Michał Winiarski a5f0edf63b drm/i915: Avoid writing relocs with addresses in non-canonical form ... According to PRM, some parts of HW require the addresses to be in a canonical form, where bits [63:48] == [47]. Let's convert addresses to canonical form prior to relocating and return converted offsets to userspace. We also need to make sure that userspace is using addresses in canonical form in case of softpin. v2: Whitespace fixup, gen8_canonical_addr description (Chris, Ville) v3: Rebase on top of softpin, fix a hole in relocate_entry, s/expect/require (Chris) v4: Handle softpin in validate_exec_list (Chris) v5: Convert back to canonical form at copy_to_user time (Chris) v6: Don't use struct exec_object2 in place of exec_object v7: Use sign_extend64 for converting to canonical form (Joonas), reject non-canonical and non-page-aligned offset for softpin (Chris) v8: Convert back to non-canonical form in a function, split the test for EXEC_OBJECT_PINNED (Chris) v9: s/canonial/canonical, drop accidental double newline (Chris) Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Michel Thierry <michel.thierry@intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Michał Winiarski <michal.winiarski@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1451409892-13708-1-git-send-email-michal.winiarski@intel.com Testcase: igt/gem_bad_reloc/negative-reloc-blt Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=92699 Cc: drm-intel-fixes@lists.freedesktop.org Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> (cherry picked from commit 934acce3c0) Signed-off-by: Jani Nikula <jani.nikula@intel.com>		2016-01-13 10:41:58 +02:00
