lnlan 40338918d9 fix: 修复PR520缺陷
【背景】
https://gitee.com/openharmony/kernel_liteos_a/pulls/520
上面修改,信号处理时才会释放申请的内存,当信号被屏蔽,且一直发送该信号时,
内存占用会不断变大
【修改方案】
1.
信号发送时已经有该信号的siginfo在链表中时,不再重新申请,重复使用之前的siginfo.

【影响】
对现有的产品编译不会有影响。

zhushengle 298ccea3fe fix: 进程退出前自己回收vmspace中的所有region
背景:
父进程fork一个子进程,调用waitpid等待子进程结束。
子进程dlopen一个文件a.so,并退出。当守护进程正在
1核回收子进程资源时,父进程在0核运行从waitpid返
回后,同时remove a.so概率失败。

2021-09-29 02:48:49 +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

lnlan c3facd1b95 fix: 修复sigwait等待到的信号值与获取的siginfo中的值不一致
【背景】
集成测试发送两个不同的信号,sigwait第二次等到的仍是第一个信号
经定位,信号在kill时会将相关的siginfo信息拷贝到taskcb的unbinfo中,sigwait
处理时从unbinfo拷贝给用户。若此信号发送时处于屏蔽状态,再有其他信号发送会覆盖
掉unbinfo,此时sigwait等待这个信号获取到的info已经被覆盖
【修改方案】
1. 每个任务添加一个siginfo缓存链表,在处理信号前夕从缓存链表取出info到unbinfo中

【影响】
对现有的产品编译不会有影响。
