The more common 58 types (601, 603, 604, 740, 750, 7400), the Motorola embedded 59 versions (821, 823, 850, 855, 860, 52xx, 82xx, 83xx), the IBM embedded 60 versions (403 and 405) and the high end 64 bit Power processors 61 (POWER 3, POWER4, and IBM 970 also known as G5) 62 Unless you are building a kernel for one of the embedded processor 63 systems, 64 bit IBM RS/6000 or an Apple G5, choose 6xx. 64 Note that the kernel runs in 32-bit mode even on 64-bit chips. 65 Also note that because the 52xx, 82xx, & 83xx family has a 603e core, 66 specific support for that chipset is asked later on. 67 68config 40x 69 bool "40x" 70 71config 44x 72 bool "44x" 73 74config POWER3 75 bool "POWER3" 76 77config POWER4 78 bool "POWER4 and 970 (G5)" 79 80config 8xx 81 depends on BROKEN 82 bool "8xx" 83 84config E500 85 bool "e500" 86 87endchoice 88 89config BOOKE 90 bool 91 depends on E500 92 default y 93 94config FSL_BOOKE 95 bool 96 depends on E500 97 default y 98 99config PTE_64BIT 100 bool 101 depends on 44x 102 default y 103 104config PHYS_64BIT 105 bool 106 depends on 44x 107 default y 108 109config ALTIVEC 110 bool "AltiVec Support" 111 depends on 6xx || POWER4 112 depends on !8260 && !83xx 113 ---help--- 114 This option enables kernel support for the Altivec extensions to the 115 PowerPC processor. The kernel currently supports saving and restoring 116 altivec registers, and turning on the 'altivec enable' bit so user 117 processes can execute altivec instructions. 118 119 This option is only usefully if you have a processor that supports 120 altivec (G4, otherwise known as 74xx series), but does not have 121 any affect on a non-altivec cpu (it does, however add code to the 122 kernel). 123 124 If in doubt, say Y here. 125 126config SPE 127 bool "SPE Support" 128 depends on E500 129 ---help--- 130 This option enables kernel support for the Signal Processing 131 Extensions (SPE) to the PowerPC processor. The kernel currently 132 supports saving and restoring SPE registers, and turning on the 133 'spe enable' bit so user processes can execute SPE instructions. 134 135 This option is only usefully if you have a processor that supports 136 SPE (e500, otherwise known as 85xx series), but does not have any 137 affect on a non-spe cpu (it does, however add code to the kernel). 138 139 If in doubt, say Y here. 140 141config TAU 142 bool "Thermal Management Support" 143 depends on 6xx && !8260 && !83xx 144 help 145 G3 and G4 processors have an on-chip temperature sensor called the 146 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die 147 temperature within 2-4 degrees Celsius. This option shows the current 148 on-die temperature in /proc/cpuinfo if the cpu supports it. 149 150 Unfortunately, on some chip revisions, this sensor is very inaccurate 151 and in some cases, does not work at all, so don't assume the cpu 152 temp is actually what /proc/cpuinfo says it is. 153 154config TAU_INT 155 bool "Interrupt driven TAU driver (DANGEROUS)" 156 depends on TAU 157 ---help--- 158 The TAU supports an interrupt driven mode which causes an interrupt 159 whenever the temperature goes out of range. This is the fastest way 160 to get notified the temp has exceeded a range. With this option off, 161 a timer is used to re-check the temperature periodically. 162 163 However, on some cpus it appears that the TAU interrupt hardware 164 is buggy and can cause a situation which would lead unexplained hard 165 lockups. 166 167 Unless you are extending the TAU driver, or enjoy kernel/hardware 168 debugging, leave this option off. 169 170config TAU_AVERAGE 171 bool "Average high and low temp" 172 depends on TAU 173 ---help--- 174 The TAU hardware can compare the temperature to an upper and lower 175 bound. The default behavior is to show both the upper and lower 176 bound in /proc/cpuinfo. If the range is large, the temperature is 177 either changing a lot, or the TAU hardware is broken (likely on some 178 G4's). If the range is small (around 4 degrees), the temperature is 179 relatively stable. If you say Y here, a single temperature value, 180 halfway between the upper and lower bounds, will be reported in 181 /proc/cpuinfo. 182 183 If in doubt, say N here. 184 185config MATH_EMULATION 186 bool "Math emulation" 187 depends on 4xx || 8xx || E500 188 ---help--- 189 Some PowerPC chips designed for embedded applications do not have 190 a floating-point unit and therefore do not implement the 191 floating-point instructions in the PowerPC instruction set. If you 192 say Y here, the kernel will include code to emulate a floating-point 193 unit, which will allow programs that use floating-point 194 instructions to run. 195 196 If you have an Apple machine or an IBM RS/6000 or pSeries machine, 197 or any machine with a 6xx, 7xx or 7xxx series processor, say N 198 here. Saying Y here will not hurt performance (on any machine) but 199 will increase the size of the kernel. 200 201source "drivers/cpufreq/Kconfig" 202 203config CPU_FREQ_PMAC 204 bool "Support for Apple PowerBooks" 205 depends on CPU_FREQ && ADB_PMU 206 select CPU_FREQ_TABLE 207 help 208 This adds support for frequency switching on Apple PowerBooks, 209 this currently includes some models of iBook & Titanium 210 PowerBook. 211 212config PPC601_SYNC_FIX 213 bool "Workarounds for PPC601 bugs" 214 depends on 6xx && (PPC_PREP || PPC_PMAC) 215 help 216 Some versions of the PPC601 (the first PowerPC chip) have bugs which 217 mean that extra synchronization instructions are required near 218 certain instructions, typically those that make major changes to the 219 CPU state. These extra instructions reduce performance slightly. 220 If you say N here, these extra instructions will not be included, 221 resulting in a kernel which will run faster but may not run at all 222 on some systems with the PPC601 chip. 223 224 If in doubt, say Y here. 225 226source arch/ppc/platforms/4xx/Kconfig 227source arch/ppc/platforms/85xx/Kconfig 228 229config PPC64BRIDGE 230 bool 231 depends on POWER3 || POWER4 232 default y 233 234config PPC_STD_MMU 235 bool 236 depends on 6xx || POWER3 || POWER4 237 default y 238 239config NOT_COHERENT_CACHE 240 bool 241 depends on 4xx || 8xx 242 default y 243 244endmenu 245 246menu "Platform options" 247 248choice 249 prompt "8xx Machine Type" 250 depends on 8xx 251 default RPXLITE 252 253config RPXLITE 254 bool "RPX-Lite" 255 ---help--- 256 Single-board computers based around the PowerPC MPC8xx chips and 257 intended for embedded applications.
