Subject: [PATCH] pci: Enable overrides for missing ACS capabilities (4.18)
This an updated version of Alex Williamson's patch from:
https://lkml.org/lkml/2013/5/30/513
Original commit message follows:
---
PCIe ACS (Access Control Services) is the PCIe 2.0+ feature that
allows us to control whether transactions are allowed to be redirected
in various subnodes of a PCIe topology. For instance, if two
endpoints are below a root port or downsteam switch port, the
downstream port may optionally redirect transactions between the
devices, bypassing upstream devices. The same can happen internally
on multifunction devices. The transaction may never be visible to the
upstream devices.
One upstream device that we particularly care about is the IOMMU. If
a redirection occurs in the topology below the IOMMU, then the IOMMU
cannot provide isolation between devices. This is why the PCIe spec
encourages topologies to include ACS support. Without it, we have to
assume peer-to-peer DMA within a hierarchy can bypass IOMMU isolation.
Unfortunately, far too many topologies do not support ACS to make this
a steadfast requirement. Even the latest chipsets from Intel are only
sporadically supporting ACS. We have trouble getting interconnect
vendors to include the PCIe spec required PCIe capability, let alone
suggested features.
Therefore, we need to add some flexibility. The pcie_acs_override=
boot option lets users opt-in specific devices or sets of devices to
assume ACS support. The "downstream" option assumes full ACS support
on root ports and downstream switch ports. The "multifunction"
option assumes the subset of ACS features available on multifunction
endpoints and upstream switch ports are supported. The "id:nnnn:nnnn"
option enables ACS support on devices matching the provided vendor
and device IDs, allowing more strategic ACS overrides. These options
may be combined in any order. A maximum of 16 id specific overrides
are available. It's suggested to use the most limited set of options
necessary to avoid completely disabling ACS across the topology.
Note to hardware vendors, we have facilities to permanently quirk
specific devices which enforce isolation but not provide an ACS
capability. Please contact me to have your devices added and save
your customers the hassle of this boot option.
