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

+ 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.

+ This is a framebuffer driver for the Conexant cx23415 MPEG
+ encoder/decoder.
+
+ This is used in the Hauppauge PVR-350 card.
+
+ To compile this driver as a module, choose M here: the

+ 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.
