[GitHub] [incubator-nuttx] v01d opened a new issue #3344: ISSUES WITH ACCESSING CPU INDEX

[GitBox <gi...@apache.org>]

v01d opened a new issue #3344:
URL: https://github.com/apache/incubator-nuttx/issues/3344


   ```
     Description: The CPU number is accessed usually with the macro this_cpu().
                  The returned CPU number is then used for various things,
                  typically as an array index.  However, if pre-emption is
                  not disabled,then it is possible that a context switch
                  could occur and that logic could run on another CPU with
                  possible fatal consequences.
   
                  We need to evaluate all use of this_cpu() and assure that
                  it is used in a way that guarantees the the code continues
                  to execute on the same CPU.
   
     Status:      Open
     Prioity:     Medium.  This is a logical problem but I have never seen
                  an bugs caused by this.  But I believe that failures are
                  possible.
