2023-10-11cpu-hotplug: Provide prototypes for arch CPU registrationRussell King (Oracle)1-5/+0
Provide common prototypes for arch_register_cpu() and arch_unregister_cpu(). These are called by acpi_processor.c, with weak versions, so the prototype for this is already set. It is generally not necessary for function prototypes to be conditional on preprocessor macros. Some architectures (e.g. Loongarch) are missing the prototype for this, and rather than add it to Loongarch's asm/cpu.h, do the job once for everyone. Since this covers everyone, remove the now unnecessary prototypes in asm/cpu.h, and therefore remove the 'static' from one of ia64's arch_register_cpu() definitions.

Add void *context arrgument to the list of arguments of acpi_dev_install_notify_handler() and modify it to pass that argument as context to acpi_install_notify_handler() instead of its first argument which is problematic in general (for example, if platform drivers used it, they would rather get struct platform_device pointers or pointers to their private data from the context arguments of their notify handlers). Make all of the current callers of acpi_dev_install_notify_handler() take this change into account so as to avoid altering the general functionality.

2023-09-29ACPI: utils: Dynamically determine acpi_handle_list sizeRafael J. Wysocki1-3/+6
Address a long-standing "TBD" comment in the ACPI headers regarding the number of handles in struct acpi_handle_list. The number 10, which along with the comment dates back to 2.4.23, seems like it may have been arbitrarily chosen and isn't sufficient in all cases [1]. Finally change the code to dynamically determine the size of the handles table in struct acpi_handle_list and allocate it accordingly. Update the users of to struct acpi_handle_list to take the additional dynamic allocation into account.

2023-09-21ACPI: APEI: Fix AER info corruption when error status data has multiple sectionsShiju Jose1-0/+4
ghes_handle_aer() passes AER data to the PCI core for logging and recovery by calling aer_recover_queue() with a pointer to struct aer_capability_regs. The problem was that aer_recover_queue() queues the pointer directly without copying the aer_capability_regs data. The pointer was to the ghes->estatus buffer, which could be reused before aer_recover_work_func() reads the data. To avoid this problem, allocate a new aer_capability_regs structure from the ghes_estatus_pool, copy the AER data from the ghes->estatus buffer into it, pass a pointer to the new struct to aer_recover_queue(), and free it after aer_recover_work_func() has processed it.

2023-08-17ACPI: TAD: Install SystemCMOS address space handler for ACPI000EZhang Rui1-0/+9
Currently, the SystemCMOS address space handler is installed for the ACPI RTC devices (PNP0B00/PNP0B01/PNP0B02) only. But there are platforms with SystemCMOS Operetion Region defined under the ACPI Time and Alarm Device (ACPI000E), which is used by the ACPI pre-defined control methods like _GRT (Get the Real time) and _SRT (Set the Real time). When accessing these control methods via the acpi_tad sysfs interface, missing SystemCMOS address space handler causes errors like below [ 478.255453] ACPI Error: No handler for Region [RTCM] (00000000a8d2dd39) [SystemCMOS] (20230331/evregion-130) [ 478.255458] ACPI Error: Region SystemCMOS (ID=5) has no handler (20230331/exfldio-261) [ 478.255461] Initialized Local Variables for Method [_GRT]: [ 478.255461] Local1: 00000000f182542c <Obj> Integer 0000000000000000 [ 478.255464] No Arguments are initialized for method [_GRT] [ 478.255465] ACPI Error: Aborting method \_SB.AWAC._GRT due to previous error (AE_NOT_EXIST) (20230331/psparse-529) Export two APIs for SystemCMOS address space handler from acpi_cmos_rtc scan handler and install the handler for the ACPI Time and Alarm Device from the ACPI TAD driver.

2023-07-14ACPI: bus: Introduce wrappers for ACPICA notify handler install/removeMichal Wilczynski1-0/+6
Introduce new functions acpi_dev_install_notify_handler() and acpi_dev_remove_notify_handler(), to install and remove, respectively, a handler for AML Notify() operations targeted at a given ACPI device object. They will allow drivers to install Notify() handlers directly instead of providing an ACPI driver .notify() callback to be invoked in the context of a Notify() handler installed by the ACPI bus type code. In particular, this will help platform drivers to provide Notify() handlers for the ACPI companions of the platform devices they bind to. These functions are replacements for acpi_device_install_notify_handler() and acpi_device_remove_notify_handler(), respectively, and after all drivers switch over to using them, the old ones will be dropped.

2023-07-14ACPI: processor: Introduce acpi_processor_osc()Michal Wilczynski1-0/+1
The processor _OSC method is already used for a workaround introduced in commit a21211672c9a ("ACPI / processor: Request native thermal interrupt handling via _OSC"), but in accordance with ACPI 6.5 (and earlier), it should be used for negotiating all of the processor capabilities instead of _PDC (which has been deprecated since ACPI 3.0 and got removed from ACPI 6.5 entirely). Create a new callback function called acpi_processor_osc() to be invoked for every processor object and processor device in the ACPI namespace, in analogy with the already existing acpi_hwp_native_thermal_lvt_osc(). Make this function implement the workaround mentioned above and convey all of the OSPM processor support information to the platform firmware by setting all of the appropriate processor capabilities bits before evaluating _OSC for the given processor. For this purpose, make it call arch_acpi_set_proc_cap_bits() and modify the latter to set ACPI_PROC_CAP_COLLAB_PROC_PERF along with the other processor capabilities bits. Suggested-by: Rafael J.

2023-07-14ACPI: processor: Rename ACPI_PDC symbolsMichal Wilczynski2-36/+39
The prefix in the names of the ACPI_PDC symbols suggests that they are only relevant for _PDC, but in fact they can also be used in the _OSC. Change that prefix to a more generic ACPI_PROC_CAP that will better reflect the purpose of those symbols as they represent bits in a general processor capabilities buffer. Rename pdc_intel.h to proc_cap_intel.h to follow the change of the symbol name prefix. No intentional functional impact. Suggested-by: Rafael J.

ACPICA commit 8c048cee4ea7b9ded8db3e1b3b9c14e21e084a2c This adds 3 different external interrupt controller definitions in MADT for RISC-V. 1) RISC-V PLIC is a platform interrupt controller for handling wired interrupt in a RISC-V systems. 2) RISC-V IMSIC is MSI interrupt controller to support MSI interrupts. 3) RISC-V APLIC has dual functionality. First it can act like PLIC and direct all wired interrupts to the CPU which doesn't have MSI controller. Second, when the CPU has MSI controller (IMSIC), it will act as a converter from wired interrupts to MSI. Update the existing RINTC structure also to support these external interrupt controllers.

git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux Pull hardening updates from Kees Cook: "There are three areas of note: A bunch of strlcpy()->strscpy() conversions ended up living in my tree since they were either Acked by maintainers for me to carry, or got ignored for multiple weeks (and were trivial changes). The compiler option '-fstrict-flex-arrays=3' has been enabled globally, and has been in -next for the entire devel cycle. This changes compiler diagnostics (though mainly just -Warray-bounds which is disabled) and potential UBSAN_BOUNDS and FORTIFY _warning_ coverage. In other words, there are no new restrictions, just potentially new warnings. Any new FORTIFY warnings we've seen have been fixed (usually in their respective subsystem trees). For more details, see commit df8fc4e934c12b. The under-development compiler attribute __counted_by has been added so that we can start annotating flexible array members with their associated structure member that tracks the count of flexible array elements at run-time. It is possible (likely?) that the exact syntax of the attribute will change before it is finalized, but GCC and Clang are working together to sort it out. Any changes can be made to the macro while we continue to add annotations. As an example of that last case, I have a treewide commit waiting with such annotations found via Coccinelle: https://git.kernel.org/linus/adc5b3cb48a049563dc673f348eab7b6beba8a9b Also see commit dd06e72e68bcb4 for more details.

2023-06-15ACPI: sleep: Avoid breaking S3 wakeup due to might_sleep()Rafael J. Wysocki1-0/+1
The addition of might_sleep() to down_timeout() caused the latter to enable interrupts unconditionally in some cases, which in turn broke the ACPI S3 wakeup path in acpi_suspend_enter(), where down_timeout() is called by acpi_disable_all_gpes() via acpi_ut_acquire_mutex(). Namely, if CONFIG_DEBUG_ATOMIC_SLEEP is set, might_sleep() causes might_resched() to be used and if CONFIG_PREEMPT_VOLUNTARY is set, this triggers __cond_resched() which may call preempt_schedule_common(), so __schedule() gets invoked and it ends up with enabled interrupts (in the prev == next case). Now, enabling interrupts early in the S3 wakeup path causes the kernel to crash. Address this by modifying acpi_suspend_enter() to disable GPEs without attempting to acquire the sleeping lock which is not needed in that code path anyway.

2023-06-05ACPI: scan: Reduce overhead related to devices with dependenciesRafael J. Wysocki1-0/+2
Notice that all of the objects for which the acpi_scan_check_dep() return value is greater than 0 are present in acpi_dep_list as consumers (there may be multiple entries for one object, but that is not a problem), so after carrying out the initial ACPI namespace walk in which devices with dependencies are skipped, acpi_bus_scan() can simply walk acpi_dep_list and enumerate all of the unique consumer objects from there and their descendants instead of walking the entire target branch of the ACPI namespace and looking for device objects that have not been enumerated yet in it. Because walking acpi_dep_list is generally less overhead than walking the entire ACPI namespace, use the observation above to reduce the system initialization overhead related to ACPI, which is particularly important on large systems.

2023-04-11ACPI: video: Remove register_backlight_delay module option and codeHans de Goede1-2/+0
Since commit 5aa9d943e9b6 ("ACPI: video: Don't enable fallback path for creating ACPI backlight by default"), the delayed registering of acpi_video# backlight devices has been disabled by default. The few bugreports where this option was used as a workaround were all cases where the GPU driver did not call acpi_video_register_backlight() and the workaround was to pass video.register_backlight_delay=1. With the recent "ACPI: video: Make acpi_backlight=video work independent from GPU driver" changes acpi_backlight=video can be used to achieve the same result. So there is no need for the register_backlight_delay option + code anymore.

2023-04-06ACPICA: acpi_resource_irq: Replace 1-element arrays with flexible arrayKees Cook1-2/+8
ACPICA commit bfdd3446e7caf795c85c70326c137023942972c5 Similar to "Replace one-element array with flexible-array", replace the 1-element array with a proper flexible array member as defined by C99. This allows the code to operate without tripping compile-time and run- time bounds checkers (e.g. via __builtin_object_size(), -fsanitize=bounds, and/or -fstrict-flex-arrays=3). Note that the spec requires there be at least one interrupt, so use a union to keep space allocated for this. The only binary change in .text and .data sections is some rearrangement by the compiler of acpi_dm_address_common(), but appears to be harmless.

2023-04-06ACPICA: acpi_dmar_andd: Replace 1-element array with flexible arrayKees Cook1-1/+4
ACPICA commit 3c19ae70424e9ab1e1b805203d300d2660f9a2f7 Similar to "Replace one-element array with flexible-array", replace the 1-element array with a proper flexible array member as defined by C99. This allows the code to operate without tripping compile-time and run- time bounds checkers (e.g. via __builtin_object_size(), -fsanitize=bounds, and/or -fstrict-flex-arrays=3). The handling of struct acpi_dmar_andd by acpi_dm_dump_dmar() appears to expect a single trailing char for calculating table offsets. Keep a char in the union to avoid any code changes appearing in the .text or .data sections.
