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. config VIDEO_IVTV_ALSA tristate "Conexant cx23415/cx23416 ALSA interface for PCM audio capture" depends on VIDEO_IVTV && SND select SND_PCM 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. config VIDEO_FB_IVTV tristate "Conexant cx23415 framebuffer support" depends on VIDEO_IVTV && FB select FB_CFB_FILLRECT select FB_CFB_COPYAREA select FB_CFB_IMAGEBLIT help 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 module will be called ivtvfb. config VIDEO_FB_IVTV_FORCE_PAT 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.
