This option is not user-selectable but should be selected by all platforms that need it. config UDBG_RTAS_CONSOLE bool "RTAS based debug console" depends on PPC_RTAS default n config PPC_UDBG_BEAT bool "BEAT based debug console" depends on PPC_CELLEB default n config XICS depends on PPC_PSERIES bool default y config MPIC bool default n config MPIC_WEIRD bool default n config PPC_I8259 bool default n config U3_DART bool depends on PPC_MULTIPLATFORM && PPC64 default n config PPC_RTAS bool default n config RTAS_ERROR_LOGGING bool depends on PPC_RTAS default n config RTAS_PROC bool "Proc interface to RTAS" depends on PPC_RTAS default y config RTAS_FLASH tristate "Firmware flash interface" depends on PPC64 && RTAS_PROC config PPC_PMI tristate "Support for PMI" depends PPC_IBM_CELL_BLADE help PMI (Platform Management Interrupt) is a way to communicate with the BMC (Baseboard Mangement Controller). It is used in some IBM Cell blades. default m config MMIO_NVRAM bool default n config MPIC_U3_HT_IRQS bool depends on PPC_MAPLE default y 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 || PPC_ISERIES 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 PPC_MPC106 bool default n config PPC_970_NAP bool default n config PPC_INDIRECT_IO bool select GENERIC_IOMAP default n config GENERIC_IOMAP bool default n source "drivers/cpufreq/Kconfig" menu "CPU Frequency drivers" depends on CPU_FREQ config CPU_FREQ_PMAC bool "Support for Apple PowerBooks" depends on ADB_PMU && PPC32 select CPU_FREQ_TABLE help This adds support for frequency switching on Apple PowerBooks, this currently includes some models of iBook & Titanium PowerBook. config CPU_FREQ_PMAC64 bool "Support for some Apple G5s" depends on PPC_PMAC && PPC64 select CPU_FREQ_TABLE help This adds support for frequency switching on Apple iMac G5, and some of the more recent desktop G5 machines as well. config PPC_PASEMI_CPUFREQ bool "Support for PA Semi PWRficient" depends on PPC_PASEMI default y select CPU_FREQ_TABLE help This adds the support for frequency switching on PA Semi PWRficient processors. endmenu config PPC601_SYNC_FIX bool "Workarounds for PPC601 bugs" depends on 6xx && (PPC_PREP || 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 CLASSIC32 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 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 CPM2 bool default n 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 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. endmenu
