[edk2-devel] [PATCH v2 1/1] Platform/RaspberryPi: Setup option for disabling Fast Boot

Tue Apr 13 07:14:49 UTC 2021
This is a fix for https://github.com/pftf/RPi4/issues/114.
Changes:
1. Add a setup option called Boot Policy and consume the setting
during boot to whether perform or skip ConnectAll.
2. The Default setting is set to Full discovery because it is not
worth enabling Fast boot by default on RaspberryPi systems.
Enabling it just saves boot time about 1 second, but caused a
lot of issues.
Testing Done:
- Booted to Standalone UEFI shell on SD card and use drivers
command to check the result with Fast Boot and Full discovery
settings. Then, child/device handles are created as expected.
Note and to-do items:
- The root cause looks like that boot loaders and some tools like
grub and iPXE haven't supported selective connect/Fast boot.
However, system firmware should still provide a setup option for
user to enable Fast boot with old version boot loaders and tools
, which is why we proposed this change. We will also report this
issue to boot loader and tool vendors/open source GitHubs.
- We Will add more options for connecting specific type devices so
that we can still have the shortest boot time for all use cases.
