* ieee1394: prevent device binding of raw1394, video1394, dv1394Stefan Richter2008-04-18
| | | | | | | | | | | | These drivers don't need to match any unit_directory type device. They just need the id_table for module autoloading per module alias. Not binding any of these drivers allows special-purpose drivers with similar or same IDs to bind to devices.

* ieee1394: sbp2: raise default transfer size limitStefan Richter2008-01-30
| | | | | | | | | | | | | | | | | | | | | | | This patch speeds up sbp2 a little bit --- but more importantly, it brings the behavior of sbp2 and fw-sbp2 closer to each other. Like fw-sbp2, sbp2 now does not limit the size of single transfers to 255 sectors anymore, unless told so by a blacklist flag or by module load parameters. Only very old bridge chips have been known to need the 255 sectors limit, and we have got one such chip in our hardwired blacklist. There certainly is a danger that more bridges need that limit; but I prefer to have this issue present in both fw-sbp2 and sbp2 rather than just one of them. An OXUF922 with 400GB 7200RPM disk on an S400 controller is sped up by this patch from 22.9 to 23.5 MB/s according to hdparm. The same effect could be achieved before by setting a higher max_sectors module parameter. On buses which use 1394b beta mode, sbp2 and fw-sbp2 will now achieve virtually the same bandwidth. Fw-sbp2 only remains faster on 1394a buses due to fw-core's gap count optimization. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

* x86: early boot debugging via FireWire (ohci1394_dma=early)Bernhard Kaindl2008-01-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a new configuration option, which adds support for a new early_param which gets checked in arch/x86/kernel/setup_{32,64}.c:setup_arch() to decide wether OHCI-1394 FireWire controllers should be initialized and enabled for physical DMA access to allow remote debugging of early problems like issues ACPI or other subsystems which are executed very early. If the config option is not enabled, no code is changed, and if the boot paramenter is not given, no new code is executed, and independent of that, all new code is freed after boot, so the config option can be even enabled in standard, non-debug kernels. With specialized tools, it is then possible to get debugging information from machines which have no serial ports (notebooks) such as the printk buffer contents, or any data which can be referenced from global pointers, if it is stored below the 4GB limit and even memory dumps of of the physical RAM region below the 4GB limit can be taken without any cooperation from the CPU of the host, so the machine can be crashed early, it does not matter. In the extreme, even kernel debuggers can be accessed in this way. I wrote a small kgdb module and an accompanying gdb stub for FireWire which allows to gdb to talk to kgdb using remote remory reads and writes over FireWire. An version of the gdb stub fore FireWire is able to read all global data from a system which is running a a normal kernel without any kernel debugger, without any interruption or support of the system's CPU. That way, e.g. the task struct and so on can be read and even manipulated when the physical DMA access is granted. A HOWTO is included in this patch, in Documentation/debugging-via-ohci1394.txt and I've put a copy online at ftp://ftp.suse.de/private/bk/firewire/docs/debugging-via-ohci1394.txt It also has links to all the tools which are available to make use of it another copy of it is online at: ftp://ftp.suse.de/private/bk/firewire/kernel/ohci1394_dma_early-v2.diff Signed-Off-By: Bernhard Kaindl <bk@suse.de> Tested-By: Thomas Renninger <trenn@suse.de> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

| * [SCSI] relax scsi dma alignmentJames Bottomley2008-01-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch relaxes the default SCSI DMA alignment from 512 bytes to 4 bytes. I remember from previous discussions that usb and firewire have sector size alignment requirements, so I upped their alignments in the respective slave allocs. The reason for doing this is so that we don't get such a huge amount of copy overhead in bio_copy_user() for udev. (basically all inquiries it issues can now be directly mapped).

This happened to work for ia64, powerpc, sparc64 and x86 because they happened to drag in that file via their <asm/dma-mapping.h>. On most of the others this probably broke.

* ieee1394: csr1212: proper refcountingStefan Richter2007-10-16
| | | | | | | | | | | | At least since nodemgr got rid of coarse global locking, accesses to struct csr1212_keyval's reference counter should be atomic and coupled with proper barriers. Also, calls to csr1212_keep_keyval(kv) should occur before kv is being used.

| | | | | | | | | | | | | The nodemgr host thread can exit on its own even when kthread_should_stop is not true, on receiving a signal (might never happen in practice, as it ignores signals). But considering kthread_stop() must not be mixed with kthreads that can exit on their own, I think changing the code like this is clearer. This change means the thread can cut its sleep short when receive a signal but looking at the code around, that sounds okay (and again, it might never actually recieve a signal in practice).
