PlatformRequestHandler: missing !bInit guard on bSystemParamLimitUpdate causes NV_ERR_INVALID_DATA at boot

[Punch-Pain]

Problem

At boot, PlatformRequestHandler fires two NV_ERR_INVALID_DATA assertions:

NVRM: GPU0 nvAssertOkFailedNoLog: Assertion failed: Invalid data passed [NV_ERR_INVALID_DATA] (0x00000025) returned from PlatformRequestHandler failed to get target temp from SBIOS @ platform_request_handler_ctrl.c:2174
NVRM: GPU0 nvAssertOkFailedNoLog: Assertion failed: Invalid data passed [NV_ERR_INVALID_DATA] (0x00000025) returned from PlatformRequestHandler failed to get platform power mode from SBIOS @ platform_request_handler_ctrl.c:2117

These are boot-only cosmetic (runtime works fine), but the root cause is a missing guard in the driver.

Root Cause

In _pfmreqhndlrCallPshareStatus (platform_request_handler_ctrl.c), the bSystemParamLimitUpdate block at line 2467 has no !bInit guard:

// line 2467 — MISSING guard
if (pPfmreqhndlrData->PFMREQHNDLRACPIData.bSystemParamLimitUpdate)
{
    _pfmreqhndlrUpdateTgpuLimit(pPlatformRequestHandler, pGpu);   // line 2473 → 2174 ASSERT
    _pfmreqhndlrUpdatePpmdLimit(pPlatformRequestHandler, pGpu, NV_FALSE);  // line 2482 → 2117 ASSERT
    pPfmreqhndlrData->PFMREQHNDLRACPIData.bSystemParamLimitUpdate = NV_FALSE;
}

Every other block in the same function has a guard:

Line	Block	Guard
2387	EDPpeak	&& !bInit
2442	UserConfigTGP	&& !bInit
2457	PlatformCustomization	(bInit)
2467	bSystemParamLimitUpdate	none

During init, PSHARESTATUS (func 0x20) returns _UPDATE_LIMIT_PENDING. The driver immediately calls _pfmreqhndlrUpdateTgpuLimit and _pfmreqhndlrUpdatePpmdLimit before PSHAREPARAMS (func 0x2A) has initialized the TGPU/PPMD sensor counters. The counters are bSupported=false && !bVolatile, so pfmreqhndlrGetPerfSensorCounterById returns NV_ERR_INVALID_DATA.

The init-time PPMD update at line 1218 (after PSHAREPARAMS) already handles boot-time PPMD initialization correctly. The bSystemParamLimitUpdate block should be deferred to runtime, matching the pattern used by every other block.

Fix

One-line change at platform_request_handler_ctrl.c:2467:

// BEFORE:
if (pPfmreqhndlrData->PFMREQHNDLRACPIData.bSystemParamLimitUpdate)

// AFTER:
if (pPfmreqhndlrData->PFMREQHNDLRACPIData.bSystemParamLimitUpdate && !bInit)

Environment

• Driver: 610.57.04 (open)
• GPU: RTX 5050 Laptop (GB207M, 10DE:2D98)
• Kernel: 7.2.3-1-cachyos
• Platform: Lenovo LOQ 15IRX11

Impact

Boot-only cosmetic. No runtime side effects. The TGPU limit is applied on first runtime PSHARESTATUS with _UPDATE_LIMIT_PENDING. The init-time PPMD update at line 1218 already handles boot-time sensor initialization.
