Dear team, The following patch set is intended to support DPDK running on LoongArch architecture.
LoongArch is the general processor architecture of Loongson Corporation and is a new RISC ISA, which is a bit like MIPS or RISC-V. The online documents of LoongArch architecture are here: https://loongson.github.io/LoongArch-Documentation/README-EN.html The latest build tools for LoongArch (binary) can be downloaded from: https://github.com/loongson/build-tools If you want to generate your own cross toolchain, you can refer to this thread: https://inbox.dpdk.org/dev/53b50799-cb29-7ee6-be89-4fe21566e...@loongson.cn/T/#m1da99578f85894a4ddcd8e39d8239869e6a501d1 >From the link above, you can find a script to do that. v8: - rebase the patchset on the main repository - add meson build test for LoongArch in devtools/test-meson-builds.sh - add ccache to build configuration file - change the cpp meson variable to a c++ compiler - complete the cross compilation documentation for LoongArch, adding reference to the build script and dependency list - put the feature description for LoongArch in the EAL features list in release_22_11.rst - simplify macro definition for new added headers - put the items about LoongArch in the right place in meson.build v7: - rebase the patchset on the main repository - add errno.h to rte_power_intrinsics.c according with commit 72b452c5f259 v6: - place some blocks for LoongArch in a pseudo alphabetical order - remove some macros not used - update release notes in the correct format - remove some headers for LoongArch, including msclock, pflock and ticketlock, which are now non-arch specific - rename some helpers to make them more readable - remove some copied comments - force-set RTE_FORCE_INTRINSICS in config and remove non-arch specific implementations - fix format errors in meson file reported by check-meson.py - rebase the patchset on the main repository v5: - merge all patches for supporting LoongArch EAL into one patch - add LoongArch cross compilation document and update some documents related to architecture - remove vector stubs added for LoongArch in net/i40e and net/ixgbe - add LOONGARCH64 cross compilation job in github ci v4: - rebase the patchset on the main repository of version 22.07.0 v3: - add URL for cross compile tool chain - remove rte_lpm_lsx.h which was a dummy vector implementation because there is already a scalar implementation, thanks to Michal Mazurek - modify the name of compiler for cross compiling - remove useless variable in meson.build v2: - use standard atomics of toolchain to implement atomic operations - implement spinlock based on standard atomics Min Zhou (6): eal/loongarch: support LoongArch architecture net/ixgbe: add vector stubs for LoongArch net/memif: set memfd syscall ID on LoongArch net/tap: set BPF syscall ID for LoongArch examples/l3fwd: enable LoongArch operation test/cpuflags: add test for LoongArch cpu flag MAINTAINERS | 6 ++ app/test/test_cpuflags.c | 41 ++++++++ app/test/test_xmmt_ops.h | 12 +++ .../loongarch/loongarch_loongarch64_linux_gcc | 16 +++ config/loongarch/meson.build | 43 ++++++++ devtools/test-meson-builds.sh | 4 + doc/guides/contributing/design.rst | 2 +- .../cross_build_dpdk_for_loongarch.rst | 97 +++++++++++++++++++ doc/guides/linux_gsg/index.rst | 1 + doc/guides/nics/features.rst | 8 ++ doc/guides/nics/features/default.ini | 1 + doc/guides/nics/features/ixgbe.ini | 1 + doc/guides/rel_notes/release_22_11.rst | 7 ++ drivers/net/i40e/meson.build | 6 ++ drivers/net/ixgbe/ixgbe_rxtx.c | 7 +- drivers/net/memif/rte_eth_memif.h | 2 + drivers/net/tap/tap_bpf.h | 2 + examples/l3fwd/l3fwd_em.c | 8 ++ lib/eal/linux/eal_memory.c | 4 + lib/eal/loongarch/include/meson.build | 18 ++++ lib/eal/loongarch/include/rte_atomic.h | 47 +++++++++ lib/eal/loongarch/include/rte_byteorder.h | 40 ++++++++ lib/eal/loongarch/include/rte_cpuflags.h | 39 ++++++++ lib/eal/loongarch/include/rte_cycles.h | 47 +++++++++ lib/eal/loongarch/include/rte_io.h | 18 ++++ lib/eal/loongarch/include/rte_memcpy.h | 61 ++++++++++++ lib/eal/loongarch/include/rte_pause.h | 24 +++++ .../loongarch/include/rte_power_intrinsics.h | 20 ++++ lib/eal/loongarch/include/rte_prefetch.h | 47 +++++++++ lib/eal/loongarch/include/rte_rwlock.h | 42 ++++++++ lib/eal/loongarch/include/rte_spinlock.h | 64 ++++++++++++ lib/eal/loongarch/include/rte_vect.h | 65 +++++++++++++ lib/eal/loongarch/meson.build | 11 +++ lib/eal/loongarch/rte_cpuflags.c | 93 ++++++++++++++++++ lib/eal/loongarch/rte_cycles.c | 45 +++++++++ lib/eal/loongarch/rte_hypervisor.c | 11 +++ lib/eal/loongarch/rte_power_intrinsics.c | 53 ++++++++++ meson.build | 2 + 38 files changed, 1012 insertions(+), 3 deletions(-) create mode 100644 config/loongarch/loongarch_loongarch64_linux_gcc create mode 100644 config/loongarch/meson.build create mode 100644 doc/guides/linux_gsg/cross_build_dpdk_for_loongarch.rst create mode 100644 lib/eal/loongarch/include/meson.build create mode 100644 lib/eal/loongarch/include/rte_atomic.h create mode 100644 lib/eal/loongarch/include/rte_byteorder.h create mode 100644 lib/eal/loongarch/include/rte_cpuflags.h create mode 100644 lib/eal/loongarch/include/rte_cycles.h create mode 100644 lib/eal/loongarch/include/rte_io.h create mode 100644 lib/eal/loongarch/include/rte_memcpy.h create mode 100644 lib/eal/loongarch/include/rte_pause.h create mode 100644 lib/eal/loongarch/include/rte_power_intrinsics.h create mode 100644 lib/eal/loongarch/include/rte_prefetch.h create mode 100644 lib/eal/loongarch/include/rte_rwlock.h create mode 100644 lib/eal/loongarch/include/rte_spinlock.h create mode 100644 lib/eal/loongarch/include/rte_vect.h create mode 100644 lib/eal/loongarch/meson.build create mode 100644 lib/eal/loongarch/rte_cpuflags.c create mode 100644 lib/eal/loongarch/rte_cycles.c create mode 100644 lib/eal/loongarch/rte_hypervisor.c create mode 100644 lib/eal/loongarch/rte_power_intrinsics.c -- 2.32.1 (Apple Git-133)
