Detailed Description

Data Structure Documentation

struct igsc_device_mbist_ppr_status

Device PPR status structure

Definition at line 1739 of file igsc_lib.h.

Data Fields:

uint32_t mbist_test_status 0 – Pass, Any set bit represents that MBIST on the matching channel has failed

uint32_t num_of_ppr_fuses_used_by_fw Number of PPR fuses used by the firmware

uint32_t num_of_remaining_ppr_fuses Number of remaining PPR fuses

struct igsc_ppr_status

PPR status structure

Definition at line 1748 of file igsc_lib.h.

Data Fields:

uint8_t boot_time_memory_correction_pending 0 - No pending boot time memory correction, 1 - Pending boot time memory correction

struct igsc_device_mbist_ppr_status device_mbist_ppr_status[] Array of PPR statuses per device

uint32_t mbist_completed 0 - Not Applied, Any set bit represents mbist completed

uint32_t num_devices real number of devices in the array (on Xe_HP SDV, PVC <= 8)

uint8_t ppr_mode 0 – PPR enabled, 1 – PPR disabled, 2 – PPR test mode, 3 – PPR auto run on next boot

uint32_t ras_ppr_applied 0 - ppr not applied, 1 - ppr applied, 2 - ppr exhausted

uint8_t reserved

uint8_t test_run_status test status

IFR_TEST_STATUS_PASSED_WITH_RECOVERY: Test passed, recoverable error found and repaired. Subslice swap needed.
IFR_TEST_STATUS_SUBSLICE_FAILURE: Test completed, unrecoverable error found (Subslice failure and no spare Subslice available).
IFR_TEST_STATUS_NON_SUBSLICE_FAILURE: Test completed, unrecoverable error found (non-Subslice failure).
IFR_TEST_STATUS_ERROR: Test error
