Should be the previous patch (9/11: Release vma when the handle is closed) that hooks in gem_object_close to mark each vma as closed if it is owned by the file. http://patchwork.freedesktop.org/patch/68086/ > >diff --git a/drivers/gpu/drm/i915/i915_gem_context.c > >b/drivers/gpu/drm/i915/i915_gem_context.c > >index c4a8a64cd1b2..9669547c7c2d 100644 > >--- a/drivers/gpu/drm/i915/i915_gem_context.c > >+++ b/drivers/gpu/drm/i915/i915_gem_context.c > >@@ -153,6 +153,7 @@ void i915_gem_context_free(struct kref *ctx_ref) > > struct intel_context *ctx = container_of(ctx_ref, typeof(*ctx), ref); > > > > trace_i915_context_free(ctx); > >+ RQ_BUG_ON(!ctx->closed); > > Normal BUG_ON I think.

The comment was cut'n'paste. I don't think it is entirely apt to be talking about the object level active reference here anyway. But I didn't feel inclined to write something that was even more confusing. -Chris -- Chris Wilson, Intel Open Source Technology Centre _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/intel-gfx
