git://git.kernel.org/pub/scm/linux/kernel/git/pdx86/platform-drivers-x86
Pull another x86 platform driver fix from Hans de Goede:
"One final pdx86 fix for Tablet Mode reporting regressions (which make
the keyboard and touchpad unusable) on various Asus notebooks.
These regressions were caused by the asus-nb-wmi and the intel-vbtn
drivers both receiving recent patches to start reporting Tablet Mode /
to report it on more models.
Due to a miscommunication between Andy and me, Andy's earlier pull-req
only contained the fix for the intel-vbtn driver and not the fix for
the asus-nb-wmi code.
This fix has been tested as a downstream patch in Fedora kernels for
approx two weeks with no problems being reported"

platform/x86: asus-wmi: Fix SW_TABLET_MODE always reporting 1 on many different models
|
|
different models
Commit b0dbd97de1f1 ("platform/x86: asus-wmi: Add support for
SW_TABLET_MODE") added support for reporting SW_TABLET_MODE using the
Asus 0x00120063 WMI-device-id to see if various transformer models were
docked into their keyboard-dock (SW_TABLET_MODE=0) or if they were
being used as a tablet.
The new SW_TABLET_MODE support (naively?) assumed that non Transformer
devices would either not support the 0x00120063 WMI-device-id at all,
or would NOT set ASUS_WMI_DSTS_PRESENCE_BIT in their reply when querying
the device-id.
Unfortunately this is not true and we have received many bug reports about
this change causing the asus-wmi driver to always report SW_TABLET_MODE=1
on non Transformer devices. This causes libinput to think that these are
360 degree hinges style 2-in-1s folded into tablet-mode. Making libinput
suppress keyboard and touchpad events from the builtin keyboard and
touchpad. So effectively this causes the keyboard and touchpad to not work
on many non Transformer Asus models.
This commit fixes this by using the existing DMI based quirk mechanism in
asus-nb-wmi.c to allow using the 0x00120063 device-id for reporting
SW_TABLET_MODE on Transformer models and ignoring it on all other models.

cfae58ed681c ("platform/x86: intel-vbtn: Only blacklist SW_TABLET_MODE
on the 9 / "Laptop" chasis-type")
1fac39fd0316 ("platform/x86: intel-vbtn: Also handle tablet-mode switch on
"Detachable" and "Portable" chassis-types")
Enabled reporting of SW_TABLET_MODE on more devices since the vbtn ACPI
interface is used by the firmware on some of those devices to report this.
Testing has shown that unconditionally enabling SW_TABLET_MODE reporting
on all devices with a chassis type of 8 ("Portable") or 10 ("Notebook")
which support the VGBS method is a very bad idea.
Many of these devices are normal laptops (non 2-in-1) models with a VGBS
which always returns 0, which we translate to SW_TABLET_MODE=1. This in
turn causes userspace (libinput) to suppress events from the builtin
keyboard and touchpad, making the laptop essentially unusable.
Since the problem of wrongly reporting SW_TABLET_MODE=1 in combination
with libinput, leads to a non-usable system. Where as OTOH many people will
not even notice when SW_TABLET_MODE is not being reported, this commit
changes intel_vbtn_has_switches() to use a DMI based allow-list.
The new DMI based allow-list matches on the 31 ("Convertible") and
32 ("Detachable") chassis-types, as these clearly are 2-in-1s and
so far if they support the intel-vbtn ACPI interface they all have
properly working SW_TABLET_MODE reporting.
Besides these 2 generic matches, it also contains model specific matches
for 2-in-1 models which use a different chassis-type and which are known
to have properly working SW_TABLET_MODE reporting.
This has been tested on the following 2-in-1 devices:
Dell Venue 11 Pro 7130 vPro
HP Pavilion X2 10-p002nd
HP Stream x360 Convertible PC 11
Medion E1239T

A struct device is a dynamic structure, with reference counting.
"Tricking" the kernel to make a dynamic structure static, by working
around the driver core release detection logic, is not nice.
Because of this, this code has been used as an example for others on
"how to do things", which is just about the worst thing possible to have
happen.
Fix this all up by making the platform device dynamic and providing a
real release function.

Pavilion 11 x360
Commit cfae58ed681c ("platform/x86: intel-vbtn: Only blacklist
SW_TABLET_MODE on the 9 / "Laptop" chasis-type") restored SW_TABLET_MODE
reporting on the HP stream x360 11 series on which it was previously broken
by commit de9647efeaa9 ("platform/x86: intel-vbtn: Only activate tablet
mode switch on 2-in-1's").
It turns out that enabling SW_TABLET_MODE reporting on devices with a
chassis-type of 10 ("Notebook") causes SW_TABLET_MODE to always report 1
at boot on the HP Pavilion 11 x360, which causes libinput to disable the
kbd and touchpad.
The HP Pavilion 11 x360's ACPI VGBS method sets bit 4 instead of bit 6 when
NOT in tablet mode at boot. Inspecting all the DSDTs in my DSDT collection
shows only one other model, the Medion E1239T ever setting bit 4 and it
always sets this together with bit 6.
So lets treat bit 4 as a second bit which when set indicates the device not
being in tablet-mode, as we already do for bit 6.
While at it also prefix all VGBS constant defines with "VGBS_".

The WMI INIT method on for some reason turns on the camera LED on these
2-in-1s, without the WMI interface allowing further control over the LED.
To fix this commit b5f7311d3a2e ("platform/x86: asus-nb-wmi: Do not load
on Asus T100TA and T200TA") added a blacklist with these 2 models on it
since the WMI driver did not add any extra functionality to these models.
Recently I've been working on making more 2-in-1 models report their
tablet-mode (SW_TABLET_MODE) to userspace; and I've found that these 2
Asus models report this through WMI. This commit reverts the adding
of the blacklist, so that the Asus WMI driver can be used on these
models to report their tablet-mode. I have another patch fixing the LED
issue in a different manner.
Note this is the second time the we revert the adding of the
asus_nb_wmi_blacklist. It was reverted before in commit:
aab9e7896ec9 ("platform/x86: asus-nb-wmi: Revert "Do not load on Asus
T100TA and T200TA")"
But some how (accidentally re-applying of the patch?) it got re-added
again in commit 3bd12da7f50b ("platform/x86: asus-nb-wmi: Do not load
on Asus T100TA and T200TA"), so now we need to revert it again.

As part of this update, change the error handling inside
cros_ec_get_sensor_count() such that the legacy LPC interface is tried
on all error values, not just when msg->result != EC_RESULT_SUCCESS.
Note that there is a slight change in API in cros_ec_get_sensor_count():
it will return a negative number of sensors when there are no sensors
on arm platform when MOTIONSENSE_CMD_DUMP is not supported (typical for
sensorless chromebook) instead of 0. However, this is not a problem when
probing the EC as we ignore errors only looking for cros_ec_get_sensor_count()
returning a positive number of sensors.

KEY_SELECTIVE_SCREENSHOT
Commit 696c6523ec8f ("platform/x86: thinkpad_acpi: add mapping for new
hotkeys") added support for a bunch of new hotkeys, but the
clipping/snipping tool hotkey got ignored because there was no good
key-code to map it to.
Recently a new KEY_SELECTIVE_SCREENSHOT keycode was added by commit
3b059da9835c ("Input: allocate keycode for "Selective Screenshot" key")
quoting from the commit message:
"New Chrome OS keyboards have a "snip" key that is basically a selective
screenshot (allows a user to select an area of screen to be copied).
Allocate a keycode for it."
Support for this "snip" key seems like it is also a good match for the
clipping/snipping tool hotkey, so map this hotkey to the new
KEY_SELECTIVE_SCREENSHOT key-code.

New Lenovo Thinkpad models, e.g. the X1 Carbon 8th gen and the new T14 gen1
models have 3 new symbols / shortcuts on their F9-F11 keys (and the
thinkpad_acpi driver receives 3 new hkey events for these):
F9: Has a symbol resembling a rectangular speech balloon, the manual says
the hotkey functions shows or hides the notification center
F10: Has a symbol of a telephone horn which has been picked up from the
receiver, the manual says: "Answer incoming calls"
F11: Has a symbol of a telephone horn which is resting on the receiver,
the manual says: "Decline incoming calls"
And these Thinkpad models also send a new 0x1316 hkey events when the
Fn + right Shift key-combo is pressed.
This commit adds support for these 4 new hkey events.

As per USB Type-C Spec R2.0 section 4.5.1.2 (Connecting Sources and Sinks)
and section 4.5.2.2 (Connection State Machine Requirements), the typical
flow for configuring a device connected to a typeC port is as below:
1. Source/sink detection
2. Orientation
3. Data role
4. VCONN
5. VBUS (USB Type-C currents)
6. The connector is now configured. We can start the PD communication
that should lead into configuration of the mux if we enter a mode.
But in existing code data role was set after the connector and mux are
already configured. So fix this by following the spec to set the data
role before the connector and mux are configured.

Currently depending upon the data role i.e. UFP(0) or DFP(1) is sent.
This eventually translates to USB_ROLE_NONE in case of UFP and

The EC reports a variety of error codes. Most of those, with the exception
of EC_RES_INVALID_VERSION, are converted to -EPROTO. As result, the actual
EC error code gets lost. Introduce cros_ec_map_error() to map EC error
codes to Linux error codes, and use it in cros_ec_cmd_xfer_status() to
report more meaningful errors to the caller. With this change, callers of
cros_ec_cmd_xfer_status() can implement a more distinguished action without
having to rely on the EC error code. At the same time, debugging is improved
in situations where the Linux error code is reported to userspace and/or in
the kernel log.

-ENOTSUPP is not a SUSV4 error code and should not be used. Use
-ENOPROTOOPT instead to report EC_RES_INVALID_VERSION responses
from the EC. This matches match the NFS response for unsupported

Since commit c5cd2b47b203 ("platform/chrome: cros_ec_proto: Report command
not supported") we can no longer assume that cros_ec_cmd_xfer_status()
reports -EPROTO for all errors returned by the EC itself. A follow-up
patch will change cros_ec_cmd_xfer_status() to report additional errors
reported by the EC as distinguished Linux error codes.
Prepare for this change by always reporting both the Linux error code
and the EC error code in sysfs attributes.

which works for it since the legacy virtio native types.
This will break if it ever needs to support modern virtio,

Since this is a legacy only device, fix it up using

EC_CMD_HOST_EVENT_GET_WAKE_MASK
As with cros_ec_cmd_xfer_status(), etc., it's not enough to simply check
for the return status of send_command() -- that only covers transport or
other similarly-fatal errors. One must also check the ->result field, to
see whether the command really succeeded. If not, we can't use the data
it returns.
The caller of cros_ec_get_host_event_wake_mask() ignores this, and so
for example, on EC's where the command is not implemented, we're using
junk (or in practice, all zeros) for our wake-mask. We should be using a
non-zero default (currently, it's supposed to be all-1's).
Fix this by checking the ->result field and returning -EPROTO for
errors.
I might label this as fixing commit 29d99b966d60 ("cros_ec: Don't signal
wake event for non-wake host events"), except that this fix alone
actually may make things worse, as it now allows for a lot more spurious
wakeups. The patch "platform/chrome: cros_ec_proto: ignore battery/AC
wakeups on old ECs" helps to mitigate this.

ECs that don't implement EC_CMD_HOST_EVENT_GET_WAKE_MASK should still
have some reasonable default mask -- otherwise, they'll treat a variety
of EC signals as spurious wakeups. Battery and AC events can be
especially common, for devices that have been sitting at full charge
plugged into AC for a long time, as they may cycle their charging off
and on, or their battery may start reporting failures as it ages.
Treating these as wakeups does not serve a useful purpose, and is
instead often counterproductive. And indeed, later ECs (that implement
the mask) don't include these events in their wake-mask.
Note that this patch doesn't do anything without the subsequent patch
("platform/chrome: cros_ec_proto: check for missing
EC_CMD_HOST_EVENT_GET_WAKE_MASK"), because
cros_ec_get_host_event_wake_mask() currently does not return an error if
EC_CMD_HOST_EVENT_GET_WAKE_MASK is not implemented.
Some additional notes:
While the EC typically knows not to wake the CPU for these unimportant
events once the CPU reaches a sleep state, it doesn't really have a way
to know that the CPU is "almost" asleep, unless it has support for
EC_CMD_HOST_SLEEP_EVENT. Alas, these older ECs do not support that
command either, so this solution is not 100% complete.

On some machines (nami), interrupt latency cause samples to appear
to be from the future and are pegged to the current time.
We would see samples with this pattern:
[t, t + ~5ms, t + ~10ms, t + ~10ms + 100us, t + ~10ms + 200us],
(current now) (current now)
(t is the last timestamp time)
Last 2 samples would be barely spread, causing applications to
complain.
We now spread the entire sequence. This is not great: in the example
the sensor was supposed to send samples every 5ms, it now appears to
send one every 2.5ms, but it is slightly closer to reality:
sampling time in the example above
At sensor level
1 2 3 4 5
+-----5ms-----+-----5ms-----+-----5ms-----+----5ms-----+---> t
Before, at host level
