如何在vxworks中检查正在运行的任务的占用空间？

Question

我想知道在vxworks(目标板)中检查应用程序的运行时占用空间的任何命令或实用程序.

我还想知道如何找到目标板的CPU使用率.

Answer 1

不太清楚"运行时占用"是什么意思,但ti命令会显示特定任务的堆栈使用情况:

-> ti tNet0

  NAME         ENTRY       TID    PRI   STATUS      PC       SP     ERRNO  DELAY
----------  ------------ -------- --- ---------- -------- -------- ------- -----
tNet0       ipcomNetTask 1040fad0  50 PEND       1014c42b 1078ff10       0     0

full task name : tNet0
task entry     : ipcomNetTask
process        : kernel
options        : 0x9007
VX_SUPERVISOR_MODE  VX_UNBREAKABLE      VX_DEALLOC_STACK    VX_DEALLOC_TCB     
VX_DEALLOC_EXC_STACK

STACK      BASE     END       SP      SIZE    HIGH   MARGIN
--------- -------- -------- -------- ------- ------- -------
execution 10790000 10780000 1078ff10   65536    2404   63132
exception 10428fb8 10426030            12168     360   11808

对于cpu使用,在BSP中启用INCLUDE_SPY并执行spy以开始显示cpu使用情况:
