[dpdk-dev] [PATCH v2 0/6] enable lpm, acl and other missing libraries in ppc64le

[Chao Zhu]

Gowrishankar,

When I tried the patches, I got some compilation error:

In file included from
/root/test/sub/dpdk/lib/librte_acl/acl_run_altivec.c:34:0:

  *indices1 = (xmm_t){((uint32_t *)&v)[0], ((uint32_t *)&v)[1],
  ^

  *indices2 = (xmm_t){((uint32_t *)&v)[0], ((uint32_t *)&v)[1],

Can you help to take a look?

Subject: [PATCH v2 0/6] enable lpm, acl and other missing libraries in
ppc64le

From: gowrishankar <gowrishankar.m at linux.vnet.ibm.com>

This patchset enables LPM, ACL and other few missing libs in ppc64le and
also address few patches in related examples (ip_pipeline and l3fwd).

Test report:
LPM and ACL unit tests verified as in patch set v1.
Same results as before observed.

v2 changes:
- enabling libs in config included as part of lib changes itself.

gowrishankar (6):
  lpm: add altivec intrinsics for dpdk lpm on ppc_64
  acl: add altivec intrinsics for dpdk acl on ppc_64
  ip_pipeline: fix lcore mapping for varying SMT threads as in ppc64
  table: cache align rte_bucket_4_8
  sched: enable sched library for ppc64le
  l3fwd: add altivec support for em_hash_key
