help
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. There is a driver homepage at <http://www.ivtvdriver.org>.
To compile this driver as a module, choose M here: the
module will be called ivtv.
config VIDEO_IVTV_DEPRECATED_IOCTLS
bool "enable the DVB ioctls abuse on ivtv driver"
depends on VIDEO_IVTV
help
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.
config VIDEO_IVTV_ALSA
tristate "Conexant cx23415/cx23416 ALSA interface for PCM audio capture"
depends on VIDEO_IVTV && SND
select SND_PCM
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.

help
This is a framebuffer driver for the Conexant cx23415 MPEG
encoder/decoder.
This is used in the Hauppauge PVR-350 card. There is a driver
homepage at <http://www.ivtvdriver.org>.
To compile this driver as a module, choose M here: the
module will be called ivtvfb.
config VIDEO_FB_IVTV_FORCE_PAT
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.
