Kernel Compiles to Support HIGHMEM and SMP

next up previous contents index

Eventually the standard package kernel-image-2.4.20-1-686-smp was installed, providing both SMP and HIMEM support.

Previous kernel compiles are outlined here. 



  # wajig install bin86 kernel-package kernel-source-2.4.16 debconf-utils
  # cd /usr/src
  # tar jxvf kernel-source-2.2.16.tar.bz2
  # cd kernel-source-2.2.16
  # cp /boot/config-2.4.16-586 .config
  # make menuconfig
    Processor Type and Features
      CONFIG_MPENTIUMIII=y
      CONFIG_HIGHMEM4G=y (originally off)
      CONFIG_SMP=y (already set)
  # make-kpkg clean
  # make-kpkg --append-to-version -p3hmsmp --revision dha01 
              --initrd kernel_image


The aim was to have:

  1. dpt_i2o provided by the kernel (2.4.14 on with CONFIG_SCSI_DPT_I2O=m)
  2. support for 2 CPUs (CONFIG_SMP=y)
  3. support over 1GB memory (CONFIG_HIGHMEM4G=y)

With the new kernels the initrd (initial ram disk) is the default, so it is worth moving to this. It requires changes to your /etc/lilo.conf to include initrd lines. For example: 

  image=/boot/vmlinuz-2.4.16-p3hmsmp
        label=2.4.16-p3hmsmp
        read-only
        initrd=/boot/initrd.img-2.4.16-p3hmsmp
        append="noapic"


Note also that with the dual processor card in this machine (ASUS CUV4X-DLS) the noapic option was required, otherwise there is a problem with running out of IRQs and the boot hangs after the following message: 



  ENABLING IO-APIC IRQs
  Setting 2 in the phys_id_present_map
  ...changing IO-APIC physical ID to 2 ... ok.
  ..TIMER: vector=0x31 pin1=2 pin2=0


An alternative to turning APIC off is to free up the IRQs used by the PCI IDE devices. This is only useful if either the primary or secondary IDE is not being used (for IDE hard disks and IDE CD-ROM). To turn it off the secondary or both IDEs in the BIOS setup, go to Advanced$rightarrow$Chip Configuration$rightarrow$Onboard PCI IDE and set it to either Primary or Disabled.
