Subject: [PATCH RESEND net v1 0/2] avoid compiler and IQ/OQ reordering
Date: Thu, 12 Feb 2026 12:16:30 +0000 [thread overview]
Message-ID: <20260212121634.360252-1-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.
Resending based on discussion with reviewer.
