把下面的文字复制到新建文本文件,并保存文件名为 Makefile.cpu
# CPU tuning section - shared with UML.
# Must change only cflags-y (or [yn]), not CFLAGS! That makes a difference for UML.
#-mtune exists since gcc 3.4, and some -mcpu flavors didn't exist in gcc 2.95.
HAS_MTUNE := $(call cc-option-yn, -mtune=i386)
ifeq ($(HAS_MTUNE),y)
tune = $(call cc-option,-mtune=$(1),)
else
tune = $(call cc-option,-mcpu=$(1),)
endif

cflags-$(CONFIG_MK6) += -march=k6
# Please note, that patches that add -march=athlon-xp and friends are pointless.
# They make zero difference whatsosever to performance at this time.
cflags-$(CONFIG_MK7) += $(call cc-option,-march=athlon,-march=i686 $(align)-functions=4)
cflags-$(CONFIG_MK += $(call cc-option,-march=k8,$(call cc-option,-march=athlon,-march=i686 $(align)-functions=4))

# Geode GX1 support
cflags-$(CONFIG_MGEODEGX1) += $(call cc-option,-march=pentium-mmx,-march=i486)
并把该文件复制到 /lib/modules/2.6.15-rc5/build/arch/i386下面,再安装,
当 Nvidia XXX.run 提示没有合适的kernel要从网上下载时,选no,其他的都yes
就 ok了 |
