Hi All,
I am using the config-2.6.x file from Red Hat installation (RHEL5.4 x86_64). I copying the config file to /usr/src/<root_dir_2.6.34>. Checking the .config using menuconfig. The generic x86_64 support is turned on. Executing the following commands in sequence: make bzImage, make modules, make modules_install.
Now I check the arch/x86_64/boot/bzImage and see that it is symbolically linked to arch/x86/boot/bzImage.
file bzImage of x86/boot directory reveals that it is 32 bit executable:
../x86/boot/bzImage: Linux kernel x86 boot executable RO-rootFS, swap_dev 0x2, Normal VGA
However the Red Hat kernel is 64 bit. ( file /boot/vmlinuz-2.6.18-164.11.1.el5
/boot/vmlinuz-2.6.18-164.11.1.el5: ELF 64-bit LSB shared object, AMD x86-64, version 1, stripped)
In order to get 64 bit kernel, what features are to be turned on in the .config file. This topic came up in the mailing list discussion about 5 weeks back. Unfortunately, I could not retrieve the info.
Please advise. Any help to resolve this issue is apprecitaed.
Thanks,
A>K
