From c060f291c26ac22721a515c78c7a4779f389ff7e Mon Sep 17 00:00:00 2001 From: Nicholas Bishop Date: Thu, 8 Sep 2016 15:55:03 -0400 Subject: [PATCH] i915g: add dma-buf support to i915_drm_buffer_get_handle The implementation of i915_drm_buffer_get_handle now handles DRM_API_HANDLE_TYPE_FD in the same way that intel_winsys_import_handle does, by calling drm_intel_bo_gem_create_from_prime. Tested by successfully running Chrome's ozone_demo [1] with the ozone-gbm backend on an Intel Pineview M machine. Without this change it fails while trying to create a DMA-BUF.
