Hi folks, i know its a kind of off topic, but i think this is the perfect list for this..
anyone here think a little bit like me, and like the exokernel idea? the primary idea is to leverage only things like schedulling, and drivers to kernel ring .. and downgrade things like VFS and MM to userland rings as library.. so an aplication could optionally use those as libs abstracting things generically.. (like a bicicle with wheels)... and when you really need or want.. you can go into the bare metal and create your own application abstraction.. imagine what it could represent in performance since the layers get optimized and are not on top of other layers... and without the context switch between user an kernel ring?? for a applicartion virtual machine like java(with its own schedulling, mm and fs layers), or a database (fs and memory layers) or a virtualization software.. if we write a database for instance and want to outperform disks, the actual scenario is: or you invade the kernel of the OS and implement your abstraction(you has to know all the sou rce of it) and part you code in the userland :s , or you dont mess with the kernel at all (its too impratical) and keep in the userland.. and everybody has to be ruled by only one homogenic way to "see" things.. your application may have luck.. this kernel abstraction its good for you.. but you may has not.. and even if you can see the gold.. you cant advance any further.. the mit guys create one based on 98 (i think) openbsd, and they created a web server that (now optional) tcp protocol where persisted on disk, so its protocol agnostic, and can change its communication wall in runtime.. sometimes im looking to where evething is going in technology, and we are kind of stepping back.. putting more layers on top of others layers... and slowing everything.. instead of getting it faster as it can.. i would like to share experience and what you think about this.. would it be a feasible project to borrow things from freebsd, and start a project like this? anyone like this idea ?? anyway, just some thoughts for now.. _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "freebsd-hackers-unsubscr...@freebsd.org"
