C++ (Cpp) get_hw_format Examples

Example #1

File: nv20_render.c Project: ChillyWillyGuru/RSXGL

static void
nv20_render_set_format(struct gl_context *ctx)
{
	struct nouveau_render_state *render = to_render_state(ctx);
	struct nouveau_channel *chan = context_chan(ctx);
	struct nouveau_grobj *kelvin = context_eng3d(ctx);
	int i, attr, hw_format;

	FOR_EACH_ATTR(render, i, attr) {
		if (attr >= 0) {
			struct nouveau_array *a = &render->attrs[attr];

			hw_format = a->stride << 8 |
				a->fields << 4 |
				get_hw_format(a->type);

		} else {
			/* Unused attribute. */
			hw_format = NV20_3D_VTXBUF_FMT_TYPE_FLOAT;
		}

		BEGIN_RING(chan, kelvin, NV20_3D_VTXBUF_FMT(i), 1);
		OUT_RING(chan, hw_format);
	}
}
