| * acpi/nfit: queue issuing of ars when an uc error notification comes inDave Jiang2018-07-272-3/+10
| | | | | | | | | | | | | | | | | | | | | | | | When the ACPI UC error notifier gets called and ARS_REQ bit is set with the passed in flag, we can receive -EBUSY if ARS_REQ bit is already set for the nfit_spa->ars_state. When that happens, the ARS request is dropped. That can potentially cause us to miss the unreported errors that the on going ARS request does not receive. Add an ARS_REQ_REDO state that will request short ARS upon ARS completion to grab any errors we missed.

| | | | | | | | | | | | | | | | | | | | | | The _LSR method indicates locked status via error-code-3 returned in the _LSR payload. When any error is returned the payload of _LSR is truncated to a zero-length buffer.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | My fix for a recursive Kconfig dependency caused another issue where the ACPI specific options end up in the top-level menu in 'menuconfig'. This was an unintended side-effect of having a silent option between 'menuconfig ACPI' and 'if ACPI'. Moving the ARCH_SUPPORTS_ACPI symbol ahead of the ACPI menu solves that problem and restores the previous presentation.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is unnecessary and triggers a warning in the hypervisor. Often systems have more processor entries in their ACPI tables than are actually installed/active. The ACPI_STA_DEVICE_PRESENT bit cannot be reliably used, but the ACPI_MADT_ENABLED bit can. In order to not introduce new functions in the main ACPI processor driver code, simply use acpi_get_phys_id(), which does more than we need, but which checks the MADT enabled bit in the process. Any CPU for which we can't determine the APIC ID is unlikely to work properly anyway, so the extra checks done by acpi_get_phys_id() should do no harm.

However, it is reported now that the regression also affects system states other than S5 on some systems and causes them to wake up from sleep prematurely. For this reason, make the code in question clear the status of all ACPI events when entering all sleep states (in addition to S5) to avoid the premature wakeups (this may cause some wakeup events to be missed in theory, but the likelihood of that is small and the change here simply restores the previous behavior of the code).

This means that our energy_full sysfs attribute will also always be 0, which is not useful to export. Worse we calculate our reported capacity on full_charge_capacity and if it is 0 we always report 0. This causes userspace to immediately shutdown or hibernate the laptop since it assumes that the battery is critically low. This commit makes us not report energy_full[_design] or capacity on such broken devices, avoiding the immediate shutdown / hibernate from userspace.

On insertion battery_present changes from 0 to 1 after calling acpi_battery_get_status() and acpi_battery_get_info() is called because battery->update_time is 0. The old_present condition is therefore redundant.

That behavior confuses user space deamons using wakeup_count to identify the potential system wakeup source. To avoid the confusion, only trigger acpi_pm_wakeup_event() in the acpi_button_notify() path and don't do that in the acpi_lid_initialize_state() path.

However, the system I have here has this string written differently (ThinkPad vs. Thinkpad) which makes the match fail. In addition to that, after BIOS upgrade Robin now has the same string than my system has (perhaps newer BIOS has changed the string). In any case add another DMI entry to acpi_ec_no_wakeup[] table hopefully covering all the X1 Carbon 6th systems out there.

The data node references are parsed just after the device arguments before the integer arguments. If there are no strings after the device arguments, the parsing works exactly as it used to be. Referring to a data node called "node" under device DEV, with integer arguments 0, 2 would thus look like: Package() { DEV, "node", 0, 2 } Signed-off-by: Sakari Ailus <sakari.ailus@linux.intel.com> Signed-off-by: Rafael J.

This will 1) avoid an ACPI specific references to device nodes with integer arguments as well as 2) allow making references to nodes other than device nodes in ACPI. As a by-product, convert the fwnode interger arguments to u64. The arguments were 64-bit integers on ACPI but the fwnode arguments were just 32-bit.
