Subject: [PATCH] Add secureboot pre-signing to the kernel
|
||||
|
||||
If it detects a secure boot certificate at `keys/MOK.key` and `keys/MOK.cer`,
|
||||
the kernel Makefile will automatically sign the vmlinux / bzImage file that
|
||||
gets generated, and that is then used in packaging.
|
||||
|
||||
By integrating it into the kernel build system directly, it is fully integrated
|
||||
with targets like `make deb-pkg` (opposed to `make all`, sign, `make bindeb-pkg`)
|
||||
and it gets added to every tree by the same mechanism that is used to apply the
|
||||
other surface patches anyways.

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}
|
||||

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] mwifiex: Add quirk to disable deep sleep with certain
|
||||
hardware revision
|
||||
|
||||
The 88W8897 pcie card with the hardware revision 20 apparently has a
|
||||
hardware issue where the card wakes up from deep sleep randomly and very
|
||||
often, somewhat depending on the card activity, maybe the hardware has a
|
||||
floating wakeup pin or something.
|
||||
|
||||
Those continuous wakeups prevent the card from entering host sleep when
|
||||
the computer suspends. And because the host won't answer to events from
|
||||
the card anymore while it's suspended, the firmwares internal
|
||||
powersaving state machine seems to get confused and the card can't sleep
|
||||
anymore at all after that.
|
||||
|
||||
Since we can't work around that hardware bug in the firmware, let's
|
||||
get the hardware revision string from the firmware and match it with
|
||||
known bad revisions. Then disable auto deep sleep for those revisions,
|
||||
which makes sure we no longer get those spurious wakeups.

Subject: [PATCH] mwifiex: Ignore BTCOEX events from the firmware
|
||||
|
||||
The firmware of the pcie 88W8897 chip sends those events very
|
||||
unreliably, which means we sometimes end up actually capping the window
|
||||
size while bluetooth is disabled, artifically limiting wifi speeds even
|
||||
though it's not needed.
|
||||
|
||||
Since we can't fix the firmware, let's just ignore those events, it
|
||||
seems that the Windows driver also doesn't change the rx/tx block ack
|
||||
buffer sizes when bluetooth gets enabled or disabled, so this is
|
||||
consistent with the Windows driver.

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] platform/surface: gpe: Add support for Surface Pro 8
|
||||
|
||||
The new Surface Pro 8 uses GPEs for lid events as well. Add an entry for
|
||||
that so that the lid can be used to wake the device. Note that this is a
|
||||
device with a keyboard type cover, where this acts as the "lid".

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] Input: soc_button_array - add support for Microsoft Surface 3
|
||||
(MSHW0028) buttons
|
||||
|
||||
The drivers/platform/surface/surface3_button.c code is alsmost a 1:1 copy
|
||||
of the soc_button_array code.
|
||||
|
||||
The only big difference is that it binds to an i2c_client rather then to
|
||||
a platform_device. The cause of this is the ACPI resources for the MSHW0028
|
||||
device containing a bogus I2cSerialBusV2 resource which causes the kernel
|
||||
to instantiate an i2c_client for it instead of a platform_device.
|
||||
|
||||
Add "MSHW0028" to the ignore_serial_bus_ids[] list in drivers/apci/scan.c,
|
||||
so that a platform_device will be instantiated and add support for
|
||||
the MSHW0028 HID to soc_button_array.
|
||||
|
||||
This fully replaces surface3_button, which will be removed in a separate
|
||||
commit (since it binds to the now no longer created i2c_client it no
|
||||
longer does anyyhing after this commit).
|
||||
|
||||
Note the MSHW0028 id is used by Microsoft to describe the tablet buttons on
|
||||
both the Surface 3 and the Surface 3 Pro and the actual API/implementation
|
||||
for the Surface 3 Pro is quite different. The changes in this commit should
|
||||
not impact the separate surfacepro3_button driver:
|
||||
|
||||
1. Because of the bogus I2cSerialBusV2 resource problem that driver binds
|
||||
to the acpi_device itself, so instantiating a platform_device instead of
|
||||
an i2c_client does not matter.
|
||||
|
||||
2. The soc_button_array driver will not bind to the MSHW0028 device on
|
||||
the Surface 3 Pro, because it has no GPIO resources.

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] acpi/battery: Add device HID and quirk for Microsoft Surface
|
||||
Go 3
|
||||
|
||||
For some reason, the Microsoft Surface Go 3 uses the standard ACPI
|
||||
interface for battery information, but does not use the standard PNP0C0A
|
||||
HID. Instead it uses MSHW0146 as identifier. Add that ID to the driver
|
||||
as this seems to work well.
|
||||
|
||||
Additionally, the power state is not updated immediately after the AC
|
||||
has been (un-)plugged, so add the respective quirk for that.

Subject: [PATCH] ACPI: battery: Add "Not Charging" quirk for Microsoft Surface
|
||||
devices
|
||||
|
||||
Microsoft Surface devices have a limiter that sets a fixed maximum
|
||||
charge capacity for the battery. When that maximum capacity has been
|
||||
reached, charging stops. In that case, _BST returns a battery state
|
||||
field with both "charging" and "discharging" bits cleared. The battery
|
||||
driver, however, returns "unknown" as status.
|
||||
|
||||
This seems to be the same behavior as observed on the ThinkPads, so
|
||||
let's use the same quirk to handle that as well.

||||

||||

|
||||
For what it's worth, I don't think the ACPI spec explicitly states that
|
||||
any of the status bits need to be set, or that there are only the
|
||||
"charging" and "discharging" states. As far as I can tell, ACPI only
|
||||
states:
|
||||
|
||||
Notice that the Charging bit and the Discharging bit are mutually
|
||||
exclusive and must not both be set at the same time. Even in
|
||||
critical state, hardware should report the corresponding
|
||||
charging/discharging state.
|
||||
|
||||
But that does not exclude the case that no bit is set. So, strictly
|
||||
going by spec, I don't think it's necessary to put all of this behind a
|
||||
quirk.
