1. How to use?

1.1. Firmware

Most of the USB drivers need to download a firmware to start working.

for USB1.1 (AN2135) you need: dvb-usb-dibusb-5.0.0.11.fw

for USB2.0 HanfTek: dvb-usb-umt-010-02.fw

for USB2.0 DiBcom: dvb-usb-dibusb-6.0.0.8.fw

for USB2.0 AVerMedia AverTV DVB-T USB2: dvb-usb-avertv-a800-01.fw

for USB2.0 TwinhanDTV Alpha/MagicBox II: dvb-usb-vp7045-01.fw

The files can be found on http://www.linuxtv.org/download/firmware/ .

Most of the USB drivers need to download a firmware to the device before start

working.

We do not have the permission (yet) to publish the following firmware-files.

You'll need to extract them from the windows drivers.

Have a look at the Wikipage for the DVB-USB-drivers to find out, which firmware

you need for your device:

You should be able to use "get_dvb_firmware dvb-usb" to get the firmware:

for USB1.1 (AN2235) (a few Artec T1 devices): dvb-usb-dibusb-an2235-01.fw

for USB2.0 Hauppauge: dvb-usb-nova-t-usb2-01.fw

for USB2.0 ADSTech/Kworld USB2.0: dvb-usb-adstech-usb2-01.fw

How to get the Nebula, PCTV and Twinhan DST cards working

=========================================================

How to get the Nebula Electronics DigiTV, Pinnacle PCTV Sat, Twinhan DST + clones working

=========================================================================================

This class of cards has a bt878a as the PCI interface, and

require the bttv driver.

1) General information

======================

Please pay close attention to the warning about the bttv module

options below for the DST card.

This class of cards has a bt878a chip as the PCI interface.

The different card drivers require the bttv driver to provide the means

to access the i2c bus and the gpio pins of the bt8xx chipset.

1) General informations

=======================

2) Compilation rules for Kernel >= 2.6.12

=========================================

These drivers require the bttv driver to provide the means to access

the i2c bus and the gpio pins of the bt8xx chipset.

Enable the following options:

Because of this, you need to enable

"Device drivers" => "Multimedia devices"

 => "Video For Linux" => "BT848 Video For Linux"

Furthermore you need to enable

"Device drivers" => "Multimedia devices" => "Digital Video Broadcasting Devices"

 => "DVB for Linux" "DVB Core Support" "Nebula/Pinnacle PCTV/TwinHan PCI Cards"

2) Loading Modules

==================

3) Loading Modules, described by two approaches

===============================================

In general you need to load the bttv driver, which will handle the gpio and

i2c communication for us, plus the common dvb-bt8xx device driver.

The frontends for Nebula (nxt6000), Pinnacle PCTV (cx24110) and

TwinHan (dst) are loaded automatically by the dvb-bt8xx device driver.

i2c communication for us, plus the common dvb-bt8xx device driver,

which is called the backend.

The frontends for Nebula DigiTV (nxt6000), Pinnacle PCTV Sat (cx24110),

TwinHan DST + clones (dst and dst-ca) are loaded automatically by the backend.

For further details about TwinHan DST + clones see /Documentation/dvb/ci.txt.

3a) Nebula / Pinnacle PCTV

--------------------------

3a) The manual approach

-----------------------

   $ modprobe bttv (normally bttv is being loaded automatically by kmod)

   $ modprobe dvb-bt8xx (or just place dvb-bt8xx in /etc/modules for automatic loading)

Loading modules:

modprobe bttv

modprobe dvb-bt8xx

Unloading modules:

modprobe -r dvb-bt8xx

modprobe -r bttv

3b) TwinHan and Clones

3b) The automatic approach

--------------------------

   $ modprobe bttv i2c_hw=1 card=0x71

   $ modprobe dvb-bt8xx

   $ modprobe dst

The value 0x71 will override the PCI type detection for dvb-bt8xx,

which is necessary for TwinHan cards.

If you're having an older card (blue color circuit) and card=0x71 locks

your machine, try using 0x68, too. If that does not work, ask on the

mailing list.

The DST module takes a couple of useful parameters:

If not already done by installation, place a line either in

/etc/modules.conf or in /etc/modprobe.conf containing this text:

alias char-major-81	bttv

a. verbose takes values 0 to 5. These values control the verbosity level.

b. debug takes values 0 and 1. You can either disable or enable debugging.

c. dst_addons takes values 0 and 0x20:

- A value of 0 means it is a FTA card.

- A value of 0x20 means it has a Conditional Access slot.

Then place a line in /etc/modules containing this text:

dvb-bt8xx

The autodetected values are determined by the "response string"

of the card, which you can see in your logs:

e.g.: dst_get_device_id: Recognize [DSTMCI]

Reboot your system and have fun!

What:	PCMCIA control ioctl (needed for pcmcia-cs [cardmgr, cardctl])

When:	November 2005

Files:	drivers/pcmcia/: pcmcia_ioctl.c

Why:	With the 16-bit PCMCIA subsystem now behaving (almost) like a

	normal hotpluggable bus, and with it using the default kernel

	infrastructure (hotplug, driver core, sysfs) keeping the PCMCIA

	control ioctl needed by cardmgr and cardctl from pcmcia-cs is

	unnecessary, and makes further cleanups and integration of the

	PCMCIA subsystem into the Linux kernel device driver model more

	difficult. The features provided by cardmgr and cardctl are either

	handled by the kernel itself now or are available in the new

	pcmciautils package available at

	http://kernel.org/pub/linux/utils/kernel/pcmcia/

USERSPACE VERBS ACCESS

  The ib_uverbs module, built by enabling CONFIG_INFINIBAND_USER_VERBS,

  enables direct userspace access to IB hardware via "verbs," as

  described in chapter 11 of the InfiniBand Architecture Specification.

  To use the verbs, the libibverbs library, available from

  <http://openib.org/>, is required.  libibverbs contains a

  device-independent API for using the ib_uverbs interface.

  libibverbs also requires appropriate device-dependent kernel and

  userspace driver for your InfiniBand hardware.  For example, to use

  a Mellanox HCA, you will need the ib_mthca kernel module and the

  libmthca userspace driver be installed.

User-kernel communication

  Userspace communicates with the kernel for slow path, resource

  management operations via the /dev/infiniband/uverbsN character

  devices.  Fast path operations are typically performed by writing

  directly to hardware registers mmap()ed into userspace, with no

  system call or context switch into the kernel.

  Commands are sent to the kernel via write()s on these device files.

  The ABI is defined in drivers/infiniband/include/ib_user_verbs.h.

  The structs for commands that require a response from the kernel

  contain a 64-bit field used to pass a pointer to an output buffer.

  Status is returned to userspace as the return value of the write()

  system call.

Resource management

  Since creation and destruction of all IB resources is done by

  commands passed through a file descriptor, the kernel can keep track

  of which resources are attached to a given userspace context.  The

  ib_uverbs module maintains idr tables that are used to translate

  between kernel pointers and opaque userspace handles, so that kernel

  pointers are never exposed to userspace and userspace cannot trick

  the kernel into following a bogus pointer.

  This also allows the kernel to clean up when a process exits and

  prevent one process from touching another process's resources.

Memory pinning

  Direct userspace I/O requires that memory regions that are potential

  I/O targets be kept resident at the same physical address.  The

  ib_uverbs module manages pinning and unpinning memory regions via

  get_user_pages() and put_page() calls.  It also accounts for the

  amount of memory pinned in the process's locked_vm, and checks that

  unprivileged processes do not exceed their RLIMIT_MEMLOCK limit.

  Pages that are pinned multiple times are counted each time they are

  pinned, so the value of locked_vm may be an overestimate of the

  number of pages pinned by a process.

/dev files

  To create the appropriate character device files automatically with

  udev, a rule like

    KERNEL="uverbs*", NAME="infiniband/%k"

  can be used.  This will create device nodes named

    /dev/infiniband/uverbs0

  and so on.  Since the InfiniBand userspace verbs should be safe for

  use by non-privileged processes, it may be useful to add an

  appropriate MODE or GROUP to the udev rule.

	maxcpus=	[SMP] Maximum number of processors that	an SMP kernel

			should make use of

	max_addr=[KMG]	[KNL,BOOT,ia64] All physical memory greater than or

			equal to this physical address is ignored.

	max_luns=	[SCSI] Maximum number of LUNs to probe

			Should be between 1 and 2^32-1.
