  • ed3c66144   iSCSI/iBFT: use proper address translation ... Browse Code »

    In virtual environments (namely, Xen Dom0) virt phys and
    virt isa-bus translations cannot be freely interchanged (and
    even outside such environments it is not really correct to do so).
    When looking at memory below 1M, the latter translations should
    always be used.

  • 138fe4e06   Firmware: add iSCSI iBFT Support ... Browse Code »

    Add /sysfs/firmware/ibft/[initiator|targetX|ethernetX] directories along with
    text properties which export the the iSCSI Boot Firmware Table (iBFT)
    structure.

    What is iSCSI Boot Firmware Table? It is a mechanism for the iSCSI tools to
    extract from the machine NICs the iSCSI connection information so that they
    can automagically mount the iSCSI share/target. Currently the iSCSI
    information is hard-coded in the initrd. The /sysfs entries are read-only
    one-name-and-value fields.

    The usual set of data exposed is:

    # for a in `find /sys/firmware/ibft/ -type f -print`; do echo -n "$a: "; cat $a; done
