The L2 cache can filter counters by srcnode or srcunit.
srcnode - group of units
- gpc - SM L1, constant caches, and parts of the 3D pipeline (e.g. rop)
- hub - front end, compute scheduler, copy engines, video accelerators, MMU, display controller, performance monitor, etc.
- fbp - compression unit, ltcfabric, … (rop on older GPUs)
srcunit - individual units
- tex - SM L1TEX unit
- l1 - I need to check but I think this will be 0 for all chips. l1 was used for Fermi and Kepler which had separate L1 and TEX units.
