// There are up to 5 TPCs per GPC in Pascal, and there is 1 LTP uTLB per TPC. Besides, there is one RGG uTLB per GPC.
// Each TPC has a number of clients that can make requests to its uTLB: 1xTPCCS, 1xPE, 2xT1. The client ids are local
// to their GPC and the id mapping is linear across TPCs:
// TPC_n has TPCCS_n, PE_n, T1_p, and T1_q, where p=2*n and q=p+1.
//
// NV_PFAULT_CLIENT_GPC_LTP_UTLB_n and NV_PFAULT_CLIENT_GPC_RGG_UTLB enums can be ignored. These will never be reported
// in a fault message, and should never be used in an invalidate. Therefore, we define our own values.
