Subject: Re: [PATCH v2 3/6] PCI/EDR: Remove CONFIG_PCIE_EDR
Date: Tue, 20 Oct 2026 18:30:06 +0000 [thread overview]
Message-ID: <sashiko-outbox-179475@kernel.org> (raw)
In-Reply-To: <20261020181924.3003553-4-sathyanarayanan.kuppuswamy@linux.intel.com>
> Error Disconnect Recover (EDR) is the ACPI half of the hybrid DPC model,
> where firmware owns DPC and notifies the OS of containment events.
>
> CONFIG_PCIE_EDR made EDR optional on top of CONFIG_PCIE_DPC. This adds
> another knob to the decision to request DPC control in _OSC. The OS
> requests DPC control only if it also supports EDR, so with
> CONFIG_PCIE_EDR=n it never requests DPC control. There is little reason
> to build DPC without EDR on ACPI systems.
>
> Remove the option and build edr.c whenever CONFIG_PCIE_DPC and
> CONFIG_ACPI are both enabled.
