Linux加載vmlinux調試

使用gdb加載內核符號表
arm-eabi-gdb out/target/product/msm8625/obj/KERNEL_OBJ/vmlinux
在內核的.config里面要打開 DEBUG_INFO和DEBUG_VM
定位故障代碼
(gdb) l * qrd7627a_add_io_devices+0x100
0xc07cd05c is in qrd7627a_add_io_devices (/home/yejialong/GH700C/kernel/arch/arm/mach-msm/msm8x25/goso-msm7627a-io.c:1851).
1846 } else if (machine_is_msm8625q_skud() || machine_is_msm8625q_evbd()) {
1847 #ifndef CONFIG_CALA02
1848 platform_device_register(&pmic_mpp_leds_pdev_skud);
1849 #endif
1850 /* enable the skud flash and torch by gpio leds driver */
1851 platform_device_register(&gpio_flash_skud);
1852 } else if (machine_is_msm8625q_skue()) {
1853 /* enable the skue flashlight by gpio leds driver */
1854 platform_device_register(&gpio_flash_skue);
1855 }
下面是mtk平臺加載的方法，但是不管哪個平臺都是差不多的，道理都是一樣的。

rockchip rk3399調試vmlinux

RK平臺tombstone調試
./prebuilts/gcc/linux-x86/arm/arm-eabi-4.8/bin/arm-eabi-addr2line -e ./out/target/product/rk3399_mid/symbols/system/lib/libspeexresampler.so 0x00002d54 /proc/self/cwd/external/speex/libspeex/resample.c:376
arm-eabi-gdb 先用命令找到這個東西，然后在去找去找到vmlinux 還有就是我arm-eabi-4.7/ 這個版本才可以用，這個是我試出來的。
