Subject: [Bug 63] AWS ENA driver does not work with zero rx queues.
Date: Thu, 21 Jun 2018 11:06:17 +0000 [thread overview]
Message-ID: <bug-63-3@http.bugs.dpdk.org/> (raw)
https://bugs.dpdk.org/show_bug.cgi?id=63
Bug ID: 63
Summary: AWS ENA driver does not work with zero rx queues.
Product: DPDK
Version: 18.02
Hardware: All
OS: Other
Status: CONFIRMED
Severity: major
Priority: Normal
Component: other
Assignee: dev@dpdk.org
Reporter: daria.kolistratova@intel.com
Target Milestone: ---
(Program received signal SIGFPE, Arithmetic exception.) which was caused by:
0x00000000006f703c in ena_rss_init_default (adapter=0x7fffef399200)
at
/home/ec2-user/projects/src/github.com/intel-go/nff-go/dpdk/dpdk-18.02/drivers/net/ena/ena_ethdev.c:571
571 val = i % nb_rx_queues;
nb_rx_queues is 0, cause our application does not receive and we do not use rx
queues.
After fix of SIGFPE, we cant init port cause ena_com_ind_tbl_convert_to_device
function returns error at line:
(if (io_sq->direction != ENA_COM_IO_QUEUE_DIRECTION_RX)
return ENA_COM_INVAL;)
cause place for rx queue is not initialized and 0 means tx queue.
Application may have no rx queues, please look at this case.
