Sometimes we can see the register snapshot without using the intel-gpu-tools. For example: in UMS mode we often get the register snapshot several times in starting X.
It will be good that we expose the raw register values and then they are parsed by intel-gpu-tools if we need to extend the decode. How about adding two debugfs I/F? One is to dump the raw register snapshot(without decode and format). Another is what I have done in the patch. What format should be used when dumping the raw register values? >register name: register value Thanks. > ------------------------------------------------------------------------------ OpenSolaris 2009.06 is a cutting edge operating system for enterprises looking to deploy the next generation of Solaris that includes the latest innovations from Sun and the OpenSource community.
