+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]

+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.

+/* DVB USB compliant linux driver for Conexant USB reference design.
+ *
+ * The Conexant reference design I saw on their website was only for analogue
+ * capturing (using the cx25842). The box I took to write this driver (reverse
+ * engineered) is the one labeled Medion MD95700. In addition to the cx25842
+ * for analogue capturing it also has a cx22702 DVB-T demodulator on the main
+ * board. Besides it has a atiremote (X10) and a USB2.0 hub onboard.
+ *
+ * Maybe it is a little bit premature to call this driver cxusb, but I assume
+ * the USB protocol is identical or at least inherited from the reference
+ * design, so it can be reused for the "analogue-only" device (if it will
+ * appear at all).
+ *
+ * TODO: check if the cx25840-driver (from ivtv) can be used for the analogue
+ * part

+          Support for PCI cards based on the Pluto2 FPGA like the Satelco
+          Easywatch Mobile Terrestrial DVB-T Receiver.
+
+          Since these cards have no MPEG decoder onboard, they transmit
+          only compressed MPEG data over the PCI bus, so you need
+          an external software decoder to watch TV on your computer.
+
+          Say Y or M if you own such a device and want to use it.
