Dear Linux folks,
According to `systemd-analyze` the UEFI firmware on several systems, for
example the laptop Dell Latitude E7250 and the desktop board MSI B350M
MORTAR, take over ten seconds to initialize.
Startup finished in 11.193s (firmware) + 1.558s (loader) + 4.155s
(kernel) + 2.007s (userspace) = 18.914s
graphical.target reached after 1.983s in userspace
Talking to other people, I heard, Microsoft Windows since version 8 can
activate some fast/quick boot mode in the firmware.
I havenât even found the specification for that mode. It could be
something like , but I do not think it is:
Fast Boot is a feature in BIOS that reduces your computer boot time. If
Fast Boot is enabled:
â Boot from Network, Optical, and Removable Devices are disabled.
â Video and USB devices (keyboard, mouse, drives) won't be available
until the operating system loads.
Some other sources  say, that MS Windows just uses hibernation to
boot quicker, but I do not think this is it, because with hibernation
there should be also a ten seconds delay, right?
Do you know more about this mode, and how it works? Could it be
implemented for Linux?
