From: Amitkumar Karwar <[email protected]>
Firmware dump feature is added for PCIe based chipsets which can
be used with the help of ethtool commands.
1) Trigger firmware dump operation:
ethtool --set-dump mlan0 0xff
When the operation is completed, udev event will be sent to
trigger external application.
2) Following udev rule can be used to get the data from ethtool:
DRIVER=="mwifiex_pcie", ACTION=="change", RUN+="/sbin/mwifiex_pcie_fw_dump.sh"
mwifiex_pcie_fw_dump.sh: #!/bin/bash
ethtool --set-dump mlan0 0
ethtool --get-dump mlan0
ethtool --get-dump mlan0 data /tmp/ITCM.log
ethtool --set-dump mlan0 1
ethtool --get-dump mlan0
ethtool --get-dump mlan0 data /tmp/DTCM.log
ethtool --set-dump mlan0 2
ethtool --get-dump mlan0
ethtool --get-dump mlan0 data /tmp/SQRAM.log
ethtool --set-dump mlan0 3
ethtool --get-dump mlan0
ethtool --get-dump mlan0 data /tmp/IRAM.log

its response as well as power save events so that we have a

Existing dedicated card_reset work queue is replaced with the
interface specific workqueue pointer provided by mwifiex module.
Also new work flag is added for card reset task.

Firmware dump feature is added for SDIO based chipsets
which can be used with the help of ethtool commands.
1) Trigger firmware dump operation:
ethtool --set-dump mlan0 0xff
When the operation is completed, udev event will be sent to
trigger external application.
2) Following udev rule can be used to get the data from ethtool:
DRIVER=="mwifiex_sdio", ACTION=="change", RUN+="/sbin/mwifiex_sdio_fw_dump.sh"
mwifiex_sdio_fw_dump.sh: #!/bin/bash
ethtool --set-dump mlan0 0
ethtool --get-dump mlan0
ethtool --get-dump mlan0 data /tmp/ITCM.log
ethtool --set-dump mlan0 1
ethtool --get-dump mlan0
ethtool --get-dump mlan0 data /tmp/DTCM.log

1.8.2.3
From: Xinming Hu <[email protected]>
Some SDIO controllers do not support MMC_PM_KEEP_POWER properly.
To test host sleep feature without putting the system into sleep
we need to simulate host sleep configuration & handshake between
driver and firmware using customized parameters.
This patch adds hscfg debugfs item, with which user could change
host sleep parameters for debugging.

Example:
echo "0 20" > rdeeprom : Read 20 bytes of EEPROM data from offset 0
+hscfg
+ This command is used to debug/simulate host sleep feature using
+ different configuration parameters.
+
+ Usage:
+ echo "<condition> [GPIO# [gap]]]" > hscfg
+ cat hscfg
+
+ where the parameters are,
+ <condition>: bit 0 = 1 -- broadcast data
+ bit 1 = 1 -- unicast data
+ bit 2 = 1 -- mac event
+ bit 3 = 1 -- multicast data
+ [GPIO#]: pin number of GPIO used to wakeup the host.
+ GPIO pin# (e.g. 0-7) or 0xff (interface, e.g. SDIO
+ will be used instead).
+ [gap]: the gap in milliseconds between wakeup signal and
+ wakeup event or 0xff for special setting (host
+ acknowledge required) when GPIO is used to wakeup host.
+
+ Examples:
+ echo "-1" > hscfg : Cancel host sleep mode
+ echo "3" > hscfg : Broadcast and unicast data;
+ Use GPIO and gap set previously
+ echo "2 3" > hscfg : Unicast data and GPIO 3;
+ Use gap set previously
+ echo "2 1 160" > hscfg : Unicast data, GPIO 1 and gap 160 ms
+ echo "2 1 0xff" > hscfg : Unicast data, GPIO 1; Wait for host
+ to ack before sending wakeup event
+

This command is used to get the statistics available in the station.
