Subject: [PATCH 1/2] add-acs-overrides
|
||||
|
||||
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 devicstarting

Subject: [PATCH] i915: Add module option to support VGA arbiter on HD devices

(5.19)

Subject: [PATCH 2/2] i915-vga-arbiter
|
||||
|
||||
This is an updated version of Alex Williamson's patch from:
|
||||
https://lkml.org/lkml/2014/5/9/517
|
||||
|
||||
I don't have i915 graphics, so this is completely untested.
|
||||
|
||||
Original commit message follows:
|
||||
---
|
||||
Commit 81b5c7bc found that the current VGA arbiter support in i915
|
||||
only works for ancient GMCH-based IGD devices and attempted to update
|
||||
support for newer HD devices. Unfortunately newer devices cannot
|
||||
completely opt-out of VGA arbitration like the old devices could.
|
||||
The VGA I/O space cannot be disabled internally. The only way to
|
||||
route VGA I/O elsewhere is by disabling I/O at the device PCI command
|
||||
register. This means that with commit 81b5c7bc and multiple VGA
|
||||
adapters, the VGA arbiter will report that multiple VGA devices are
|
||||
participating in arbitration, Xorg will notice this and disable DRI.
|
||||
Therefore, 81b5c7bc was reverted because DRI is more important than
|
||||
being correct.
|
||||
|
||||
There is however an actual need for i915 to correctly participate in
|
||||
VGA arbitration; VGA device assignment. If we want to use VFIO to
|
||||
assign a VGA device to a virtual machine, we need to be able to
|
||||
access the VGA resources of that device. By adding an i915 module
|
||||
option we can allow i915 to continue with its charade by default, but
|
||||
also allow an easy path for users who require working VGA arbitration.
|
||||
Hopefully Xorg can someday be taught to behave better with multiple
|
||||
VGA devices.
|
||||
|
||||
This also rolls in reverted commit 6e1b4fda, which corrected an
|
||||
ordering issue with 81b5c7bc by delaying the disabling of VGA memory
|
||||
until after vgacon->fbcon handoff.
