These extra instructions reduce performance slightly. 221 If you say N here, these extra instructions will not be included, 222 resulting in a kernel which will run faster but may not run at all 223 on some systems with the PPC601 chip. 224 225 If in doubt, say Y here. 226 227config TAU 228 bool "On-chip CPU temperature sensor support" 229 depends on 6xx 230 help 231 G3 and G4 processors have an on-chip temperature sensor called the 232 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die 233 temperature within 2-4 degrees Celsius. This option shows the current 234 on-die temperature in /proc/cpuinfo if the cpu supports it. 235 236 Unfortunately, on some chip revisions, this sensor is very inaccurate 237 and in many cases, does not work at all, so don't assume the cpu 238 temp is actually what /proc/cpuinfo says it is. 239 240config TAU_INT 241 bool "Interrupt driven TAU driver (DANGEROUS)" 242 depends on TAU 243 ---help--- 244 The TAU supports an interrupt driven mode which causes an interrupt 245 whenever the temperature goes out of range. This is the fastest way 246 to get notified the temp has exceeded a range. With this option off, 247 a timer is used to re-check the temperature periodically. 248 249 However, on some cpus it appears that the TAU interrupt hardware 250 is buggy and can cause a situation which would lead unexplained hard 251 lockups. 252 253 Unless you are extending the TAU driver, or enjoy kernel/hardware 254 debugging, leave this option off. 255 256config TAU_AVERAGE 257 bool "Average high and low temp" 258 depends on TAU 259 ---help--- 260 The TAU hardware can compare the temperature to an upper and lower 261 bound. The default behavior is to show both the upper and lower 262 bound in /proc/cpuinfo. If the range is large, the temperature is 263 either changing a lot, or the TAU hardware is broken (likely on some 264 G4's). If the range is small (around 4 degrees), the temperature is 265 relatively stable. If you say Y here, a single temperature value, 266 halfway between the upper and lower bounds, will be reported in 267 /proc/cpuinfo. 268 269 If in doubt, say N here. 270 271config QUICC_ENGINE 272 bool "Freescale QUICC Engine (QE) Support" 273 depends on FSL_SOC && PPC32 274 select PPC_LIB_RHEAP 275 select CRC32 276 help 277 The QUICC Engine (QE) is a new generation of communications 278 coprocessors on Freescale embedded CPUs (akin to CPM in older chips). 279 Selecting this option means that you wish to build a kernel 280 for a machine with a QE coprocessor. 281 282config QE_GPIO 283 bool "QE GPIO support" 284 depends on QUICC_ENGINE 285 select GENERIC_GPIO 286 select ARCH_REQUIRE_GPIOLIB 287 help 288 Say Y here if you're going to use hardware that connects to the 289 QE GPIOs. 290 291config CPM2 292 bool "Enable support for the CPM2 (Communications Processor Module)" 293 depends on (FSL_SOC_BOOKE && PPC32) || 8260 294 select CPM 295 select PPC_LIB_RHEAP 296 select PPC_PCI_CHOICE 297 select ARCH_REQUIRE_GPIOLIB 298 select GENERIC_GPIO 299 help 300 The CPM2 (Communications Processor Module) is a coprocessor on 301 embedded CPUs made by Freescale.
