treewide: remove redundant IS_ERR() before error code check
'PTR_ERR(p) == -E*' is a stronger condition than IS_ERR(p). Hence, IS_ERR(p) is unneeded.

ACPI: thermal: switch to use <linux/units.h> helpers
This switches the ACPI thermal zone driver to use celsius_to_deci_kelvin(), deci_kelvin_to_celsius(), and deci_kelvin_to_millicelsius_with_offset() in <linux/units.h> instead of helpers in <linux/thermal.h>. This is preparation for centralizing the kelvin to/from Celsius conversion helpers in <linux/units.h>.

ACPI/IORT: Fix 'Number of IDs' handling in iort_id_map()
The IORT specification [0] (Section 3, table 4, page 9) defines the 'Number of IDs' as 'The number of IDs in the range minus one'. However, the IORT ID mapping function iort_id_map() treats the 'Number of IDs' field as if it were the full IDs mapping count, with the following check in place to detect out of boundary input IDs: InputID >= Input base + Number of IDs This check is flawed in that it considers the 'Number of IDs' field as the full number of IDs mapping and disregards the 'minus one' from the IDs count. The correct check in iort_id_map() should be implemented as: InputID > Input base + Number of IDs this implements the specification correctly but unfortunately it breaks existing firmwares that erroneously set the 'Number of IDs' as the full IDs mapping count rather than IDs mapping count minus one. e.g. PCI hostbridge mapping entry 1: Input base: 0x1000 ID Count: 0x100 Output base: 0x1000 Output reference: 0xC4 //ITS reference PCI hostbridge mapping entry 2: Input base: 0x1100 ID Count: 0x100 Output base: 0x2000 Output reference: 0xD4 //ITS reference Two mapping entries which the second entry's Input base = the first entry's Input base + ID count, so for InputID 0x1100 and with the correct InputID check in place in iort_id_map() the kernel would map the InputID to ITS 0xC4 not 0xD4 as it would be expected. Therefore, to keep supporting existing flawed firmwares, introduce a workaround that instructs the kernel to use the old InputID range check logic in iort_id_map(), so that we can support both firmwares written with the flawed 'Number of IDs' logic and the correct one as defined in the specifications.

apei/ghes: Do not delay GHES polling
Currently, the ghes_poll_func() timer callback is registered with the TIMER_DEFERRABLE flag. Thus, it is run when the CPU eventually wakes up together with a subsequent non-deferrable timer and not at the precisely configured polling interval. For polling mode, the polling interval configured by firmware should not be exceeded according to the ACPI spec 6.3, Table 18-394. The definition of the polling interval is: "Indicates the poll interval in milliseconds OSPM should use to periodically check the error source for the presence of an error condition." If this interval is extended due to the timer callback deferring, error records can get lost. Which we are observing on our ThunderX2 platforms. Therefore, remove the TIMER_DEFERRABLE flag so that the timer callback executes at the precise interval.

iommu/arm-smmu: Support SMMU module probing from the IORT
Add support for SMMU drivers built as modules to the ACPI/IORT device probing path, by deferring the probe of the master if the SMMU driver is known to exist but has not been loaded yet. Given that the IORT code registers a platform device for each SMMU that it discovers, we can easily trigger the udev based autoloading of the SMMU drivers by making the platform device identifier part of the module alias.

ACPICA: Dispatcher: always generate buffer objects for ASL create_field() operator
ACPICA commit 79a466b64e6af36cc83102f05915e56cb7dd89ab
According to table 19-419 of the ACPI 6.3 specification, buffer_fields
created using the ASL create_field() Operator have been treated as
integers if the buffer_field is small enough to fit inside of an ASL
integer (32-bits or 64-bits depending on the definition block
revision). If they are larger, buffer fields are treated as ASL
Buffer objects. However, this is not true for other AML interpreter
implementations.
It has been discovered that other AML interpreters always treat
buffer fields created by create_field() as a buffer regardless of the
length of the buffer field.
More specifically, the Microsoft AML interpreter always treats buffer
fields created by the create_field() operator as buffer. ACPICA
currently does this only when the field size is larger than the
maximum integer width. This causes problems with AML code shipped in
Microsoft Surface devices.
More details:
The control methods in these devices determine the success of an ASL
control method execution by examining the type resulting from storing
a buffer field created by a create_field() operator. On success, a
Buffer object is expected, on failure an Integer containing an error
code. This buffer object is created with a dynamic size via the
create_field() operator. Due to the difference in behavior, Buffer
values of small size are however converted to Integers and thus
interpreted by the control method as having failed, whereas in
reality it succeeded. Below is an example of a control method called
TEST that illustrates this behavior.
Method (CBUF) // Create a Buffer field
{
/*
* Depending on the value of RAND, ACPICA interpreter will treat
* BF00 as an integer or buffer.
*/
create_field (BUFF, 0, RAND, BF00)
return (BF00)
}
Method (TEST)
{
/*
* Storing the value returned by CBUF to local0 will result in
* implicit type conversion outlined in the ACPI specification.
*
* ACPICA will treat local0 like an ASL integer if RAND is less
* than or equal to 64 or 32 (depending on the definition_block
* revision). If RAND is greater, it will be treated like an ASL
* buffer. Other implementations treat local0 like an ASL buffer
* regardless of the value of RAND.
*/
local0 = CBUF()
/*
* object_type of 0x03 represents an ASL Buffer
*/
if (object_type (Local0) != 0x03)
{
// Error on ACPICA if RAND is small enough
}
else
{
/*
* Success on APICA if RAND is large enough
* Other implementations always take this path because local0
* is always treated as a buffer.
*/
}
}
This change prohibits the previously mentioned integer conversion to
match other AML interpreter implementations (Microsoft) that do not
conform to the ACPI specification.

ACPICA: Disassembler: create buffer fields in ACPI_PARSE_LOAD_PASS1
ACPICA commit 29cc8dbc5463a93625bed87d7550a8bed8913bf4 create_buffer_field is a deferred op that is typically processed in load pass 2. However, disassembly of control method contents walk the parse tree with ACPI_PARSE_LOAD_PASS1 and AML_CREATE operators are processed in a later walk. This is a problem when there is a control method that has the same name as the AML_CREATE object. In this case, any use of the name segment will be detected as a method call rather than a reference to a buffer field. If this is detected as a method call, it can result in a mal-formed parse tree if the control methods have parameters. This change in processing AML_CREATE ops earlier solves this issue by inserting the named object in the ACPI namespace so that references to this name would be detected as a name string rather than a method call.

ACPI: video: Do not export a non working backlight interface on MSI MS-7721 boards
Despite our heuristics to not wrongly export a non working ACPI backlight interface on desktop machines, we still end up exporting one on desktops using a motherboard from the MSI MS-7721 series. I've looked at improving the heuristics, but in this case a quirk seems to be the only way to solve this. While at it also add a comment to separate the video_detect_force_none entries in the video_detect_dmi_table from other type of entries, as we already do for the other entry types.

ACPI: fan: Expose fan performance state information
When _FPS indicates variable speed fan support, the thermal cooling device for fan shows max performance state count as "max_state" (greater than or equal to 1). But the thermal cooling device doesn't expose the properties of each performance state. This is not enough for smart fan control user space software, which also considers speed, power and noise level. This change exposes the properties of the fan performance states in the sysfs directory of the ACPI device representing the fan, that is /sys/bus/acpi/devices/devices/INT3404:00 or /sys/bus/platform/devices/PNP0C0B:00. For example: $ ls /sys/bus/acpi/devices/INT3404\:00 description path state0 state11 state4 state7 status hid physical_node state1 state2 state5 state8 subsystem modalias power state10 state3 state6 state9 uevent uid wakeup where each state* attribute lists the properties of a fan performance state in the following format: control_percent:trip_point:speed_rpm:noise_level_mdb:power_mw $ cat /sys/bus/acpi/devices/INT3404\:00/state10 95:0:11600:47500:4500 as documented in Documentation/admin-guide/acpi/fan_performance_states.rst While at it, return the correct error code from acpi_fan_probe() when acpi_fan_get_fps() or acpi_fan_get_fif() fails.

ACPI / LPSS: Rename pwm_backlight pwm-lookup to pwm_soc_backlight
At least Bay Trail (BYT) and Cherry Trail (CHT) devices can use 1 of 2 different PWM controllers for controlling the LCD's backlight brightness. Either the one integrated into the PMIC or the one integrated into the SoC (the 1st LPSS PWM controller). So far in the LPSS code on BYT we have skipped registering the LPSS PWM controller "pwm_backlight" lookup entry when a Crystal Cove PMIC is present, assuming that in this case the PMIC PWM controller will be used. On CHT we have been relying on only 1 of the 2 PWM controllers being enabled in the DSDT at the same time; and always registered the lookup. So far this has been working, but the correct way to determine which PWM controller needs to be used is by checking a bit in the VBT table and recently I've learned about 2 different BYT devices: Point of View MOBII TAB-P800W Acer Switch 10 SW5-012 Which use a Crystal Cove PMIC, yet the LCD is connected to the SoC/LPSS PWM controller (and the VBT correctly indicates this), so here our old heuristics fail. Since only the i915 driver has access to the VBT, this commit renames the "pwm_backlight" lookup entries for the 1st BYT/CHT LPSS PWM controller to "pwm_soc_backlight" so that the i915 driver can do a pwm_get() for the right controller depending on the VBT bit, instead of the i915 driver relying on a "pwm_backlight" lookup getting registered which magically points to the right controller.

ACPI / battery: Use design-cap for capacity calculations if full-cap is not available
The ThunderSoft TS178 tablet's _BIX implementation reports design_capacity
but not full_charge_capacity.
Before this commit this would cause us to return -ENODEV for the capacity
attribute, which userspace does not like. Specifically upower does this:
if (sysfs_file_exists (native_path, "capacity")) {
percentage = sysfs_get_double (native_path, "capacity");
Where the sysfs_get_double() helper returns 0 when we return -ENODEV,
so the battery always reads 0% if we return -ENODEV.
This commit fixes this by using the design-capacity instead of the
full-charge-capacity when the full-charge-capacity is not available.

Convert acpi_wakeup_address from a raw variable into a function so that x86 can wrap its dereference of the real mode boot header in a function instead of broadcasting it to the world via a #define. This sets the stage for a future patch to move x86's definition of the new function, acpi_get_wakeup_address(), out of asm/acpi.h and thus break acpi.h's dependency on asm/realmode.h.

Linux, like fans, require special low-level power management handling
implemented by their drivers that is not in agreement with the ACPI

For this reason, make acpi_dev_pm_attach() skip the affected devices

Merge tag 'pm-5.5-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull additional power management updates from Rafael Wysocki:
"These fix an ACPI EC driver bug exposed by the recent rework of the
suspend-to-idle code flow, reintroduce frequency constraints into
device PM QoS (in preparation for adding QoS support to devfreq), drop
a redundant field from struct cpuidle_state and clean up Kconfig in
some places.
Specifics:
- Avoid a race condition in the ACPI EC driver that may cause systems
to be unable to leave suspend-to-idle (Rafael Wysocki)
- Drop the "disabled" field, which is redundant, from struct
cpuidle_state (Rafael Wysocki)
- Reintroduce device PM QoS frequency constraints (temporarily
introduced and than dropped during the 5.4 cycle) in preparation
for adding QoS support to devfreq (Leonard Crestez)
- Clean up indentation (in multiple places) and the cpuidle drivers
help text in Kconfig (Krzysztof Kozlowski, Randy Dunlap)"

ACPI: PM: s2idle: Rework ACPI events synchronization
Note that the EC GPE processing need not be synchronized in acpi_s2idle_wake() after invoking acpi_ec_dispatch_gpe(), because that function checks the GPE status and dispatches its handler if need be and the SCI action handler is not going to run anyway at that point. Moreover, it is better to drain all of the pending ACPI events before restoring the working-state configuration of GPEs in acpi_s2idle_restore(), because those events are likely to be related to system wakeup, in which case they will not be relevant going forward. Rework the code to take these observations into account. Tested-by: Kenneth R. Crudup <kenny@panix.com> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com> |
