These extra instructions reduce performance slightly. 225 If you say N here, these extra instructions will not be included, 226 resulting in a kernel which will run faster but may not run at all 227 on some systems with the PPC601 chip. 228 229 If in doubt, say Y here. 230 231config TAU 232 bool "On-chip CPU temperature sensor support" 233 depends on 6xx 234 help 235 G3 and G4 processors have an on-chip temperature sensor called the 236 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die 237 temperature within 2-4 degrees Celsius. This option shows the current 238 on-die temperature in /proc/cpuinfo if the cpu supports it. 239 240 Unfortunately, on some chip revisions, this sensor is very inaccurate 241 and in many cases, does not work at all, so don't assume the cpu 242 temp is actually what /proc/cpuinfo says it is. 243 244config TAU_INT 245 bool "Interrupt driven TAU driver (EXPERIMENTAL)" 246 depends on TAU 247 ---help--- 248 The TAU supports an interrupt driven mode which causes an interrupt 249 whenever the temperature goes out of range. This is the fastest way 250 to get notified the temp has exceeded a range.

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 266 /proc/cpuinfo. 267 268 If in doubt, say N here. 269 270config QUICC_ENGINE 271 bool "Freescale QUICC Engine (QE) Support" 272 depends on FSL_SOC && PPC32 273 select PPC_LIB_RHEAP 274 select CRC32 275 help 276 The QUICC Engine (QE) is a new generation of communications 277 coprocessors on Freescale embedded CPUs (akin to CPM in older chips). 278 Selecting this option means that you wish to build a kernel 279 for a machine with a QE coprocessor. 280 281config QE_GPIO 282 bool "QE GPIO support" 283 depends on QUICC_ENGINE 284 select ARCH_REQUIRE_GPIOLIB 285 help 286 Say Y here if you're going to use hardware that connects to the 287 QE GPIOs. 288 289config CPM2 290 bool "Enable support for the CPM2 (Communications Processor Module)" 291 depends on (FSL_SOC_BOOKE && PPC32) || 8260 292 select CPM 293 select PPC_LIB_RHEAP 294 select PPC_PCI_CHOICE 295 select ARCH_REQUIRE_GPIOLIB 296 help 297 The CPM2 (Communications Processor Module) is a coprocessor on 298 embedded CPUs made by Freescale.
