[Qemu-devel] [PATCH] pc-bios: petalogix-s3adsp1800.dtb: Use 'xlnx, xps-ethernetlite-2.00.a' instead of 'xlnx, xps-ethernetlite-2.00.b'

[Qemu-devel] [PATCH] pc-bios: petalogix-s3adsp1800.dtb: Use 'xlnx, xps-ethernetlite-2.00.a' instead of 'xlnx, xps-ethernetlite-2.00.b'

For Linux upstream kernel (e.g. 3.17-rc7), the related compatible string
'xlnx,xps-ethernetlite-2.00.a' is supported, but 'b' is not supported,
so change qemu dtb file to match kernel driver.

The related operation for qemu (after this patch):

   yum install libvirt
   yum install tunctl
   tunctl -b
   ip link set tap0 up
   brctl addif virbr0 tap0

   ./configure
   make
   ./microblaze-softmmu/qemu-system-microblaze -M petalogix-s3adsp1800 \
     -kernel ../linux-stable.microblaze/arch/microblaze/boot/linux.bin \
     -no-reboot -append "console=ttyUL0,115200 doreboot" -nographic \
     -net nic,vlan=0,model=xlnx.xps-ethernetlite,macaddr=00:16:35:AF:94:00 \
     -net tap,vlan=0,ifname=tap0,script=no,downscript=no

   in microblaze qemu bash (guest machine):

     ifconfig eth0 add 192.168.122.2 netmask 255.255.255.0
     ifconfig eth0 up

   Then can telnet 192.168.122.2 directly without password from the host
   machine.

The related operation for generating new dtb:

   building Linux kernel firstly, then get dts tool "./scripts/dts/dts".
   "./scripts/dtc/dtc -I dtb -O dts  -o ../work.dts ../qemu/petalogix-s3adsp1800.dtb"
   edit work.dts (replace 'xlnx,xps-ethernetlite-2.00.b')
   "./scripts/dtc/dtc -I dts -O dtb  -o ..qemu/petalogix-s3adsp1800.dtb ../work.dts"

(Since I am not quite sure whether can read this patch or not, I put the
related dtb file in attachment, please check, thanks).

/me does not know anything about this stuff at all.  But anyway...

Is it a binary-only file without source?  Where it come from?

(it is not a simple question, eg, on Debian, binary files are
disallowed (at least in main section)).

Thanks,

As far as I know, It is a hardware description file. Can convert it to dts
format which is a text file, then can read and edit it, after finish, can
convert it to dtb format again.

dts and dtb can convert with each other without any information lost.
One tool for converting is "scripts/dts/dts" in upstream kernel (after
finish building kernel).

So for me, we can also treat dtb file as open source file. It is integrated
into qemu in 2009 (please "git log -p" to this file for more details).

Thanks.

Oh well.  I don't like this patch to be lost, but I must admit I don't
understand what's happening here.  Applied to -trivial.

Thanks,

OK, thank you for your work. And I shall try to make another patch for
qemu within this month.


Thanks.
