This patchset introduces several changes related to PMD power management: - Changed monitoring intrinsics to use callbacks as a comparison function, based on previous patchset [1] but incorporating feedback [2] - this hopefully will make it possible to add support for .get_monitor_addr in virtio - Add a new intrinsic to monitor multiple addresses, based on RTM instruction set and the TPAUSE instruction - Add support for PMD power management on multiple queues, as well as all accompanying infrastructure and example apps changes
v7: - Fixed various bugs v6: - Improved the algorithm for multi-queue sleep - Fixed segfault and addressed other feedback v5: - Removed "power save queue" API and replaced with mechanism suggested by Konstantin - Addressed other feedback v4: - Replaced raw number with a macro - Fixed all the bugs found by Konstantin - Some other minor corrections v3: - Moved some doc updates to NIC features list v2: - Changed check inversion to callbacks - Addressed feedback from Konstantin - Added doc updates where necessary [1] http://patches.dpdk.org/project/dpdk/list/?series=16930&state=* [2] http://patches.dpdk.org/project/dpdk/patch/819ef1ace187365a615d3383e54579e3d9fb216e.1620747068.git.anatoly.bura...@intel.com/#133274 Anatoly Burakov (7): power_intrinsics: use callbacks for comparison net/af_xdp: add power monitor support eal: add power monitor for multiple events power: remove thread safety from PMD power API's power: support callbacks for multiple Rx queues power: support monitoring multiple Rx queues l3fwd-power: support multiqueue in PMD pmgmt modes doc/guides/nics/features.rst | 10 + doc/guides/prog_guide/power_man.rst | 74 +- doc/guides/rel_notes/release_21_08.rst | 9 + drivers/event/dlb2/dlb2.c | 17 +- drivers/net/af_xdp/rte_eth_af_xdp.c | 34 + drivers/net/i40e/i40e_rxtx.c | 20 +- drivers/net/iavf/iavf_rxtx.c | 20 +- drivers/net/ice/ice_rxtx.c | 20 +- drivers/net/ixgbe/ixgbe_rxtx.c | 20 +- drivers/net/mlx5/mlx5_rx.c | 17 +- examples/l3fwd-power/main.c | 6 - lib/eal/arm/rte_power_intrinsics.c | 11 + lib/eal/include/generic/rte_cpuflags.h | 2 + .../include/generic/rte_power_intrinsics.h | 68 +- lib/eal/ppc/rte_power_intrinsics.c | 11 + lib/eal/version.map | 3 + lib/eal/x86/rte_cpuflags.c | 2 + lib/eal/x86/rte_power_intrinsics.c | 90 ++- lib/power/meson.build | 3 + lib/power/rte_power_pmd_mgmt.c | 659 +++++++++++++----- lib/power/rte_power_pmd_mgmt.h | 6 + 21 files changed, 840 insertions(+), 262 deletions(-) -- 2.25.1
