mwifiex: device dump support via devcoredump framework
Currently device dump generated in the driver is retrieved
using ethtool set/get dump commands. We will get rid of
ethtool approach and use devcoredump framework.
Device dump can be trigger by
cat /debugfs/mwifiex/mlanX/device_dump
and when the dump operation is completed, data can be read by
cat /sys/class/devcoredump/devcdX/data
We have prepared following script to split device dump data
into multiple files.
[root]# cat mwifiex_split_dump_data.sh
#!/bin/bash
# usage: ./mwifiex_split_dump_data.sh dump_data
fw_dump_data=$1
mem_type="driverinfo ITCM DTCM SQRAM APU CIU ICU MAC"
for name in ${mem_type[@]}
do
sed -n "/Start dump $name/,/End dump/p" $fw_dump_data > tmp.$name.log
if [ ! -s tmp.$name.log ]
then
rm -rf tmp.$name.log
else
#Remove the describle info "Start dump" and "End dump"
sed '1d' tmp.$name.log | sed '$d' > /data/$name.log
if [ -s /data/$name.log ]
then
echo "generate /data/$name.log"
else
sed '1d' tmp.$name.log | sed '$d' > /var/$name.log
echo "generate /var/$name.log"
fi
rm -rf tmp.$name.log
fi
done
