    Subject[ANNOUNCE] firescope for i386/x86-64 released
    Date

    [This has been on ftp for some time but I didn't get around to announce it]

    I ported Ben Herrenschmidt's firescope tool to i386/x86-64 and did
    some changes. It allows to read memory from a target over firewire.
    All you need is a fitting firewire cable and two machines with firewire
    port and ohci1394 firewire controllers.

    There's no xmon on x86-64, so it's primarily to read the dmesg log buffer
    (but it can read arbitary memory). It's very useful to get
    kernel logs out of machines without serial port like laptops.

    ftp://ftp.suse.com/pub/people/ak/firescope/firescope-0.1.tar.gz

    See the manpage in the package for more details.

    Limitations:
    - raw1394 needs to be loaded on the host
    - Host needs to run ohci1394 first. This means it currently
    cannot be used to capture very early oopses.
    - Host needs to be same bitsize as target. You can use a 32bit
    binary (firescope32 as generated by the Makefile), but you need
    2.6.17rc1 for the compat support
    - The tty output inserts too many newlines.
    - Under high load auto update mode sometimes gets confused
    (it is hard to do this without any locking)
