| * 4965 temperature calculation. |
| * |
| * The driver must calculate the device temperature before calculating |
| * a txpower setting (amplifier gain is temperature dependent). The |
| * calculation uses 4 measurements, 3 of which (R1, R2, R3) are calibration |
| * values used for the life of the driver, and one of which (R4) is the |
| * real-time temperature indicator. |
| * |
| * uCode provides all 4 values to the driver via the "initialize alive" |
| * notification (see struct iwl4965_init_alive_resp). After the runtime uCode |
| * image loads, uCode updates the R4 value via statistics notifications |
| * (see STATISTICS_NOTIFICATION), which occur after each received beacon |
| * when associated, or can be requested via REPLY_STATISTICS_CMD. |
| * |
| * NOTE: uCode provides the R4 value as a 23-bit signed value. Driver |
| * must sign-extend to 32 bits before applying formula below. |
| * |
| * Formula: |
| * |
| * degrees Kelvin = ((97 * 259 * (R4 - R2) / (R3 - R1)) / 100) + 8 |
| * |
| * NOTE: The basic formula is 259 * (R4-R2) / (R3-R1). The 97/100 is |
| * an additional correction, which should be centered around 0 degrees |
| * Celsius (273 degrees Kelvin). The 8 (3 percent of 273) compensates for |
| * centering the 97/100 correction around 0 degrees K. |
| * |
| * Add 273 to Kelvin value to find degrees Celsius, for comparing current |
| * temperature with factory-measured temperatures when calculating txpower |
| * settings. |
