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" }, { "commit": "e658bc556b3b2e699c5d9ba65fcc955f35105f42", "tree": "3332ec347fd566100f272adcdef4d88f78085718", "parents": [ "d395a1774f34600d72f7d3796716f350ef29584b" ], "author": { "name": "Adrian Bunk", "email": "bunk@stusta.de", "time": "Tue Jan 02 22:56:53 2007 +0100" }, "committer": { "name": "Stefan Richter", "email": "stefanr@s5r6.in-berlin.de", "time": "Thu Feb 08 20:57:43 2007 +0100" }, "message": "the scheduled IEEE1394_OUI_DB removal\n\nThis patch contains the scheduled IEEE1394_OUI_DB removal.\n\nSigned-off-by: Adrian Bunk \u003cbunk@stusta.de\u003e\n\nUpdate: Also remove drivers/ieee1394/.gitignore.\nRemove now unused struct members in drivers/ieee1394/nodemgr.h.\n\nSigned-off-by: Stefan Richter \u003cstefanr@s5r6.in-berlin.de\u003e\n" }, { "commit": "def4d8733b8b8fed521957a7fd546714dd491b91", "tree": "5a9833faf86de150fd55ef1dd799f908cc061c9a", "parents": [ "7f5880394c8ab01854c0cba288352a1a77d5ea82" ], "author": { "name": "Randy Dunlap", "email": "randy.dunlap@oracle.com", "time": "Tue Oct 24 11:19:11 2006 -0700" }, "committer": { "name": "Stefan Richter", "email": "stefanr@s5r6.in-berlin.de", "time": "Thu Dec 07 21:32:29 2006 +0100" }, "message": "ieee1394: only build OUI database files if config enabled\n\nOnly build IEEE1394 OUI database files if the config option is enabled.\n\nSigned-off-by: Randy Dunlap \u003crandy.dunlap@oracle.com\u003e\nSigned-off-by: Stefan Richter \u003cstefanr@s5r6.in-berlin.de\u003e\n" }, { "commit": "7301c8d3a05dc52d33598364da7c4eb6ab6357eb", "tree": "715c5caaa11427e0c0a736692ebee156317588f2", "parents": [ "ef797546a93fffa9d8508e7c8539b352b6678568" ], "author": { "name": "Jody McIntyre", "email": "scjody@steamballoon.com", "time": "Fri Nov 18 00:16:26 2005 -0500" }, "committer": { "name": "Jody McIntyre", "email": "scjody@modernduck.com", "time": "Fri Nov 18 00:16:26 2005 -0500" }, "message": "Remove amdtp, cmp drivers.\n\nRemove the Audio and Music Data Transmission Protocol driver and the\nConnection Management Procedures driver.
