== SMC Errors ==
These errors are generated by the [[SMC|System Management Controller]].
 
=== 0001 ===
ANA_V12P0_PWRGD is driven high by the [[ANA]] (later [[HANA]]) as long as the [[Power Rails#V_12P0|V_12P0]] rail is within tolerance. If V_12P0 ever drops out of tolerance, the signal is de-asserted, causing the SMC to enter [[Error Codes#EC_FATAL|EC_FATAL]] and the 0001 code to be displayed on the front panel.

VREG_CPU_PWRGD is driven high by the [[CPU]] power controller as long as the [[Power Rails#V_CPUCORE|V_CPUCORE]] rail is within tolerance. If V_CPUCORE ever drops out of tolerance, the signal is de-asserted, causing the SMC to enter [[Error Codes#EC_FATAL|EC_FATAL]] and the 0002 code to be displayed on the front panel.

VREG_GPU_PWRGD is driven high by the [[GPU]] power controller as long as the [[Power Rails#V_GPUCORE|V_GPUCORE]] rail is within tolerance. If V_GPUCORE ever drops out of tolerance, the signal is de-asserted, causing the SMC to enter [[Error Codes#EC_FATAL|EC_FATAL]] and the 0003 code to be displayed on the front panel.

The [[SMC]] communicates with the [[ANA]]/[[HANA]] via the SMBus. If communication is lost, the SMC enters [[Error Codes#EC_FATAL|EC_FATAL]] and the 0010 code is displayed on the front panel.

|}
 
After [[GPU]] power and clocking are available, the [[SMC]] starts [[SMC#seqUnReset|seqUnReset]] which releases the GPU from reset. It then waits for the GPU to assert GPU_RST_DONE. If the GPU_RST_DONE signal is not asserted in the time allotted, [[Error Codes#EC_BOOT|EC_BOOT]] will be reported. The SMC will retry 4 more times. If on the final attempt, GPU_RST_DONE is still not asserted, the SMC remains in EC_BOOT and the 0020 code is displayed on the front panel.

After receiving GPU_RST_DONE during [[SMC#seqUnReset|seqUnReset]], the [[SMC]] monitors the [[PCIe]] L0 status and waits for the link to enter the L0 state. If the link does not enter the L0 state in the time allotted, [[Error Codes#EC_BOOT|EC_BOOT]] will be reported. The SMC will retry 4 more times. The SMC will retry 4 more times. If on the final attempt, the link still does not enter L0 state, the SMC remains in EC_BOOT and the 0021 code is displayed on the front panel.

|}
 
After the [[PCIe]] link has entered the L0 state during [[SMC#seqUnReset|seqUnReset]], the SMC releases the [[CPU]] from reset. The CPU will run the [[Bootloaders]] and start the [[XSS]]. When the XSS starts, it will attempt to retrieve the power up cause from the SMC. If the SMC does not receive GetPowerUpCause in the time allotted, [[Error Codes#EC_BOOT|EC_BOOT]] will be reported. The SMC will retry 4 more times. If on the final attempt, GetPowerUpCause is still not received, the SMC remains in EC_BOOT and the 0022 code is displayed on the front panel.
