| |
| /** |
| * 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 fat) channel widths; there is no separate |
| * factory measurement for fat 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 subband for the target channel, by |
| * comparing against first and last channels in each subband |
| * (see struct iwl4965_eeprom_calib_subband_info). |
| * |
| * |
| * 4) Linearly interpolate (EEPROM) factory calibration measurement sets, |
| * referencing the 2 factory-measured (sample) channels within the subband. |
| * |
| * 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 subband. 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 versa. |
| * |
| * 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). |

| * |
| * These registers provide handshake between driver and 4965 for the Rx queue |
| * (this queue handles *all* command responses, notifications, Rx data, etc. |
| * sent from 4965 uCode to host driver). Unlike Tx, there is only one Rx |
| * queue, and only one Rx DMA/FIFO channel. Also unlike Tx, which can |
| * concatenate up to 20 DRAM buffers to form a Tx frame, each Receive Buffer |
| * Descriptor (RBD) points to only one Rx Buffer (RB); there is a 1:1 |
| * mapping between RBDs and RBs. |
| * |
| * Driver must allocate host DRAM memory for the following, and set the |
| * physical address of each into 4965 registers: |
| * |
| * 1) Receive Buffer Descriptor (RBD) circular buffer (CB), typically with 256 |
| * entries (although any power of 2, up to 4096, is selectable by driver). |
| * Each entry (1 dword) points to a receive buffer (RB) of consistent size |
| * (typically 4K, although 8K or 16K are also selectable by driver). |
| * Driver sets up RB size and number of RBDs in the CB via Rx config |
| * register FH_MEM_RCSR_CHNL0_CONFIG_REG. |
| * |
| * Bit fields within one RBD: |
| * 27-0: Receive Buffer physical address bits [35:8], 256-byte aligned |
| * |
| * Driver sets physical address [35:8] of base of RBD circular buffer |
| * into FH_RSCSR_CHNL0_RBDCB_BASE_REG [27:0]. |
| * |
| * 2) Rx status buffer, 8 bytes, in which 4965 indicates which Rx Buffers |
| * (RBs) have been filled, via a "write pointer", actually the index of |
| * the RB's corresponding RBD within the circular buffer. Driver sets |
| * physical address [35:4] into FH_RSCSR_CHNL0_STTS_WPTR_REG [31:0]. |
| * |
| * Bit fields in lower dword of Rx status buffer (upper dword not used |
| * by driver; see struct iwl4965_shared, val0): |
| * 31-12: Not used by driver |
| * 11- 0: Index of last filled Rx buffer descriptor |
| * (4965 writes, driver reads this value) |
| * |
| * As the driver prepares Receive Buffers (RBs) for 4965 to fill, driver must |
| * enter pointers to these RBs into contiguous RBD circular buffer entries, |
| * and update the 4965's "write" index register, FH_RSCSR_CHNL0_RBDCB_WPTR_REG. |
| * |
| * This "write" index corresponds to the *next* RBD that the driver will make |
| * available, i.e. one RBD past the tail of the ready-to-fill RBDs within |
| * the circular buffer. This value should initially be 0 (before preparing any |
| * RBs), should be 8 after preparing the first 8 RBs (for example), and must |
| * wrap back to 0 at the end of the circular buffer (but don't wrap before |
| * "read" index has advanced past 1! See below). |
| * NOTE: 4965 EXPECTS THE WRITE INDEX TO BE INCREMENTED IN MULTIPLES OF 8. |
| * |
| * As the 4965 fills RBs (referenced from contiguous RBDs within the circular |
| * buffer), it updates the Rx status buffer in host DRAM, 2) described above, |
| * to tell the driver the index of the latest filled RBD. The driver must |
| * read this "read" index from DRAM after receiving an Rx interrupt from 4965. |
| * |
| * The driver must also internally keep track of a third index, which is the |
| * next RBD to process. When receiving an Rx interrupt, driver should process |
| * all filled but unprocessed RBs up to, but not including, the RB |
| * corresponding to the "read" index. For example, if "read" index becomes "1", |
| * driver may process the RB pointed to by RBD 0. Depending on volume of |
| * traffic, there may be many RBs to process. |
| * |
| * If read index == write index, 4965 thinks there is no room to put new data. |
| * Due to this, the maximum number of filled RBs is 255, instead of 256. To |
| * be safe, make sure that there is a gap of at least 2 RBDs between "write" |
| * and "read" indexes; that is, make sure that there are no more than 254 |
| * buffers waiting to be filled. |
