[Intel-gfx] [PATCH 2/7] drm/i915: Reuse the reservation_ww_class for acquiring vma backing storage
Chris Wilson
chris at chris-wilson.co.uk
Mon Jun 22 09:59:16 UTC 2020
i915_vma_pin() remains as a convenience function to grab a single range
of address space on the GPU, and must not only acquire the backing
storage of the associated buffer/pages, but must also acquire backing
storage for teh page directory. As such, it will want to receive the
allocations, but in the meantime, convert the custom vma->pages_mutex to
reuse the reservation_ww_class from the associated backing store (object
for now).
