I successfully built server and client. When I run server with posix satck, it running successful:
# ./server --port=13001 --smp=1 --cpuset=5 WARN 2019-07-01 20:48:02,704 [shard 0] seastar - Unable to set SCHED_FIFO scheduling policy for timer thread; latency impact possible.

When I run server with dpdk, it show me the error :
# ./server --port=13001 --smp=1 --cpuset=5 --dpdk-pmd --network-stack=native EAL: Detected 56 lcore(s) EAL: Detected 2 NUMA nodes EAL: Multi-process socket /var/run/dpdk/rte/mp_socket EAL: No available hugepages reported in hugepages-2048kB EAL: FATAL: Cannot get hugepage information. EAL: Cannot get hugepage information. EAL: Error - exiting with code: 1 Cause: Cannot init EAL
Could you give us any help?
You should configure the hugepage firstly. The steps like, as follows
sudo sh ./dpdk-setup.sh
Find "Setup hugepage mappings for NUMA systems"
sudo mkdir /mnt/huge
mount -t hugetlbfs nodev /mnt/huge
...
Thank you for your reply. When I choose "Setup hugepage mappings for NUMA systems", it always tells me permission denied. The output as follows:
# sudo bash ./dpdk/usertools/dpdk-setup.sh
...
[45] Setup hugepage mappings for NUMA systems
...
Option: 45
Removing currently reserved hugepages
.echo_tmp: 2: .echo_tmp: cannot create /sys/devices/system/node/node0/hugepages/hugepages-2048kB/nr_hugepages: Read-only file system
.echo_tmp: 3: .echo_tmp: cannot create /sys/devices/system/node/node1/hugepages/hugepages-2048kB/nr_hugepages: Read-only file system
Unmounting /mnt/huge and removing directory
Input the number of 2048kB hugepages for each node
Example: to have 128MB of hugepages available per node in a 2MB huge page system,
enter '64' to reserve 64 * 2MB pages on each node
Number of pages for node0: 64
Number of pages for node1: 64
Reserving hugepages
.echo_tmp: 2: .echo_tmp: cannot create /sys/devices/system/node/node0/hugepages/hugepages-2048kB/nr_hugepages: Read-only file system
.echo_tmp: 3: .echo_tmp: cannot create /sys/devices/system/node/node1/hugepages/hugepages-2048kB/nr_hugepages: Read-only file system
Creating /mnt/huge and mounting as hugetlbfs

emmm... If you are in docker environment, use --privileged
. In host environment, use sudo
?
