Re: [vpp-dev] Unable to create sub-interface with 'untagged' option

[Gudimetla, Leela Sankar]

I also see the same error while creating a sub interface with untagged option. 
The parent physical interface is UP when creating the sub-interface.
Curious to know.

Thanks,

Re: [vpp-dev] VPP's C-type-api example

hi all,
Thanks at first.
But I got some error when using vapi - vapi_connect as " vl_map_shmem:639: 
region init fail ".
And my mem : MemFree:  220036 kB  |   HugePages_Total:

Help please!

My code:
int main()
{
  vapi_ctx_t ctx;
  vapi_error_e rv = vapi_ctx_alloc ();
  vapi_msg_show_version *sv = vapi_alloc_show_version (ctx);
  rv = vapi_connect (ctx, app_name, api_prefix, max_outstanding_requests,
 response_queue_size, VAPI_MODE_BLOCKING);
  rv = vapi_send (ctx, sv);
  vapi_msg_show_version_reply *reply;
  rv = vapi_recv (ctx, (void **) , NULL, 0, 0);
  if(reply != NULL)
  printf("ret[%d] program[%s] version[%s] \n build_date[%s]

  rv = vapi_disconnect (ctx);
  vapi_ctx_free (ctx);

You can also check out the test/ext directory for vapi_c_test.c and
vapi_cpp_test.cpp, which are unittests for these bindings and there is
also an example of _dump API call.

Permission error?
Run client as root, or configure VPP to set permissions on API shared memory.
 
In VPP startup:
api-segment { uid  gid  }

You can also check out the test/ext directory for vapi_c_test.c and
vapi_cpp_test.cpp, which are unittests for these bindings and there is
also an example of _dump API call.

Re: [vpp-dev] hqos configuration in vpp (Connection refused)

[Jasvinder Singh]

Hi Reza,

I tested HQoS on my fedora system as below and found it working, didn’t see any 
issue;


1.   Make build

2.   Make run STARTUP_CONF=startup.conf

3.   DGBvpp#

startup.conf

unix {
interactive
log /tmp/vpp.log
cli-listen /run/vpp/cli.sock
full-coredump
}

dpdk {
socket-mem 8192,8192

dev :02:00.0 {num-rx-queues 2 hqos}
dev :02:00.1 {num-rx-queues 2 hqos}

num-mbufs 100

}

cpu {
main-core 0
corelist-workers 1,2,3,4
corelist-hqos-threads  5,6
}

Thanks,
Jasvinder

Subject: [vpp-dev] hqos configuration in vpp (Connection refused)


Hi

I want to config vpp in a way that it can use hqos according to this 
tutorial, but when i set hqos 
feature for an interface in /etc/vpp/starttup.conf and then restart vpp 
service, it's not clear for me that why vpp service can not be started. can 
anyone help me to solve this problem?

My modifications on /etc/vpp/startup.conf are as follows:



 ...

 cpu {

 main-core 0
 corelist-workers 1, 2
 corelist-hqos-threads 3
 }

 dpdk {

 socket-mem 2048,2048

 dev :0b:00.0 {
 num-rx-queues 2 hqos
 }

 num-mbufs 100

 }

...



Output of vppctl command after service vpp restart:

   clib_socket_init: connect (fd 3, '/run/vpp/cli.sock'): Connection 
refused



Best regards

Reza

Re: [vpp-dev] VPP's C-type-api example

[Ole Troan]

Hi again,

That’s right, I wouldn’t recommend using the src/vpp-aoi/client API unless you 
are building a new language binding.

If you need a C interface you should use VAPI.

See interface.api.vapi.h (auto-generated) for sw_interface_dump()

static inline vapi_error_e vapi_sw_interface_dump(struct vapi_ctx_s *ctx,
  vapi_msg_sw_interface_dump *msg,
  vapi_error_e (*callback)(struct vapi_ctx_s *ctx,
   void *callback_ctx,
   vapi_error_e rv,
   bool is_last,
   vapi_payload_sw_interface_details *reply),
  void *callback_ctx)


src/vpp-api/vapi/vapi_doc.md for documentation.

To get a feel of how the API works, at even higher level you can play with the 
Python language binding.

Best regards,
Ole

Is the main cause those python segfaults?
Figuring out what triggers that python bug might be a start.
