4.4 Adding Log Groups to Firmware Traces

The GPU driver can enable more tracing in the firmware logs through the pvrdebug command. There are various log groups that can be enabled in the firmware, and the required groups are communicated during the debug. To enable more (or less) log groups, the command can be used as follows:

pvrdebug -loggroups main,mts,hwr
