2024-03-12dm raid: fix false positive for requeue needed during reshapeMing Lei
An empty flush doesn't have a payload, so it should never be looked at when considering to possibly requeue a bio for the case when a reshape is in progress.

2024-03-12drivers/gpio/nomadik: move dummy nmk_gpio_dbg_show_one() to headerMax Kellermann
When `CONFIG_DEBUG_FS` is disabled, nmk_gpio_dbg_show_one() is an empty dummy function; this however triggers a `-Wmissing-prototypes` warning and later a linker error because the function is also used by drivers/pinctrl/nomadik/pinctrl-nomadik.c, therefore it needs to be non-static. To allow both sources to access this dummy function, this patch moves it to the header, adding the `#ifdef CONFIG_DEBUG_FS` there as well.

2024-03-12platform/x86/intel/pmc: Improve PKGC residency counters debugKane Chen
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.

AAEON PICO-TGU4 board doesn't have any LED but there are bogus LED controls under /sys/class/leds: $ ls /sys/class/leds asus::kbd_backlight asus::lightbar platform::micmute The reason is that the ~0 read from asus_wmi_get_devstate() is treated as a valid state, in truth it means the device is absent.

2024-03-12x86/platform/atom: Check state of Punit managed devices on s2idleJohannes Stezenbach
For the Bay Trail or Cherry Trail SoC to enter the S0i3 power-level at s2idle suspend requires most of the hw-blocks / devices in the SoC to be in D3 when entering s2idle suspend. If some devices are not in D3 then the SoC will stay in a higher power state, consuming much more power from the battery then in S0i3. Use the new acpi_s2idle_dev_ops and acpi_register_lps0_dev() functionality to register a new s2idle check function which checks that all hardware blocks in the North complex (controlled by Punit) are in a state that allows the SoC to enter S0i3 and prints an error message for any device in D0.

2024-03-12platform/x86/intel/pmc/arl: Put GNA device in D3David E. Box
As is the case on Meteor Lake, the Gaussian & Neural Accelerator (GNA) device is powered by BIOS to D0 by default. If no driver is loaded, this will cause the Package C state to be limited to PC2, leading to significant power consumption and decrease in batter life. Put the GNA device in D3 by default if no driver is loaded for it. Fixes: 83f168a1a437 ("platform/x86/intel/pmc: Add Arrow Lake S support to intel_pmc_core driver") Signed-off-by: "David E.

2024-03-12platform/x86/intel/pmc/lnl: Remove SSRAM supportDavid E. Box
A recent PMC firmware change in Lunar Lake caused the pmc_core driver to fail to probe. This is due to a change in the GUID for PMC telemetry coming from the SSRAM device. Until a final release is ready this value may change again. In the meantime, disable the SSRAM support for Lunar Lake so the driver can load and provide some basic functionality.

2024-03-12platform/x86: wmi: Remove obsolete duplicate GUID allowlistArmin Wolf
The whitelist-based approach for preventing older WMI drivers from being instantiated multiple times has many drawbacks: - uses cannot see all available WMI devices (if not whitelisted) - whitelisting a WMI driver requires changes in the WMI driver core - maintenance burden for driver and subsystem developers Since the WMI driver core already takes care that older WMI drivers are not being instantiated multiple times, remove the now redundant whitelist. Tested on a ASUS Prime B650-Plus.

2024-03-12platform/x86: wmi: Do not instantiate older WMI drivers multiple timesArmin Wolf
Many older WMI drivers cannot be instantiated multiple times for two reasons: - they are using the legacy GUID-based WMI API - they are singletons (with global state) Prevent such WMI drivers from binding to WMI devices with a duplicated GUID, as this would mean that the WMI driver will be instantiated at least two times (one for the original GUID and one for the duplicated GUID). WMI drivers which can be instantiated multiple times can signal this by setting a flag inside struct wmi_driver. Tested on a ASUS Prime B650-Plus.

2024-03-12Merge branch 'linus' into x86/boot, to resolve conflictIngo Molnar
There's a new conflict with Linus's upstream tree, because in the following merge conflict resolution in <asm/coco.h>: 38b334fc767e Merge tag 'x86_sev_for_v6.9_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Linus has resolved the conflicting placement of 'cc_mask' better than the original commit: 1c811d403afd x86/sev: Fix position dependent variable references in startup code ... which was also done by an internal merge resolution: 2e5fc4786b7a Merge branch 'x86/sev' into x86/boot, to resolve conflicts and to pick up dependent tree But Linus is right in 38b334fc767e, the 'cc_mask' declaration is sufficient within the #ifdef CONFIG_ARCH_HAS_CC_PLATFORM block. So instead of forcing Linus to do the same resolution again, merge in Linus's tree and follow his conflict resolution.
