For some reason they were missed previously. All those files seem to
have proper SDPX tags.
This patch improves the automatic console mode switching by avoiding
changing the mode if it can verify that the text is readable in the
default mode. The implementation avoids changing mode if we're using a
low resolution device (fixed to be smaller than 1920x1080) because we
assume the text is readable, so the initial mode should be a good one.
Also, the mode is not changed when in high resolution mode if the text
viewport area is larger than 10% of the screen. The conclusion is that
only if the text viewport is calculated to occupy less than 10% of the
screen area it is assumed to be hard to read and a new mode is selected.
With this patch the auto mode will typically avoid changing mode
hopefully in most of the cases, only changing it if completely
necessary.
The new boot option allows changing the display console mode to some new
display resolution.
Usage: in systemd-boot configuration file loader/loader.conf add one of:
console-mode <number>
console-mode auto
console-mode max
console-mode keep
Where number can be:
1) 0: UEFI standard 80x25 mode
2) 1: 80x50 mode, if supported by device
3) 2 or greater: some non-standard device mode, if supported
When using the auto mode, systemd-boot will try to find a reasonable
mode automatically using some heuristic. Current implementation tries to
switch console mode to mode 2 if it exists, mode 1 if it exists, else
mode 0. Mode 2 is the first non standard mode provided by the firmware
developer and it's assumed to be a reasonable mode.
The max mode adds support for switching to the highest numbered console
mode, whatever mode that would be in the system. The maximum mode being
the last one implemented by the firmware provider should be a reasonable
mode.
The keep mode is the default and is only included for completeness. With
this parameter, the user explicitly states and can be assured that
systemd-boot will not change console mode.
Note: patch includes a workaround for mode 1, that may not exist in
EDK2 OVFM and results in a buggy text mode when requested.
WaitForKeyEx may never return on some UEFI systems depending
on firmware, hardware configuration and the phase of the moon.
Use ConIn->WaitForKey unconditionally instead.
Fixes#3632
What used to be gummiboot, was renamed sd-boot when it was merged into
systemd. Let's try to be a bit more consistent with the rest of systemd
and rename it again as follows:
The EFI bootloader is now called 'systemd-bootx64.efi', and its sources are in
'src/boot/efi/'. The drop-in directory where bootctl will find EFI loaders
is now /usr/lib/systemd/boot/efi/.
