| 168 | * struct iwl_cfg |
| 169 | * @fw_name_pre: Firmware filename prefix. The api version and extension |
| 170 | * (.ucode) will be added to filename before loading from disk. The |
| 171 | * filename is constructed as fw_name_pre<api>.ucode. |
| 172 | * @ucode_api_max: Highest version of uCode API supported by driver. |
| 173 | * @ucode_api_min: Lowest version of uCode API supported by driver. |
| 174 | * |
| 175 | * We enable the driver to be backward compatible wrt API version. The |
| 176 | * driver specifies which APIs it supports (with @ucode_api_max being the |
| 177 | * highest and @ucode_api_min the lowest). Firmware will only be loaded if |
| 178 | * it has a supported API version. The firmware's API version will be |
| 179 | * stored in @iwl_priv, enabling the driver to make runtime changes based |
| 180 | * on firmware version used. |
| 181 | * |
| 182 | * For example, |
| 183 | * if (IWL_UCODE_API(priv->ucode_ver) >= 2) { |
| 184 | * Driver interacts with Firmware API version >= 2. |
| 185 | * } else { |
| 186 | * Driver interacts with Firmware API version 1. |
| 187 | * } |
| 188 | * |
| 189 | * The ideal usage of this infrastructure is to treat a new ucode API |
| 190 | * release as a new hardware revision. That is, through utilizing the |
| 191 | * iwl_hcmd_utils_ops etc. we accommodate different command structures |
| 192 | * and flows between hardware versions (4965/5000) as well as their API |
| 193 | * versions. |
