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.
/sys/devices/virtual/dmi/id/board_name:Surface 3
/sys/devices/virtual/dmi/id/board_vendor:Microsoft Corporation

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] 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] 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] 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] platform/surface: surfacepro3_button: don't load on amd
variant
The AMD variant of the Surface Laptop report 0 for their OEM platform
revision. The Surface devices that require the surfacepro3_button
driver do not have the _DSM that gets the OEM platform revision. If the
method does not exist, load surfacepro3_button.

Subject: [PATCH] USB: quirks: Add USB_QUIRK_DELAY_INIT for Surface Go 3
Type-Cover
The touchpad on the Type-Cover of the Surface Go 3 is sometimes not
being initialized properly. Apply USB_QUIRK_DELAY_INIT to fix this
issue.
More specifically, the device in question is a fairly standard modern
touchpad with pointer and touchpad input modes. During setup, the device
needs to be switched from pointer- to touchpad-mode (which is done in
hid-multitouch) to fully utilize it as intended. Unfortunately, however,
this seems to occasionally fail silently, leaving the device in
pointer-mode. Applying USB_QUIRK_DELAY_INIT seems to fix this.

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] PCI: Add quirk to prevent calling shutdown mehtod
Work around buggy EFI firmware: On some Microsoft Surface devices
(Surface Pro 9 and Surface Laptop 5) the EFI ResetSystem call with
EFI_RESET_SHUTDOWN doesn't function properly. Instead of shutting the
system down, it returns and the system stays on.
It turns out that this only happens after PCI shutdown callbacks ran for
specific devices. Excluding those devices from the shutdown process
makes the ResetSystem call work as expected.
TODO: Maybe we can find a better way or the root cause of this?

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: allow usage of acpi_tad on HW-reduced platforms
The specification [1] allows so-called HW-reduced platforms,
which do not implement everything, especially the wakeup related stuff.
In that case, it is still usable as a RTC. This is helpful for [2]
and [3], which is about a device with no other working RTC,
but it does have an HW-reduced TAD, which can be used as a RTC instead.
