/* Nx Console configuration options:
|
|
*
|
|
* CONFIG_NXCONSOLE
|
|
* Enables building of the NxConsole driver.
|
|
*
|
|
* Output text/graphics options:
|
|
*
|
|
* CONFIG_NXCONSOLE_BPP
|
|
* Currently, NxConsole supports only a single pixel depth. This
|
|
* configuration setting must be provided to support that single pixel depth.
|
|
* Default: The smallest enabled pixel depth. (see CONFIG_NX_DISABLE_*BPP)
|
|
* CONFIG_NXCONSOLE_CURSORCHAR
|
|
* The bitmap code to use as the cursor. Default '_'
|
|
* CONFIG_NXCONSOLE_MXCHARS
|
|
* NxConsole needs to remember every character written to the console so
|
|
* that it can redraw the window. This setting determines the size of some
|
|
* internal memory allocations used to hold the character data. Default: 128.
|
|
* CONFIG_NXCONSOLE_CACHESIZE
|
|
* NxConsole 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. (NOTE: There is still
|
|
* inherently a race condition in this!). Unfortunately, the font cache would
|
|
* be quite large if all fonts were saved. The CONFIG_NXCONSOLE_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.
|
|
* CONFIG_NXCONSOLE_LINESEPARATION
|
|
* This the space (in rows) between each row of test. Default: 0
|
|
* CONFIG_NXCONSOLE_NOWRAP
|
|
* By default, lines will wrap when the test reaches the right hand side
|
|
* of the window. This setting can be defining to change this behavior so
|
|
* that the text is simply truncated until a new line is encountered.
|
|
*
|
|
* Input options:
|
|
*
|
|
* CONFIG_NXCONSOLE_NXKBDIN
|
|
* Take input from the NX keyboard input callback. By default, keyboard
|
|
* input is taken from stdin (/dev/console). If this option is set, then
|
|
* the interface nxcon_kbdin() is enabled. That interface may be driven
|
|
* by window callback functions so that keyboard input *only* goes to the
|
|
* top window.
|
|
* CONFIG_NXCONSOLE_KBDBUFSIZE
|
|
* If CONFIG_NXCONSOLE_NXKBDIN is enabled, then this value may be used to
|
|
* define the size of the per-window keyboard input buffer. Default: 16
|
|
* CONFIG_NXCONSOLE_NPOLLWAITERS
|
|
* The number of threads that can be waiting for read data available.
|
|
* Default: 4

* If CONFIG_NXCONSOLE_NXKBDIN is not selected, then the NxConsole will

* receive its input from stdin (/dev/console). This works great but
