Cezanne platforms under the right circumstances have a synchronization problem where attempting to enter s2idle may fail if the x86 cores are put into HLT before hardware resume from the previous attempt has completed. To avoid this issue add a 10-20ms delay before entering s2idle another time. This workaround will only be applied on interrupts that wake the hardware but don't break the s2idle loop.

The event data of the WMI event 0xD0, which is assumed to be the fn_lock, is used to indicate several special keys on newer Yoga 7/9 laptops. The notify_id 0xD0 is non-unique in the DSDT of the Yoga 9 14IAP7, this causes wmi_get_event_data() to report wrong values. Port the ideapad-laptop WMI code to the wmi bus infrastructure which does not suffer from the shortcomings of wmi_get_event_data().

On some systems (like the Dell Inspiron 3505), the acpi operation region holding the ePPID string is two bytes too short, causing acpi functions like ToString() to omit the last two bytes. This does not happen on Windows, supposedly due to their implementation of ToString() ignoring buffer boundaries. Inform users if the ePPID length differs from the Dell specification so they can complain to Dell to fix their BIOS. Tested on a Dell Inspiron 3505.

When the DDV interface returns a buffer, it actually returns a acpi buffer containing an integer (buffer size) and another acpi buffer (buffer content). The size of the buffer may be smaller than the size of the buffer content, which is perfectly valid and should not be treated as an error. Also use the buffer size instead of the buffer content size when accessing the buffer to prevent accessing bogus data. Tested on a Dell Inspiron 3505.

Thinklight has only two values, on/off so it's reasonable for max_brightness to be 0 and 1 as if you write anything between 0 and 255 it will be 255 anyway so there's no point for it to be 255. This may look like it is a userspace API change, but writes with a value larget then the new max_brightness will still be accepted, these will be silently clamped to the new max_brightness by led_set_brightness_nosleep(). So no userspace API problems are expected.

The `huawei_wmi::idev` array is not actually used by the driver, so remove it. The piece of code that - I believe - was supposed to fill the array is flawed, it did not actually set any of the values inside the array. This was most likely masked by the fact that the input devices are devm managed and that the only function that needs a reference to the input devices is `huawei_wmi_input_notify()`, however, that does not access the appropriate input device via the `huawei_wmi` object.

Previously, `huawei_wmi_input_setup()` returned the result of logical or-ing the return values of two functions that return negative errno-style error codes and one that returns `acpi_status`. If this returned value was non-zero, then it was propagated from the platform driver's probe function. That function should return a negative errno-style error code, so the result of the logical or that `huawei_wmi_input_setup()` returned was not appropriate. Fix that by checking each function separately and returning the error code unmodified.

The dell-wmi-ddv driver adds support for reading the current temperature and ePPID of ACPI batteries on supported Dell machines. Since the WMI interface used by this driver does not do any input validation and thus cannot be used for probing, the driver depends on the ACPI battery extension machanism to discover batteries. The driver also supports a debugfs interface for retrieving buffers containing fan and thermal sensor information. Since the meaing of the content of those buffers is currently unknown, the interface is meant for reverse-engineering and will likely be replaced with an hwmon interface once the meaning has been understood. The driver was tested on a Dell Inspiron 3505.

Commit 3ae86d2d ("platform/x86: ideapad-laptop: Fix Legion 5 Fn lock LED") uses the WMI event-id for the fn-lock event on some Legion 5 laptops to manually toggle the fn-lock LED because the EC does not do it itself. However, the same WMI ID is also sent on some Yoga laptops. Here, setting the fn-lock state is not valid behavior, and causes the EC to spam interrupts until the laptop is rebooted. Add a set_fn_lock_led_list[] DMI-id list and only enable the workaround to manually set the LED on models on this list.

Add device nodes to enable support for battery and charger status, the ACPI platform profile, as well as internal and type-cover HID devices (including sensors, touchpad, keyboard, and other miscellaneous devices) on the Surface Pro 9. This does not include support for a tablet-mode switch yet, as that is now handled via the POS subsystem (unlike the Surface Pro 8, where it is handled via the KIP subsystem) and therefore needs further changes. While we're at it, also add the missing comment for the Surface Pro 8.

Currently, we check any received packet whether we have already seen it previously, regardless of the packet type (sequenced / unsequenced). We do this by checking the sequence number. This assumes that sequence numbers are valid for both sequenced and unsequenced packets. However, this assumption appears to be incorrect. On some devices, the sequence number field of unsequenced packets (in particular HID input events on the Surface Pro 9) is always zero. As a result, the current retransmission check kicks in and discards all but the first unsequenced packet, breaking (among other things) keyboard and touchpad input. Note that we have, so far, only seen packets being retransmitted in sequenced communication. In particular, this happens when there is an ACK timeout, causing the EC (or us) to re-send the packet waiting for an ACK. Arguably, retransmission / duplication of unsequenced packets should not be an issue as there is no logical condition (such as an ACK timeout) to determine when a packet should be sent again. Therefore, remove the retransmission check for unsequenced packets entirely to resolve the issue.

The current logic in the Intel PMC driver will forcefully attach it when detecting any CPU on the intel_pmc_core_platform_ids array, even if the matching ACPI device is not present. There's no checking in pmc_core_probe() to assert that the PMC device is present, and hence on virtualized environments the PMC device probes successfully, even if the underlying registers are not present. Before commit 21ae4357 ("platform/x86: intel_pmc_core: Substitute PCI with CPUID enumeration") the driver would check for the presence of a specific PCI device, and that prevented the driver from attaching when running virtualized. Fix by only forcefully attaching the PMC device when not running virtualized. Note that virtualized platforms can still get the device to load if the appropriate ACPI device is present on the tables provided to the VM. Make an exception for the Xen initial domain, which does have full hardware access, and hence can attach to the PMC if present.

We have accessing P2SB from a very few places for quite known hardware. When a new SoC appears in intel-family.h it's not obvious that it needs to be added to p2sb.c as well. Instead, provide default BDF and refactor p2sb_get_devfn() to always succeed. If in the future we would need to exclude something, we may add a list of unsupported IDs. Without this change the iTCO on Intel Comet Lake SoCs became unavailable: i801_smbus 0000:00:1f.4: failed to create iTCO device Fixes: 5c7b9167 ("i2c: i801: convert to use common P2SB accessor") Reported-and-tested-by: Jarkko Nikula <jarkko.nikula@linux.intel.com> Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Link: https://lore.kernel.org/r/20221104154916.35231-1-andriy.shevchenko@linux.intel.comReviewed-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Hans de Goede <hdegoede@redhat.com>

On Sapphire Rapids, due to a hardware issue affecting the PUNIT telemetry region, reads that are not done in QWORD quantities and alignment may return incorrect data. Use a custom 64-bit copy for this region. Signed-off-by: David E.
