PCI: cadence: Add EndPoint Controller driver for Cadence PCIe controller · 37dddf14

由 Cyrille Pitchen 提交于 1月 30, 2018

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.

Fix the pci_epf_make() function so it can now bind many EPF devices to the
same EPF driver.

PCI: Add generic function to probe PCI host controllers · 49b8e3f3

由 Cyrille Pitchen 提交于 1月 30, 2018

This patchs moves generic source code from
drivers/pci/host/pci-host-common.c into drivers/pci/probe.c.

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.

PCI: Regroup all PCI related entries into drivers/pci/Makefile · 9de0eec2

由 Cyrille Pitchen 提交于 1月 30, 2018

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.

locking/barriers: Convert users of lockless_dereference() to READ_ONCE() · 3382290e

由 Will Deacon 提交于 10月 24, 2017

[ Note, this is a Git cherry-pick of the following commit:

    506458ef ("locking/barriers: Convert users of lockless_dereference() to READ_ONCE()")

  ... for easier x86 PTI code testing and back-porting. ]

READ_ONCE() now has an implicit smp_read_barrier_depends() call, so it
can be used instead of lockless_dereference() without any change in
semantics.

We'd like to use the 'PTI' acronym for 'Page Table Isolation' - free up the
namespace by renaming the <linux/pti.h> driver header to <linux/intel-pti.h>.

(Also standardize the header guard name while at it.)

net: qcom/emac: Reduce timeout for mdio read/write · 043ee1de

Currently mdio read/write takes around ~115us as the timeout
between status check is set to 100us.
By reducing the timeout to 1us mdio read/write takes ~15us to
complete. This improves the link up event response.
