PCI: cadence: Add EndPoint Controller driver for Cadence PCIe controller

2018-01-31T11:13:27+00:00

This patch adds support to the Cadence PCIe controller in endpoint mode. Since pieces of source code are shared with the host driver (Root Complex mode), we create a new directory under drivers/pci dedicated to the Cadence PCIe controller. The common code is placed into drivers/pci/cadence/pcie-cadence.c and used by both the host and endpoint controller drivers. Signed-off-by: Cyrille Pitchen Signed-off-by: Lorenzo Pieralisi

PCI: Regroup all PCI related entries into drivers/pci/Makefile

2018-01-31T11:09:20+00:00

Clean up drivers/Makefile by moving the pci/endpoint and pci/dwc entries from drivers/Makefile into drivers/pci/Makefile. Since we don't want to introduce any dependency between CONFIG_PCI and CONFIG_PCI_ENDPOINT, we now always execute drivers/pci/Makefile. Hence all Makefiles in drivers/pci/ were updated accordingly so no file is compiled when CONFIG_PCI is not defined. Also, we add a comment to reinforce that EPC and EPF libraries must be initialized before their users. Hence built-in EPC drivers, such as those of Designware, are linked after the endpoint core libraries. Finally, we add another comment to explain why obj-y has been chosen instead of obj-$(CONFIG_PCIE_DW) to parse the dwc/ sub-folder. Signed-off-by: Cyrille Pitchen Signed-off-by: Lorenzo Pieralisi

PCI: Add SPDX GPL-2.0 when no license was specified

2018-01-26T17:45:16+00:00

b24413180f56 ("License cleanup: add SPDX GPL-2.0 license identifier to files with no license") added SPDX GPL-2.0 to several PCI files that previously contained no license information. Add SPDX GPL-2.0 to all other PCI files that did not contain any license information and hence were under the default GPL version 2 license of the kernel.

x86/PCI: Remove unused HyperTransport interrupt support

2017-11-23T19:18:18+00:00

There are no in-tree callers of ht_create_irq(), the driver interface for HyperTransport interrupts, left. Remove the unused entry point and all the supporting code.

PCI: Provide Kconfig option for lockless config space accessors

2017-06-28T20:32:56+00:00

The generic PCI configuration space accessors are globally serialized via pci_lock. On larger systems this causes massive lock contention when the configuration space has to be accessed frequently. One such access pattern is the Intel Uncore performance counter unit. Provide a kernel config option which can be selected by an architecture when the low level PCI configuration space accessors in the architecture use their own serialization or can operate completely lockless.
