Date: Thu, 10 Sep 2026 08:32:10 +0000 [thread overview]
Message-ID: <20260910083211.60E611F000FF@smtp.kernel.org> (raw)
In-Reply-To: <20260910082734.3771675-3-wanglin@open-hieco.net>
> On bare-metal Hygon systems, CPUID 0x8000001E ECX[7:0] encodes a
> CPU's socket and local CDD ordinal. The value is sparse across sockets
> and cannot be used as an index into the dense DF node cache.
>
> Translate the CPUID value through the CDDs sorted by socket and DFID.
> The NodeId reported by CPUID in a guest may not describe the physical
> DF topology. Return -ENODEV in guests or when the NodeId does not
> identify an enumerated CDD.
