202 bool "Workarounds for PPC601 bugs"
203 depends on 6xx && (PPC_PREP || PPC_PMAC)
205 Some versions of the PPC601 (the first PowerPC chip) have bugs which
206 mean that extra synchronization instructions are required near
207 certain instructions, typically those that make major changes to the
208 CPU state. These extra instructions reduce performance slightly.
209 If you say N here, these extra instructions will not be included,
210 resulting in a kernel which will run faster but may not run at all
211 on some systems with the PPC601 chip.
213 If in doubt, say Y here.
216 bool "On-chip CPU temperature sensor support"
219 G3 and G4 processors have an on-chip temperature sensor called the
220 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
221 temperature within 2-4 degrees Celsius. This option shows the current
222 on-die temperature in /proc/cpuinfo if the cpu supports it.
224 Unfortunately, on some chip revisions, this sensor is very inaccurate
225 and in many cases, does not work at all, so don't assume the cpu
226 temp is actually what /proc/cpuinfo says it is.
229 bool "Interrupt driven TAU driver (DANGEROUS)"
232 The TAU supports an interrupt driven mode which causes an interrupt
233 whenever the temperature goes out of range. This is the fastest way
234 to get notified the temp has exceeded a range. With this option off,
235 a timer is used to re-check the temperature periodically.
237 However, on some cpus it appears that the TAU interrupt hardware
238 is buggy and can cause a situation which would lead unexplained hard
241 Unless you are extending the TAU driver, or enjoy kernel/hardware
242 debugging, leave this option off.
245 bool "Average high and low temp"
248 The TAU hardware can compare the temperature to an upper and lower
249 bound. The default behavior is to show both the upper and lower
250 bound in /proc/cpuinfo. If the range is large, the temperature is
251 either changing a lot, or the TAU hardware is broken (likely on some
252 G4's). If the range is small (around 4 degrees), the temperature is
253 relatively stable. If you say Y here, a single temperature value,
254 halfway between the upper and lower bounds, will be reported in
257 If in doubt, say N here.
262 The QUICC Engine (QE) is a new generation of communications
263 coprocessors on Freescale embedded CPUs (akin to CPM in older chips).
264 Selecting this option means that you wish to build a kernel
265 for a machine with a QE coprocessor.
271 The CPM2 (Communications Processor Module) is a coprocessor on
272 embedded CPUs made by Freescale. Selecting this option means that
273 you wish to build a kernel for a machine with a CPM2 coprocessor
274 on it (826x, 827x, 8560).
277 tristate "Axon DDR2 memory device driver"
278 depends on PPC_IBM_CELL_BLADE
281 It registers one block device per Axon's DDR2 memory bank found
282 on a system. Block devices are called axonram?, their major and
283 minor numbers are available in /proc/devices, /proc/partitions or
284 in /sys/block/axonram?/dev.
