V12: - remove the 'rte_' prefix from the arm specific functions (David Marchand) - use the __atomic_load_ex_xx functions in arm specific implementations of APIS (David Marchand) - remove the experimental warnings (David Marchand) - tweak the macros working scope (David Marchand) V11: -add rte_ prefix to the __atomic_load_ex_x funtions(Ananyev Konstantin) -define the above rte_atomic_load_ex_x funtions even if not RTE_WAIT_UNTIL_EQUAL_ARCH_DEFINED for future non-wfe usages(Ananyev Konstantin) -use the above functions for arm specific rte_wait_until_equal_x functions(Ananyev Konstantin) -simplify the generic implementation by immersing "if" into "while"(Ananyev Konstantin)
V10: - move arm specific stuff to arch/arm/rte_pause_64.h(Ananyev Konstantin) V9: - fix a weblink broken (David Marchand) - define rte_wfe and rte_sev() (Ananyev Konstantin) - explicitly define three function APIs instead of marcos (Ananyev Konstantin) - incorporate common rte_wfe and rte_sev into the generic rte_spinlock (David Marchand) - define arch neutral RTE_WAIT_UNTIL_EQUAL_ARCH_DEFINED (Ananyev Konstantin) - define rte_load_ex_16/32/64 functions to use load-exclusive instruction for aarch64, which is required for wake up of WFE - drop the rte_spinlock patch from this series, as the it calls this experimental 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. 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 | 165 +++++++++++++++++++++ lib/librte_eal/common/include/generic/rte_pause.h | 99 +++++++++++++ .../common/include/generic/rte_ticketlock.h | 3 +- 12 files changed, 281 insertions(+), 12 deletions(-) -- 2.7.4
