It is safe to use on other chips as 168 well, but enabling it uses about 8KB of memory to keep copies 169 of the register contents in software. 170 171config EEH 172 bool 173 depends on (PPC_POWERNV || PPC_PSERIES) && PCI 174 default y 175 176config PPC_MPC106 177 bool 178 default n 179 180config PPC_970_NAP 181 bool 182 default n 183 184config PPC_P7_NAP 185 bool 186 default n 187 188config PPC_INDIRECT_PIO 189 bool 190 select GENERIC_IOMAP 191 192config PPC_INDIRECT_MMIO 193 bool 194 195config PPC_IO_WORKAROUNDS 196 bool 197 198source "drivers/cpufreq/Kconfig" 199 200menu "CPUIdle driver" 201 202source "drivers/cpuidle/Kconfig" 203 204endmenu 205 206config PPC601_SYNC_FIX 207 bool "Workarounds for PPC601 bugs" 208 depends on 6xx && PPC_PMAC 209 help 210 Some versions of the PPC601 (the first PowerPC chip) have bugs which 211 mean that extra synchronization instructions are required near 212 certain instructions, typically those that make major changes to the 213 CPU state. These extra instructions reduce performance slightly. 214 If you say N here, these extra instructions will not be included, 215 resulting in a kernel which will run faster but may not run at all 216 on some systems with the PPC601 chip. 217 218 If in doubt, say Y here. 219 220config TAU 221 bool "On-chip CPU temperature sensor support" 222 depends on 6xx 223 help 224 G3 and G4 processors have an on-chip temperature sensor called the 225 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die 226 temperature within 2-4 degrees Celsius. This option shows the current 227 on-die temperature in /proc/cpuinfo if the cpu supports it. 228 229 Unfortunately, on some chip revisions, this sensor is very inaccurate 230 and in many cases, does not work at all, so don't assume the cpu 231 temp is actually what /proc/cpuinfo says it is. 232 233config TAU_INT 234 bool "Interrupt driven TAU driver (DANGEROUS)" 235 depends on TAU 236 ---help--- 237 The TAU supports an interrupt driven mode which causes an interrupt 238 whenever the temperature goes out of range. This is the fastest way 239 to get notified the temp has exceeded a range. With this option off, 240 a timer is used to re-check the temperature periodically. 241 242 However, on some cpus it appears that the TAU interrupt hardware 243 is buggy and can cause a situation which would lead unexplained hard 244 lockups. 245 246 Unless you are extending the TAU driver, or enjoy kernel/hardware 247 debugging, leave this option off. 248 249config TAU_AVERAGE 250 bool "Average high and low temp" 251 depends on TAU 252 ---help--- 253 The TAU hardware can compare the temperature to an upper and lower 254 bound. The default behavior is to show both the upper and lower 255 bound in /proc/cpuinfo. If the range is large, the temperature is 256 either changing a lot, or the TAU hardware is broken (likely on some 257 G4's). If the range is small (around 4 degrees), the temperature is 258 relatively stable. If you say Y here, a single temperature value, 259 halfway between the upper and lower bounds, will be reported in 260 /proc/cpuinfo. 261 262 If in doubt, say N here. 263 264config QE_GPIO 265 bool "QE GPIO support" 266 depends on QUICC_ENGINE 267 select GPIOLIB 268 help 269 Say Y here if you're going to use hardware that connects to the 270 QE GPIOs. 271 272config CPM2 273 bool "Enable support for the CPM2 (Communications Processor Module)" 274 depends on (FSL_SOC_BOOKE && PPC32) || 8260 275 select CPM 276 select PPC_PCI_CHOICE 277 select GPIOLIB 278 help 279 The CPM2 (Communications Processor Module) is a coprocessor on 280 embedded CPUs made by Freescale.
