[PATCH 0/2] x86/boot: provide better diagnostics in AP boot failure

Posted by Roger Pau Monne 8 months, 3 weeks ago

Hello,

Both patches attempt to improve AP boot failure diagnosis by improving
the printed failure messages (patch 1) and detecting AP getting stuck
during bringup (patch 2).  They should be non-functional changes for
systems working correctly.

Thanks, Roger.
