platform/x86: p2sb: Don't fail if unknown CPU is found

2022-11-07T11:33:49Z

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: 5c7b9167ddf8 ("i2c: i801: convert to use common P2SB accessor") Reported-and-tested-by: Jarkko Nikula Signed-off-by: Andy Shevchenko Link: https://lore.kernel.org/r/20221104154916.35231-1-andriy.shevchenko@linux.intel.com Reviewed-by: Hans de Goede Signed-off-by: Hans de Goede

platform/x86/intel/pmt: Sapphire Rapids PMT errata fix

2022-11-07T11:33:49Z

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.

platform/x86: hp_wmi: Fix rfkill causing soft blocked wifi

2022-11-07T11:33:49Z

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.

platform/x86/amd: pmc: Read SMU version during suspend on Cezanne systems

2022-10-24T09:27:35Z

commit b0c07116c894 ("platform/x86: amd-pmc: Avoid reading SMU version at probe time") adjusted the behavior for amd-pmc to avoid reading the SMU version at startup but rather on first use to improve boot time. However the SMU version is also used to decide whether to place a timer based wakeup in the OS_HINT message. If the idlemask hasn't been read before this message was sent then the SMU version will not have been cached. Ensure the SMU version has been read before deciding whether or not to run this codepath.

thinkpad_acpi was reporting 2 fans on a ThinkPad T14s gen 1, even though the laptop has only 1 fan. The second, not present fan always reads 65535 (-1 in 16 bit signed), ignore fans which report 65535 to avoid reporting the non present fan.
