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
=> "Video For Linux" => "BT848 Video For Linux"
"Device drivers" => "Multimedia devices" => "Digital Video Broadcasting Devices"
=> "DVB for Linux" "DVB Core Support" "Nebula/Pinnacle PCTV/TwinHan PCI Cards"
=> "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
-----------------------
Loading modules:
modprobe bttv
modprobe dvb-bt8xx
Unloading modules:
modprobe -r dvb-bt8xx
modprobe -r bttv
3b) The automatic 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)
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
Then place a line in /etc/modules containing this text:
dvb-bt8xx
3b) TwinHan and Clones
--------------------------
$ 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:
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.
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

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.

config OMAP_RESET_CLOCKS
bool "Reset unused clocks during boot"
depends on ARCH_OMAP
default n
help
Say Y if you want to reset unused clocks during boot.
This option saves power, but assumes all drivers are
using the clock framework. Broken drivers that do not
yet use clock framework may not work with this option.
If you are booting from another operating system, you
probably do not want this option enabled until your
device drivers work properly.
config OMAP_MUX

depends on ARCH_OMAP
default y
help
Pin multiplexing support for OMAP boards. If your bootloader
sets the multiplexing correctly, say N. Otherwise, or if unsure,
say Y.
config OMAP_MUX_DEBUG
bool "Multiplexing debug output"
depends on OMAP_MUX
default n
help
Makes the multiplexing functions print out a lot of debug info.
This is useful if you want to find out the correct values of the
multiplexing registers.
config OMAP_MUX_WARNINGS
bool "Warn about pins the bootloader didn't set up"
depends on OMAP_MUX
default y
help
Choose Y here to warn whenever driver initialization logic needs
to change the pin multiplexing setup. When there are no warnings
printed, it's safe to deselect OMAP_MUX for your product.

Select this option if you want to use the OMAP mpu timer. This
timer provides more intra-tick resolution than the 32KHz timer,
but consumes more power.

help
Select this option if you want to enable the OMAP 32KHz timer.
This timer saves power compared to the OMAP_MPU_TIMER, and has
support for no tick during idle. The 32KHz timer provides less
intra-tick resolution than OMAP_MPU_TIMER. The 32KHz timer is
currently only available for OMAP-16xx.
