Subject: [PATCH 4/4] alpha: default NR_CPUS to 32 for Wildfire
Date: Thu, 1 Oct 2026 12:50:18 -0400 [thread overview]
Message-ID: <20261001165018.415526-4-mattst88@gmail.com> (raw)
In-Reply-To: <20261001165018.415526-1-mattst88@gmail.com>
The AlphaServer GS320 has up to 32 CPUs and the Wildfire code handles
all eight QBBs, but a Wildfire-only kernel defaults to NR_CPUS=4 and
ignores the rest unless the user raises it by hand.

The kernel supports at most 32 CPUs. Only Marvel and Wildfire
systems have more than 4.
