Subject: [PATCH 0/4] implement runtime debug output protocl
Date: Thu, 1 Mar 2018 18:11:38 +0000 [thread overview]
Message-ID: <20180301181142.16817-1-ard.biesheuvel@linaro.org> (raw)
As discussed on list, MMIO based UARTs cannot be used at runtime without
taking special precautions to register the MMIO region and switch to the
virtual address when accessing it at runtime.
So extend the recently introduced DxeRuntimeDebugLibSerialPort library by
invoking the proposed RuntimeDebugOutput protocol at runtime if one is
available, and providing an implementation of this protocol for PL011.
Ard Biesheuvel (4):
MdePkg: move DxeRuntimeDebugLibSerialPort to MdeModulePkg
MdeModulePkg: introduce runtime debug output protocol
MdeModulePkg/DxeRuntimeDebugLibSerialPort: invoke
RuntimeDebugOutputProtocol
ArmPlatformPkg: add PL011 UART runtime debug driver
