Status of autogen skipping


Daniel Schaefer
 

Hi,

we, as probably most users of EDK2, have a huge codebase with lots of modules.

Autogen takes multiple minutes, which is unnecessary when doing a rebuild. Luckily there is `--skip-autogen` but it only works if no INF, DSC, ... file has been changed. The developer needs to know when they can call that.

There seems to be a mechanism to automatically skip autogen for individual modules if they haven't been updated. However this doesn't seem to work anymore. I think the change that reverted this was the fix for:

by Bob in 3a7a6761143a4840faea0bd84daada3ac0f1bd22

Is there any plan to properly fix this? Because it would be a huge timesaver to have automatic autogen skipping.

Thanks,
Daniel
