Subject: [wireless] iwlwifi update to version from 2.6.26
Message-id: 20080818204819.GE9806@redhat.com
O-Subject: [RHEL5 patch 3/6] iwlwifi update to version from 2.6.26
Bugzilla: 438395
Another monster patch...this one updates the iwlwifi drivers (iwl3945
and iwl4965) to match what was released in 2.6.26, including improved
support for 802.11n features. Support for iwl5x00 is sadly lacking,
requiring bits from 2.6.27 that I have yet to stabilize on a RHEL5
kernel.
BZ438395
Tested by me and some people.redhat.com watchers, with good results.

* REPLY_SCAN_CMD = 0x80 (command)

+ * The hardware scan command is very powerful; the driver can set it up to
+ * maintain (relatively) normal network traffic while doing a scan in the
+ * background. The max_out_time and suspend_time control the ratio of how
+ * long the device stays on an associated network channel ("service channel")
+ * vs. how long it's away from the service channel, tuned to other channels
+ * for scanning.
+ *
+ * max_out_time is the max time off-channel (in usec), and suspend_time
+ * is how long (in "extended beacon" format) that the scan is "suspended"
+ * after returning to the service channel. That is, suspend_time is the
+ * time that we stay on the service channel, doing normal work, between
+ * scan segments. The driver may set these parameters differently to support
+ * scanning when associated vs. not associated, and light vs. heavy traffic
+ * loads when associated.
+ *
+ * After receiving this command, the device's scan engine does the following;
+ *
+ * 1) Sends SCAN_START notification to driver
+ * 2) Checks to see if it has time to do scan for one channel
+ * 3) Sends NULL packet, with power-save (PS) bit set to 1,
+ * to tell AP that we're going off-channel
+ * 4) Tunes to first channel in scan list, does active or passive scan
+ * 5) Sends SCAN_RESULT notification to driver
+ * 6) Checks to see if it has time to do scan on *next* channel in list
+ * 7) Repeats 4-6 until it no longer has time to scan the next channel
+ * before max_out_time expires
+ * 8) Returns to service channel
+ * 9) Sends NULL packet with PS=0 to tell AP that we're back
+ * 10) Stays on service channel until suspend_time expires
+ * 11) Repeats entire process 2-10 until list is complete
+ * 12) Sends SCAN_COMPLETE notification
+ *
+ * For fast, efficient scans, the scan command also has support for staying on
+ * a channel for just a short time, if doing active scanning and getting no
+ * responses to the transmitted probe request. This time is controlled by
+ * quiet_time, and the number of received packets below which a channel is
+ * considered "quiet" is controlled by quiet_plcp_threshold.
+ *
+ * For active scanning on channels that have regulatory restrictions against
+ * blindly transmitting, the scan can listen before transmitting, to make sure
+ * that there is already legitimate activity on the channel. If enough
+ * packets are cleanly received on the channel (controlled by good_CRC_th,
+ * typical value 1), the scan engine starts transmitting probe requests.
+ *
+ * Driver must use separate scan commands for 2.4 vs. 5 GHz bands.
+ *
+ * To avoid uCode errors, see timing restrictions described under
+ * struct iwl3945_scan_channel.

+ * background. The max_out_time and suspend_time control the ratio of how
+ * long the device stays on an associated network channel ("service channel")
+ * vs. how long it's away from the service channel, i.e. tuned to other channels
+ * for scanning.
+ *
+ * max_out_time is the max time off-channel (in usec), and suspend_time
+ * is how long (in "extended beacon" format) that the scan is "suspended"
+ * after returning to the service channel. That is, suspend_time is the
+ * time that we stay on the service channel, doing normal work, between
+ * scan segments. The driver may set these parameters differently to support
+ * scanning when associated vs. not associated, and light vs. heavy traffic
+ * loads when associated.
+ *
+ * After receiving this command, the device's scan engine does the following;
+ *
+ * 1) Sends SCAN_START notification to driver
+ * 2) Checks to see if it has time to do scan for one channel
+ * 3) Sends NULL packet, with power-save (PS) bit set to 1,
+ * to tell AP that we're going off-channel
+ * 4) Tunes to first channel in scan list, does active or passive scan
+ * 5) Sends SCAN_RESULT notification to driver
+ * 6) Checks to see if it has time to do scan on *next* channel in list
+ * 7) Repeats 4-6 until it no longer has time to scan the next channel
+ * before max_out_time expires
+ * 8) Returns to service channel
+ * 9) Sends NULL packet with PS=0 to tell AP that we're back
+ * 10) Stays on service channel until suspend_time expires
+ * 11) Repeats entire process 2-10 until list is complete
+ * 12) Sends SCAN_COMPLETE notification
+ *
+ * For fast, efficient scans, the scan command also has support for staying on
+ * a channel for just a short time, if doing active scanning and getting no
+ * responses to the transmitted probe request. This time is controlled by
+ * quiet_time, and the number of received packets below which a channel is
+ * considered "quiet" is controlled by quiet_plcp_threshold.
+ *
+ * For active scanning on channels that have regulatory restrictions against
+ * blindly transmitting, the scan can listen before transmitting, to make sure
+ * that there is already legitimate activity on the channel. If enough
+ * packets are cleanly received on the channel (controlled by good_CRC_th,
+ * typical value 1), the scan engine starts transmitting probe requests.
+ *
+ * Driver must use separate scan commands for 2.4 vs. 5 GHz bands.
+ *
+ * To avoid uCode errors, see timing restrictions described under
+ * struct iwl4965_scan_channel.

+ * 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.

+/************************** EEPROM BANDS ****************************
+ *
+ * The iwl_eeprom_band definitions below provide the mapping from the
+ * EEPROM contents to the specific channel number supported for each
+ * band.
+ *
+ * For example, iwl_priv->eeprom.band_3_channels[4] from the band_3
+ * definition below maps to physical channel 42 in the 5.2GHz spectrum.
+ * The specific geography and calibration information for that channel
+ * is contained in the eeprom map itself.
+ *
+ * During init, we copy the eeprom information and channel map
+ * information into priv->channel_info_24/52 and priv->channel_map_24/52
+ *
+ * channel_map_24/52 provides the index in the channel_info array for a
+ * given channel. We have to have two separate maps as there is channel
+ * overlap with the 2.4GHz and 5.2GHz spectrum as seen in band_1 and
+ * band_2
+ *
+ * A value of 0xff stored in the channel_map indicates that the channel
+ * is not supported by the hardware at all.
+ *
+ * A value of 0xfe in the channel_map indicates that the channel is not
+ * valid for Tx with the current hardware. This means that
+ * while the system can tune and receive on a given channel, it may not
+ * be able to associate or transmit any frames on that
+ * channel. There is no corresponding channel information for that
+ * entry.

-/************************** EEPROM BANDS ****************************
- *
- * The iwl4965_eeprom_band definitions below provide the mapping from the
- * EEPROM contents to the specific channel number supported for each
- * band.
- *
- * For example, iwl4965_priv->eeprom.band_3_channels[4] from the band_3
- * definition below maps to physical channel 42 in the 5.2GHz spectrum.
- * The specific geography and calibration information for that channel
- * is contained in the eeprom map itself.
- *
- * During init, we copy the eeprom information and channel map
- * information into priv->channel_info_24/52 and priv->channel_map_24/52
- *
- * channel_map_24/52 provides the index in the channel_info array for a
- * given channel. We have to have two separate maps as there is channel
- * overlap with the 2.4GHz and 5.2GHz spectrum as seen in band_1 and
- * band_2
- *
- * A value of 0xff stored in the channel_map indicates that the channel
- * is not supported by the hardware at all.
- *
- * A value of 0xfe in the channel_map indicates that the channel is not
- * valid for Tx with the current hardware. This means that
- * while the system can tune and receive on a given channel, it may not
- * be able to associate or transmit any frames on that
- * channel. There is no corresponding channel information for that
- * entry.

- * 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.
