Subject: [PATCH 01/41] ACPI: PM: Convert debug message in
 acpi_device_get_power()

Convert the debug message printed by acpi_device_get_power() to
acpi_handle_debug(), because that function is also called when
the ACPI device object name has not been set yet and the dev_dbg()
message printed by it at that time is not useful.

All messages printed by functions in this file either contain
the "ACPI" or "acpi" string regardless of the format, or they don't
need to contain it at all.

In the former case, the "ACPI:" string added by the format is
redundant, so drop it from there.

Subject: [PATCH 06/41] PCI: ACPI: PM: Power up devices in D3cold before
 scanning them

The initial configuration of ACPI power resources on some systems
implies that some PCI devices on them are initially in D3cold.

In some cases, especially for PCIe Root Ports, this is a "logical"
D3cold, meaning that the configuration space of the device is
accessible, but some of its functionality may be missing, but it
very well may be real D3cold, in which case the device will not
be accessible at all.  However, the PCI bus type driver will need
to access its configuration space in order to enumerate it.

To prevent possible device enumeration failures that may ensue as
a result of ACPI power resources being initially in the "off"
state, power up all children of the host bridge ACPI device object
that hold valid _ADR objects (which indicates that they will be
enumerated by the PCI bus type driver) and do that to all children
of the ACPI device objects corresponding to PCI bridges (including
PCIe ports).

Subject: [PATCH 07/41] ACPI: sysfs: Fix BERT error region memory mapping

Currently the sysfs interface maps the BERT error region as "memory"
(through acpi_os_map_memory()) in order to copy the error records into
memory buffers through memory operations (eg memory_read_from_buffer()).

The OS system cannot detect whether the BERT error region is part of
system RAM or it is "device memory" (eg BMC memory) and therefore it
cannot detect which memory attributes the bus to memory support (and
corresponding kernel mapping, unless firmware provides the required
information).

The acpi_os_map_memory() arch backend implementation determines the
mapping attributes. On arm64, if the BERT error region is not present in
the EFI memory map, the error region is mapped as device-nGnRnE; this
triggers alignment faults since memcpy unaligned accesses are not
allowed in device-nGnRnE regions.

The ACPI sysfs code cannot therefore map by default the BERT error
region with memory semantics but should use a safer default.

Change the sysfs code to map the BERT error region as MMIO (through
acpi_os_map_iomem()) and use the memcpy_fromio() interface to read the
error region into the kernel buffer.

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.

 the end of Endpoint Descriptor

ACPICA commit 961221a76814ffa0ecc92219ddf857579b0f7d54

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

ACPICA commit 68c7e542075319d57129467872fcbe98906f2b2c

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

 operator

ACPICA commit 84bf573ab7222c4e1c22167b22d29c4da1552b20

DDB_HANDLE is gone, now Load() returns a pass/fail integer, as well as
storing it in an optional 2nd argument.

Subject: [PATCH 18/41] 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].

[1] https://en.wikipedia.org/wiki/Flexible_array_member
[2] https://www.kernel.org/doc/html/v5.16/process/deprecated.html#zero-length-and-one-element-arrays

 names

ACPICA commit b69cbef7a83eadb102a1ff6c6f6fc5abce34805a

`how_long` refers to different units in both functions, so make it more
clear, what unit they expect. That also makes one comment superfluous.

 violation

ACPICA commit 05ba545ce7859392250b18c10081db25c90ed8d7

Values greater than 100 microseconds violate the ACPI specification, so
warn users about it.

From ACPI Specification version 6.2 Errata A, 19.6.128 *Stall (Stall for
a Short Time)*:

> The implementation of Stall is OS-specific, but must not relinquish
> control of the processor. Because of this, delays longer than 100
> microseconds must use Sleep instead of Stall.

Subject: [PATCH 22/41] ACPICA: executer/exsystem: Warn about sleeps greater
 than 10 ms

ACPICA commit 2a0d1d475e7ea1c815bee1e0692d81db9a7c909c

Quick boottime is important, so warn about sleeps greater than 10 ms.

Distribution Linux kernels reach initrd in 350 ms, so excessive delays
should be called out. 10 ms is chosen randomly, but three of such delays
would already make up ten percent of the boottime.

Subject: [PATCH 28/41] 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: [PATCH 31/41] ACPI: PM: Always print final debug message in
 acpi_device_set_power()

acpi_device_set_power() prints debug messages regarding its outcome
(whether or not the power state has been changed and how) in all
cases except when the device whose power state is being changed to D0
is in that power state already.

Make acpi_device_set_power() print a final debug message in that case
too and while at it, fix the indentation of the "end" label in this
function.

Subject: [PATCH 32/41] ACPI, APEI, EINJ: Refuse to inject into the zero page

Some validation tests dynamically inject errors into memory used by
applications to check that the system can recover from a variety of
poison consumption sceenarios.

But sometimes the virtual address picked by these tests is mapped to
the zero page.

This causes additional unexpected machine checks as other processes that
map the zero page also consume the poison.

Disallow injection to the zero page.

Subject: [PATCH 35/41] 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: [PATCH 39/41] ACPI: PM: Block ASUS B1400CEAE from suspend to idle by
 default

ASUS B1400CEAE fails to resume from suspend to idle by default.  This was
bisected back to commit df4f9bc4fb9c ("nvme-pci: add support for ACPI
StorageD3Enable property") but this is a red herring to the problem.

Before this commit the system wasn't getting into deepest sleep state.
Presumably this commit is allowing entry into deepest sleep state as
advertised by firmware, but there are some other problems related to
the wakeup.

As it is confirmed the system works properly with S3, set the default for
this system to S3.

Subject: [PATCH 40/41] ACPI: utils: include UUID in _DSM evaluation warning
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The _DSM evaluation warning in its current form is not very helpful, as
it lacks any specific information:
  ACPI: \: failed to evaluate _DSM (0x1001)

Thus, include the UUID of the missing _DSM:
  ACPI: \: failed to evaluate _DSM bf0212f2-... (0x1001)

Subject: [PATCH 41/41] Revert "ACPICA: executer/exsystem: Warn about sleeps
 greater than 10 ms"

Commit 6eaf08770ee8 ("ACPICA: executer/exsystem: Warn about sleeps
greater than 10 ms") made acpi_ex_system_do_sleep() log a warning for
sleep times greater than 10 ms, but such sleep times are used in
power management AML because of the PCI specification requirements.

This results with logging warnings that cannot really be acted on in
any useful way which is annoying and these warnings show up in the logs
on many production systems, so revert commit 6eaf08770ee8.
