nvproxy denies NVIDIA resource-manager classes and control commands it does not already understand, instead of passing them through to the host driver. This PR allowlists two of those: - **AMPERE_B (`0xc797`).** Ampere GA10x allocates this graphics class instead of `AMPERE_A` (`0xc697`, GA100). The parameter blob is the same `NV_GR_ALLOCATION_PARAMETERS` structure. Without the class ID, the sentry logs `handler is undefined for allocation class 0xc797` and `vkCreateDevice` fails. Register it next to `AMPERE_A` under `CapGraphics`, same as `TURING_A`, `ADA_A`, and `HOPPER_A`. Not a video or compute class; no new driver capability. - **`NVB0CC_CTRL_CMD_GET_HS_CREDITS_MAPPING` (`0xb0cc0116`).** Nsight Compute on multi-chiplet GPUs issues this after `GET_CHIPLET_HS_CREDIT_POOL` (`0xb0cc0115`). Without it, the sentry logs `handler is undefined` and NCU fails to prepare the kernel. Register it on the 560.28.03 ABI node under `CapProfiling`, same as the other B0CC profiler commands.
