      "message": "x86: early boot debugging via FireWire (ohci1394_dma\u003dearly)\n\nThis patch adds a new configuration option, which adds support for a new\nearly_param which gets checked in arch/x86/kernel/setup_{32,64}.c:setup_arch()\nto decide wether OHCI-1394 FireWire controllers should be initialized and\nenabled for physical DMA access to allow remote debugging of early problems\nlike issues ACPI or other subsystems which are executed very early.\n\nIf the config option is not enabled, no code is changed, and if the boot\nparamenter is not given, no new code is executed, and independent of that,\nall new code is freed after boot, so the config option can be even enabled\nin standard, non-debug kernels.\n\nWith specialized tools, it is then possible to get debugging information\nfrom machines which have no serial ports (notebooks) such as the printk\nbuffer contents, or any data which can be referenced from global pointers,\nif it is stored below the 4GB limit and even memory dumps of of the physical\nRAM region below the 4GB limit can be taken without any cooperation from the\nCPU of the host, so the machine can be crashed early, it does not matter.\n\nIn the extreme, even kernel debuggers can be accessed in this way. I wrote\na small kgdb module and an accompanying gdb stub for FireWire which allows\nto gdb to talk to kgdb using remote remory reads and writes over FireWire.\n\nAn version of the gdb stub fore FireWire is able to read all global data\nfrom a system which is running a a normal kernel without any kernel debugger,\nwithout any interruption or support of the system\u0027s CPU. That way, e.g. the\ntask struct and so on can be read and even manipulated when the physical DMA\naccess is granted.\n\nA HOWTO is included in this patch, in Documentation/debugging-via-ohci1394.txt\nand I\u0027ve put a copy online at\nftp://ftp.suse.de/private/bk/firewire/docs/debugging-via-ohci1394.txt\n\nIt also has links to all the tools which are available to make use of it\nanother copy of it is online at:\nftp://ftp.suse.de/private/bk/firewire/kernel/ohci1394_dma_early-v2.diff\n\nSigned-Off-By: Bernhard Kaindl \u003cbk@suse.de\u003e\nTested-By: Thomas Renninger \u003ctrenn@suse.de\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\n"
