From 9843877d10700d6b64b615e0e8724fc9f6ff6268 Mon Sep 17 00:00:00 2001 From: Ben Widawsky Date: Wed, 31 Jul 2013 17:00:12 -0700 Subject: [PATCH] drm/i915: turn bound_ggtt checks to bound_any In some places, we want to know if an object is bound in any address space, and not just the global GTT. This often applies when there is a single global resource (object, pages, etc.) function | reason -------------------------------------------------- i915_gem_object_is_inactive | global object i915_gem_object_put_pages | object's pages 915_gem_object_unpin | global object i915_gem_execbuffer_unreserve_object | temporary until we plumb vma pread/pwrite | see the note below Note: set_to_gtt_domain in pwrite/pread is abused as a wait_rendering call - but that once only worked if the object is bound. We really should replace this with a plain wait_rendering call, which would have the upside that in pread it would be clearer that we actually only wait for oustanding gpu writes.
