dpdk compress code

24 Nov 2022

dpdk compress code is almost ready.
https://github.com/Linaro/dpdk/tree/next-11.24-compress.

The dpdk only support deflate, 
We added some hack to use zlib, which will be removed when testing deflate
-                       setup.alg_type = WD_ZLIB;
+                       setup.alg_type = WD_DEFLATE;

-       udev = wd_get_accel_dev("zlib");
+       udev = wd_get_accel_dev("deflate");

Test:
https://github.com/Linaro/dpdk/blob/next-11.24-compress/doc/guides/compressdevs/uadk.rst

Prepare hugepage, only one time
echo 1024 > /sys/devices/system/node/node0/hugepages/hugepages-2048kB/nr_hugepages
echo 1024 > /sys/devices/system/node/node1/hugepages/hugepages-2048kB/nr_hugepages
echo 1024 > /sys/devices/system/node/node2/hugepages/hugepages-2048kB/nr_hugepages
echo 1024 > /sys/devices/system/node/node3/hugepages/hugepages-2048kB/nr_hugepages

mkdir -p /mnt/huge_2mb
mount -t hugetlbfs none /mnt/huge_2mb -o pagesize=2MB

Test app
    sudo dpdk-test --vdev=compress_uadk
