests.

  21. LLVM Targets

    in News and Announcements

    BPF stands for Berkeley Packet Filter, with this target enabled, llvm will have specific code for this, which is used in some firewalls, etc. It's enabed for generic purposes, you can disable it. 

    NVPTX is rather about nvidia-drivers, not nouveau. It enables specific code needed for CUDA, OpenCl and other code that can be used by gpu chips (nvidia in this particular case). Not sure nouveau does that.

  22. Any chance of a Portage c or c++ version instead of Python in the future?

    in General Discussion

    there is paludis already and which is even slower than original portage -- it doesn't require python but it does require boost -- just an example. I don't think this will fix anything you maybe think it will by porting to another language. The main problem in portage is not that it's written in python but that many parts of it are obscure, undocumented and doesn't look good, highly over-engineered and maybe also recent portage development only in maintenance mode - not in fixing code or development mode. Many blame portage for being slow, partially agreed with that, but, again it's not because it's in python. Remember that good code is good in any language. To summarize - cloning portage in other language will be only a clone, that's rewriting same framework and design in language that can be really bad experience and can result in much worse cases, like paludis. Ultimate fix, maybe, would be creating package manager from scratch.
