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" default n help Enables ePAPR para-virtualization support for guests. In case of doubt, say Y config PPC_NATIVE bool depends on 6xx || 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 6xx || 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 UDBG_RTAS_CONSOLE bool "RTAS based debug console" depends on PPC_RTAS default n config PPC_SMP_MUXED_IPI bool help Select this opton 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 default n config MPIC bool default n config MPIC_TIMER bool "MPIC Global Timer" depends on MPIC && FSL_SOC default n 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 default n 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 default n select EPAPR_PARAVIRT config MPIC_WEIRD bool default n config MPIC_MSGR bool "MPIC message register support" depends on MPIC default n help Enables support for the MPIC message registers. These registers are used for inter-processor communication. config PPC_I8259 bool default n config U3_DART bool depends on PPC64 default n config PPC_RTAS bool default n config RTAS_ERROR_LOGGING bool depends on PPC_RTAS default n config PPC_RTAS_DAEMON bool depends on PPC_RTAS default n 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 default n config MPIC_U3_HT_IRQS bool default n 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 IBMVIO depends on PPC_PSERIES bool default y config IBMEBUS depends on PPC_PSERIES bool "Support for GX bus based adapters" help Bus device driver for GX bus based adapters. config EEH bool depends on (PPC_POWERNV || PPC_PSERIES) && PCI default y config PPC_MPC106 bool default n config PPC_970_NAP bool default n config PPC_P7_NAP bool default n 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 6xx && PPC_PMAC 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 6xx 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, on some chip revisions, this sensor is very inaccurate and in many cases, does not work at all, so don't assume the cpu temp is actually what /proc/cpuinfo says it is. config TAU_INT bool "Interrupt driven TAU driver (DANGEROUS)" 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. However, on some cpus it appears that the TAU interrupt hardware is buggy and can cause a situation which would lead unexplained hard lockups. Unless you are extending the TAU driver, or enjoy kernel/hardware debugging, leave this option off. 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 QUICC_ENGINE bool "Freescale QUICC Engine (QE) Support" depends on FSL_SOC && PPC32 select PPC_LIB_RHEAP select CRC32 help The QUICC Engine (QE) is a new generation of communications coprocessors on Freescale embedded CPUs (akin to CPM in older chips). Selecting this option means that you wish to build a kernel for a machine with a QE coprocessor. config QE_GPIO bool "QE GPIO support" depends on QUICC_ENGINE select ARCH_REQUIRE_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 PPC_LIB_RHEAP select PPC_PCI_CHOICE select ARCH_REQUIRE_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 AXON_RAM tristate "Axon DDR2 memory device driver" depends on PPC_IBM_CELL_BLADE && BLOCK default m help It registers one block device per Axon's DDR2 memory bank found on a system. Block devices are called axonram?, their major and minor numbers are available in /proc/devices, /proc/partitions or in /sys/block/axonram?/dev. config FSL_ULI1575 bool default n 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 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 SIMPLE_GPIO bool "Support for simple, memory-mapped GPIO controllers" depends on PPC select ARCH_REQUIRE_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 ARCH_REQUIRE_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
