STRUCT IWL_FW_INI_REGION_TLV(9)

💖 struct iwl_fw_ini_region_tlv (9) 💖

okay so bestie, you're in the Kernel API Manual and this page is all about struct iwl_fw_ini_region_tlv — the region TLV. she's giving "configures parameters for region data collection" energy, and we're gonna go through every single field, no skipping, no cap ✨

🌸 NAME 🌸

struct iwl_fw_ini_region_tlv — region TLV 🎀

✨ SYNOPSIS ✨

here's the struct exactly as she appears, bestie:

       struct iwl_fw_ini_region_tlv {
           struct iwl_fw_ini_header hdr;
           __le32 id;
           u8 type;
           u8 sub_type;
           u8 sub_type_ver;
           u8 reserved;
           u8 name[IWL_FW_INI_MAX_NAME];
           union {
             struct iwl_fw_ini_region_dev_addr dev_addr;
             struct iwl_fw_ini_region_dev_addr_range dev_addr_range;
             struct iwl_fw_ini_region_fifos fifos;
             struct iwl_fw_ini_region_err_table err_table;
             struct iwl_fw_ini_region_internal_buffer internal_buffer;
             struct iwl_fw_ini_region_special_device_memory special_mem;
             __le32 dram_alloc_id;
             __le32 tlv_mask;
           };
           __le32 addrs[];
        };

🎀 Members 🎀

okay so the members are giving very specific main-character energy:

• hdr — debug header.
• id — region id. Max id is IWL_FW_INI_MAX_REGION_ID.
• type — region type. One of enum iwl_fw_ini_region_type.
• sub_type — region sub type.
• sub_type_ver — region sub type version.
• reserved — not in use.
• name — region name.
• {unnamed_union} — anonymous. she has no name, but she contains the options below, iykyk.
• dev_addr — device address configuration. Used by IWL_FW_INI_REGION_DEVICE_MEMORY, IWL_FW_INI_REGION_PERIPHERY_MAC, IWL_FW_INI_REGION_PERIPHERY_PHY, IWL_FW_INI_REGION_PERIPHERY_AUX, IWL_FW_INI_REGION_PAGING, IWL_FW_INI_REGION_CSR, IWL_FW_INI_REGION_DRAM_IMR and IWL_FW_INI_REGION_PCI_IOSF_CONFIG, IWL_FW_INI_REGION_DBGI_SRAM, FW_TLV_DEBUG_REGION_TYPE_DBGI_SRAM, IWL_FW_INI_REGION_PERIPHERY_SNPS_DPHYIP.
• dev_addr_range — device address range configuration. Used by IWL_FW_INI_REGION_PERIPHERY_MAC_RANGE and IWL_FW_INI_REGION_PERIPHERY_PHY_RANGE.
• fifos — fifos configuration. Used by IWL_FW_INI_REGION_TXF and IWL_FW_INI_REGION_RXF.
• err_table — error table configuration. Used by IWL_FW_INI_REGION_LMAC_ERROR_TABLE and IWL_FW_INI_REGION_UMAC_ERROR_TABLE.
• internal_buffer — internal monitor buffer configuration. Used by IWL_FW_INI_REGION_INTERNAL_BUFFER.
• special_mem — special device memory region, used by IWL_FW_INI_REGION_SPECIAL_DEVICE_MEMORY.
• dram_alloc_id — dram allocation id. One of enum iwl_fw_ini_allocation_id. Used by IWL_FW_INI_REGION_DRAM_BUFFER.
• tlv_mask — tlv collection mask. Used by IWL_FW_INI_REGION_TLV.
• addrs — array of addresses attached to the end of the region tlv.

🌈 Description 🌈

Configures parameters for region data collection. that's it, that's the description, and she ate 💅
