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.

Previous version:
https://lists.osuosl.org/pipermail/intel-wired-lan/Week-of-Mon-20260511/055077.html

v1->v2: Rebase onto the latest dev-queue branch
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
