2007-02-08ieee1394: video1394: DMA fixDavid Moore1-0/+8
This together with the phys_to_virt fix in lib/swiotlb.c::swiotlb_sync_sg fixes video1394 DMA on machines with DMA bounce buffers, especially Intel x86-64 machines with > 3GB RAM.

2006-12-07ieee1394: Consolidate driver registeringBen Collins1-5/+1
This patch consolidates some bookkeeping for driver registering. It closely models what pci_register_driver() does. The main addition is that the owner of the driver is set, so we get a proper symlink for /sys/bus/ieee1394/driver/*/module. Also moves setting of name and bus type into nodemgr. Because of this, we can remove the EXPORT_SYMBOL for ieee1394_bus_type, since it's now only used in ieee1394.ko. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
2006-12-07video1394: remove BKL contentionDaniel Drake1-24/+6
video1394 does not need to take the BKL. The data structures shared between file_operations and interrupts are already protected through context-specific spinlocks. The only other danger is video1394_release() being called during another operation, however this cannot happen because release is only ever invoked when the last thread has closed the fd.

2006-12-07video1394: small optimizations to frame retrieval codepathDaniel Drake1-8/+10
Add some GCC branch prediction optimizations to unlikely error/safety conditions in the ioctl handling code commonly called during an application's capture loop. Signed-off-by: Daniel Drake <ddrake@brontes3d.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
2006-09-17ieee1394: safer definition of empty macrosStefan Richter1-1/+1
A deactivated macro, defined as "#define foo(bar)", will result in silent corruption if somebody forgets a semicolon after a call to foo. Replace it by "#define foo(bar) do {} while (0)" which will reveal any respective syntax errors. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

2006-06-12video1394: be quietBen Collins1-8/+8
When working with multiple cameras and intensive applications, our logs get flooded with video1394 information which isn't of much interest. Any objections to demoting these messages to debug messages? Signed-off-by: Daniel Drake <dsd@gentoo.org> Signed-off-by: Ben Collins <bcollins@ubuntu.com>

These days ioctl32.h is only used for communication of fs/compat.c and fs/compat_ioctl.c and doesn't contain anything of interest to drivers. Remove inclusion in various drivers.

2005-04-16Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds1-0/+1527
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
