- NvCmdList:
- Added 'offset' parameter: start of the cmdlist within the buffer
- Added nvCmdListReset for resetting a cmdlist (offset/num_cmds cleared)
- NvGpfifo:
- nvGpfifoCreate: disabled fence wait
- nvGpfifoSubmit -> nvGpfifoSubmitCmdList:
- Added fence_incr parameter
- Cleaned up flags and gpfifo entry creation
- Now advances cmdlist offset by the number of cmds submitted
instead of going back to the beginning
