Subject: [PATCH] (surface3-oemb) add DMI matches for Surface 3 with broken DMI
|
||||||
|
table
|
||||||
|
|
||||||
|
On some Surface 3, the DMI table gets corrupted for unknown reasons
|
||||||
|
and breaks existing DMI matching used for device-specific quirks.
|
||||||
|
|
||||||
|
This commit adds the (broken) DMI data into dmi_system_id tables used
|
||||||
|
for quirks so that each driver can enable quirks even on the affected
|
||||||
|
systems.
|
||||||
|
|
||||||
|
On affected systems, DMI data will look like this:
|
||||||
|
$ grep . /sys/devices/virtual/dmi/id/{bios_vendor,board_name,board_vendor,\
|
||||||
|
chassis_vendor,product_name,sys_vendor}
|
||||||
|
/sys/devices/virtual/dmi/id/bios_vendor:American Megatrends Inc.
|
||||||
|
/sys/devices/virtual/dmi/id/board_name:OEMB
|
||||||
|
/sys/devices/virtual/dmi/id/board_vendor:OEMB
|
||||||
|
/sys/devices/virtual/dmi/id/chassis_vendor:OEMB
|
||||||
|
/sys/devices/virtual/dmi/id/product_name:OEMB
|
||||||
|
/sys/devices/virtual/dmi/id/sys_vendor:OEMB
|
||||||
|
|
||||||
|
Expected:
|
||||||
|
$ grep . /sys/devices/virtual/dmi/id/{bios_vendor,board_name,board_vendor,\
|
||||||
|
chassis_vendor,product_name,sys_vendor}
|
||||||
|
/sys/devices/virtual/dmi/id/bios_vendor:American Megatrends Inc.
|
||||||

|
||||||

Subject: [PATCH] mwifiex: pcie: add reset_wsid quirk for Surface 3
|
||||||
|
|
||||||
|
This commit adds reset_wsid quirk and uses this quirk for Surface 3 on
|
||||||
|
card reset.
|
||||||
|
|
||||||
|
To reset mwifiex on Surface 3, it seems that calling the _DSM method
|
||||||
|
exists in \_SB.WSID [1] device is required.
|
||||||
|
|
||||||
|
On Surface 3, calling the _DSM method removes/re-probes the card by
|
||||||
|
itself. So, need to place the reset function before performing FLR and
|
||||||
|
skip performing any other reset-related works.
|
||||||
|
|
||||||
|
Note that Surface Pro 3 also has the WSID device [2], but it seems to need
|
||||||
|
more work. This commit only supports Surface 3 yet.

Subject: [PATCH] mwifiex: pcie: (OEMB) add quirk for Surface 3 with broken DMI
|
||||||
|
table
|
||||||
|
|
||||||
|
(made referring to http://git.osdn.net/view?p=android-x86/kernel.git;a=commitdiff;h=18e2e857c57633b25b3b4120f212224a108cd883)
|
||||||
|
|
||||||
|
On some Surface 3, the DMI table gets corrupted for unknown reasons
|
||||||
|
and breaks existing DMI matching used for device-specific quirks.
|
||||||
|
|
||||||
|
This commit adds the (broken) DMI info for the affected Surface 3.
|
||||||
|
|
||||||
|
On affected systems, DMI info will look like this:
|
||||||
|
$ grep . /sys/devices/virtual/dmi/id/{bios_vendor,board_name,board_vendor,\
|
||||||
|
chassis_vendor,product_name,sys_vendor}
|
||||||
|
/sys/devices/virtual/dmi/id/bios_vendor:American Megatrends Inc.
|
||||||
|
/sys/devices/virtual/dmi/id/board_name:OEMB
|
||||||
|
/sys/devices/virtual/dmi/id/board_vendor:OEMB
|
||||||
|
/sys/devices/virtual/dmi/id/chassis_vendor:OEMB
|
||||||
|
/sys/devices/virtual/dmi/id/product_name:OEMB
|
||||||
|
/sys/devices/virtual/dmi/id/sys_vendor:OEMB
|
||||||
|
|
||||||
|
Expected:
|
||||||
|
$ grep . /sys/devices/virtual/dmi/id/{bios_vendor,board_name,board_vendor,\
|
||||||
|
chassis_vendor,product_name,sys_vendor}

Subject: [PATCH] mwifiex: pcie: disable bridge_d3 for Surface gen4+
|
||||||
|
|
||||||
|
Currently, mwifiex fw will crash after suspend on recent kernel series.
|
||||||
|
On Windows, it seems that the root port of wifi will never enter D3 state
|
||||||
|
(stay on D0 state). And on Linux, disabling the D3 state for the
|
||||||
|
bridge fixes fw crashing after suspend.
|
||||||
|
|
||||||
|
This commit disables the D3 state of root port on driver initialization
|
||||||
|
and fixes fw crashing after suspend.

Subject: [PATCH] mwifiex: Add quirk resetting the PCI bridge on MS Surface
|
||||||
|
devices
|
||||||
|
|
||||||
|
The most recent firmware of the 88W8897 card reports a hardcoded LTR
|
||||||
|
value to the system during initialization, probably as an (unsuccessful)
|
||||||
|
attempt of the developers to fix firmware crashes. This LTR value
|
||||||
|
prevents most of the Microsoft Surface devices from entering deep
|
||||||
|
powersaving states (either platform C-State 10 or S0ix state), because
|
||||||
|
the exit latency of that state would be higher than what the card can
|
||||||
|
tolerate.
|
||||||
|
|
||||||
|
Turns out the card works just the same (including the firmware crashes)
|
||||||
|
no matter if that hardcoded LTR value is reported or not, so it's kind
|
||||||
|
of useless and only prevents us from saving power.
|
||||||
|
|
||||||
|
To get rid of those hardcoded LTR reports, it's possible to reset the
|
||||||
|
PCI bridge device after initializing the cards firmware. I'm not exactly
|
||||||
|
sure why that works, maybe the power management subsystem of the PCH
|
||||||
|
resets its stored LTR values when doing a function level reset of the
|
||||||
|
bridge device. Doing the reset once after starting the wifi firmware
|
||||||
|
works very well, probably because the firmware only reports that LTR
|
||||||
|
value a single time during firmware startup.

Subject: [PATCH] Bluetooth: btusb: Lower passive lescan interval on Marvell
|
||||||
|
88W8897
|
||||||
|
|
||||||
|
The Marvell 88W8897 combined wifi and bluetooth card (pcie+usb version)
|
||||||
|
is used in a lot of Microsoft Surface devices, and all those devices
|
||||||
|
suffer from very low 2.4GHz wifi connection speeds while bluetooth is
|
||||||
|
enabled. The reason for that is that the default passive scanning
|
||||||
|
interval for Bluetooth Low Energy devices is quite high in Linux
|
||||||
|
(interval of 60 msec and scan window of 30 msec, see hci_core.c), and
|
||||||
|
the Marvell chip is known for its bad bt+wifi coexisting performance.
|
||||||
|
|
||||||
|
So decrease that passive scan interval and make the scan window shorter
|
||||||
|
on this particular device to allow for spending more time transmitting
|
||||||
|
wifi signals: The new scan interval is 250 msec (0x190 * 0.625 msec) and
|
||||||
|
the new scan window is 6.25 msec (0xa * 0,625 msec).
|
||||||
|
|
||||||
|
This change has a very large impact on the 2.4GHz wifi speeds and gets
|
||||||
|
it up to performance comparable with the Windows driver, which seems to
|
||||||
|
apply a similar quirk.
|
||||||
|
|
||||||
|
The interval and window length were tested and found to work very well
|
||||||
|
with a lot of Bluetooth Low Energy devices, including the Surface Pen, a
|
||||||
|
Bluetooth Speaker and two modern Bluetooth headphones. All devices were
|
||||||
|
discovered immediately after turning them on. Even lower values were
|
||||||
|
also tested, but they introduced longer delays until devices get
|
||||||
|
discovered.

Subject: [PATCH] mwifiex: Use non-posted PCI register writes
|
||||||
|
|
||||||
|
On the 88W8897 card it's very important the TX ring write pointer is
|
||||||
|
updated correctly to its new value before setting the TX ready
|
||||||
|
interrupt, otherwise the firmware appears to crash (probably because
|
||||||
|
it's trying to DMA-read from the wrong place).
|
||||||
|
|
||||||
|
Since PCI uses "posted writes" when writing to a register, it's not
|
||||||
|
guaranteed that a write will happen immediately. That means the pointer
|
||||||
|
might be outdated when setting the TX ready interrupt, leading to
|
||||||
|
firmware crashes especially when ASPM L1 and L1 substates are enabled
|
||||||
|
(because of the higher link latency, the write will probably take
|
||||||
|
longer).
|
||||||
|
|
||||||
|
So fix those firmware crashes by always forcing non-posted writes. We do
|
||||||
|
that by simply reading back the register after writing it, just as a lot
|
||||||
|
of other drivers do.
|
||||||
|
|
||||||
|
There are two reproducers that are fixed with this patch:
|
||||||
|
|
||||||
|
1) During rx/tx traffic and with ASPM L1 substates enabled (the enabled
|
||||||
|
substates are platform dependent), the firmware crashes and eventually a
|
||||||
|
command timeout appears in the logs. That crash is fixed by using a
|
||||||
|
non-posted write in mwifiex_pcie_send_data().
|
||||||
|
|
||||||
|
2) When sending lots of commands to the card, waking it up from sleep in
|
||||||
|
very quick intervals, the firmware eventually crashes. That crash
|
||||||
|
appears to be fixed by some other non-posted write included here.

Subject: [PATCH] ath10k: Add module parameters to override board files
|
||||||
|
|
||||||
|
Some Surface devices, specifically the Surface Go and AMD version of the
|
||||||
|
Surface Laptop 3 (wich both come with QCA6174 WiFi chips), work better
|
||||||
|
with a different board file, as it seems that the firmeware included
|
||||||
|
upstream is buggy.
|
||||||
|
|
||||||
|
As it is generally not a good idea to randomly overwrite files, let
|
||||||
|
alone doing so via packages, we add module parameters to override those
|
||||||
|
file names in the driver. This allows us to package/deploy the override
|
||||||
|
via a modprobe.d config.

Subject: [PATCH] i2c: acpi: Implement RawBytes read access
|
||||||
|
|
||||||
|
Microsoft Surface Pro 4 and Book 1 devices access the MSHW0030 I2C
|
||||||
|
device via a generic serial bus operation region and RawBytes read
|
||||||
|
access. On the Surface Book 1, this access is required to turn on (and
|
||||||
|
off) the discrete GPU.
|
||||||
|
|
||||||
|
Multiple things are to note here:
|
||||||
|
|
||||||
|
a) The RawBytes access is device/driver dependent. The ACPI
|
||||||
|
specification states:
|
||||||
|
|
||||||
|
> Raw accesses assume that the writer has knowledge of the bus that
|
||||||
|
> the access is made over and the device that is being accessed. The
|
||||||
|
> protocol may only ensure that the buffer is transmitted to the
|
||||||
|
> appropriate driver, but the driver must be able to interpret the
|
||||||
|
> buffer to communicate to a register.
|
||||||
|
|
||||||
|
Thus this implementation may likely not work on other devices
|
||||||
|
accessing I2C via the RawBytes accessor type.
|
||||||
|
|
||||||
|
b) The MSHW0030 I2C device is an HID-over-I2C device which seems to
|
||||||
|
serve multiple functions:
|
||||||
|
|
||||||
|
1. It is the main access point for the legacy-type Surface Aggregator
|
||||||
|
Module (also referred to as SAM-over-HID, as opposed to the newer
|
||||||
|
SAM-over-SSH/UART). It has currently not been determined on how
|
||||||
|
support for the legacy SAM should be implemented. Likely via a
|
||||||
|
custom HID driver.
|
||||||
|
|
||||||
|
2. It seems to serve as the HID device for the Integrated Sensor Hub.
|
||||||
|
This might complicate matters with regards to implementing a
|
||||||
|
SAM-over-HID driver required by legacy SAM.
|
||||||
|
|
||||||
|
In light of this, the simplest approach has been chosen for now.
|
||||||
|
However, it may make more sense regarding breakage and compatibility to
|
||||||
|
either provide functionality for replacing or enhancing the default
|
||||||
|
operation region handler via some additional API functions, or even to
|
||||||
|
completely blacklist MSHW0030 from the I2C core and provide a custom
|
||||||
|
driver for it.
|
||||||
|
|
||||||
|
Replacing/enhancing the default operation region handler would, however,
|
||||||
|
either require some sort of secondary driver and access point for it,
|
||||||
|
from which the new API functions would be called and the new handler
|
||||||
|
(part) would be installed, or hard-coding them via some sort of
|
||||||
|
quirk-like interface into the I2C core.

Subject: [PATCH] platform/surface: Add driver for Surface Book 1 dGPU switch
|
||||||
|
|
||||||
|
Add driver exposing the discrete GPU power-switch of the Microsoft
|
||||||
|
Surface Book 1 to user-space.
|
||||||
|
|
||||||
|
On the Surface Book 1, the dGPU power is controlled via the Surface
|
||||||
|
System Aggregator Module (SAM). The specific SAM-over-HID command for
|
||||||
|
this is exposed via ACPI. This module provides a simple driver exposing
|
||||||
|
the ACPI call via a sysfs parameter to user-space, so that users can
|
||||||
|
easily power-on/-off the dGPU.

Subject: [PATCH] Input: soc_button_array - support AMD variant Surface devices
|
||||||
|
|
||||||
|
The power button on the AMD variant of the Surface Laptop uses the
|
||||||
|
same MSHW0040 device ID as the 5th and later generation of Surface
|
||||||
|
devices, however they report 0 for their OEM platform revision. As the
|
||||||
|
_DSM does not exist on the devices requiring special casing, check for
|
||||||
|
the existance of the _DSM to determine if soc_button_array should be
|
||||||
|
loaded.
|
||||||
|
|
||||||

Subject: [PATCH] hid/multitouch: Turn off Type Cover keyboard backlight when
|
||||||
|
suspending
|
||||||
|
|
||||||
|
The Type Cover for Microsoft Surface devices supports a special usb
|
||||||
|
control request to disable or enable the built-in keyboard backlight.
|
||||||
|
On Windows, this request happens when putting the device into suspend or
|
||||||
|
resuming it, without it the backlight of the Type Cover will remain
|
||||||
|
enabled for some time even though the computer is suspended, which looks
|
||||||
|
weird to the user.
|
||||||
|
|
||||||
|
So add support for this special usb control request to hid-multitouch,
|
||||||
|
which is the driver that's handling the Type Cover.
|
||||||
|
|
||||||
|
The reason we have to use a pm_notifier for this instead of the usual
|
||||||
|
suspend/resume methods is that those won't get called in case the usb
|
||||||
|
device is already autosuspended.
|
||||||
|
|
||||||
|
Also, if the device is autosuspended, we have to briefly autoresume it
|
||||||
|
in order to send the request. Doing that should be fine, the usb-core
|
||||||
|
driver does something similar during suspend inside choose_wakeup().
|
||||||
|
|
||||||
|
To make sure we don't send that request to every device but only to
|
||||||
|
devices which support it, add a new quirk
|
||||||
|
MT_CLS_WIN_8_MS_SURFACE_TYPE_COVER to hid-multitouch. For now this quirk
|
||||||
|
is only enabled for the usb id of the Surface Pro 2017 Type Cover, which
|
||||||
|
is where I confirmed that it's working.

Subject: [PATCH] hid/multitouch: Add support for surface pro type cover tablet
|
||||||
|
switch
|
||||||
|
|
||||||
|
The Surface Pro Type Cover has several non standard HID usages in it's
|
||||||
|
hid report descriptor.
|
||||||
|
I noticed that, upon folding the typecover back, a vendor specific range
|
||||||
|
of 4 32 bit integer hid usages is transmitted.
|
||||||
|
Only the first byte of the message seems to convey reliable information
|
||||||
|
about the keyboard state.
|
||||||
|
|
||||||
|
0x22 => Normal (keys enabled)
|
||||||
|
0x33 => Folded back (keys disabled)
|
||||||
|
0x53 => Rotated left/right side up (keys disabled)
|
||||||
|
0x13 => Cover closed (keys disabled)
|
||||||
|
0x43 => Folded back and Tablet upside down (keys disabled)
|
||||||
|
This list may not be exhaustive.
|
||||||
|
|
||||||
|
The tablet mode switch will be disabled for a value of 0x22 and enabled
|
||||||
|
on any other value.
|
||||||
|
|
||||||
|

Subject: [PATCH] HID: hid-input: add Surface Go battery quirk
|
||||||
|
|
||||||
|
Similar to the Surface Go (1), the (Elantech) touchscreen/digitizer in
|
||||||
|
the Surface Go 2 mistakenly reports the battery of the stylus. Instead
|
||||||
|
of over the touchsreen device, battery information is provided via
|
||||||
|
bluetooth and the touchscreen device reports an empty battery.
|
||||||
|
|
||||||
|
Apply the HID_BATTERY_QUIRK_IGNORE quirk to to ignore this battery and
|
||||||
|
prevent the erroneous low battery warnings.

Subject: [PATCH] ACPI: delay enumeration of devices with a _DEP pointing to an
|
||||||
|
INT3472 device
|
||||||
|
|
||||||
|
The clk and regulator frameworks expect clk/regulator consumer-devices
|
||||||
|
to have info about the consumed clks/regulators described in the device's
|
||||||
|
fw_node.
|
||||||
|
|
||||||
|
To work around cases where this info is not present in the firmware tables,
|
||||||
|
which is often the case on x86/ACPI devices, both frameworks allow the
|
||||||
|
provider-driver to attach info about consumers to the clks/regulators
|
||||||
|
when registering these.
|
||||||
|
|
||||||
|
This causes problems with the probe ordering wrt drivers for consumers
|
||||||
|
of these clks/regulators. Since the lookups are only registered when the
|
||||||
|
provider-driver binds, trying to get these clks/regulators before then
|
||||||
|
results in a -ENOENT error for clks and a dummy regulator for regulators.
|
||||||
|
|
||||||
|
One case where we hit this issue is camera sensors such as e.g. the OV8865
|
||||||
|
sensor found on the Microsoft Surface Go. The sensor uses clks, regulators
|
||||||
|
and GPIOs provided by a TPS68470 PMIC which is described in an INT3472
|
||||||
|
ACPI device. There is special platform code handling this and setting
|
||||||
|
platform_data with the necessary consumer info on the MFD cells
|
||||||
|
instantiated for the PMIC under: drivers/platform/x86/intel/int3472.
|
||||||
|
|
||||||
|
For this to work properly the ov8865 driver must not bind to the I2C-client
|
||||||
|
for the OV8865 sensor until after the TPS68470 PMIC gpio, regulator and
|
||||||
|
clk MFD cells have all been fully setup.
|
||||||
|
|
||||||
|
The OV8865 on the Microsoft Surface Go is just one example, all X86
|
||||||
|
devices using the Intel IPU3 camera block found on recent Intel SoCs
|
||||||
|
have similar issues where there is an INT3472 HID ACPI-device, which
|
||||||
|
describes the clks and regulators, and the driver for this INT3472 device
|
||||||
|
must be fully initialized before the sensor driver (any sensor driver)
|
||||||
|
binds for things to work properly.
|
||||||
|
|
||||||
|
On these devices the ACPI nodes describing the sensors all have a _DEP
|
||||||
|
dependency on the matching INT3472 ACPI device (there is one per sensor).
|
||||||
|
|
||||||
|
This allows solving the probe-ordering problem by delaying the enumeration
|
||||||
|
(instantiation of the I2C-client in the ov8865 example) of ACPI-devices
|
||||||
|
which have a _DEP dependency on an INT3472 device.
|
||||||
|
|
||||||
|
The new acpi_dev_ready_for_enumeration() helper used for this is also
|
||||||
|
exported because for devices, which have the enumeration_by_parent flag
|
||||||
|
set, the parent-driver will do its own scan of child ACPI devices and
|
||||||
|
it will try to enumerate those during its probe(). Code doing this such
|
||||||
|
as e.g. the i2c-core-acpi.c code must call this new helper to ensure
|
||||||
|
that it too delays the enumeration until all the _DEP dependencies are
|
||||||
|
met on devices which have the new honor_deps flag set.

Subject: [PATCH] iommu: intel-ipu: use IOMMU passthrough mode for Intel IPUs
|
||||||
|
|
||||||
|
Intel IPU(Image Processing Unit) has its own (IO)MMU hardware,
|
||||||
|
The IPU driver allocates its own page table that is not mapped
|
||||||
|
via the DMA, and thus the Intel IOMMU driver blocks access giving
|
||||||
|
this error: DMAR: DRHD: handling fault status reg 3 DMAR:
|
||||||
|
[DMA Read] Request device [00:05.0] PASID ffffffff
|
||||||
|
fault addr 76406000 [fault reason 06] PTE Read access is not set
|
||||||
|
As IPU is not an external facing device which is not risky, so use
|
||||||
|
IOMMU passthrough mode for Intel IPUs.

Subject: [PATCH] media: i2c: Add driver for DW9719 VCM
|
||||||
|
|
||||||
|
Add a driver for the DW9719 VCM. The driver creates a v4l2 subdevice
|
||||||
|
and registers a control to set the desired focus.

Subject: [PATCH] media: ipu3-cio2: Move functionality from .complete() to
|
||||||
|
.bound()
|
||||||
|
|
||||||
|
Creating links and registering subdev nodes during the .complete()
|
||||||
|
callback has the unfortunate effect of preventing all cameras that
|
||||||
|
connect to a notifier from working if any one of their drivers fails
|
||||||
|
to probe. Moving the functionality from .complete() to .bound() allows
|
||||||
|
those camera sensor drivers that did probe correctly to work regardless.

Subject: [PATCH] media: ipu3-cio2: Re-add .complete() to ipu3-cio2
|
||||||
|
|
||||||
|
Removing the .complete() callback had some unintended consequences.
|
||||||
|
Because the VCM driver is not directly linked to the ipu3-cio2
|
||||||
|
driver .bound() never gets called for it, which means its devnode
|
||||||
|
is never created if it probes late. Because .complete() waits for
|
||||||
|
any sub-notifiers to also be complete it is captured in that call.

Subject: [PATCH] ACPI: Add quirk for Surface Laptop 4 AMD missing irq 7
|
||||||
|
override
|
||||||
|
|
||||||
|
This patch is the work of Thomas Gleixner <tglx@linutronix.de> and is
|
||||||
|
copied from:
|
||||||
|
https://lore.kernel.org/lkml/87lf8ddjqx.ffs@nanos.tec.linutronix.de/
|
||||||
|
|
||||||
|
This patch adds a quirk to the ACPI setup to patch in the the irq 7 pin
|
||||||
|
setup that is missing in the laptops ACPI table.
|
||||||
|
|
||||||
|
This patch was used for validation of the issue, and is not a proper
|
||||||
|
fix, but is probably a better temporary hack than continuing to probe
|
||||||
|
the Legacy PIC and run with the PIC in an unknown state.

Subject: [PATCH] ACPI: Add AMD 13" Surface Laptop 4 model to irq 7 override
|
||||||
|
quirk
|
||||||
|
|
||||||
|
The 13" version of the Surface Laptop 4 has the same problem as the 15"
|
||||||
|
version, but uses a different SKU. Add that SKU to the quirk as well.
