[edk2-devel] [PATCH] Platform/Intel: Dynamic NUMBER_OF_PROCESSORS in build.
Posted by Chiu, Chasel 6 years, 8 months ago 
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1913

To improve build performance by default the maximum
processors should be used for building.
To support this, NUMBER_OF_PROCESSORS in build.cfg has
new definition:
  0 = AUTO. Maximum of processors will be used.
  non-zero = limit or force the number of processors.

Test: tried several NUMBER_OF_PROCESSORS settings and
      the build parameter can be updated accordingly
      also builds successfully.

Re: [edk2-devel] [PATCH] Platform/Intel: Dynamic NUMBER_OF_PROCESSORS in build.
Posted by Bob Feng 6 years, 8 months ago 
Hi Chasel,

Patch looks good.

For the process number, build.py does the same thing as this patch. If pass -n 0 to build.py, build.py will set the processor number to multiprocessing.cpu_count()

Thanks,
Bob

Thanks Bob! I was not aware that BaseTools already handled this.
I just verified and it works so I will update code review which will only touch build.cfg.

Thanks!
Chasel
