i've got two cleanly build mips64-64 initrds (based on cross linux
from scratch, gcc 6.1 and linux kernel 4.7) that i want to boot with qemu
initrd.cpio ~14.5 MB
big_initrd.cpio ~323.4 MB
(attached is the kernel output for both)
mips64-softmmu/qemu-system-mips64 -M malta -m 1GB -nographic -monitor
telnet::4440,server,nowait -serial telnet::3000,server -kernel
clfskernel-4.7.0 -initrd initrd.cpio
the smaller initrd.cpio (~14.5 MB) boots without any problem and shows
the output of an test-program at end of the booting
the big one with ~323.4 MB seems to hang right before the ramdisk/initrd
extraction
using the big_initrd the kernel comes to
Determined physical RAM map:
memory: 0000000010000000 @ 0000000000000000 (usable)
and stops then
some guys from the qemu mailing list pointed me to the lower 256MiB RAM
and HighMem (2GB) RAM Feature of the malta
is it possible to configure linux (configs or kernel-parameter?) to boot
my big_initrd from the highmem area?
