It replaces the older i830 module that 42 supported a subset of the hardware in older X.org releases. 43 44 Note that the older i810/i815 chipsets require the use of the 45 i810 driver instead, and the Atom z5xx series has an entirely 46 different implementation. 47 48 If "M" is selected, the module will be called i915. 49 50config DRM_I915_FORCE_PROBE 51 string "Force probe driver for selected new Intel hardware" 52 depends on DRM_I915 53 help 54 This is the default value for the i915.force_probe module 55 parameter.
