	 &nbsp; 内核参数说明<br/>下面是一个 GENERIC 内核配置文件的例子，它包括了一些需要解释的注释。 <br/>machine &nbsp; &nbsp; &nbsp; &nbsp;i386<br/>这是机器的架构， 他只能是 alpha, amd64, i386, ia64, pc98, powerpc, 或 sparc64 中的一种。<br/>cpu &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;I486_CPU<br/>cpu &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;I586_CPU<br/>cpu &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;I686_CPU<br/>上面的选项指定了您系统中所使用的 CPU 类型。 您可以使用多个 CPU 类型 (例如，您不确定是应该指定 I586_CPU 或 I686_CPU)。<br/>然而对于定制的内核， 最好能够只指定您使用的那种 CPU。如果您对于自己使用的 CPU 类型没有把握，<br/>可以通过查看 /var/run/dmesg.boot 中的启动信息来了解。<br/>ident &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;GENERIC<br/>这是内核的名字， 您应该取一个自己喜欢的名字， 这里我们取名LINUXEDU,<br/>您放在 ident 后面的字符串在启动内核时会显示出来，因<br/>此如果希望能够容易区分常用的内核和刚刚定制的内核，就应该采取不同的名字。<br/>#To statically compile in device wiring instead of /boot/device.hints<br/>#hints &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;"GENERIC.hints" &nbsp; &nbsp; &nbsp; &nbsp; # Default places to look for devices.<br/>device.hints 可以用来配置设备驱动选项。<br/>在启动的时候 loader将会检查缺省位置 /boot/devicehints。<br/>使用 hints 选项您就可以把这些 hints 静态编译进内核。 这样就没有必要在 /boot下创建devicehints。<br/>makeoptions &nbsp; &nbsp; DEBUG=-g &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;# Build kernel with gdb(1) debug symbols<br/>一般的 FreeBSD 联编过程， 在所联编的内核指定了 -g 选项时， <br/>由于此选项将传递给 gcc 表示加入调试信息， 因此会将调试符号也包含进来。 <br/>如果您使用 “旧式的” 方法来联编内核，通过使用 config的 -g 选项， <br/>也可以达到类似的目的。<br/>options &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;SCHED_4BSD &nbsp; &nbsp; &nbsp; &nbsp; # 4BSD scheduler<br/>这是 FreeBSD 传统上使用的默认系统调度器。 请保留此选项。<br/>options &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;PREEMPTION &nbsp; &nbsp; &nbsp; &nbsp; # Enable kernel thread preemption<br/>允许内核线程根据优先级的抢占调度。 这有助于改善交互性，并可以让中断线程更早地执行， 而无须等待。<br/>options &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;INET &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;# InterNETworking<br/>网络支持，即使您不打算连网，也请保留它，大部分的程序至少需要回环网络（就是和本机进行网络连接），所以强烈要求保留它。<br/>options &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;INET6 &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; # IPv6 communications protocols<br/>这将打开IPv6连接协议。<br/>options &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;FFS &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; # Berkeley Fast Filesystem<br/>这是最基本的硬盘文件系统，如果打算从本地硬盘启动，请保留它。<br/>options &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;SOFTUPDATES &nbsp; &nbsp; &nbsp; # Enable FFS Soft Updates support<br/>这个选项会启用内核中的 Soft Updates 支持， 它会显著地提高磁盘的写入速度。<br/>尽管这项功能是由内核直接提供的， 但仍然需要在每个磁盘上启用它。<br/>请检查 mount的输出，以了解您系统中的磁盘上是否已经启用了 Soft Updates。<br/>如果没有看到 soft-updates 选项， 则需要使用 tunefs(对于暨存系统) 或 <br/>newfs (对于新系统) 命令来激活它。<br/>options &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;UFS_ACL &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; # Support for access control lists<br/>这个选项将启用内核中的访问控制表的支持。 这依赖于扩展属性以及 UFS2， <br/>ACL 默认是启用的，并且如果已经在文件系统上使用了这一特性， 就不应再关掉它， 因为这会去掉文件的访问控制表，并以不可预期的方式改变受保护的文件的访问方式。<br/>options &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;UFS_DIRHASH &nbsp; &nbsp; &nbsp; # Improve performance on big directories<br/>通过使用额外的内存，这个选项可以加速在大目录上的磁盘操作。<br/>您应该在大型服务器和频繁使用的工作站上打开这个选项，而在磁盘操作不是很重要的小型系统上关闭它，比如防火墙。<br/>options &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;MD_ROOT &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; # MD is a potential root device<br/>这个选项将打开以基于内存的虚拟磁盘作为根设备的支持。<br/>options &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;NFSCLIENT &nbsp; &nbsp; &nbsp; &nbsp; # Network Filesystem Client<br/>options &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;NFSSERVER &nbsp; &nbsp; &nbsp; &nbsp; # Network Filesystem Server<br/>options &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;NFS_ROOT &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;# NFS usable as /, requires NFSCLIENT<br/>网络文件系统。 如果您不打算通过 TCP/IP 挂接 UNIX® 文件服务器的分区， 就可以注释掉它。<br/>options &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;MSDOSFS &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; # MSDOS Filesystem<br/>MS-DOS® 文件系统。 只要您不打算在启动时挂接由 DOS 格式化的硬盘分区， <br/>就可以把它注释掉。 如前面所介绍的那样， 在您第一次挂接 DOS 分区时， <br/>内核会自动加载需要的模块。 此外， emulators/mtools 软件提供了一个很方便的功能，<br/>通过它您可以直接访问 DOS 软盘而无需挂接或卸下它们 (而且也完全不需要 MSDOSFS)。<br/>options &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;CD9660 &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;# ISO 9660 Filesystem<br/>用于 CDROM 的 ISO 9660 文件系统。 如果没有 CDROM 驱动器或很少挂接光盘数据 (因为在首次使用数据 CD 时会自动加载)，<br/>就可以把它注释掉。 音乐 CD 并不需要这个选项。<br/>options &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;PROCFS &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;# Process filesystem (requires PSEUDOFS)<br/>进程文件系统。 这是一个挂接在 /proc 的一个 “假扮的” 文件系统， 其作用是允许类似<br/>ps这样的程序给出正在运行的进程的进一步信息。 多数情况下， 并不需要使用 PROCFS，<br/>因为绝大多数调试和监控工具， 已经进行了一系列修改，使之不再依赖 PROCFS：默认安装的系统中并不会挂接这一文件系统。<br/>options &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;PSEUDOFS &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;# Pseudo-filesystem framework<br/>在 6.X 内核中， 如果希望使用 PROCFS， 就必须加入 PSEUDOFS 的支持。<br/>options &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;GEOM_GPT &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;# GUID Partition Tables.<br/>这个选项提供了在磁盘上使用大量的分区的能力。<br/>options &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;COMPAT_43 &nbsp; &nbsp; &nbsp; &nbsp; # Compatible with BSD 4.3 [KEEP THIS!]<br/>使系统兼容4.3BSD。不要去掉这一行，不然有些程序将无法正常运行。<br/>options &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;COMPAT_FREEBSD4 &nbsp; # Compatible with FreeBSD4<br/>为了支持在旧版本的FreeBSD下编译的程序，该选项在FreeBSD 5.X i386™和Alpha systems下需要打开。<br/>最好在所有的i386和Alpha systems下打开这个选项，因为可能要运行老应用程序。<br/>在5.X才开始支持的平台，比如ia64和Sparc64®，就不需要这个选项。<br/>options &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;SCSI_DELAY=5000 &nbsp;# Delay (in ms) before probing SCSI<br/>这将让内核在探测每个 SCSI 设备之前等待 5 秒。 如果您只有 IDE 硬盘驱动器，<br/>就可以不管它， 反之您可能会希望尝试降低这个数值以加速启动过程。<br/>当然， 如果您这么做之后 FreeBSD 在识别您的 SCSI 设备时遇到问题， 则您还需要再把它改回去。<br/>options &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;KTRACE &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;# ktrace(1) support<br/>这个选项打开内核进程跟踪，在调试时很有用。<br/>options &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;SYSVSHM &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; # SYSV-style shared memory<br/>提供System V共享内存(SHM)的支持，最常用到SHM的应该是X Window的XSHM延伸，<br/>不少绘图相关程序会自动使用SHM来提供额外的速度。如果您要使用X Window，您最好加入这个选项。<br/>options &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;SYSVMSG &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; # SYSV-style message queues<br/>支持 System V 消息。 这只会在内核中增加数百字节的空间占用。<br/>options &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;SYSVSEM &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; # SYSV-style semaphores<br/>支持System V 信号量， 不常用到， 但只在kernel中占用几百个字节的空间。<br/>注意: ipcs(1) 命令的 -p 选项可以显示出任何用到这些 System V 机制的进程。<br/>options &nbsp; &nbsp; &nbsp; &nbsp; _KPOSIX_PRIORITY_SCHEDULING # POSIX P1003_1B real-time extensions<br/>在 1993 年 POSIX® 添加的实时扩展。 在 Ports Collection 中某些应用程序会用到这些 （比如StarOffice™）。<br/>options &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;KBD_INSTALL_CDEV &nbsp;# install a CDEV entry in /dev<br/>这个选项与键盘有关。 它在 /dev 中安装一个 CDEV 项。<br/>options &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;AHC_REG_PRETTY_PRINT &nbsp; &nbsp; # Print register bitfields in debug<br/> &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; # output. &nbsp;Adds ~128k to driver.<br/>options &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;AHD_REG_PRETTY_PRINT &nbsp; &nbsp; # Print register bitfields in debug<br/> &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;# output. &nbsp;Adds ~215k to driver.<br/>这个选项主要用于帮助调试， 它能够给出更容易阅读的寄存器数值。<br/>options &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;ADAPTIVE_GIANT &nbsp; &nbsp;# Giant mutex is adaptive.<br/>内核全局锁 (Giant) 是一种互斥机制 (休眠互斥体) 的名字， 它用于保护许多内核资源。<br/>现在， 这已经成为了一种无法接受的性能瓶颈， 它已经被越来越多地使用保护单个资源的锁代替。<br/>ADAPTIVE_GIANT 选项将使得内核全局锁作为一种自适应自旋锁。这意味着， <br/>当有线程希望锁住内核全局锁互斥体， 但互斥体已经被另一个 CPU 上的线程锁住的时候， <br/>它将继续运行， 直到那个线程释放锁为止。 一般情况下，另一个线程将进入休眠状态并等待下一次调度。<br/>如果您不确定是否应该这样做的话，一般应该打开它。<br/>device &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;apic &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; # I/O APIC<br/>apic 设备将启用使用 I/O APIC 作为中断发送设备的能力。 apic 设备可以被 UP 和 SMP 内核使用， 但 SMP 内核必须使用它。 要支持多处理器， 还需要加上 options SMP。<br/>device &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;eisa<br/>如果您的主机板上有EISA总线，加入这个设置。使用这个选项可以自动扫描并设置所有连接在EISA总线上的设备。<br/>device &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;pci<br/>如果您的主板有PCI总线，就加入这个选项。使用这个选项可以自动扫描PCI卡，并在PCI到ISA之间建立通路。<br/># Floppy drives<br/>device &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;fdc<br/>这是软驱控制器。<br/># ATA and ATAPI devices<br/>device &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;ata<br/>这个驱动器支持所有ATA和ATAPI设备。您只要在内核中加入device ata选项，<br/>就可以让内核支持现代计算机上的所有PCI ATA/ATAPI设备。<br/>device &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;atadisk &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; # ATA disk drives<br/>这个是ATAPI 磁盘驱动器所必须的。<br/>device &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;ataraid &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; # ATA RAID drives<br/>这个选项需要 device ata， 它用于 ATA RAID 驱动。<br/>device &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;atapicd &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; # ATAPI CDROM drives<br/>这个是ATAPI CDROM驱动器所必须的。<br/>device &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;atapifd &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; # ATAPI floppy drives<br/>这个是ATAPI 磁盘驱动器所必须的。<br/>device &nbsp;
