The set of patches add IBM Power architecture to the DPDK. It adds the required support to the EAL library. This set of patches doesn't support full DPDK function on Power processors. So a separate common configuration file is used for Power to turn off some un-migrated functions. To compile on PPC64 architecture, GCC version >= 4.8 must be used. This v3 patch updates eal_memory.c to fix the memory zone allocation and also solves the compiling problems of test-pmd.
Chao Zhu (14): Add compiling definations for IBM Power architecture Add atomic operations for IBM Power architecture Add byte order operations for IBM Power architecture Add CPU cycle operations for IBM Power architecture Add prefetch operation for IBM Power architecture Add spinlock operation for IBM Power architecture Add vector memcpy for IBM Power architecture Add CPU flag checking for IBM Power architecture Remove iopl operation for IBM Power architecture Add cache size define for IBM Power Architecture Add huge page size define for IBM Power architecture Add eal memory support for IBM Power Architecture test_memzone:fix finding the second smallest segment Fix the compiling of test-pmd on IBM Power Architecture app/test-pmd/config.c | 33 +- app/test/test_cpuflags.c | 35 ++ app/test/test_malloc.c | 8 +- app/test/test_memzone.c | 123 ++++++- config/common_linuxapp_powerpc | 394 +++++++++++++++++++ config/defconfig_ppc_64-power8-linuxapp-gcc | 42 ++ config/defconfig_x86_64-native-linuxapp-clang | 1 + config/defconfig_x86_64-native-linuxapp-gcc | 1 + config/defconfig_x86_64-native-linuxapp-icc | 1 + lib/librte_eal/common/eal_common_memzone.c | 15 +- .../common/include/arch/ppc_64/rte_atomic.h | 415 ++++++++++++++++++++ .../common/include/arch/ppc_64/rte_byteorder.h | 150 +++++++ .../common/include/arch/ppc_64/rte_cpuflags.h | 184 +++++++++ .../common/include/arch/ppc_64/rte_cycles.h | 86 ++++ .../common/include/arch/ppc_64/rte_memcpy.h | 224 +++++++++++ .../common/include/arch/ppc_64/rte_prefetch.h | 61 +++ .../common/include/arch/ppc_64/rte_spinlock.h | 73 ++++ lib/librte_eal/common/include/rte_memory.h | 9 +- lib/librte_eal/common/include/rte_memzone.h | 8 + lib/librte_eal/linuxapp/eal/eal.c | 13 +- lib/librte_eal/linuxapp/eal/eal_memory.c | 75 +++- mk/arch/ppc_64/rte.vars.mk | 39 ++ mk/machine/power8/rte.vars.mk | 57 +++ mk/rte.cpuflags.mk | 17 + 24 files changed, 2015 insertions(+), 49 deletions(-) create mode 100644 config/common_linuxapp_powerpc create mode 100644 config/defconfig_ppc_64-power8-linuxapp-gcc create mode 100644 lib/librte_eal/common/include/arch/ppc_64/rte_atomic.h create mode 100644 lib/librte_eal/common/include/arch/ppc_64/rte_byteorder.h create mode 100644 lib/librte_eal/common/include/arch/ppc_64/rte_cpuflags.h create mode 100644 lib/librte_eal/common/include/arch/ppc_64/rte_cycles.h create mode 100644 lib/librte_eal/common/include/arch/ppc_64/rte_memcpy.h create mode 100644 lib/librte_eal/common/include/arch/ppc_64/rte_prefetch.h create mode 100644 lib/librte_eal/common/include/arch/ppc_64/rte_spinlock.h create mode 100644 mk/arch/ppc_64/rte.vars.mk create mode 100644 mk/machine/power8/rte.vars.mk
