Hi，all，
I figured out why the igb_uio.ko file would not be generated, so I needed to 
modify the config file: CONFIG_RTE_EAL_IGB_UIO=y.
However, I encountered a new "error", but the compilation did not terminate. I 
looked at the compilation process and couldn't explain why the information was 
printed.

Re: [vpp-dev] dpdk-20.02 compile error for Intel atom

2020-04-28 Thread mythosmonkeyking 
Hi，all，
I ran into a new problem: when I cross compiled DPDK and don't found igb_uio.ko 
generated, what went wrong?
compile command as follows:

make config T=x86_64-silvermont-linux-gcc 
RTE_KERNELDIR=/home/mythos/kernel/linux-3.10 V=1
make V=1

make examples T=x86_64-silvermont-linux-gcc 
RTE_KERNELDIR=/home/mythos/kernel/linux-3.10 V=1
make install DESTDIR=$PWD/../tmp

I looked at the kernel version of the compiled server, as follows:

[root@localhost x86_64-silvermont-linux-gcc]# uname -a
Linux localhost 3.10.0-1062.12.1.el7.x86_64 #1 SMP Tue Feb 4 23:02:59 UTC 2020

Hi，Damjan Marion，
I figured out what the problem was. Atom had been replaced by silvermont, but 
in DPDK, instead of using code name, you should use abbreviations.

Re: [vpp-dev] dpdk-20.02 compile error for Intel atom

2020-04-25 Thread Damjan Marion via lists.fd.io 

looks like your compiler version is so old that it doesn’t know about 
silvermont. You need newer one suggest gcc-8 at least.

Also if i read it right, you use kernel 3.10, suggest using something newer. 
VPP uses syscalls which are not available in kernel 3.10

Re: [vpp-dev] dpdk-20.02 compile error for Intel atom

2020-04-15 Thread Benoit Ganne (bganne) via lists.fd.io 
As pointed to by Damjan, the issue is you are using the wrong arch parameter: 
you should be using 'silvermont' instead of 'atom' according to your cpu.

Re: [vpp-dev] dpdk-20.02 compile error for Intel atom

2020-04-15 Thread mythosmonkeyking 
hi, Damjan Marion, Benoit Ganne,
I want to cross compile DPDK on the build server.The CPU of the target host is 
Intel atom.Therefore, I added the atom platform under the mk/machine/ directory 
of DPDK, but an error occurred.
And when I looked at the CPU features, I found that my build server supported 
the sse4.1 feature.Why is this still the case?

Re: [vpp-dev] dpdk-20.02 compile error for Intel atom

2020-04-14 Thread Damjan Marion via lists.fd.io 

+1, -march=atom is bad, you likely have newer ATOM CPU, so consider using 
-march={silvermont,goldmont,goldmont-plus}.

What exact CPU are you targeting?

Hi,

This is a dpdk issue, not a VPP issue. However, it looks like your target does 
not support SSE4.1 which seems to be needed by librte_acl.
