Component VIDEO_FB_IVTV_FORCE_PAT

Component Type: kbuild config

Description: force cx23415 framebuffer init with x86 PAT enabled

More info: 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.
