/**
* 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 idxes 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 ( . 11 n 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 il4965_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 il4965_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
* idx , 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 idx
* ( shown elsewhere ) as a starting point , adjust this idx 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 idx 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 idx ) , 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 idx increased ) by :
*
* ( eeprom - current ) / 7
*
* If the current voltage is lower ( indicator is higher ) than factory
* voltage , gain should be increased ( gain table idx decreased ) by :
*
* 2 * ( current - eeprom ) / 7
*
* If number of idx 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 idxes 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 idx 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 idx :
*
* 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 idx to stay within the table !
*
*
* 11 ) Read gain table entries for DSP and radio gain , place into appropriate
* location ( s ) in command ( struct il4965_txpowertable_cmd ) .

*
* These registers provide handshake between driver and 4965 for the Rx queue
* ( this queue handles * all * command responses , notifications , Rx data , etc .

* 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 4 K , although 8 K or 16 K are also selectable by driver ) .
* Driver sets up RB size and number of RBDs in the CB via Rx config
* register FH49_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 FH49_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 idx of
* the RB ' s corresponding RBD within the circular buffer . Driver sets
* physical address [ 35 : 4 ] into FH49_RSCSR_CHNL0_STTS_WPTR_REG [ 31 : 0 ] .
*
* Bit fields in lower dword of Rx status buffer ( upper dword not used
* by driver ; see struct il4965_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 " idx register ,
* FH49_RSCSR_CHNL0_RBDCB_WPTR_REG .
*
* This " write " idx 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 " idx has advanced past 1 ! See below ) .
* NOTE : 4965 EXPECTS THE WRITE IDX 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 idx of the latest filled RBD . The driver must
* read this " read " idx from DRAM after receiving an Rx interrupt from 4965 .
*
* The driver must also internally keep track of a third idx , 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 " idx . For example , if " read " idx 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 idx = = write idx , 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 " idxes ; that is , make sure that there are no more than 254
* buffers waiting to be filled .
