[PATCH 4/4] iwlwifi: split the drivers for agn and legacy devices 3945/4965

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Meenakshi Venkataraman <meenakshi.venkataraman@xxxxxxxxx>

Intel WiFi devices 3945 and 4965 now have their own driver in the folder

	drivers/net/wireless/iwlegacy

Add support to build these drivers independently of the driver for
AGN devices. Selecting the 3945 builds iwl3945.ko and iwl_legacy.ko,
and selecting the 4965 builds iwl4965.ko and iwl_legacy.ko. iwl-legacy.ko
contains code shared between both devices.

The 3945 is an ABG/BG device, with no support for 802.11n. The 4965 is a 2x3
ABGN device.

-  * BSM operation:
-  *
-  * The Bootstrap State Machine (BSM) stores a short bootstrap uCode program
-  * in special SRAM that does not power down during RFKILL.  When powering back
-  * up after power-saving sleeps (or during initial uCode load), the BSM loads
-  * the bootstrap program into the on-board processor, and starts it.
-  *
-  * The bootstrap program loads (via DMA) instructions and data for a new
-  * program from host DRAM locations indicated by the host driver in the
-  * BSM_DRAM_* registers.  Once the new program is loaded, it starts
-  * automatically.
-  *
-  * When initializing the NIC, the host driver points the BSM to the
-  * "initialize" uCode image.  This uCode sets up some internal data, then
-  * notifies host via "initialize alive" that it is complete.
-  *
-  * The host then replaces the BSM_DRAM_* pointer values to point to the
-  * normal runtime uCode instructions and a backup uCode data cache buffer
-  * (filled initially with starting data values for the on-board processor),
-  * then triggers the "initialize" uCode to load and launch the runtime uCode,
-  * which begins normal operation.
-  *
-  * When doing a power-save shutdown, runtime uCode saves data SRAM into
-  * the backup data cache in DRAM before SRAM is powered down.
-  *
-  * When powering back up, the BSM loads the bootstrap program.  This reloads
-  * the runtime uCode instructions and the backup data cache into SRAM,
-  * and re-launches the runtime uCode from where it left off.

- * 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.

- * 4965 txpower calculations rely on information from three sources:

- *     3) statistics notifications
- *
- * EEPROM data consists of:
- *
- * 1)  Regulatory information (max txpower and channel usage flags) is provided
- *     separately for each channel that can possibly supported by 4965.
- *     40 MHz wide (.11n HT40) channels are listed separately from 20 MHz
- *     (legacy) channels.
- *
- *     See struct iwl4965_eeprom_channel for format, and struct iwl4965_eeprom
- *     for locations in EEPROM.
- *
- * 2)  Factory txpower calibration information is provided separately for
- *     sub-bands of contiguous channels.  2.4GHz has just one sub-band,
- *     but 5 GHz has several sub-bands.
- *
- *     In addition, per-band (2.4 and 5 Ghz) saturation txpowers are provided.
- *
- *     See struct iwl4965_eeprom_calib_info (and the tree of structures
- *     contained within it) for format, and struct iwl4965_eeprom for
- *     locations in EEPROM.

-/**
- * 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).

- * Gain tables.
- *
- * The following tables contain pair of values for setting txpower, i.e.
- * gain settings for the output of the device's digital signal processor (DSP),
- * and for the analog gain structure of the transmitter.
- *
- * Each entry in the gain tables represents a step of 1/2 dB.  Note that these
- * are *relative* steps, not indications of absolute output power.  Output
- * power varies with temperature, voltage, and channel frequency, and also
- * requires consideration of average power (to satisfy regulatory constraints),
- * and peak power (to avoid distortion of the output signal).
- *
- * Each entry contains two values:
- * 1)  DSP gain (or sometimes called DSP attenuation).  This is a fine-grained
- *     linear value that multiplies the output of the digital signal processor,
- *     before being sent to the analog radio.
- * 2)  Radio gain.  This sets the analog gain of the radio Tx path.
- *     It is a coarser setting, and behaves in a logarithmic (dB) fashion.
- *
- * EEPROM contains factory calibration data for txpower.  This maps actual
- * measured txpower levels to gain settings in the "well known" tables
- * below ("well-known" means here that both factory calibration *and* the
- * driver work with the same table).
- *
- * There are separate tables for 2.4 GHz and 5 GHz bands.  The 5 GHz table
- * has an extension (into negative indexes), in case the driver needs to
- * boost power setting for high device temperatures (higher than would be
- * present during factory calibration).  A 5 Ghz EEPROM index of "40"
- * corresponds to the 49th entry in the table used by the driver.

- * 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).

- *
- * BSM operation:
- *
- * The Bootstrap State Machine (BSM) stores a short bootstrap uCode program
- * in special SRAM that does not power down during RFKILL.  When powering back
- * up after power-saving sleeps (or during initial uCode load), the BSM loads
- * the bootstrap program into the on-board processor, and starts it.
- *
- * The bootstrap program loads (via DMA) instructions and data for a new
- * program from host DRAM locations indicated by the host driver in the
- * BSM_DRAM_* registers.  Once the new program is loaded, it starts
- * automatically.
- *
- * When initializing the NIC, the host driver points the BSM to the
- * "initialize" uCode image.  This uCode sets up some internal data, then
- * notifies host via "initialize alive" that it is complete.
- *
- * The host then replaces the BSM_DRAM_* pointer values to point to the
- * normal runtime uCode instructions and a backup uCode data cache buffer
- * (filled initially with starting data values for the on-board processor),
- * then triggers the "initialize" uCode to load and launch the runtime uCode,
- * which begins normal operation.
- *
- * When doing a power-save shutdown, runtime uCode saves data SRAM into
- * the backup data cache in DRAM before SRAM is powered down.
- *
- * When powering back up, the BSM loads the bootstrap program.  This reloads
- * the runtime uCode instructions and the backup data cache into SRAM,
- * and re-launches the runtime uCode from where it left off.

-/************************** RX-FUNCTIONS ****************************/
-/*
- * Rx theory of operation
- *
- * The host allocates 32 DMA target addresses and passes the host address
- * to the firmware at register IWL_RFDS_TABLE_LOWER + N * RFD_SIZE where N is
- * 0 to 31
- *
- * Rx Queue Indexes
- * The host/firmware share two index registers for managing the Rx buffers.
- *
- * The READ index maps to the first position that the firmware may be writing
- * to -- the driver can read up to (but not including) this position and get
- * good data.
- * The READ index is managed by the firmware once the card is enabled.
- *
- * The WRITE index maps to the last position the driver has read from -- the
- * position preceding WRITE is the last slot the firmware can place a packet.
- *
- * The queue is empty (no good data) if WRITE = READ - 1, and is full if
- * WRITE = READ.
- *
- * During initialization, the host sets up the READ queue position to the first
- * INDEX position, and WRITE to the last (READ - 1 wrapped)
- *
- * When the firmware places a packet in a buffer, it will advance the READ index
- * and fire the RX interrupt.  The driver can then query the READ index and
- * process as many packets as possible, moving the WRITE index forward as it
- * resets the Rx queue buffers with new memory.
- *
- * The management in the driver is as follows:
- * + A list of pre-allocated SKBs is stored in iwl->rxq->rx_free.  When
