source insight 導入s5qv210源碼

問題：.將內核源碼全部導入source insight導致重複頭文件太多，不能準確定位文件

目標: 只導入相關平臺代碼，減少重複頭文件

 

步驟一:

編譯內核，將輸出保存到build_log.txt

make ARCH=arm > build_log.txt

步驟二：

編輯腳本命名爲sg.sh，複製代碼到腳本文件，如我的開發板  ls arch/arm/mach-s5pv210

ARCH=arm      #arm平臺
MACH=s5pv210  #開發板  

#!/bin/sh
ARCH=arm
MACH=s5pv210
FILE_IN=$1
FILE_OUT=$2
# .c
SOURCE_LIST=""
# generated file list
FILE_LIST=""
# nest depth for function get_includes()
NEST_DTPTH=0
# recursive function, used to get included files from files.
# result is stored in FILE_LIST
# $1 : file list, e.g. "fs/ext4/file.c fs/ext4/fsync.c"
get_includes()
{
        local includes
        local file
        for file in $1
        do
                if [ ! -e ${file} ]; then
                        continue
                fi
                if echo "${FILE_LIST}" | grep -E ${file} > /dev/null; then
                        continue
                fi
                FILE_LIST="${FILE_LIST} ${file}"
                NEST_DTPTH=$((NEST_DTPTH+1))
                echo "<${NEST_DTPTH} : ${file}"
                includes=$(                                                                                \
                        grep -E -H '^#include' ${file} |                                \

get_includes "${SOURCE_LIST}"
FILE_LIST=$(echo "${FILE_LIST}" | sed -r -e 's/\s/\r\n/g' )
echo "${FILE_LIST}" > ${FILE_OUT}

 

步驟三：

執行命令    ./sg.sh build_log.txt file_list.txt   

file_list.txt  將記錄所需頭文件

 

步驟四：

source  insight 導入file_list.txt   

注 將file_list.txt 放在內核根目錄下   sourceinsght 工程也要建在內核根目錄下
