We keep this statement but we want to enable relocations conditionally for Alderlake S+P under require_force_probe flag set. Keeping relocations under require_force_probe flag is interim solution until IGTs will be rewritten to use softpin. v2: - remove inline from function definition (Jani) - fix indentation v3: change to GRAPHICS_VER() (Zbigniew) v4: remove RKL from flag as it is already shipped (Rodrigo) Signed-off-by: Zbigniew Kempczyński Cc: Dave Airlie Cc: Daniel Vetter Cc: Jason Ekstrand Cc: Rodrigo Vivi Acked-by: Dave Airlie --- .../gpu/drm/i915/gem/i915_gem_execbuffer.c | 23 +++++++++++++++---- 1 file changed, 18 insertions(+), 5 deletions(-) diff --git a/drivers/gpu/drm/i915/gem/i915_gem_execbuffer.c b/drivers/gpu/drm/i915/gem/i915_gem_execbuffer.c index a8abc9af5ff4..81064914640f 100644 --- a/drivers/gpu/drm/i915/gem/i915_gem_execbuffer.c +++ b/drivers/gpu/drm/i915/gem/i915_gem_execbuffer.c @@ -491,16 +491,29 @@ eb_unreserve_vma(struct eb_vma *ev) ev->flags &= ~__EXEC_OBJECT_RESERVED; } +static bool platform_has_relocs_enabled(const struct i915_execbuffer *eb) +{ + /* + * Relocations are disallowed starting from gen12 with Tigerlake + * as an exception.
