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_ALPHA_SUPPORT 46 bool "Enable alpha quality support for new Intel hardware by default" 47 depends on DRM_I915 48 help 49 This option is deprecated.
