system faulting in pages if it does e.g. fragment reallocation
* get rid of rumpvm_findpage() and always use uvm_pagelookup()
* determine a vnode's cleanness by flagging it as being on the work
list if we "take" a write fault and removing it from the worklist
once pages are flushed. There is no work list here, but at least
there is symmetry with the kernel.
ffs in userspace on top of puffs/p2k/rump is now stable enough to
host a make -j4 kernel build (well, at least my kernel build ...
but, yes, I am currently running that kernel on my desktop)
directly instead of relying on a symbol in rumpkern. I would like
to make it call the libc symbol directly, but I don't currently know
how to make it do that MI.
Makes hfs work (on i386), as it avoids endless recursion in bswap64().
Thanks to dillo for the image!
/sys/rump contains programs which run unmodified kernel code in an
emulated userspace environment. The kernel environment is provided
by librump. Currently supported are a number of file systems,
which by using puffs integrate seamlessly into the system and
provide a similar user experience to if the code was running as
part of the kernel. Potential future rumpification targets include
for example parts of the networking stack and some device drivers.
This work was supported by Google Summer of Code 2007.
