sf4k, multi-core edition

[tbp]

Ah! The wonders of boredom. I must say making calls to sys_clone inlinable proved to be rather, hmm, interesting; i've wisely used the saved bytes to add a progress bar. Yay.

Now the question is does this really work anywhere but one my boxen. Hence the post. As a true color framebuffer is required, at least in the 'release' mode, and dimensions are hardcoded (but automatically), i've bundled a small thingy to probe.
While demo binary should work on any kernel >=2.4, you'll most certainly have to recompile the prober.

I doubt you care but I can't run it in virtual machine as it doesn't have /dev/fb*
Also fbinfo is 64bit so it cannot run on 32bit machines.

Will try later at home on 64bit box.

Oh but i do care, that was the reason for posting

sf4k is wired to 32bit mode, for size reasons, but the 'prober' - fbinfo - isn't (either to 32 or 64) . But then it needs, unlike sf4k, a c/c++ lib etc... and it's not statically linked (btw source is of course bundled).

About the VM, you may get away with prehistoric vga emulation + fb module. Hmm.

Note: it compiles at least with g++ 4.2, but 4.3 gives better results.

Unfortunately it seems my kernel doesn't have FB support and I doubt I will recompile it any time soon. Sorry, cannot check your program

QEmu + Knoppix = success.
