Hello, I have added 1GB RAM to a linux machine so now it uses 2 GB RAM. I see in "cat /proc/meminfo" only 1GB in MemTotal. I have x86_64 machine running Fedora Core 6. My question is: should I build a kernel with special configuration when trying to use more than 1GB of RAM ?
Config you kenrel to use Highmem. It can be selected while compiling the kernel under processor types and features -> highmem support -> make it 4 GB .
I tried googling for it; in many places I saw talks about setting one of the following: CONFIG_HIGHMEM4G CONFIG_HIGHMEM64G CONFIG_HIGHMEM Moreover, I saw many places where it says that this should be in "Processor type and features" in make menuconfig. However, I tried "make menuconfig" (with a new kernel , 2.6.21-rc7) and I did not saw these options.
answered above. thanks --psr
Also trying to edit .config and look for it did not find it. Any ideas? am I missing something ? Regards, Ian -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
