These extra instructions reduce performance slightly. 217 If you say N here, these extra instructions will not be included, 218 resulting in a kernel which will run faster but may not run at all 219 on some systems with the PPC601 chip. 220 221 If in doubt, say Y here. 222 223config TAU 224 bool "On-chip CPU temperature sensor support" 225 depends on 6xx 226 help 227 G3 and G4 processors have an on-chip temperature sensor called the 228 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die 229 temperature within 2-4 degrees Celsius. This option shows the current 230 on-die temperature in /proc/cpuinfo if the cpu supports it. 231 232 Unfortunately, on some chip revisions, this sensor is very inaccurate 233 and in many cases, does not work at all, so don't assume the cpu 234 temp is actually what /proc/cpuinfo says it is. 235 236config TAU_INT 237 bool "Interrupt driven TAU driver (DANGEROUS)" 238 depends on TAU 239 ---help--- 240 The TAU supports an interrupt driven mode which causes an interrupt 241 whenever the temperature goes out of range. This is the fastest way 242 to get notified the temp has exceeded a range. With this option off, 243 a timer is used to re-check the temperature periodically. 244 245 However, on some cpus it appears that the TAU interrupt hardware 246 is buggy and can cause a situation which would lead unexplained hard 247 lockups. 248 249 Unless you are extending the TAU driver, or enjoy kernel/hardware 250 debugging, leave this option off. 251 252config TAU_AVERAGE 253 bool "Average high and low temp" 254 depends on TAU 255 ---help--- 256 The TAU hardware can compare the temperature to an upper and lower 257 bound. The default behavior is to show both the upper and lower 258 bound in /proc/cpuinfo. If the range is large, the temperature is 259 either changing a lot, or the TAU hardware is broken (likely on some 260 G4's). If the range is small (around 4 degrees), the temperature is 261 relatively stable. If you say Y here, a single temperature value, 262 halfway between the upper and lower bounds, will be reported in 263 /proc/cpuinfo. 264 265 If in doubt, say N here. 266 267config QUICC_ENGINE 268 bool "Freescale QUICC Engine (QE) Support" 269 depends on FSL_SOC 270 select PPC_LIB_RHEAP 271 select CRC32 272 help 273 The QUICC Engine (QE) is a new generation of communications 274 coprocessors on Freescale embedded CPUs (akin to CPM in older chips). 275 Selecting this option means that you wish to build a kernel 276 for a machine with a QE coprocessor. 277 278config QE_GPIO 279 bool "QE GPIO support" 280 depends on QUICC_ENGINE 281 select GENERIC_GPIO 282 select ARCH_REQUIRE_GPIOLIB 283 help 284 Say Y here if you're going to use hardware that connects to the 285 QE GPIOs. 286 287config CPM2 288 bool "Enable support for the CPM2 (Communications Processor Module)" 289 depends on (FSL_SOC_BOOKE && PPC32) || 8260 290 select CPM 291 select PPC_LIB_RHEAP 292 select PPC_PCI_CHOICE 293 select ARCH_REQUIRE_GPIOLIB 294 select GENERIC_GPIO 295 help 296 The CPM2 (Communications Processor Module) is a coprocessor on 297 embedded CPUs made by Freescale.
