There's a call to drm_intel_bo_emit_reloc() later in this function that it
looks like you forgot to update. brw->wm.surf_offset needs to change to
binding_table:
/* Emit relocation to surface contents. Section 5.1.1 of the gen4
* bspec ("Data Cache") says that the data cache does not exist as
* a separate cache and is just the sampler cache.
*/
drm_intel_bo_emit_reloc(brw->intel.batch.bo,
(brw->wm.surf_offset[surf_index] +
offsetof(struct gen7_surface_state, ss1)),
bo, 0,
I915_GEM_DOMAIN_SAMPLER, 0);
With that fixed, this patch is:
