Overhead for the kernel when not running inside KVM should be minimal. In case of doubt, say Y config EPAPR_PARAVIRT bool "ePAPR para-virtualization support" help Enables ePAPR para-virtualization support for guests. In case of doubt, say Y config PPC_NATIVE bool depends on PPC_BOOK3S_32 \|\| PPC64 help Support for running natively on the hardware, i.e. without a hypervisor. This option is not user-selectable but should be selected by all platforms that need it. config PPC_OF_BOOT_TRAMPOLINE bool "Support booting from Open Firmware or yaboot" depends on PPC_BOOK3S_32 \|\| PPC64 default y help Support from booting from Open Firmware or yaboot using an Open Firmware client interface. This enables the kernel to communicate with open firmware to retrieve system information such as the device tree. In case of doubt, say Y config PPC_DT_CPU_FTRS bool "Device-tree based CPU feature discovery & setup" depends on PPC_BOOK3S_64 default y help This enables code to use a new device tree binding for describing CPU compatibility and features. Saying Y here will attempt to use the new binding if the firmware provides it. Currently only the skiboot firmware provides this binding. If you're not sure say Y. config UDBG_RTAS_CONSOLE bool "RTAS based debug console" depends on PPC_RTAS config PPC_SMP_MUXED_IPI bool help Select this option if your platform supports SMP and your interrupt controller provides less than 4 interrupts to each cpu. This will enable the generic code to multiplex the 4 messages on to one ipi. config IPIC bool config MPIC bool config MPIC_TIMER bool "MPIC Global Timer" depends on MPIC && FSL_SOC help The MPIC global timer is a hardware timer inside the Freescale PIC complying with OpenPIC standard. When the specified interval times out, the hardware timer generates an interrupt. The driver currently is only tested on fsl chip, but it can potentially support other global timers complying with the OpenPIC standard. config FSL_MPIC_TIMER_WAKEUP tristate "Freescale MPIC global timer wakeup driver" depends on FSL_SOC && MPIC_TIMER && PM help The driver provides a way to wake up the system by MPIC timer. e.g. "echo 5 > /sys/devices/system/mpic/timer_wakeup" config PPC_EPAPR_HV_PIC bool select EPAPR_PARAVIRT config MPIC_WEIRD bool config MPIC_MSGR bool "MPIC message register support" depends on MPIC help Enables support for the MPIC message registers. These registers are used for inter-processor communication. config PPC_I8259 bool config U3_DART bool depends on PPC64 config PPC_RTAS bool config RTAS_ERROR_LOGGING bool depends on PPC_RTAS config PPC_RTAS_DAEMON bool depends on PPC_RTAS config RTAS_PROC bool "Proc interface to RTAS" depends on PPC_RTAS && PROC_FS default y config RTAS_FLASH tristate "Firmware flash interface" depends on PPC64 && RTAS_PROC config MMIO_NVRAM bool config MPIC_U3_HT_IRQS bool config MPIC_BROKEN_REGREAD bool depends on MPIC help This option enables a MPIC driver workaround for some chips that have a bug that causes some interrupt source information to not read back properly. It is safe to use on other chips as well, but enabling it uses about 8KB of memory to keep copies of the register contents in software. config EEH bool depends on (PPC_POWERNV \|\| PPC_PSERIES) && PCI default y config PPC_MPC106 bool config PPC_970_NAP bool config PPC_P7_NAP bool config PPC_INDIRECT_PIO bool select GENERIC_IOMAP config PPC_INDIRECT_MMIO bool config PPC_IO_WORKAROUNDS bool source "drivers/cpufreq/Kconfig" menu "CPUIdle driver" source "drivers/cpuidle/Kconfig" endmenu config PPC601_SYNC_FIX bool "Workarounds for PPC601 bugs" depends on PPC_BOOK3S_601 && PPC_PMAC default y help Some versions of the PPC601 (the first PowerPC chip) have bugs which mean that extra synchronization instructions are required near certain instructions, typically those that make major changes to the CPU state. These extra instructions reduce performance slightly. If you say N here, these extra instructions will not be included, resulting in a kernel which will run faster but may not run at all on some systems with the PPC601 chip. If in doubt, say Y here. config TAU bool "On-chip CPU temperature sensor support" depends on PPC_BOOK3S_32 help G3 and G4 processors have an on-chip temperature sensor called the 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die temperature within 2-4 degrees Celsius. This option shows the current on-die temperature in /proc/cpuinfo if the cpu supports it. Unfortunately, this sensor is very inaccurate when uncalibrated, so don't assume the cpu temp is actually what /proc/cpuinfo says it is. config TAU_INT bool "Interrupt driven TAU driver (EXPERIMENTAL)" depends on TAU ---help--- The TAU supports an interrupt driven mode which causes an interrupt whenever the temperature goes out of range. This is the fastest way to get notified the temp has exceeded a range. With this option off, a timer is used to re-check the temperature periodically. If in doubt, say N here. config TAU_AVERAGE bool "Average high and low temp" depends on TAU ---help--- The TAU hardware can compare the temperature to an upper and lower bound. The default behavior is to show both the upper and lower bound in /proc/cpuinfo. If the range is large, the temperature is either changing a lot, or the TAU hardware is broken (likely on some G4's). If the range is small (around 4 degrees), the temperature is relatively stable. If you say Y here, a single temperature value, halfway between the upper and lower bounds, will be reported in /proc/cpuinfo. If in doubt, say N here. config QE_GPIO bool "QE GPIO support" depends on QUICC_ENGINE select GPIOLIB help Say Y here if you're going to use hardware that connects to the QE GPIOs. config CPM2 bool "Enable support for the CPM2 (Communications Processor Module)" depends on (FSL_SOC_BOOKE && PPC32) \|\| 8260 select CPM select HAVE_PCI select GPIOLIB help The CPM2 (Communications Processor Module) is a coprocessor on embedded CPUs made by Freescale. Selecting this option means that you wish to build a kernel for a machine with a CPM2 coprocessor on it (826x, 827x, 8560). config FSL_ULI1575 bool select GENERIC_ISA_DMA help Supports for the ULI1575 PCIe south bridge that exists on some Freescale reference boards. The boards all use the ULI in pretty much the same way. config CPM bool select GENERIC_ALLOCATOR config OF_RTC bool help Uses information from the OF or flattened device tree to instantiate platform devices for direct mapped RTC chips like the DS1742 or DS1743. config GEN_RTC bool "Use the platform RTC operations from user space" select RTC_CLASS select RTC_DRV_GENERIC help This option provides backwards compatibility with the old gen_rtc.ko module that was traditionally used for old PowerPC machines. Platforms should migrate to enabling the RTC_DRV_GENERIC by hand replacing their get_rtc_time/set_rtc_time callbacks with a proper RTC device driver. config SIMPLE_GPIO bool "Support for simple, memory-mapped GPIO controllers" depends on PPC select GPIOLIB help Say Y here to support simple, memory-mapped GPIO controllers. These are usually BCSRs used to control board's switches, LEDs, chip-selects, Ethernet/USB PHY's power and various other small on-board peripherals. config MCU_MPC8349EMITX bool "MPC8349E-mITX MCU driver" depends on I2C=y && PPC_83xx select GPIOLIB help Say Y here to enable soft power-off functionality on the Freescale boards with the MPC8349E-mITX-compatible MCU chips. This driver will also register MCU GPIOs with the generic GPIO API, so you'll able to use MCU pins as GPIOs. config XILINX_PCI bool "Xilinx PCI host bridge support" depends on PCI && XILINX_VIRTEX endmenu
