191 | * struct iwl_cfg | |
192 | * @fw_name_pre: Firmware filename prefix. The api version and extension | |
193 | * (.ucode) will be added to filename before loading from disk. The | |
194 | * filename is constructed as fw_name_pre<api>.ucode. | |
195 | * @ucode_api_max: Highest version of uCode API supported by driver. | |
196 | * @ucode_api_min: Lowest version of uCode API supported by driver. | |
197 | * | |
198 | * We enable the driver to be backward compatible wrt API version. The | |
199 | * driver specifies which APIs it supports (with @ucode_api_max being the | |
200 | * highest and @ucode_api_min the lowest). Firmware will only be loaded if | |
201 | * it has a supported API version. The firmware's API version will be | |
202 | * stored in @iwl_priv, enabling the driver to make runtime changes based | |
203 | * on firmware version used. | |
204 | * | |
205 | * For example, | |
206 | * if (IWL_UCODE_API(priv->ucode_ver) >= 2) { | |
207 | * Driver interacts with Firmware API version >= 2. | |
208 | * } else { | |
209 | * Driver interacts with Firmware API version 1. | |
210 | * } | |
211 | * | |
212 | * The ideal usage of this infrastructure is to treat a new ucode API | |
213 | * release as a new hardware revision. That is, through utilizing the | |
214 | * iwl_hcmd_utils_ops etc. we accommodate different command structures | |
215 | * and flows between hardware versions (4965/5000) as well as their API | |
216 | * versions. | |
