[edk2] [PATCH 0/3] Create UART DebugLib implementation for runtime drivers

Posted by Ard Biesheuvel 6 years, 10 months ago

Commit 4bf95a9f361e ("MdeModulePkg/ResetSystemRuntimeDxe: Add more debug
message") broke the DEBUG build for systems using a MMIO mapped UART for
DEBUG output.

Instead of patching it up locally, let's fix this issue once and for all,
by creating a UART DebugLib implementation that does the right thing by
default, and blacklisting the BASE version for use by DXE_RUNTIME_DRIVER
modules.

Ard Biesheuvel (3):
  MdePkg: introduce DxeRuntimeDebugLibSerialPort
  ArmVirtPkg: switch to DXE runtime version of DebugLib where
    appropriate
  MdePkg/BaseDebugLibSerialPort: blacklist for use by DXE runtime
    drivers
