That URL is no longer valid, so either remove references to it or replace it with linuxtv.org. Rather than updating the URL I've just dropped the cx18.rst driver documentation since it was really out of date.

This is a video4linux driver for Conexant cx23416 or cx23415 based
|
|
PCI personal video recorder devices.
|
|
|
|
This is used in devices such as the Hauppauge PVR-150/250/350/500
|
|
cards.
|
|
|
|
To compile this driver as a module, choose M here: the
|
|
module will be called ivtv.

|
Enable the usage of the a DVB set of ioctls that were abused by
|
|
IVTV driver for a while.
|
|
|
|
Those ioctls were not needed for a long time, as IVTV implements
|
|
the proper V4L2 ioctls since kernel 3.3.

If unsure, say N.

help
|
|
This driver provides an ALSA interface as another method for user
|
|
applications to obtain PCM audio data from Conexant cx23415/cx23416
|
|
based PCI TV cards supported by the ivtv driver.
|
|
|
|
The ALSA interface has much wider use in user applications performing
|
|
PCM audio capture, than the V4L2 "/dev/video24" PCM audio interface
|
|
provided by the main ivtv driver.

To compile this driver as a module, choose M here: the

bool "force cx23415 framebuffer init with x86 PAT enabled"

depends on VIDEO_FB_IVTV && X86_PAT
|
|
help
|
|
With PAT enabled, the cx23415 framebuffer driver does not
|
|
utilize write-combined caching on the framebuffer memory.
|
|
For this reason, the driver will by default disable itself
|
|
when initializied on a kernel with PAT enabled (i.e. not
|
|
using the nopat kernel parameter).
|
|
|
|
The driver is not easily upgradable to the PAT-aware
|
|
ioremap_wc() API since the firmware hides the address
|
|
ranges that should be marked write-combined from the driver.
|
|
|
|
With this setting enabled, the framebuffer will initialize on
|
|
PAT-enabled systems but the framebuffer memory will be uncached.
|
|
|
|
If unsure, say N.
