It replaces the older i830 module that 39 supported a subset of the hardware in older X.org releases. 40 41 Note that the older i810/i815 chipsets require the use of the 42 i810 driver instead, and the Atom z5xx series has an entirely 43 different implementation. 44 45 If "M" is selected, the module will be called i915. 46 47config DRM_I915_FORCE_PROBE 48 string "Force probe driver for selected new Intel hardware" 49 depends on DRM_I915 50 help 51 This is the default value for the i915.force_probe module 52 parameter.
