Change ACPI version from V3 to V5 to support hardware-reduced ACPI, which is a V5 feature Remove/obsolete the PM1X related stuff as they are not used for hardware-reduced ACPI Add the _S5 method in DSDT table Using hardware-reduced mode allows to use a much simpler form of ACPI that does not require supporting the legacy of previous versions of the specification such as SCI IRQ. Hardware-reduced mode is specified by setting the Hardware Reduced (HW_REDUCED_ACPI) flag in FADT table. If the HW_REDUCED_ACPI flag in the FADT table is set, OSPM will ignore fields related to the ACPI HW register interface such as the PM1x control register. Instead, sleep control/status registers can be used for system sleep state entry on hardware-reduced ACPI systems. Tracked-On: #5411 Signed-off-by: dongshen <dongsheng.x.zhang@intel.com> |
