 Posted: Fri May 22, 2015 12:44 am Post subject: SOLVED building kernel on x86_64 arch results in x86 bzImage |
 |
|
Hi everyone,
I'm completely confused. I've built many kernels before, and am installing a brand new install and I'm completely stumped. Can someone say what I'm missing? I am trying to build a kernel image, and make keeps on giving me an x86 kernel, instead of an x86_64 one. I even tried
| Code: | | make ARCH=x86_64 menuconfig |
without luck. I can paste the entire config output, but a snippet that I think is most important:
| Code: |
CONFIG_GENTOO_LINUX_INIT_SCRIPT=y
# CONFIG_GENTOO_LINUX_INIT_SYSTEMD is not set
CONFIG_64BIT=y
CONFIG_X86_64=y
CONFIG_X86=y
CONFIG_INSTRUCTION_DECODER=y
CONFIG_PERF_EVENTS_INTEL_UNCORE=y
CONFIG_OUTPUT_FORMAT="elf64-x86-64"
CONFIG_ARCH_DEFCONFIG="arch/x86/configs/x86_64_defconfig"
|
I have a 2x Core 2 Xeon board, my stage3 image is | Code: | | stage3-amd64-20150521.tar.bz2 |
make.conf:
| Code: | CHOST="x86_64-pc-linux-gnu"
CFLAGS="-march=core2 -O2 -pipe"
CXXFLAGS="${CFLAGS}"
MAKEOPTS="-j5"
# These are the USE flags that were used in addition to what is provided by the
# profile used for building.

Any help is greatly appreciated. What am I missing?

Shouldn't a 64-bit kernel generate the files in arch/x86_64/bzImage? When the make script runs, I only see
being compiled, nothing for

Also, the top of make menuconfig results in:

So I'm just paranoid and this is as expected?

Thanks Jaglover, I've been doing this for so many years and just never paid attention before.
Thx on the point of the CPU_FLAGS_X86, does it make sense to rebuild the kernel image with them added or doesn't really matter?

If you have a Intel Xeon processor, Why you use kernel AMD in you instalation?
This is possible?

amd64 is the general arch for x86_64. It is historically amd64 because AMD created the 64-bit first, Intel followed.
