History

dyoung 64311e1f9d Introduce a couple of new constants, VMEM_ADDR_MIN (the least possible address in a vmem(9) arena, 0) and VMEM_ADDR_MAX (the maximum possible address, currently 0xFFFFFFFF). Modify several boundary conditions so that a vmem(9) arena can allocate ranges including VMEM_ADDR_MAX. Update documentation and tests. These changes pass the tests in sys/kern/subr_vmem.c. To compile the and run the test program, run "cd sys/kern/ && gcc -DVMEM_SANITY -o subr_vmem ./subr_vmem.c && ./subr_vmem".		2011-08-23 22:00:57 +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
