Many people said that the efficiency of the NanoX is not high enough.
They said the functions which draw lines and polygon can be optimized.
But I don't know how to improve it. Can somebody tell me how, and show
me some source code.
adding driver-level linedraw, clipping, and blit code has sped up my
25MHz target significantly. there were also some speedups made for text
draw which were merged into the tree a few years back.
I've put a tarball of the our branch at
http://frye.com/~aaron/microwin-frye-nanosteve.1.tar.bz2 .
I have been working on merging with CVS and porting our local hacks
(including fast linedraw) to other framebuffer devices. I'm almost
there except stipples and dashlists are still broken.
Thanks for your sharing. I've downloaded your tarball, and will study
the source code that you changed.
I heard someboye said that the function "src/nanox/srvclip2.c:
GsSetClipWindow()" can be speed up, do you
know about this?
