Subject: ACPICA: Use uintptr_t and offsetof() in Linux kernel builds

To avoid "performing pointer subtraction with a null pointer has
undefined behavior" compiler warnings, use uintptr_t and offsetof()
that are always available during Linux kernel builds to define
acpi_uintptr_t and the ACPI_TO_INTEGER() and ACPI_OFFSET() macros.

Based on earlier proposal from Arnd Bergmann.

Subject: ACPI: bus: Introduce acpi_bus_for_each_dev()

In order to avoid exposing acpi_bus_type to modules, introduce an
acpi_bus_for_each_dev() helper for iterating over all ACPI device
objects and make typec_link_ports() use it instead of the raw
bus_for_each_dev() along with acpi_bus_type.

Having done that, drop the acpi_bus_type export.

No intentional functional impact.

Subject: ACPI: APEI: explicit init of HEST and GHES in apci_init()

From commit e147133a42cb ("ACPI / APEI: Make hest.c manage the estatus
memory pool") was merged, ghes_init() relies on acpi_hest_init() to manage
the estatus memory pool. On the other hand, ghes_init() relies on
sdei_init() to detect the SDEI version and (un)register events. The
dependencies are as follows:

    ghes_init() => acpi_hest_init() => acpi_bus_init() => acpi_init()
    ghes_init() => sdei_init()

HEST is not PCI-specific and initcall ordering is implicit and not
well-defined within a level.

Based on above, remove acpi_hest_init() from acpi_pci_root_init() and
convert ghes_init() and sdei_init() from initcalls to explicit calls in the
following order:

    acpi_hest_init()
    ghes_init()
        sdei_init()

Subject: ACPI: PM: Introduce acpi_dev_power_up_children_with_adr()

Introduce a function powering up all of the children of a given ACPI
device object that are power-manageable and hold valid _ADR ACPI
objects so as to make it possible to prepare the corresponding
"physical" devices for enumeration carried out by a bus type driver,
like PCI.

This function will be used in a subsequent change set.

Subject: ACPICA: iASL: NHLT: Treat Terminator as specific_config

ACPICA commit 23a659e190cf3ed0edd46cddf12bbbcfeaa09396

specific_config has 4 bytes of size and then an amount of bytes specified
by size. All of the terminators that I've seen had a size equal to 4, but
theoretically it can vary.

Undocumented bytes at the end of Endpoint Descriptor can be present
independently of Linux-specific structures. Their size can also vary.

Those structures aren't used by Linux drivers, and in other NHLT related
tools they are called device_info.

Subject: ACPICA: Headers: Replace zero-length array with flexible-array member
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

ACPICA commit 98835f452c698b015d4da999944405ecb90da670

There is a regular need in the kernel to provide a way to declare
having a dynamically sized set of trailing elements in a structure.
Kernel code should always use “flexible array members”[1] for these
cases. The older style of one-element or zero-length arrays should
no longer be used[2].

IORT revision is now updated to E.d (ARM DEN 0049E.d) and
contains a few additions like,
    -Added descriptor in the root complex node for specifying
     PASID width supported by the root complex.
    -Updated RMR node Flags field.
    -Introduced memory access attributes in the RMR node.

Please note that IORT Rev E.c is deprecated and not supported.

Subject: ACPI: APEI: Fix missing ERST record id

Read a record is cleared by others, but the deleted record cache entry is
still created by erst_get_record_id_next. When next enumerate the records,
get the cached deleted record, then erst_read() return -ENOENT and try to
get next record, loop back to first ID will return 0 in function
__erst_record_id_cache_add_one and then set record_id as
APEI_ERST_INVALID_RECORD_ID, finished this time read operation.
It will result in read the records just in the cache hereafter.

This patch cleared the deleted record cache, fix the issue that
"./erst-inject -p" shows record counts not equal to "./erst-inject -n".

A reproducer of the problem(retry many times):

Subject: ACPI: bus: Avoid non-ACPI device objects in walks over children

When walking the children of an ACPI device, take extra care to avoid
using to_acpi_device() on the ones that are not ACPI devices, because
that may lead to out-of-bounds access and memory corruption.

While at it, make the function passed to acpi_dev_for_each_child()
take a struct acpi_device pointer argument (instead of a struct device
one), so it is more straightforward to use.

Subject: PCI/ACPI: Prefer CXL _OSC instead of PCIe _OSC for CXL host bridges

OB In preparation for negotiating OS control of CXL _OSC features, do the
minimal enabling to use CXL _OSC to handle the base PCIe feature
negotiation. Recall that CXL _OSC is a super-set of PCIe _OSC and the
CXL 2.0 specification mandates: "If a CXL Host Bridge device exposes CXL
_OSC, CXL aware OSPM shall evaluate CXL _OSC and not evaluate PCIe
_OSC."

Rather than pass a boolean flag alongside @root to all the helper
functions that need to consider PCIe specifics, add is_pcie() and
is_cxl() helper functions to check the flavor of @root. This also
allows for dynamic fallback to PCIe _OSC in cases where an attempt to
use CXL _OXC fails. This can happen on CXL 1.1 platforms that publish
ACPI0016 devices to indicate CXL host bridges, but do not publish the
optional CXL _OSC method. CXL _OSC is mandatory for CXL 2.0 hosts.

Subject: PCI/ACPI: negotiate CXL _OSC

Add full support for negotiating _OSC as defined in the CXL 2.0 spec, as
applicable to CXL-enabled platforms. Advertise support for the CXL
features we support - 'CXL 2.0 port/device register access', 'Protocol
Error Reporting', and 'CXL Native Hot Plug'. Request control for 'CXL
Memory Error Reporting'. The requests are dependent on CONFIG_* based
prerequisites, and prior PCI enabling, similar to how the standard PCI
_OSC bits are determined.

The CXL specification does not define any additional constraints on
the hotplug flow beyond PCIe native hotplug, so a kernel that supports
native PCIe hotplug, supports CXL hotplug. For error handling protocol
and link errors just use PCIe AER. There is nascent support for
amending AER events with CXL specific status [1], but there's
otherwise no additional OS responsibility for CXL errors beyond PCIe
AER. CXL Memory Errors behave the same as typical memory errors so
CONFIG_MEMORY_FAILURE is sufficient to indicate support to platform
firmware.

+ *
+ * CONFIG_ACPI_HOTPLUG_MEMORY does depend on CONFIG_MEMORY_HOTPLUG, but

+ * ACPI memory hotplug requires the OS to acknowledge / coordinate with
+ * memory plug events via a scan handler. On the CXL side the equivalent

+ * otherwise had some coordination for the driver of a PCI device
+ * undergoing hotplug to be consulted on whether the hotplug should
+ * proceed or not.
+ *
+ * The concern is that if Linux says no to supporting CXL hotplug then
+ * the BIOS may say no to giving the OS hotplug control of any other PCIe
+ * device. So the question here is not whether hotplug is enabled, it's
+ * whether it is handled natively by the at all OS, and if
+ * CONFIG_HOTPLUG_PCI_PCIE is enabled then the answer is "yes".
+ *
+ * Otherwise, the plan for CXL coordinated remove, since the kernel does
+ * not support blocking hotplug, is to require the memory device to be
+ * disabled before hotplug is attempted. When CONFIG_MEMORY_HOTPLUG is
+ * disabled that step will fail and the remove attempt cancelled by the
+ * user. If that is not honored and the card is removed anyway then it
+ * does not matter if CONFIG_MEMORY_HOTPLUG is enabled or not, it will
+ * cause a crash and other badness.
+ *
+ * Therefore, just say yes to CXL hotplug and require removal to

From 3cc30dd00a580ca0c9c0b01639841cfd72d10129 Mon Sep 17 00:00:00 2001
From: Pierre Gondois <Pierre.Gondois@arm.com>
Date: Wed, 18 May 2022 11:09:00 +0200
Subject: cpufreq: CPPC: Enable fast_switch

The communication mean of the _CPC desired performance can be
PCC, System Memory, System IO, or Functional Fixed Hardware.

commit b7898fda5bc7 ("cpufreq: Support for fast frequency switching")
fast_switching is 'for switching CPU frequencies from interrupt
context'.
Writes to SystemMemory and SystemIo are fast and suitable this.
This is not the case for PCC and might not be the case for FFH.

Enable fast_switching for the cppc_cpufreq driver in above cases.

Add cppc_allow_fast_switch() to check the desired performance
register address space and set fast_switching accordingly.
