While poking around with FBC, I noticed that we don't currently have
stolen memory support for gen2. This series aims to fix that.
I also tried to add support for 830M local memory. Now, I don't actually
know if there are systems out there equipped with local memory or not. But
if they do exist, I wouldn't mind getting one...
As I only have a single gen2 system (855GM), this has only received limited
testing.
Ville Syrjälä (8):
x86: Add vfunc for Intel graphics stolen memory base address
x86: Add Intel graphics stolen memory quirk for gen2 platforms
intel-gtt: Return whether we have local memory or not
intel-gtt: Assume last 128KB of stolen contains the GTT entries on gen2
intel-gtt: Use i810_write_entry() on gen2 platforms
drm/i915: Add I915_CACHE_LOCAL to indicate local memory
drm/i915: Keep track if we have local memory
drm/i915: Determine the stolen memory base address on gen2
