  • d6551e884   [ARM] Add thread_notify infrastructure ... Browse Code ยป

    Some machine classes need to allow VFP support to be built into the
    kernel, but still allow the kernel to run even though VFP isn't
    present. Unfortunately, the kernel hard-codes VFP instructions
    into the thread switch, which prevents this being run-time selectable.

    Solve this by introducing a notifier which things such as VFP can
    hook into to be informed of events which affect the VFP subsystem
    (eg, creation and destruction of threads, switches between threads.)
