The following is a quick rundown of the current directory structure.
First, components in the kernel namespace, i.e. compiled with -D_KERNEL
sys/rump/librump - kernel runtime emulation
/rumpkern - kernel core, e.g. syscall, interrupt and lock support
/rumpcrypto - kernel cryptographic routines
/rumpdev - device support, e.g. autoconf subsystem
/rumpnet - networking support and sockets layer
/rumpvfs - file system support
sys/rump/include
/machine - used for architectures where the rump ABI is not yet the
same as the kernel module ABI. will eventually disappear
completely
/rump - rump headers installed to userspace
sys/rump/dev - device components, e.g. audio, raidframe, usb drivers
sys/rump/fs - file system components
/lib/lib${fs} - kernel file system code
sys/rump/net - networking components
/lib/libnet - subroutines from sys/net, e.g. route and if_ethersubr
/lib/libnetinet - TCP/IP
/lib/libvirtif - a virtual interface which uses host tap(4) to shovel
packets. This is used by netinet and if_ethersubr.
/lib/libsockin - implements PF_INET using host kernel sockets. This is
mutually exclusive with net, netinet and virtif.
The rest are out-of-kernel components (i.e. no -D_KERNEL)
related to rump.
hypercall interface:
src/lib/librumpuser
The "rumpuser" set of interfaces is used by rump to communicate
with the host.
Users:
src/lib
/libp2k - puffs-to-vfs adaption layer, userspace namespace
/libukfs - user kernel file system, a library to access file system
images (or devices) directly in userspace without going
through a system call and puffs. It provides a slightly
higher interface than pure rump syscalls.
src/usr.sbin/puffs
rump_$fs - userspace file system daemons using the kernel fs code
src/share/examples/rump
Various examples detailing use of rump in different scenarios.
These are provided source-only.
