Subject: [PATCH iwl-net v3 0/3] Rework ctrl_pf pointer usage in struct ice_adapter
Date: Mon, 1 Jun 2026 09:19:48 +0000 [thread overview]
Message-ID: <20260601091951.3017848-1-sergey.temerkhanov@intel.com> (raw)
Rework usage of the control PF pointer in struct ice_adapter, so that
it is always has a consistent state, since it is global for an adapter.
Utilize RCU for reading the pointer value and atomic operations for
changing it. Zero out the ctrl_pf pointer when the control PF is removed.

v2->v3: Cosmetic fixes
Sergey Temerkhanov (3):
ice: Convert ctrl_pf pointer in struct ice_adapter to RCU
ice: Zero out the PTP control PF pointer at ice_adapter cleanup
ice: Cache struct ice_hw pointer for split register reads
