Subject: [PATCH net v1 0/2] avoid compiler and IQ/OQ reordering
Date: Fri, 19 Dec 2025 07:29:51 +0000 [thread overview]
Message-ID: <20251219072955.3048238-1-vimleshk@marvell.com> (raw)
Utilize READ_ONCE and WRITE_ONCE APIs to prevent compiler
optimization and reordering. Ensure IO queue OUT/IN_CNT
registers are flushed. Relocate IQ/OQ IN/OUT_CNTS updates
to occur before NAPI completion, and replace napi_complete
with napi_complete_done.
