Does the current OpenWRT trunk support SMP (multi-processor/core)?

Looking over the current kernel configuration (https://dev.openwrt.org/browser/trunk/t … onfig-3.10) I dont see "CONFIG_SMP=y".  This would lead me to believe OpenWRT does not support SMP at this time (2/13/2014). :-(  If so, any reasons why?

Anyone?

Just checked on my new AMD T40E board from PCEngines: No, only one CPU supported. Also no HIMEM support, only 800MB RAM are supported. :-(

Strange kernel config for a x86 target. Most x86 processors today are multi-core. And more than 800MB is also pretty normal these days.

So, I guess I will need to look into kernel compilation myself...

Is there any known way to only make the kernel and all the modules as ipk packages?

That makes me sad.  I have the same issue(s).  I only see 1 CPU and 882MB ram.

root@OpenWrt:~# head -n1 /proc/meminfo

I have built many kernels, but I have no clue if you can make a new kernel with support for old modules. 

I would like to see a few things added to the kernel.  HighMEM, SMP and CPUFreq.  Now all that stated... This is a router/AP.  Not a DB.  Do you really need more than 128MB's ram?

Alternative concept that I have been pondering for some time.  Virtualize the hardware layer.  My person preference for this would be to use Xen, and use PCI pass through to attach the network cards directly into OpenWRT.  Just an idea.

Fixed. Apparently,

make kernel_menuconfig
allows setting SMP.

And looking at:
trunk/build_dir/target-x86_64_uClibc-0.9.33.2

[...]
CONFIG_X86_64_SMP=y

BUT the generic image should have it enabled:
https://downloads.openwrt.org/snapshots … _64/config

Where is this file stored, so I can propose a patch?
