From: Wei Hu <[email protected]> Add support for handling hardware service reset events in the MANA driver. When the MANA kernel driver receives a hardware service event, it initiates a device reset and notifies userspace via IBV_EVENT_DEVICE_FATAL. The MANA PMD handles this by performing an automatic teardown and recovery sequence.
The driver uses ethdev recovery events (ERR_RECOVERING, RECOVERY_SUCCESS, RECOVERY_FAILED) to notify upper layers of the reset lifecycle, and a PCI device removal event callback to distinguish hot-remove from service reset. Changes since v1: - Removed net/netvsc patch from this series (will be submitted separately) - Simplified reset exit: mana_reset_exit now calls mana_reset_exit_delay directly instead of spawning a separate thread, since it already runs on mana_reset_thread - Added __rte_no_thread_safety_analysis annotations to fix clang -Wthread-safety build errors - Switched from rte_thread_create_control to rte_thread_create_internal_control per DPDK preference - Fixed declaration-after-statement style issues - Fixed stale comments and removed unnecessary blank lines - Added comments explaining intentionally ignored return values Wei Hu (1): net/mana: add device reset support drivers/net/mana/mana.c | 928 +++++++++++++++++++++++++++++++---- drivers/net/mana/mana.h | 33 +- drivers/net/mana/meson.build | 2 +- drivers/net/mana/mp.c | 89 +++- drivers/net/mana/mr.c | 6 +- drivers/net/mana/rx.c | 24 +- drivers/net/mana/tx.c | 40 +- 7 files changed, 1016 insertions(+), 106 deletions(-) -- 2.34.1
