There are few 'else' keywords which are redundant in
acpi_os_get_root_pointer(). Refactor function to get rid of them.
While here, switch to pr_err() instead of printk(KERN_ERR ...).

ACPI / platform: Add support for build-in properties
|
|
We have a couple of drivers, acpi_apd.c and acpi_lpss.c,
that need to pass extra build-in properties to the devices
they create. Previously the drivers added those properties
to the struct device which is member of the struct
acpi_device, but that does not work. Those properties need
to be assigned to the struct device of the platform device
instead in order for them to become available to the
drivers.
To fix this, this patch changes acpi_create_platform_device
function to take struct property_entry pointer as parameter.

The last step of the method termination should be the end of the method
serialization. Otherwise, the steps happening after it will face the race
issues that cannot be protected by the method serialization mechanism.
This patch fixes this issue by moving the per-method-object deletion code
prior than the end of the method serialization. Otherwise, the possible
race issues may result in AE_ALREADY_EXISTS error in a parallel
environment.

Commit 103544d86976 ("ACPI,PCI,IRQ: reduce resource requirements")
replaced the addition of PIRQ_PENALTY_PCI_USING in acpi_pci_link_allocate()
with an addition in acpi_irq_pci_sharing_penalty(), but f7eca374f000
("ACPI,PCI,IRQ: separate ISA penalty calculation") removed the use
of acpi_irq_pci_sharing_penalty() for ISA IRQs.
Therefore, PIRQ_PENALTY_PCI_USING is missing from ISA IRQs used by
interrupt links. Include that penalty by adding it in the
acpi_pci_link_allocate() path.

Ondrej reported that IRQs stopped working in v4.7 on several
platforms. A typical scenario, from Ondrej's VT82C694X/694X, is:
ACPI: Using PIC for interrupt routing
ACPI: PCI Interrupt Link [LNKA] (IRQs 1 3 4 5 6 7 10 *11 12 14 15)
ACPI: No IRQ available for PCI Interrupt Link [LNKA]
8139too 0000:00:0f.0: PCI INT A: no GSI
We're using PIC routing, so acpi_irq_balance == 0, and LNKA is already
active at IRQ 11. In that case, acpi_pci_link_allocate() only tries
to use the active IRQ (IRQ 11) which also happens to be the SCI.
We should penalize the SCI by PIRQ_PENALTY_PCI_USING, but
irq_get_trigger_type(11) returns something other than
IRQ_TYPE_LEVEL_LOW, so we penalize it by PIRQ_PENALTY_ISA_ALWAYS
instead, which makes acpi_pci_link_allocate() assume the IRQ isn't
available and give up.
Add acpi_penalize_sci_irq() so platforms can tell us the SCI IRQ,
trigger, and polarity directly and we don't have to depend on
irq_get_trigger_type().

We do not want to store the SCI penalty in the acpi_isa_irq_penalty[]
table because acpi_isa_irq_penalty[] only holds ISA IRQ penalties and
there's no guarantee that the SCI is an ISA IRQ. We add in the SCI
penalty as a special case in acpi_irq_get_penalty().
But if we called acpi_penalize_isa_irq() or acpi_irq_penalty_update()
for an SCI that happened to be an ISA IRQ, they stored the SCI
penalty (part of the acpi_irq_get_penalty() return value) in
acpi_isa_irq_penalty[]. Subsequent calls to acpi_irq_get_penalty()
returned a penalty that included *two* SCI penalties.

DT allows holes or empty phandles for references. This is used for example
in SPI subsystem where some chip selects are native and others are regular
GPIOs. In ACPI _DSD we currently do not support this but instead the
preceding reference consumes all following integer arguments.
For example we would like to support something like the below ASL fragment
for SPI:
Package () {
"cs-gpios",
Package () {
^GPIO, 19, 0, 0, // GPIO CS0
0, // Native CS
^GPIO, 20, 0, 0, // GPIO CS1
}
}
The zero in the middle means "no entry" or NULL reference. To support this
we change acpi_data_get_property_reference() to take firmware node and
num_args as argument and rename it to __acpi_node_get_property_reference().
The function returns -ENOENT if the given index resolves to "no entry"
reference and -ENODATA when there are no more entries in the property.
We then add static inline wrapper acpi_node_get_property_reference() that
passes MAX_ACPI_REFERENCE_ARGS as num_args to support the existing
behaviour which some drivers have been relying on.

Pull libnvdimm updates from Dan Williams:
"Aside from the recently added pmem sub-division support these have
been in -next for several releases with no reported issues. The sub-
division support was included in next-20161010 with no reported
issues. It passes all unit tests including new tests for all the new
functionality below.
Summary:
- PMEM sub-division support: Allow a single PMEM region to be divided
into multiple namespaces. Originally, ~2 years ago, it was thought
that partitions of a /dev/pmemX block device could handle
sub-allocations of persistent memory for different use cases. With
the decision to not support DAX mappings of raw block-devices, and
the genesis of device-dax, the need for having multiple
pmem-namespace per region has grown.
- Device-DAX unified inode: In support of dynamic-resizing of a
device-dax instance the kernel arranges for all mappings of a
device-dax node to share the same inode. This allows unmap /
truncate / invalidation events to affect all instances of the
device similar to the behavior of mmap on block devices.
- Hardware error scrubbing reworks: The original address-range-scrub
and badblocks tracking solution allowed clearing entries at the
individual namespace level, but it failed to clear the internal
list of media errors maintained at the bus level. The result was
that the next scrub or namespace disable/re-enable event would
restore the cleared badblocks, but now that is fixed. The v4.8
kernel introduced an auto-scrub-on-machine-check behavior to
repopulate the badblocks list. Now, in v4.9, the auto-scrub
behavior can be disabled and simply arrange for the error reported
in the machine-check to be added to the list.
- DIMM health-event notification support: ACPI 6.1 defines a
notification event code that can be send to ACPI NVDIMM devices. A
poll(2) capable file descriptor for these events can be obtained
from the nmemX/nfit/flags sysfs-attribute of a libnvdimm memory
device.
- Miscellaneous fixes: NVDIMM-N probe error, device-dax build error,
and a change to dedup the flush hint list to not flush the memory
controller more than necessary"

On some platforms with ACPI4 variable speed fan, reading cur_state from
cooling device returns "invalid value" error. This confuses user space
applications.
This issue occurs as the current driver doesn't take account of
"FineGrainControl" from _FIF(Fan Information). When the "FineGrainControl"
is set, _FSL(FSL Set Level) takes argument as a percent, which doesn't
have to match from any control value from _FPS(Fan Performance States).
It is also possible that the Fan is not actually running at the requested
speed returning a lower speed.
On some platforms the BIOS is setting fan speed to a level during boot,
which will not have an exact match to _FPS control values. The current
implementation will treat this level as invalid value.
The simple change is to atleast return state corresponding to a maximum
control value in the _FPS compared to the current level.

When doing an nmi backtrace of many cores, most of which are idle, the
output is a little overwhelming and very uninformative. Suppress
messages for cpus that are idling when they are interrupted and just
emit one line, "NMI backtrace for N skipped: idling at pc 0xNNN".
We do this by grouping all the cpuidle code together into a new
.cpuidle.text section, and then checking the address of the interrupted
PC to see if it lies within that section.
This commit suitably tags x86 and tile idle routines, and only adds in
the minimal framework for other architectures.

delegate to ksoftirqd .....

Pull ACPI updates from Rafael Wysocki:
"First off, the ACPICA code in the kernel is updated to upstream
revision 20160831 that brings in a few bug fixes and cleanups. In
particular, it is possible to mask GPEs now (and the sysfs interface
for GPE control is fixed on top of that), problems related to the
table loading mechanism are fixed and all code related to FADT version
2 (which has never been part of the ACPI specification) is dropped.
On the new features front, there is a new watchdog driver based on the
ACPI WDAT (ACPI Watchdog Action Table), needed on some platforms to
replace the iTCO watchdog that doesn't work there, and some UART
devices get new definitions of built-in properties (to be accessed via
the generic device properties API).
Also, included is a fix for an ACPI-related PCI resorces allocation
issue and a few problems in the EC driver and in the button and
battery drivers are fixed.
In addition to that, the ACPI CPPC library is updated to make batching
of requests sent over the PCC channel possible (which reduces the PCC
usage overhead substantially in some cases) and to support functional
fixed hardware (FFH) type of CPPC registers access (which will allow
CPPC to be used on x86 too in the future).
As usual, there are some assorted fixes and cleanups too.
Specifics:
- Update of the ACPICA code in the kernel to upstream revision
20160831 with the following major changes:
* New mechanism for GPE masking.
* Fixes for issues related to the LoadTable operator and table
loading.
* Fixes for issues related to so-called module-level code (MLC),
that is AML that doesn't belong to any methods.
* Change of the return value of the _OSI method to reflect the
Windows behavior.
* GAS (Generic Address Structure) support fix related to 32-bit
FADT addresses.
* Elimination of unnecessary FADT version 2 support.
* ACPI tools fixes and cleanups.
From Bob Moore, Lv Zheng, and Jung-uk Kim.
- ACPI sysfs interface updates to fix GPE handling (on top of the new
GPE masking mechanism in ACPICA) and issues related to table
loading (Lv Zheng).
- New watchdog driver based on the ACPI WDAT (ACPI Watchdog Action
Table), needed on some platforms to replace the iTCO watchdog that
doesn't work there and related updates of the intel_pmc_ipc,
i2c/i801 and MFD/lcp_ich drivers (Mika Westerberg).
- Driver core fix to prevent it from leaking secondary fwnode objects
during device removal (Lukas Wunner).
- New definitions of built-in properties for UART in ACPI-based x86
SoC drivers and a 8250_dw driver quirk for the APM X-Gene SoC
(Heikki Krogerus).
- New device ID for the Vulcan SPI controller and constification of
local strucures in the AMD SoC (APD) ACPI driver (Kamlakant Patel,
Julia Lawall).
- Fix for a bug causing the allocation of PCI resorces to fail if
ACPI-enumerated child platform devices are registered below the PCI
devices in question (Mika Westerberg).
- Change of the default polarity for PCI legacy IRQs to high on
systems booting wth ACPI on platforms with a GIC interrupt
controller model fixing the discrepancy between the specification
and HW behavior (Lorenzo Pieralisi).
- Fixes for the handling of system suspend/resume in the ACPI EC
driver and update of that driver to make it cope with the cases
when the EC device defined in the ECDT has to be used throughout
the entire system life cycle (Lv Zheng).
- Update of the ACPI CPPC library to allow it to batch requests sent
over the PCC channel (to reduce overhead), to support the fixed
functional hardware (FFH) CPPC registers access type, to notify the
mailbox framework about TX completions when the interrupt flag is
set for the PCC mailbox, and to support HW-Reduced Communication
Subspace type 2 (Ashwin Chaugule, Prashanth Prakash, Srinivas
Pandruvada, Hoan Tran).
- ACPI button driver fix and documentation update related to the
handling of laptop lids (Lv Zheng).
- ACPI battery driver initialization fix (Carlos Garnacho).
- ACPI GPIO enumeration documentation update (Mika Westerberg).
- Assorted updates of the core ACPI bus type code (Lukas Wunner, Lv
Zheng).
- Assorted cleanups of the ACPI table parsing code and the
x86-specific ACPI code (Al Stone).
- Fixes for assorted ACPI-related issues found in linux-next (Wei
Yongjun)"

Starting a full Address Range Scrub (ARS) on hitting a memory error
machine check exception may not always be desirable. Provide a way
through sysfs to toggle the behavior between just adding the address
(cache line) where the MCE happened to the poison list and doing a full
scrub. The former (selective insertion of the address) is done
unconditionally.

'ARM Server Base Boot Requiremets' [1] mentions SPCR (Serial Port
Console Redirection Table) [2] as a mandatory ACPI table that
specifies the configuration of serial console.
Defer initialization of DT earlycon until ACPI/DT decision is made.
Parse the ACPI SPCR table, setup earlycon if required,
enable specified console.
Thanks to Peter Hurley for explaining how this should work.

Added one additional parameter to thermal_zone_device_update() to provide
caller with an optional capability to specify reason.
Currently this event is used by user space governor to trigger different
processing based on event code. Also it saves an additional call to read
temperature when the event is received.
The following events are cuurently defined:
- Unspecified event
- New temperature sample
- Trip point violated
- Trip point changed
- thermal device up and down
- thermal device power capability changed

1. Install default region handlers (SystemMemory, SystemIo, PciConfig,
EmbeddedControl via ECDT) without evaluating _REG;
2. Load the table and execute the module level AML opcodes instantly.

ACPICA commit a78506e0ce8ab1d20db2a055d99cf9143e89eb29
LoadTable allows an alternative RootPathString than the default "\", while
the new table execution support fails to keep this logic.
This regression can be detected by ASLTS - TLT0.tst4, this patch fixes this
regression.
Linux upstream is not affected by this regression as we haven't enabled the
new table execution support there. BZ 1326, Lv Zheng.
