If the "-kernel" QEMU option is not used, then QemuKernelLoaderFsDxe
1d2c45
should return EFI_NOT_FOUND, so that the DXE Core can unload it. However,
1d2c45
the associated error message, logged by the DXE Core to the serial
1d2c45
console, is not desired in the silent edk2-aarch64 build, given that the
1d2c45
absence of "-kernel" is nothing out of the ordinary. Therefore, return
1d2c45
success and stay resident. The wasted guest RAM still gets freed after
1d2c45
ExitBootServices().
