Subject: [Intel-wired-lan] [PATCH iwl-net v1 0/3] Rework ctrl_pf pointer usage in struct ice_adapter
Date: Mon, 4 May 2026 11:00:55 +0000 [thread overview]
Message-ID: <20260504110058.2373236-1-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.
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
