Are there some people on this list who know a bit about driver
programming.
I'm blocked with de development of the vnc video driver.
Working:
-driver pass all changed regions to the winvnc-server (shared user
kernel memory)
-no more polling mode needed
We get a accurate update, but vnc is NOT faster, to many little updates
gives a protocol overhead.
Have to be done:
-The slowest part is the bitblt (vncserver).
+ How to pass the bitmaps (as shared memory ) to the vncserver?
+ The video driver gives the bitmaps a caching number. This number
can be used to prevent sending the same bimap again.
