| 260 | * We enable the driver to be backward compatible wrt API version. The |
| 261 | * driver specifies which APIs it supports (with @ucode_api_max being the |
| 262 | * highest and @ucode_api_min the lowest). Firmware will only be loaded if |
| 263 | * it has a supported API version. The firmware's API version will be |
| 264 | * stored in @iwl_priv, enabling the driver to make runtime changes based |
| 265 | * on firmware version used. |
| 266 | * |
| 267 | * For example, |
| 268 | * if (IWL_UCODE_API(priv->ucode_ver) >= 2) { |
| 269 | * Driver interacts with Firmware API version >= 2. |
| 270 | * } else { |
| 271 | * Driver interacts with Firmware API version 1. |
| 272 | * } |
| 273 | * |
| 274 | * The ideal usage of this infrastructure is to treat a new ucode API |
| 275 | * release as a new hardware revision. That is, through utilizing the |
| 276 | * iwl_hcmd_utils_ops etc. we accommodate different command structures |
| 277 | * and flows between hardware versions (4965/5000) as well as their API |
| 278 | * versions. |
