127 PMI (Platform Management Interrupt) is a way to

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

212 config PPC601_SYNC_FIX
213 bool "Workarounds for PPC601 bugs"
214 depends on 6xx && (PPC_PREP || PPC_PMAC)
216 Some versions of the PPC601 (the first PowerPC chip) have bugs which
217 mean that extra synchronization instructions are required near
218 certain instructions, typically those that make major changes to the
219 CPU state. These extra instructions reduce performance slightly.
220 If you say N here, these extra instructions will not be included,
221 resulting in a kernel which will run faster but may not run at all
222 on some systems with the PPC601 chip.
224 If in doubt, say Y here.
227 bool "On-chip CPU temperature sensor support"
230 G3 and G4 processors have an on-chip temperature sensor called the
231 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
232 temperature within 2-4 degrees Celsius. This option shows the current
233 on-die temperature in /proc/cpuinfo if the cpu supports it.
235 Unfortunately, on some chip revisions, this sensor is very inaccurate
236 and in many cases, does not work at all, so don't assume the cpu
237 temp is actually what /proc/cpuinfo says it is.
240 bool "Interrupt driven TAU driver (DANGEROUS)"
243 The TAU supports an interrupt driven mode which causes an interrupt
244 whenever the temperature goes out of range. This is the fastest way
245 to get notified the temp has exceeded a range. With this option off,
246 a timer is used to re-check the temperature periodically.
248 However, on some cpus it appears that the TAU interrupt hardware
249 is buggy and can cause a situation which would lead unexplained hard
252 Unless you are extending the TAU driver, or enjoy kernel/hardware
253 debugging, leave this option off.
256 bool "Average high and low temp"
259 The TAU hardware can compare the temperature to an upper and lower
260 bound. The default behavior is to show both the upper and lower
261 bound in /proc/cpuinfo. If the range is large, the temperature is
262 either changing a lot, or the TAU hardware is broken (likely on some
263 G4's). If the range is small (around 4 degrees), the temperature is
264 relatively stable. If you say Y here, a single temperature value,
265 halfway between the upper and lower bounds, will be reported in
268 If in doubt, say N here.
275 The QUICC Engine (QE) is a new generation of communications
276 coprocessors on Freescale embedded CPUs (akin to CPM in older chips).
277 Selecting this option means that you wish to build a kernel
278 for a machine with a QE coprocessor.
281 bool "Enable support for the CPM2 (Communications Processor Module)"
282 depends on MPC85xx || 8260
286 The CPM2 (Communications Processor Module) is a coprocessor on
287 embedded CPUs made by Freescale. Selecting this option means that
288 you wish to build a kernel for a machine with a CPM2 coprocessor
289 on it (826x, 827x, 8560).
291 config PPC_CPM_NEW_BINDING
293 depends on CPM1 || CPM2
295 Select this if your board has been converted to use the new
296 device tree bindings for CPM, and no longer needs the
297 ioport callbacks or the platform device glue code.

303 tristate "Axon DDR2 memory device driver"
304 depends on PPC_IBM_CELL_BLADE
307 It registers one block device per Axon's DDR2 memory bank found
308 on a system. Block devices are called axonram?, their major and
309 minor numbers are available in /proc/devices, /proc/partitions or
310 in /sys/block/axonram?/dev.
