Update v5.8 patches
Changes:
- SAM:
- Update DTX driver state after resume.
- Add DTX Documentation, misc. fixes, and cleanup.
- IPTS:
This implements a new and refined UAPI interface that should improve
stability during suspend and move some responsibility into userspace,
making the driver simpler.
It also fixes some sleep issues due to improper shutdown of the device.
Shortlog:
0a4a44c Add missing include
31ae03d Improve error handling of ipts_control_* functions

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}
|
||||

|
||||
Subject: [PATCH] platform/x86: Add Driver to set up lid GPEs on MS Surface
|
||||
device
|
||||
|
||||
Conventionally, wake-up events for a specific device, in our case the
|
||||
lid device, are managed via the ACPI _PRW field. While this does not
|
||||
seem strictly necessary based on ACPI spec, the kernel disables GPE
|
||||
wakeups to avoid non-wakeup interrupts preventing suspend by default and
|
||||
only enables GPEs associated via the _PRW field with a wake-up capable
|
||||
device. This behavior has been introduced in commit
|
||||
|
||||
f941d3e41da7f86bdb9dcc1977c2bcc6b89bfe47
|
||||
ACPI: EC / PM: Disable non-wakeup GPEs for suspend-to-idle
|
||||
|
||||
and is described in more detail in its commit message.
|
||||
|
||||
Unfortunately, on MS Surface devices, there is no _PRW field present on
|
||||
the lid device, thus no GPE is associated with it, and therefore the GPE
|
||||
responsible for sending the status-change notification to the lid gets
|
||||
disabled during suspend, making it impossible to wake the device via the
|
||||
lid.
|
||||
|
||||
This patch introduces a pseudo-device and respective driver which, based
|
||||
on some DMI matching, mark the corresponding GPE of the lid device for
|
||||
wake and enable it during suspend. The behavior of this driver models
|
||||
the behavior of the ACPI/PM core for normal wakeup GPEs, properly
|
||||
declared via the _PRW field.

Subject: [PATCH 5/7] surface-sam-over-hid
|
||||
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/x86: 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.
