Subject: [PATCH 0/4] ArmPkg: use console for minimal 'exception occurred' message
Date: Thu, 20 Dec 2018 18:31:00 +0100 [thread overview]
Message-ID: <20181220173104.11481-1-ard.biesheuvel@linaro.org> (raw)
When running with a graphical console, no message whatsoever is printed
when the systems hits an unexpected exception and hangs, because even
the minimal 'exception occurred' message is only sent to the serial port.
So let's fix that, by updating DefaultExceptionHandlerLib to take the
availability of a console into account. (#4)
This requires some preparatory decruftication so that we can safely refer
to the system table and console (#1 .. #3).
Ard Biesheuvel (4):
ArmPkg/DebugAgentSymbolsBaseLib: remove exception handling
ArmPkg/DefaultExceptionHandlerLib: declare the permitted usage context
ArmPkg/DefaultExceptionHandlerLib: drop BASE variant
ArmPkg/DefaultExceptionHandlerLib: use console if available
