pooka 0c2778236c Don't create the percpu clock interrupt threads as softint threads because they aren't softint threads. This fixes callouts in situations where there is nothing else happening in the rump kernel (i.e. no threads executed which would trigger the softints when they unschedule).		2010-08-10 21:32:38 +00:00

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
