CNXK product families can have a use case to allow PF and VF applications to communicate using mailboxes and also get notified of any interrupt that may occur on the device. Hence, a new raw device driver is added for such RVU LF devices. These devices can map to a PF or a VF which can send mailboxes to each other. The RVU LF device implements following features in the rawdev API:
- Register mailbox callbacks for the other side to process mailboxes. - Register interrupt handler callbacks. - Process mailbox. - Set range of message IDs allowed for communication. Changes in v6: - Addressed comments from Jerin on documentation Changes in v5: - fixed checkpatch Changes in v4: - moved all PMD APIs to internal APIs to be exposed via enable_driver_sdk meson option. - added missing version.map entries as internal APIs. - separate out selftest in a separate file - fixed logs Changes in v3: - fix internal/external header files. Changes in v2: - removed library patch from series - removed PMD logs from external PMD header. - updated doc/api/doxy-api-index.md - Added release notes Akhil Goyal (9): drivers/raw: introduce cnxk rvu lf device driver raw/cnxk_rvu_lf: support NPA/SSO pffunc get raw/cnxk_rvu_lf: support interrupt callback registration raw/cnxk_rvu_lf: support msg handler registration raw/cnxk_rvu_lf: support to set message ID range raw/cnxk_rvu_lf: support mailbox processing raw/cnxk_rvu_lf: support device pffunc get raw/cnxk_rvu_lf: support getting BAR addresses raw/cnxk_rvu_lf: add selftest MAINTAINERS | 6 + doc/guides/platform/cnxk.rst | 5 + doc/guides/rawdevs/cnxk_rvu_lf.rst | 109 ++++++++ doc/guides/rawdevs/index.rst | 1 + doc/guides/rel_notes/release_24_11.rst | 5 + drivers/common/cnxk/meson.build | 1 + drivers/common/cnxk/roc_api.h | 3 + drivers/common/cnxk/roc_constants.h | 3 + drivers/common/cnxk/roc_dev.c | 118 +++++++- drivers/common/cnxk/roc_dev_priv.h | 7 + drivers/common/cnxk/roc_idev.c | 46 +++ drivers/common/cnxk/roc_idev.h | 4 + drivers/common/cnxk/roc_idev_priv.h | 1 + drivers/common/cnxk/roc_mbox.h | 2 + drivers/common/cnxk/roc_npa.c | 6 + drivers/common/cnxk/roc_npa.h | 3 + drivers/common/cnxk/roc_priv.h | 2 + drivers/common/cnxk/roc_rvu_lf.c | 202 ++++++++++++++ drivers/common/cnxk/roc_rvu_lf.h | 46 +++ drivers/common/cnxk/roc_rvu_lf_priv.h | 37 +++ drivers/common/cnxk/roc_sso.c | 6 + drivers/common/cnxk/roc_sso.h | 3 + drivers/common/cnxk/roc_utils.c | 2 + drivers/common/cnxk/version.map | 16 ++ drivers/raw/cnxk_rvu_lf/cnxk_rvu_lf.c | 262 ++++++++++++++++++ drivers/raw/cnxk_rvu_lf/cnxk_rvu_lf.h | 26 ++ drivers/raw/cnxk_rvu_lf/cnxk_rvu_lf_driver.h | 218 +++++++++++++++ .../raw/cnxk_rvu_lf/cnxk_rvu_lf_selftest.c | 166 +++++++++++ drivers/raw/cnxk_rvu_lf/meson.build | 11 + drivers/raw/cnxk_rvu_lf/version.map | 16 ++ drivers/raw/meson.build | 1 + 31 files changed, 1328 insertions(+), 6 deletions(-) create mode 100644 doc/guides/rawdevs/cnxk_rvu_lf.rst create mode 100644 drivers/common/cnxk/roc_rvu_lf.c create mode 100644 drivers/common/cnxk/roc_rvu_lf.h create mode 100644 drivers/common/cnxk/roc_rvu_lf_priv.h create mode 100644 drivers/raw/cnxk_rvu_lf/cnxk_rvu_lf.c create mode 100644 drivers/raw/cnxk_rvu_lf/cnxk_rvu_lf.h create mode 100644 drivers/raw/cnxk_rvu_lf/cnxk_rvu_lf_driver.h create mode 100644 drivers/raw/cnxk_rvu_lf/cnxk_rvu_lf_selftest.c create mode 100644 drivers/raw/cnxk_rvu_lf/meson.build create mode 100644 drivers/raw/cnxk_rvu_lf/version.map -- 2.25.1
