Subject: Re: [PATCH v6 1/8] x86/hygon: Add Family 0x18 DF node enumeration
Date: Mon, 21 Sep 2026 06:02:36 +0000 [thread overview]
Message-ID: <20260921060238.E346B1F000FF@smtp.kernel.org> (raw)
In-Reply-To: <20260921055603.25112-2-wanglin@open-hieco.net>
> The AMD node code locates function 3 for node N at PCI slot 0x18 + N.
> Hygon has no equivalent node-index-to-slot mapping: DF F3 devices are
> discovered by PCI ID and the PCI BDF is only an access point.
>
> Add a Hygon node cache that enumerates DF devices by PCI ID and obtains
> the socket ID and DFID for each node from DF configuration registers.
> Validate the enumerated socket set against the hardware-reported socket
> mask before making the cache available.
>
> Place Core and DDR Dies (CDDs) before I/O Dies (IODs) and order each
> group by socket and DFID to provide dense node indices. Export
> interfaces for node counts and identity, F3/F4 lookup, and PCI
> device-to-node lookup.
