126 PMI (Platform Management Interrupt) is a way to

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

211 config PPC601_SYNC_FIX
212 bool "Workarounds for PPC601 bugs"
213 depends on 6xx && (PPC_PREP || PPC_PMAC)
215 Some versions of the PPC601 (the first PowerPC chip) have bugs which
216 mean that extra synchronization instructions are required near
217 certain instructions, typically those that make major changes to the
218 CPU state. These extra instructions reduce performance slightly.
219 If you say N here, these extra instructions will not be included,
220 resulting in a kernel which will run faster but may not run at all
221 on some systems with the PPC601 chip.
223 If in doubt, say Y here.
226 bool "On-chip CPU temperature sensor support"
229 G3 and G4 processors have an on-chip temperature sensor called the
230 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
231 temperature within 2-4 degrees Celsius. This option shows the current
232 on-die temperature in /proc/cpuinfo if the cpu supports it.
234 Unfortunately, on some chip revisions, this sensor is very inaccurate
235 and in many cases, does not work at all, so don't assume the cpu
236 temp is actually what /proc/cpuinfo says it is.
239 bool "Interrupt driven TAU driver (DANGEROUS)"
242 The TAU supports an interrupt driven mode which causes an interrupt
243 whenever the temperature goes out of range. This is the fastest way
244 to get notified the temp has exceeded a range. With this option off,
245 a timer is used to re-check the temperature periodically.
247 However, on some cpus it appears that the TAU interrupt hardware
248 is buggy and can cause a situation which would lead unexplained hard
251 Unless you are extending the TAU driver, or enjoy kernel/hardware
252 debugging, leave this option off.
255 bool "Average high and low temp"
258 The TAU hardware can compare the temperature to an upper and lower
259 bound. The default behavior is to show both the upper and lower
260 bound in /proc/cpuinfo. If the range is large, the temperature is
261 either changing a lot, or the TAU hardware is broken (likely on some
262 G4's). If the range is small (around 4 degrees), the temperature is
263 relatively stable. If you say Y here, a single temperature value,
264 halfway between the upper and lower bounds, will be reported in
267 If in doubt, say N here.
274 The QUICC Engine (QE) is a new generation of communications
275 coprocessors on Freescale embedded CPUs (akin to CPM in older chips).
276 Selecting this option means that you wish to build a kernel
277 for a machine with a QE coprocessor.
280 bool "Enable support for the CPM2 (Communications Processor Module)"
281 depends on MPC85xx || 8260
285 The CPM2 (Communications Processor Module) is a coprocessor on
286 embedded CPUs made by Freescale. Selecting this option means that
287 you wish to build a kernel for a machine with a CPM2 coprocessor
288 on it (826x, 827x, 8560).
290 config PPC_CPM_NEW_BINDING
292 depends on CPM1 || CPM2
294 Select this if your board has been converted to use the new
295 device tree bindings for CPM, and no longer needs the
296 ioport callbacks or the platform device glue code.
298 The fs_enet and cpm_uart drivers will be built as
302 tristate "Axon DDR2 memory device driver"
303 depends on PPC_IBM_CELL_BLADE
306 It registers one block device per Axon's DDR2 memory bank found
307 on a system. Block devices are called axonram?, their major and
308 minor numbers are available in /proc/devices, /proc/partitions or
309 in /sys/block/axonram?/dev.

327 platform devices for direct mapped RTC chips like the DS1742 or DS1743.
