Re: How to kick off a accelerate draw operation in source code

   The "Subsequent" functions kick off the operations.  You'll
have to refer to your hardware documentation for how to do that
for your hardware.

How to kick off a accelerate draw operation in source code

2003-10-09 Thread xiao john 
Hi all,

I am writing a customerized graphic card driver in xfree86,
and I refered to NV dirver, I can find that NVSetupForSolidLine and 
NVSubsequentSolidHorVertLine
.. functions to manipulate the HW register,
I wonder that it is just filling some data in the registers, I want to know 
when and which 
instruction kick off the draw operation.

Please give me some clue.
