  • 19f1537b7   Lguest support for Virtio ... Browse Code »

    This makes lguest able to use the virtio devices.

    We change the device descriptor page from a simple array to a variable
    length "type, config_len, status, config data..." format, and
    implement virtio_config_ops to read from that config data.

    We use the virtio ring implementation for an efficient Guest Host
    virtqueue mechanism, and the new LHCALL_NOTIFY hypercall to kick the
    host when it changes.

    We also use LHCALL_NOTIFY on kernel addresses for very very early
    console output. We could have another hypercall, but this hack works
    quite well.

  • 15045275c   Remove old lguest I/O infrrasructure. ... Browse Code »

    This patch gets rid of the old lguest host I/O infrastructure and
    replaces it with a single hypercall "LHCALL_NOTIFY" which takes an
    address.

    The main change is the removal of io.c: that mainly did inter-guest
    I/O, which virtio doesn't yet support.

  • 0ca49ca94   Remove old lguest bus and drivers. ... Browse Code »

    This gets rid of the lguest bus, drivers and DMA mechanism, to make
    way for a generic virtio mechanism.

    Separate i386 architecture specific from core.c and move it to
    x86/core.c and add x86/lguest.h header file to match.

  • 1f4e1de4f   Rename switcher.S to x86/switcher_32.S ... Browse Code »

    lguest uses a "switcher" shim mapped high to bounce between host and
    guest. As lguest becomes less i386-centric, we separate this code
    into a subdir.

  • 34b8867a0   Move lguest guest support to arch/x86. ... Browse Code »

    Lguest has two sides: host support (to launch guests) and guest
    support (replacement boot path and paravirt_ops). This moves the
    guest side to arch/x86/lguest where it's closer to related code.

  • f938d2c89   lguest: documentation I: Preparation ... Browse Code »

    The netfilter code had very good documentation: the Netfilter Hacking HOWTO.
    Noone ever read it.

    So this time I'm trying something different, using a bit of Knuthiness.
