[dpdk-dev] [PATCH v5] mbuf: introduce common functions to get dma address
Olivier Matz
olivier.matz at 6wind.com
Fri Mar 4 10:09:40 CET 2016
From: Ravi Kerur <rkerur at gmail.com>
Macros RTE_MBUF_DATA_DMA_ADDR and RTE_MBUF_DATA_DMA_ADDR_DEFAULT
are defined in each PMD driver file. Convert macros to inline
functions and move them to common lib/librte_mbuf/rte_mbuf.h file.
PMD drivers include rte_mbuf.h file directly/indirectly hence no
additioanl header file inclusion is necessary.

Sorry, I missed this patch since a long time. So, instead of doing
very late comments on the v4, I prefered to submit an updated v5 with
some minor fixes.
v5:
> Rebase on master branch (new occurences to replace in nfp
driver and in virtio)
> add API comments above the new functions
> use phys_addr_t instead of uint64_t
v4:
> Remove un-necessary cast and braces in inline functions.
> Add 'const' for function parameters
v3:
> Changed converted macro->inline names to lower-case
> Fix checkpatch.pl errors and warnings
(camelcase warning is not fixed)
> Compiled following targets
> x86_64-native-linuxapp-clang
> x86_64-native-linuxapp-gcc
> i686-native-linuxapp-gcc
> x86_64-native-bsdapp-gcc
> x86_64-native-bsdapp-clang
> Tested on:
> x86_64 ubuntu 14.04, make test
v2:
> Changed both macros to inline functions in all PMD
> Changed macro to rte_pktmbuf_mtod in xenvirt module
> Compiled following targets:
> x86_64-native-linuxapp-clang
> x86_64-native-linuxapp-gcc
> i686-native-linuxapp-gcc
> Tested on:
> x86_64 ubuntu 14.04, testpmd and make test
v1:
> Move macros into common rte_mbuf header file.
> Compiled following targets:
> x86_64-native-linuxapp-clang
> x86_64-native-linuxapp-gcc
> i686-native-linuxapp-gcc
> x86_64-native-bsdapp-gcc
> x86_64-native-bsdapp-clang
Tested on:
> x86_64 Ubuntu 14.04, testpmd and make test
> FreeBSD 10.1, testpmd
