efi_loader: query serial console size reliably

2018-09-23T19:55:30+00:00

Not all terminals understand CSI [18t for querying the console size.
We should adhere to escape sequences documented in the console_codes
manpage and the ECMA-48 standard.

So here we follow a different approach. We position the cursor to the
bottom right and query its position. Before leaving the function we
restore the original cursor position.

efi_loader: terminal left upper corner is [1, 1]

2018-09-23T19:55:30+00:00

For the VT102 and the Linux console the left upper corner is [1, 1].
EFI uses [0, 0] as left upper corner.

Check parameters of the SetCursorPosition() service.

Use CSI H like EDK2 for positioning.

efi_loader: support Unicode text input

2018-09-23T19:55:30+00:00

Up to now the EFI_TEXT_INPUT_PROTOCOL only supported ASCII characters.
With the patch it can consume UTF-8 from the console.

Currently only the serial console and the console can deliver UTF-8.
Local consoles are restricted to ASCII.

efi_loader: struct efi_simple_text_input_protocol

2018-09-23T19:55:29+00:00

%s/efi_simple_input_interface/efi_simple_text_input_protocol/

We should be consistent in the naming of the EFI protocol interface
structures. The protocol is called EFI_SIMPLE_TEXT_INPUT_PROTOCOL.

%s/ExtendedVerification/extended_verification/

Use consistent naming of function parameters. Do not use CamelCase.
