124 It is used in some IBM Cell blades.
131 config MPIC_U3_HT_IRQS
136 config MPIC_BROKEN_REGREAD
140 This option enables a MPIC driver workaround for some chips
141 that have a bug that causes some interrupt source information
142 to not read back properly. It is safe to use on other chips as
143 well, but enabling it uses about 8KB of memory to keep copies
144 of the register contents in software.

207 config PPC601_SYNC_FIX
208 bool "Workarounds for PPC601 bugs"
209 depends on 6xx && (PPC_PREP || PPC_PMAC)
211 Some versions of the PPC601 (the first PowerPC chip) have bugs which
212 mean that extra synchronization instructions are required near
213 certain instructions, typically those that make major changes to the
214 CPU state. These extra instructions reduce performance slightly.
215 If you say N here, these extra instructions will not be included,
216 resulting in a kernel which will run faster but may not run at all
217 on some systems with the PPC601 chip.
219 If in doubt, say Y here.
222 bool "On-chip CPU temperature sensor support"
225 G3 and G4 processors have an on-chip temperature sensor called the
226 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
227 temperature within 2-4 degrees Celsius. This option shows the current
228 on-die temperature in /proc/cpuinfo if the cpu supports it.
230 Unfortunately, on some chip revisions, this sensor is very inaccurate
231 and in many cases, does not work at all, so don't assume the cpu
232 temp is actually what /proc/cpuinfo says it is.
235 bool "Interrupt driven TAU driver (DANGEROUS)"
238 The TAU supports an interrupt driven mode which causes an interrupt
239 whenever the temperature goes out of range. This is the fastest way
240 to get notified the temp has exceeded a range. With this option off,
241 a timer is used to re-check the temperature periodically.
243 However, on some cpus it appears that the TAU interrupt hardware
244 is buggy and can cause a situation which would lead unexplained hard
247 Unless you are extending the TAU driver, or enjoy kernel/hardware
248 debugging, leave this option off.
251 bool "Average high and low temp"
254 The TAU hardware can compare the temperature to an upper and lower
255 bound. The default behavior is to show both the upper and lower
256 bound in /proc/cpuinfo. If the range is large, the temperature is
257 either changing a lot, or the TAU hardware is broken (likely on some
258 G4's). If the range is small (around 4 degrees), the temperature is
259 relatively stable. If you say Y here, a single temperature value,
260 halfway between the upper and lower bounds, will be reported in
263 If in doubt, say N here.
269 The QUICC Engine (QE) is a new generation of communications
270 coprocessors on Freescale embedded CPUs (akin to CPM in older chips).
271 Selecting this option means that you wish to build a kernel
272 for a machine with a QE coprocessor.
280 The CPM2 (Communications Processor Module) is a coprocessor on
281 embedded CPUs made by Freescale. Selecting this option means that
282 you wish to build a kernel for a machine with a CPM2 coprocessor
283 on it (826x, 827x, 8560).
285 config PPC_CPM_NEW_BINDING
287 depends on CPM1 || CPM2
289 Select this if your board has been converted to use the new
290 device tree bindings for CPM, and no longer needs the
291 ioport callbacks or the platform device glue code.

298 depends on PPC_IBM_CELL_BLADE
301 It registers one block device per Axon's DDR2 memory bank found
302 on a system. Block devices are called axonram?, their major and
303 minor numbers are available in /proc/devices, /proc/partitions or
