Subject: [PATCH v5 2/2] config/arm: disable SVE ACLE for cn10k
Date: Thu, 19 May 2022 18:58:30 +0530	[thread overview]
Message-ID: <20220519132830.3677023-2-rbhansali@marvell.com> (raw)
In-Reply-To: <20220519132830.3677023-1-rbhansali@marvell.com>

This disable the sve_acle flag for cn10k.

For native build, -Dplatform=cn10k will require to
get sve_acle flag parameter in the build.

Performance impact:-
With l3fwd example, lpm lookup performance increased
by ~21% if Neon is used instead of SVE. Hence, disabled
sve_acle flag for cn10k.
