[edk2-devel] [Patch V3 1/2] MinPlatformPkg: console redirect after the shell is loaded

Heng Luo heng.luo at intel.com
Wed Nov 4 05:33:43 UTC 2020


REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3014

Use SerialPortTerminalLib to get console redirect after the shell is
loaded:
1. Add SerialPortTerminalLib to MinPlatformPkg/Library, add PCDs to
 configure serial port.
2. Add SerialPortTerminalLib to BdsDxe driver, to add the serial device to
 ConIn and ConOut variables
3. Include SerialDxe and TerminalDxe to CoreDxeInclude.dsc and
 CoreUefiBootInclude.fdf.
4. Use PcdSerialTerminalEnable to enable/disable this feature.
