[GitHub] [incubator-nuttx] Ouss4 opened a new pull request #4677: arch/*_cpupause:Allow a spin before taking the g_cpu_wait spinlock.

Ouss4 opened a new pull request #4677:
URL: https://github.com/apache/incubator-nuttx/pull/4677


   ## Summary
   If we repeatedly call up_cpu_pause and up_cpu_resume, there would be
   cases where the next call to up_cpu_pause happens while the other CPU is
   still responding to the previous resume request. In this case the
   DEBUGASSERT will trigger. We should allow the first CPU to wait until the
   other CPU has finished responding to the resume request.
   ## Impact
   Multi-core chips.
   ## Testing
   Tested with ESP32, see #4669
