openharmony_ci 5bed688ca6 !731 【请求检视】fix: 修复LOSCFG_FS_FAT_CACHE宏关闭后编译失败的BUG 
Merge pull request !731 from Far/master
 2021-12-13 10:03:58 +00:00
Far 63e71feca0 fix: 修复LOSCFG_FS_FAT_CACHE宏关闭后编译失败的BUG 
1. 在必要处增加宏开关关闭部分代码的编译；
2. 由于驱动是一个独立的内核线程，在一些场景下文件系统会将用户态地址透传给驱动，这会导致内核崩溃。
因此在需要透传用户态地址时增加了一个内核buffer作为中转。

openharmony_ci 2c33cfce86 !599 feat: L0~L1 支持Perf

 2021-09-29 06:15:02 +00:00
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.

SimonLi f7d010dfa4 fix(mtd): 去除mtd对hisilicon驱动的依赖 
【背景】
1. liteos-a内核drivers/mtd/multi_partition/用到了device/hisilicon下的驱动函数实
现，这样导致三方芯片适配时，会依赖hisilicon的驱动。
2. HDF的mtd驱动提供了这几个函数的实现，但是未暴露头文件出来。

【修改方案】
1. 修改BUILD.gn去除/device/hisilicon的依赖。
2. 修改mtd_partition.c，将hisilicon的头文件改为hdf的头文件依赖。

【遗留问题】
liteos-a内核与HDF mtd驱动的分界线还不明确，导致依赖关系不清楚

4. 对外公共头文件统一抽到对外include路径
5. 废弃宏，头文件清理

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
