|
|
|
* @fw_name_pre: Firmware filename prefix. The api version and extension

|

|
|

* filename is constructed as fw_name_pre<api>.ucode.
|
|
|
|
|
* @ucode_api_max: Highest version of uCode API supported by driver.
|

|
|
|
* @ucode_api_min: Lowest version of uCode API supported by driver.
|
2009-08-01 05:28:07 +08:00
|
|
|
* @pa_type: used by 6000 series only to identify the type of Power Amplifier
|
2009-08-14 04:30:54 +08:00
|
|
|
* @max_ll_items: max number of OTP blocks

* @shadow_ram_support: shadow support for OTP memory
|

* @led_compensation: compensate on the led on/off time per HW according

|
* to the deviation to achieve the desired led frequency.
|
|
|
|
|
* The detail algorithm is described in iwl-led.c
|
2009-09-18 01:43:44 +08:00
|

* @use_rts_for_ht: use rts/cts protection for HT traffic
|
2009-09-26 05:24:26 +08:00
|
|
|
* @chain_noise_num_beacons: number of beacons used to compute chain noise
|
2009-10-24 04:42:27 +08:00
|
|
|
* @adv_thermal_throttle: support advance thermal throttle
|
2009-10-24 04:42:28 +08:00
|
|
|
* @support_ct_kill_exit: support ct kill exit condition
|
2009-10-31 05:36:18 +08:00
|
|
|
* @support_wimax_coexist: support wimax/wifi co-exist
|
2010-01-23 06:22:46 +08:00
|
|
|
* @plcp_delta_threshold: plcp error rate threshold used to trigger
|
|
|
|
|
* radio tuning when there is a high receiving plcp error rate
|
2008-12-03 04:14:06 +08:00
|
|
|
*
|
|
|
|
|
* We enable the driver to be backward compatible wrt API version. The
|
|
|
|
|
* driver specifies which APIs it supports (with @ucode_api_max being the
|
|
|
|
|
* highest and @ucode_api_min the lowest). Firmware will only be loaded if
|
|
|
|
|
* it has a supported API version. The firmware's API version will be
|
|
|
|
|
* stored in @iwl_priv, enabling the driver to make runtime changes based
|
|
|
|
|
* on firmware version used.
|
|
|
|
|
*
|
|
|
|
|
* For example,
|
|
|
|
|
* if (IWL_UCODE_API(priv->ucode_ver) >= 2) {
|
|
|
|
|
* Driver interacts with Firmware API version >= 2.
|
|
|
|
|
* } else {
|
|
|
|
|
* Driver interacts with Firmware API version 1.
|
|
|
|
|
* }
|
|
|
|
|
*
|
|
|
|
|
* The ideal usage of this infrastructure is to treat a new ucode API
|
|
|
|
|
* release as a new hardware revision. That is, through utilizing the
|
|
|
|
|
* iwl_hcmd_utils_ops etc. we accommodate different command structures
|
|
|
|
|
* and flows between hardware versions (4965/5000) as well as their API
|
|
|
|
|
* versions.

iwlwifi: reliable entering of critical temperature state
When uCode detects critical temperature it should send "card state
notification" interrupt to driver and then shut itself down to prevent
overheating. There is a race condition where uCode shuts down before it
can deliver the interrupt to driver.
Additional method provided here for driver to enter CT_KILL state based
on temperature reading.
How it works:
Method 1:
If driver receive "card state notification" interrupt from uCode; it
enters "CT_KILL" state immediately
Method 2:
If the last temperature report by Card reach Critical temperature,
driver will send "statistic notification" request to uCode to verify the
temperature reading, if driver can not get reply from uCode within
300ms, driver will enter CT_KILL state automatically.
Method 3:
If the last temperature report by Card did not reach Critical
temperature, but uCode already shut down due to critical temperature.
All the host commands send to uCode will not get process by uCode;
when command queue reach the limit, driver will check the last reported
temperature reading, if it is within pre-defined margin, enter "CT_KILL"
state immediately. In this case, when uCode ready to exit from "CT_KILL" state,
driver need to restart the adapter in order to reset all the queues and
resume normal operation.
One additional issue being address here, when system is in CT_KILL
state, both tx and rx already stopped, but driver still can send host
command to uCode, it will flood the command queue since card was not
responding; adding STATUS_CT_KILL flag to reject enqueue host commands
to uCode if it is in CT_KILL state, when uCode is ready to come out of
CT_KILL, driver will clear the STATUS_CT_KILL bit and allow enqueue the host
commands to uCode to recover from CT_KILL state.

iwlwifi: reliable entering of critical temperature state
When uCode detects critical temperature it should send "card state
notification" interrupt to driver and then shut itself down to prevent
overheating. There is a race condition where uCode shuts down before it
can deliver the interrupt to driver.
Additional method provided here for driver to enter CT_KILL state based
on temperature reading.
How it works:
Method 1:
If driver receive "card state notification" interrupt from uCode; it
enters "CT_KILL" state immediately
Method 2:
If the last temperature report by Card reach Critical temperature,
driver will send "statistic notification" request to uCode to verify the
temperature reading, if driver can not get reply from uCode within
300ms, driver will enter CT_KILL state automatically.
Method 3:
If the last temperature report by Card did not reach Critical
temperature, but uCode already shut down due to critical temperature.
All the host commands send to uCode will not get process by uCode;
when command queue reach the limit, driver will check the last reported
temperature reading, if it is within pre-defined margin, enter "CT_KILL"
state immediately. In this case, when uCode ready to exit from "CT_KILL" state,
driver need to restart the adapter in order to reset all the queues and
resume normal operation.
One additional issue being address here, when system is in CT_KILL
state, both tx and rx already stopped, but driver still can send host
command to uCode, it will flood the command queue since card was not
responding; adding STATUS_CT_KILL flag to reject enqueue host commands
to uCode if it is in CT_KILL state, when uCode is ready to come out of
CT_KILL, driver will clear the STATUS_CT_KILL bit and allow enqueue the host
commands to uCode to recover from CT_KILL state.
