config NX_NPLANES

config NX_BGCOLOR

config NX_UPDATE
	bool "Display update hooks"
	default n
	---help---
		Enable a callout to inform some external module that the display has
		been updated.  This would be useful in a couple for cases.

		- When a serial LCD is used, but a framebuffer is used to access the
		  LCD.  In this case, the update callout can be used to refresh the
		  affected region of the display.

		- When VNC is enabled.  This is case, this callout is necessary to
		  update the remote frame buffer to match the local framebuffer.

		When this feature is enabled, some external logic must provide this
		interface:

		  void nx_notify_rectangle(FAR NX_PLANEINFOTYPE *pinfo,
		                           FAR const struct nxgl_rect_s *rect);

		That is the function that will handle the notification.  It
		receives the rectangular region that was updated in the provided
		plane.

config NXTERM_CACHESIZE
	int "Font Cache Size"
	default 16
	---help---
		NxTerm supports caching of rendered fonts. This font caching is required
		for two reasons: (1) First, it improves text performance, but more
		importantly (2) it preserves the font memory. Since the NX server runs on
		a separate server thread, it requires that the rendered font memory persist
		until the server has a chance to render the font. Unfortunately, the font
		cache would be quite large if all fonts were saved. The NXTERM_CACHESIZE
		setting will control the size of the font cache (in number of glyphs). Only that
		number of the most recently used glyphs will be retained. Default: 16.
		NOTE: There can still be a race condition between the NxTerm driver and the
		NX task.  If you every see character corruption (especially when printing
		a lot of data or scrolling), then increasing the value of NXTERM_CACHESIZE
		is something that you should try.  Alternatively, you can reduce the size of
		MQ_MAXMSGSIZE which will force NxTerm task to pace the server task.
		NXTERM_CACHESIZE should be larger than MQ_MAXMSGSIZE in any event.
