---help---
|
|
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. Unfortunately, the font
|
|
cache would be quite large if all fonts were saved. The 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.
|
|
NOTE: There can still be a race condition between the NxConsole 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 NXCONSOLE_CACHESIZE
|
|
is something that you should try. Alternatively, you can reduce the size of
|
|
MQ_MAXMSGSIZE which will force NxConsole task to pace the server task.
|
|
NXCONSOLE_CACHESIZE should be larger than MQ_MAXMSGSIZE in any event.
