C++ (Cpp) tegra_bo_create_with_handle Examples

Example #1

File: uapi.c Project: grate-driver/linux

int tegra_uapi_gem_create(struct drm_device *drm, void *data,
			  struct drm_file *file)
{
	struct drm_tegra_gem_create *args = data;
	struct tegra_bo *bo;

	bo = tegra_bo_create_with_handle(file, drm, args->size, args->flags,
					 &args->handle);
	if (IS_ERR(bo))
		return PTR_ERR(bo);

	return 0;
}

Example #2

File: gem.c Project: JaneDu/ath

			 struct drm_mode_create_dumb *args)
{
	unsigned int min_pitch = DIV_ROUND_UP(args->width * args->bpp, 8);
	struct tegra_drm *tegra = drm->dev_private;
	struct tegra_bo *bo;

	args->pitch = round_up(min_pitch, tegra->pitch_align);
	args->size = args->pitch * args->height;

	bo = tegra_bo_create_with_handle(file, drm, args->size, 0,
					 &args->handle);
	if (IS_ERR(bo))
		return PTR_ERR(bo);

	return 0;
}
