Subject: Re: [PATCH v10 09/12] cxl: Restore CXL HDM state after PCI reset
Date: Tue, 04 Aug 2026 19:44:40 +0000 [thread overview]
Message-ID: <20260804194441.96BCF1F000E9@smtp.kernel.org> (raw)
In-Reply-To: <20260804192958.1823952-10-smadhavan@nvidia.com>
> After CXL reset, restore PCI config state enough to reach HDM MMIO,
> restore cached global and per-decoder HDM state, and then run the normal
> PCI restore callbacks.
>
> Keep the target IOMMU reset block active until HDM restore completes so
> Bus Master Enable cannot reopen DMA before decoder state is valid.
