It replaces the older i830 module that 37 supported a subset of the hardware in older X.org releases. 38 39 Note that the older i810/i815 chipsets require the use of the 40 i810 driver instead, and the Atom z5xx series has an entirely 41 different implementation. 42 43 If "M" is selected, the module will be called i915. 44 45config DRM_I915_FORCE_PROBE 46 string "Force probe driver for selected new Intel hardware" 47 depends on DRM_I915 48 help 49 This is the default value for the i915.force_probe module 50 parameter.
