Subject: Re: [PATCH v10 04/12] cxl: Cache decoder settings on PCI devices
Date: Tue, 04 Aug 2026 19:40:42 +0000 [thread overview]

In-Reply-To: <20260804192958.1823952-5-smadhavan@nvidia.com>
> Add CXL core plumbing to refresh a PCI device HDM decoder cache when
> decoders are enumerated, committed, or reset. PCI reset paths can use
> this snapshot to restore HDM programming without walking CXL topology
> during reset recovery.
>
> The cache is populated by PCI-side discovery in a follow-on patch. Until
> then, the CXL core update path is a no-op when no PCI HDM cache is
> present.
