[Intel-gfx] [PATCH 0/6] drm/i915: Gen2 stolen/local memory support (v2)

[ville.syrjala at linux.intel.com]

Another attempt at figuring out stolen memory for gen2. This time instead
of trusting the GTT base address, I used the same method the BIOS uses.
(TOM-TSEG_SIZE-stolen_size). Except on 865G where things are more complicated.
Fortunately it seems to have a simlple answer for us in the for om the TOUD
register.

So far this has only been tested on my 855 laptop with 512MB memory.

Ville Syrjälä (6):
      x86: Add vfunc for Intel graphics stolen memory base address
      x86: Add Intel graphics stolen memory quirk for gen2 platforms
      x86: Print the Intel graphcis stolen memory range
      intel-gtt: Report stolen_size as 0 when local memory is present
      drm/i915: Don't clobber the GTT when it's within stolen memory
      drm/i915: Determine the stolen memory base address on gen2
