<li>
<code>CONFIG_NX_MULTIUSER</code>
Configures NX in multi-user mode
</li>
<li>
<code>CONFIG_NX_NPLANES</code>
Some YUV color formats requires support for multiple planes,
one for each color component. Unless you have such special

NX supports a variety of pixel depths. You can save some
memory by disabling support for unused color depths.

<li>
<code>CONFIG_NXGL_PACKEDMSFIRST</code>
If a pixel depth of less than 8-bits is used, then NX needs
to know if the pixels pack from the MS to LS or from LS to MS

<code>CONFIG_NX_BLOCKING</code>
Open the client message queues in blocking mode. In this case,
<code>nx_eventhandler()</code> will never return.
</li>
<li>
<code>CONFIG_NX_MXSERVERMSGS</code> and <code>CONFIG_NX_MXCLIENTMSGS</code>
Specifies the maximum number of messages that can fit in
the message queues. No additional resources are allocated, but
this can be set to prevent flooding of the client or server with
too many messages (<code>CONFIG_PREALLOC_MQ_MSGS</code> controls how many
messages are pre-allocated).

Status: Open
Priority: Medium-low
Description: If CONFIG_NXGRAPHICS is enabled, the build fails the first time
saying that there is "No rule to make target..." for one of the
auto-generated graphics files. This is a nuisance, but if you
simply build again (with the source files already auto-generated)
the problem does not reoccur.
Status: Open
Priority: Low, the work-around is simple
