Howto configure the Linux kernel / arch / powerpc / platforms / prep




  • Option: PREP_RESIDUAL
    • Kernel Versions: 2.6.15.6 ...
    • (on/off) Support for PReP Residual Data
    • depends on PPC_PREP
      Some PReP systems have residual data passed to the kernel by the firmware. This allows detection of memory size, devices present and other useful pieces of information. Sometimes this information is not present or incorrect, in which case it could lead to the machine behaving incorrectly. If this happens, either disable PREP_RESIDUAL or pass the 'noresidual' option to the kernel.
      If you are running a PReP system, say Y here, otherwise say N.


  • Option: PROC_PREPRESIDUAL
    • Kernel Versions: 2.6.15.6 ...
    • (on/off) Support for reading of PReP Residual Data in /proc
    • depends on PREP_RESIDUAL && PROC_FS
      Enabling this option will create a /proc/residual file which allows you to get at the residual data on PReP systems. You will need a tool (lsresidual) to parse it. If you aren't on a PReP system, you don't want this.
