ACPICA: provide abstraction for raw_spinlock_t

2018-05-10T15:18:45Z

Provide a new lock type acpi_raw_spinlock which is implemented as raw_spinlock_t on Linux. This type should be used in code which covers small areas of code and disables interrupts only for short time even on a realtime OS. There is a fallback to spinlock_t if an OS does not provide an implementation for acpi_raw_spinlock. Signed-off-by: Sebastian Andrzej Siewior Signed-off-by: Rafael J. Wysocki

ACPICA: Remove calling of _STA from acpi_get_object_info()

2018-03-18T17:52:00Z

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. Signed-off-by: Hans de Goede Signed-off-by: Erik Schmauss Signed-off-by: Rafael J. Wysocki

ACPICA: Events: Dispatch GPEs after enabling for the first time

2018-03-18T17:52:00Z

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. Wysocki, fixed by Lv Zheng. Signed-off-by: Lv Zheng Signed-off-by: Erik Schmauss Signed-off-by: Rafael J. Wysocki

ACPICA: Avoid NULL pointer arithmetic

2018-02-04T07:58:31Z

We should not assume NULL is defined as "(void *)0" because NULL is an implementation-defined macro. Especially, Clang 6 complains about it, i.e., "arithmetic on a null pointer treated as a cast from integer to pointer is a GNU extension".
