/*
 * DF-1272 trigger note — tonga VBIOS vdd_dep_on_sclk->count Sclk_voltageOffset overflow.
 *
 * Bug (sys/dev/drm/amd/powerplay/smumgr/tonga_smumgr.c:1620
 *      tonga_populate_clock_stretcher_data_table):
 *   uint8_t i;
 *   for (i = 0; i < sclk_table->count; i++) {           // sclk_table=vdd_dep_on_sclk
 *       ...
 *       smu_data->smc_state_table.Sclk_voltageOffset[i] = volt_offset;  // sized [8]
 *   }
 *   smu72_discrete.h:344  Sclk_voltageOffset[8]
 *   sclk_table->count from VBIOS ucNumEntries (u8 1-255; only !=0 check at parse).
 *   i >= 8 -> overflow into ClockStretcherDataTable / CKS_LOOKUPTable / past
 *   DpmTable into the tonga_smumgr power_tune_defaults pointer.
 *   Gated by PHM_PlatformCaps_ClockStretcher capability.
 *
 * Reachability on the audit guest:
 *   amdgpu.ko module-only (NOT in base kernel); runs only on AMD Tonga HW whose
 *   VBIOS enables clock stretching.  QEMU guest has no AMD GPU; amdgpu.ko not
 *   loaded.  Not triggerable here; latent on real Tonga hardware.
 *
 * Documentation/no-trigger PoC.  See VERDICT.md + fix.diff.
