src/sys/dev/acpi: acpi_cpu.h acpi_cpu_cstate.c
Log Message:
Add a new flag that determines whether we should check for bus master
activity (BM_STS) by reading from the PM1 register. According to the Intel
processor specification for ACPI, the FFH GAS encoding may provide a hint
that the check is not required. This may help some systems to enter C2/C3
even when e.g. usb(4) keeps the BM_STS bit always enabled.
