10 Say Y here to get to see options for device drivers for
11 various Intel x86 platforms, including vendor-specific
12 drivers. This option alone does not add any kernel code.
13
14 If you say N, all options in this submenu will be skipped
15 and disabled.

59 help
60 Some peripherals on Bay Trail and Cherry Trail platforms signal a
61 Power Management Event (PME) to the Power Management Controller (PMC)
62 to wakeup the system. When this happens software needs to explicitly
63 clear the PME bus 0 status bit in the GPE0a_STS register to avoid an
64 IRQ storm on IRQ 9.
65
66 This is modelled in ACPI through the INT0002 ACPI device, which is
67 called a "Virtual GPIO controller" in ACPI because it defines the
68 event handler to call when the PME triggers through _AEI and _L02
69 methods as would be done for a real GPIO interrupt in ACPI.

125 help
126 This driver provides support for modifying parameters on systems
127 equipped with Intel's Rapid Start Technology. When put in an ACPI
128 sleep state, these devices will wake after either a configured
129 timeout or when the system battery reaches a critical state,
130 automatically copying memory contents to disk. On resume, the
131 firmware will copy the memory contents back to RAM and resume the OS
132 as usual.

136 depends on ACPI
137 help
138 Intel Smart Connect is a technology intended to permit devices to
139 update state by resuming for a short period of time at regular
140 intervals. If a user enables this functionality under Windows and
141 then reboots into Linux, the system may remain configured to resume
142 on suspend. In the absence of any userspace to support it, the system
143 will then remain awake until something triggers another suspend.
144
145 This driver checks to determine whether the device has Intel Smart
146 Connect enabled, and if so disables it.

152 This driver reads maximum performance ratio of each CPU and set up
153 the scheduler priority metrics. In this way scheduler can prefer
154 CPU with higher performance to schedule tasks.

156 This driver is only required when the system is not using Hardware
157 P-States (HWP). In HWP mode, priority can be read from ACPI tables.
