Palacios Public Git Repository
To checkout Palacios execute
git clone http://v3vee.org/palacios/palacios.web/palacios.git
This will give you the master branch. You probably want the
devel branch or one of the release branches. To switch to the devel
branch, simply execute
cd palacios
git checkout --track -b devel origin/devel
The other branches are similar.
Expose vmalloc-like os interface to Palacios, and updates to use it
The purpose of finally exposing virtually contiguous /
not necessarily physically contiguous allocations to Palacios
is to get around a catch-22. We support arbitrarily small
base region chunks at this point, down to a page size. We
also support host kernels that do not provide large contiguous
physical page allocations. The result is that we can
end up needing to build a base region chunk array that is
larger than the amount of memory we can either malloc or
contiguously page alloc to support it. Yet the base region
array itself does not need to be physically contiguous.
Two places where this currently burns us is: large memory
VM allocated over linux host that does not support hot remove;
moderate memory VM using tiny chunk size, for example in
cache partitioning
