This is used in the Hauppauge PVR-350 card. There is a driver
homepage at <http://www.ivtvdriver.org>.
- In order to use this module, you will need to boot with PAT disabled
- on x86 systems, using the nopat kernel parameter.

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
+ default n
+ ---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.
