130 PMI (Platform Management Interrupt) is a way to

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

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

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