Hi all,
I was doing more testing of UEFI in Xen guests and noticed some slow
down when using the shell. The characters are only echoed after a second
or two that is a bit annoying.
The change that introduced this issue is 4cf3f37c87 "MdeModulePkg
SerialDxe: Process timeout consistently in SerialRead".
The Serial Driver for Xen PV console is very simple (see
OvmfPkg/Library/XenConsoleSerialPortLib). So I am not sure where the
root cause is.
Would anyone have any tips on it?
Cheers,
