  23          This is a video4linux driver for Conexant cx23416 or cx23415 based
  24          PCI personal video recorder devices.
  25
  26          This is used in devices such as the Hauppauge PVR-150/250/350/500
  27          cards.

  29          To compile this driver as a module, choose M here: the
  30          module will be called ivtv.

  36          Enable the usage of the a DVB set of ioctls that were abused by
  37          IVTV driver for a while.
  38
  39          Those ioctls were not needed for a long time, as IVTV implements
  40          the proper V4L2 ioctls since kernel 3.3.

  49          This driver provides an ALSA interface as another method for user
  50          applications to obtain PCM audio data from Conexant cx23415/cx23416
  51          based PCI TV cards supported by the ivtv driver.
  52
  53          The ALSA interface has much wider use in user applications performing
  54          PCM audio capture, than the V4L2 "/dev/video24" PCM audio interface
  55          provided by the main ivtv driver.

  78        help
  79          With PAT enabled, the cx23415 framebuffer driver does not
  80          utilize write-combined caching on the framebuffer memory.
  81          For this reason, the driver will by default disable itself
  82          when initializied on a kernel with PAT enabled (i.e. not
  83          using the nopat kernel parameter).
  84
  85          The driver is not easily upgradable to the PAT-aware
  86          ioremap_wc() API since the firmware hides the address
  87          ranges that should be marked write-combined from the driver.
  88
  89          With this setting enabled, the framebuffer will initialize on
  90          PAT-enabled systems but the framebuffer memory will be uncached.

  92          If unsure, say N.
