drm/i915: Increase fb alignment to 64k
An untiled framebuffer must be aligned to 64k. This is normally handled by intel_pin_and_fence_fb_obj(), but the intelfb_create() likes to be different and do the pinning itself. However, it aligns the buffer object incorrectly for pre-i965 chipsets causing a PGTBL_ERR when it is installed onto the output. Fixes: KMS error message while initializing modesetting - render error detected: EIR: 0x10 [i915] http://bugs.freedesktop.org/show_bug.cgi?id=22936 Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: stable@kernel.org Signed-off-by: Eric Anholt <eric@anholt.net>
