Also significant is the switch-over to threaded interrupt handlers for the ACPI SCI and the dedicated EC interrupt (on systems where the former is not used) which essentially allows all ACPI code to run with local interrupts enabled. That should improve responsiveness significantly on systems where multiple GPEs are enabled and the handling of one SCI involves many I/O address space accesses which previously had to be carried out in one go with disabled interrupts on the local CPU. Apart from the above, the ACPI thermal zone driver will use the Thermal fast Sampling Period (_TFP) object if available, which should allow temperature changes to be followed more accurately on some systems, the ACPI Notify () handlers can run on all CPUs (not just on CPU0), which should generally speed up the processing of events signaled through the ACPI SCI, and the ACPI power button driver will trigger wakeup key events via the input subsystem (on systems where it is a system wakeup device) In addition to that, there are the usual bunch of fixes and cleanups. Specifics: - Add CSI-2 and DisCo for Imaging support to the ACPI device enumeration code (Sakari Ailus, Rafael J. Wysocki) - Adjust the cpufreq thermal reduction algorithm in the ACPI processor driver for Tegra241 (Srikar Srimath Tirumala, Arnd Bergmann) - Make acpi_proc_quirk_mwait_check() x86-specific (Rafael J. Wysocki) - Switch over ACPI to using a threaded interrupt handler for the SCI (Rafael J. Wysocki) - Allow ACPI Notify () handlers to run on all CPUs and clean up the ACPI interface for deferred events processing (Rafael J. Wysocki) - Switch over the ACPI EC driver to using a threaded handler for the dedicated IRQ on systems without the EC GPE (Rafael J. Wysocki) - Adjust code using ACPICA spinlocks and the ACPI EC driver spinlock to keep local interrupts on (Rafael J. Wysocki) - Adjust the USB4 _OSC handshake to correctly handle cases in which certain types of OS control are denied by the platform (Mika Westerberg) - Correct and clean up the generic function for parsing ACPI data-only tables with array structure (Yuntao Wang) - Modify acpi_dev_uid_match() to support different types of its second argument and adjust its users accordingly (Raag Jadav) - Clean up code related to acpi_evaluate_reference() and ACPI device lists (Rafael J. Wysocki) - Use generic ACPI helpers for evaluating trip point temperature objects in the ACPI thermal zone driver (Rafael J. Wysockii, Arnd Bergmann) - Add Thermal fast Sampling Period (_TFP) support to the ACPI thermal zone driver (Jeff Brasen) - Modify the ACPI LPIT table handling code to avoid u32 multiplication overflows in state residency computations (Nikita Kiryushin) - Drop an unused helper function from the ACPI backlight (video) driver and add a clarifying comment to it (Hans de Goede) - Update the ACPI backlight driver to avoid using uninitialized memory in some cases (Nikita Kiryushin) - Add ACPI backlight quirk for the Colorful X15 AT 23 laptop (Yuluo Qiu) - Add support for vendor-defined error types to the ACPI APEI error injection code (Avadhut Naik) - Adjust APEI to properly set MF_ACTION_REQUIRED on synchronous memory failure events, so they are handled differently from the asynchronous ones (Shuai Xue) - Fix NULL pointer dereference check in the ACPI extlog driver (Prarit Bhargava) - Adjust the ACPI extlog driver to clear the Extended Error Log status when RAS_CEC handled the error (Tony Luck) - Add IRQ override quirks for some Infinity laptops and for TongFang GMxXGxx (David McFarland, Hans de Goede) - Clean up the ACPI NUMA code and fix it to ensure that fake_pxm is not the same as one of the real pxm values (Yuntao Wang) - Fix the fractional clock divider flags in the ACPI LPSS (Intel SoC) driver so as to prevent miscalculation of the values in the clock divider (Andy Shevchenko) - Adjust comments in the ACPI watchdog driver to prevent kernel-doc from complaining during documentation builds (Randy Dunlap) - Make the ACPI button driver send wakeup key events to user space in addition to power button events on systems that can be woken up by the power button (Ken Xue) - Adjust pnpacpi_parse_allocated_vendor() to use memcpy() on a full structure field (Dmitry Antipov)" * tag 'acpi-6.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (56 commits) ACPI: resource: Add Infinity laptops to irq1_edge_low_force_override ACPI: button: trigger wakeup key events ACPI: resource: Add another DMI match for the TongFang GMxXGxx ACPI: EC: Use a spin lock without disabing interrupts ACPI: EC: Use a threaded handler for dedicated IRQ ACPI: OSL: Use spin locks without disabling interrupts ACPI: APEI: set memory failure flags as MF_ACTION_REQUIRED on synchronous events ACPI: utils: Introduce helper for _DEP list lookup ACPI: utils: Fix white space in struct acpi_handle_list definition ACPI: utils: Refine acpi_handle_list_equal() slightly ACPI: utils: Return bool from acpi_evaluate_reference() ACPI: utils: Rearrange in acpi_evaluate_reference() ACPI: arm64: export acpi_arch_thermal_cpufreq_pctg() ACPI: extlog: Clear Extended Error Log status when RAS_CEC handled the error ACPI: LPSS: Fix the fractional clock divider flags ACPI: NUMA: Fix the logic of getting the fake_pxm value ACPI: NUMA: Optimize the check for the availability of node values ACPI: NUMA: Remove unnecessary check in acpi_parse_gi_affinity() ACPI: watchdog: fix kernel-doc warnings ACPI: extlog: fix NULL pointer dereference check ...

* PNP: replace deprecated strncpy() with memcpy()Justin Stitt2023-10-201-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | strncpy() is deprecated for use on NUL-terminated destination strings [1] and as such we should prefer more robust and less ambiguous interfaces. After having precisely calculated the lengths and ensuring we don't overflow the buffer, this really decays to just a memcpy. Let's not use a C string api as it makes the intention of the code confusing. It'd be nice to use strscpy() in this case (as we clearly want NUL-termination) because it'd clean up the code a bit. However, I don't quite know enough about what is going on here to justify a drop-in replacement -- too much bit magic and why (PNP_NAME_LEN - 2)? I'm afraid using strscpy() may result in copying too many or too few bytes into our dev->name buffer resulting in different behavior. At least using memcpy() we can ensure the behavior is exactly the same. Side note: NUL-padding is not required because insert_device() calls pnpbios_parse_data_stream() with a zero-allocated `dev`: 299 | static int __init insert_device(struct pnp_bios_node *node) { ... 312 | dev = pnp_alloc_dev(&pnpbios_protocol, node->handle, id); ... 316 | pnpbios_parse_data_stream(dev, node); then pnpbios_parse_data_stream() calls pnpbios_parse_compatible_ids().

* PNP: ACPI: replace deprecated strncpy() with strscpy()Justin Stitt2023-10-201-5/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | strncpy() is deprecated for use on NUL-terminated destination strings [1] and as such we should prefer more robust and less ambiguous string interfaces. We know dev->name should be NUL-terminated based on the presence of a manual NUL-byte assignment. NUL-padding is not required as dev is already zero-allocated which renders any further NUL-byte assignments redundant: dev = pnp_alloc_dev(&pnpacpi_protocol, num, pnpid); ---> dev = kzalloc(sizeof(struct pnp_dev), GFP_KERNEL); Considering the above, a suitable replacement is `strscpy` [2] due to the fact that it guarantees NUL-termination on the destination buffer without unnecessarily NUL-padding. This simplifies the code and makes the intent/behavior more obvious.

* PNP: Do not disable devices on suspend when they cannot be re-enabled on resumeHans de Goede2022-11-251-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | On an Advantech MICA-071 tablet, with a builtin barcode scanner connected to ttyS0, the following message is shown on suspend: serial 00:02: disabled And after suspend/resume trying to use the barcode scanner / ttyS0 shows: serial 00:02: LSR safety check engaged! Indicating that the UARTs io-ports are no longer reachable. This is caused by __pnp_bus_suspend() calling pnp_stop_dev() on the "00:02" pnp device on suspend (this outputs the disabled message). The problem is that pnp_can_write() returns false for the "00:02" pnp device, so after disabling it (disabling its decoding of IO addresses) during suspend, it cannot be re-enabled. Add a pnp_can_write() check to the suspend path and only disable devices which can actually be re-enabled on resume. This fixes the Advantech MICA-071's ttyS0 no longer working after a suspend/resume. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

* bus: Make remove callback return voidUwe Kleine-König2021-07-211-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The driver core ignores the return value of this callback because there is only little it can do when a device disappears. This is the final bit of a long lasting cleanup quest where several buses were converted to also return void from their remove callback. Additionally some resource leaks were fixed that were caused by drivers returning an error code in the expectation that the driver won't go away. With struct bus_type::remove returning void it's prevented that newly implemented buses return an ignored error code and so don't anticipate wrong expectations for driver authors.

* PNPBIOS: Replace zero-length array with flexible-arrayGustavo A. R. Silva2020-05-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] sizeof(flexible-array-member) triggers a warning because flexible array members have incomplete type[1]. There are some instances of code in which the sizeof operator is being incorrectly/erroneously applied to zero-length arrays and the result is zero. Such instances may be hiding some bugs. So, this work (flexible-array member conversions) will also help to get completely rid of those sorts of issues. This issue was found with the help of Coccinelle.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | %pF and %pf are functionally equivalent to %pS and %ps conversion specifiers. The former are deprecated, therefore switch the current users to use the preferred variant. The changes have been produced by the following command: git grep -l '%p[fF]' | grep -v '^\(tools\|Documentation\)/' | \ while read i; do perl -i -pe 's/%pf/%ps/g; s/%pF/%pS/g;' $i; done And verifying the result.
