Kernel configuration
To use i915 on this platform you need to set CONFIG_DRM_I915_PRELIMINARY_HW_SUPPORT Created attachment 111949 [details]
config-3.19-rc2-Eywa
This is the same result with CONFIG_DRM_I915_PRELIMINARY_HW_SUPPORT=y
The dmesg is required if you want to show that you are actually using the i915.ko. (In reply to Chris Wilson from comment #5) > The dmesg is required if you want to show that you are actually using the > i915.ko. Preferably with drm.debug=14 too. |
