platform/x86: ISST: Add Grand Ridge to HPM CPU list
Commit 47ea0ddb1f ("platform/chrome: cros_ec_lpc: Separate host
command and irq disable") re-ordered the resume sequence. Before that
change, cros_ec resume sequence is:
1) Enable IRQ
2) Send resume event
3) Handle events during suspend
After commit 47ea0ddb1f ("platform/chrome: cros_ec_lpc: Separate host
command and irq disable"), cros_ec resume sequence is:
1) Enable IRQ
2) Handle events during suspend
3) Send resume event.
This re-ordering leads to delayed handling of any events queued between
items 2) and 3) with the updated sequence. Also in certain platforms, EC
skips triggering interrupt for certain events eg. mkbp events until the
resume event is received. Such events are stuck in the host event queue
indefinitely. This change puts back the original order to avoid any
delay in handling the pending events.

The original Framework Laptop 13 platform (Intel 11th, 12th, and 13th
Generation at this time) uses a Microchip embedded controller in a
standard configuration.
The newer devices in this product line--Framework Laptop 13 and 16 (AMD
Ryzen)--use a NPCX embedded controller. However, they deviate from the
configuration of ChromeOS platforms built with the NPCX EC.
* The MMIO region for EC memory begins at port 0xE00 rather than the
expected 0x900.

The cros_ec_uart_probe() function calls devm_serdev_device_open() before
it calls serdev_device_set_client_ops(). This can trigger a NULL pointer
dereference:
BUG: kernel NULL pointer dereference, address: 0000000000000000
...
Call Trace:
<TASK>
...
? ttyport_receive_buf
A simplified version of crashing code is as follows:
static inline size_t serdev_controller_receive_buf(struct serdev_controller *ctrl,
const u8 *data,
size_t count)
{
struct serdev_device *serdev = ctrl->serdev;
if (!serdev || !serdev->ops->receive_buf) // CRASH!
return 0;
return serdev->ops->receive_buf(serdev, data, count);
}
It assumes that if SERPORT_ACTIVE is set and serdev exists, serdev->ops
will also exist. This conflicts with the existing cros_ec_uart_probe()
logic, as it first calls devm_serdev_device_open() (which sets
SERPORT_ACTIVE), and only later sets serdev->ops via
serdev_device_set_client_ops().
Commit 01f95d42b8 ("platform/chrome: cros_ec_uart: fix race
condition") attempted to fix a similar race condition, but while doing
so, made the window of error for this race condition to happen much
wider.
Attempt to fix the race condition again, making sure we fully setup
before calling devm_serdev_device_open().

ACER Vivobook Flip (TP401NAS) virtual intel switch is implemented as

Device (VGBI)

Method (_STA, 0, Serialized) // _STA: Status ...
Method (VBDL, 0, Serialized)

}
Method (VGBS, 0, Serialized)
{
Return (VBDS) /* \_SB_.PCI0.SBRG.EC0_.VGBI.VBDS */
}
...
}
By default VBDS is set to 0. At boot it is set to clamshell (bit 6 set)
only after method VBDL is executed.
Since VBDL is now evaluated in the probe routine later, after the device
is registered, the retrieved value of VBDS was still 0 ("tablet mode")
when setting up the virtual switch.
Make sure to evaluate VGBS after VBDL, to ensure the
convertible boots in clamshell mode, the expected default.

This was a relatively calm development cycle. Most of changes are
rather small device-specific fixes and enhancements. The only
significant changes in ALSA core are code refactoring with the recent
cleanup infrastructure, which should bring no functionality changes.
Some highlights below:
Core:
- Lots of cleanups in ALSA core code with automatic kfree cleanup
and locking guard macros
- New ALSA core kunit test
ASoC:
- SoundWire support for AMD ACP 6.3 systems
- Support for reporting version information for AVS firmware
- Support DSPless mode for Intel Soundwire systems
- Support for configuring CS35L56 amplifiers using EFI calibration
data
- Log which component is being operated on as part of power management
trace events.
- Support for Microchip SAM9x7, NXP i.MX95 and Qualcomm WCD939x
HD- and USB-audio:
- More Cirrus HD-audio codec support
- TAS2781 HD-audio codec fixes
- Scarlett2 mixer fixes
Others:
- Enhancement of virtio driver for audio control supports
- Cleanups of legacy PM code with new macros
- Firewire sound updates

Merge tag 'thermal-6.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull thermal control updates from Rafael Wysocki:
"These mostly change the thermal core in a few ways allowing thermal
drivers to be simplified, in particular in their removal and failing
probe handling parts that are notoriously prone to errors, and
propagate the changes to several drivers.
Apart from that, support for a new platform is added (Intel Lunar
Lake-M), some bugs are fixed and some code is cleaned up, as usual.
Specifics:
- Store zone trips table and zone operations directly in struct
thermal_zone_device (Rafael Wysocki)
- Fix up flex array initialization during thermal zone device
registration (Nathan Chancellor)
- Rework writable trip points handling in the thermal core and
several drivers (Rafael Wysocki)
- Thermal core code cleanups (Dan Carpenter, Flavio Suligoi)
- Use thermal zone accessor functions in the int340x Intel thermal
driver (Rafael Wysocki)
- Add Lunar Lake-M PCI ID to the int340x Intel thermal driver
(Srinivas Pandruvada)
- Minor fixes for thermal governors (Rafael Wysocki, Di Shen)
- Trip point handling fixes for the iwlwifi wireless driver (Rafael
Wysocki)
- Code cleanups (Rafael J. Wysocki, AngeloGioacchino Del Regno)"

This release sees some exciting changes from David Lechner which
implements some optimisations that have been talked about for a long
time which allows client drivers to pre-prepare SPI messages for
repeated or low latency use. This lets us move work out of latency
sensitive paths and avoid repeating work for frequently performed
operations. As well as being useful in itself this will also be used in
future to allow controllers to directly trigger SPI operations (eg, from
interrupts).
Otherwise this release has mostly been focused on cleanups, plus a
couple of new devices:
- Support for pre-optimising messages.
- A big set of updates from Uwe Kleine-König moving drivers to use APIs
with more modern terminology for controllers.
- Major overhaul of the s3c64xx driver.
- Support for Google GS101 and Samsung Exynos850.

The current code only prints PKGC-10 residency when the PKGC-10
is not reached in previous 'freeze' attempt. To debug PKGC-10 issues, we
also need to know other PKGC residency counters to better triage issues.
Ex:
1. When system is stuck in PC2, it can be caused short LTR from device.
2. When system is stuck in PC8, it can be caused by display engine.
To better triage issues, all PKGC residency are needed when issues happen.
Example log:
CPU did not enter Package C10!!! (Package C10 cnt=0x0)
Prev Package C2 cnt = 0x2191a325de, Current Package C2 cnt = 0x21aba30724
Prev Package C3 cnt = 0x0, Current Package C3 cnt = 0x0
Prev Package C6 cnt = 0x0, Current Package C6 cnt = 0x0
Prev Package C7 cnt = 0x0, Current Package C7 cnt = 0x0
Prev Package C8 cnt = 0x0, Current Package C8 cnt = 0x0
Prev Package C9 cnt = 0x0, Current Package C9 cnt = 0x0
Prev Package C10 cnt = 0x0, Current Package C10 cnt = 0x0
With this log, we can know whether it's a stuck PC2 issue, and we can
check whether the short LTR from device causes the issue.
