ACPI: x86: Drop quirk for HP Elitebook
There was a quirk in `acpi/x86/s2idle.c` for an HP Elitebook G9 platforms to force AMD GUID codepath instead of Microsoft codepath. This was due to a bug with WCN6855 WLAN firmware interaction with the system. This bug is fixed by WCN6855 firmware: WLAN.HSP.1.1-03125-QCAHSPSWPL_V1_V2_SILICONZ_LITE-3.6510.23 Remove the quirk as it's no longer necessary with this firmware.

cxl for v6.3
- CXL RAM region enumeration: instantiate 'struct cxl_region' objects for platform firmware created memory regions - CXL RAM region provisioning: complement the existing PMEM region creation support with RAM region support - "Soft Reservation" policy change: Online (memory hot-add) soft-reserved memory (EFI_MEMORY_SP) by default, but still allow for setting aside such memory for dedicated access via device-dax. - CXL Events and Interrupts: Takeover CXL event handling from platform-firmware (ACPI calls this CXL Memory Error Reporting) and export CXL Events via Linux Trace Events. - Convey CXL _OSC results to drivers: Similar to PCI, let the CXL subsystem interrogate the result of CXL _OSC negotiation. - Emulate CXL DVSEC Range Registers as "decoders": Allow for first-generation devices that pre-date the definition of the CXL HDM Decoder Capability to translate the CXL DVSEC Range Registers into 'struct cxl_decoder' objects. - Set timestamp: Per spec, set the device timestamp in case of hotplug, or if platform-firwmare failed to set it. - General fixups: linux-next build issues, non-urgent fixes for pre-production hardware, unit test fixes, spelling and debug message improvements. -----BEGIN PGP SIGNATURE----- iHUEABYKAB0WIQSbo+XnGs+rwLz9XGXfioYZHlFsZwUCY/WYcgAKCRDfioYZHlFs Z6m3APkBUtiEEm1o8ikdu5llUS1OTLBwqjJDwGMTyf8X/WDXhgD+J2mLsCgARS7X 5IS0RAtefutrW5sQpUucPM7QiLuraAY= =kOXC -----END PGP SIGNATURE----- Merge tag 'cxl-for-6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl Pull Compute Express Link (CXL) updates from Dan Williams: "To date Linux has been dependent on platform-firmware to map CXL RAM regions and handle events / errors from devices. With this update we can now parse / update the CXL memory layout, and report events / errors from devices. This is a precursor for the CXL subsystem to handle the end-to-end "RAS" flow for CXL memory. i.e. the flow that for DDR-attached-DRAM is handled by the EDAC driver where it maps system physical address events to a field-replaceable-unit (FRU / endpoint device). In general, CXL has the potential to standardize what has historically been a pile of memory-controller-specific error handling logic. Another change of note is the default policy for handling RAM-backed device-dax instances. Previously the default access mode was "device", mmap(2) a device special file to access memory. The new default is "kmem" where the address range is assigned to the core-mm via add_memory_driver_managed(). This saves typical users from wondering why their platform memory is not visible via free(1) and stuck behind a device-file. At the same time it allows expert users to deploy policy to, for example, get dedicated access to high performance memory, or hide low performance memory from general purpose kernel allocations. This affects not only CXL, but also systems with high-bandwidth-memory that platform-firmware tags with the EFI_MEMORY_SP (special purpose) designation. Summary: - CXL RAM region enumeration: instantiate 'struct cxl_region' objects for platform firmware created memory regions - CXL RAM region provisioning: complement the existing PMEM region creation support with RAM region support - "Soft Reservation" policy change: Online (memory hot-add) soft-reserved memory (EFI_MEMORY_SP) by default, but still allow for setting aside such memory for dedicated access via device-dax. - CXL Events and Interrupts: Takeover CXL event handling from platform-firmware (ACPI calls this CXL Memory Error Reporting) and export CXL Events via Linux Trace Events. - Convey CXL _OSC results to drivers: Similar to PCI, let the CXL subsystem interrogate the result of CXL _OSC negotiation. - Emulate CXL DVSEC Range Registers as "decoders": Allow for first-generation devices that pre-date the definition of the CXL HDM Decoder Capability to translate the CXL DVSEC Range Registers into 'struct cxl_decoder' objects. - Set timestamp: Per spec, set the device timestamp in case of hotplug, or if platform-firwmare failed to set it. - General fixups: linux-next build issues, non-urgent fixes for pre-production hardware, unit test fixes, spelling and debug message improvements" * tag 'cxl-for-6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl: (66 commits) dax/kmem: Fix leak of memory-hotplug resources cxl/mem: Add kdoc param for event log driver state cxl/trace: Add serial number to trace points cxl/trace: Add host output to trace points cxl/trace: Standardize device information output cxl/pci: Remove locked check for dvsec_range_allowed() cxl/hdm: Add emulation when HDM decoders are not committed cxl/hdm: Create emulated cxl_hdm for devices that do not have HDM decoders cxl/hdm: Emulate HDM decoder from DVSEC range registers cxl/pci: Refactor cxl_hdm_decode_init() cxl/port: Export cxl_dvsec_rr_decode() to cxl_port cxl/pci: Break out range register decoding from cxl_hdm_decode_init() cxl: add RAS status unmasking for CXL cxl: remove unnecessary calling of pci_enable_pcie_error_reporting() dax/hmem: build hmem device support as module if possible dax: cxl: add CXL_REGION dependency cxl: avoid returning uninitialized error code cxl/pmem: Fix nvdimm registration races cxl/mem: Fix UAPI command comment cxl/uapi: Tag commands from cxl_query_cmd() ... |

Driver core changes for 6.3-rc1
Here is the large set of driver core changes for 6.3-rc1. There's a lot of changes this development cycle, most of the work falls into two different categories: - fw_devlink fixes and updates. This has gone through numerous review cycles and lots of review and testing by lots of different devices. Hopefully all should be good now, and Saravana will be keeping a watch for any potential regression on odd embedded systems. - driver core changes to work to make struct bus_type able to be moved into read-only memory (i.e. const) The recent work with Rust has pointed out a number of areas in the driver core where we are passing around and working with structures that really do not have to be dynamic at all, and they should be able to be read-only making things safer overall. This is the contuation of that work (started last release with kobject changes) in moving struct bus_type to be constant. We didn't quite make it for this release, but the remaining patches will be finished up for the release after this one, but the groundwork has been laid for this effort. Other than that we have in here: - debugfs memory leak fixes in some subsystems - error path cleanups and fixes for some never-able-to-be-hit codepaths. - cacheinfo rework and fixes - Other tiny fixes, full details are in the shortlog All of these have been in linux-next for a while with no reported problems.

ACPI: resource: Skip IRQ override on Asus Expertbook B2402FBA
The Asus Expertbook B2502FBA has IRQ 1 described as Active_Low in its ACPI table. However, the kernel overrides this and sets it to Edge_High, which prevents the internal keyboard from working properly. Adding this laptop model to the override_table fixes the issue.

arm64 updates for 6.3:
- Support for arm64 SME 2 and 2.1. SME2 introduces a new 512-bit architectural register (ZT0, for the look-up table feature) that Linux needs to save/restore. - Include TPIDR2 in the signal context and add the corresponding kselftests. - Perf updates: Arm SPEv1.2 support, HiSilicon uncore PMU updates, ACPI support to the Marvell DDR and TAD PMU drivers, reset DTM_PMU_CONFIG (ARM CMN) at probe time. - Support for DYNAMIC_FTRACE_WITH_CALL_OPS on arm64. - Permit EFI boot with MMU and caches on. Instead of cleaning the entire loaded kernel image to the PoC and disabling the MMU and caches before branching to the kernel bare metal entry point, leave the MMU and caches enabled and rely on EFI's cacheable 1:1 mapping of all of system RAM to populate the initial page tables. - Expose the AArch32 (compat) ELF_HWCAP features to user in an arm64 kernel (the arm32 kernel only defines the values). - Harden the arm64 shadow call stack pointer handling: stash the shadow stack pointer in the task struct on interrupt, load it directly from this structure. - Signal handling cleanups to remove redundant validation of size information and avoid reading the same data from userspace twice. - Refactor the hwcap macros to make use of the automatically generated ID registers. It should make new hwcaps writing less error prone. - Further arm64 sysreg conversion and some fixes. - arm64 kselftest fixes and improvements. - Pointer authentication cleanups: don't sign leaf functions, unify asm-arch manipulation. - Pseudo-NMI code generation optimisations. - Minor fixes for SME and TPIDR2 handling. - Miscellaneous updates: ARCH_FORCE_MAX_ORDER is now selectable, replace strtobool() to kstrtobool() in the cpufeature.c code, apply dynamic shadow call stack in two passes, intercept pfn changes in set_pte_at() without the required break-before-make sequence, attempt to dump all instructions on unhandled kernel faults. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEE5RElWfyWxS+3PLO2a9axLQDIXvEFAmP0/QsACgkQa9axLQDI XvG+gA/+JDVEH9wRzAIZvbp9hSuohPc48xgAmIMP1eiVB0/5qeRjYAJwS33H0rXS BPC2kj9IBy/eQeM9ICg0nFd0zYznSVacITqe6NrqeJ1F+ftS4rrHdfxd+J7kIoCs V2L8e+BJvmHdhmNV2qMAgJdGlfxfQBA7fv2cy52HKYcouoOh1AUVR/x+yXVXAsCd qJP3+dlUKccgm/oc5unEC1eZ49u8O+EoasqOyfG6K5udMgzhEX3K6imT9J3hw0WT UjstYkx5uGS/prUrRCQAX96VCHoZmzEDKtQuHkHvQXEYXsYPF3ldbR2CziNJnHe7 QfSkjJlt8HAtExA+BkwEe9i0MQO/2VF5qsa2e4fA6l7uqGu3LOtS/jJd23C9n9fR Id8aBMeN6S8+MjqRA9L2uf4t6e4ISEHoG9ZRdc4WOwloxEEiJoIeun+7bHdOSZLj AFdHFCz4NXiiwC0UP0xPDI2YeCLqt5np7HmnrUqwzRpVO8UUagiJD8TIpcBSjBN9 J68eidenHUW7/SlIeaMKE2lmo8AUEAJs9AorDSugF19/ThJcQdx7vT2UAZjeVB3j 1dbbwajnlDOk/w8PQC4thFp5/MDlfst0htS3WRwa+vgkweE2EAdTU4hUZ8qEP7FQ smhYtlT1xUSTYDTqoaG/U2OWR6/UU79wP0jgcOsHXTuyYrtPI/Q= =VmXL -----END PGP SIGNATURE----- Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux Pull arm64 updates from Catalin Marinas: - Support for arm64 SME 2 and 2.1.

dax/hmem: Move hmem device registration to dax_hmem.ko
In preparation for the CXL region driver to take over the responsibility of registering device-dax instances for CXL regions, move the registration of "hmem" devices to dax_hmem.ko. Previously the builtin component of this enabling (drivers/dax/hmem/device.o) would register platform devices for each address range and trigger the dax_hmem.ko module to load and attach device-dax instances to those devices. Now, the ranges are collected from the HMAT and EFI memory map walking, but the device creation is deferred. A new "hmem_platform" device is created which triggers dax_hmem.ko to load and register the platform devices.

ACPI: PMIC: Add comments with DSDT power opregion field names
The DSDTs of CHT devices using the Dollar Cove TI PMIC, all use LDO1 - LDO14 names for the DSDT power opregion field names. Add comments with these fields to make it easier to see which PMIC registers are being set by ACPI code using these. Note that LDO4 is missing and the mapped registers jump from 0x43 to 0x45 to match. This matches with how the fields are declared in the DSDT where LDO4 is skipped too. Note there is no hole in the field addresses, LDO4 is simply just not defined on either side.

ACPI: NFIT: fix a potential deadlock during NFIT teardown
Lockdep reports that acpi_nfit_shutdown() may deadlock against an opportune acpi_nfit_scrub(). acpi_nfit_scrub () is run from inside a 'work' and therefore has already acquired workqueue-internal locks. It also acquiires acpi_desc->init_mutex. acpi_nfit_shutdown() first acquires init_mutex, and was subsequently attempting to cancel any pending workqueue items. This reversed locking order causes a potential deadlock: ====================================================== WARNING: possible circular locking dependency detected 6.2.0-rc3 #116 Tainted: G O N ------------------------------------------------------ libndctl/1958 is trying to acquire lock: ffff888129b461c0 ((work_completion)(&(&acpi_desc->dwork)->work)){+.+.}-{0:0}, at: __flush_work+0x43/0x450 but task is already holding lock: ffff888129b460e8 (&acpi_desc->init_mutex){+.+.}-{3:3}, at: acpi_nfit_shutdown+0x87/0xd0 [nfit] which lock already depends on the new lock. ... Possible unsafe locking scenario: CPU0 CPU1 ---- ---- lock(&acpi_desc->init_mutex); lock((work_completion)(&(&acpi_desc->dwork)->work)); lock(&acpi_desc->init_mutex); lock((work_completion)(&(&acpi_desc->dwork)->work)); *** DEADLOCK *** Since the workqueue manipulation is protected by its own internal locking, the cancellation of pending work doesn't need to be done under acpi_desc->init_mutex. Move cancel_delayed_work_sync() outside the init_mutex to fix the deadlock. Any work that starts after acpi_nfit_shutdown() drops the lock will see ARS_CANCEL, and the cancel_delayed_work_sync() will safely flush it out.

ACPI: video: Fix apple gmux detection
Some apple laptop models have an ACPI device with a HID of APP000B
and that device has an IO resource (so it does not describe the new
unsupported MMIO based gmux type), but there actually is no gmux
in the laptop at all.
The gmux_probe() function of the actual apple-gmux driver has code
to detect this, this code has been factored out into a new
apple_gmux_detect() helper in apple-gmux.h.
Use this new function to fix acpi_video_get_backlight_type() wrongly
returning apple_gmux as type on the following laptops:

ACPI: Don't build ACPICA with '-Os'
The ACPICA code has been built with '-Os' since the beginning of git history, though there's no explanatory comment as to why. This is unfortunate as GCC drops the alignment specificed by '-falign-functions=N' when '-Os' is used, as reported in GCC bug 88345: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=88345 This prevents CONFIG_FUNCTION_ALIGNMENT and CONFIG_DEBUG_FORCE_FUNCTION_ALIGN_64B from having their expected effect on the ACPICA code. This is doubly unfortunate as in subsequent patches arm64 will depend upon CONFIG_FUNCTION_ALIGNMENT for its ftrace implementation. Drop the '-Os' flag when building the ACPICA code. With this removed, the code builds cleanly and works correctly in testing so far. I've tested this by selecting CONFIG_DEBUG_FORCE_FUNCTION_ALIGN_64B=y, building and booting a kernel using ACPI, and looking for misaligned text symbols: * arm64: Before, v6.2-rc3: # uname -rm 6.2.0-rc3 aarch64 # grep ' [Tt] ' /proc/kallsyms | grep -iv '[048c]0 [Tt] ' | wc -l 5009 Before, v6.2-rc3 + fixed __cold: # uname -rm 6.2.0-rc3-00001-g2a2bedf8bfa9 aarch64 # grep ' [Tt] ' /proc/kallsyms | grep -iv '[048c]0 [Tt] ' | wc -l 919 After: # uname -rm 6.2.0-rc3-00002-g267bddc38572 aarch64 # grep ' [Tt] ' /proc/kallsyms | grep -iv '[048c]0 [Tt] ' | wc -l 323 # grep ' [Tt] ' /proc/kallsyms | grep -iv '[048c]0 [Tt] ' | grep acpi | wc -l 0 * x86_64: Before, v6.2-rc3: # uname -rm 6.2.0-rc3 x86_64 # grep ' [Tt] ' /proc/kallsyms | grep -iv '[048c]0 [Tt] ' | wc -l 11537 Before, v6.2-rc3 + fixed __cold: # uname -rm 6.2.0-rc3-00001-g2a2bedf8bfa9 x86_64 # grep ' [Tt] ' /proc/kallsyms | grep -iv '[048c]0 [Tt] ' | wc -l 2805 After: # uname -rm 6.2.0-rc3-00002-g267bddc38572 x86_64 # grep ' [Tt] ' /proc/kallsyms | grep -iv '[048c]0 [Tt] ' | wc -l 1357 # grep ' [Tt] ' /proc/kallsyms | grep -iv '[048c]0 [Tt] ' | grep acpi | wc -l 0 With the patch applied, the remaining unaligned text labels are a combination of static call trampolines and labels in assembly, which can be dealt with in subsequent patches.

ACPI: video: Add backlight=native DMI quirk for Asus U46E
The Asus U46E backlight tables have a set of interesting problems:
1. Its ACPI tables do make _OSI ("Windows 2012") checks, so
acpi_osi_is_win8() should return true.
But the tables have 2 sets of _OSI calls, one from the usual global
_INI method setting a global OSYS variable and a second set of _OSI
calls from a MSOS method and the MSOS method is the only one calling
_OSI ("Windows 2012").
The MSOS method only gets called in the following cases:
1. From some Asus specific WMI methods
2. From _DOD, which only runs after acpi_video_get_backlight_type()
has already been called by the i915 driver
3. From other ACPI video bus methods which never run (see below)
4. From some EC query callbacks
So when i915 calls acpi_video_get_backlight_type() MSOS has never run
and acpi_osi_is_win8() returns false, so acpi_video_get_backlight_type()
returns acpi_video as the desired backlight type, which causes
the intel_backlight device to not register.
2. _DOD effectively does this:
Return (Package (0x01)
{
0x0400
})
causing acpi_video_device_in_dod() to return false, which causes
the acpi_video backlight device to not register.
Leaving the user with no backlight device at all. Note that before 6.1.y
the i915 driver would register the intel_backlight device unconditionally
and since that then was the only backlight device userspace would use that.
Add a backlight=native DMI quirk for this special laptop to restore
the old (and working) behavior of the intel_backlight device registering.

ACPI: video: Add backlight=native DMI quirk for HP EliteBook 8460p
The HP EliteBook 8460p predates Windows 8, so it defaults to using
acpi_video# for backlight control.
Starting with the 6.1.y kernels the native radeon_bl0 backlight is hidden
in this case instead of relying on userspace preferring acpi_video# over
native backlight devices.
It turns out that for the acpi_video# interface to work on
the HP EliteBook 8460p, the brightness needs to be set at least once
through the native interface, which now no longer is done breaking
backlight control.
The native interface however always works without problems, so add
a quirk to use native backlight on the EliteBook 8460p to fix this.

cacheinfo and arch_topology updates for v6.3
The main change is to build the cache topology information for all the CPUs from the primary CPU. Currently the cacheinfo for secondary CPUs is created during the early boot on the respective CPU itself. Preemption and interrupts are disabled at this stage. On PREEMPT_RT kernels, allocating memory and even parsing the PPTT table for ACPI based systems triggers a: 'BUG: sleeping function called from invalid context' To prevent this bug, the cacheinfo is now allocated from the primary CPU when preemption and interrupts are enabled and before booting secondary CPUs. The cache levels/leaves are computed from DT/ACPI PPTT information only, without relying on any architecture specific mechanism if done so early. The other minor change included here is to handle shared caches at different levels when not all the CPUs on the system have the same cache hierarchy. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEunHlEgbzHrJD3ZPhAEG6vDF+4pgFAmPKg60ACgkQAEG6vDF+ 4pi91hAAoSluqjbUHzzCW+OIIjKAAvQrAw6bsKGvSpcUfYno1Lry+9y76L6TMYSy OPtiKGxcJyzhdlCwIpJzgaX9nTz7uiu70euNZiAp11XA2KlphtLoI3TMUa60jD4i ZGfn9UiAp719Vog5m3CmZXjHZ6drI0HloL8ZWTl4VDATUu5pfcx4uYPT2o63Xc62 k5QglaRJWFhFAJ+R6R9vQS2zfeMI9xvehl72445wb8pxxPW2f91dvBhJqJgKlziw gHKx+D1DnpAUd+v+7HAEmzjXKlY6JnQybmBHmRayllVAa8kGUtvhTcBlRGNsNBzR m7VBFKq+eSk7VgxOgka1qXVtHUrlaEWf5qWnG+w4XEiE1VgzNagjaFRaGQQneKI/ z3yNKG8Xjp+3BdSz0pUDJVEWFnnjueAUEh6/xODEXnWdX166abQZslLIHCvmcnM8 q7blasuj2mxyCZFC1tyK9WHI7/KCe0cmHbdau3qs0j9bvhzfdB3DwMLsdRjXQTOv 8FVX0Z5EKY9/bW2oqCg/mb3KOWbmFX2ZHho4cds3IV+9GGB8JkD/6b8vpGejmmx2 E2vInzhP3gLd9WiWQWDjg4+aklE29P/nDAA8BSPnW3TtEGAFJMZZQRgNlCZnBW56 Tx2/lE0VD5/UX+1MqSFGchi+KEX3mcZykcra9VNt+uZH26a8gBE= =nH4b -----END PGP SIGNATURE----- Merge tag 'archtopo-cacheinfo-updates-6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into driver-core-next Sudeep writes: "cacheinfo and arch_topology updates for v6.3 The main change is to build the cache topology information for all the CPUs from the primary CPU.
