|
# To configure the Linux kernel yourself run
|
|
#
|
|
# make _menuconfig
|
|
#
|
|
# first, afterwards proceed with the normal port installation. This
|
|
# is optional.
|
|
#
|
|
# By default the Linux config file is saved in work/linux-config. You
|
|
# can override it by setting LINUX_KCONFIG. If you need it later copy
|
|
# it somewhere else before running make clean, or it's gone!
|
|
#
|
|
# To use an existing Linux config file pass the absolute path with
|
|
# LINUX_KCONFIG=/path/to/linux/config to the port (on the command line
|
|
# or via /etc/make.conf). Enabling either the XEN or KVM option will
|
|
# merge the KVM/XEN-specific default config with your own.
|
|
#
|
|
# You can run any Makefile targets of Linux by prefixing it with an
|
|
# underscore (_). This setups a build environment for you so has
|
|
# benefits over going to ${WRKSRC} yourself.
|
|
#
|
|
# You won't be able to build 64-bit kernels on FreeBSD/i386. gcc is
|
|
# missing support for this.
|
|
#
|
|
# By default the kernel is installed into ${PREFIX}/linux-kernel.
|
|
# Override by setting LINUX_INSTALL_PATH. Same for kernel modules and
|
|
# LINUX_MOD_INSTALL_PATH.
