    backends/drm: Import gbm bos using dmabuf · d7ec5199
    Vlad Zahorodnii authored
    It appears that importing gbm_bo's using eglCreateImageKHR() doesn't
    work on nvidia.
    
    Another issue is that Platform::createDmaBufTexture() uses
    gbm_bo_create(). The nvidia driver doesn't like that, it's preferred to
    use gbm_bo_create_with_modifiers().
    
    In order to address those issues, this change refactors how gbm_bo
    objects are imported and how gbm_bo's are allocated for dmabuf textures,
    so the same code can be reused in EglGbmBackend::textureForOutput()
    and Platform::createDmaBufTexture().
