Subject: [PATCH 2/4] Revert "drm/i915/edp: Allow alternate fixed mode for eDP
 | 
			
		||||
 if available."
 | 
			
		||||
 | 
			
		||||
This reverts commit dc911f5bd8aacfcf8aabd5c26c88e04c837a938e.
 | 
			
		||||
 | 
			
		||||
Per the report, no matter what display mode you select with xrandr, the
 | 
			
		||||
i915 driver will always select the alternate fixed mode. For the
 | 
			
		||||
reporter this means that the display will always run at 40Hz which is
 | 
			
		||||
quite annoying. This may be due to the mode comparison.
 | 
			
		||||
 | 
			
		||||
But there are some other potential issues. The choice of alt_fixed_mode
 | 
			
		||||
seems dubious. It's the first non-preferred mode, but there are no
 | 
			
		||||
guarantees that the only difference would be refresh rate. Similarly,
 | 
			
		||||
there may be more than one preferred mode in the probed modes list, and
 | 
			
		||||
the commit changes the preferred mode selection to choose the last one
 | 
			
		||||
on the list instead of the first.
 | 
			
		||||
 | 
			
		||||
(Note that the probed modes list is the raw, unfiltered, unsorted list
 | 
			
		||||
of modes from drm_add_edid_modes(), not the pretty result after a
 | 
			
		||||
drm_helper_probe_single_connector_modes() call.)
 | 
			
		||||
 | 
			
		||||
Finally, we already have eerily similar code in place to find the
 | 
			
		||||
downclock mode for DRRS that seems like could be reused here.
 | 
			
		||||
 | 
			
		||||
Back to the drawing board.
 | 
			
		||||
 | 
			
		||||
Note: This is a hand-crafted revert due to conflicts. If it fails to
 | 
			
		||||
backport, please just try reverting the original commit directly.

Subject: [PATCH 3/4] ACPI / watchdog: Prefer iTCO_wdt always when WDAT table
 | 
			
		||||
 uses RTC SRAM
 | 
			
		||||
 | 
			
		||||
After we added quirk for Lenovo Z50-70 it turns out there are at least
 | 
			
		||||
two more systems where WDAT table includes instructions accessing RTC
 | 
			
		||||
SRAM. Instead of quirking each system separately, look for such
 | 
			
		||||
instructions in the table and automatically prefer iTCO_wdt if found.

Subject: [PATCH] pci: Enable overrides for missing ACS capabilities (4.17.14)
 | 
			
		||||
 | 
			
		||||
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.
