Hi Frederic and Chris,
i have just tested the kernel but the patch is not there.
I have downloaded the source wit apt-get source linux-image-
extra-3.5.0-30-generic but the patch has not been included.
int i915_gem_init_aliasing_ppgtt(struct drm_device *dev)
{
struct drm_i915_private *dev_priv = dev->dev_private;
struct i915_hw_ppgtt *ppgtt;
unsigned first_pd_entry_in_global_pt;
int i;
int ret = -ENOMEM;
/* ppgtt PDEs reside in the global gtt pagetable, which has 512*1024
* entries. For aliasing ppgtt support we just steal them at the end for
* now. */
---- first_pd_entry_in_global_pt = 512*1024 - I915_PPGTT_PD_ENTRIES; ----
this line should be there
++++ first_pd_entry_in_global_pt = dev_priv->mm.gtt->gtt_total_entries -
I915_PPGTT_PD_ENTRIES;
