feat: L0-L1 支持Perf
...
1.【需求描述】:
L0-L1 支持Perf,提供2种模式的配置, 及3大类型的事件配置:
2种模式:计数模式(仅统计事件发生次数)、采样模式(收集上下文如任务ID、pc、backtrace等)。
3种事件类型:CPU硬件事件(cycle、branch、icache、dcache等)、OS软件事件(task switch、mux pend、irq等)、高精度周期事件(cpu clock)。
2.【方案描述】:
L0:
基于事件采样原理,以性能事件为基础,当事件发生时,相应的事件计数器溢出发生中断,在中断处理函数中记录事件信息,包括当前的pc、当前运 行的任务ID以及调用栈等信息。
L1:
新增perf字符设备,位于“dev/perf”,通过对设备节点的read\ioctl,实现用户态perf
BREAKING CHANGE:
1.新增一系列perf的对外API,位于los_perf.h中.
LOS_PerfInit配置采样数据缓冲区
LOS_PerfStart开启Perf采样
LOS_PerfStop停止Perf采样
LOS_PerfConfig配置Perf采样事件
LOS_PerfDataRead读取采样数据
LOS_PerfNotifyHookReg 注册采样数据缓冲区的钩子函数
LOS_PerfFlushHookReg 注册缓冲区刷cache的钩子
2. 用户态新增perf命令
【Usage】:
./perf [start] /[start id] Start perf.
./perf [stop] Stop perf.
./perf [read nBytes] Read nBytes raw data from perf buffer and print out.
./perf [list] List events to be used in -e.
./perf [stat] or [record] <option> <command>
-e, event selector. use './perf list' to list available events.
-p, event period.
-o, perf data output filename.
-t, taskId filter(whiltelist), if not set perf will sample all tasks.
-s, type of data to sample defined in PerfSampleType los_perf.h.
-P, processId filter(whiltelist), if not set perf will sample all processes.
-d, whether to prescaler (once every 64 counts), which only take effect on cpu cycle hardware event.

fix: init进程收到子进程退出信号后,调用fork重新拉起进程,会导致系统卡死
...
问题原因:init进程执行信号时,线程栈底预留了部分空间给信号上下文使用,
从而导致处理信号时线程栈底比线程控制块里面记录的大,这样在fork的过程中内核
从init线程栈底copy线程上下文给新进程时,copy的不是实际运行的栈底,以致于
新进程的线程上下文不对,在实际运行时跑飞,引发系统卡死。
解决方案:在fork过程copy线程上下文时,判断是否预留了信号上下文空间,如果预留
了,则copy的栈底要基于预留后的栈底去copy线程上下文。

fix: 解决kill进程时无法保证进程的已持有的内核资源合理释放.
...
背景: 当前信号实现原理是在系统调用结束和中断结束时检查是否有信号处理,
如果有信号处理就切去处理信号,信号处理结束后回来继续按原来流程执行。
问题:当用户态线程在执行系统调用或缺页异常时,运行在内核态,如果此时有信
号需要处理,且该线程已经持有了部分内核资源(如:锁,内存等), 此时如
果有中断发生,则在中断结束时,就会去处理该信号,此时用户态线程持有
了内核未释放的资源跑到了用户态去运行,如果该线程在用户态出现问题,
那么它持有的内核资源就无法被释放了。
方案:用户态线程在执行系统调用和缺页异常时暂时屏蔽信号,防止此时有中断去
处理信号,等系统调用结束或缺页异常结束时再去处理信号。
解决的问题:
1. 执行系统调用或缺页异常时屏蔽信号,防止中断去处理信号
2.解决无法kill 因为用户态的锁、ipc等阻塞的用户态线程
3.进程退出方式转变为: 依次通过kill去杀死该进程的所有线程
