ACPI: Add a context argument for table parsing handlers
In preparation for drivers reusing the core table parsing infrastructure, arrange for handlers to take a context argument. This allows driver table parsing to wrap ACPI table entries in driver-specific data. The first consumer of this infrastructure is the CEDT parsing that happens in the cxl_acpi driver, add a conditional (CONFIG_ACPI_TABLE_LIB=y) export of a acpi_table_parse_cedt() helper for this case.

ACPI: Keep sub-table parsing infrastructure available for modules
The NFIT driver and now the CXL ACPI driver have both open-coded ACPI table parsing. Before another instance is added arrange for the core ACPI sub-table parsing to be optionally available to drivers via the CONFIG_ACPI_TABLE_LIB symbol. If no drivers select the symbol then the infrastructure reverts back to being tagged __init via the __init_or_acpilib annotation. For now, only tag the core sub-table routines and data that the CEDT parsing in the cxl_acpi driver would want to reuse, a CEDT parsing helper is added in a later change. Cc: "Rafael J.

topology: Represent clusters of CPUs within a die
Both ACPI and DT provide the ability to describe additional layers of
topology between that of individual cores and higher level constructs
such as the level at which the last level cache is shared.
In ACPI this can be represented in PPTT as a Processor Hierarchy
Node Structure [1] that is the parent of the CPU cores and in turn
has a parent Processor Hierarchy Nodes Structure representing
a higher level of topology.
For example Kunpeng 920 has 6 or 8 clusters in each NUMA node, and each
cluster has 4 cpus. All clusters share L3 cache data, but each cluster
has local L3 tag. On the other hand, each clusters will share some
internal system bus.

That means spreading tasks among clusters will bring more bandwidth
while packing tasks within one cluster will lead to smaller cache
synchronization latency. So both kernel and userspace will have
a chance to leverage this topology to deploy tasks accordingly to
achieve either smaller cache latency within one cluster or an even
distribution of load among clusters for higher throughput.
This patch exposes cluster topology to both kernel and userspace.
Libraried like hwloc will know cluster by cluster_cpus and related
sysfs attributes. PoC of HWLOC support at [2].
Note this patch only handle the ACPI case.
Special consideration is needed for SMT processors, where it is
necessary to move 2 levels up the hierarchy from the leaf nodes
(thus skipping the processor core level).
Note that arm64 / ACPI does not provide any means of identifying
a die level in the topology but that may be unrelate to the cluster
level.

"These include fixes of the recently introduced support for the
Platform Runtime Mechanism (PRM) feature, a new backlight quirk, a
suspend-to-idle wakeup fix for non-Intel platforms and a fix for the
AMBA bus resource list in /proc/iomem.
Specifics:
- Fix up the recently added Platform Runtime Mechanism (PRM) support
by correnting a couple of implementation mistakes in it and adding
a Kconfig help text to describe it (Aubrey Li, Rafael Wysocki).
- Add backlight quirk for Dell Vostro 3350 (Hans de Goede).
- Avoid spurious wakeups from suspend-to-idle on non-Intel platforms
by restricting special EC GPE handling to the Intel ones (Mario
Limonciello).
- Modify the AMBA bus support in ACPI to avoid adding using resource
names in /proc/iomem (Liguang Zhang)"

ACPI: PRM: implement OperationRegion handler for the PlatformRtMechanism subtype
Platform Runtime Mechanism (PRM) is a firmware interface that exposes
a set of binary executables that can either be called from the AML
interpreter or device drivers by bypassing the AML interpreter.
This change implements the AML interpreter path.
According to the specification [1], PRM services are listed in an
ACPI table called the PRMT. This patch parses module and handler
information listed in the PRMT and registers the PlatformRtMechanism
OpRegion handler before ACPI tables are loaded.
Each service is defined by a 16-byte GUID and called from writing a
26-byte ASL buffer containing the identifier to a FieldUnit object
defined inside a PlatformRtMechanism OperationRegion.
OperationRegion (PRMR, PlatformRtMechanism, 0, 26)
Field (PRMR, BufferAcc, NoLock, Preserve)
{
PRMF, 208 // Write to this field to invoke the OperationRegion Handler
}
The 26-byte ASL buffer is defined as the following:
Byte Offset Byte Length Description
=============================================================
0 1 PRM OperationRegion handler status
1 8 PRM service status
9 1 PRM command
10 16 PRM handler GUID
The ASL caller fills out a 26-byte buffer containing the PRM command
and the PRM handler GUID like so:
/* Local0 is the PRM data buffer */
Local0 = buffer (26){}
/* Create byte fields over the buffer */
CreateByteField (Local0, 0x9, CMD)
CreateField (Local0, 0x50, 0x80, GUID)
/* Fill in the command and data fields of the data buffer */
CMD = 0 // run command
GUID = ToUUID("xxxx-xx-xxx-xxxx")
/*
* Invoke PRM service with an ID that matches GUID and save the
* result.
*/
Local0 = (\_SB.PRMT.PRMF = Local0)
Byte offset 0 - 8 are written by the handler as a status passed back to AML
and used by ASL like so:
/* Create byte fields over the buffer */
CreateByteField (Local0, 0x0, PSTA)
CreateQWordField (Local0, 0x1, USTA)
In this ASL code, PSTA contains a status from the OperationRegion and
USTA contains a status from the PRM service.
The 26-byte buffer is recieved by acpi_platformrt_space_handler. This
handler will look at the command value and the handler guid and take
the approperiate actions.
Command value Action
=====================================================================
0 Run the PRM service indicated by the PRM handler
GUID (bytes 10-26)
1 Prevent PRM runtime updates from happening to the
service's parent module
2 Allow PRM updates from happening to the service's parent module
This patch enables command value 0.

ACPI: scan: Extend acpi_walk_dep_device_list()
The acpi_walk_dep_device_list() function is not as generic as its name implies, serving only to decrement the dependency count for each dependent device of the input. Extend it to accept a callback which can be applied to all the dependencies in acpi_dep_list. Replace all existing calls to the function with calls to a wrapper, passing a callback that applies the same dependency reduction.

ACPI: Add support for native USB4 control _OSC
ACPI 6.4 introduced a new _OSC capability that is used negotiate native connection manager support. Connection manager is the entity that is responsible for tunneling over the USB4 fabric. If the platform rejects the native access then firmware based connection manager is used. The new _OSC also includes a set of bits that can be used to disable certain tunnel types such as PCIe for security reasons for instance. This implements the new USB4 _OSC so that we try to negotiate native USB4 support if the Thunderbolt/USB4 (CONFIG_USB4) driver is enabled. Drivers can determine what was negotiated by checking two new variables exposed in this patch. Signed-off-by: Mika Westerberg <mika.westerberg@linux.intel.com> Reviewed-by: Rafael J.

ACPI: Make acpi_evaluate_dsm() prototype consistent
When compiling a driver which includes both include/linux/acpi.h and

ACPI: Let ACPI know we support Generic Initiator Affinity Structures
Until we tell ACPI that we support generic initiators, it will have to operate in fall back domain mode and all _PXM entries should be on existing non GI domains.

arm64: permit ACPI core to map kernel memory used for table overrides
Jonathan reports that the strict policy for memory mapped by the ACPI core breaks the use case of passing ACPI table overrides via initramfs. This is due to the fact that the memory type used for loading the initramfs in memory is not recognized as a memory type that is typically used by firmware to pass firmware tables. Since the purpose of the strict policy is to ensure that no AML or other ACPI code can manipulate any memory that is used by the kernel to keep its internal state or the state of user tasks, we can relax the permission check, and allow mappings of memory that is reserved and marked as NOMAP via memblock, and therefore not covered by the linear mapping to begin with.

ACPI: Remove side effect of partly creating a node in acpi_map_pxm_to_online_node()
While this function will only return an online node, it can have the side effect of partially creating a new node. The existing comments suggest this is intentional, but the usecases of this function are related to NFIT and HMAT parsing, neither of which should be able to define new nodes. One route by which the existing behaviour would cause a crash is to have a _PXM entry in ACPI DSDT attempt to place a device within this partly created proximity domain. A subsequent call to devm_kzalloc() or similar would result in an attempt to allocate memory on a node for which zone lists have not been set up and a NULL pointer dereference. Prevent such cases by switching to pxm_to_node() within acpi_map_pxm_to_online_node() which cannot cause a new node to be partly created. If one would previously have been created we now return NO_NUMA_NODE. Documentation updated to reflect this change.

ACPI/IORT: Add an input ID to acpi_dma_configure()
Some HW devices are created as child devices of proprietary busses, that have a bus specific policy defining how the child devices wires representing the devices ID are translated into IOMMU and IRQ controllers device IDs. Current IORT code provides translations for: - PCI devices, where the device ID is well identified at bus level as the requester ID (RID) - Platform devices that are endpoint devices where the device ID is retrieved from the ACPI object IORT mappings (Named components single mappings). A platform device is represented in IORT as a named component node For devices that are child devices of proprietary busses the IORT firmware represents the bus node as a named component node in IORT and it is up to that named component node to define in/out bus specific ID translations for the bus child devices that are allocated and created in a bus specific manner. In order to make IORT ID translations available for proprietary bus child devices, the current ACPI (and IORT) code must be augmented to provide an additional ID parameter to acpi_dma_configure() representing the child devices input ID. This ID is bus specific and it is retrieved in bus specific code. By adding an ID parameter to acpi_dma_configure(), the IORT code can map the child device ID to an IOMMU stream ID through the IORT named component representing the bus in/out ID mappings.

drivers/acpi: Add new macro ACPI_DECLARE_SUBTABLE_PROBE_ENTRY
In an effort to enable -Wcast-function-type in the top-level Makefile to support Control Flow Integrity builds, there are the need to remove all the function callback casts. To do this, create a new macro called ACPI_DECLARE_SUBTABLE_PROBE_ENTRY to initialize the acpi_probe_entry struct using the probe_subtbl field instead of the probe_table field. This is a previous work to be able to modify the IRQCHIP_ACPI_DECLARE macro to use this new defined macro. Even though these two commented fields are part of a union, this is necessary to avoid function cast mismatches. That is, due to the IRQCHIP_ACPI_DECLARE invocations use as last parameter a function with the protoype "int (*func)(struct acpi_subtable_header *, const unsigned long)" it's necessary that this macro initialize the probe_subtbl field of the acpi_probe_entry struct and not the probe_table field.

PCI/DPC: Add Error Disconnect Recover (EDR) support
Error Disconnect Recover (EDR) is a feature that allows ACPI firmware to
notify OSPM that a device has been disconnected due to an error condition
(ACPI v6.3, sec 5.6.6). OSPM advertises its support for EDR on PCI devices
via _OSC (see [1], sec 4.5.1, table 4-4). The OSPM EDR notify handler
should invalidate software state associated with disconnected devices and
may attempt to recover them. OSPM communicates the status of recovery to
the firmware via _OST (sec 6.3.5.2).
For PCIe, firmware may use Downstream Port Containment (DPC) to support
EDR. Per [1], sec 4.5.1, table 4-6, even if firmware has retained control
of DPC, OSPM may read/write DPC control and status registers during the EDR
notification processing window, i.e., from the time it receives an EDR
notification until it clears the DPC Trigger Status.
Note that per [1], sec 4.5.1 and 4.5.2.4,
1. If the OS supports EDR, it should advertise that to firmware by
setting OSC_PCI_EDR_SUPPORT in _OSC Support.
2. If the OS sets OSC_PCI_EXPRESS_DPC_CONTROL in _OSC Control to request
control of the DPC capability, it must also set OSC_PCI_EDR_SUPPORT in
_OSC Support.
Add an EDR notify handler to attempt recovery.

ACPI: NUMA: Up-level "map to online node" functionality
The acpi_map_pxm_to_online_node() helper is used to find the closest online node to a given proximity domain. This is used to map devices in a proximity domain with no online memory or cpus to the closest online node and populate a device's 'numa_node' property. The numa_node property allows applications to be migrated "close" to a resource. In preparation for providing a generic facility to optionally map an address range to its closest online node, or the node the range would represent were it to be onlined (target_node), up-level the core of acpi_map_pxm_to_online_node() to a generic mm/numa helper.

The intel_idle driver will be modified to use ACPI _CST subsequently and it will need to call acpi_processor_evaluate_cst(), so move that function to acpi_processor.c so that it is always present (which is required by intel_idle) and export it to modules to allow the ACPI processor driver (which is modular) to call it.

Merge branch 'next-lockdown' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security
Pull kernel lockdown mode from James Morris:
"This is the latest iteration of the kernel lockdown patchset, from
Matthew Garrett, David Howells and others.
From the original description:
This patchset introduces an optional kernel lockdown feature,
intended to strengthen the boundary between UID 0 and the kernel.
When enabled, various pieces of kernel functionality are restricted.
Applications that rely on low-level access to either hardware or the
kernel may cease working as a result - therefore this should not be
enabled without appropriate evaluation beforehand.
The majority of mainstream distributions have been carrying variants
of this patchset for many years now, so there's value in providing a
doesn't meet every distribution requirement, but gets us much closer
to not requiring external patches.
There are two major changes since this was last proposed for mainline:
- Separating lockdown from EFI secure boot. Background discussion is
covered here: https://lwn.net/Articles/751061/
- Implementation as an LSM, with a default stackable lockdown LSM
module. This allows the lockdown feature to be policy-driven,
rather than encoding an implicit policy within the mechanism.
The new locked_down LSM hook is provided to allow LSMs to make a
policy decision around whether kernel functionality that would allow
tampering with or examining the runtime state of the kernel should be
permitted.
The included lockdown LSM provides an implementation with a simple
policy intended for general purpose use. This policy provides a coarse
level of granularity, controllable via the kernel command line:
lockdown={integrity|confidentiality}
Enable the kernel lockdown feature. If set to integrity, kernel features
that allow userland to modify the running kernel are disabled. If set to
confidentiality, kernel features that allow userland to extract
confidential information from the kernel are also disabled.
This may also be controlled via /sys/kernel/security/lockdown and
overriden by kernel configuration.
New or existing LSMs may implement finer-grained controls of the
lockdown features. Refer to the lockdown_reason documentation in
include/linux/security.h for details.
The lockdown feature has had signficant design feedback and review
across many subsystems. This code has been in linux-next for some
weeks, with a few fixes applied along the way.

a fair few headline features which I've noted both in the tag and also
in the merge commits when I pulled everything together.
The part I'm most pleased with is that we had 35 contributors this
time around, which feels like a big jump from the usual small group of
core arm64 arch developers. Hopefully they all enjoyed it so much that
they'll continue to contribute, but we'll see.
It's probably worth highlighting that we've pulled in a branch from
the risc-v folks which moves our CPU topology code out to where it can
be shared with others.

acpi: Ignore acpi_rsdp kernel param when the kernel has been locked down
This option allows userspace to pass the RSDP address to the kernel, which makes it possible for a user to modify the workings of hardware. Reject the option when the kernel is locked down. This requires some reworking of the existing RSDP command line logic, since the early boot code also makes use of a command-line passed RSDP when locating the SRAT table before the lockdown code has been initialised. This is achieved by separating the command line RSDP path in the early boot code from the generic RSDP path, and then copying the command line RSDP into boot params in the kernel proper if lockdown is not enabled. If lockdown is enabled and an RSDP is provided on the command line, this will only be used when parsing SRAT (which shouldn't permit kernel code execution) and will be ignored in the rest of the kernel.

ACPI: PM: Set up EC GPE for system wakeup from drivers that need it
The EC GPE needs to be set up for system wakeup only if there is a driver depending on it, either intel-hid or intel-vbtn, bound to a button device that is expected to wake up the system from sleep (such as the power button on some Dell systems, like the XPS13 9360). It doesn't need to be set up for waking up the system from sleep in any other cases and whether or not it is expected to wake up the system from sleep doesn't depend on whether or not the LPS0 device is present in the ACPI namespace. For this reason, rearrange the ACPI suspend-to-idle code to make the drivers depending on the EC GPE wakeup take care of setting it up and decouple that from the LPS0 device handling. While at it, make intel-hid and intel-vbtn prepare for system wakeup only if they are allowed to wake up the system from sleep by user space (via sysfs). [Note that acpi_ec_mark_gpe_for_wake() and acpi_ec_set_gpe_wake_mask() are there to prevent the EC GPE from being disabled by the acpi_enable_all_wakeup_gpes() call in acpi_s2idle_prepare(), so on systems with either intel-hid or intel-vbtn this change doesn't affect any interactions with the hardware or platform firmware.] Signed-off-by: Rafael J.

polarity = polarity ? ACPI_ACTIVE_LOW : ACPI_ACTIVE_HIGH;

platform-drivers-x86 for v5.3-1
ASUS WMI driver got a big refactoring in order to support the TUF Gaming laptops. Besides that, the regression with backlight being permanently off on various EeePC laptops has been fixed. Accelerometer on HP ProBook 450 G0 shows wrong measurements due to X axis being inverted. This has been fixed. Intel PMC core driver has been extended to be ACPI enumerated if the DSDT provides device with _HID "INT33A1". This allows to convert the driver to be pure platform and support new hardware purely based on ACPI DSDT. From now on the Intel Speed Select Technology is supported thru a corresponding driver. This driver provides an access to the features of the ISST, such as Performance Profile, Core Power, Base frequency and Turbo Frequency. Mellanox platform drivers has been refactored and now extended to support more systems, including new coming ones. The OLPC XO-1.75 platform is now supported. CB4063 Beckhoff Automation board is using PMC clocks, provided via pmc_atom driver, for ethernet controllers in a way that they can't be managed by the clock driver. The quirk has been extended to cover this case. Touchscreen on Chuwi Hi10 Plus tablet has been enabled. Meanwhile the information of Chuwi Hi10 Air has been fixed to cover more models based on the same platform. Xiaomi notebooks have WMI interface enabled. Thus, the driver to support it has been provided. It required some extension of the generic WMI library, which allows to propagate opaque context to the ->probe() of the individual drivers. This release includes debugfs clean up from Greg KH for several drivers that drop return code check and make debugfs absence or failure non-fatal. Miscellaneous fixes here and there, mostly for Acer WMI and various Intel drivers. The listed below commits are duplicated due to previously pushed fixes in v5.2 cycle: - |

ACPI: PM: Introduce "poweroff" callbacks for ACPI PM domain and LPSS
In general, it is not correct to call pm_generic_suspend(),
pm_generic_suspend_late() and pm_generic_suspend_noirq() during the
hibernation's "poweroff" transition, because device drivers may
provide special callbacks to be invoked then and the wrappers in
question cause system suspend callbacks to be run. Unfortunately,
that happens in the ACPI PM domain and ACPI LPSS.
To address this potential issue, introduce "poweroff" callbacks
for the ACPI PM and LPSS that will use pm_generic_poweroff(),
pm_generic_poweroff_late() and pm_generic_poweroff_noirq() as
appropriate.

ACPI: PM: Simplify and fix PM domain hibernation callbacks
First, after a previous change causing all runtime-suspended devices
in the ACPI PM domain (and ACPI LPSS devices) to be resumed before
creating a snapshot image of memory during hibernation, it is not
necessary to worry about the case in which them might be left in
runtime-suspend any more, so get rid of the code related to that from
ACPI PM domain and ACPI LPSS hibernation callbacks.
Second, it is not correct to use pm_generic_resume_early() and
acpi_subsys_resume_noirq() in hibernation "restore" callbacks (which
currently happens in the ACPI PM domain and ACPI LPSS), so introduce
proper _restore_late and _restore_noirq callbacks for the ACPI PM
domain and ACPI LPSS.

ACPI/PPTT: Add function to return ACPI 6.3 Identical tokens
ACPI 6.3 adds a flag to indicate that child nodes are all identical cores. This is useful to authoritatively determine if a set of (possibly offline) cores are identical or not. Since the flag doesn't give us a unique id we can generate one and use it to create bitmaps of sibling nodes, or simply in a loop to determine if a subset of cores are identical. Acked-by: Rafael J.

acpi/irq: Implement helper to create hierachical domains
ACPI permits arbitrary producer->consumer interrupt links to be
described in AML, which means a topology such as the following
is perfectly legal:
Device (EXIU) {
Name (_HID, "SCX0008")
Name (_UID, Zero)
Name (_CRS, ResourceTemplate () {
...
})
}
Device (GPIO) {
Name (_HID, "SCX0007")
Name (_UID, Zero)
Name (_CRS, ResourceTemplate () {
Memory32Fixed (ReadWrite, SYNQUACER_GPIO_BASE, SYNQUACER_GPIO_SIZE)
Interrupt (ResourceConsumer, Edge, ActiveHigh, ExclusiveAndWake, 0, "\\_SB.EXIU") {
7,
}
})
...
}
The EXIU in this example is the external interrupt unit as can be found
on Socionext SynQuacer based platforms, which converts a block of 32 SPIs
from arbitrary polarity/trigger into level-high, with a separate set
of config/mask/unmask/clear controls.
The existing DT based driver in drivers/irqchip/irq-sni-exiu.c models
this as a hierarchical domain stacked on top of the GIC's irqdomain.
Since the GIC is modeled as a DT node as well, obtaining a reference
to this irqdomain is easily done by going through the parent link.
On ACPI systems, however, the GIC is not modeled as an object in the
namespace, and so device objects cannot refer to it directly. So in
order to obtain the irqdomain reference when driving the EXIU in ACPI
mode, we need a helper that implicitly grabs the default domain as the
parent of the hierarchy for interrupts allocated out of the global GSI
pool.

acpi: Create subtable parsing infrastructure
Parsing entries in an ACPI table had assumed a generic header structure. There is no standard ACPI header, though, so less common layouts with different field sizes required custom parsers to go through their subtable entry list. Create the infrastructure for adding different table types so parsing the entries array may be more reused for all ACPI system tables and the common code doesn't need to be duplicated.

Pull device-dax updates from Dan Williams:
"New device-dax infrastructure to allow persistent memory and other
"reserved" / performance differentiated memories, to be assigned to
the core-mm as "System RAM".
Some users want to use persistent memory as additional volatile
memory. They are willing to cope with potential performance
differences, for example between DRAM and 3D Xpoint, and want to use
typical Linux memory management apis rather than a userspace memory
allocator layered over an mmap() of a dax file. The administration
model is to decide how much Persistent Memory (pmem) to use as System
RAM, create a device-dax-mode namespace of that size, and then assign
it to the core-mm. The rationale for device-dax is that it is a
generic memory-mapping driver that can be layered over any "special
purpose" memory, not just pmem. On subsequent boots udev rules can be
used to restore the memory assignment.
One implication of using pmem as RAM is that mlock() no longer keeps
data off persistent media. For this reason it is recommended to enable
NVDIMM Security (previously merged for 5.0) to encrypt pmem contents
at rest. We considered making this recommendation an actively enforced
requirement, but in the end decided to leave it as a distribution /
administrator policy to allow for emulation and test environments that
lack security capable NVDIMMs.
Summary:
- Replace the /sys/class/dax device model with /sys/bus/dax, and
include a compat driver so distributions can opt-in to the new ABI.
- Allow for an alternative driver for the device-dax address-range
- Introduce the 'kmem' driver to hotplug / assign a device-dax
address-range to the core-mm.
- Arrange for the device-dax target-node to be onlined so that the
newly added memory range can be uniquely referenced by numa apis"
NOTE! I'm not entirely happy with the whole "PMEM as RAM" model because
we currently have special - and very annoying rules in the kernel about
accessing PMEM only with the "MC safe" accessors, because machine checks
inside the regular repeat string copy functions can be fatal in some
(not described) circumstances.
And apparently the PMEM modules can cause that a lot more than regular
RAM. The argument is that this happens because PMEM doesn't necessarily
get scrubbed at boot like RAM does, but that is planned to be added for
the user space tooling.
Quoting Dan from another email:
"The exposure can be reduced in the volatile-RAM case by scanning for
and clearing errors before it is onlined as RAM. The userspace tooling
for that can be in place before v5.1-final. There's also runtime
notifications of errors via acpi_nfit_uc_error_notify() from
background scrubbers on the DIMM devices. With that mechanism the
kernel could proactively clear newly discovered poison in the volatile
case, but that would be additional development more suitable for v5.2.
I understand the concern, and the need to highlight this issue by
tapping the brakes on feature development, but I don't see PMEM as RAM
making the situation worse when the exposure is also there via DAX in
the PMEM case. Volatile-RAM is arguably a safer use case since it's
possible to repair pages where the persistent case needs active
application coordination"

acpi/nfit, device-dax: Identify differentiated memory with a unique numa-node
Persistent memory, as described by the ACPI NFIT (NVDIMM Firmware Interface Table), is the first known instance of a memory range described by a unique "target" proximity domain. Where "initiator" and "target" proximity domains is an approach that the ACPI HMAT (Heterogeneous Memory Attributes Table) uses to described the unique performance properties of a memory range relative to a given initiator (e.g. CPU or DMA device). Currently the numa-node for a /dev/pmemX block-device or /dev/daxX.Y char-device follows the traditional notion of 'numa-node' where the attribute conveys the closest online numa-node. That numa-node attribute is useful for cpu-binding and memory-binding processes *near* the device. However, when the memory range backing a 'pmem', or 'dax' device is onlined (memory hot-add) the memory-only-numa-node representing that address needs to be differentiated from the set of online nodes. In other words, the numa-node association of the device depends on whether you can bind processes *near* the cpu-numa-node in the offline device-case, or bind process *on* the memory-range directly after the backing address range is onlined. Allow for the case that platform firmware describes persistent memory with a unique proximity domain, i.e. when it is distinct from the proximity of DRAM and CPUs that are on the same socket. Plumb the Linux numa-node translation of that proximity through the libnvdimm region device to namespaces that are in device-dax mode. With this in place the proposed kmem driver [1] can optionally discover a unique numa-node number for the address range as it transitions the memory from an offline state managed by a device-driver to an online memory range managed by the core-mm.

ACPI / property: Allow multiple property compatible _DSD entries
It is possible to have _DSD entries where the data is compatible with
device properties format but are using different GUID for various reasons.
In addition to that there can be many such _DSD entries for a single device
such as for PCIe root port used to host a Thunderbolt hierarchy:
Scope (\_SB.PCI0.RP21)
{
Name (_DSD, Package () {
ToUUID ("6211e2c0-58a3-4af3-90e1-927a4e0c55a4"),
Package () {
Package () {"HotPlugSupportInD3", 1}
},
ToUUID ("efcc06cc-73ac-4bc3-bff0-76143807c389"),
Package () {
Package () {"ExternalFacingPort", 1},
Package () {"UID", 0 }
}
})
}
More information about these new _DSD entries can be found in:
https://docs.microsoft.com/en-us/windows-hardware/drivers/pci/dsd-for-pcie-root-ports
To make these available for drivers via unified device property APIs,
modify ACPI property core so that it supports multiple _DSD entries
organized in a linked list. We also store GUID of each _DSD entry in struct
acpi_device_properties in case there is need to differentiate between
entries. The supported GUIDs are then listed in prp_guids array.

ACPI: Convert ACPI reference args to generic fwnode reference args
Convert all users of struct acpi_reference_args to more generic
fwnode_reference_args. This will
1) avoid an ACPI specific references to device nodes with integer
arguments as well as
2) allow making references to nodes other than device nodes in ACPI.
As a by-product, convert the fwnode interger arguments to u64. The
arguments were 64-bit integers on ACPI but the fwnode arguments were
just 32-bit.

acpi: Add helper for deactivating memory region
Sometimes memory resource may be overlapping with
SystemMemory Operation Region by design, for example if the
memory region is used as a mailbox for communication with a
firmware in the system. One occasion of such mailboxes is
USB Type-C Connector System Software Interface (UCSI).
With regions like that, it is important that the driver is
able to map the memory with the requirements it has. For
example, the driver should be allowed to map the memory as
non-cached memory. However, if the operation region has been
accessed before the driver has mapped the memory, the memory
has been marked as write-back by the time the driver is
loaded. That means the driver will fail to map the memory
if it expects non-cached memory.
To work around the problem, introducing helper that the
drivers can use to temporarily deactivate (unmap)
SystemMemory Operation Regions that overlap with their
IO memory.

- ACPI PPTT (Processor Properties Topology Table) parsing support and
enable the feature for arm64
- Report signal frame size to user via auxv (AT_MINSIGSTKSZ). The
primary motivation is Scalable Vector Extensions which requires more
space on the signal frame than the currently defined MINSIGSTKSZ
- ARM perf patches: allow building arm-cci as module, demote dev_warn()
to dev_dbg() in arm-ccn event_init(), miscellaneous cleanups
- cmpwait() WFE optimisation to avoid some spurious wakeups
- L1_CACHE_BYTES reverted back to 64 (for performance reasons that have
to do with some network allocations) while keeping ARCH_DMA_MINALIGN
to 128. cache_line_size() returns the actual hardware Cache Writeback

ACPI/PPTT: Add Processor Properties Topology Table parsing
ACPI 6.2 adds a new table, which describes how processing units are related to each other in tree like fashion. Caches are also sprinkled throughout the tree and describe the properties of the caches in relation to other caches and processing units. Add the code to parse the cache hierarchy and report the total number of levels of cache for a given core using acpi_find_last_cache_level() as well as fill out the individual cores cache information with cache_setup_acpi() once the cpu_cacheinfo structure has been populated by the arch specific code. An additional patch later in the set adds the ability to report peers in the topology using find_acpi_cpu_topology() to report a unique ID for each processing unit at a given level in the tree. These unique id's can then be used to match related processing units which exist as threads, within a given package, etc. Tested-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Tested-by: Vijaya Kumar K <vkilari@codeaurora.org> Tested-by: Xiongfeng Wang <wangxiongfeng2@huawei.com> Tested-by: Tomasz Nowicki <Tomasz.Nowicki@cavium.com> Acked-by: Sudeep Holla <sudeep.holla@arm.com> Acked-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Acked-by: Rafael J.

PM / Domains: Allow a better error handling of dev_pm_domain_attach()
The callers of dev_pm_domain_attach() currently checks the returned error code for -EPROBE_DEFER and needs to ignore other error codes. This is an unnecessary limitation, which also leads to a rather strange behaviour in the error path. Address this limitation, by changing the return codes from acpi_dev_pm_attach() and genpd_dev_pm_attach(). More precisely, let them return 0, when no PM domain is needed for the device and then return 1, in case the device was successfully attached to its PM domain. In this way, dev_pm_domain_attach(), gets a better understanding of what happens in the attach attempts and also allowing its caller to better act on real errors codes.

PCI/ACPI: Request LTR control from platform before using it
Per the PCI Firmware spec r3.2, sec 4.5, an ACPI-based OS should use _OSC to request control of Latency Tolerance Reporting (LTR) before using it. Request control of LTR, and if the platform does not grant control, don't use it. N.B. If the hardware supports LTR and the ASPM L1.2 substate but the BIOS doesn't support LTR in _OSC, we previously would enable ASPM L1.2. This patch will prevent us from enabling ASPM L1.2 in that case. It does not prevent us from enabling PCI-PM L1.2, since that doesn't depend on LTR. See PCIe r40, sec 5.5.1, for the L1 PM substate entry conditions. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> Reviewed-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com> |

ACPI: SPCR: Make SPCR available to x86
SPCR is currently only enabled or ARM64 and x86 can use SPCR to setup an early console. General fixes include updating Documentation & Kconfig (for x86), updating comments, and changing parse_spcr() to acpi_parse_spcr(), and earlycon_init_is_deferred to earlycon_acpi_spcr_enable to be more descriptive. On x86, many systems have a valid SPCR table but the table version is not 2 so the table version check must be a warning. On ARM64 when the kernel parameter earlycon is used both the early console and console are enabled. On x86, only the earlycon should be enabled by by default. Modify acpi_parse_spcr() to allow options for initializing the early console and console separately.

The is the bulk of GPIO changes for the v4.16 kernel cycle.
Core changes:
- Disallow open drain and open source flags to be set
simultaneously. This doesn't make electrical sense, and would
the hardware actually respond to this setting, the result
would be short circuit.
- ACPI GPIO has a new core infrastructure for handling quirks.
The quirks are there to deal with broken ACPI tables centrally
instead of pushing the work to individual drivers. In the world
of BIOS writers, the ACPI tables are perfect. Until they find a
mistake in it. When such a mistake is found, we can patch it
with a quirk. It should never happen, the problem is that it
happens. So we accomodate for it.
- Several documentation updates.
- Revert the patch setting up initial direction state from
reading the device. This was causing bad things for drivers
that can't read status on all its pins. It is only affecting
debugfs information quality.
- Label descriptors with the device name if no explicit label is
passed in.
- Pave the ground for transitioning SPI and regulators to use
GPIO descriptors by implementing some quirks in the device tree
GPIO parsing code.
New drivers:
- New driver for the Access PCIe IDIO 24 family.
Other:
- Major refactorings and improvements to the GPIO mockup driver
used for test and verification.
- Moved the AXP209 driver over to pin control since it gained a
pin control back-end. These patches will appear (with the same
hashes) in the pin control pull request as well.
- Convert the onewire GPIO driver w1-gpio to use descriptors.

Merge tag 'gpio-v4.16-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio
Pull GPIO updates from Linus Walleij:
"The is the bulk of GPIO changes for the v4.16 kernel cycle. It is
pretty calm this time around I think. I even got time to get to things
like starting to clean up header includes.
Core changes:
- Disallow open drain and open source flags to be set simultaneously.
This doesn't make electrical sense, and would the hardware actually
respond to this setting, the result would be short circuit.
- ACPI GPIO has a new core infrastructure for handling quirks. The
quirks are there to deal with broken ACPI tables centrally instead
of pushing the work to individual drivers. In the world of BIOS
writers, the ACPI tables are perfect. Until they find a mistake in
it. When such a mistake is found, we can patch it with a quirk. It
should never happen, the problem is that it happens. So we
accomodate for it.
- Several documentation updates.
- Revert the patch setting up initial direction state from reading
the device. This was causing bad things for drivers that can't read
status on all its pins. It is only affecting debugfs information
quality.
- Label descriptors with the device name if no explicit label is
passed in.
- Pave the ground for transitioning SPI and regulators to use GPIO
descriptors by implementing some quirks in the device tree GPIO
parsing code.
New drivers:
- New driver for the Access PCIe IDIO 24 family.
Other:
- Major refactorings and improvements to the GPIO mockup driver used
for test and verification.
- Moved the AXP209 driver over to pin control since it gained a pin
control back-end. These patches will appear (with the same hashes)
in the pin control pull request as well.
- Convert the onewire GPIO driver w1-gpio to use descriptors. This is
merged here since the W1 maintainers send very few pull requests
and he ACKed it.
- Start to clean up driver headers using <linux/gpio.h> to just use
<linux/gpio/driver.h> as appropriate"

device property: Introduce fwnode_irq_get()
Until now there were two very similar functions allowing to get Linux IRQ number from ACPI handle (acpi_irq_get()) and OF node (of_irq_get()). The first one appeared to be used only as a subroutine of platform_irq_get(), which (in the generic code) limited IRQ obtaining from _CRS method only to nodes associated to kernel's struct platform_device. This patch introduces a new helper routine - fwnode_irq_get(), which allows to get the IRQ number directly from the fwnode to be used as common for OF/ACPI worlds. It is usable not only for the parents fwnodes, but also for the child nodes comprising their own _CRS methods with interrupts description. In order to be able o satisfy compilation with !CONFIG_ACPI and also simplify the new code, introduce a helper macro (ACPI_HANDLE_FWNODE), with which it is possible to reach an ACPI handle directly from its fwnode.

ACPI: utils: Introduce acpi_dev_get_first_match_name()
Sometimes the user wants to have device name of the match rather than just checking if device present or not. To make life easier for such users introduce acpi_dev_get_first_match_name() helper based on code for acpi_dev_present(). For example, GPIO driver for Intel Merrifield needs to know the device name of pin control to be able to apply GPIO mapping table to the proper device. To be more consistent with the purpose rename struct acpi_dev_present_info -> struct acpi_dev_match_info acpi_dev_present_cb() -> acpi_dev_match_cb() in the utils.c file.

ACPI / PM: Make it possible to ignore the system sleep blacklist
The ACPI code supporting system transitions to sleep states uses
an internal blacklist to apply special handling to some machines
reported to behave incorrectly in some ways.
However, some entries of that blacklist cover problematic as well as
non-problematic systems, so give the users of the latter a chance to
ignore the blacklist and run their systems in the default way by
adding acpi_sleep=nobl to the kernel command line.
For example, that allows the users of Dell XPS13 9360 systems not
affected by the issue that caused the blacklist entry for this
machine to be added by commit

ACPI / PM: Take SMART_SUSPEND driver flag into account
Make the ACPI PM domain take DPM_FLAG_SMART_SUSPEND into account in its system suspend callbacks. [Note that the pm_runtime_suspended() check in acpi_dev_needs_resume() is an optimization, because if is not passed, all of the subsequent checks may be skipped and some of them are much more overhead in general.] Also use the observation that if the device is in runtime suspend at the beginning of the "late" phase of a system-wide suspend-like transition, its state cannot change going forward (runtime PM is disabled for it at that time) until the transition is over and the subsequent system-wide PM callbacks should be skipped for it (as they generally assume the device to not be suspended), so add checks for that in acpi_subsys_suspend_late/noirq() and acpi_subsys_freeze_late/noirq(). Moreover, if acpi_subsys_resume_noirq() is called during the subsequent system-wide resume transition and if the device was left in runtime suspend previously, its runtime PM status needs to be changed to "active" as it is going to be put into the full-power state going forward, so add a check for that too in there. In turn, if acpi_subsys_thaw_noirq() runs after the device has been left in runtime suspend, the subsequent "thaw" callbacks need to be skipped for it (as they may not work correctly with a suspended device), so set the power.direct_complete flag for the device then to make the PM core skip those callbacks. On top of the above, make the analogous changes in the acpi_lpss driver that uses the ACPI PM domain callbacks. Signed-off-by: Rafael J.

ACPI / LPIT: Add Low Power Idle Table (LPIT) support
Add functionality to read LPIT table, which provides: - Sysfs interface to read residency counters via /sys/devices/system/cpu/cpuidle/low_power_idle_cpu_residency_us /sys/devices/system/cpu/cpuidle/low_power_idle_system_residency_us Here the count "low_power_idle_cpu_residency_us" shows the time spent by CPU package in low power state. This is read via MSR interface, which points to MSR for PKG C10. Here the count "low_power_idle_system_residency_us" show the count the system was in low power state. This is read via MMIO interface. This is mapped to SLP_S0 residency on modern Intel systems. This residency is achieved only when CPU is in PKG C10 and all functional blocks are in low power state. It is possible that none of the above counters present or anyone of the counter present or all counters present. For example: On my Kabylake system both of the above counters present. After suspend to idle these counts updated and prints: 6916179 6998564 This counter can be read by tools like turbostat to display. Or it can be used to debug, if modern systems are reaching desired low power state. - Provides an interface to read residency counter memory address This address can be used to get the base address of PMC memory mapped IO. This is utilized by intel_pmc_core driver to print more debug information. In addition, to avoid code duplication to read iomem, removed the read of iomem from acpi_os_read_memory() in osl.c and made a common function acpi_os_read_iomem(). This new function is used for reading iomem in in both osl.c and acpi_lpit.c.

ACPI / PM: Combine two identical device resume routines
Notice that acpi_dev_runtime_resume() and acpi_dev_resume_early() are actually literally identical after some more-or-less recent changes, so rename acpi_dev_runtime_resume() to acpi_dev_resume(), use it everywhere instead of acpi_dev_resume_early() and drop the latter.

Device properties framework updates for v4.14-rc1
- Introduce fwnode operations for all of the separate types of
"firmware nodes" that can be handled by the device properties
framework and drop the type field from struct fwnode_handle
(Sakari Ailus, Arnd Bergmann).
- Make the device properties framework use const fwnode arguments
where possible (Sakari Ailus).
- Add a helper for the consolidated handling of node references
to the device properties framework (Sakari Ailus).
- Switch over the ACPI part of the device properties framework
to the new UUID API (Andy Shevchenko).

Pull device properties framework updates from Rafael Wysocki:
"These introduce fwnode operations for all of the separate types of
'firmware nodes' that can be handled by the device properties
framework, make the framework use const fwnode arguments all over, add
a helper for the consolidated handling of node references and switch
over the framework to the new UUID API.
Specifics:
- Introduce fwnode operations for all of the separate types of
'firmware nodes' that can be handled by the device properties
framework and drop the type field from struct fwnode_handle (Sakari
Ailus, Arnd Bergmann).
- Make the device properties framework use const fwnode arguments
