Bluetooth: btmrvl add firmware dump support
This patch adds firmware dump support for marvell bluetooth chipset. Currently only SD8897 is supported. This is implemented based on dev_coredump, a new mechnism introduced in kernel 3.18rc3 Firmware dump can be trigger by echo 1 > /sys/kernel/debug/bluetooth/hci*/config/fw_dump and when the dump operation is completed, data can be read by cat /sys/class/devcoredump/devcd*/data We have prepared following script to divide fw memory dump data into multiple files based on memory type. [root]# cat btmrvl_split_dump_data.sh #!/bin/bash # usage: ./btmrvl_split_dump_data.sh dump_data fw_dump_data=$1 mem_type="ITCM DTCM SQRAM APU CIU ICU MAC EXT7 EXT8 EXT9 EXT10 EXT11 EXT12 EXT13 EXTLAST" 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 Signed-off-by: Xinming Hu <huxm@marvell.com> Signed-off-by: Cathy Luo <cluo@marvell.com> Signed-off-by: Avinash Patil <patila@marvell.com> Reviewed-by: Johannes Berg <johannes@sipsolutions.net> Reviewed-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Amitkumar Karwar <akarwar@marvell.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
