2022-11-16platform/x86: ideapad-laptop: Fix interrupt storm on fn-lock toggle on some ↵Arnav Rawat
Yoga laptops Commit 3ae86d2d4704 ("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.

2022-11-15platform/surface: aggregator: Do not check for repeated unsequenced packetsMaximilian Luz
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.

2022-11-15platform/x86/intel: pmc: Don't unconditionally attach Intel PMC when virtualizedRoger Pau Monné
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 21ae43570940 ("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.

2022-11-07platform/x86: hp_wmi: Fix rfkill causing soft blocked wifiJorge Lopez
After upgrading BIOS to U82 01.02.01 Rev.A, the console is flooded strange char "^@" which printed out every second and makes login nearly impossible. Also the below messages were shown both in console and journal/dmesg every second: usb 1-3: Device not responding to setup address. usb 1-3: device not accepting address 4, error -71 usb 1-3: device descriptor read/all, error -71 usb usb1-port3: unable to enumerate USB device Wifi is soft blocked by checking rfkill. When unblocked manually, after few seconds it would be soft blocked again. So I was suspecting something triggered rfkill to soft block wifi. At the end it was fixed by removing hp_wmi module. The root cause is the way hp-wmi driver handles command 1B on post-2009 BIOS. In pre-2009 BIOS, command 1Bh return 0x4 to indicate that BIOS no longer controls the power for the wireless devices.

If the system has entered s2idle once, but was woken up never breaking the s2idle loop but also never went back to sleep we might still have another issue to deal with however.

2022-09-27platform/x86/amd/pmf: install notify handler after acpi initShyam Sundar S K
It is observed that when thinkpad_acpi driver loads before amd-pmf driver, thinkpad_acpi driver sends the AMT "on" event and the request immediately will be part of the PMF BIOS "pending requests". With the current amd-pmf code, as soon as the amd-pmf driver gets probed, it calls apmf_acpi_init() where the notify handler will be installed. Handler callback would call amd_pmf_handle_amt() where the amd_pmf_set_automode() shall update the auto-mode thermals. In this case, the auto-mode config_store shall have "zeros", as the auto mode init gets called during the later stage. To fix this, change the order of the acpi notifer install and call it after the auto mode initialization is done.
