We keep this statement but we want to enable relocations conditionally for Rocketlake and Alderlake 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 Signed-off-by: Zbigniew Kempczyński Cc: Dave Airlie Cc: Daniel Vetter Cc: Jason Ekstrand --- .../gpu/drm/i915/gem/i915_gem_execbuffer.c | 24 +++++++++++++++---- 1 file changed, 19 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 297143511f99..78b86a7bc39a 100644 --- a/drivers/gpu/drm/i915/gem/i915_gem_execbuffer.c +++ b/drivers/gpu/drm/i915/gem/i915_gem_execbuffer.c @@ -491,16 +491,30 @@ 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.
