Subject: [RFC v2 01/11] eal: use intrinsics for rte_atomic on all platforms
Date: Thu, 21 May 2026 11:04:13 -0700 [thread overview]
Message-ID: <20260521180706.678377-2-stephen@networkplumber.org> (raw)
In-Reply-To: <20260521180706.678377-1-stephen@networkplumber.org>
Next step is to deprecate the rte_atomicNN_*() family. Rather than
maintaining both the inline asm and intrinsic fallbacks, drop the
asm paths and use intrinsics everywhere.
