Each respective bit is cleared upon reset of its 506 * corresponding ARC of the TPC engine. 507 * @nic_hw_cap_initialized: This field contains a bit per nic H/W engine. 508 * @active_nic_arc: This field contains a bit per ARC of the NIC engines. 509 * Once an engine arc is initialized, its respective bit is 510 * set. Each respective bit is cleared upon reset of its 511 * corresponding ARC of the NIC engine. 512 * @hw_events: array that holds all H/W events that are defined valid. 513 * @events_stat: array that holds histogram of all received events. 514 * @events_stat_aggregate: same as events_stat but doesn't get cleared on reset. 515 * @num_of_valid_hw_events: used to hold the number of valid H/W events. 516 * @nic_ports: array that holds all NIC ports manage structures. 517 * @nic_macros: array that holds all NIC macro manage structures. 518 * @core_info: core info to be used by the Ethernet driver. 519 * @aux_ops: functions for core <-> aux drivers communication. 520 * @flush_db_fifo: flag to force flush DB FIFO after a write. 521 * @hbm_cfg: HBM subsystem settings 522 * @hw_queues_lock_mutex: used by simulator instead of hw_queues_lock. 523 * @queues_test_info: information used by the driver when testing the HW queues. 524 */ 525 struct gaudi2_device { 526 int (*cpucp_info_get)(struct hl_device *hdev); 527 528 struct user_mapped_block mapped_blocks[NUM_USER_MAPPED_BLOCKS]; 529 int lfsr_rand_seeds[MME_NUM_OF_LFSR_SEEDS]; 530 531 spinlock_t hw_queues_lock; 532 533 void *scratchpad_kernel_address; 534 dma_addr_t scratchpad_bus_address; 535 536 void *virt_msix_db_cpu_addr; 537 dma_addr_t virt_msix_db_dma_addr; 538 539 u64 dram_bar_cur_addr; 540 u64 hw_cap_initialized; 541 u64 active_hw_arc; 542 u64 dec_hw_cap_initialized; 543 u64 tpc_hw_cap_initialized; 544 u64 active_tpc_arc; 545 u64 nic_hw_cap_initialized; 546 u64 active_nic_arc; 547 u32 hw_events[GAUDI2_EVENT_SIZE]; 548 u32 events_stat[GAUDI2_EVENT_SIZE]; 549 u32 events_stat_aggregate[GAUDI2_EVENT_SIZE]; 550 u32 num_of_valid_hw_events; 551 552 /* Queue testing */ 553 struct gaudi2_queues_test_info queues_test_info[GAUDI2_NUM_TESTED_QS]; 554 }; 555 556 /* 557 * Types of the Gaudi2 IP blocks, used by special blocks iterator. 558 * Required for scenarios where only particular block types can be 559 * addressed (e.g., special PLDM images). 560 */ 561 enum gaudi2_block_types { 562 GAUDI2_BLOCK_TYPE_PLL, 563 GAUDI2_BLOCK_TYPE_RTR, 564 GAUDI2_BLOCK_TYPE_CPU, 565 GAUDI2_BLOCK_TYPE_HIF, 566 GAUDI2_BLOCK_TYPE_HBM, 567 GAUDI2_BLOCK_TYPE_NIC, 568 GAUDI2_BLOCK_TYPE_PCIE, 569 GAUDI2_BLOCK_TYPE_PCIE_PMA, 570 GAUDI2_BLOCK_TYPE_PDMA, 571 GAUDI2_BLOCK_TYPE_EDMA, 572 GAUDI2_BLOCK_TYPE_PMMU, 573 GAUDI2_BLOCK_TYPE_PSOC, 574 GAUDI2_BLOCK_TYPE_ROT, 575 GAUDI2_BLOCK_TYPE_ARC_FARM, 576 GAUDI2_BLOCK_TYPE_DEC, 577 GAUDI2_BLOCK_TYPE_MME, 578 GAUDI2_BLOCK_TYPE_EU_BIST, 579 GAUDI2_BLOCK_TYPE_SYNC_MNGR, 580 GAUDI2_BLOCK_TYPE_STLB, 581 GAUDI2_BLOCK_TYPE_TPC, 582 GAUDI2_BLOCK_TYPE_HMMU, 583 GAUDI2_BLOCK_TYPE_SRAM, 584 GAUDI2_BLOCK_TYPE_XBAR, 585 GAUDI2_BLOCK_TYPE_KDMA, 586 GAUDI2_BLOCK_TYPE_XDMA, 587 GAUDI2_BLOCK_TYPE_XFT, 588 GAUDI2_BLOCK_TYPE_MAX 589 }; 590 591 extern const u32 gaudi2_dma_core_blocks_bases[DMA_CORE_ID_SIZE]; 592 extern const u32 gaudi2_qm_blocks_bases[GAUDI2_QUEUE_ID_SIZE]; 593 extern const u32 gaudi2_mme_acc_blocks_bases[MME_ID_SIZE]; 594 extern const u32 gaudi2_mme_ctrl_lo_blocks_bases[MME_ID_SIZE]; 595 extern const u32 edma_stream_base[NUM_OF_EDMA_PER_DCORE * NUM_OF_DCORES]; 596 extern const u32 gaudi2_rot_blocks_bases[ROTATOR_ID_SIZE]; 597 598 void gaudi2_iterate_tpcs(struct hl_device *hdev, struct iterate_module_ctx *ctx); 599 int gaudi2_coresight_init(struct hl_device *hdev); 600 int gaudi2_debug_coresight(struct hl_device *hdev, struct hl_ctx *ctx, void *data); 601 void gaudi2_halt_coresight(struct hl_device *hdev, struct hl_ctx *ctx); 602 void gaudi2_init_blocks(struct hl_device *hdev, struct dup_block_ctx *cfg_ctx); 603 bool gaudi2_is_hmmu_enabled(struct hl_device *hdev, int dcore_id, int hmmu_id); 604 void gaudi2_write_rr_to_all_lbw_rtrs(struct hl_device *hdev, u8 rr_type, u32 rr_index, u64 min_val, 605 u64 max_val); 606 void gaudi2_pb_print_security_errors(struct hl_device *hdev, u32 block_addr, u32 cause, 607 u32 offended_addr); 608 int gaudi2_init_security(struct hl_device *hdev); 609 void gaudi2_ack_protection_bits_errors(struct hl_device *hdev); 610 int gaudi2_send_device_activity(struct hl_device *hdev, bool open); 611 612 #endif /* GAUDI2P_H_ */ 613
