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.

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
|
|
module will be called ivtv-alsa.

This is a framebuffer driver for the Conexant cx23415 MPEG

|
|
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.
