[GitHub] [incubator-nuttx] masayuki2009 opened a new pull request #4209: Fix sim smp

masayuki2009 opened a new pull request #4209:
URL: https://github.com/apache/incubator-nuttx/pull/4209


   ## Summary
   
   - This commits consists of the following 2 commits
   - commit 1: Revert "arch: sim: Workaround to make the IPI work on macOS"
   - commit 2: arch: sim: Add NuttX symbols to make SMP work correctly
      - I noticed that sim:smp does not work correctly on macOS
         due to the recent changes
       - Actually, it can not receive the IPI host signal, so if
         a new task is scheduled on CPU1/2/3, it hangs.
       - Finally, I found that sim_cpu_start() calls pthread_attr_init()
         which locates not on the host OS but on the NuttX
       - This commit fixes this issue by adding the symbol names
         to nuttx-names.in
   
   ## Impact
   
     - sim in SMP mode
      - NOTE: stack usage for CPU1/2/3 IDLE is still incorrect on macOS
   
   ## Testing
   
    - Tested with ostest on Ubuntu 18.04 (x86_64) and macOS 11.4 (x86_64)
