From c46fd358070f22ba68d6e74c22016a33b914c20a Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Tue, 28 Nov 2017 16:43:50 -0600 Subject: PCI/ASPM: Enable Latency Tolerance Reporting when supported Enable Latency Tolerance Reporting (LTR). Note that LTR must be enabled in the Root Port first, and must not be enabled in any downstream device unless the Root Port and all intermediate Switches also support LTR. See PCIe r3.1, sec 6.18.

Those drivers share a lot of code, so sometimes they live in the same source file. The host bridge driver requires CONFIG_PCI=y because it enumerates PCI devices below the bridge using the PCI core. The endpoint driver does not require CONFIG_PCI=y because it runs in an embedded kernel on the other side of the device, e.g., on an adapter card. pci-dra7xx.c contains both host and endpoint drivers. If we select only the endpoint driver (CONFIG_PCI=n and CONFIG_PCI_DRA7XX_EP=y), the unneeded host driver is still compiled. It references pci_irqd_intx_xlate(), which is not present when CONFIG_PCI=n, which causes this error: drivers/pci/dwc/pci-dra7xx.c:229:11: error: 'pci_irqd_intx_xlate' undeclared here (not in a function) Add a dummy pci_irqd_intx_xlate() for the CONFIG_PCI=n case.

Routing and completion do not require software support. Component support for each is detectable via the DEVCAP2 register. A Requester may use AtomicOps only if its PCI_EXP_DEVCTL2_ATOMIC_REQ is set. This should be set only if the Completer and all intermediate routing elements support AtomicOps. A concrete example is the AMD Fiji-class GPU (which is capable of making AtomicOp requests), below a PLX 8747 switch (advertising AtomicOp routing) with a Haswell host bridge (advertising AtomicOp completion support). Add pci_enable_atomic_ops_to_root() for per-device control over AtomicOp requests. This checks to be sure the Root Port supports completion of the desired AtomicOp sizes and the path to the Root Port supports routing the AtomicOps.

Remove the boilerplate GPL version 2 or later language, relying on the assertion in b24413180f56 ("License cleanup: add SPDX GPL-2.0 license identifier to files with no license") that the SPDX identifier may be used instead of the full boilerplate text.

Indeed the extracted lines of code were duplicated by many host controller drivers. Regrouping them into a generic function gives a change to properly share this code without introducing a useless dependency to PCI_HOST_COMMON, which selects PCI_ECAM when not needed by most host controller drivers.
