2018-04-04ACPI / scan: Rename acpi_is_serial_bus_slave() for more general useJohn Garry
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.

2018-03-21xen/acpi: upload _PSD info for non Dom0 CPUs tooJoao Martins
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.

2018-03-18ACPICA: Remove calling of _STA from acpi_get_object_info()Hans de Goede
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) [ 0.123618] ACPI Error: Method parse/execution failed \_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.

2018-02-21ACPICA: Integrate package handling with module-level codeSchmauss, Erik
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.

2018-02-21battery: Add the battery hooking APIOgnjen Galic
This is a patch that implements a generic hooking API for the generic ACPI battery driver. With this new generic API, drivers can expose platform specific 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.

2018-01-10ACPI: utils: Introduce acpi_dev_get_first_match_name()Andy Shevchenko
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.

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.

2017-11-27ACPICA: Dispatcher: Introduce timeout mechanism for infinite loop detectionLv Zheng
ACPICA commit 9605023e7e6d1f05581502766c8cf2905bcc03d9 This patch implements a new infinite loop detection mechanism to replace the old one, it uses acpi_os_get_timer() to limit loop execution into a determined time slice. This is useful in case some hardware/firmware operations really require the AML interpreter to wait while the old mechanism could expire too fast on recent machines. The new mechanism converts old acpi_gbl_max_loop_iterations to store the user configurable value for the new mechanism in order to allow users to be still able to configure this value for acpiexec via command line. This patch also removes wrong initilization code of acpi_gbl_max_loop_iterations accordingly (it should have been initialized by ACPI_INIT_GLOBAL, and the default value is also properly tuned for acpiexec).

2017-11-21ACPI / EC: Fix regression related to PM ops support in ECDT deviceLv Zheng
On platforms (ASUS X550ZE and possibly all ASUS X series) with valid ECDT EC but invalid DSDT EC, EC PM ops won't be invoked as ECDT EC is not an ACPI device. Thus the following commit actually removed post-resume acpi_ec_enable_event() invocation for such platforms, and triggered a regression on them that after being resumed, EC (actually should be ECDT) driver stops handling EC events: Commit: c2b46d679b30c5c0d7eb47a21085943242bdd8dc Subject: ACPI / EC: Add PM operations to improve event handling for resume process Notice that the root cause actually is "ECDT is not an ACPI device" rather than "the timing of acpi_ec_enable_event() invocation", this patch fixes this issue by enumerating ECDT EC as an ACPI device. Due to the existence of the noirq stage, the ability of tuning the timing of acpi_ec_enable_event() invocation is still meaningful. This patch is a little bit different from the posted fix by moving acpi_config_boot_ec() from acpi_ec_ecdt_start() to acpi_ec_add() to make sure that EC event handling won't be stopped as long as the ACPI EC driver is bound. Thus the following sequence shouldn't disable EC event handling: unbind,suspend,resume,bind.
