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 4/4] mac80211: disable BHs/preemption in

On pre-emption enabled kernels the following print was being seen due to

missing local_bh_disable/local_bh_enable calls. mac80211 assumes that
|
||||
pre-emption is disabled in the data path.
|
||||
|
||||
BUG: using smp_processor_id() in preemptible [00000000] code: iwd/517
|
||||
caller is __ieee80211_subif_start_xmit+0x144/0x210 [mac80211]

|
||||
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.
