V8: - simplify dmb definition to use io barriers (David Marchand) - define wfe() and sev() macros and use them inside normal C code (Ananyev Konstantin) - pass memorder as parameter, not to incorporate it into function name, less functions, similar to C11 atomic intrinsics (Ananyev Konstantin) - remove mandating RTE_FORCE_INTRINSICS in arm spinlock implementation(David Marchand) - undef __WAIT_UNTIL_EQUAL after use (David Marchand) - add experimental tag and warning (David Marchand) - add the limitation of using WFE instruction in the commit log (David Marchand) - tweak the use of RTE_FORCE_INSTRINSICS(still mandatory for aarch64) and RTE_ARM_USE_WFE for spinlock (David Marchand) - drop the rte_ring patch from this series, as the rte_ring.h calls this API and it is widely included by a lot of components each requires the ALLOW_EXPERIMENRAL_API for the Makefile and meson.build, leave it to future after the experimental is removed. V7: - fix the checkpatch LONG_LINE_COMMENT issue V6: - squash the RTE_ARM_USE_WFE configuration entry patch into the new API patch - move the new configuration to the end of EAL - add doxygen comments to reflect the relaxed and acquire semantics - correct the meson configuration V5: - add doxygen comments for the new APIs - spinlock early exit without wfe if the spinlock not taken by others. - add two patches on top for opdl and thunderx V4: - rename the config as CONFIG_RTE_ARM_USE_WFE to indicate it applys to arm only - introduce a macro for assembly Skelton to reduce the duplication of code - add one patch for nxp fslmc to address a compiling error V3: - Convert RFCs to patches V2: - Use inline functions instead of marcos - Add load and compare in the beginning of the APIs - Fix some style errors in asm inline V1: - Add the new APIs and use it for ring and locks Gavin Hu (5): bus/fslmc: fix the conflicting dmb function eal: add the APIs to wait until equal ticketlock: use new API to reduce contention on aarch64 net/thunderx: use new API to save cycles on aarch64 event/opdl: use new API to save cycles on aarch64 config/arm/meson.build | 1 + config/common_base | 5 + drivers/bus/fslmc/mc/fsl_mc_sys.h | 8 +- drivers/event/opdl/Makefile | 1 + drivers/event/opdl/meson.build | 1 + drivers/event/opdl/opdl_ring.c | 5 +- drivers/net/thunderx/Makefile | 1 + drivers/net/thunderx/meson.build | 1 + drivers/net/thunderx/nicvf_rxtx.c | 3 +- .../common/include/arch/arm/rte_pause_64.h | 70 +++++++ lib/librte_eal/common/include/generic/rte_pause.h | 217 +++++++++++++++++++++ .../common/include/generic/rte_ticketlock.h | 3 +- 12 files changed, 304 insertions(+), 12 deletions(-) -- 2.7.4
