[OpenWrt-Devel] OpenWRT 64bits kernel

[Jean Baptiste Favre (OpenWRT-devel)]

Hello,
I need to compile OpenWRT kernel as 2.6.37 64bits kernel in order to
track a bug in Xen PCI passthrough with Xen developpers. This bug seems
to occur only with 32bits kernels.

I compiled a working OpenWRT image  2.6.37 kernel (32bits).
Right after, I executed make clean and make from my 64bits env in
build_dir/linux-x86_xen_domu/linux-2.6.37.
Compilation goes well, but Xen domU crashed.

I succeed in running 32bits Debian domU with 64bits kernel, so I think I
could do the same with openWRT.

Is there anything else to do, like reverting some 32bits specific
pacthes ? If yes, which one ?

Regards,
JB

Hello everybody,

Just a quick mail to inform you that I succeed to make PCI passthrough
run with OpenWRT trunk and newly released Linux kernel 2.6.37 :)

I'll now write an howto

 Hello,
 I'm trying to make openwrt running under Xen with PCI passthrough.
 The idea is to give network cards control to openwrt domU and isolate
 dom0 and other domUs behind.
 
 Making openwrt domU running works well, but not PCI passthrough.
 I need Xen PCI frontend driver which does not seems to be packaged or
 activated, even in trunck branch with Linux 2.6.35.
 
 How can I add this driver to OpenWRT ?
