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

37	  This driver provides an ALSA interface as another method for user
38	  applications to obtain PCM audio data from Conexant cx23415/cx23416
39	  based PCI TV cards supported by the ivtv driver.
40
41	  The ALSA interface has much wider use in user applications performing
42	  PCM audio capture, than the V4L2 "/dev/video24" PCM audio interface
43	  provided by the main ivtv driver.

66	help
67	  With PAT enabled, the cx23415 framebuffer driver does not
68	  utilize write-combined caching on the framebuffer memory.
69	  For this reason, the driver will by default disable itself
70	  when initializied on a kernel with PAT enabled (i.e. not
71	  using the nopat kernel parameter).
72
73	  The driver is not easily upgradable to the PAT-aware
74	  ioremap_wc() API since the firmware hides the address
75	  ranges that should be marked write-combined from the driver.
76
77	  With this setting enabled, the framebuffer will initialize on
78	  PAT-enabled systems but the framebuffer memory will be uncached.
79
80	  If unsure, say N.
