This series covers minimal changes for item #2 in draft plan for EAL dependencies kvargs, telemetry and consumed EAL public headers. Note if any patch in the series requires in-depth discussion I'll detach it from this series for separate submission & more focused discussion so it doesn't block the entire series. Note other "common" intrinsics were investigated for viability but were not adopted either because they were not available on older versions of gcc or because they generate different code for msvc vs gcc. v6: * convert / expand likely/unlikely macros to _Bool type * expand __extension__ empty it's cleaner to do this for now instead of modifying the whole tree * provide msvc container_of not based on gcc expression statement extension * add patch that stops defining typeof (C23 keyword) when building with msvc v5: * remove accidental line removal in barrier patch * update prefetch patch to use intrinsics for all toolchains * remove x86 specific changes for byte swap patch since msvc intrinsics are processor agnostic always use intrinsics from generic include * expand __rte_packed empty for msvc packing will be addressed in a separate series v4: * update rdtsc patch to use gcc intrinsics * update rtm patch to use gcc intrinsics * drop patch disable json print formatting, we will utilize series removing VLAs from Bruce * added patch using prefetch intrinsics for msvc * added patch using byte swap intrinsics for msvc * added patch hiding typdefs for msvc using gcc vector extension * added patch defining MSVC as little endian always v3: * v3 does not group together conditional blocks when experimented with it didn't reduce conditionals enough to make it worth while. once msvc tests are at a running point i suggest a narrow targeted discussion about code organization without blocking this series * v3 does not attempt to refactor to use intrinsics for non-msvc compilers. again this should be done as a separate follow-up series later if desired * fix expansion of likely and unlikely macros * remove unnecessary define for rte_smp_{r,w}mb it is sufficient for these to be compiler barriers on x86 * add a new patch to use __cpuid and __cpuidex intrinsics when building with msvc * add a new patch to use _umonitor, _umwait and _tpause intrinsics when building with msvc v2: * use _mm_{l,s,m}fence intrinsics for rte_smp_{r,w,}mb macros are intended to be memory barriers not compiler barriers on x86_64 Tyler Retzlaff (15): eal: use rdtsc intrinsic eal: use rtm and xtest intrinsics eal: use barrier intrinsics eal: use cpuid and cpuidex intrinsics eal: use umonitor umwait and tpause intrinsics eal: use prefetch intrinsics eal: use byte swap intrinsics eal: typedef cpu flag enum as int eal: hide GCC extension based alignment markers eal: hide typedefs based on GCC vector extensions eal: expand most macros to empty when using MSVC eal: exclude exposure of rte atomic APIs for MSVC builds telemetry: avoid expanding versioned symbol macros on MSVC eal: always define MSVC as little endian eal: do not define typeof macro when building with MSVC config/x86/meson.build | 6 ++++ lib/eal/include/generic/rte_atomic.h | 11 ++++++ lib/eal/include/generic/rte_byteorder.h | 13 +++++++ lib/eal/include/generic/rte_cpuflags.h | 12 ++++--- lib/eal/include/generic/rte_vect.h | 4 +++ lib/eal/include/rte_branch_prediction.h | 8 +++++ lib/eal/include/rte_common.h | 60 +++++++++++++++++++++++++++++++++ lib/eal/include/rte_compat.h | 20 +++++++++++ lib/eal/x86/include/rte_atomic.h | 8 +++++ lib/eal/x86/include/rte_byteorder.h | 4 +++ lib/eal/x86/include/rte_cycles.h | 14 ++++---- lib/eal/x86/include/rte_prefetch.h | 25 +++++++++++--- lib/eal/x86/include/rte_rtm.h | 18 +++------- lib/eal/x86/rte_cpuflags.c | 4 +++ lib/eal/x86/rte_cpuid.h | 7 ++++ lib/eal/x86/rte_cycles.c | 36 ++++++++++++++++++++ lib/eal/x86/rte_hypervisor.c | 4 +++ lib/eal/x86/rte_power_intrinsics.c | 12 +++++++ lib/telemetry/telemetry_data.c | 16 +++++++++ 19 files changed, 254 insertions(+), 28 deletions(-) -- 1.8.3.1
