Brian Norris a507a3065c ACPI / processor: Finish making acpi_processor_ppc_has_changed() void
Commit bca5f557dc "ACPI / processor: Make acpi_processor_ppc_has_changed()
void" changed one of the declarations of acpi_processor_ppc_has_changed()
to return void, but the !CPU_FREQ version still returns int. Let's return
void to be consistent.

Robin Murphy a53eaef6da ACPICA: IORT: Add PMCG node supprt
PMCG nodes were added by IORT revision C, with the unfortunate oversight
that it only defined a single base address, and thus was incapable of
properly describing PMCG implementations with PMCG_CFGR.RELOC_CTRS = 1,
where the counters are in a separate page from the control registers.

Revision D corrects this by clarifying the existing field as the page 0
base address and adding a second field to describe the page 1 address
when implemented. With the spec now fit for purpose, let's support it.

Robin Murphy d87be0438e ACPICA: IORT: Update for revision D
IORT revision D contains a few additions and fixes to
currently-supported tables:

- SMMUv3 proximity domain field is enlarged to 4 bytes for consistency
  with SRAT
- Root complex nodes gain an address size limit field equivalent to that
  of named components
- Named component nodes gain a way to describe PASID (substream_ID)
  support, encoded in their flags

Additionally, we fix a couple of outstanding points in passing:
- Add the stall support flag for named components defined in revision C
- Fix SMMUv3 HTTU override mask, which should always have been 2 bits

Borislav Petkov cc7f3f1326 ghes, EDAC: Fix ghes_edac registration
Tony reported seeing

  "Internal error: Can't find EDAC structure"

when injecting correctable errors due to the fact that ghes_edac would
still load even if the whitelist won't hit. Drop the pr_err() in
ghes_edac_report_mem_error() for now due to the hacky way how ghes_edac
depends on ghes.c.

While at it, make ghes_edac_register() return an error if it doesn't hit
in the whitelist as it is the only sensible thing to do in that
situation.

Furthermore, move the call to it to happen last in ghes_probe() so that
GHES initializing properly does not depend on ghes_edac init at all
as latter is only reporting errors and not required for GHES's proper
functioning.

John Garry d87fb0917a ACPI / scan: Rename acpi_is_serial_bus_slave() for more general use
Currently the ACPI scan has special handling for serial bus slaves, in that
it makes it the responsibility of the slave device's parent to enumerate
the device.

To support other types of slave devices which require the same special
handling but where the bus is not strictly a serial bus, such as devices on
the HiSilicon LPC controller bus, rename acpi_is_serial_bus_slave() to
acpi_device_enumeration_by_parent(), so that the name can fit the wider
purpose.

Also rename the associated device flag acpi_device_flags.serial_bus_slave
to .enumeration_by_parent.

Joao Martins 4d0f1ce695 xen/acpi: upload _PSD info for non Dom0 CPUs too
All uploaded PM data from non-dom0 CPUs takes the info from vCPU 0 and
changing only the acpi_id. For processors which P-state coordination type
is HW_ALL (0xFD) it is OK to upload bogus P-state dependency information
(_PSD), because Xen will ignore any cpufreq domains created for past CPUs.

Albeit for platforms which expose coordination types as SW_ANY or SW_ALL,
this will have some unintended side effects. Effectively, it will look at
the P-state domain existence and *if it already exists* it will skip the
acpi-cpufreq initialization and thus inherit the policy from the first CPU
in the cpufreq domain. This will finally lead to the original cpu not
changing target freq to P0 other than the first in the domain. Which will
make turbo boost not getting enabled (e.g. for 'performance' governor) for
all cpus.

This patch fixes that, by also evaluating _PSD when we enumerate all ACPI
processors and thus always uploading the correct info to Xen. We export
acpi_processor_get_psd() for that this purpose, but change signature
to not assume an existent of acpi_processor given that ACPI isn't creating
an acpi_processor for non-dom0 CPUs.

Hans de Goede e7c2c3c909 ACPICA: Remove calling of _STA from acpi_get_object_info()
As the documentatuon above its declaration indicates, acpi_get_object_info()
is intended for early probe usage and as such should not call any methods
which may rely on op_regions, before this commit it was also calling _STA,
which on some systems does rely on op_regions.

Calling _STA before things are ready leads to errors such as these
(under Linux, on some hardware):

[    0.123579] ACPI Error: No handler for Region [ECRM] (00000000ba9edc4c)
               [generic_serial_bus] (20170831/evregion-166)
[    0.123601] ACPI Error: Region generic_serial_bus (ID=9) has no handler
               (20170831/exfldio-299)

               \_SB.I2C1.BAT1._STA, AE_NOT_EXIST (20170831/psparse-550)

End 2015 support for the _SUB method was removed for exactly the same
reason. Removing current_status from struct acpi_device_info only has a limited
impact. Within ACPICA it is only used by 2 debug messages, both
of which are modified to no longer print it with this commit.

Outside of ACPICA, there was one user in Linux, which has been patched to
no longer use current_status in Torvald's current master.

I've not checked if free_BSD or others are using the current_status field.

ACPICA commit a6c3c725c44dd44ad9d3f2b2a64351fdbe6e0014

For the kernel-resident ACPICA, optionally be silent about the
NOT_FOUND case. Although this is potentially a serious problem,
it can generate a lot of noise/errors on platforms whose
firmware carries around a bunch of unused Package objects.
To disable these errors, define ACPI_IGNORE_PACKAGE_RESOLUTION_ERRORS
in the OS-specific header.

Schmauss, Erik 5a8361f7ec ACPICA: Integrate package handling with module-level code
ACPICA commit 8faf6fca445eb7219963d80543fb802302a7a8c7

This change completes the integration of the recent changes to
package object handling with the module-level code support.

For acpi_exec, the -ep flag is removed.

This change allows table load to behave as if it were a method
invocation. Before this, the definition block definition below would
have loaded all named objects at the root scope. After loading, it
would execute the if statements at the root scope.

DefinitionBlock (...)
{
  Name(OBJ1, 0)

  if (1)
  {
    Device (DEV1)
    {
      Name (_HID,0x0)
    }
  }
  Scope (DEV1)
  {
    Name (OBJ2)
  }
}

The above code would load OBJ1 to the namespace, defer the execution
of the if statement and attempt to add OBJ2 within the scope of DEV1.
Since DEV1 is not in scope, this would incur an AE_NOT_FOUND error.
After this error is emitted, the if block is invoked and DEV1 and its
_HID is added to the namespace.

This commit changes the behavior to execute the if block in place
rather than deferring it until all tables are loaded. The new
behavior is as follows: insert OBJ1 in the namespace, invoke the if
statement and add DEV1 and its _HID to the namespace, add OBJ2 to the
scope of DEV1.

behaviour via sysfs attributes in /sys/class/power_supply/BATn/
in a generic way.

A perfect example of the need for this API are Lenovo ThinkPads.

Lenovo ThinkPads have a ACPI extension that allows the setting of
start and stop charge thresholds in the EC and battery firmware
via ACPI. The thinkpad_acpi module can use this API to expose
sysfs attributes that it controls inside the ACPI battery driver
sysfs tree, under /sys/class/power_supply/BATN/.

The file drivers/acpi/battery.h has been moved to
include/acpi/battery.h and the includes inside ac.c, sbs.c, and
battery.c have been adjusted to reflect that.

When drivers hooks into the API, the API calls add_battery() for
each battery in the system that passes it a acpi_battery
struct. Then, the drivers can use device_create_file() to create
new sysfs attributes with that struct and identify the batteries
for per-battery attributes.

Jung-uk Kim 761f0b8239 ACPICA: Avoid NULL pointer arithmetic
We should not assume NULL is defined as "(void *)0" because NULL is
an implementation-defined macro.  Especially, Clang 6 complains about
it, i.e., "arithmetic on a null pointer treated as a cast from integer
to pointer is a GNU extension".

Andy Shevchenko 67dcf8a3e0 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.

Erik Schmauss 87cdece169 ACPICA: DT compiler: prevent error if optional field at the end of table is not present
ACPICA commit a7f73af9003bf4e730db5a133300c01ba7992a01

The data table compiler throws under the following conditions:
 1.) there is a table with a last field that is optional
 2.) if the optional field is not present
 3.) the optional field is the last line of the data table

A change was made to dt_compile_table to return an AE_EOF under
these conditions.  This AE_EOF means that we are at the end of the
file.  The caller to dt_compile_table() is responsible for handling
this case. For DBG2 table, we will complete the compilation of this
subtable.  For other tables, this could be different.
