37 bool "ePAPR para-virtualization support"
40 Enables ePAPR para-virtualization support for guests.
42 In case of doubt, say Y
46 depends on 6xx || PPC64
48 Support for running natively on the hardware, i.e. without
49 a hypervisor. This option is not user-selectable but should
50 be selected by all platforms that need it.
52 config PPC_OF_BOOT_TRAMPOLINE
53 bool "Support booting from Open Firmware or yaboot"
54 depends on 6xx || PPC64
57 Support from booting from Open Firmware or yaboot using an
58 Open Firmware client interface. This enables the kernel to
59 communicate with open firmware to retrieve system information
60 such as the device tree.
62 In case of doubt, say Y

65 bool "RTAS based debug console"
69 config PPC_SMP_MUXED_IPI
72 Select this opton if your platform supports SMP and your
73 interrupt controller provides less than 4 interrupts to each
74 cpu. This will enable the generic code to multiplex the 4
75 messages on to one ipi.
78 bool "BEAT based debug console"

151 This option enables a MPIC driver workaround for some chips
152 that have a bug that causes some interrupt source information
153 to not read back properly. It is safe to use on other chips as
154 well, but enabling it uses about 8KB of memory to keep copies
155 of the register contents in software.

235 bool "Workarounds for PPC601 bugs"
236 depends on 6xx && (PPC_PREP || PPC_PMAC)
238 Some versions of the PPC601 (the first PowerPC chip) have bugs which
239 mean that extra synchronization instructions are required near
240 certain instructions, typically those that make major changes to the
241 CPU state. These extra instructions reduce performance slightly.
242 If you say N here, these extra instructions will not be included,
243 resulting in a kernel which will run faster but may not run at all
244 on some systems with the PPC601 chip.
246 If in doubt, say Y here.
249 bool "On-chip CPU temperature sensor support"
252 G3 and G4 processors have an on-chip temperature sensor called the
253 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
254 temperature within 2-4 degrees Celsius. This option shows the current
255 on-die temperature in /proc/cpuinfo if the cpu supports it.
257 Unfortunately, on some chip revisions, this sensor is very inaccurate
258 and in many cases, does not work at all, so don't assume the cpu
259 temp is actually what /proc/cpuinfo says it is.
262 bool "Interrupt driven TAU driver (DANGEROUS)"
265 The TAU supports an interrupt driven mode which causes an interrupt
266 whenever the temperature goes out of range. This is the fastest way
267 to get notified the temp has exceeded a range. With this option off,
268 a timer is used to re-check the temperature periodically.
270 However, on some cpus it appears that the TAU interrupt hardware
271 is buggy and can cause a situation which would lead unexplained hard
274 Unless you are extending the TAU driver, or enjoy kernel/hardware
275 debugging, leave this option off.
278 bool "Average high and low temp"
281 The TAU hardware can compare the temperature to an upper and lower
282 bound. The default behavior is to show both the upper and lower
283 bound in /proc/cpuinfo. If the range is large, the temperature is
284 either changing a lot, or the TAU hardware is broken (likely on some
285 G4's). If the range is small (around 4 degrees), the temperature is
286 relatively stable. If you say Y here, a single temperature value,
287 halfway between the upper and lower bounds, will be reported in
290 If in doubt, say N here.
293 bool "Freescale QUICC Engine (QE) Support"
294 depends on FSL_SOC && PPC32
298 The QUICC Engine (QE) is a new generation of communications
299 coprocessors on Freescale embedded CPUs (akin to CPM in older chips).
300 Selecting this option means that you wish to build a kernel
301 for a machine with a QE coprocessor.

305 depends on QUICC_ENGINE

321 The CPM2 (Communications Processor Module) is a coprocessor on
322 embedded CPUs made by Freescale. Selecting this option means that
323 you wish to build a kernel for a machine with a CPM2 coprocessor
324 on it (826x, 827x, 8560).
327 tristate "Axon DDR2 memory device driver"
328 depends on PPC_IBM_CELL_BLADE && BLOCK
331 It registers one block device per Axon's DDR2 memory bank found
332 on a system. Block devices are called axonram?, their major and
333 minor numbers are available in /proc/devices, /proc/partitions or
334 in /sys/block/axonram?/dev.

364 These are usually BCSRs used to control board's switches, LEDs,
365 chip-selects, Ethernet/USB PHY's power and various other small
366 on-board peripherals.

374 Say Y here to enable soft power-off functionality on the Freescale
375 boards with the MPC8349E-mITX-compatible MCU chips. This driver will
376 also register MCU GPIOs with the generic GPIO API, so you'll able
