// There are up to 9 TPCs per GPC in Hopper, and there are 2 LTP uTLBs per TPC.
// Besides, there is one active RGG uTLB per GPC. Each TPC has a number of
// clients that can make requests to its uTLBs: 1xTPCCS, 1xPE, 2xT1. Requests
// from these units are routed as follows to the 2 LTP uTLBs:
//
// -------- ---------
// | T1_0 | -----------------> | uTLB0 |
// -------- ---------
//
// -------- ---------
// | T1_1 | -----------------> | uTLB1 |
// -------- --------> ---------
// | ^
// ------- | |
// | PE | ----------- |
// ------- |
// |
// --------- |
// | TPCCS | -----------------------
// ---------
//
//
// 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
