Add debugfs interface for debugging TPMI configuration and register contents. This shows PFS (PM Feature structure) for each TPMI device. For each feature, show full register contents and allow to modify register at an offset. This debugfs interface is not present on locked down kernel with no DEVMEM access and without CAP_SYS_RAWIO permission. Signed-off-by:

Some of the PM features can be locked or disabled. In that case, write interface can be locked. This status is read via a mailbox. There is one TPMI ID which provides base address for interface and data register for mail box operation. The mailbox operations is defined in the TPMI specification. Refer to https://github.com/intel/tpmi_power_management/ for TPMI specifications. An API is exposed to feature drivers to read feature control status. Signed-off-by:

Immutable branch between pdx86 simatic branch and LED due for the v6.6 merge window v6.5-rc1 + recent pdx86 simatic-ipc patches for merging into the LED subsystem for v6.6.

We recently introduced a way to name additional modules to load for each device. Use that instead of wdtmode to load the watchdog module. This patch does not change behaviour, it is just style. Signed-off-by:

In order to know which hwmon modules to load one would have to usually first probe from user-land i.e. with sensors-detect and create a config for each machine. But here we know exactly what machines we are dealing with, so we can request those howmon modules without user-mode detection and config files. Signed-off-by:

Siemens Simatic Industrial PCs can monitor the voltage of the CMOS battery with two bits that indicate low or empty state. This can be GPIO or PortIO based. Here we model that as a hwmon voltage. The core driver does the PortIO and provides boilerplate for the GPIO versions. Which are split out to model runtime dependencies while allowing fine-grained kernel configuration. Signed-off-by:

The IO region used for the watchdog also hold CMOS battery monitoring information. Make the access muxed so that a hwmon driver can use the region as well. Signed-off-by:

Instead of relying on free-form comments to document locking requirements use well-known lockdep annotations. These can also be validated at runtime make sure the invariants are not violated. Signed-off-by:

hotkey_mask_set() and hotkey_mask_get() expect hotkey_mutex to be held. While it should not matter during initialization a following patch will enable lockdep for hotkey_mutex which would produce warnings here. Signed-off-by:

Expose various CPU and dGPU tunables that are available on many ASUS ROG laptops. The tunables shown in sysfs will vary depending on the CPU and dGPU vendor. All of these variables are write only and there is no easy way to find what the defaults are. In general they seem to default to the max value the vendor sets for the CPU and dGPU package - this is not the same as the min/max writable value. Values written to these variables that are beyond the capabilities of the CPU are ignored by the laptop. Signed-off-by:

Add safety checking to dgpu_disable, egpu_enable, gpu_mux_mode. These checks prevent users from doing such things as: - disabling the dGPU while is muxed to drive the internal screen - enabling the eGPU which also disables the dGPU, while muxed to the internal screen - switching the MUX to dGPU while the dGPU is disabled Signed-off-by:

We just sorted the entries and fields last release, so just out of a perverse sense of curiosity, I decided to see if we can keep things ordered for even just one release. The answer is "No. No we cannot". I suggest that all kernel developers will need weekly training sessions, involving a lot of Big Bird and Sesame Street. And at the yearly maintainer summit, we will all sing the alphabet song together. I doubt I will keep doing this. At some point "perverse sense of curiosity" turns into just a cold dark place filled with sadness and despair. Repeats: 80e62bc8 ("MAINTAINERS: re-sort all entries and fields") Signed-off-by:

Pull x86 fix from Thomas Gleixner: "A single fix for the mechanism to park CPUs with an INIT IPI. On shutdown or kexec, the kernel tries to park the non-boot CPUs with an INIT IPI. But the same code path is also used by the crash utility. If the CPU which panics is not the boot CPU then it sends an INIT IPI to the boot CPU which resets the machine. Prevent this by validating that the CPU which runs the stop mechanism is the boot CPU. If not, leave the other CPUs in HLT" * tag 'x86-core-2023-07-09' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/smp: Don't send INIT to boot CPU
