0023 This is a video4linux driver for Conexant cx23416 or cx23415 based
0024 PCI personal video recorder devices.
0025
0026 This is used in devices such as the Hauppauge PVR-150/250/350/500
0027 cards.
0028
0029 To compile this driver as a module, choose M here: the
0030 module will be called ivtv.

0037 This driver provides an ALSA interface as another method for user
0038 applications to obtain PCM audio data from Conexant cx23415/cx23416
0039 based PCI TV cards supported by the ivtv driver.
0040
0041 The ALSA interface has much wider use in user applications performing
0042 PCM audio capture, than the V4L2 "/dev/video24" PCM audio interface
0043 provided by the main ivtv driver.

0066 help
0067 With PAT enabled, the cx23415 framebuffer driver does not
0068 utilize write-combined caching on the framebuffer memory.
0069 For this reason, the driver will by default disable itself
0070 when initializied on a kernel with PAT enabled (i.e. not
0071 using the nopat kernel parameter).
0072
0073 The driver is not easily upgradable to the PAT-aware
0074 ioremap_wc() API since the firmware hides the address
0075 ranges that should be marked write-combined from the driver.
0076
0077 With this setting enabled, the framebuffer will initialize on
0078 PAT-enabled systems but the framebuffer memory will be uncached.
0079
0080 If unsure, say N.
