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.
