[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] Re: [Xen-devel] XEN[ARM] Master not working on Allwinner A20
Thank you for your fast reaction Ian.
I have tested d9639236 with the smaller dom0 allocation.
256M is still giving me the same problem.
But 128M is working and booting the dom0 kernel.
Bootlog:

Reverting 6c21cb36 didn't help for me.
But I have also found another bug between 720f45ad..d9639236 in the DT
bootargs parsing.
When my DTS is:
xen,dom0-bootargs = "console=hvc0,115200n8 debug ignore_loglevel rw
rootwait earlyprintk=xen clk_ignore_unused ";
It successfully boots (but I can't mount my rootfs :( ), but when
dom0-bootargs is:
xen,dom0-bootargs = "console=hvc0,115200n8 debug ignore_loglevel rw
rootwait earlyprintk=xen clk_ignore_unused root=/dev/nfs
nfsroot=10.31.5.161:/export/cubie/rootfs,v3,tcp
ip=10.31.5.165:10.31.5.161:10.31.4.1:255.255.252.0:cubie:eth0:off";
It stays stuck on:

Because of this I can't test my system on master because I can't mount my
rootfs.
720f45ad Is working for me I can create multiple vm's but I get some
kernel messages when creating them:

And when I destroy a VM I get this:

The rootfs of dom0 is Ubuntu 13.04 and is mounted using NFS.
