| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | EDAC driver needs to look up attributes of NVDIMMs provided in SMBIOS. Provide a function that looks up an acpi_nfit_memory_map from a device handle (node/socket/mc/channel/dimm) and returns the SMBIOS handle. Also pass back the "flags" so we can see if the NVDIMM is OK. Acked-by: Dan Williams <dan.j.williams@intel.com> Signed-off-by: Tony Luck <tony.luck@intel.com> Cc: "Rafael J.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | ACPICA: Remove calling of _STA from acpi_get_object_info()Hans de Goede2018-03-181-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Events: Dispatch GPEs after enabling for the first timeErik Schmauss2018-03-182-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | After being enabled for the first time, the GPEs may have STS bits already set. Setting EN bits is not sufficient to trigger the GPEs again, so this patch polls GPEs after enabling them for the first time. This is a cleaner version on top of the "GPE clear" fix generated according to Mika's report and Rafael's original Linux based fix. Based on Linux commit originated from Rafael J.

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.

* | ACPICA: Integrate package handling with module-level codeSchmauss, Erik2018-02-211-2/+6

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.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

During ACPI scan, serial devices behind SPI, I2C or UART buses are not enumerated, allowing them to be enumerated by their respective parents. Rename *spi_i2c_slave* to *serial_bus_slave* as this will be used for serial devices on serial buses (SPI, I2C or UART). On Macs an empty ResourceTemplate is returned for uart slaves. Instead the device properties "baud", "parity", "dataBits", "stopBits" are provided. Add a check for "baud" in acpi_is_serial_bus_slave().
