Subject: [PATCH v2 0/1] net/mana: add device reset support
Date: Fri, 8 May 2026 23:01:12 -0700 [thread overview]
Message-ID: <20260509060113.61686-1-weh@linux.microsoft.com> (raw)
From: Wei Hu <weh@microsoft.com>
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
