According to the UEFI spec, EFI_EVENT_GROUP_READY_TO_BOOT "is notified by
the system when the Boot Manager is about to load and execute a boot
option". ArmVirtPkg doesn't do this currently when launching a kernel from
the QEMU command line. OvmfPkg does (see git commit 28a34033ee).
At least two edk2-wide callbacks are worth mentioning:
- OnReadyToBoot() in
"MdeModulePkg/Universal/Variable/RuntimeDxe/VariableDxe.c" performs
variable reclaim and (optionally) installs variable usage statistics as
a vendor config table;
- OnReadyToBoot() in
"SecurityPkg/Library/DxeImageVerificationLib/DxeImageVerificationLib.c"
installs the image execution info table if it doesn't exist yet, in
SecureBoot-enabled builds.
