2024-06-17ACPI: scan: Ignore camera graph port nodes on all Dell Tiger, Alder and ↵Hans de Goede2-9/+23
Raptor Lake models Dell laptops with IPU6 camera (the Tiger Lake, Alder Lake and Raptor Lake generations) have broken ACPI MIPI DISCO information (this results from an OEM attempt to make Linux work by supplying it with custom data in the ACPI tables which has never been supported in the mainline). Instead of adding a lot of DMI quirks for this, check for Dell platforms based on the processor generations in question and drop the ACPI graph port nodes, likely to be created with the help of invalid data, on all of them.

2024-06-17ACPICA: Revert "ACPICA: avoid Info: mapping multiple BARs. Your kernel is fine."Raju Rangoju1-21/+2
Undo the modifications made in commit d410ee5109a1 ("ACPICA: avoid "Info: mapping multiple BARs. Your kernel is fine.""). The initial purpose of this commit was to stop memory mappings for operation regions from overlapping page boundaries, as it can trigger warnings if different page attributes are present. However, it was found that when this situation arises, mapping continues until the boundary's end, but there is still an attempt to read/write the entire length of the map, leading to a NULL pointer deference. For example, if a four-byte mapping request is made but only one byte is mapped because it hits the current page boundary's end, a four-byte read/write attempt is still made, resulting in a NULL pointer deference. Instead, map the entire length, as the ACPI specification does not mandate that it must be within the same page boundary. It is permissible for it to be mapped across different regions.

2024-06-07ACPI: x86: Force StorageD3Enable on more productsMario Limonciello1-14/+10
A Rembrandt-based HP thin client is reported to have problems where the NVME disk isn't present after resume from s2idle. This is because the NVME disk wasn't put into D3 at suspend, and that happened because the StorageD3Enable _DSD was missing in the BIOS. As AMD's architecture requires that the NVME is in D3 for s2idle, adjust the criteria for force_storage_d3 to match *all* Zen SoCs when the FADT advertises low power idle support. This will ensure that any future products with this BIOS deficiency don't need to be added to the allow list of overrides.

2024-06-07thermal: ACPI: Invalidate trip points with temperature of 0 or belowRafael J. Wysocki1-1/+7
It is reported that commit 950210887670 ("thermal: core: Drop trips_disabled bitmask") causes the maximum frequency of CPUs to drop further down with every system sleep-wake cycle on Intel Core i7-4710HQ. This turns out to be due to a trip point whose temperature is equal to 0 degrees Celsius which is acted on every time the system wakes from sleep. Before commit 950210887670 this trip point would be disabled wia the trips_disabled bitmask, but now it is treated as a valid one. Since ACPI thermal control is generally about protection against overheating, trip points with temperature of 0 centigrade or below are not particularly useful there, so initialize them all as invalid which fixes the problem at hand.

2024-06-06irqchip/gic-v3: Enable non-coherent redistributors/ITSes ACPI probingLorenzo Pieralisi1-0/+15
The GIC architecture specification defines a set of registers for redistributors and ITSes that control the sharebility and cacheability attributes of redistributors/ITSes initiator ports on the interconnect (GICR_[V]PROPBASER, GICR_[V]PENDBASER, GITS_BASER<n>). Architecturally the GIC provides a means to drive shareability and cacheability attributes signals but it is not mandatory for designs to wire up the corresponding interconnect signals that control the cacheability/shareability of transactions. Redistributors and ITSes interconnect ports can be connected to non-coherent interconnects that are not able to manage the shareability/cacheability attributes; this implicitly makes the redistributors and ITSes non-coherent observers. To enable non-coherent GIC designs on ACPI based systems, parse the MADT GICC/GICR/ITS subtables non-coherent flags to determine whether the respective components are non-coherent observers and force the shareability attributes to be programmed into the redistributors and ITSes registers. An ACPI global function (acpi_get_madt_revision()) is added to retrieve the MADT revision, in that it is essential to check the MADT revision before checking for flags that were added with MADT revision 7 so that if the kernel is booted with an ACPI MADT table with revision < 7 it skips parsing the newly added flags (that should be zeroed reserved values for MADT versions < 7 but they could turn out to be buggy and should be ignored).

2024-05-16ACPI: EC: Install address space handler at the namespace rootRafael J. Wysocki2-10/+16
It is reported that _DSM evaluation fails in ucsi_acpi_dsm() on Lenovo IdeaPad Pro 5 due to a missing address space handler for the EC address space: ACPI Error: No handler for Region [ECSI] (000000007b8176ee) [EmbeddedControl] (20230628/evregion-130) This happens because if there is no ECDT, the EC driver only registers the EC address space handler for operation regions defined in the EC device scope of the ACPI namespace while the operation region being accessed by the _DSM in question is located beyond that scope. To address this, modify the ACPI EC driver to install the EC address space handler at the root of the ACPI namespace for the first EC that can be found regardless of whether or not an ECDT is present. Note that this change is consistent with some examples in the ACPI specification in which EC operation regions located outside the EC device scope are used (for example, see Section 9.17.15 in ACPI 6.5), so the current behavior of the EC driver is arguably questionable.

This allows user space to figure out which CXL region the event occured via trace event. - Connect CXL to CPER reporting. If a device is configured for firmware first, CXL event records are not sent directly to the host. Those records are reported through EFI Common Platform Error Records (CPER). Add support to route the CPER records through the CXL sub-system in order to provide DPA to HPA translation and also event decoding and tracing.

ACPI: - Support for the Firmware ACPI Control Structure (FACS) signature feature which is used to reboot out of hibernation on some systems Kbuild: - Support for building Flat Image Tree (FIT) images, where the kernel Image is compressed alongside a set of devicetree blobs Memory management: - Optimisation of our early page-table manipulation for creation of the linear mapping - Support for userfaultfd write protection, which brings along some nice cleanups to our handling of invalid but present ptes - Extend our use of range TLBI invalidation at EL1 Perf and PMUs: - Ensure that the 'pmu->parent' pointer is correctly initialised by PMU drivers - Avoid allocating 'cpumask_t' types on the stack in some PMU drivers - Fix parsing of the CPU PMU "version" field in assembly code, as it doesn't follow the usual architectural rules - Add best-effort unwinding support for USER_STACKTRACE - Minor driver fixes and cleanups Selftests: - Minor cleanups to the arm64 selftests (missing NULL check, unused variable) Miscellaneous: - Add a command-line alias for disabling 32-bit application support - Add part number for Neoverse-V2 CPUs - Minor fixes and cleanups" * tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: (64 commits) arm64/mm: Fix pud_user_accessible_page() for PGTABLE_LEVELS <= 2 arm64/mm: Add uffd write-protect support arm64/mm: Move PTE_PRESENT_INVALID to overlay PTE_NG arm64/mm: Remove PTE_PROT_NONE bit arm64/mm: generalize PMD_PRESENT_INVALID for all levels arm64: simplify arch_static_branch/_jump function arm64: Add USER_STACKTRACE support arm64: Add the arm64.no32bit_el0 command line option drivers/perf: hisi: hns3: Actually use devm_add_action_or_reset() drivers/perf: hisi: hns3: Fix out-of-bound access when valid event group drivers/perf: hisi_pcie: Fix out-of-bound access when valid event group kselftest: arm64: Add a null pointer check arm64: defer clearing DAIF.D arm64: assembler: update stale comment for disable_step_tsk arm64/sysreg: Update PIE permission encodings kselftest/arm64: Remove unused parameters in abi test perf/arm-spe: Assign parents for event_source device perf/arm-smmuv3: Assign parents for event_source device perf/arm-dsu: Assign parents for event_source device perf/arm-dmc620: Assign parents for event_source device ...
