* [dpdk-dev] [PATCH v4] Move rte_mbuf macros to common header file
@ 2015-10-01 11:43 Ravi Kerur
0 siblings, 0 replies; 2+ messages in thread
From: Ravi Kerur @ 2015-10-01 11:43 UTC (permalink / raw)
To: dev
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
additionl header file inclusion is necessary.
v4:
> Remove un-necessary cast and braces in inline functions.
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

^ permalink raw reply [flat|nested] 2+ messages in thread* [dpdk-dev] [PATCH v4] Move rte_mbuf macros to common header file
@ 2015-10-01 11:58 Ravi Kerur
0 siblings, 0 replies; 2+ messages in thread
From: Ravi Kerur @ 2015-10-01 11:58 UTC (permalink / raw)
To: dev
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
additionl header file inclusion is necessary.
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
