Kernel tips

We (RTAI team) still receive email about problems related with the creation of the RTAI kernel. Most of the problems are not related with RTAI but only with kernel configuration.
Users can start from my config and add the drivers needed by their hardware. My kernel already contains the “ext3″ filesystem, thus it is not necessary to create an “initial ramdisk” to boot the system.
Users can detect their specific modules by simply run a “generic” kernel (normally the kernel installed by the distribution) and by launching the command

lspci -v

from a shell. This command lists the hardware of the siystem including the used linux drivers

After opening and loaded my kernel configuration (“make xconfig” or “make menuconfig” + “Load file”) the kernel must be configured to fit the user’s system.

Already included in my configuration:

  • ext3 file system
  • USB support (ehci_hcd and uhci_hcd)
  • My SATA driver (ata_piix)
  • My Wireless LAN (iwlagn)
  • My network card (e1000e)

Not included in my configuration:

  • PS/2 mouse
  • Your network card
  • Your ATA or SATA drivers
  • Your Wireless network card
  • USB driver ohci_hcd

The menu “Find” under “make xconfig” or the key “/” under “make menuconfig” allows to search about a specific driver and see if it is already installed or not.
