[Xen-devel] [GSoc] Adding Floating Point support to Mini-OS

[Felix Schmoll <eggi.innovations@xxxxxxxxx>]

Hi,

while looking at this some more I came to the following questions/assumptions, so I'd be grateful if you could shortly address them:

-While implementing our own kernel last semester me and my team-mate came to believe that pusha/popa were faster that pushing/popping the individual registers, since it is just a single command. The Mini-OS kernel however does the latter. Is that a conscience performance-trade for something or did we just underly a misconception, in that it compiles to the same thing in the end?

-Lazy floating point register saving is similar to Copy-on-write, is that correct?

-There is nothing preventing me from using some floating-point library for the user-space test program, right?

I'd also appreciate if you could have a quick glance my updated proposal (on the GSoC portal) and give me some more feedback on it.

Thanks

Felix
