Since this structure defines\nsome static arrays and changing respective macros breaks the ABI.\nEg:\nCurrently RTE_MAX_RXTX_INTR_VEC_ID imposes a limit of maximum 512\nMSI-X interrupts that can be defined for a PCI device, while PCI\nspecification allows maximum 2048 MSI-X interrupts that can be used.\nIf some PCI device requires more than 512 vectors, either change the\nRTE_MAX_RXTX_INTR_VEC_ID limit or dynamically allocate based on\nPCI device MSI-X size on probe time. Either way its an ABI breakage.\n\nChange already included in 21.11 ABI improvement spreadsheet (item 42):\nhttps://urldefense.proofpoint.com/v2/url?u=https-3A__docs.google.com_s\npreadsheets_d_1betlC000ua5SsSiJIcC54mCCCJnW6voH5Dqv9UxeyfE_edit-23gid-\n3D0&d=DwICaQ&c=nKjWec2b6R0mOyPaz7xtfQ&r=5ESHPj7V-7JdkxT_Z_SU6RrS37ys4U\nXudBQ_rrS5LRo&m=7dl3OmXU7QHMmWYB6V1hYJtq1cUkjfhXUwze2Si_48c&s=lh6DEGhR\nBg1shODpAy3RQk-H-0uQx5icRfUBf9dtCp4&e=\n\nThis series makes struct rte_intr_handle totally opaque to the outside\nworld by wrapping it inside a .c file and providing get set wrapper APIs\nto read or manipulate its fields.. Any changes to be made to any of the\nfields should be done via these get set APIs.\nIntroduced a new eal_common_interrupts.c where all these APIs are defined\nand also hides struct rte_intr_handle definition.\n\nv1:\n* Fixed freebsd compilation failure\n* Fixed seg fault in case of memif\n\nv2:\n* Merged the prototype and implementation patch to 1.\n* Restricting allocation of single interrupt instance.\n* Removed base APIs, as they were exposing internally\nallocated memory information.\n* Fixed some memory leak issues.\n* Marked some library specific APIs as internal.\n\nv3:\n* Removed flag from instance alloc API, rather auto detect\nif memory should be allocated using glibc malloc APIs or\nrte_malloc*\n* Added APIs for get/set windows handle.\n* Defined macros for repeated checks.\n\nv4:\n* Rectified some typo in the APIs documentation.\n* Better names for some internal variables.\n\nv5:\n* Reverted back to passing flag to instance alloc API, as\nwith auto detect some multiprocess issues existing in the\nlibrary were causing tests failure.\n* Rebased to top of tree.\n\nv6:\n* renamed RTE_INTR_INSTANCE_F_UNSHARED as RTE_INTR_INSTANCE_F_PRIVATE,\n* changed API and removed need for alloc_flag content exposure\n (see rte_intr_instance_dup() in patch 1 and 2),\n* exported all symbols for Windows,\n* fixed leak in unit tests in case of alloc failure,\n* split (previously) patch 4 into three patches\n * (now) patch 4 only concerns alarm and (previously) patch 6 cleanup bits\n are squashed in it,\n * (now) patch 5 concerns other libraries updates,\n * (now) patch 6 concerns drivers updates:\n * instance allocation is moved to probing for auxiliary,\n * there might be a bug for PCI drivers non requesting\n RTE_PCI_DRV_NEED_MAPPING, but code is left as v5,\n* split (previously) patch 5 into three patches\n * (now) patch 7 only hides structure, but keep it in a EAL private\n header, this makes it possible to keep info in tracepoints,\n * (now) patch 8 deals with VFIO/UIO internal fds merge,\n * (now) patch 9 extends event list,\n\nv7:\n* fixed compilation on FreeBSD,\n* removed unused interrupt handle in FreeBSD alarm code,\n* fixed interrupt handle allocation for PCI drivers without\n RTE_PCI_DRV_NEED_MAPPING,\n\nv8:\n* lowered logs level to DEBUG in sanity checks,\n* fixed corner case with vector list access,", "diff": null, "prefixes": [ "v8", "0/9" ] }
