ACPI / x86: Add support for LPS0 callback handler
Currenty the latest thing run during a suspend to idle attempt is the LPS0 `prepare_late` callback and the earliest thing is the `resume_early` callback. There is a desire for the `amd-pmc` driver to suspend later in the suspend process (ideally the very last thing), so create a callback that it or any other driver can hook into to do this.

ACPI: bus: Avoid using CPPC if not supported by firmware
If the platform firmware indicates that it does not support CPPC by clearing the OSC_SB_CPC_SUPPORT and OSC_SB_CPCV2_SUPPORT bits in the platform _OSC capabilities mask, avoid attempting to evaluate _CPC which may fail in that case. Because the OSC_SB_CPC_SUPPORT and OSC_SB_CPCV2_SUPPORT bits are only added to the supported platform capabilities mask on x86, when X86_FEATURE_HWP is supported, allow _CPC to be evaluated regardless in the other cases.

PM: hibernate: Honour ACPI hardware signature by default for virtual guests
The ACPI specification says that OSPM should refuse to restore from hibernate if the hardware signature changes, and should boot from scratch. However, real BIOSes often vary the hardware signature in cases where we *do* want to resume from hibernate, so Linux doesn't follow the spec by default. However, in a virtual environment there's no reason for the VMM to vary the hardware signature *unless* it wants to trigger a clean reboot as defined by the ACPI spec. So enable the check by default if a hypervisor is detected. Signed-off-by: David Woodhouse <dwmw@amazon.co.uk> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com> |

ACPI: PCC: Implement OperationRegion handler for the PCC Type 3 subtype
PCC OpRegion provides a mechanism to communicate with the platform directly from the AML. PCCT provides the list of PCC channel available in the platform, a subset or all of them can be used in PCC Opregion. This patch registers the PCC OpRegion handler before ACPI tables are loaded. This relies on the special context data passed to identify and set up the PCC channel before the OpRegion handler is executed for the first time. Typical PCC Opregion declaration looks like this: OperationRegion (PFRM, PCC, 2, 0x74) Field (PFRM, ByteAcc, NoLock, Preserve) { SIGN, 32, FLGS, 32, LEN, 32, CMD, 32, DATA, 800 } It contains four named double words followed by 100 bytes of buffer names DATA. ASL can fill out the buffer something like: /* Create global or local buffer */ Name (BUFF, Buffer (0x0C){}) /* Create double word fields over the buffer */ CreateDWordField (BUFF, 0x0, WD0) CreateDWordField (BUFF, 0x04, WD1) CreateDWordField (BUFF, 0x08, WD2) /* Fill the named fields */ WD0 = 0x50434300 SIGN = BUFF WD0 = 1 FLGS = BUFF WD0 = 0x10 LEN = BUFF /* Fill the payload in the DATA buffer */ WD0 = 0 WD1 = 0x08 WD2 = 0 DATA = BUFF /* Write to CMD field to trigger handler */ WD0 = 0x4404 CMD = BUFF This buffer is received by acpi_pcc_opregion_space_handler. This handler will fetch the complete buffer via internal_pcc_buffer. The setup handler will receive the special PCC context data which will contain the PCC channel index which used to set up the channel. The buffer pointer and length is saved in region context which is then used in the handler.

PM: hibernate: Allow ACPI hardware signature to be honoured
Theoretically, when the hardware signature in FACS changes, the OS is supposed to gracefully decline to attempt to resume from S4: "If the signature has changed, OSPM will not restore the system context and can boot from scratch" In practice, Windows doesn't do this and many laptop vendors do allow the signature to change especially when docking/undocking, so it would be a bad idea to simply comply with the specification by default in the general case. However, there are use cases where we do want the compliant behaviour and we know it's safe. Specifically, when resuming virtual machines where we know the hypervisor has changed sufficiently that resume will fail. We really want to be able to *tell* the guest kernel not to try, so it boots cleanly and doesn't just crash. This patch provides a way to opt in to the spec-compliant behaviour on the command line. A follow-up patch may do this automatically for certain "known good" machines based on a DMI match, or perhaps just for all hypervisor guests since there's no good reason a hypervisor would change the hardware_signature that it exposes to guests *unless* it wants them to obey the ACPI specification.

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. +-----------------------------------+ +---------+ | +------+ +------+ +--------------------------+ | | | CPU0 | | cpu1 | | +-----------+ | | | +------+ +------+ | | | | | | +----+ L3 | | | | +------+ +------+ cluster | | tag | | | | | CPU2 | | CPU3 | | | | | | | +------+ +------+ | +-----------+ | | | | | | +-----------------------------------+ | | +-----------------------------------+ | | | +------+ +------+ +--------------------------+ | | | | | | | +-----------+ | | | +------+ +------+ | | | | | | | | L3 | | | | +------+ +------+ +----+ tag | | | | | | | | | | | | | | +------+ +------+ | +-----------+ | | | | | | +-----------------------------------+ | L3 | | data | +-----------------------------------+ | | | +------+ +------+ | +-----------+ | | | | | | | | | | | | | +------+ +------+ +----+ L3 | | | | | | tag | | | | +------+ +------+ | | | | | | | | | | | +-----------+ | | | +------+ +------+ +--------------------------+ | +-----------------------------------| | | +-----------------------------------| | | | +------+ +------+ +--------------------------+ | | | | | | | +-----------+ | | | +------+ +------+ | | | | | | +----+ L3 | | | | +------+ +------+ | | tag | | | | | | | | | | | | | | +------+ +------+ | +-----------+ | | | | | | +-----------------------------------+ | | +-----------------------------------+ | | | +------+ +------+ +--------------------------+ | | | | | | | +-----------+ | | | +------+ +------+ | | | | | | | | L3 | | | | +------+ +------+ +---+ tag | | | | | | | | | | | | | | +------+ +------+ | +-----------+ | | | | | | +-----------------------------------+ | | +-----------------------------------+ | | | +------+ +------+ +--------------------------+ | | | | | | | +-----------+ | | | +------+ +------+ | | | | | | | | L3 | | | | +------+ +------+ +--+ tag | | | | | | | | | | | | | | +------+ +------+ | +-----------+ | | | | +---------+ +-----------------------------------+ 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.

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.

Currently only search by index is supported. However, in some cases we might need to pass the quirks to the acpi_dev_gpio_irq_get(). For this, split out acpi_dev_gpio_irq_get_by() and replace acpi_dev_gpio_irq_get() by calling above with NULL for name parameter. Fixes: |
