The resulting PMD supports both hardware versions. The main differences between the DLB v2.5 and v2.0 hardware are: - Number of queues/ports - DLB v2.5 uses a combined credit pool, whereas DLB v2.0 splits credits into 2 pools, a directed credit pool and a load balanced credit pool. - Different register maps, with different bit names and offsets In order to support both hardware versions with the same PMD, and avoid code duplication, the file dlb2_resource.c required a complete rewrite. This required some creative staging of the changes in order to keep the individual patches relatively small, while also meeting the requirement that all individual patches in the set compile cleanly. To accomplish this, a few temporary files are used: dlb2_hw_types_new.h dlb2_resources_new.h dlb2_resources_new.c As dlb2_resources_new.c is populated with the new combined v2.0/v2.5 low level logic, the corresponding old code is removed from dlb2_resource.c, thus allowing both the original and new code to continue to compile and link cleanly. Once all of the code has been migrated to the new model, the old versions of the files are removed, and the new versions are renamed, effectively replacing the old original files. As you review the code, you can ignore the code deletions from dlb2_resource.c, as that file continues to shrink as the new corresponding logic is added to dlb2_resource_new.c. Changes since V2: 1) fix commit headers 2) fix commit message repeated words 3) remove FPGA reference 4) split out new v2.5 register definitions into separate patch 5) fixed documentation to use DLB and dlb_event exclusively, instead of the old names such as dlb1_event, dlb2_event, DLB2, ... Final doc updates are done in patch that performs device rename from DLB2 tosimply DLB 6) use component event/dlb at commit which changes device name and all subsequent commits 7) Move all DLB constants out of config/rte_config.h except QUELL_STATS, which is used in the fastpath. Exposed these as devarg command line parameters 8) Removed "TEMPORARY" comment leftover in dlb2_osdep.h 9) squashed 20-21 and 22-23 since they were logically the same as 19-20, which was requested to be squashed 10) delete old dlb2.rst - dlb.rst has been updated for v2.0 and v2.1 Changes since V1: 1) Simplified subject text for all patches 2) correct typos/spelling 3) remove FPGA references 4) remove stale sysconf() references 5) fixed patches that had compilation issues 6) updated release notes 7) renamed dlb device from dlb2_event to dlb_event 8) moved dlb2 directory to dlb,to match name change 9) fixed other cases where "dlb2" was being used externally Timothy McDaniel (26): event/dlb2: add v2.5 probe event/dlb2: add v2.5 HW register definitions event/dlb2: add v2.5 HW init event/dlb2: add v2.5 get resources event/dlb2: add v2.5 create sched domain event/dlb2: add v2.5 domain reset event/dlb2: add V2.5 create ldb queue event/dlb2: add v2.5 create ldb port event/dlb2: add v2.5 create dir port event/dlb2: add v2.5 create dir queue event/dlb2: add v2.5 map qid event/dlb2: add v2.5 unmap queue event/dlb2: add v2.5 start domain event/dlb2: add v2.5 credit scheme event/dlb2: add v2.5 queue depth functions event/dlb2: add v2.5 finish map/unmap event/dlb2: add v2.5 sparse cq mode event/dlb2: add v2.5 sequence number management event/dlb2: use new implementation of resource header event/dlb2: use new implementation of resource file event/dlb2: use new implementation of HW types header event/dlb2: use new combined register map event/dlb2: update xstats for v2.5 doc/dlb2: update documentation for v2.5 event/dlb: remove version from device name event/dlb: move rte config defines to runtime devargs MAINTAINERS | 6 +- app/test/test_eventdev.c | 6 +- config/rte_config.h | 8 +- doc/api/doxy-api-index.md | 2 +- doc/api/doxy-api.conf.in | 2 +- doc/guides/eventdevs/{dlb2.rst => dlb.rst} | 155 +- doc/guides/eventdevs/index.rst | 2 +- doc/guides/rel_notes/release_21_05.rst | 5 + drivers/event/{dlb2 => dlb}/dlb2.c | 550 ++- drivers/event/{dlb2 => dlb}/dlb2_iface.c | 0 drivers/event/{dlb2 => dlb}/dlb2_iface.h | 0 drivers/event/{dlb2 => dlb}/dlb2_inline_fns.h | 0 drivers/event/{dlb2 => dlb}/dlb2_log.h | 0 drivers/event/{dlb2 => dlb}/dlb2_priv.h | 177 +- drivers/event/{dlb2 => dlb}/dlb2_selftest.c | 8 +- drivers/event/{dlb2 => dlb}/dlb2_user.h | 27 +- drivers/event/{dlb2 => dlb}/dlb2_xstats.c | 70 +- drivers/event/{dlb2 => dlb}/meson.build | 4 +- .../{dlb2 => dlb}/pf/base/dlb2_hw_types.h | 106 +- .../event/{dlb2 => dlb}/pf/base/dlb2_osdep.h | 2 + .../{dlb2 => dlb}/pf/base/dlb2_osdep_bitmap.h | 0 .../{dlb2 => dlb}/pf/base/dlb2_osdep_list.h | 0 .../{dlb2 => dlb}/pf/base/dlb2_osdep_types.h | 0 drivers/event/dlb/pf/base/dlb2_regs.h | 4304 +++++++++++++++++ .../{dlb2 => dlb}/pf/base/dlb2_resource.c | 3278 +++++++------ .../{dlb2 => dlb}/pf/base/dlb2_resource.h | 28 +- drivers/event/{dlb2 => dlb}/pf/dlb2_main.c | 37 +- drivers/event/{dlb2 => dlb}/pf/dlb2_main.h | 0 drivers/event/{dlb2 => dlb}/pf/dlb2_pf.c | 67 +- .../rte_pmd_dlb2.c => dlb/rte_pmd_dlb.c} | 6 +- .../rte_pmd_dlb2.h => dlb/rte_pmd_dlb.h} | 12 +- drivers/event/{dlb2 => dlb}/version.map | 2 +- drivers/event/dlb2/pf/base/dlb2_mbox.h | 596 --- drivers/event/dlb2/pf/base/dlb2_regs.h | 2527 ---------- drivers/event/meson.build | 2 +- 35 files changed, 6921 insertions(+), 5068 deletions(-) rename doc/guides/eventdevs/{dlb2.rst => dlb.rst} (72%) rename drivers/event/{dlb2 => dlb}/dlb2.c (89%) rename drivers/event/{dlb2 => dlb}/dlb2_iface.c (100%) rename drivers/event/{dlb2 => dlb}/dlb2_iface.h (100%) rename drivers/event/{dlb2 => dlb}/dlb2_inline_fns.h (100%) rename drivers/event/{dlb2 => dlb}/dlb2_log.h (100%) rename drivers/event/{dlb2 => dlb}/dlb2_priv.h (77%) rename drivers/event/{dlb2 => dlb}/dlb2_selftest.c (99%) rename drivers/event/{dlb2 => dlb}/dlb2_user.h (97%) rename drivers/event/{dlb2 => dlb}/dlb2_xstats.c (94%) rename drivers/event/{dlb2 => dlb}/meson.build (89%) rename drivers/event/{dlb2 => dlb}/pf/base/dlb2_hw_types.h (80%) rename drivers/event/{dlb2 => dlb}/pf/base/dlb2_osdep.h (99%) rename drivers/event/{dlb2 => dlb}/pf/base/dlb2_osdep_bitmap.h (100%) rename drivers/event/{dlb2 => dlb}/pf/base/dlb2_osdep_list.h (100%) rename drivers/event/{dlb2 => dlb}/pf/base/dlb2_osdep_types.h (100%) create mode 100644 drivers/event/dlb/pf/base/dlb2_regs.h rename drivers/event/{dlb2 => dlb}/pf/base/dlb2_resource.c (68%) rename drivers/event/{dlb2 => dlb}/pf/base/dlb2_resource.h (99%) rename drivers/event/{dlb2 => dlb}/pf/dlb2_main.c (95%) rename drivers/event/{dlb2 => dlb}/pf/dlb2_main.h (100%) rename drivers/event/{dlb2 => dlb}/pf/dlb2_pf.c (91%) rename drivers/event/{dlb2/rte_pmd_dlb2.c => dlb/rte_pmd_dlb.c} (88%) rename drivers/event/{dlb2/rte_pmd_dlb2.h => dlb/rte_pmd_dlb.h} (88%) rename drivers/event/{dlb2 => dlb}/version.map (60%) delete mode 100644 drivers/event/dlb2/pf/base/dlb2_mbox.h delete mode 100644 drivers/event/dlb2/pf/base/dlb2_regs.h -- 2.23.0
