LinuxRKernelConfiguration中文手册(2.6.26.4)刘少侠中国·October12,20082i前言这是关于Linux内核配置菜单选项的书。Linux发展到今天，已经是版本2.6.26.4（截止2008年9月26日）。为了让广大Linux爱好者能够更加清楚的了解Linux内核的配置，笔者在业余时间里翻译了它的部分配置菜单。由于本人水平有限，且时间仓促，不足之处在所难免。欢迎广大读者批评指正，共同提高。作者：刘少侠October12,2008iiContentsI总总总览览览1II开开开始始始配配配置置置菜菜菜单单单71Generalsetup常常常规规规设设设置置置91.1Promptfordevelopmentand/orincompletecode/drivers......91.2Localversion-appendtokernelrelease................91.3Automaticallyappendversioninformationtotheversionstring...91.4Supportforpagingofanonymousmemory(swap)..........101.5SystemVIPC..............................101.6BSDProcessAccounting........................101.7Exporttask/processstatisticsthroughnetlink.............101.8Auditingsupport............................101.9Kernel.configsupport.........................111.9.1Enableaccessto.configthrough/proc/config.gz.......111.10Kernellogbuffersize...........................111.11ControlGroupsupport..........................111.12Createdeprecatedsysfsfile........................121.13Kernel→userspacerelaysupport(formerlyrelayfs)..........121.14Namespacessupport...........................121.15UTSNamespaces.............................121.15.1IPCNamespaces(IPCNS)...................121.16InitialRAMfilesystemandRAMdisksupport.............131.16.1Initramfssourcefiles.......................131.17Optimizeforsize............................131.18Configurestandardkernelfeatures(forsmallsystems)........131.19Disableheaprandomization.......................131.20ChooseSLABallocator..........................141.20.1SLAB...............................141.20.2SLUB...............................14iiiivCONTENTS1.21Profilingsupport.............................141.22Activatemarkers.............................141.23OProfilesystemprofiling.........................141.24Kprobes..................................152Loadablemodulesupport可可可加加加载载载模模模块块块支支支持持持172.1Enableloadablemodulesupport....................172.2Moduleunloading............................172.2.1Forcedmoduleunloading....................172.3Moduleversioningsupport.......................182.4Sourcechecksumforallmodules....................182.5Automatickernelmoduleloading...................183Enabletheblocklayer允允允许许许块块块设设设备备备193.1SupportforLargeBlockDevices....................193.2Supportfortracingblockioactions..................193.3SupportforLargeSingleFiles.....................203.4I/OSchedulers..............................204Processortypeandfeatures处处处理理理器器器类类类型型型及及及特特特性性性214.1TicklessSystem..............................214.2HighResolutionTimerSupport.....................214.3Symmetricmulti-processingsupport(SMP)..............214.4SubarchitectureType..........................224.5Single-depthWCHANoutput......................224.6Paravirtualizedguestsupport......................224.7Processorfamily.............................234.8Genericx86support...........................244.9HPETTimerSupport..........................244.10PreemptibleModel...........................244.10.1NoForcedPreemption(Server)................244.10.2VoluntaryKernelPreemption(Desktop)...........254.10.3PreemptibleKernel(Low-LatencyDesktop).........254.11LocalAPICsupportonuniprocessors..................254.12MachineCheckException.......................254.12.1Checkfornon-fatalerrorsonAMDAthlon/Duron/IntelPen-tium4...............................264.12.2checkforP4thermalthrottlinginterrupt............264.13ToshibaLaptopsupport........................26CONTENTSv4.14Delllaptopsupport...........................264.15EnableX86boardspecificfixupsforreboot..............264.16/dev/cpu/microcode-IntelIA32CPUmicrocodesupport......274.17/dev/cpu/*/msr-Model-specificregistersupport..........274.18/dev/cpu/*/cpuid-CPUinformationsupport............274.19HighMemorySupport.........................274.20PAESupport..............................284.21Mathemulation.............................284.22MTRR(MemoryTypeRangeRegister)support...........284.22.1x86PATsupport........................294.23EFIruntimeservicesupport......................294.24Enableseccomptosafelycomputeuntrustedbytecode(SECCOMP)294.25Timerfrequency.............................294.25.1100HZ(HZ100)........................304.25.2250HZ(HZ250)........................304.25.31000HZ(HZ1000).......................304.26kexecsystemcall............................304.27Alignmentvaluetowhichkernelshouldbealigned..........304.28CompatVDSOsupport(COMPATVDSO)..............315Powermanagementoptions电电电源源源管管管理理理选选选项项项335.1PowerManagementsupport.......................335.1.1PowerManagementDebugSupport..............335.2SuspendtoRAMandstandby......................335.3Hibernation................................335.4ACPISupport..............................345.4.1Deprecated/proc/acpifiles...................345.4.2Deprecatedpower/proc/acpidirectories............355.4.3Futurepower/sysinterface...................355.4.4Deprecated/proc/acpi/eventsupport..............355.4.5ACAdapter...........................355.4.6Battery..............................365.4.7
