void _tnl_draw_prims	(	GLcontext *	ctx,
		const struct gl_client_array *	arrays[],
		const struct _mesa_prim *	prim,
		GLuint	nr_prims,
		const struct _mesa_index_buffer *	ib,
		GLuint	min_index,
		GLuint	max_index

void _tnl_InvalidateState	(	GLcontext *	ctx,
		GLuint	new_state
	)

void _tnl_need_projected_coords	(	GLcontext *	ctx,
		GLboolean	mode
	)

Drivers call this function to tell the TCL module whether or not it wants Normalized Device Coords (NDC) computed.

I.e. whether we should "Divide-by-W". Software renders will want that.

void _tnl_program_string	(	GLcontext *	ctx,
		GLenum	target,
		struct gl_program *	program
	)

Called via ctx->Driver.ProgramStringNotify() after a new vertex program string has been parsed.

void _tnl_RasterPos	(	GLcontext *	ctx,
		const GLfloat	vObj[4]
	)

glRasterPos transformation.

Typically called via ctx->Driver.RasterPos(). XXX some of this code (such as viewport xform, clip testing and setting of ctx->Current.Raster* fields) could get lifted up into the main/rasterpos.c code.

Parameters:

vObj

vertex position in object space

void _tnl_vbo_draw_prims	(	GLcontext *	ctx,
		const struct gl_client_array *	arrays[],
		const struct _mesa_prim *	prim,
		GLuint	nr_prims,
		const struct _mesa_index_buffer *	ib,
		GLboolean	index_bounds_valid,
		GLuint	min_index,
		GLuint	max_index
	)

void _tnl_wakeup
