Subject: [PATCH v7 4/4] x86: Tune 'Saltwell' microarch the same was a 'Bonnell'
Date: Wed, 10 May 2023 17:12:13 -0500	[thread overview]
Message-ID: <20230510221213.765754-3-goldstein.w.n@gmail.com> (raw)
In-Reply-To: <20230510221213.765754-1-goldstein.w.n@gmail.com>

Saltwell is just a die shrink of Bonnell, so the same
micro-architectural optimization preferences apply.
