gr-regs: sample PGRAPH_EXCEPTION/EXCEPTION1/EXCEPTION2 at the dispatch window
The m81 window still shows SEMAPHORE|EXCEPTION pending at QMD activation (the
PM VA mapping did not clear it). NV_PGRAPH_EXCEPTION (0x400108) and its GPC/BE
companions name which subunit raised the exception (FE/MEMFMT/PD/SCC/DS/
SSYNC/MME/SKED/GPC/BE), which discriminates an engine-context-restore fault
from a method/instruction fault.
