Hi Florin,
Thank you for the reply.
I am trying to develop similar kind of envoy app using VCL. So, I need both
socket option for binary API and shared client for rx/tx for TCP data.
So, I need use-mq-eventfd at vcl.conf right?. ANyway I tried removing it
but still same issue.
my VCL:
======
vcl {
rx-fifo-size 400000
tx-fifo-size 400000
app-scope-global
api-socket-name /run/vpp/api.sock
}
=========
My VPP startup.conf:
==================
unix {
nodaemon
log /var/log/vpp/vpp.log
full-coredump
cli-listen /run/vpp/cli.sock
}
api-trace {
on
}
socksvr {
default
}
cpu {
main-core 1
corelist-workers 2,3,4,5,6,7
}
buffers {
buffers-per-numa 128000
}
dpdk {
dev default {
num-rx-queues 1
num-tx-queues 1
num-rx-desc 4096
num-tx-desc 4096
}
dev 0000:00:06.0
dev 0000:00:09.0
no-multi-seg
socket-mem 2048,0
}
plugins
{
path
/usr/cna/bld-dataplane_base/base//cni-infra-dataplane/fdio/src/fdio/build-root/build-vpp_debug-native/vpp/lib/vpp_plugins/
}
====================
At VPP code:
===========
in function:
482 static int
483 application_alloc_and_init (app_init_args_t * a)
484 {
485 ssvm_segment_type_t seg_type = SSVM_SEGMENT_MEMFD;
486 segment_manager_props_t *props;
487 vl_api_registration_t *reg;
488 application_t *app;
489 u64 *options;
490
...............
496 if (!(options[APP_OPTIONS_FLAGS] & APP_OPTIONS_FLAGS_IS_BUILTIN))
497 {
498 reg = vl_api_client_index_to_registration
(a->api_client_index);
499 if (!reg)
500 return VNET_API_ERROR_APP_UNSUPPORTED_CFG;
501 if (vl_api_registration_file_index (reg) == VL_API_INVALID_FI)
502 seg_type = SSVM_SEGMENT_SHM;
503 }
504 else
505 {
506 seg_type = SSVM_SEGMENT_PRIVATE;
507 }
508
509 if ((options[APP_OPTIONS_FLAGS] &
APP_OPTIONS_FLAGS_EVT_MQ_USE_EVENTFD)
510 && seg_type != SSVM_SEGMENT_MEMFD)
511 {
512 clib_warning ("mq eventfds can only be used if socket
transport is "
513 "used for binary api");
514 return VNET_API_ERROR_APP_UNSUPPORTED_CFG;
515 }
516
517 if (!application_verify_cfg (seg_type))
518 return VNET_API_ERROR_APP_UNSUPPORTED_CFG;
...........
}
Its hitting at 518 return error i.e application_verify_cfg (seg_type)
....seg_type = SSVM_SEGMENT_MEMFD;
gdb:
====
(gdb) p seg_type
$22 = SSVM_SEGMENT_MEMFD
(gdb) n
492 options = a->options;
(gdb) p *a
$23 = {api_client_index = 0, name = 0x7fffce651780 "vcl_test_client[shm]",
options = 0x7ffad802af02, namespace_id = 0x7fffce651750 "",
session_cb_vft = 0x7ffff7f3f4e8 <session_mq_cb_vft>, app_index = 0}
(gdb) p *a->options
$24 = 163
With Regards
