LiteOS2021 6e0a3f10bb 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.

LiteOS2021 dc9ec6856f feat: L0-L1 支持Trace
1.【需求描述】
            L0~L1 支持Trace,提供两种工作模式:在线模式、离线缓存模式, 用于按时间线追踪系统事件,如任务切换、中断、ipc等。
        2.【方案描述】
            L0:
            (1).在内核模块预置静态代码桩
            (2).触发桩后,收集系统上下文信息
            (3).离线模式则写入内存,用户可通过dump导出;
            (4).在线模式通过pipeline对接IDE进行可视化解析和展示;
            L1:
            新增trace字符设备,位于"/dev/trace",通过对设备节点的read\write\ioctl,实现用户态trace;

        BREAKING CHANGE:
        1.新增一系列trace的对外API,位于los_trace.h中.
        LOS_TRACE_EASY简易插桩
        LOS_TRACE标准插桩
        LOS_TraceInit配置Trace缓冲区的地址和大小
        LOS_TraceStart开启事件记录
        LOS_TraceStop停止事件记录
        LOS_TraceRecordDump输出Trace缓冲区数据
        LOS_TraceRecordGet获取Trace缓冲区的首地址
        LOS_TraceReset清除Trace缓冲区中的事件
        LOS_TraceEventMaskSet设置事件掩码,仅记录某些模块的事件
        LOS_TraceHwiFilterHookReg注册过滤特定中断号事件的钩子函数

Guangyao Ma d8263b1e91 fix: mksh compile bug fix
编译框架整改,需要所有交叉编译指定sysroot以及arch相关的编译选项,用来在编译链
接过程中在指定的sysroot路径下,寻找符合arch要求的依赖库。往往,sysroot选项和
arch选项需要同时出现在编译链接选项中。
