* Driver Core: add ability for class_find_device to start in middle of listGreg Kroah-Hartman2008-07-22
| | | | | | | | | | | | | | | This mirrors the functionality that driver_find_device has as well. We add a start variable, and all callers of the function are fixed up at the same time. The block layer will be using this new functionality in a follow-on patch. Cc: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

I suspect that this is due to DMA not succeeding in time. If the transmit fifo can't contain more than one packet (big packets), the DMA should provide a new packet each cycle (125us). I am under the impression that my current PCI express test system can't guarantee this. In any case, the patch tries to provide a workaround as follows: The DMA program descriptors are modified such that when an error occurs, the DMA engine retries the descriptor the next cycle instead of stalling. This way no data is lost. The side effect of this is that packets are sent with one cycle delay. This however might not be that much of a problem for certain protocols (e.g. AM824). If they use padding packets for e.g. rate matching they can drop one of those to resync the streams. The amount of skips between two userspace wakeups is counted. This number is then propagated to userspace through the upper 16 bits of the 'dropped' parameter. This allows unmodified userspace applications due to the following: 1) libraw simply passes this dropped parameter to the user application 2) the meaning of the dropped parameter is: if it's nonzero, something bad has happened. The actual value of the parameter at this moment does not have a specific meaning. A libraw client can then retrieve the number of skipped cycles and account for them if needed.

* 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).
