Ampere GA10x uses class 0xc797 (AMPERE_B) rather than AMPERE_A (0xc697, GA100). vkCreateDevice fails with "handler is undefined for allocation class 0xc797" until this class is proxied with the same NV_GR_ALLOCATION_PARAMETERS as AMPERE_A. Assisted-by: Cursor

Nsight Compute on multi-chiplet GPUs issues 0xb0cc0116 after GET_CHIPLET_HS_CREDIT_POOL. Without this allowlist 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. Assisted-by: Cursor

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 ofAMPERE_A(0xc697, GA100). The parameter blob is the sameNV_GR_ALLOCATION_PARAMETERSstructure. Without the class ID, the sentry logshandler is undefined for allocation class 0xc797andvkCreateDevicefails. Register it next toAMPERE_AunderCapGraphics, same asTURING_A,ADA_A, andHOPPER_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 afterGET_CHIPLET_HS_CREDIT_POOL(0xb0cc0115). Without it, the sentry logshandler is undefinedand NCU fails to prepare the kernel. Register it on the 560.28.03 ABI node underCapProfiling, same as the other B0CC profiler commands.Assisted-by: Cursor
