The kernel currently supports saving and restoring 155 altivec registers, and turning on the 'altivec enable' bit so user 156 processes can execute altivec instructions. 157 158 This option is only usefully if you have a processor that supports 159 altivec (G4, otherwise known as 74xx series), but does not have 160 any affect on a non-altivec cpu (it does, however add code to the 161 kernel). 162 163 If in doubt, say Y here. 164 165config SPE 166 bool "SPE Support" 167 depends on E200 || E500 168 ---help--- 169 This option enables kernel support for the Signal Processing 170 Extensions (SPE) to the PowerPC processor. The kernel currently 171 supports saving and restoring SPE registers, and turning on the 172 'spe enable' bit so user processes can execute SPE instructions. 173 174 This option is only useful if you have a processor that supports 175 SPE (e500, otherwise known as 85xx series), but does not have any 176 effect on a non-spe cpu (it does, however add code to the kernel). 177 178 If in doubt, say Y here. 179 180config TAU 181 bool "Thermal Management Support" 182 depends on 6xx && !8260 && !83xx 183 help 184 G3 and G4 processors have an on-chip temperature sensor called the 185 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die 186 temperature within 2-4 degrees Celsius. This option shows the current 187 on-die temperature in /proc/cpuinfo if the cpu supports it. 188 189 Unfortunately, on some chip revisions, this sensor is very inaccurate 190 and in some cases, does not work at all, so don't assume the cpu 191 temp is actually what /proc/cpuinfo says it is. 192 193config TAU_INT 194 bool "Interrupt driven TAU driver (DANGEROUS)" 195 depends on TAU 196 ---help--- 197 The TAU supports an interrupt driven mode which causes an interrupt 198 whenever the temperature goes out of range. This is the fastest way 199 to get notified the temp has exceeded a range. With this option off, 200 a timer is used to re-check the temperature periodically. 201 202 However, on some cpus it appears that the TAU interrupt hardware 203 is buggy and can cause a situation which would lead unexplained hard 204 lockups. 205 206 Unless you are extending the TAU driver, or enjoy kernel/hardware 207 debugging, leave this option off. 208 209config TAU_AVERAGE 210 bool "Average high and low temp" 211 depends on TAU 212 ---help--- 213 The TAU hardware can compare the temperature to an upper and lower 214 bound. The default behavior is to show both the upper and lower 215 bound in /proc/cpuinfo. If the range is large, the temperature is 216 either changing a lot, or the TAU hardware is broken (likely on some 217 G4's). If the range is small (around 4 degrees), the temperature is 218 relatively stable. If you say Y here, a single temperature value, 219 halfway between the upper and lower bounds, will be reported in 220 /proc/cpuinfo. 221 222 If in doubt, say N here. 223 224config MATH_EMULATION 225 bool "Math emulation" 226 depends on 4xx || 8xx || E200 || E500 227 ---help--- 228 Some PowerPC chips designed for embedded applications do not have 229 a floating-point unit and therefore do not implement the 230 floating-point instructions in the PowerPC instruction set. If you 231 say Y here, the kernel will include code to emulate a floating-point 232 unit, which will allow programs that use floating-point 233 instructions to run. 234 235 If you have an Apple machine or an IBM RS/6000 or pSeries machine, 236 or any machine with a 6xx, 7xx or 7xxx series processor, say N 237 here. Saying Y here will not hurt performance (on any machine) but 238 will increase the size of the kernel. 239 240config KEXEC 241 bool "kexec system call (EXPERIMENTAL)" 242 depends on EXPERIMENTAL 243 help 244 kexec is a system call that implements the ability to shutdown your 245 current kernel, and to start another kernel. It is like a reboot 246 but it is independent of the system firmware. And like a reboot 247 you can start any kernel with it, not just Linux. 248 249 The name comes from the similarity to the exec system call. 250 251 It is an ongoing process to be certain the hardware in a machine 252 is properly shutdown, so do not be surprised if this code does not 253 initially work for you. It may help to enable device hotplugging 254 support. As of this writing the exact hardware interface is 255 strongly in flux, so no good recommendation can be made. 256 257 In the GameCube implementation, kexec allows you to load and 258 run DOL files, including kernel and homebrew DOLs. 259 260source "drivers/cpufreq/Kconfig" 261 262config PPC601_SYNC_FIX 263 bool "Workarounds for PPC601 bugs" 264 depends on 6xx && PPC_PREP 265 help 266 Some versions of the PPC601 (the first PowerPC chip) have bugs which 267 mean that extra synchronization instructions are required near 268 certain instructions, typically those that make major changes to the 269 CPU state. These extra instructions reduce performance slightly. 270 If you say N here, these extra instructions will not be included, 271 resulting in a kernel which will run faster but may not run at all 272 on some systems with the PPC601 chip. 273 274 If in doubt, say Y here. 275 276source arch/ppc/platforms/4xx/Kconfig 277source arch/ppc/platforms/85xx/Kconfig 278 279config PPC_STD_MMU 280 bool 281 depends on 6xx 282 default y 283 284config NOT_COHERENT_CACHE 285 bool 286 depends on 4xx || 8xx || E200 287 default y 288 289endmenu 290 291menu "Platform options" 292 293config FADS 294 bool 295 296choice 297 prompt "8xx Machine Type" 298 depends on 8xx 299 default RPXLITE 300 301config RPXLITE 302 bool "RPX-Lite" 303 ---help--- 304 Single-board computers based around the PowerPC MPC8xx chips and 305 intended for embedded applications.
