efi_loader: Fix warning in raw/cols query

2018-06-03T13:51:19+00:00

The code to determine rows / cols on the screen could potentially run
into a case where it doesn't know how big the screen is. In that case,
assume 80x25.

efi_loader: avoid using unitialized values as console size

2018-06-03T13:27:20+00:00

If a request for the console size would be answered with a response
with less then three values, uninitialized stack memory would be
copied to the number of rows and columns of the terminal.

efi_loader: always check parameters in efi_cout_query_mode()

2018-06-03T13:27:20+00:00

If we cannot determine the size of the serial terminal we still have
to check the parameters of efi_cout_query_mode().

Querying the size of the serial terminal drains the keyboard buffer.
So make sure we do this during the initialization and not in the midst
of an EFI application.

efi_loader: updating the cursor position

2018-06-03T13:27:20+00:00

The current coding advances the column by the number of UTF-8 bytes.
The column should be increased by one per unicode character.

The UEFI spec provides advance rules for U+0000, U+0008, U+000A,
and U000D. All other characters, including control characters
U+0007 (bel) and U+0009 (tab), have to increase the column by one.

SPDX: Convert a few files that were missed before

2018-05-11T00:38:35+00:00

As part of the main conversion a few files were missed.  These files had
additional whitespace after the '*' and before the SPDX tag and my
previous regex was too strict.  This time I did a grep for all SPDX tags
and then filtered out anything that matched the correct styles.

efi_loader: implement event groups

2018-04-04T09:00:07+00:00

If an event of a group event is signaled all other events of the same
group are signaled too.

Function efi_signal_event is renamed to efi_queue_event.
A new function efi_signal_event is introduced that checks if an event
belongs to a group and than signals all events of the group.
Event group notifciation is implemented for ExitBootServices,
InstallConfigurationTable, and ResetSystem.

efi_loader: remove deprecated ConsoleControlProtocol

2018-04-04T09:00:06+00:00

The console control protocol is not defined in the UEFI standard.

It exists in EDK2's EdkCompatiblityPkg package. But this package
is deprecated according to

efi_loader: add check_tpl parameter to efi_signal_event

2018-01-22T22:09:14+00:00

In ExitBootServices we need to signal events irrespective of the current
TPL level. A new parameter check_tpl is added to efi_signal_event().

Function efi_console_timer_notify() gets some comments.

We should consistently use the efi_handle_t typedef when
referring to handles.
