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] 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] 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] 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] xhci: Fix commad ring abort, write all 64 bits to CRCR
|
||||
register.
|
||||
|
||||
Turns out some xHC controllers require all 64 bits in the CRCR register
|
||||
to be written to execute a command abort.
|
||||
|
||||
The lower 32 bits containing the command abort bit is written first.
|
||||
In case the command ring stops before we write the upper 32 bits then
|
||||
hardware may use these upper bits to set the commnd ring dequeue pointer.
|
||||
|
||||
Solve this by making sure the upper 32 bits contain a valid command
|
||||
ring dequeue pointer.
|
||||
|
||||
The original patch that only wrote the first 32 to stop the ring went
|
||||
to stable, so this fix should go there as well.

||||

||||
