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. 218 219 If in doubt, say Y here. 220 221config TAU 222 bool "On-chip CPU temperature sensor support" 223 depends on CLASSIC32 224 help 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. 229 230 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. 233 234config TAU_INT 235 bool "Interrupt driven TAU driver (DANGEROUS)" 236 depends on TAU 237 ---help--- 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. 242 243 However, on some cpus it appears that the TAU interrupt hardware 244 is buggy and can cause a situation which would lead unexplained hard 245 lockups. 246 247 Unless you are extending the TAU driver, or enjoy kernel/hardware 248 debugging, leave this option off. 249 250config TAU_AVERAGE 251 bool "Average high and low temp" 252 depends on TAU 253 ---help--- 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 261 /proc/cpuinfo. 262 263 If in doubt, say N here. 264 265config QUICC_ENGINE 266 bool 267 select PPC_LIB_RHEAP 268 help 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. 273 274config CPM2 275 bool 276 default n 277 select CPM 278 select PPC_LIB_RHEAP 279 help 280 The CPM2 (Communications Processor Module) is a coprocessor on 281 embedded CPUs made by Freescale.
