If you are using a Technotrend/Hauppauge DVB-C card *without* analog
module, you might have to use module parameter adac=-1 (dvb-ttpci.o).
5. The dvb_net device doesn't give me any multicast packets
5. The dvb_net device doesn't give me any packets at all
Run tcpdump on the dvb0_0 interface. This sets the interface
into promiscous mode so it accepts any packets from the PID
you have configured with the dvbnet utility. Check if there
are any packets with the IP addr and MAC addr you have
configured with ifconfig.
If tcpdump doesn't give you any output, check the statistics
which ifconfig outputs. (Note: If the MAC address is wrong,
dvb_net won't get any input; thus you have to run tcpdump
before checking the statistics.) If there are no packets at
all then maybe the PID is wrong. If there are error packets,
then either the PID is wrong or the stream does not conform to
the MPE standard (EN 301 192, http://www.etsi.org/). You can
use e.g. dvbsnoop for debugging.
6. The dvb_net device doesn't give me any multicast packets
Check your routes if they include the multicast address range.
Additionally make sure that "source validation by reversed path
lookup" is disabled:
$ "echo 0 > /proc/sys/net/ipv4/conf/dvb0/rp_filter"

For a dvb-ttpci av7110 based full-featured card the following
modules are loaded:

gives you access to the "analog" tv picture of the av7110 mpeg2
decoder.
- v4l2-common: common functions for Video4Linux-2 drivers
- v4l1-compat: backward compatiblity layer for Video4Linux-1 legacy
applications
- dvb-core: DVB core module. This provides you with the
/dev/dvb/adapter entries
- saa7146: SAA7146 core driver. This is need to access any SAA7146
based card in your system.
- saa7146_vv: SAA7146 video and vbi functions. These are only needed
for full-featured cards.
- video-buf: capture helper module for the saa7146_vv driver. This
one is responsible to handle capture buffers.

Macintosh HFS Filesystem for Linux
==================================
HFS stands for ``Hierarchical File System'' and is the filesystem used
by the Mac Plus and all later Macintosh models. Earlier Macintosh
models used MFS (``Macintosh File System''), which is not supported,
MacOS 8.1 and newer support a filesystem called HFS+ that's similar to
HFS but is extended in various areas. Use the hfsplus filesystem driver
to access such filesystems from Linux.
Mount options
=============
When mounting an HFS filesystem, the following options are accepted:
creator=cccc, type=cccc
Specifies the creator/type values as shown by the MacOS finder
used for creating new files. Default values: '????'.
uid=n, gid=n
Specifies the user/group that owns all files on the filesystems.
Default: user/group id of the mounting process.
dir_umask=n, file_umask=n, umask=n
Specifies the umask used for all files , all directories or all
files and directories. Defaults to the umask of the mounting process.
session=n
Select the CDROM session to mount as HFS filesystem. Defaults to
leaving that decision to the CDROM driver. This option will fail
with anything but a CDROM as underlying devices.
part=n
Select partition number n from the devices. Does only makes
sense for CDROMS because they can't be partitioned under Linux.
For disk devices the generic partition parsing code does this
for us. Defaults to not parsing the partition table at all.
quiet
Ignore invalid mount options instead of complaining.
Writing to HFS Filesystems
==========================
HFS is not a UNIX filesystem, thus it does not have the usual features you'd
expect:
o You can't modify the set-uid, set-gid, sticky or executable bits or the uid
and gid of files.
o You can't create hard- or symlinks, device files, sockets or FIFOs.
HFS does on the other have the concepts of multiple forks per file. These
non-standard forks are represented as hidden additional files in the normal
filesystems namespace which is kind of a cludge and makes the semantics for
the a little strange:
o You can't create, delete or rename resource forks of files or the
Finder's metadata.
o They are however created (with default values), deleted and renamed
along with the corresponding data fork or directory.
o Copying files to a different filesystem will loose those attributes
that are essential for MacOS to work.
Creating HFS filesystems
===================================
The hfsutils package from Robert Leslie contains a program called
hformat that can be used to create HFS filesystem. See
<http://www.mars.org/home/rob/proj/hfs/> for details.

Please note, that unlike /proc/chpids in 2.4, the channel path objects reflect
only the logical state and not the physical state, since we cannot track the
latter consistently due to lacking machine support (we don't need to be aware
of anyway).

Piping 'on' or 'off' sets the chpid logically online/offline.
Piping 'on' to an online chpid triggers path reprobing for all devices
the chpid connects to. This can be used to force the kernel to re-use
a channel path the user knows to be online, but the machine hasn't
created a machine check for.

help
Select this option, if you want to enable the kernel interface
to reduce the memory size of the system. This is accomplished
by allocating pages of memory and put them "on hold". This only
makes sense for a system running under VM where the unused pages
will be reused by VM for other guest systems. The interface
allows an external monitor to balance memory of many systems.
Everybody who wants to run Linux under VM should select this
option.

This provides a kernel interface for creating and updating z/VM APPLDATA

intervals, once the timer is started.
Writing 1 or 0 to /proc/appldata/timer starts(1) or stops(0) the timer,
i.e. enables or disables monitoring on the Linux side.
A custom interval value (in seconds) can be written to
/proc/appldata/interval.

APPLDATA monitor record, i.e. enables or disables monitoring this record
