| /** |
| * To calculate a txpower setting for a given desired target txpower, channel, |
| * modulation bit rate, and transmitter chain (4965 has 2 transmitters to |
| * support MIMO and transmit diversity), driver must do the following: |
| * |
| * 1) Compare desired txpower vs. (EEPROM) regulatory limit for this channel. |
| * Do not exceed regulatory limit; reduce target txpower if necessary. |
| * |
| * If setting up txpowers for MIMO rates (rate indexes 8-15, 24-31), |
| * 2 transmitters will be used simultaneously; driver must reduce the |
| * regulatory limit by 3 dB (half-power) for each transmitter, so the |
| * combined total output of the 2 transmitters is within regulatory limits. |
| * |
| * |
| * 2) Compare target txpower vs. (EEPROM) saturation txpower *reduced by |
| * backoff for this bit rate*. Do not exceed (saturation - backoff[rate]); |
| * reduce target txpower if necessary. |
| * |
| * Backoff values below are in 1/2 dB units (equivalent to steps in |
| * txpower gain tables): |
| * |
| * OFDM 6 - 36 MBit: 10 steps (5 dB) |
| * OFDM 48 MBit: 15 steps (7.5 dB) |
| * OFDM 54 MBit: 17 steps (8.5 dB) |
| * OFDM 60 MBit: 20 steps (10 dB) |
| * CCK all rates: 10 steps (5 dB) |
| * |
| * Backoff values apply to saturation txpower on a per-transmitter basis; |
| * when using MIMO (2 transmitters), each transmitter uses the same |
| * saturation level provided in EEPROM, and the same backoff values; |
| * no reduction (such as with regulatory txpower limits) is required. |
| * |
| * Saturation and Backoff values apply equally to 20 Mhz (legacy) channel |
| * widths and 40 Mhz (.11n HT40) channel widths; there is no separate |
| * factory measurement for ht40 channels. |
| * |
| * The result of this step is the final target txpower. The rest of |
| * the steps figure out the proper settings for the device to achieve |
| * that target txpower. |
| * |
| * |
| * 3) Determine (EEPROM) calibration sub band for the target channel, by |
| * comparing against first and last channels in each sub band |
| * (see struct iwl4965_eeprom_calib_subband_info). |
| * |
| * |
| * 4) Linearly interpolate (EEPROM) factory calibration measurement sets, |
| * referencing the 2 factory-measured (sample) channels within the sub band. |
| * |
| * Interpolation is based on difference between target channel's frequency |
| * and the sample channels' frequencies. Since channel numbers are based |
| * on frequency (5 MHz between each channel number), this is equivalent |
| * to interpolating based on channel number differences. |
| * |
| * Note that the sample channels may or may not be the channels at the |
| * edges of the sub band. The target channel may be "outside" of the |
| * span of the sampled channels. |
| * |
| * Driver may choose the pair (for 2 Tx chains) of measurements (see |
| * struct iwl4965_eeprom_calib_ch_info) for which the actual measured |
| * txpower comes closest to the desired txpower. Usually, though, |
| * the middle set of measurements is closest to the regulatory limits, |
| * and is therefore a good choice for all txpower calculations (this |
| * assumes that high accuracy is needed for maximizing legal txpower, |
| * while lower txpower configurations do not need as much accuracy). |
| * |
| * Driver should interpolate both members of the chosen measurement pair, |
| * i.e. for both Tx chains (radio transmitters), unless the driver knows |
| * that only one of the chains will be used (e.g. only one tx antenna |
| * connected, but this should be unusual). The rate scaling algorithm |
| * switches antennas to find best performance, so both Tx chains will |
| * be used (although only one at a time) even for non-MIMO transmissions. |
| * |
| * Driver should interpolate factory values for temperature, gain table |
| * index, and actual power. The power amplifier detector values are |
| * not used by the driver. |
| * |
| * Sanity check: If the target channel happens to be one of the sample |
| * channels, the results should agree with the sample channel's |
| * measurements! |
| * |
| * |
| * 5) Find difference between desired txpower and (interpolated) |
| * factory-measured txpower. Using (interpolated) factory gain table index |
| * (shown elsewhere) as a starting point, adjust this index lower to |
| * increase txpower, or higher to decrease txpower, until the target |
| * txpower is reached. Each step in the gain table is 1/2 dB. |
| * |
| * For example, if factory measured txpower is 16 dBm, and target txpower |
| * is 13 dBm, add 6 steps to the factory gain index to reduce txpower |
| * by 3 dB. |
| * |
| * |
| * 6) Find difference between current device temperature and (interpolated) |
| * factory-measured temperature for sub-band. Factory values are in |
| * degrees Celsius. To calculate current temperature, see comments for |
| * "4965 temperature calculation". |
| * |
| * If current temperature is higher than factory temperature, driver must |
| * increase gain (lower gain table index), and vice verse. |
| * |
| * Temperature affects gain differently for different channels: |
| * |
| * 2.4 GHz all channels: 3.5 degrees per half-dB step |
| * 5 GHz channels 34-43: 4.5 degrees per half-dB step |
| * 5 GHz channels >= 44: 4.0 degrees per half-dB step |
| * |
| * NOTE: Temperature can increase rapidly when transmitting, especially |
| * with heavy traffic at high txpowers. Driver should update |
| * temperature calculations often under these conditions to |
| * maintain strong txpower in the face of rising temperature. |
| * |
| * |
| * 7) Find difference between current power supply voltage indicator |
| * (from "initialize alive") and factory-measured power supply voltage |
| * indicator (EEPROM). |
| * |
| * If the current voltage is higher (indicator is lower) than factory |
| * voltage, gain should be reduced (gain table index increased) by: |
| * |
| * (eeprom - current) / 7 |
| * |
| * If the current voltage is lower (indicator is higher) than factory |
| * voltage, gain should be increased (gain table index decreased) by: |
| * |
| * 2 * (current - eeprom) / 7 |
| * |
| * If number of index steps in either direction turns out to be > 2, |
| * something is wrong ... just use 0. |
| * |
| * NOTE: Voltage compensation is independent of band/channel. |
| * |
| * NOTE: "Initialize" uCode measures current voltage, which is assumed |
| * to be constant after this initial measurement. Voltage |
| * compensation for txpower (number of steps in gain table) |
| * may be calculated once and used until the next uCode bootload. |
| * |
| * |
| * 8) If setting up txpowers for MIMO rates (rate indexes 8-15, 24-31), |
| * adjust txpower for each transmitter chain, so txpower is balanced |
| * between the two chains. There are 5 pairs of tx_atten[group][chain] |
| * values in "initialize alive", one pair for each of 5 channel ranges: |
| * |
| * Group 0: 5 GHz channel 34-43 |
| * Group 1: 5 GHz channel 44-70 |
| * Group 2: 5 GHz channel 71-124 |
| * Group 3: 5 GHz channel 125-200 |
| * Group 4: 2.4 GHz all channels |
| * |
| * Add the tx_atten[group][chain] value to the index for the target chain. |
| * The values are signed, but are in pairs of 0 and a non-negative number, |
| * so as to reduce gain (if necessary) of the "hotter" channel. This |
| * avoids any need to double-check for regulatory compliance after |
| * this step. |
| * |
| * |
| * 9) If setting up for a CCK rate, lower the gain by adding a CCK compensation |
| * value to the index: |
| * |
| * Hardware rev B: 9 steps (4.5 dB) |
| * Hardware rev C: 5 steps (2.5 dB) |
| * |
| * Hardware rev for 4965 can be determined by reading CSR_HW_REV_WA_REG, |
| * bits [3:2], 1 = B, 2 = C. |
| * |
| * NOTE: This compensation is in addition to any saturation backoff that |
| * might have been applied in an earlier step. |
| * |
| * |
| * 10) Select the gain table, based on band (2.4 vs 5 GHz). |
| * |
| * Limit the adjusted index to stay within the table! |
| * |
| * |
| * 11) Read gain table entries for DSP and radio gain, place into appropriate |
| * location(s) in command (struct iwl4965_txpowertable_cmd). |

| * controller (uCode) are via the command queue (one of the Tx queues). All |
| * uCode command responses/replies/notifications, including Rx frames, are |
| * conveyed from uCode to driver via the Rx queue. |

| * allocating this memory, the driver must make sure that data written by |
| * the host CPU updates DRAM immediately (and does not get "stuck" in CPU's |
| * cache memory), so DRAM and cache are consistent, and the device can |
| * immediately see changes made by the driver. |
| * |
| * 4965 supports up to 16 DRAM-based Tx queues, and services these queues via |
| * up to 7 DMA channels (FIFOs). Each Tx queue is supported by a circular array |
| * in DRAM containing 256 Transmit Frame Descriptors (TFDs). |
