pooka b6c13d8580 * at least try to query size of non-regular size=host files too, 
give up if we get 0
* fix a few error messages
 2011-02-22 15:51:59 +00:00
pooka 29d11b7713 add command line options for kernel memory allocation limit and bootverbose 2011-02-21 18:50:21 +00:00
pooka 090a5e7d74 Use "host" instead of the slightly more cryptic "e" to indicate 
that the size of the mapping should be taken from the host file
size.
 2011-02-18 09:54:03 +00:00
pooka f6adb4bdd8 Use "size=e" as a way say "if the underlying file is preexisting 
regular file, use whatever size it has".
 2011-02-17 16:59:46 +00:00
pooka aaf2cb63d0 Make it possible to specify the type of file (blk/chr/reg) that a 
mapped file (-d) is exposed as within the rump kernel.
 2011-02-17 16:03:05 +00:00
pooka 74135a6c04 Allow to specify -d hostpath offset,size with disklabel. 2011-02-04 20:06:23 +00:00
pooka a9061c30c5 Create backing image with mode 0644 instead of 0755 & document this. 2011-02-03 11:25:27 +00:00
pooka ed37916e33 * make it possible to specify an offset in -d 
* truncate -d hostpath only if it's a regular file and smaller
  than offset+size
 2011-02-03 11:21:16 +00:00
wiz 23e235307b Fix usage (8th bit begone!) 2011-01-03 12:18:25 +00:00
pooka 6fd00c3f62 Add -c to control the number of CPUs configured in the kernel. 2011-01-03 10:44:40 +00:00
pooka bd7256bb7c Guard against supplying the same parameter multiple times in one -d argument. 2010-12-15 19:07:43 +00:00
wiz 77b9f93f9e Sort options in usage same as in man page. 
While here, replace \xa0 with ' '. Where do you get these from?
 2010-12-15 09:40:21 +00:00
pooka dbc10b5a41 Add -d which can be used to register host-backed block devices in 
the rump kernel.

It would be cool if this, and the other options, could be specified
in a config file (plist or other).
 2010-12-14 16:40:05 +00:00
pooka dde3f793dc Also support ld syntax in -l. 
was: -l librumpvfs.so
now: -lrumpvfs
 2010-12-13 14:26:22 +00:00
pooka d3ab3ede2e Add -m which can be used to load modules (which is a completely 
different code path than using dlopen() before rump_init(), since
the former uses the in-kernel linker and the latter links the object
in rtld).

So:
golem> ./rump_server -l librumpvfs.so -m /sys/modules/tmpfs/tmpfs.kmod unix:///tmp/commsuck
==>
golem> env RUMP_SERVER=unix:///tmp/commsuck rump.modstat
NAME             CLASS      SOURCE     REFS  SIZE     REQUIRES
suser            secmodel   builtin    0     -        -
tmpfs            vfs        filesys    0     16713    -
wapbl            vfs        builtin    0     -        -

Source is filesys instead of builtin, as expected.

Notably, for -m you *must* use -l librumpvfs.so.  This is because
you need VFS in your kernel to be able to load modules from the
file system.  In a regular kernel "librumpvfs.so" is linked at
kernel build time and loaded by the bootloader.  Here we use dlopen()
for both effects (the other choices would have been to link
rump_server with -lrumpvfs, but that would limit the flexibility,
or link tmpfs.kmod directly into the binary, but that would limit
the flexibility even more).
 2010-12-13 14:13:21 +00:00
pooka ac0678fe1e Handle -l which dlopens libs. This is more applicable to rump_server 
than rump_allserver.

So if I do:

golem> rump_server unix:///tmp/commsuck
==>
golem> env RUMP_SERVER=unix:///tmp/commsuck rump.modstat
NAME             CLASS      SOURCE     REFS  SIZE     REQUIRES
suser            secmodel   builtin    0     -        -

and:

golem> rump_server -l librumpvfs.so unix:///tmp/commsuck
==>
golem> env RUMP_SERVER=unix:///tmp/commsuck rump.modstat
NAME             CLASS      SOURCE     REFS  SIZE     REQUIRES
suser            secmodel   builtin    0     -        -
wapbl            vfs        builtin    0     -        -

golem> rump_server -l librumpvfs.so -l librumpfs_ffs.so unix:///tmp/commsuck
==>
golem> env RUMP_SERVER=unix:///tmp/commsuck rump.modstat
NAME             CLASS      SOURCE     REFS  SIZE     REQUIRES
ffs              vfs        builtin    0     -        -
suser            secmodel   builtin    0     -        -
wapbl            vfs        builtin    0     -        -

Well, you get the picture...

pooka 6eb225bba1 Add a rump server which comes with all the drivers currently 
available.  In terms of modules it maps to:

There a bunch of other stuff which doesn't show up as any of the

have the appropriate hardware plugged into my workstation.
