异常情景的level1 是最底层 show 当前状况的 api其他具体的异常情景会根据 自身情景 调用 这些api
oops 打印 Unable to ... 到 ---[ end trace 行为 如果调用panic,就会做panic的行为,否则只是打印 是什么时候会调用panic 1. panic_on_oops 为 1 2. in_interrupt 2.1 硬中断 2.2 软中断 2.3 NMIpanic 打印 Kernel panic ... 行为 通知感兴趣模块,死机或重启 被谁调用的 只有oops会调用panicBUG !CONFIG_BUG #define BUG() do { } while (1) CONFIG_BUG && !HAVE_ARCH_BUG #define BUG() do { printk("BUG: failure at %s:%d/%s()!\n", __FILE__, __LINE__, __func__); \ barrier_before_unreachable(); \ panic("BUG!"); \ } while (0) CONFIG_BUG && HAVE_ARCH_BUG #define BUG() _BUG(__FILE__, __LINE__, BUG_INSTR_VALUE) #define BUG() _BUG(__FILE__, __LINE__, BUG_INSTR_VALUE) // #define BUG_INSTR_VALUE 0xe7f001f2 // 以这个值为arm的二进制代码执行,会产生未定义指令异常 #define _BUG(file, line, value) __BUG(file, line, value) #define __BUG(__file, __line, __value) \ do { \ asm volatile("1:\t" BUG_INSTR(__value) "\n" \ ".pushsection .rodata.str, \"aMS\", %progbits, 1\n" \ "2:\t.asciz " #__file "\n" \ ".popsection\n" \ ".pushsection __bug_table,\"aw\"\n" \ ".align 2\n" \ "3:\t.word 1b, 2b\n" \ "\t.hword " #__line ", 0\n" \ ".popsection"); \ unreachable(); \ } while (0) BUG_ON #define BUG_ON(condition) do { if (unlikely(condition)) BUG(); } while (0) level2 的话 有很多,level 2 对应了具体的异常情景比如 除0 的函数路径比如 缺页 的函数路径1. 踩内存、硬件Bit位翻转导致的数据异常 一般需要同时编译出来的符号表（vmlinux）进行反汇编分析 Unable to handle kernel paging request at virtual address XXXXXXXXX2. 调用BUG // arm64 BUG 直接调用 panic 代码中出现异常导致调用到BUG()触发的主动重启 Kernel BUG at ffffff8008311ac8 [verbose debug info unavailable]3. oom Out of memory意味着已无可用的memory，这样的问题必然存在一些耗费资源的进程耗尽了memory的资源触发的KE Kernel panic - not syncing: Out of memory and no killable processes...4. 未定义指令异常 一般是CPU/DRAM不稳定导致的问题 Internal error: Oops - undefined instruction5. 卡死导致硬件看门狗超时 多见于底层频繁irq/bus卡死，导致kicker无法被schedule，从而引起watch dog触发中断 引导系统进入FIQ处理流程，最终call到BUG触发重启。 // wathchdog 是 fiq ??? （表现为HWT和Hardware Reboot）6. 软件看门狗超时 MTK平台有hang_detect的机制，system_server进程每30S回去软件喂狗 如果系统卡在超过10min/11min/12min/14min时,会dump出不同的信息用于debug。
