i am trying to build a server for one of my customer.
the hardware is a HP ProLiant DL165, with an 8 core AMD Opteron 6128 and 4GB RAM. the server MUST run under Debian 5 (Lenny) due to a software dependency.
the standard Debian kernel does not support the 8 cores of the opteron and i am forced to use the
nosmp boot option, which renders the processor quite useless by using only 1 core…
i read somewhere that i need a bigsmp kernel in order for my distro to support the 8 cores. is it true ? where can i find a bigsmp kernel for Debian 5 ? if i can’t find a ready-made one, how do i build a bigsmp kernel ? which config options are relevant ?
A 64-bit kernel shouldn’t have this problem. It will support all 8 cores. If you’re stuck with 32-bit for some reason, the BigSMP kernel is what you’ll need to make it work.
