22	  This is a video4linux driver for Conexant cx23416 or cx23415 based
23	  PCI personal video recorder devices.
24
25	  This is used in devices such as the Hauppauge PVR-150/250/350/500
26	  cards. There is a driver homepage at <http://www.ivtvdriver.org>.
27
28	  To compile this driver as a module, choose M here: the
29	  module will be called ivtv.

31config VIDEO_IVTV_DEPRECATED_IOCTLS
32	bool "enable the DVB ioctls abuse on ivtv driver"
33	depends on VIDEO_IVTV
34	default n
35	---help---
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.
41
42	  If unsure, say N.

44config VIDEO_IVTV_ALSA

46	depends on VIDEO_IVTV && SND
47	select SND_PCM
48	---help---
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.
56
57	  To compile this driver as a module, choose M here: the
58	  module will be called ivtv-alsa.

63	select FB_CFB_FILLRECT

65	select FB_CFB_IMAGEBLIT
66	---help---
67	  This is a framebuffer driver for the Conexant cx23415 MPEG
68	  encoder/decoder.
69
70	  This is used in the Hauppauge PVR-350 card. There is a driver
71	  homepage at <http://www.ivtvdriver.org>.
72
73	  To compile this driver as a module, choose M here: the
74	  module will be called ivtvfb.

76config VIDEO_FB_IVTV_FORCE_PAT
77	bool "force cx23415 framebuffer init with x86 PAT enabled"
78	depends on VIDEO_FB_IVTV && X86_PAT
79	default n
80	---help---
81	  With PAT enabled, the cx23415 framebuffer driver does not
82	  utilize write-combined caching on the framebuffer memory.
83	  For this reason, the driver will by default disable itself
84	  when initializied on a kernel with PAT enabled (i.e. not
85	  using the nopat kernel parameter).
86
87	  The driver is not easily upgradable to the PAT-aware
88	  ioremap_wc() API since the firmware hides the address
89	  ranges that should be marked write-combined from the driver.
90
91	  With this setting enabled, the framebuffer will initialize on
92	  PAT-enabled systems but the framebuffer memory will be uncached.
93
94	  If unsure, say N.
