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. + +Signed-off-by: Mark Weiman --- .../admin-guide/kernel-parameters.txt | 8 ++ drivers/pci/quirks.c | 102 ++++++++++++++++++ 2 files changed, 110 insertions(+) diff --git a/Documentation/admin-guide/kernel-parameters.txt b/Documentation/admin-guide/kernel-parameters.txt -index 533ff5c68970..353481231683 100644 +index ff4ba249a26f..e23d259d461f 100644 --- a/Documentation/admin-guide/kernel-parameters.txt +++ b/Documentation/admin-guide/kernel-parameters.txt -@@ -3028,6 +3028,14 @@ +@@ -3019,6 +3019,14 @@ nomsi [MSI] If the PCI_MSI kernel config parameter is enabled, this kernel boot option can be used to disable the use of MSI interrupts system-wide. @@ -32,11 +71,11 @@ index 533ff5c68970..353481231683 100644 Safety option to keep boot IRQs enabled.
