Rafael J. Wysocki c4d19838d8 ACPI: glue: Drop cleanup callback from struct acpi_bus_type
Since PCI was the only user of the ->cleanup callback in struct
acpi_bus_type and it is not using struct acpi_bus_type any more,
drop that callback from there and update acpi_device_notify_remove()
accordingly.

Jia He 12064c1768 Revert "ACPI: Add memory semantics to acpi_os_map_memory()"
This reverts commit 437b38c511.

The memory semantics added in commit 437b38c511 causes SystemMemory
Operation region, whose address range is not described in the EFI memory
map to be mapped as NormalNC memory on arm64 platforms (through
acpi_os_map_memory() in acpi_ex_system_memory_space_handler()).

This triggers the following abort on an ARM64 Ampere eMAG machine,
because presumably the physical address range area backing the Opregion
does not support NormalNC memory attributes driven on the bus.

 Internal error: synchronous external abort: 96000410 [#1] SMP

If the Opregion address range is not present in the EFI memory map there
is no way for us to determine the memory attributes to use to map it -
defaulting to NormalNC does not work (and it is not correct on a memory
region that may have read side-effects) and therefore commit
437b38c511 should be reverted, which means reverting back to the
original behavior whereby address ranges that are mapped using
acpi_os_map_memory() default to the safe devicenGnRnE attributes on
ARM64 if the mapped address range is not defined in the EFI memory map.

Rafael J. Wysocki 0654cf05d1 ACPI: CPPC: Introduce cppc_get_nominal_perf()
On some systems the nominal_perf value retrieved via CPPC is just
a constant and fetching it doesn't require accessing any registers,
so if it is the only CPPC capability that's needed, it is wasteful
to run cppc_get_perf_caps() in order to get just that value alone,
especially when this is done for CPUs other than the one running
the code.

For this reason, introduce cppc_get_nominal_perf() allowing
nominal_perf to be obtained individually, by generalizing the
existing cppc_get_desired_perf() (and renaming it) so it can be
used to retrieve any specific CPPC capability value.

While at it, clean up the cppc_get_desired_perf() kerneldoc comment
a bit.

Lorenzo Pieralisi 437b38c511 ACPI: Add memory semantics to acpi_os_map_memory()
The memory attributes attached to memory regions depend on architecture
specific mappings.

For some memory regions, the attributes specified by firmware (eg
uncached) are not sufficient to determine how a memory region should be
mapped by an OS (for instance a region that is define as uncached in
firmware can be mapped as Normal or Device memory on arm64) and
therefore the OS must be given control on how to map the region to match
the expected mapping behaviour (eg if a mapping is requested with memory
semantics, it must allow unaligned accesses).

Rework acpi_os_map_memory() and acpi_os_ioremap() back-end to split
them into two separate code paths:

acpi_os_memmap() -> memory semantics
acpi_os_ioremap() -> MMIO semantics

The split allows the architectural implementation back-ends to detect
the default memory attributes required by the mapping in question
(ie the mapping API defines the semantics memory vs MMIO) and map the
memory accordingly.

Commit 71f6428332 ("ACPI: utils: Fix reference counting in
for_each_acpi_dev_match()") started doing "acpi_dev_put()" on a pointer
that was possibly NULL.  That fails miserably, because that helper
inline function is not set up to handle that case.

Just make acpi_dev_put() silently accept a NULL pointer, rather than
calling down to put_device() with an invalid offset off that NULL
pointer.

Currently it's possible to iterate over the dangling pointer in case the device

Instead, let's move that call inside acpi_dev_get_next_match_dev().

Erik Kaneda 9f8c7baeda ACPICA: Add PRMT module header to facilitate parsing
ACPICA commit bd46cb07e614fd85ea69e54c1f6f0ae0a5fb20ab

This structure is used in to parse PRMT in other Operating Systems
that relies on using subtable headers in order to parse ACPI tables.
Although the PRMT doesn't have "subtables" it has a list of module
information structures that act as subtables.

Daniel Scally b83e2b3067 ACPI: scan: Add function to fetch dependent of ACPI device
In some ACPI tables we encounter, devices use the _DEP method to assert
a dependence on other ACPI devices as opposed to the OpRegions that the
specification intends.

We need to be able to find those devices "from" the dependee, so add
a callback and a wrapper to walk over the acpi_dep_list and return
the dependent ACPI device.

Daniel Scally a9e10e5873 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.

    -Introduced the Reserved Memory Range(RMR) node. This is used
     to describe memory ranges that are used by endpoints and require
     a unity mapping in SMMU.
    -Introduced a flag in the RC node to express support for PRI.
    -Added a flag in the RC node to declare support for PASID forward
     information.

ACPICA commit eefb865355514048380d921de5efcf30027d6b02

IVHD type 40h uses the same field layout as type 11h, but adds support
for a new device entry type F0h (ACPI HID device entry). The new device
entry type has variable length: after fixed-length fields occupying 22
bytes, there's a field of length up to 255 (as given by the preceding
field).

Andy Shevchenko eb50aaf960 ACPI: scan: Use unique number for instance_no
The decrementation of acpi_device_bus_id->instance_no
in acpi_device_del() is incorrect, because it may cause
a duplicate instance number to be allocated next time
a device with the same acpi_device_bus_id is added.

Replace above mentioned approach by using IDA framework.

While at it, define the instance range to be [0, 4096).

Rafael J. Wysocki 52af99c3f5 ACPI: processor: Get rid of ACPICA message printing
The ACPI_DEBUG_PRINT() and ACPI_EXCEPTION() macros are used for
message printing in the ACPICA code and they should not be used
elsewhere.  Special configuration (either kernel command line or
sysfs-based) is needed to see the messages printed by them and
the format of those messages is also special and convoluted.

For this reason, replace all of the ACPI_DEBUG_PRINT() and
ACPI_EXCEPTION() instances in the ACPI processor driver with
corresponding dev_*(), acpi_handle_*() and pr_*() calls depending
on the context in which they appear.

Also drop the ACPI_PROCESSOR_COMPONENT definition that is not going
to be necessary any more.

Yian Chen 81d3c75bb3 iommu/vt-d: Add new enum value and structure for SATC
Starting from Intel Platform VT-d v3.2, BIOS may provide new remapping
structure SATC for SOC integrated devices, according to section 8.8 of
Intel VT-d architecture specification v3.2. The SATC structure reports
a list of the devices that require ATS for normal device operation. It
is a functional requirement that these devices will not work without OS
enabling ATS capability.

This patch introduces the new enum value and structure to represent the
remapping information. Kernel should parse the information from the
reporting structure and enable ATC for the devices as needed.

nor a field located in iomem. This address is used as an address offset
which eventually is given as physical address argument to ioremap or PCC
space offset to GET_PCC_VADDR. Therefore, having the __iomem annotation
does not make sense.

ACPICA commit 4b9135f5774caa796ddf826448811e8e7f08ef2f

GCC 7.1 gained -Wimplicit-fallthrough to warn on implicit fallthrough,
as well as __attribute__((__fallthrough__)) and comments to explicitly
denote that cases of fallthrough were intentional. Clang also supports
this warning and statement attribute, but not the comment form.

Robert Moore provides additional context about the lint comments being
removed. They were for "an old version of PC-Lint, which we don't use
anymore." Drop those.

This will help us enable -Wimplicit-fallthrough throughout the Linux
kernel.

Maximilian Luz 3dfaea3811 ACPICA: Fix exception code class checks
ACPICA commit 1a3a549286ea9db07d7ec700e7a70dd8bcc4354e

The macros to classify different AML exception codes are broken. For
instance,

  ACPI_ENV_EXCEPTION(Status)

will always evaluate to zero due to

  #define AE_CODE_ENVIRONMENTAL      0x0000
  #define ACPI_ENV_EXCEPTION(Status) (Status & AE_CODE_ENVIRONMENTAL)

Similarly, ACPI_AML_EXCEPTION(Status) will evaluate to a non-zero
value for error codes of type AE_CODE_PROGRAMMER, AE_CODE_ACPI_TABLES,
as well as AE_CODE_AML, and not just AE_CODE_AML as the name suggests.

This commit fixes those checks.

  updating the cpufreq core and the schedutil governor) and make
  janitorial changes in the ACPI code handling processor objects.

  Specifics:

   - Rework the passive-mode "fast switch" path in the intel_pstate
     driver to allow it receive the minimum (required) and target
     (desired) performance information from the schedutil governor so as
     to avoid running some workloads too fast (Rafael Wysocki).

   - Make the intel_pstate driver allow the policy max limit to be
     increased after the guaranteed performance value for the given CPU
     has increased (Rafael Wysocki).

   - Clean up the handling of CPU coordination types in the CPPC cpufreq
     driver and make it export frequency domains information to user
     space via sysfs (Ionela Voinescu).

   - Fix the ACPI code handling processor objects to use a correct
     coordination type when it fails to map frequency domains and drop a
     redundant CPU map initialization from it (Ionela Voinescu, Punit
     Agrawal)"
