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 (DANGEROUS)" 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. With this option off, 251 a timer is used to re-check the temperature periodically. 252 253 However, on some cpus it appears that the TAU interrupt hardware 254 is buggy and can cause a situation which would lead unexplained hard 255 lockups. 256 257 Unless you are extending the TAU driver, or enjoy kernel/hardware 258 debugging, leave this option off. 259 260config TAU_AVERAGE 261 bool "Average high and low temp" 262 depends on TAU 263 ---help--- 264 The TAU hardware can compare the temperature to an upper and lower 265 bound. The default behavior is to show both the upper and lower 266 bound in /proc/cpuinfo. If the range is large, the temperature is 267 either changing a lot, or the TAU hardware is broken (likely on some 268 G4's). If the range is small (around 4 degrees), the temperature is 269 relatively stable. If you say Y here, a single temperature value, 270 halfway between the upper and lower bounds, will be reported in 271 /proc/cpuinfo. 272 273 If in doubt, say N here. 274 275config QUICC_ENGINE 276 bool "Freescale QUICC Engine (QE) Support" 277 depends on FSL_SOC && PPC32 278 select PPC_LIB_RHEAP 279 select CRC32 280 help 281 The QUICC Engine (QE) is a new generation of communications 282 coprocessors on Freescale embedded CPUs (akin to CPM in older chips). 283 Selecting this option means that you wish to build a kernel 284 for a machine with a QE coprocessor. 285 286config QE_GPIO 287 bool "QE GPIO support" 288 depends on QUICC_ENGINE 289 select GENERIC_GPIO 290 select ARCH_REQUIRE_GPIOLIB 291 help 292 Say Y here if you're going to use hardware that connects to the 293 QE GPIOs. 294 295config CPM2 296 bool "Enable support for the CPM2 (Communications Processor Module)" 297 depends on (FSL_SOC_BOOKE && PPC32) || 8260 298 select CPM 299 select PPC_LIB_RHEAP 300 select PPC_PCI_CHOICE 301 select ARCH_REQUIRE_GPIOLIB 302 select GENERIC_GPIO 303 help 304 The CPM2 (Communications Processor Module) is a coprocessor on 305 embedded CPUs made by Freescale.
