2024-12-19ACPI: bus: change the prototype for acpi_get_physical_device_locationRicardo Ribalda3-9/+5
It generally is not OK to use acpi_status and/or AE_ error codes without CONFIG_ACPI and they really only should be used in drivers/acpi/ (and not everywhere in there for that matter). So acpi_get_physical_device_location() needs to be redefined to return something different from acpi_status (preferably bool) in order to be used in !CONFIG_ACPI code. Suggested-by: Rafael J.

2024-12-18ACPI: EC: Enable EC support on LoongArch by defaultHuacai Chen1-2/+2
Commit a6021aa24f6417416d933 ("ACPI: EC: make EC support compile-time conditional") only enable ACPI_EC on X86 by default, but the embedded controller is also widely used on LoongArch laptops so we also enable ACPI_EC for LoongArch. The laptop driver cannot work without EC, so also update the dependency of LOONGSON_LAPTOP to let it depend on APCI_EC.

2024-12-10ACPI: OSL: Use usleep_range() in acpi_os_sleep()Rafael J. Wysocki1-1/+21
As stated by Len in [1], the extra delay added by msleep() to the sleep time value passed to it can be significant, roughly between 1.5 ns on systems with HZ = 1000 and as much as 15 ms on systems with HZ = 100, which is hardly acceptable, at least for small sleep time values. msleep(5) on the default HZ = 250 in Ubuntu on a modern PC takes about 12 ms. This results in over 800 ms of spurious system resume delay on systems such as the Dell XPS-13-9300, which use ASL Sleep(5ms) in a tight loop. Address this by using usleep_range() in acpi_os_sleep() instead of msleep(). For short sleep times this is a no brainer, but even for long sleeps usleep_range() should be preferred because timer wheel timers are optimized for cancelation before they expire and this particular timer is not going to be canceled. Add at least 50 us on top of the requested sleep time in case the timer can be subject to coalescing, which is consistent with what's done in user space in this context [2], but for sleeps longer than 5 ms use 1% of the requested sleep time for this purpose. The rationale here is that longer sleeps don't need that much of a timer precision as a rule and making the timer a more likely candidate for coalescing in these cases is generally desirable. It starts at 5 ms so that the delta between the requested sleep time and the effective deadline is a contiuous function of the former.

2024-12-10ACPI: platform_profile: Allow multiple handlersMario Limonciello1-11/+0
Multiple drivers may attempt to register platform profile handlers, but only one may be registered and the behavior is non-deterministic for which one wins. It's mostly controlled by probing order. This can be problematic if one driver changes CPU settings and another driver notifies the EC for changing fan curves. Modify the ACPI platform profile handler to let multiple drivers register platform profile handlers and abstract this detail from userspace. To avoid undefined behaviors only offer profiles that are commonly advertised across multiple handlers. If any problems occur when changing profiles for any driver, then the drivers that were already changed remain changed and the legacy sysfs handler will report 'custom'.

2024-12-04acpi: nfit: vmalloc-out-of-bounds Read in acpi_nfit_ctlSuraj Sonawane1-1/+6
Fix an issue detected by syzbot with KASAN: BUG: KASAN: vmalloc-out-of-bounds in cmd_to_func drivers/acpi/nfit/ core.c:416 [inline] BUG: KASAN: vmalloc-out-of-bounds in acpi_nfit_ctl+0x20e8/0x24a0 drivers/acpi/nfit/core.c:459 The issue occurs in cmd_to_func when the call_pkg->nd_reserved2 array is accessed without verifying that call_pkg points to a buffer that is appropriately sized as a struct nd_cmd_pkg. This can lead to out-of-bounds access and undefined behavior if the buffer does not have sufficient space. To address this, a check was added in acpi_nfit_ctl() to ensure that buf is not NULL and that buf_len is less than sizeof(*call_pkg) before accessing it. This ensures safe access to the members of call_pkg, including the nd_reserved2 array.

2024-11-22ACPI: introduce acpi_arch_init()Miao Wang3-4/+5
To avoid arch-specific code in general ACPI initialization flow, introduce a weak symbol acpi_arch_init(). Currently, arm64 and riscv can utillize this to insert their arch-specific flow. In the future, other architectures can also have a chance to define their own arch-specific ACPI initialization process if necessary.

The Acer Iconia One 8 A1-840 (not to be confused with the A1-840FHD which is a different model) ships with Android 4.4 as factory OS and has the usual broken DSDT issues for x86 Android tablets.

git://git.kernel.org/pub/scm/linux/kernel/git/jgg/iommufd Pull iommufd updates from Jason Gunthorpe: "Several new features and uAPI for iommufd: - IOMMU_IOAS_MAP_FILE allows passing in a file descriptor as the backing memory for an iommu mapping. To date VFIO/iommufd have used VMA's and pin_user_pages(), this now allows using memfds and memfd_pin_folios(). Notably this creates a pure folio path from the memfd to the iommu page table where memory is never broken down to PAGE_SIZE. - IOMMU_IOAS_CHANGE_PROCESS moves the pinned page accounting between two processes. Combined with the above this allows iommufd to support a VMM re-start using exec() where something like qemu would exec() a new version of itself and fd pass the memfds/iommufd/etc to the new process. The memfd allows DMA access to the memory to continue while the new process is getting setup, and the CHANGE_PROCESS updates all the accounting. - Support for fault reporting to userspace on non-PRI HW, such as ARM stall-mode embedded devices. - IOMMU_VIOMMU_ALLOC introduces the concept of a HW/driver backed virtual iommu. This will be used by VMMs to access hardware features that are contained with in a VM. The first use is to inform the kernel of the virtual SID to physical SID mapping when issuing SID based invalidation on ARM. Further uses will tie HW features that are directly accessed by the VM, such as invalidation queue assignment and others. - IOMMU_VDEVICE_ALLOC informs the kernel about the mapping of virtual device to physical device within a VIOMMU. Minimially this is used to translate VM issued cache invalidation commands from virtual to physical device IDs. - Enhancements to IOMMU_HWPT_INVALIDATE and IOMMU_HWPT_ALLOC to work with the VIOMMU - ARM SMMuv3 support for nested translation. Using the VIOMMU and VDEVICE the driver can model this HW's behavior for nested translation.
